The Lorentz factor

Simon has just graphed this to show how the Lorentz factor or gamma ( on the y axis) is dependent on the speed of the object (the x axis). The 100 on the x axis is the speed of light. You can see how the speed makes virtually no difference to the Lorentz factor (of relativistic time and mass) until the speed of the object reaches about 85 percent of the speed of light. At around 90 percent of the speed of light the Lorentz factor reaches 2 (which means that time is twice as slow by then and the relativistic mass doubles), and at 99 percent the factor is already 7. For 100 percent or the speed of light itself, the Lorentz factor equals infinity, Simon explained.

False Proofs: Can you figure out what’s wrong?

Simon shows three false proofs. Can you find the mistake in each proof? Simon reveals the answers to the first two. Try to give your answer to the third one. 

And the answer is: 

The math behind why we can’t travel faster than light

Simon prepared 19 pages of notes!

Simon walks you through several special relativity paradoxes and a brief proof of why nothing can move faster than light. He shows the working out of the distance formula.

Based on the following video tutorials by Sixty Symbols:

Amsterdam Light Festival

Simon’s first long boat trip, to see all the artwork presented at the Amsterdam Light Festival this year. Pleasantly surprised at how many pieces were inspired with his favorite themes (glass fiber, RGB perception, string theory, neural networks).

This photograph seems to convey the essence the artwork! It’s about string theory, and when you move relative to the piece the strings flicker (vibrate). Try scrolling up and down and you’ll see the same effect!

Simon’s findings about the relationship between the exponent and the factor of a number

Simon explains why the proof that root 4 is irrational is false and shows a couple more related theorems (he came up with) generalizing the relationship between the exponent and the factor of a number.

Simon’s generalisation: 
if a^n/m
then a^n/m^n
