It's also hard when you're looking for a gf or wife, and all that flocks to you are "the darkly inclined." Some women ruin everything (just the "pretty" goth ones). It shouldn't be about complete and total fiction (i.e. Frankenstein, mad scientists). It should be about the real world. I am SLOWLY getting back my interests, thanks to a co-worker, and my brother.

[@the11thken]

This is probably true my teacher don't care about us students

[@mrnasty02106]

@@the11thken That's another reason. In order to make any subject learnable, you need a teacher that cares about students. Not one that loves to be dictator (yells, writes anyone up), not monotonous, and not scary. What I've been all along is: it's not the subject itself, it's the people. That's true for anything. I love chemistry, biology, and physics. It's the instructors, teachers, classmates, peers, etc. that make or break interest.

Back in 2018 I stopped everything I was doing and just sat down to study and master basic arithmetic and algebra for months. Saved my life. Before I had trouble converting between say decimals and percentages, or dealing with some more involved equations with lots of fractions, powers, and so on. Had trouble with graphing too. I just practiced everything as much as I can, mixing the different skills, testing every scenario, using tools like desmos and geogebra to help me experiment with the concepts. Eventually this made algebra a trivially easy thing to do. Best thing I've done in my life tbh, since a lot of my interests are math based.

[@albirtarsha5370]

I have seen many students who did not care. What made you care enough to really apply yourself?

[@AriaHarmony]

@@albirtarsha5370 my main motivation is that my interest are really math heavy (astrophysics and machine learning), I told myself if I keep struggling with fractions I won't be able to deal with physics any time soon 😅 so I had to conquer it. If you're a physics teacher you can remind your students of their goals, even if the goal is just to graduate with high grades, and especially if their pursuits involve math, remind them it's always worth it to master the fundamentals, it's a one-and-done thing that will always serve you, better to struggle with just the physics concepts than to struggle with both the physics AND the algebra right? That was my logic 😅 But unfortunately I only did this as an adult after leaving school. During school I just didn't have the time to do this even tho I had the interest, I collected my math textbooks since like 5th grade and always had the plan to set down and really put together everything I have studied and master everything. But unfortunately I just never found the time as a student in K-12. And now since I can't afford higher education I just continue teaching myself my favourite subjects with plenty of time to invest in them.

I got more out of it than those I was teaching. Coolest thing: The guy who was struggling, but actually kept showing up, and got better and better. He never tried to "just get the answer".

The basics is exactly what's in the video, algebra. Just get really good at manipulating equations, everything will make much more sense if you can follow the derivations. You might also start learning polar form vs Cartesian form, how to convert between the two (that's basically vectors). Knowing integrals is useful for understanding derivative, essential if taking a highly rigorous physics course (major specific intro and above). But yeah, basics=algebra

[@Kaldunaa]

I know Calculus well but for me it's harder to get to the maths part than actually do the maths. So understanding the problem and applying physics to it is where I struggle the most.

[@domkhoury3149]

that’s exactly the hardest thing about physics. the math (most of the time) isn’t the obstacle

[@imafackinjunglist]

A thermometer has a measurement system. Before there was one, there wasn’t one. Physics is like trying to tell a temperature with out the measurement system on the thermometer. Every new physics calculation is adding another measurement system akin to the one you can find on a thermometer or a ruler; or a calculation that brings math into proportion with a previously known measurement system. Wave function is one, spin quantum number is one, E=MC2 is one, Cm & Meters is one. Yada yada. Once you understand what they mean and where they apply in terms of scale you understand the system. You do not need maths to do this. You need maths to discover/prove it but it doesn’t mean to say you need maths to go in the direction of discovering something new. For example, I don’t understand the maths behind thermodynamics but I understand thermodynamics enough to help not crack my windscreen when it’s frosted over. I can use this as an analogy to describe phenomena at a molecular level but it doesn’t mean to say I could write it down in an equation. I think we have the same problem. 😂

[@Fractured_Scholar]

@Kaldunaa - What do you think limits your understanding of the problems?

[@nikoszervo]

This is normal and it doesn't have to do with your understanding in physics. You're solving a problem, and THAT is the hard part. Even if your understanding of physics is really good and you have a great knowledge of math, it can still be really hard to solve problems that you have never encountered before. Just remember, that even the easiest problems in math, took many years to be solved even by great Mathematicians! And how can you become better at solving problems? Just by practicing and seeing as many solved problems as you can, it's the only way!

[@cryora]

Sometimes it's the math, sometimes it's the physics. People sometimes get caught up in the whole idea that physics is physics and not math, that they end up using poor and oversimplified mathematical models for situations that require more sophistication. Spherical cows is a common physics joke. That's where you have to give engineers respect, because they are actually the ones to do detailed fluid and finite element simulations using programs like COMSOL or ANSYS to really analyze the details. Why physicists don't do this is beyond me. It's the same way it is baffling that chemists aren't the ones studying elementary particles but rather physicists are.

[@hooh5479]

Hi, thank you for this analysis. Physics is hard for many students not only because of gaps in their knowledge in maths or because of lack of practice, but also and probably mostly because developing a clear and proper representation (or mental picture) of the problem at hand is not as easy at it seems. As a teacher of physics, I see that a rather large proportion of students in a cohort find it difficult to develop their reasoning. Proper reasoning requires a good knowledge of the notions discussed during the lecture but also an ability to picture mentally the studied problem. This is particularly true for thermodynamics when a key step for problem solving is establishing the correct energy balance.

[@Prof-Hafner]

Yep, there are lots of reasons physics is hard! Visualizing in 3D can also be tricky (related to your point). I am bad at that. I can do it, but I have to really stop and take a minute.

[@emar22111]

This might explain why I’m excellent at maths but terrible at physics

[@hooh5479]

@@emar22111 Same for me! Though I wanted to become a physicist, I always was better at mathematics. I started uni in a maths program, always keeping in mind a transfer to a physics program at some point, which I did in third year as I felt more confident that I could at least manage the formalism of quantum mechanics, kinetic theory, mechanics, etc. However, it proved extremely difficult for me to adapt to the physics curriculum: the way they do maths in physics is not rigorous and I got frustrated, and my vision of physical systems was always blurred. It took me years, up to PhD level, to adapt and change my habits to become a physicist. Still, I find it easier to teach the mathematical formalism than to teach how to mentally picture physical systems and processes; cognition is something quite personal and there is no recipe that works for all.

[@catherinemarsh5453]

The best way to learn physics is to have 1000 questions from the simplest, gradually getting more difficult. Memorise your formula for each topic. Practice writing out or telling someone else your understanding of the concepts of each topic. My physics professor always had the whole blackboard full of questions and our lesson was doing each one and he would also talk about the concepts as we went. I remember after attending my first lecture with him, I was so excited to go home and do the assignment for the week. Who gets excited about physics?

[@Prof-Hafner]

Yeah sometimes I worry we go straight to the "deep understanding" problems, when some folks need to start by doing routine problems to get used to the formulas and concepts.

[@greathoonta3461]

Physics is hard because it takes experience and practice to learn everything. You can’t simply walk in and be really good at it, you need a good teacher. The issue is way too many physics teachers either won’t give you the time of day, or they are just so busy they can’t give everyone enough time.

[@anthonyclarke5579]

I was a lost cause at math. The deputy headmaster (Ernie Enderby) gave up his lunch hour to educate me one on one, with no distractions. X & Y meant nothing to me, so Mr Enderby brought in a bag of apples and oranges and used those in place of X & Y so that I could follow, see and visualize the equation. I failed the exam. I did sit a retake six months later, I passed with the lowest grade. Other subjects I passed easily never gave me the happiness of my math pass, it still pleases me to this day. I should have gone back to the school to thank Ernie Enderby but I was still young in1973 and had my head up my arse. Thank you Ernie Enderby for giving me your time and effort.

It's wonderful to hear that Mr. Enderby went the extra mile to help you understand math and that you eventually passed the exam.

0:05 is the most accurate description of a Physics Student

[@MarkoBotsaris]

As an ex-physics professor I know the answer to this question. I’d like to say my college teaching experience is why I know the answer, but honestly my years of helping and attempting to help my “pre-med” or “other” friends and acquaintances deal with their first physics and calculus courses already taught me where the essence of the difficulty lies for some people. The answer is that Physics, and also Calculus, are very often the first place where a whole LOT of students come up hard against the requirement to turn actual understanding and first principles, rather than rote memorization, into practice. It is the first place in our present educational pathways that many students come up against the a brick wall that is very hard to penetrate with rote learning. Yes, students are exposed to baby versions of this kind of “thinking on your feet” much earlier, like proving theorems in geometry. And they can fake their way though an imitation of the process in algebra and pre-calculus by memorizing and implementing a small set of rules which they are then taught to apply by rote. But the rubber really hits the road in Physics, Calculus, and especially in the required pre-med “Physics with Calculus” - the horror, the horror! For many students the memorization-heavy, analytical-thinking-minimal method they have used with great success up to then fails at this crucial juncture. “Fails” is perhaps too strong a word since absolute failure would probably have been a gift at this point. In reality it is more cruel that that - the memorization it takes to avoid fundamental understanding, the FAR easier alternative, ramps up exponentially until it reaches an absurd level forcing a crisis in people that haven’t yet had to face such things previously. An (over) simple example - the absurdity of trying to memorize the “formulas” (x = g(t), v = h(t) ) for every trivial mechanical question involving Newton’s laws rather than learning how to apply them ab initio. Anyway, many of the students that are freaking out at this point are experiencing the failure not of their intelligence, but their highly developed, and by this point time-tested and proven memorization-heavy “learning” (and it is not an exaggeration to call this UNDERSTANDING) techniques. This problem is something very hard - leaving aside that teaching students HOW to think is not really in the job description - for the professor to simply “teach” the student out of. I know from experience the disconnect when a student that wants “help” but is only prepared to accept it in the form of an answer to “tell me which formula I should memorize?” The frameworks for exchange of information themselves are mismatches - or aptly, “the matrix is something one cannot simply be told about, you have to experience it for yourself”. 😂 For a few or the students, the ones that are already prepared, this is a point they experience as a kind of liberation. For the others, especially some of the pre-meds that are “forced” to endure this trial - coming in to the class with an “I’m gonna hate this, but I have to pass and hopefully get an “A” to get into med school” really doesn’t help - it can seem like nothing makes sense anymore. To have this occur at a time when nearly all of these students are also experiencing a new environment, and new social pressures, well that is a recipe for trouble!

In my junior year of Chemical Engineering I tutored a older nursing student in organic chemistry including some reactions. She was going into nursing from a clinical psych background. When she was able to visualize in 3D and notice things like where a slight charge would be she finally turned the corner. She no longer needed the models. She finally understood why there was more than one product of a reaction and what the probable ratios were. That slight charge thing, that was a tough one to get her to. She understood an electron has a charge, and that is the unit of charge, so how can a compound be slightly charged at different places. It was a victory for both of us and one of my greatest achievements.

I think it comes down to learning preference. In high school, typically the people who take biology (lots of memorising) don't take physics (very conceptual and math heavy), and vice versa.

Going deeper however, to be successful in any rigorous academic pursuit, developing critical thinking skills are an absolute necessity. It’s the basis for all logic and math.

We tend to believe we are more rational than we really are, so our expectations that maths should be easier to learn than they actually are are usually wrong.

I've always been pretty good at math. When I took relativistic physics I got a reality check on how theoretical I was capable of thinking. Just meet with your physics prof during office hours and send some emails back and forth. The more he/she sees you are trying the more likely (he) will be to help you understand the concepts that he will be testing you on directly. I failed the first test (30% of our grade) and panicked but utilized every office hour session available to study directly with my prof. I ended up acing the midterm (30% of our grade) and think I got a B+ on the final (40% of grade). Ended up passing the class even though I wasn't happy with my overall grade.

Yup! I also think that approximations trip up students sometimes. Trained physicists have a good eye for the essential features of a problem and can drop some of the details to approximate. Students can sometimes find all the information overwhelming and not know where to start.

[@martymcfly1776]

They don't learn approximations in high school. In some cases such as the small-angle approximation in the motion of a pendulum, it is the approximation that makes it possible to solve. I would make the students put their calculators in radian mode, and then have them calculate the sine of .001, .01, and .1. The real logic or the small angle approximation comes from the Taylor-series expansion, but a simple practical demonstration is probably more helpful.

[@ruslb818]

I teach both physics and calculus and I agree with you 100%. Math is so important. However, I had students who had all A's in math, but did not do well in physics. They just couldn't grasp certain concepts. I think the reason is that in physics no two problems are the same, you can't just memorize some steps on how to solve a problem. In math, including calculus, many procedures, like the product rule, can be memorized without even knowing the proof of the formula using limits. In physics, you can't just memorize that the net force is mass times acceleration. For a simple example, like the Atwood machine, students need to be able to draw a free body diagram and to add all the forces and then solve for acceleration by using algebraic methods like substitution or elimination. That requires a skill and critical thinking.

[@martymcfly1776]

I taught Engineering Mechanics to first year Engineering students, and that's like physics on steroids. An elementary issue of course is understanding vectors and how to do calculations with them. Another issue, which is why engineers emphasize Free Body Diagrams is understanding the point of application of the force. I find that it can be difficult to convince students that they need to use vectors, but it's even harder to convince them that the point of application of the force is important. It's all kind of detail-based and pedantic, and people don't embrace that. They want it to be easy.

I think students think physics is hard because we wait until 10th or 11th grade to teach them what we'd like them to know when they graduate high school. If we started teaching physics in 6th grade, and taught them some each year, they wouldn't think it was so hard. We teach kids "English" and "history" each year until they graduate, but we expect them to absorb all of physics in one class in one year.

I think many in calculus courses still suffer understanding the algebra, and those in algebra have a hard time doing basic math. This is as courses usually just need a C- to really move forward and those exams are always curved where you might only get 3/10 questions correct and yet "pass". So the student is unprepared to deal with calculus-based physics where the teacher is usually unlikely or not fond of teaching you the underlying math.

I'm currently doing my masters in mathematics. In order to truly grasp certain proofs and concepts, I've been making use of memorization and high-level learning. My point being that those two have a role to play even in the technical disciplines! Since math is necessarily very detailed, it's easy to get lost. One might have understood every detail of a proof, but done so at the expense of the bigger picture. Recently, I've been trying to approach proofs in a two-fold way. First, I study them at a high level, and try to understand the main ideas. Then, on my second or even third reading, I worry about the details.

[@Axel_Andersen]

Right, I've often wonder if the approach of teaching (and even going through) proof is a good way to teach/learn. Yeah, you learn (hopefully!) how to proof something or derive something from first principles but you may lose the point why something is useful and even forget (by the time you are through) that there is this or that method (don't know the correct English word) that you could apply in this or that case. In my youth (before computers) complex arithmetic was used to solve certain electrical circuit (AC) problems. I often complained that I've never seen or heard of a complex or imaginary electricity/electron/current so why do I have these in the equations. Took me years to realise that it is (well, today, it was) a handy MATH tool to deal with sinusoidal signals.

For example, cases of systems of pulleys where there are horizontal blocks affecting the motion of a falling block, or cases where a man would be in a self-lifting elevator - they troubled me a lot when I solved in conventional ways.

Physics is hard because sometimes because of following reasons. 1 I for example don't have background in topology or conformal geometry, so if you start writing such equations in string theory I won't know where to look , which book to learn from . So it would be nice to put an appendix and explain all equations used say of conformal geometry. Another example if you start talking about so3 groups or Su groups I won't understand what these mean. So I suggest make it more transparent. Make a 600 page book rather than a 250 page book. This is why Physics made hard actually it is almost high school if you know the mathematical steps. The real hard part is application. Sometimes I read a chapter in Quantum Mechanic's say entanglement I ask what are the real implications of it. Now being an Engineer by profession I see entanglement as a very powerful thing. But you guys are caught in ideas like superposition states. So for example what is entanglement say in a black hole. Does entanglement contradict Uncertainty. You know you guys are killing oeoples interest in a subject. Reminds me of a Professor teaching me flow around a cylinder. He never mentioned what it really meant, I only realized after I worked on unsteady flow problems around external fuel tanks for large commercial planes at Boeing. Please I suggest to all of you smart people out there, dont cloud the subject, clear the subject. I for one wanted to develop higher than light speed travel.

Calculus is harder than algebra (introducing the dx is another level of change). And now physics takes the real world into the already abstract world of mathematics. The more levels of abstraction, the greater the percentage of the population that will struggle to understand.

I find "pure maths" easier than physics because physics has several constraints - it has to apply to the real world. In math you can draft theorems and lovely conjectures for days; in physics, experiment is king and the marriage between spatial reasoning, numerical reasoning, and verbal reasoning intersects.

What is difficult is the mathematics: Riemann's Geometry. This is 99.9% of GR. Riemann himself would probably understand Einsteins theory with a glance. But if you don't understand Riemann's Geometry, you will never understand GR. Just some handwaving arguments, but not the deep geometric meaning of he theory and where all these seemingly complicated factors in the Einstein equation come from. So Einsteins main achievement was to understand the mathematics of Riemann's Geometry and apply it to a simple physical problem. That was the tough part, but not the physics itself, which is almost trivial.

Physics is definitely not impossible without Calculus knowledge. Calculus definitely adds more context in how you get the formulas for the calculations but my high school physics class was pretty much all algebra based. What also trips a lot of people up is dealing with frames of reference. People get tripped up when it comes to how you establish your coordinates but it really doesn’t matter as long as you are consistent. If you say that (in the case of the x-y plane) that x is positive if moving to the right and y is positive going up you could totally change it if you want as long as you apply that to everything else in the system. This also applies to things like conservation of force and momentum where a force can be considered positive if it’s acting in one direction and another can be negative if it’s acting in the opposite direction. Those concepts always seemed to trip people up who were just taking introductory physics courses. Conceptually physics is not that hard even if you’re not great at math. If you’re not strong in math you will have a hard time with the calculations but the ideas like Newtons laws are not hard to understand.

Hi, i just want to add something. I've applied for university physics which turned out to be one of the worst decisions of my life. The reason i applied for it was my ambition to get into the research field in something like nuclear physics and maybe tackle real-world issues. I did fairly well in college and got accepted into university. To be honest, i didn't really know what to expect maybe it would be a fun experience. As it turned out i was constantly struggling. Whenever i practise questions or do the assessments, i end up getting a completely different answer. Most of the questions were deceivingly difficult. They look easy at face value but the solutions were complicated. I didn't know why i was struggling when everyone else was doing fine. The biggest differences i notice between university and college physics were: 1. Memorising equations isn't going to get you far, you pretty much required to understand them. 2. There were A LOT more calculus than i imagined there to be 3. You are way more restricted to getting help from lecturers, tutors and other staff so you can only depend on other students 4. Problems solving skills or analytical skills are just as essential as mathematics skills and they're arguably impossible to practise independently When it came to trying to understand the physics of something, i thought that was easy to do. however, it was trying to translate that to the appropriate mathematics. I was decent at maths but deciding what maths to use is where i ALWAYS fall flat on my face. Whenever i try to contact my personal tutor or lecturer about my struggle with a question i never seen before, it's usually "no no I can't help you. you need to figure it out yourself." or they'll forward it to someone else and end up reiterating what i've already learned. Getting help from other students was also a struggle in itself. Long story short, i couldn't get along with the physics students and I didn't particularly like them. As a result i was mostly on my own. The only thing i was at least decent at was the lab experiments and get along with one student who was also good at it. I preferred more practical work. Programming was another big part of the course i disliked just as much as the theory work. This sense of struggle and isolation resulted in one of the low points of my life. After semester 1 i thought to myself 'maybe it'll be better' and I REALLY wanted to like physics but ended up getting a lot worse in semester 2. Eventually I had to own up to my personal tutor and literally say 'I'm not enjoying the subject'. He came up with a few suggestions. One of the suggestions was to retake the first year (...yeah fuck that). Another was change subject which i ended up doing. I chose to do electrical engineering the next year which turned out to be a much better experience and got along with everyone a lot better. I wish i knew earlier what university physics was going to be like. From what I've learned in doing physics is that it's not 'why is physics hard?' it's more like 'is physics enjoyable?' apologies for the long comment. I felt i had to get it off my chest

Hi - sorry you got off to a rough start but I'm glad things are better! Anyone is free to vent here. :)

Very interesting

I think another significant source of difficulty in studying physics is that sometimes the concepts may be difficult to grasp due to how they defy out natural intuition. We carry assumptions about how the natural world works based on our own personal perceptual experience with nature and wind up forming assumptions about the workings of nature that turn out to be wrong. In the practice of natural philosophy, before the advent of the scientific method, philosophers were frequently wrong about their conclusions about the workings of the natural world when they tried to understand it with reasoning about their own experiences. Once the scientific method was developed, it provided a way for us to ultimately realize that often times, things appear to work a certain way only because of certain conditions being present and if the conditions were different, then the outcome would be different in ways that could be quite unexpected due to how they contrast with our common experience. A common example of this discrepancy is when students learn about the fact that objects fall at the same rate (when air resistance is not a factor). If a person were to drop a bowling ball and a piece of paper, they might expect from common experience that the bowling ball should fall faster. After all, it is much heavier and heavier objects just seem like they would fall faster. But if one crumples the paper so that it does not catch as much air in its freefall and air resistance has a much more negligible effect on the paper, suddenly the paper now appears to fall at roughly the same rate as the bowling ball, despite being much lighter in weight!

Physics is hard for most people because there is a layer that is very much like the law. One has to memorize the definitions, word by word. They were worded in a certain way to reflect natural observations. Change the wording and the meaning misses to represent reality. On some level one has to think like a lawyer to be a scientist. Not everybody is good at that.

For me it was always about finding a way to represent the problem. The first week of physics was always about converting units from one to another, and it was strange to me why that only happened in physics class. Later in life, as I challenged myself to do some really complicated programming, I started to appreciate the skill of representing a problem in a way that allows it to be solved. But that doesn't mean I ever really got good at physics at all.

Physics is hard when the teacher make it boring.

[@ackinito]

Physics is hard because students are not exposed to challenging problems in high school and thus do not develop the necessary problem-solving skills and critical thanking. Compouning the difficulty of the Physics subject with the math requirement yields the results we observe today.

The physics of pointing the camera at an angle where viewers can see something else other than something that everybody else has would great.
