_"They deal with this messy thing called reality."_

[Tirnts]

This man appeared in my dreams and gave me a lecture on quantum physics

[saumyaranjan]

I thought mathematicians and physicists are going to fight with armour on. Guess i was wrong

[TeamDemoClan]

Why study applied maths, when you can study pure maths and let physicists apply it for you in 100 years ;)

[iammaxhailme]

When I went into graduate school (for chemistry), I realized that much of the subject can be reduced to purely mathematical group theory.

[TeeCaTisBack]

I love how emphatic he is, look at him smiling when talking about the sum of histories. He's probably told this 100 times and it still excites him

[swankitydankity]

Why does everyone want to establish some sort of hierarchy of science(s)? It's not like Maths > Physics or Physics > Maths.
For a physicist, math just happens to be a tool of the trade, but a mathematician is far more specialized on maths rather than its applications. It's not like a physicist is better than a mathematician or vice versa.

When I saw the title I was expecting to see all of Numberphiles mathematicians and Sixty Symbols' physicists battling it out. Not disappointed though

[dmunter]

The idea of math being grounded in our physical experience is explored well in Lakoff and Nunez' "Where Mathematics Comes From." Highly recommended book if you are interested in a more anthropological/psychological perspective on why we care about the kind of mathematics we do!

2:29 "This is a Pen" for a very brief moment I expected him to say next "This is an apple". I need to spent less time on the internet.

[disgorgeengorge]

"Anyone who claims to understand quantum theory is either lying or crazy" -Feynman supposedly.

[Sukhraj_Sekhon]

"This one is knot and this one is not" probably could've been phrased better lol

[Soulthym]

7:13 turn on autogenerated captions to learn what knot theorists really study

[ShinySwalot]

My first year of my study was opened by this man, amazing lad

[unvergebeneid]

How do you find all these great communicators, Brady? I mean it's one thing to find smart people but to find smart people who have such beautiful language or can explain things so well? Do you have castings for your channel?

[EgoLTR]

Whoo Robbert Dijkgraaf! Our Dutch national treasure. Such a smart and inspiring man :D

[DaniErik]

8:37 Is that a reference to Newton's famous line: "I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."

[ethanchaney]

This is the reason I decided to focus on on math more. This stuff is so cool and I feel that if I keep studying and getting into higher math classes I get to learn and understand this. This channel is one of the reasons I want to pursue math. Thnx

[mrnarason]

Taken two semsters of quantum, might as well would've been math classes. Also, it is interesting to see physics advances math since it is mostly the other way around, ie, green function, qunatum mechanics, math to physics, and orbital mechanics, calculus, physics to math.

It's a pity that this guy is not a regular at Numberphile
