Reminds me of my math professor. One time our physics professor was out for a personal emergency just before midterms, and we frantically looked for a fill in, but all the science profs were in other classes that hour, so I thought of my math prof, who had the session open, and we were just using calculus to solve motion problems anyway, and some examples in calc class were the same exact problem as we worked in physics class. So a little maneuvering, and it was approved for him to fill in. We went through the homework, and he vetted our answers ok. Then he put the next sections problems on the board, and asked for volunteers to work them. We set some variables to zero, allowing us to narrow the equation, then set the two intersecting forces to equal so we could start eliminating unneeded elements. And he said, hold on, how are you doing this, what proof do you have that these can be equal. The answer of course from a physics perspective is it doesn't matter. If I drop a rock it will accelerate from gravity until it hits the floor, then the height, and velocity will be zero. His answer was "you physics guys sure play hard, and fast with the rules of mathematics". And pointing to me, "don't you try this sh@t it MY class". Which is a basic difference. In math everything has to be proven mathematically. In physics, you use math to get you in the ballpark, then pull out a ruler, and measure it. My proof, I dropped an object, it is now resting on the floor, measured height = 0.

[@thestoned6862]

The actual science of logic is conversant at present only with things either certain, or impossible, or entirely doubtful, none of which (fortunately) we have to reason on. Therefore the true logic for this world is the Calculus of Probabilities, which takes account of the magnitude of the probability which is, or ought to be, in a reasonable man’s mind. -James Clerk Maxwell

[@amatya.rakshasa]

As a math Major, I totally agree. Pure mathematicians are just in pursuit of incredible intrinsic beauty within math. They're not doing stuff because it often winds up being connected to real life things or to help physicists or engineers or economists or whatever. They are not doing stuff to make the world a better place, although math frequently winds up doing so. They're just in search of beauty and mathematical truth, mathematical structures and connections, and mathematical meaning (not real life meaning or physics meaning or economics meaning or whatever). That's all. I would recommend checking out GH Hardy's "a mathematician's apology", he talks about these issues of mathematical beauty and real life. Hardy was one of the top two or three number theorists in the world in his time and was the mentor of the genius Ramanujam.

[@dasbloekendeschaf]

I always thought defining the purpose of math as the pursuit of beauty is rather absurd. Very few of the great theories would have been found had it been only a better pastime for its inventors.

[@amatya.rakshasa]

@@dasbloekendeschaf The way Hardy explains it, and I agree with him, is like this. Say you're a basketball player like Jordan. If you ask Jordan why he plays basketball, he may say that it produces a social good like entertainment/inspiration etc but the truth is more like 1) he is very good at basketball, 2) it is super amazingly fun to play basketball, and 3) he wants to kick everyone's ass and accomplish something in basketball. According to Hardy, those are the true reasons behind pure mathematicians doing math. They are really good at math, math provides them with an immense amount of pleasure (you can also call it pursuit of beauty or fun) and they are ambitious and want to make a name for themselves in the math community and in history. Pure math gives you a kind of immortality. We are still talking about Pythogoras and Newton etc and always will if there is civilizational continuity.. much more than we would be talking about a poet or politician or a businessman from a different era. Yeah sure, math winds up being the language of physics and the language of universe and really helps with engineering and literally every other field of human enquiry and winds up having social value but.. that's not why mathematicians do math. Nobody does math to make the world a better place. People do math for the reasons Hardy described. In a free society, people should be allowed to do things for whatever reasons they want. In a communist or state controlled society, people should let mathematicians do math because they love it and the rest of us get this positive externality.

[@dasbloekendeschaf]

In my senior high school years I had a hard time understanding math as nearly nothing being taught to me felt real. it was all abstract. But when similar looking equations and formulas where being used in my physics class to explain a real world situation my mind lit up and I was fully engaged in the learning process. I think the WAY they taught us mathematics was unnecessarily difficult. But then again maybe one of the major goals of teaching us mathematics was to exercise our ability to think in an abstract way. A lot of immensely beneficial things we enjoy today spent a lot of time in the mind of an abstract thinker before coming to life.

Being an Engineer learning calculus and linear algebra, I've always tried to connect math to the real world because that's what's expected from us engineers. I realize now, that it was never the job of mathematics to manifest in the real world every time, but instead, that is what physics is designed for. Eureka moment, thank you Feynman!

[@eddarby469]

I don't even believe Physicists are the group that makes math connect to the "real world", but they find physical phenomena and attempt to quantify the nature of things in mathematical form. Engineers often take the results and test the applicability of these relations in specific cases, and then throw out the specific terms that are infinitesimal in their specific case or replace them with a constant or simplified expression that will produce a useful result to solve the problem within specific parameters. For example, for most of us engineers, gravity is 9.81 m/s "down", and this gives us something useful for our problems. But to a physicist gravity is an equation that includes the mass of both objects to determine their attraction to one another, and it has to have a direction vector, when most engineering applications can just use, "down".

[@Ennar]

Good for you to realise this. We all do our jobs. But just to make sure that this is clear, mathematicians don't just come up with new axioms and theories willy-nilly (usually). If your theory doesn't solve any of the old problems, it will be hard to convince any mathematician that it's worth looking into. New mathematics is born from the fact that you solved some open problem and then bunch of other people get interested and expand the theory in search for other interesting applications. It's always a cycle: come up with something new to solve old problems, investigate the new theory on its own, create new problems, rinse and repeat.

Not all patterns can be expressed mathematically, not just due to gaps in our knowledge, but due to certain mathematical concepts which contradict the notion that all patterns can be expressed mathematically. A few great examples of this including the "Haulting Problem" from computer science, as well as Godel's incompleteness theorems. Both of those examples show fundamental gaps in the abilities of math itself, not just human knowledge.

His statement that mathematicians don’t use intuition and don’t know what they are talking about is absurd. It’s required that proofs be rigorous but the method to getting those proofs is anything but that. Mathematicians make guesses and conjectures all the time and pretty much nobody ever ends up proving something they didn’t first intuitively think was true. Anyone who studies maths also discovers this for themselves. Consider an analysis class studying metric spaces. Sure, maybe a physicist would only care for euclidean distance. But the more you work with it the less you care what the metric actually is. You begin to get a feel for what things can be proved without even knowing what the distance between two points is.

That way of teaching only works for maths majors and even then, you need to come up with examples, even though the examples for maths majors come from less abstract maths.

I still often give up and narrow towards just seeking what yields the most fun and beauty, and repurpose towards hedonism, but i still do hope that one day when the time comes for me to solve problems i find impractical, that i will forge ahead regardless, try to make what feels in vain, not so.

Physicists, chemists, engineers etc don't need to care why a formula exists, they just need to know that it works and that they can use the existing theory to build more complicated models and theories that can help explain or construct certain things in the real world. Mathematics relies on logic and axioms, but physics and engineering relies on existing math concepts.

That's not true. Physicists definitely are struck by certain formulae and want to dig deeper into their meaning and "reason" for existing. A nice example would be the path integral for which Feynman is famous, which has its routes in the action principle of classical physics. Physicists simply care more about connecting physical ideas rather than mathematical ones. That doesn't mean they treat all formulae as mere phenomenological models that must be made more complicated to fit more circumstances. In fact, usually the opposite has happened. Simpler and simpler formulae describe larger and larger collections of phenomena.

If physicists were not interested in generalisations, there would be no physical theories. There would be a description of one specific apple falling from one specific tree on one specific planet, but no theory of gravity that explains planetary movements, ballistics, and orbits, all at once. The difference between mathematics and physics is that in mathematics, truth is in not being self-contradictory, while in physics it is experiment that decides what is and what isn't true. This means that things that are impossible in mathematics are also impossible in physics (which makes it unreasonably effective), but things that are possible in mathematics need not be true in physics (like for example string theory). It also means that mathematics is flexible enough to describe any model of physics in infinitely many ways; and there is no one simplest way to describe any aspect of physics. (Physicists often think of mathematics as a language to describe physics, but mathematics is more a mindset for constructing languages; there are mathematical formalisms for describing different kinds of languages. Newton's algebra is a language, but just one possibility of describing mechanics, and apparently not even the most elegant one. It also runs into problems where Newton's chosen units cancel out, but don't mean the same thing, like with energy and work and enthalpy.) In practice, physicists often don't use rigorous mathematics, but crude approximations that are close enough for all practical purposes. (For example, sin(x)=x for computing interference patterns; it works for small enough x. Another is Feynman's way of integrating the infinities of virtual particles between two measurements: he just ignores all but the most probable.) Much of physics is completely unintuitive, even counter-intuitive (for example Galileo's magical tricks with pressure), which is why mathematical rigor is needed. Somewhat ironically, mathematicians often develop intuitions about mathematical things (most famous is probably Taniyama's conjecture which turned out to be completely true). Which contradicts Feynman here with empiricism when he says that intuition can be applied in physics but not in mathematics.

I used what was previously completely unknown (the 0 sided non-dot polygon) to do another integration/derivation-related dimensional shift and I arrived at what I could only describe as the hidden divine living ever-changing ever-growing creature called Pi, which grows in observation much like (if not more) than any human beings.

I have noticed that I have mixed theoretical analysis with practical-verifiable scientific analysis many times, which allowed the chance for pranksters (of many diverse and distinct mixtures of abilities) to leave doodles during my personal quest for creating the strongest surviving pillar of no stress-points for my metaphysical museum of knowledge and tales of wisdom. If my mind can create, then so could it survive any harm I or others may do onto it. During the prank by the divinity or the middle-person between me and the offspring (division) of people's arbitrary reassignment of shapes and forced convergence of spaces (curves and lines should never exist in the same reality but they do), I did acquire some tricks and techniques from the so-called lifeless meta-world.

Paul Dirac was known for his reserved nature and his preference for working quietly and independently. Unlike Richard Feynman, who was known for his charismatic personality and penchant for showmanship, Dirac was a quiet and introspective individual who preferred to let his work speak for itself. Despite his reserved nature, Dirac's contributions to the field of physics were immense. He made groundbreaking discoveries in the areas of quantum mechanics and optics, and his work continues to influence modern physics to this day. Dirac's humility and dedication to his work are qualities that are highly respected by many in the scientific community, and he is widely regarded as one of the greatest theoretical physicists of the 20th century. In many ways, Dirac's quiet and unassuming demeanor is a testament to the power of the scientific method, which values rigorous experimentation and objective analysis over self-promotion and grandstanding. Dirac's legacy as a humble genius is an inspiration to scientists and aspiring scientists around the world, and his contributions to the field of physics will continue to shape our understanding of the universe for many years to come.

Are you saying that Feynman was not interested in "rigorous experimentation and objective analysis"? and one example is his invention of the Diagrams...?...

Strong talk Feynman.
