[@devpoodle]

⁠@@bealu9459despite its name, linear algebra doesn’t have anything to do with graphing lines. it’s mainly about two things: vectors and matrices. Vectors are like a fancy way of storing coordinates. And matrices are a way of representing certain transformations you can do to those coordinates. linear algebra has a ton of fun applications, so I’d really recommend you learn more about it.

[@gwho]

this video actutally expaining what calculus, differentiation, integration IS and how it's basically slope and sum of curved functions is SO much clearer, less stressful, and is better for deeper understanding in a shorter amount of time than the confusing non-explanations in school class with stress homework, reading difficultly worded textbooks, spending so much time on an example that doesn't make sense to try to extract the core concept of calculus.

[@kevin_delaney]

I haven't watched this yet, I certainly look forward to any and all of the content you post. I thought I'd never use Calculus, or Trigonometry (which is kind of REALLY important in many areas of calculus, wish I discovered that sooner) in high school because none of my teachers really knew how to apply it outside of teaching, or at least few gave real-world examples if they did. I took an interest in additive manufacturing, electronics, and robotics. Computer Science in general interests me personally, so AI in general of course, but that tends to use more linear algebra in my own personal experience. In 3D printing and robotics, a common "tuning" algorithm is PID feedback loop. A Proportional-Integral-Derivative control loop is used to "tune" Servo motors (brushless AC and DC multi-pole, multi-phase motors, not the cheap DC three word RC 'servos') as well as heaters, fluid pumps, fans, and a ridiculous amount of applications in many different industries. It is a relatively simple control algorithm that gets fantastic results after a few cycles and really improves efficiency and reduces error. Another use I've come across is how my 3D printer (running with a Duet 2 controller with dc42's fork of Reprapfirmware, an OSH and OSS project) auto calibrates itself using a "root mean square" algorithm after probing the print bed. Had I known how useful some of these concepts were in computer science and robotics, I would have paid MUCH better attention in high school. I was never exposed to it as a kid. Not only is your content educational and high-quality (as far as editing and scripting is concerned) but it is also [high-quality education]. Being 25 years old, I can assure you and anyone else that education, especially in America, is not always high-quality. That cannot go unnoticed, I find tremendous value in the content you post and only wish you uploaded content more frequently.

But really, our professors don't know how to teach maths. Thus, this channel is my inspiration.

[@kevin_delaney]

Sourav Goswami Have you ever heard of Khan Academy? The Domain of Science's channel is not so much about specifics, although he does indeed give some fantastic examples and simplifies it to an easy to understand, far less intimidating, and potentially enjoyable subject. For him to legitimately teach some of these subjects would require much longer videos. He seems well-educated enough, I am unsure if he will take it that far. I am working, so perhaps this video is more in-depth, I don't know. Nevertheless, EdX, MiT Open-Courseware, and specifically Khan Academy should be more than enough for you for now. Really look at Khan Academy, I cannot stress that enough. You could legitimately replace school with the amount of education that is in there.

[@agustinusbravy6459]

The Gaming Army Generally you use integration by parts when there's a product of two functions that are not all polynomials. For example ln(x)*sin(x). If you're confused just ask yourself "what is the derivative counterpart to this method of integration?" For example the integration by parts above is derived from the product rule, so it must involve multiplication that cannot be solved by other rules

Another job was in a gun propellant factory, I was the only physicist under a lot of chemists. The chemists new some of the physical laws but not the details. For instance, the combustion speeds of propellant is expressed as v = beta * p^alpha as physicist it is obvious that this is the differential equation for an exponential v proportional to dp/dt = beta * p^alpha, I wondered why do these guns not explode but then learned, that this was the art of judging the size of the propellant grains so that the bullet has enough time to start to move. As most of the exponents are integers or brocken integers and alpha was close to one, so I told the chemists to put it to one, in addition this gave a very, very simple linear expression to calculate the first approximation for the propellant dimensions involving only the velocity and weight of the bullet, both known very precisely. I later read in a defence book, that actually alpha is equal to one above pressures of around 300 bars compared to 3000 to 7000 bars of peak pressure, so it was a good approximation.

[@sutapasbhattacharya9471]

Did you know that Calculus was invented in India centuries before Newton - in fact, most of what the modern West called Modern Mathematics 500 years ago was Ancient Indian Maths. Arithmetic is the Indian Decimal Place-Value Number System with Zero - which Cambridge profesor John Barrow wrote is the greatest intellectual invention ever made by humans. When this Indian system reached medieval Italy [Leonardo of Pisa translated Al Khwarizmi's Arab translations of Indian works], people paid to watch mathematicians do calculations such as 27 x 14 in their heads at fairs - prior to this system, doing long calculations was much more complicated and error-prone. Laplace wrote that we do not appreciate the genius of the Indian Number System as it is so simple, yet it was beyond the abilities of the greatest Greek mathematicians, Archimedes and Apollonius. Back in 1817, Henry Colebrooke showed that modern Algebra is derived from the ancient Indian Algebra (bijaganita). The Persian Al Khwarizmi who translated Indian Arithmetic into Arabic also translated Indian Astronomy texts which utilized the Indian bijaganita. Colebrooke pointed out that the Greeks inherited Babylonian Algebra and did not make much improvements on it. Late on in the Greek world (4th Century c.e.) Diophantus did develop algebra somwhat but the Indian Algebra was far more sophisticated and advanced than the work of Diophantus. Modern Trigonometry owes much to the work of Indian Aryabhatta known as the Aryabhatiya (499 c.e.)which also contained a heliocentric model of the solar system and was translated into Greek and Latin centuries before Copernicus. Of course Aristiarchus of Samos had proposed heliocentrism long before Aryabhatta - but note the mythology surrounding Copernicus. Even Calculus originated in India centuries before Newton and Leibniz - see theconversation.com/five-ways-ancient-india-changed-the-world-with-maths-84332

[@sutapasbhattacharya9471]

@cmiller8492 LOL -In your little mind perhaps. Just because you have not heard of it does not mean that no one else has. Eurocentric Westerners hide this stuff but educated people have heard of it! And you use the word 'meaning' as if only what is known to you is meaningful to others! The Iberian Voyages of Discovery used Indian Astronomy inherited from the Moors for navigation [Nothing important indeed to your racist mind]. Astronomical questions supposedly resolved first by the likes of Tycho Brahe etc. had already been solved by Indian astronomers. The so called 'Fibonacci Series' [named after Leonardo Bonacci of Pisa] and other such maths, supposedly discovered in Europe was well known in Ancient India. In the 18th Century, French astronomer Bailly and Scot Playfair showed that the ancient Brahman Astronomy was just as good for practical purposes [predicting eclipses etc.] as the latest Western work of Cassini. As US mathematician Charles Seife stated in his 'Zero'; the mathematical Physics of Descartes and Newton would have been impossible without Indian Mathematics especially the Zero! The Westerners have peddled colonial myths that the rise of Science was due to Greek knowledge. In fact Colonial Westerners concocted their racist Classics and the myth of the Greek Miracle in Science and Philosophy falsely presenting Shamans such as Pythagoras, Empedocles and Parmenides and mystics such as Democritus and Heraclitus as if they were somehow 'scientists'. In fact most Greek Philosophy was no different from mystical Oriental Philosophies [Plato's philosophia meant Love of the Light of Cosmic Wisdom - or seeking Divine Illumination/Enlightenment] and, as numerous scholars have shown, all the elements of Miletian Monism were already well-established in Indian philosophy, Empedocles' '4 elements' were copied from older Indian versions which are actually more in tune with modern Physics than his etc. I myself have identified the physical correlate of what Plato called 'Sophia' - the Inner Light with the brainwaves of the Reticular Activating System - demonstrating the scientific basis of Ancient Yogic knowledge of Consciousness [www.sutapas.com ] In fact the Hindu Nyaya Logic surpassed all formal logic in the West until the work of George Boole in the 19th Century. Robert Oppenheimer wrote that ancient Indian logician Dignaga resolved logic problesm which stumped Frege and Russell in the 20th Century. Panini's ancient Sanskrit Grammar inspired the development of Linguistics in Europe. BTW - if you are British - you probably don't know that as late as the 1790s English experts pronounced Indian wootz steel to be the best in the world and the English copied its techniques. Note that the Brits looted $45 Trillion (£36 Trillion) from India and this loot financed the Industrial Revolution as well as much other Western development whilst killing tens of millions of Indians as they also looted India's foodgrains: www.express.co.uk/news/world/1059012/india-news-bombshell-how-british-empire-stole-36trillion-from-india-lied-spt www.aljazeera.com/indepth/opinion/britain-stole-45-trillion-india-181206124830851.html As H.H. Wilson wrote in 1853, the likes of Manchester could not have risen - not even with steam power - had the British not systematically destroyed the competition from Indian textiles which were both cheaper and superior in quality - this included breaking the fingers and cutting the thumbs off Indian weavers.

[@sutapasbhattacharya9471]

@cmiller8492 LOL Again - Great logical thinking from you there - that development is correlated with the use of Calculus! Oh- I bow to your 'genius' - and your deluded claims to argue with facts! Who except for you is claiming such absurd things! I was responding to your claim that Ancient Indians were not advanced - and showed you that, relative to Ancient and medieval Europeans, they were advanced. Note also that Hindu India was invaded by Muslims from 1200 c.e. and again by the Mughals in 1515 and this led to decline in Indian scientific achievements. But even in 1616 English Ambassador Thomas Roe described Delhi as the Treasury of the World - and the British takeover of India was motivated by the silver drain [much of the gold and silver looted by Europeans from the Americas ended up in India] due to India's world-dominant textiles industry, spices etc. So how comes France which was widely recognized as the world's leading scientific nation in the 18th Century - doing all the decimal/metric standardization and producing the greatest scientists of the era - did not industrialize as discussed in famous works such as Musson and Robinson's 'Science and Technology in the Industrial Revolution'. How comes Egypt was the 2nd most industrialized country in the 1830s - it was not a scientific nation? What about the fact that in the 1840s Paraguay became the first industrial and the richest nation in Latin America but, as this threatened Britain's exports, Britain funded an invasion by Brazil and Argentina which killed 5/6 of the Paraguayans, seized some of its territory and stopped further industrialization [see 'Open Veins of Latin America' by Eduardo Galeano]. It is Politics [not Calculus!!!!] that determines industrial development. The fact that Britain industrialized first had to do with numerous non-scientific factors such as lack of wood due to shipbuilding and the need for coal and numerous other historical accidents! If you bother to read the links I sent about how Britain stole $45 Trillion from India, you will also find that the Industrial Revolution depended upon the massive surplus capital that Britain attained from looting India [prior to this loot and the opium peddling to China, the Atlantic Slave Trade was Britain's biggest earner]. As also indicated, even after the Industrial Revolution started, in the 1790s English experts pronounced wootz steel the best in the world. The fact was that Britain undertook a policy of systematic deindustrialization and plantationization of India to turn it into a source of raw materials. The oldest seaworthy ship in the Royal Navy is HMS Trincomalee in Hartlepool - built by Indian shipbuilders in Bombay in 1817 - and built of hardwood teak so it was superior to British oak. British shipbuilders lobbied Parliament to prevent shipbuilding in India, just as with textile industrialization and other industries. It was only with the 1914-18 Great War in Europe that Britain eased some of its deliberate deindustrialization policies. BTW, I have lived in Britain since 1967 and it is amusing to see how Britain has declined over this period - without the loot from the empire. In the meantime India has risen economically and is currently about to overtake Britain in nominal GDP - and by 2030 will become the 3rd largest economy. By 2050 things will be returning to historical normalcy with India and China probably as the top two economies as they have been for millennia - with the newcomer the USA also a contender.

I am just wondering, say there is an alien civilization just as advanced as us, what kind of mathematical concepts did they invent to describe the universe. Do you think their math would be similar to our math, but just with different symbols for representing numbers, addition, subtraction, multiplication, and division. Or, they have invented some new form of arithmetic and a different way of doing the same thing calculus does.

[@anaccountmusthaveaname9110]

A lot of mathematics arise quite naturally from simple concepts, so I believe that aliens would have similar ideas behind their mathematics. Of course the way of representing those ideas could be very different. Also, a civilization could not be as advanced as us without knowing quite a lot of mathematics.

You didn’t explain how we know the integral of momentum with respect to velocity is Kinetic Energy. You explained how you got the equation, and I get that, but how do we know it’s for KE?

[@bumpty9830]

To show that in full generality would take a long series of videos. You can get some insight from an example problem, though. The most important feature of energy is that it's conserved (in many systems). If we start with an example system, say a weight of mass *m* on a spring of stiffness *k*. The motion of the simple system could be, with a particular starting condition, x=x0 cos[sqrt(k/m) t]. This described a simple oscillating motion, the frequency depending on the spring stiffness and mass. If you calculate the kinetic energy of this system [1/2 m (dx/dt)^2], you'll see that it varies with time. If you calculate the potential energy of the system [1/2 k x^2] you'll find that it also varies with time. The sum of the two, though, does not change with time. In other words, it is conserved. This fact (more or less) justifies calling these two quantities "energies." And, of course, you can verify that the derivative of kinetic energy with respect to the velocity (= dx/dt) is, indeed, *m v*. If you want a totally general answer to this question, you can study up on Lagrangian mechanics. Fair warning, though, this view of things is much more abstract, and also requires comfort with calculus.

[@LongNguyen-pv9sm]

you can deduct that using the original equation, the slope is dy/dx and integral, in the simplest term, is y * x (the area under) it's an established fact that Momentum * Velocity = Kinetic Energy so in the graph of Momentum vs Velocity, if you find the integral (y * x) you get the Kinetic energy it's not the exact explanation, but it serve well as a visualization

[@Earwaxfire909]

Conservation laws are the reasons why we forge these equations. Conserved properties like momentum and energy allow prediction and their meaning is derived from that. "Super kinetic energy" might be valuable if it is conserved in a reaction. Emmy Noether showed that symmetry gives rise to conservation properties. So there would need to be a symmetry condition to make that so.

[@RamadaArtist]

I honestly think they should start teaching calculus a lot younger, and with a more conceptual basis to prepare students for the technical hard bits, so that most people should at least have a handle on it by the end of high school. Because the degree to which people (or, I guess, from my experience, Americans) don't understand calculus is a TRAVESTY, and so many things in every day life would be easier if people thought about them in calculus terms instead of arithmetic terms.

[@saiavinash7432]

I have the exact same reason as you as to why I chose physics as my career, cause it is so cool when you feel like a wizard with the the tools. But I think education system should start teaching calculus at earlier age than University to help them understand why physics is just amazing and why people should go for it, I think this is the reason for people not choosing scientific careers because they just thought it would be memorizing stuff but after they know this, they probably will make a better career choice than a SoundCloud rapper. In India, we start calculus at ages of 14. I think other countries should step up too if they are already not.

[@StratosTitan]

Im more surprised you learned calculus at uni. I was taught calculus when I was 16 (through to 18). That was still part of mandatory education. Now Im at the first year of uni in an engineering degree and we started with a very brief recap of calculus (1-2 classes) and then we did Analysis for the rest of the semester. In the second semester we had linear algebra. Also when we had physics at school we were always taught the derivations of the equations so we would understand them toroughly. Anyhow, great video

[@domainofscience]

That is great! You went to a good school. The UK system is a little different and we do '6th form college' ages 16-18 where you do learn calculus, but only if you take mathematics. So I did learn calculus before University, but only the derivations at University.

[@justin60222]

My high school didn't require calc or physics so my first 2 years of engineering were a bitch. You then get into your junior year and all you did algebra with short cuts to skip the calculus lol.

[@kristiansagia5637]

It brought back to me lovely memories of high school...It applies also to economy if you a cost function of x2 +3x +4 (just and example, the first derivative would be 2x +3 and the area between two points on the curve would be the total cost . Thank you for that memory

[@peterxyz3541]

Sadly, my mind does NOT "work that way", I have trouble learning calculus without applying to something real. You're right, the pathetic American school system doesn't have time to teach application of calculus, instead we get "just do the formula"...my mind need to connect it with something (the motion of stars). What's more sad, I'm MORE prone to use advance math on a daily basis than any of my classmate from high school due to the type of hobby I have (designing airplanes, foils and hulls). Today, I still don't get calculus and hoping someone can explain it in such a way that my mind can connect it with "getting things done" in my life.

[@SneeuwPoesjes]

It's not only american education the same happends in western Europe. Even more sad was that half of the students on my school stopped their physics study at an university (which costs alot and takes away 1 full year of potential studying) after realising it was alot of math, because highschool fails to give a view of what physics is really about. About your calculus problem I think that 3blue1brown has an awesome way of explaning it (you prob tried already since it get mentioned by everyone), but I also like the channel 'Michel van Biezen' this guy has alot of videos where he explains not specific calculus but he uses it alot and explains why he does that , this guy really helped me.

Calculus is basically the rate of change. It basically plots out the gradient of a function. The basics are not that hard to understand.

Il be honest with you. I am a dumbass at math but I am still going for engineering. I am in Calc 2 now and its hell. The amount of understanding needed is crazy. Calc 1 is not hard compared to calc 2. Dont be afraid and dont let anyone tell you, you cant do it. Who cares if you fail calc 5 times, at the end you will get your degree and you will be the winner. If you want to succeed, first dont worry about money, but still be considerable about it.

[@bryanfuentes1452]

i remember when i was in high school, at first I wasn't truly convinced that a derivative can compute the slope of a curve at any point...so i tried to prove it by manually computing, first select any x-value (X1) then get corresponding y-value (Y1) by plugging x to the function and solve y. Now you have 1st point (X1,Y1). To get a nearest point (X2,Y2) to my (X1,Y1) just do the same process but with X2=X1+0.01, then compute the slope of these two points. It will be approximately equal to the value of derivative at that point (X1,Y1).
