    I taught my 7yo niece to count in binary. I framed it as "I can count to a thousand on my fingers". Then I put stickers on each finger with the numbers 1, 2, 4, 8, ... and showed that you can make any number by adding up the fingers that are touching the table. She enjoyed telling me which fingers I should put on the table to make different numbers.

    Great conversation! Regarding communication between disciplines:
    When I was a PhD student in music theory, I taught several undergraduate music theory courses. A senior math professor asked to sit in on my class because he liked music. For the first few weeks, he was catching up on the music jargon and some notational issues. Once he understood that, I was amazed at how insightful he was at looking at music theory problems in different (and often more efficient) ways.
    Similarly, I don't have any formal training in math beyond basic high school classes. However, I took a PhD seminar on music and computation/math where we analyzed and composed music using various math techniques (some stats, combinatorics, etc.). It took me a while to get used to the jargon and notation of math and computer science, but once I did it felt like a whole world opened up, and now I work as a machine learning scientist for speech and audio understanding.
    I think there is so much different disciplines can contribute to each other, and I love that both of you and others are calling for better ways of stepping into and understanding jargon that prevents so many people from understanding a topic.

      Whoa, this is so great !
      Can you please elaborate how exactly you picked up the relevant math and stats/ ML skills ? For instance, how were you able to take classes on Statistics, ML, Linear Algebra in order to prepare for such a change of career ?

    • @DanielTompkinsGuitar
      @DanielTompkinsGuitar 3 роки тому +2

      @@SayakKolay I was very interested in math and music, so I learned a lot of math independently online. I also had a music professor who also had a math degree. He taught me a lot and pointed me towards several resources.
      Perhaps the biggest thing is that I learned a ton of math by learning to code. A lot of things became very intuitive when I wrote them in code rather than mathematical notation.
      Also, with high-level programming libraries like sklearn, keras, and pytorch, you can build some basic ML without knowing all the math. I did that and then learned the math behind all the operations once I had some intuition about how things worked. It turns out that ML doesn't really require very advanced math, and modern coding libraries take care of the details so you can focus on the big picture.

      The classic proof of the Abel-Ruffini theorem uses pages and pages of algebra and is a bit of a tedious slog. The modern proofs, using Galois theory, are much nicer and much more general, but they are also much less accessible. For most people, it takes at least two semesters of intro abstract algebra to work up to a full understanding of that proof. I don't think I've ever seen an accessible presentation of that proof, and I'm skeptical whether it's possible.

    An engineering student now. My parents are immigrants (who moved to the UK) and we were quite poor and back in their home country of origins they weren't really educated especially after the devastating impacts of war and famine that held back our people for many years and so Mathematics, Science, and Engineering isn't something I found a love for or really understood until the last year of middle school where I started to teach myself Mathematics and Science in an already muddled, rubbish curriculum, that didn't teach help children find what they love and help them understand it, but just taught children for the sake of passing the exam. So, teaching myself and understanding the beauty was the catalyst for everything up to now.
    I also quite envied children who did have parents and role models that helped them understand the importance of knowledge, learning, and education (especially if it was Maths and Science) but at the same time I am really grateful for my parents for bringing me up and putting food on the table and always caring for me.
    Only thing one can do is move forward and keep striving for the ability to see the beauty in things!

    There is so much interesting stuff out there but the signal to noise ratio is low in journals etc so it would be nice have a map of universalities and the top teaching resources, like a Wikipedia stack-exchange UA-cam mashup.

    The problem with cell towers at around the 50:00 minute mark reminded me of an engineering video I watched about culverts; there are many ingenious designs to improve flow rate, but often the best and cheapest solution is just to make a slightly bigger culvert.

    1:09:12 Alex is thinking of Alfred North Whitehead and Bertrand Russell and their multi-volume opus Principia Mathematica. They had three goals (see Wikipedia for details), but the key one had to do with resolving the paradoxes that (ironically) Russell discovered in set theory. These paradoxes appear due to self-referential constructs (see Russell's Paradox). A more accessible paradox that Russell himself used to illustrate the issue without involving advanced math concepts (just logic) is known as the Barber Paradox ("If a barber shaves all those, and those only, who do not shave themselves, does the barber shave himself?").
    Whitehead and Russell do indeed take 300+ pages to prove that 1 + 1 = 2 (an "occasionally useful" proposition, as they called it). To do that they first invent a system for describing any statement, formula, equation, etc. in notational form. The goal being to prove that mathematics, as we know it, is consistent and to resolve the paradoxes.
    In 1930 and 1931 Gödel proved that no mathematical system can be both consistent and complete (and that our math is consistent, but incomplete). Indeed, he used Whitehead's and Russell's notation in his proofs. (An incomplete system cannot be used to prove all its propositions, rather, there must be at least one true proposition that cannot be proven--an axiom.) How he constructed his argument is fascinating in its own right and worth exploring. "I'm a Strange Loop" details the paradoxes, Whitehead's and Russell's attempt at resolving them, and Gödel's proof in a highly accessible and readable form. But for the impatient who would like to get the half-hour version of things (instead of 400 pages), see Veritasium's ua-cam.com/video/HeQX2HjkcNo/v-deo.html

    God that early example about fluency vs abstract thinking was my second year of uni doing vector calculus and complex analysis. Every example of a complex integral I was given just boiled down to the lecturer saying "just use Cauchys theorem here..." to the point where by the end of the class I didn't know how to actually integrate a complex integral. Like, at all. It took years later and rediscovering parameterisation and stuff like that before I could even make sense of a contour integral because I was just bombarded with theory and no rote learning. Vector calculus was the same. Green's theorem this, divergence theorem that. I just wanted to *do* the integrals, god dammit!

    One thing about Lean and Coq - how do you proof that there is no mistake in checker itself? Like, for example, Rust programming language were claiming that it is memory safe if you don't use "unsafe" blocks. But then, counter example appeared, without unsafe blocks but leaking memory.

    1:05:00 I know nothing of the progress of automated proofs. Are we to the level where we will build a database of all papers with formalised proofs and use those very simply to guide complex demonstrations? Or is it just a basic software with only a standard library of common theorems?

    • @yaeldillies
      @yaeldillies 3 роки тому +1

      Well I can speak for mathlib in Lean at least. Some areas of mathematics are well into formalization (number theory, category theory...) and others aren't (analysis (it's very advanced, but the low level stuff is hardly usable because everything is so general. We are still lacking specific theories, like real and complex analyses), combinatorics...). A good indicator we keep track of is whether we can give a standard paper to a Lean-trained undergrad and have them formalize it without needing to formalize even more basic theory. We also sometimes formalize IMO problems, but of course the maths involved are pretty limited.
      But really mathlib is a big monolith of mathematics that everyone expands in a different direction. People push for improvement in diverse areas of maths and if something hasn't been formalized yet it's most likely that nobody has yet been interested in it enough.

    As a chessplayer (IM and pretty close to GM at some point in time ) I find pretty normal that chess programs learn more from their own playing than from a human chess database. Humans apply general rules and principles while computers go straight by shear computing power. A computer will always play the best move but humans will generally play the safest move. As Kasparov described Karpov once , he plays " a pretty good move". For a computer there's no point in studying strategy separated from tactics (as humans do) cause there is no any difference on how computer operates.

    I once heard a lecture on number theory, it was how some GPS problem was solved with Chinese remainder theorem, it was far beyond my level, I was in calc 1, as a result I really don’t remember it.
    If you’re looking for an insight of abstract , mostly theoretical seeming mathematics can have practical real applications.
