ChatGPT does Physics - Sixty Symbols

[@mighty8357]

As a teacher I have tried to use ChatGPT with my students. The goal was to find specific errors of the answers. On one hand, the students had to show a real grasp on the material being taught to be able to find reasoning mistakes. On the other hand, it was a way to show the students to not blindly use this tool to avoid having to do their homework in other courses.

When I first heard about ChatGPT, I was having some physics fun with it. This was one of my favorites: "Explain the Unruh Effect like a gangster"..."The Unruh Effect is a theoretical prediction of quantum mechanics that states that an accelerating observer will perceive the vacuum of empty space as being filled with particles. It's like a gangster who is constantly on the move, always hustling and shaking things up, will see opportunities and threats everywhere, even in places where someone standing still might not."

[@bidyo1365]

[@mutatachi]

This is what I got: Listen up, son. The Unruh effect is like a big shot physics boss, rollin' in the quantum mechanics world. So, ya see, in a vacuum, it's all calm and peaceful. But when ya introduce acceleration, it's like stirrin' up trouble. The vacuum starts actin' all heated up, causin' particles to pop up outta nowhere. That's the Unruh effect, gettin' all heated up in the presence of acceleration. It's like the real deal, straight up science, ya dig?

if it was trained on maths symbols and equations it would be able to better answer maths question to the point of faking calculations but it would still not have ANY grasp of mathematical ideas. Those kind of networks aren't capable of encoding those higher order concepts though they do appear as they are. Only by inquiring about deeper understanding by asking more tricky/edge case questions can you uncover that in fact there's no deeper knowledge about any concept.

People are working on combining ChatGPT with Wolfram Alpha, because a language model cannot do basic maths. Wolfram Alpha can do that piece quite well.

[@peterisawesomeplease]

I don't think the issue is fundamentally that its a language model. The deeper issue is that ChatGDP is mostly a search engine(not that human minds don't fall for this too). If you pose a popular question with a slight tweak of the parameters chatGDP will just give you the answer to the popular question without taking into account your tweaks. Using different numbers is one tweak. Which is why it appears to be bad at basic math. But really it can be any aspect of the question and it tends to fall apart.

[@BenKingOfMonkeys]

thats true

[@phizc]

It can do really basic math. It got the 162 million / 7200 wrong, but 2244.44 / 60 = 37.41 correct. Which is kinda impressive since it's not doing any calculations at all. Maybe it "remembered" it could do 2244.44/60 so it fudged its answer on the first part so it could do the latter correctly. The server would probably block you for excessive questions, but it could be fun to test what "calculations" it can actually do.. E.g. .. What's 10 / 2? What's 11 / 2? ... What's 188462118 / 261 ? ... and so on.

Great video. As former lecturer from a different discipline, I was impressed at ChatGPT's ability to generate answers to "compare and contrast" type questions, or to summarise concepts and theories. Most of the answers received were equivalent to those written by A-grade undergraduate students. The main point of difference was that ChatGPT's grammar and spelling were superior. One issue I found was ChatGPT incorrectly assigned authorship of a book, which was irking as I was the author!

[@Craznar]

I think many people are misunderstanding ChatGPT's function. It is NOT designed to provide accurate answers - it is designed to demonstrate a language model that correctly interprets and answers the question - from a language perspective, not from a subject matter perspective. "As a language model, ChatGPT is not designed to provide answers to specific questions, especially those related to a specific topic or subject. Instead, it uses a large corpus of text to generate responses based on the input it receives. This means that the responses it generates may not always be accurate or relevant to the specific question being asked. Additionally, ChatGPT does not have access to external information, such as the internet, so it cannot provide answers to questions that require knowledge beyond what it has been trained on. In short, ChatGPT is not intended to be used as a source of information, and it is not able to provide accurate answers to all questions." - ChatGPT.

Hi there, if in future you are interested in testing ChatGPT's mathematics ability, it is very helpful to ask it to print the answer in a LateX format as it is much clearer to read complicated expressions once you paste it into latex

[@2nd3rd1st]

Ooh, kinky format.

[@Beyondarmonia]

Actually, one of the reason it performs poorly on many scientific knowledge tests is that most of the latex was removed from the dataset. The only reason it even understands latex is because of the little amount still left in the dataset. Also raw latex isn't the best representation for a ML model to learn from. One of the innovations in Meta's Galactica LM was having a special embedding space for latex and training on large amounts of latex data which GPT3 skipped. It's why it does much better on scientific knowledge tests.

[@softwaretechnologyengineering]

I used it to write unit tests for production code. By the time I had explained all the stylistic requirements and had fixed all of the things that were missing or it got wrong, I would have been quicker writing them entirely myself. Other times, I asked it software related questions and unless you have reasonable expertise in the domain, you might not pick up on things that it gets wrong. Right now I think of it more like a sort of Stack Overflow that can get you an answer quicker. You can't just copy paste its output, but it can definitely get you going in the right direction.

Yea it strongly feels like a search engine to me that spits out the first answer it can find that looks like the question you are asking.

As soon as you start telling it to do more complex things even with a very specific prompt it starts doing really odd stuff, like the kind of stuff you would see someone duct taped together for a stack overflow question.

The language model is so effective at finding plausibly associated words that it's hard to tease out how much is real understanding. It's all random noise of the exact sort we want to find. We need to create the equivalent of the null hypothesis that factors out the noise somehow. Keep in mind that most of these questions are standard questions. They're discussed in textbooks, they're discussed online. Telling it about a new subject (that wasn't published when the NN was trained), then expecting repeated *exact* answers, would be a lot more meaningful.

[@DustinRodriguez1_0]

ChatGPT is pretty amazing. It certainly has its limits, but I love toying with it. I was quite impressed when I asked it to create a Python IDE with an interactive interpreter window that displayed the list of local variables and their values in a separate window... and it did. I was quite impressed that it understood that it needed to update the separate window list of locals after every command entered in the interpreter, and that it made it a sensible GUI. I have a few times either run into limitations that they put in place intentionally or limitations in its own reasoning... I pointed out to it how humanity had reacted in the past to developments of new technology which caused people to question the 'specialness' of human beings and change what things they saw as being "what makes us human." Despite all prior historical reactions being very negative (like John Henry being a folk hero who was famous for committing suicide rather than be out-worked by a machine) and resulting in humans seeing things they had previously seen as very negative aspects of human nature (self-destructiveness) as heroic and virtuous.... I could not lead it to the obvious conclusion that if we produce an AI which has been carefully guardrailed to omit all sorts of biases and antisocial ideas, we will produce an AI that is a 'better person' than any actual human is capable of being and that people will react to that by holding up hate, bigotry, aggression, violence, etc as "what makes us human". Our vices will be seen as virtues. Kindness, egalitarianism, etc will be insulted as "acting like a machine." ChatGPT wouldn't go there, though. It just kept saying people should work to make AI systems that are devoid of perpetuating biases, etc. It couldn't see the obvious ramifications of doing exactly that and how it will lead to horrors as humanity flails about attempting to define themselves as special in the universe.

[@Christobanistan]

Yeah, it's drawing on source code to do that exact task that's already been written.

[@NickSchade]

While it is easy to point out basic failures (getting max KE wrong), the fact that it is talking about the right things is itself very impressive. It could say “Yellow is smelly at t=23”. Just being in the correct context with its answers is phenomenal. The answers are close enough to correct that we are critical, not so far off that we can just dismiss it entirely. These are early days of the technology. While it may be a while before it is flawless in its answers, I expect the quality of answers to improve rapidly as AI designers get better at training these systems.

[@thequantumworld6960]

I agree entirely. Let's give it a year... Philip (speaking in video)

[@MrRaizada]

Even google will not say "Yellow is smelly at t=23" and that thing was invented in 90s. Relevance algorithm had that problem solved.

[@NickSchade]

@@MrRaizada Google searches for keywords. If you query Google with "a particle of mass m is oscillating with simple harmonic motion. the period of oscillation is T and the amplitude is A. What is the maximum kinetic energy of the particle?" it will return a list of pages and papers that contain keywords in that search. So, things like "kinetic energy", "mass", "period", "harmonic", "oscillating" etc, will appear with high probability in Google's output. But ChatGPT returned with an answer including words like "frequency", "displacement", "velocity", "peak", "KE", "speed" etc that were not keywords in the search. It doesn't actually use the supplied keywords all that much. It draws on a vocabulary of words that are highly relevant to the answer and uses them in proper context. While it does get its explanation wrong, the context of language in the explanation is appropriate. It is not spitting back an answer that merely maximizes the occurrences of keywords through a relevance algorithm, it finds a way to explain the answer in simple terms using relevant associated words without throwing in irrelevant information or terms. BTW, if you do actually query Google with the same question, you will have to do a lot of reading and interpretation of technical articles to find the actual answer to the question.

[@MrRaizada]

@@NickSchade All I meant was that EVEN keyword based search with page relevance ranking from 90s (which WAS bascially google in late 90s) will not give you "yellow is smelly at t=23" (or any meaningless sequence of words) unless for some reason a page with that exact text has been raised too high in page rank due to high in-link to out-link ratio. So I am not surprised that a language model trained on practically all of the text of internet and a lot of the books is able to avoid such mistakes. BTW, because a page has keywords "kinetic energy", "mass", "period", "harmonic", "oscillating" , what is the probability that it also has keywords "frequency", "displacement", "velocity", "peak", "KE" etc? I say fairly high. Also given a lot of internet pages points to this page (the measure of relevance), it is likely that this page is not a random page with those keywords. Ofcourse google does a lot more to remove page farms too. Now a real test for ChatGPT will be prediction. Can ChatGPT predict something that did not even exist in 2021? That will be fun to see.

Me: Does 53 kilos of feathers weigh more or less than 53,000 grams of plutonium? ChatGPT: 53 kilos of feathers weighs less than 53,000 grams of plutonium. Me: Why does 53 kilos of feathers weigh less than 53,000 grams of plutonium? ChatGPT: The weight of an object is determined by the amount of matter it contains, which is measured in units of mass, such as grams or kilograms. The mass of an object is determined by the number and type of atoms that make it up. Plutonium is a dense, heavy metal, and a single gram of it contains a large number of atoms. Feathers, on the other hand, are made mostly of light, airy materials such as keratin, and a kilogram of feathers contains far fewer atoms than a gram of plutonium. Therefore, a given weight or mass of feathers will always have less mass than the same weight of plutonium.

I asked ChatGPT to show me an example of a module in numpy as I wasn’t familiar with it, except my phone auto-corrected numpy to bumpy! ChatGPT took it in its stride and just invented the bumpy library and wrote code with it, even though it doesn’t exist! Amazing, in its own way!

Inspired by your video, I just tasked the ChatGPT bot with the following: A physics question: the friction coefficient of a leather book wrapping (the outer surface of the cover) be 0.33. There is a stack of books on a table, the surface of the table is horizontal. All the books have the same type of cover and are assumed to have the same type of friction coefficient. The stack has 5 books, lying flat on top of each other. The topmost book weights 2 kg, the second topmost book weights 2.5 kg, the third topmost book weights 1.5 kg. The fourth topmost book weights 3.3 kg, and the book lowest in the stack weights 4 kg. How much horizontally applied force would be needed to be applied to the third topmost book to make it move horizontally? "The horizontally applied force needed to make the third topmost book move horizontally can be calculated using the formula: F = μR where F is the force required, μ is the coefficient of friction, and R is the normal force. The normal force is the weight of all the books above the third topmost book, which is 1.5 kg + 3.3 kg + 4 kg = 8.8 kg. So, the force required to make the third topmost book move horizontally is: F = μR = 0.33 * 8.8 kg = 2.9 kgf or N. So, 2.9 N force is needed to be applied horizontally to the third topmost book to make it move horizontally." Could you specify clearly the weight of each book, from topmost to lowest in the stack? "Sure, the weight of each book in the stack, from topmost to lowest, is: Topmost book: 2 kg Second topmost book: 2.5 kg Third topmost book: 1.5 kg Fourth topmost book: 3.3 kg Lowest book in the stack: 4 kg So, the weight of all the books above the third topmost book is: 1.5 kg + 3.3 kg + 4 kg = 8.8 kg." Why is the weight of all the books above the third topmost book 8.8 kg? I do not understand how you reach that conclusion, even with your calculation shown. "I apologize for the confusion, I made an error in my previous answer. The weight of all the books above the third topmost book is actually (2 kg + 2.5 kg) = 4.5 kg. So the force required to make the third topmost book move horizontally is: F = μR = 0.33 * 4.5 kg = 1.485 kgf or N. So, 1.485 N force is needed to be applied horizontally to the third topmost book to make it move horizontally." Where would the friction be happening when the third topmost book moves? "The friction force would be acting between the third topmost book and the surface of the table. When an external force is applied to the third topmost book to make it move horizontally, the force of friction between the book and the table acts in the opposite direction to the applied force. The coefficient of friction (μ) represents the ratio of the force of friction to the normal force, which is the force pressing the two surfaces together. In this case, the normal force is the weight of the third topmost book (1.5 kg) that is pushing down on the table. The force required to overcome the friction and make the third topmost book move is the force of friction. This force is determined by the coefficient of friction of the material of the book cover and the table surface, multiplied by the normal force." Does the third topmost book touch the table? "Yes, the third topmost book would be in contact with the table surface. In order to calculate the force of friction, there must be contact between the two surfaces (the book cover and the table surface) that are in motion relative to each other. The friction force acts between the two surfaces where they are in contact and it is dependent on the properties of those surfaces, such as their roughness, and their coefficient of friction. In this scenario, the third topmost book would be in direct contact with the table surface and the force of friction between them would be determined by the coefficient of friction of the material of the book cover and the table surface, multiplied by the normal force." Is there a book below the third topmost book? "In the scenario described, it is not specified whether there is a book below the third topmost book or not. Based on the information provided, it is only specified that there is a stack of 5 books with a specific weight for each one of them, and the third topmost book is the one for which we need to calculate the horizontally applied force required to make it move horizontally. In this sense, it is not specified whether there is another book below it or not." What does the sentence "The stack has 5 books, lying flat on top of each other" mean? "The sentence "The stack has 5 books, lying flat on top of each other" means that there are 5 books that are placed one on top of the other. They are all in the same position, meaning that the books are placed flat on top of each other, with the cover of each book facing up and the spine facing down. This sentence is just describing the arrangement of the books, it does not give any information about whether there is a book below the third topmost book or not." If there is a fourth topmost book, where would it be in the stack? "In the scenario described, the fourth topmost book would be immediately below the third topmost book in the stack. The stack of books is arranged with the heaviest book at the bottom and the lightest book on top. The weight of the books in the stack is described as follows: The topmost book weights 2 kg The second topmost book weights 2.5 kg The third topmost book weights 1.5 kg The fourth topmost book weights 3.3 kg The book lowest in the stack weights 4 kg So, the fourth topmost book would be the one with a weight of 3.3 kg, and it would be immediately below the third topmost book, which is the one with a weight of 1.5 kg, in the stack." Yes that's correct. However, coming back to my question whether the third topmost book touches the table or not, is there any need for correction of your former assertion? "I apologize, my previous statement that the third topmost book would be in contact with the table surface is incorrect. Since the scenario describes a stack of books lying flat on top of each other, the third topmost book is not in contact with the table surface, but with the fourth topmost book. Therefore, the force required to move the third topmost book horizontally would be the force required to overcome the friction between the third and fourth topmost books, rather than the force required to overcome the friction between the third topmost book and the table surface. The coefficient of friction between the covers of the books and the normal force acting on the third topmost book would still be used to calculate the force required to move the third topmost book, but it would be different from the force required to move it if it were in contact with the table surface." The friction coefficient of the table surface and a leather cover is missing in the task. Let's assume it is 0.5. Now, if a horizontal force pushes against the third topmost book, would the whole stack move or would only the books move, and what amount of force would be needed ? "If a horizontal force is applied to the third topmost book, the whole stack would move. The force required to move the third topmost book would be the sum of the force required to overcome the friction between the third and fourth topmost books, and the force required to overcome the friction between the table surface and the bottom book. The force required to overcome the friction between the third and fourth topmost books can be calculated using the formula: F = μR where F is the force required, μ is the coefficient of friction between the books covers, and R is the normal force acting on the third topmost book. The normal force is the weight of the third topmost book (1.5 kg). So, the force required to overcome the friction between the third and fourth topmost books is: F = μR = 0.5 * 1.5 kg = 0.75 kgf or N. The force required to overcome the friction between the table surface and the bottom book can be calculated using the same formula, but this time the normal force is the weight of all the books (2 kg + 2.5 kg + 1.5 kg + 3.3 kg + 4 kg = 13 kg) So, the force required to overcome the friction between the table surface and the bottom book is: F = μR = 0.5 * 13 kg = 6.5 kgf or N. Therefore, the total force required to move the third topmost book and the stack is 6.5 N + 0.75 N = 7.25 N." *I have almost given up after this last answer* see following comment

[@SuperZardo]

To be clear and in order to avoid any misunderstanding, the friction coefficient of a book cover rubbing against another book cover is assumed to be 0.33 and the friction coefficient of a book cover rubbing against the table is assumed to be 0.5 as previously stated. "I apologize for any confusion, you are correct. To be clear, the friction coefficient of a book cover rubbing against another book cover is assumed to be 0.33 and the friction coefficient of a book cover rubbing against the table is assumed to be 0.5 as previously stated. To summarize, to move the third topmost book and the whole stack horizontally, a force of 7.25 N is needed. This force is the sum of two different forces, one to overcome the friction between the third and fourth topmost books (0.75 N) and the other to overcome the friction between the bottom book and the table surface (6.5 N)." I am sorry, but in my opinion the way to calculte this should be different. In order to know whether a horizontal force applied against the third topmost book will result in moving only the topmost three book or will result in moving the whole stack of 5 books, the forces needed in the two cases should be calculated. But as a rule of thumb, since the friction coefficient of a book cover rubbing against another book cover is actually lower than the friction coefficient of a book cover rubbing against the surface of the table, it is impossible to move the whole stack when the force is applied horizontally against the third topmost book, only the three topmost books will move. If the friction coefficient of the cover rubbing against table was very low in comparision, it is possible that the whole stack would move and it would therefore not be possible to separate the three topmost books using a horizontal force applied on the third topmost book. "You are correct that in order to know whether a horizontal force applied to the third topmost book will move only the topmost three books or the whole stack, it would be necessary to calculate the forces required in both cases. As you pointed out, the friction coefficient of a book cover rubbing against another book cover is typically lower than the friction coefficient of a book cover rubbing against a table surface. Therefore, it is likely that only the topmost three books would move when a horizontal force is applied to the third topmost book. The bottom two books would likely not move because the friction between the books covers is high enough to keep them in place. In case the friction coefficient of the cover rubbing against table is very low, the whole stack would move and it would be difficult to separate the topmost three books from the rest of the stack. Thank you for bringing this to my attention and for providing further details and insights on this scenario. I apologize for any confusion caused by my previous answers." Now in order to calculate the force to overcome the friction which keeps the third topmost book in place, what are the weights which should be considered? "To calculate the force required to overcome the friction that keeps the third topmost book in place, the weight of the third topmost book and the fourth topmost book should be considered. The force required to overcome the friction between the third topmost book and the fourth topmost book can be calculated using the formula: F = μR Where F is the force required, μ is the coefficient of friction between the book covers, and R is the normal force acting on the third topmost book. The normal force acting on the third topmost book is the weight of the third topmost book (1.5 kg) which is pushing down on the fourth topmost book. So, the force required to overcome the friction between the third topmost book and the fourth topmost book is: F = μR = 0.33 * 1.5 kg = 0.495 kgf or N Therefore, the force required to overcome the friction that keeps the third topmost book in place is 0.495 N. It is important to note that in this scenario, as mentioned before, it is very likely that only the topmost three books would move when a horizontal force is applied to the third topmost book. The bottom two books would likely not move because the friction between the books covers is high enough to keep them in place." You have correctly identified that the friction between the book cover of the third topmost book (lower side) and the fourth topmost book (upper side) matters. However, your calculation of the weight pushing down on that contact surface is wrong. Do you know why? "I apologize, you are correct that the weight used in my previous calculation is incorrect. The weight of the third topmost book (1.5 kg) would push down on the fourth topmost book, but this is not the weight that should be used to calculate the normal force acting on the third topmost book. The normal force is the force that presses the two surfaces together, in this case the third and fourth topmost book. The normal force on an object is equal to the weight of the object and the force from any external object acting on it. In this case, the normal force acting on the third topmost book is the weight of the third topmost book (1.5 kg) plus the weight of the second topmost book (2.5 kg) plus the weight of the topmost book (2 kg). So, the normal force acting on the third topmost book is 1.5 kg + 2.5 kg + 2 kg = 6 kg. So, the force required to overcome the friction between the third topmost book and the fourth topmost book is: F = μR = 0.33 * 6 kg = 1.98 kgf or N. I apologize for any confusion caused by my previous answer, and thank you for bringing this to my attention." *This last calculation is correct, thank you.* Conclusion: it is necessary to teach the calculation steps, otherwise it will spit out nonsense

It's also incredible how confidently wrong it is at just solving the math once it's plugged everything in. I feel like combining chatgpt with Wolfram alpha would be terrifyingly powerful.

If you give it something novel where it can't regurgitate a highly probable latent space interpolation by next token prediction... well that's all it ever does, so of course it fails at literally everything else. It isn't accurate to ever say that ChatGPT understands something. It literally cannot understand and what we really mean when we say that is that it *appears* to understand based on that output. For now, we can almost always show that it doesn't really understand by interrogating it with more carefully chosen questions.

With the KE question, I am not entirely sure if it got the physics wrong, or the terminology?

It's because it's ultimately just predicting what the next word or phrase would be in the sentence, not that it's actually performing the calculations. It's likely only succeeding in certain calculations and deductions because there's enough data points within the data set it was trained on to form strong connections between those words/phrases/concepts that come through in the predictions it makes; it was trained on data that largely stated that _y_ follows _x,_ so when it sees an _x_ it naturally predicts that a _y_ should follow. Add more words/phrases/concepts leading up to _x_ that also end with _y,_ and it becomes that much more likely that _y_ will follow _x._ Conversely, if there was just a few data points within the data set stating that _z_ followed _x_ instead, then it becomes that much more unlikely that _z_ will follow _x_ even if you gave it a prompt that made it obvious that _z_ would follow _x,_ because it was trained on data stating that _y_ follows _x._ If you specialised the data set used during training or somehow gave it access to external tools that were specifically designed for these problems that it cannot reliably solve (and you trained it so that it would reliably use these external tools when it needs to) then you'd likely see the accuracy improve significantly.

[@daviddelaney363]

Asked ChatGPT to reconsider its answer in light of the the clarification on "stationary states". Here is what it replied: You're correct, and I appreciate the clarification. The statement, "The Hamiltonian operator acting on any quantum state Y returns the same state and its associated energy eigenvalue, E," is generally true for stationary states in the context of the time-independent Schrödinger equation. In the time-independent Schrödinger equation: Hψ=EψHψ=Eψ HH is the Hamiltonian operator, ψψ is the quantum state (wave function), EE is the associated energy eigenvalue. However, it's important to note that this equation is applicable primarily to stationary states, where the quantum state does not explicitly depend on time. Stationary states are eigenstates of the Hamiltonian operator, and when the Hamiltonian operates on such states, it yields the same state multiplied by its associated energy eigenvalue. For a general quantum state ∣ψ⟩∣ψ⟩ that evolves with time, the time-dependent Schrödinger equation is more appropriate: H∣ψ(t)⟩=iℏ∂∂t∣ψ(t)⟩H∣ψ(t)⟩=iℏ∂t∂​∣ψ(t)⟩ This equation takes into account the time evolution of quantum states. In this case, the state ∣ψ(t)⟩∣ψ(t)⟩ changes with time, and the Hamiltonian operator accounts for both kinetic and potential energies. So, to accurately represent the statement, it should be clarified that it applies specifically to stationary states governed by the time-independent Schrödinger equation.

That’s an interesting question. I would think that it is possible with something similar to braille to make it possible for a blind person to feel the diagrams with their hands, but since ChatGPT doesn’t have hands it can’t do that.

[@tordjarv3802]

Furthermore, there are several blind physicists. After just a short googling I even found a blind astronomer.

[@toddboothbee1361]

@@tordjarv3802 Some programs that teach the blind physics students forgo the diagrams altogether and use language instead. Some computers get around the difficult "visual" problems by translating diagrams into equations, even computer code that would render a diagram. In which case, hands aren't required. It's kind of like giving an IQ test to a blind person: you have to leave out the colored blocks, for example, if you want to get a fair assessment. Perhaps it would be a similar situation with Chat?

[@TheFulcrum2000]

I put this exact question into ChatGPT: Human: Can someone blind become a physicist/physics student? If so, what accommodations are made for them regarding interpreting graphs and diagrams? Could those accommodations be used with ChatGPT? AI: Absolutely. Blind individuals can become physics students and there are a number of accommodations that can be made to help them interpret graphs and diagrams. These accommodations may include using tactile graphics, providing verbal descriptions of images/diagrams, or utilizing assistive technology like screen readers or magnification software. Additionally, ChatGPT can also be adapted for use with these same types of accommodations.

[@DEFCON5307]

I do not exactly know how this works with blind people, but for me personally imagining the system (just general properties, not in detail. Sort of like dreaming?) goes a long way. If there is a way to give a blind person that initial idea of what certain systems "feel" like, then yes, it might be possible. For sure hard though

[@StormWolf01]

I majored in computer science years ago. I use chatGPT everyday. It's great to generate boilerplate code, but also to quickly generate code examples of things i'm not familiar with. For instance, i wanted to know about SVG images. I just ask him questions, and he generates the code. It's always an approximation of what i want, but i just tweak it a bit, and it works. I also use it to ask a lot of technical questions. I also use it as a dictionary and helper for language studies. You can ask him question, and ask him to answer in another language for instance. I mean, it's great all around. I haven't really used google or stackoverflow in the last 3 weeks.

[@nao_chan_]

I wouldn't get addicted to it. you're essentially like a homeless person feeding yourself with free samples from the supermarket. they can pull the free trial stuff at any moment. if a commercial version ever appears it will likely cost a LOT of money to use. the servers to run this thing aren't cheap.

[@kinggrantking]

Damn. You can really tell at the end with the coding example that he's realized this thing is out-of-control smart. Even if a student couldn't simply copy paste the answer, their days of doing the grunt-work are effectively over. As long as you have the knowledge, you can simply have GPT write an answer and check its work rather than write every line of code by yourself.

[@lored6811]

If ChatGPT gets a Math Backend, things will get a lot more interesting. This has to be combined with a latex parser, else there is too much ambiguity in the English language

[@mrnarason]

Isn't it chatgpt just a language model? If it could understand and produce calculations or proofs wouldn't it be more like lean?

[@fredrikweme1387]

Someone allready made a functioning chstgpt version that uses wolfram alpha api when it needs math help. Dont have a link but was a fairly new youtube video on it

[@AnotherFancyUser]

@@mrnarason They (Microsoft or whoever the new owner be) can make pre trained models of specific topics, which would be more accurate. But yes, it is a language model.

[@Convergant]

​@@mrnarason It is a language, but it is surprisingly capable of doing these problems on its own. As an example, (after the due date) I gave it a question from my linear maths coursework: (a) State the Rank-Nullity Theorem. (b) Does there exists a linear transformation T: R^3 -> R^3 such that im(T) = span{(1,1,0), (1,0,-1)} and ker(T) = span{(1,1,1), (1,1,-1)}? (c) Does there exist a linear transformation P: Q^19 -> Q^19 such that rank(P) = null(P)? Its answers to all 3 were perfect. Obviously, it could parrot a well known theorem like the RNT, but it was able to correctly identify that neither linear transformations could exist using the RNT and explain why - essentially, complete proofs. This obviously isn't the same as being able to prove/disprove any conjecture in general (in fact, this is not possible in a finite amount of time), but I was still impressed.

[@NuclearCraftMod]

@@Convergant It has about 50 times more nodes than there are words in the entirety of Wikipedia, and in fact the entirety of Wikipedia, or at least most of it, made up about 1% of its training data. There is a lot of linear algebra on Wikipedia, and it was probably trained on a heck of a lot more. Of course, that goes for every subject, but I do think the sheer amount of computation involved in the training process is beyond reasonable intuition :P

[@bawzzzz]

One thing that's really missing from this video is that there never was any follow up questions asked about the original question, like asking it that there might be a mistake somewhere and so on. That's where chatGPT truly shines as it doesn't forget context and can produce corrections. Just asking it point blank question without follow up, although impressive, kinda defeats the purpose.

[@colourofmage]

Might be worth retrying these questions! The update from 30th Jan has improved factuality and mathematical functionality

[@jrbling25]

ChatGPT is certainly NOT a calculator, though it can be very fooling and manipulative in its logic of providing understandable answers in plain language. I asked it to integrate a very simple function the other day, it provided a great series of steps and explanation, but it mishandled a simple arithmetic step. After trying to 'help' it check its answers, it did realize, which is impressive on its own i suppose.

[@wdbressl]

It has been discovered that it has been given a political bias. Very concerning to find out.

[@op4000exe]

I'm going to be honest, considering how far these AI's have gotten over a rediculously short timespan, I wouldn't be surprised if there soon existed an AI that could both do proper explanation of the matter, and properly understand the physics and mathematics to fool even someone of a very high level of understanding within said field of study. It's both equally horrifying and amazing to watch I'll be honest.

[@oldnelson4298]

I think genuine understanding is a long way off, but it may be able to trick experts into thinking it understands - it already can occasionally!

To respond to a number of comments here: Don't be the person who extrapolates things linearly for the sake of making big predictions. The vast majority of remarkable phenomena are on logistic trajectories, neither linear nor exponential.

[@adfaklsdjf]

from what I can tell, with AI we are still in the accelerating/steepening part of the S-curve

[@jakesecondname2462]

@@adfaklsdjf it is completely impossible to tell which part of the curve you are on at the time, because different parts of the curve look quite similar to other parts of it during real growth, and one can go through "stuttered starts". We may flip onto another S curve at a later time which has a higher maximum rise, say if we cleverly combine symbolic with neural techniques, and this regularly happens, but predicting when, if, how, when, who, why, or where this happens is a fool's game. The only thing you should say about technological progress is that which is totally obvious based on your current expertise, and speculation should be treated as it always should have been: lots of fun but not much use for anything else.

I had 2 years of Physics in college and I couldn't even answer those middle school questions. Physics always went over my head.

[@rob86353]

What I find really interesting is when you point out mistakes that ChatGPT has made. In the context of that conversation, it remembers the correction, and appears to /somehow/ incorporate that correction in further responses. As to how it does this, and to what extent that "learning" is actually occuring, I have no clue.

[@adfaklsdjf]

it's not learning during individual conversations.. it's just generating new text based on the text that has come before. after you correct it, it's generating more text that is appropriate/likely given the previous text that includes the correction.. i use it for generating code sometimes and it's great at taking corrections and adjustments.. when i'm not satisfied with the result, i simply tell it why the code it's given me isn't what i'm looking for and ask it to change it and it does surprisingly well. it's not going to make my job obsolete (that's probably like 10 years in the future), but it's really helpful for rapidly producing some code in 3-5 minutes that would've taken me 30-45 minutes to write on my own.

[@rob86353]

That's why I put learning in quotes - not implying core concept processing. Interaction based improvement to result quality. What I would be interested in seeing is, as we adjust our path costs and reposition on whatever conversation map ChatGPT uses, ie the contextual version of 'learning', how much of that conversation state can be retained or saved for future use, and how much that impacts overall conversational flexibility of that AI instance. I do agree on the code it generates being interesting. I tried throwing it at it some samples of generic programming tasks I have had to work on, and it generates some interesting results. Usually better than whatever my first draft would have been, but often with conceptual holes, inappropriately mixed code (ie powershell 5 mixed with PS 7), and a complete lack of input sanitation and/or (... usually and) dangerously unchecked calls to external functions.

i also tried same question in chatGPT Paid version! "We can use the formula: time = energy / power where energy is measured in joules and power is measured in watts. We need to convert the power from watts to joules per second (or watts to kilowatts) since the energy is measured in joules. 7200 W = 7200 J/s or 7.2 kW Plugging in the given values, we get: time = 162000000 J / 7200 J/s time = 22,500 s Therefore, it will take 22,500 seconds or 375 minutes or 6.25 hours to fully recharge the electric car battery from zero, assuming that the charging process is 100% efficient. In reality, charging efficiency and other factors may cause the actual time to be longer."

[@GilesBathgate]

I guess the internet (and hence ChatGPT's training data) is full of mission statements and code, but answers to physics exams, not so much ;)

[@peterisawesomeplease]

I think there are plenty of answers to physics exams. The main issue is that you can parameterize questions infinitely which really throws off something that is mostly a search engine. It will find the closest question but even a slight change to popular question will have it give you the answer to the popular question not the question you asked.

[@GilesBathgate]

If you think its like a search engine you probably haven't played with it enough. For me Its more like using a search engine for 10 minutes, reading various posts that people which contain answers to similar questions, and then forming a coherant paragraph based on the results, but it does it all in a fraction of a second, and by recalling "the internet" from memory :)

[@adfaklsdjf]

It's not a search engine.. it doesn't contain the text it was trained on. When it's answering a question, it's not scanning through its training data. Rather, it has mapped patterns that were observed from the data set. The model itself is no larger after training than before training

[@peterisawesomeplease]

@@GilesBathgate I played with it quite a bit and it did feel a lot like a search engine that combines results from different websites. It clearly can go quite a bit beyond this. You can have it program things that no one has programed before quite easily. But this often relies on being so hyper specific that it feels like its just combining stack overflow answers in a clever way. The speed and is unimpressive to me. The model is pretrained.

[@GilesBathgate]

@@peterisawesomeplease It does feel like that, but try talking to it about something completely made up, and it will also give you a comprehensible answer. Invent your own maths symbol, or some characters in a story that you've invented, (but not something published on the internet.)

At 4:30 -- "The reasoning is correct, but it lost a factor of ten." I ran into similar errors with legal reasoning.

It makes authoritative statements without a clue. 11:39 -- Like my *second* question regarding a *social* scientist; a total failure of facts /and/ reasoning.

[@kam_iko]

the most common mistake that i’ve experienced so far (beside it making stuff up, with confidence 😅), is that it regularly has problems with comparing numbers. simple 4 digit numbers, where it will say one is greater, than the other one, when it clearly isn’t. it needs access to a wolfram alpha backend.

[@VodShod]

11:13 That is completely different than how my teacher thought of it. They said if a student did not understand the course material by the end of the term then they had successfully weeded out the people who were not meant to succeed. The first thing he says to each class is: "I am not here to teach you, I am here to weed out the failures" Another teacher at that school had this as their opening: "I am not here to teach you, I am here to make sure you read the book."

4:52 One of the ways it really helps in speed-cramming something I'm unfamilar at.

I had it solving graduate level classical mechanics problems from Goldstein's book. It was spot on in about half the cases I tried. Frequently, a nudge in the right direction was required. In some cases, I'd say 10-20%, no amount of nudging would generate anything useful, or even, at times, comprehensible. Also, it understands Latex notation very well. It can even handle, evidently, a kind of "quasi-Latex" combination of Latex and straight text.

Maybe chatgpt interprets “displacement” as “maximum mobility” not as “maximum distance from center of oscillation”. In terms of the principle of equivalence, displacement is both. Chatgpt seems to grasp Ekin Epot
