Here is the ‘map’ of modern physics in the introduction in the first Motion Mountain volume (603 pages). There are 5 similarly large volumes :O

I've got it on my Linux computer too. 🙂

Volume 4 is currently absorbing me. But had to refer to Volume 1 for the difficult concept of action.

But Sumerian mathematics has caught my current attention,

3^2 + 4^2 = 5^2

and

3^3 + 4^3 + 5^3 = 6^3

makes a lot of sense in Cuneiform. 🙂
 
Too easy, my friend. Babylonian mathematics, base 60. 😀

We shouldn't look down on the Ancients. Maybe they knew something.

I don't mind putting my hand in my pocket to explore ancient mysteries. Who were the "Three Wise Men"? And what were they up to? 😕

Current explorations reveal that "Czech and Speake's" Frankincense and Myrrh aftershave smells quite good. But pricey. About a £100 a bottle. I don't know where the Gold went. 🙁

The construction of even number magic squares, like the one above, is apparently quite a challenge and involves the use of an algorithm (or two).

Odd number magic squares, like the one I first posted, are fairly easily constructed using simple methods.

@ Discopete: Keep looking at the numbers, ignore Steve's divisible by 4 malarky, and consider his earlier Babylonian clue.

I was a bit slow last night! Perhaps because the numbers seemed uninteresting. 😱

But have got it now. How big can you make these things and they still work? 😕

Hardy was visiting his maths friend Ramanujan and got a taxi to Putney, IIRC.

Ramanujan wondered what the Taxicab number was...

"1729" said Hardy. "Seems an uninteresting number."

"Oh no. 1729 is an extremely interesting number." Said Ramanujan.

What was amazing about Ramanujan, is he pretty much invented Elliptic curves. He was trying to solve Fermat. And his intuition was right, because the Wiles proof was based on elliptic curves. Funny things. Almost organic.

Idealism belongs to mathematics. Empty space would be purposeless, energy transfer would not be possible and the Universe would not exist. Discontinuity is not allowed in Nature. The interstellar medium has had many names during the centuries. I strongly dislike the name vacuum, it reflects an unphysical view, the view of a bunch of mathematicians.
Math is by far not my strong suite, but if we have a long and hard look at everything in known existence I find the only number that is completely unrealistic is "0".

In terms of math complexity I usually draw the line at ohms law.
But for me, fluid dynamics and mass falls under a segment within "dimensional understanding".
Things like mass density and fluid dynamics is easy to just imagine to a molecular level, since there's no shortage of comparisons in everyday life. Everyone can think and understand what lower or higher mass entails, likewise with fluids of higher or lower viscosity.

Hey, this is beautifully said!
Perhaps I may be misinterpreting, but I find this somewhat condescending.
Just because I avoid most theory on the basis of cumbersome, poorly worded and inflated text, it does not translate to me being an illiterate.
Atomic matter comprising massive, highly compressed, hard nuclei makes up a much more dispersive and slower medium.

Quite, but if you look at it at a lower level you will see that the electrons around nucleus will have higher activity with increasing mass. Even if the end result is like you say a "slower medium" that is more because of the amount and distance between the atoms interacting with each other, I guess it could be said that the medium itself is actually "faster" since the level of activity is higher.

Everyone should feel free to correct my potential misunderstandings.
