Julia

No.14421590 ViewReplyOriginalReport
Is Julia worth learning as a general tool for math?
Or should I stick to Python+Scipy,Numpy and friends?
From a first impression Julia looks nice but it also seems like most useful libraries are just wrappers around the common established Python libs.

The fifth postulate is proved by the Voynich manuscript

No.14425427 ViewReplyOriginalReport
Hyperbolic geometries bypass the fifth postulate because they are related to two curved lines by opposition to non-Euclidean geometries that are related to two straight lines, (or about lines with zero curvature), one of which is inclined with respect to the other with angles above and below 90 degrees.

But mirror symmetric curved lines will also follow the fifth postulate in the sense that when rotating them 360 degrees they both will intersect with the central line 9and between them) if the central line is a straight line with a zero curvature, or only the hyperbolic (or parabolic) and the central parabolic (or hyperbolic) lines will intersect if the central line is also curved.

These are self evident statements. The problem about the fifth postulate is to mathematically demonstrate that when the converging side's angle is lower than 90 degrees, the diverging side's angle is going to be inversely proportional to the extent that both angles will add up to 180 degrees.

>learned the concept of a limit, how to find the derivative and how to find the anti-derivative of a function in one day today in less than 1 hour

This is true and yes you should bow down to me, who is more intellectually privileged than you.

Amplitude

No.14425316 ViewReplyOriginalReport
Amplitude of a wave in classical physics is quite a straightforward concept.
However, I've been trying to understand it in terms of photons. What is meant by the amplitude of an electromagnetic wave? Is it analogous somehow to the amplitude of some kind of mechanical oscillator? Or is it just a point in space where the intensity of EM wave is the largest?
