# I teach Cheeeeese Special Relativity!!! watch

1. CheeseIsVeg

First we need to explain the two axioms of relativity:

1) The speed of light will be measured to be the same regardless of the motion of the source or the observer.

2) There is no experiment that can be conducted to determine absolute motion.

Before we start, good luck mate
I am aware of the first point. (Use it in my EPW )
Absolute motion being?

An experiment conducted on the Earth and one on a train would give exactly the same results. One would not know that one was moving.

Absolute motion is motion that does not depend on anything external to the moving object for its existence or specific nature.

AH
I recall going to a lecture by a Cambridge Physics Admissions Tutor about this
Mind-boggling tho

So, if we all agree that the speed of light is the same, then we could use a light clock to measure time.

The light clock is a simple way of showing a basic feature of Special relativity. A clock is designed to work by bouncing a flash of light off a distant mirror and using its return to trigger another flash of light, meanwhile counting how many flashes have occurred along the way.

How would the ticking of the clock change for an outside observer looking at one that is on a moving train?

Oh
Is it because the light takes longer to reach it so for them time slows or.something idk

Exactly. See above video, if you haven't already

Later, i gtg
12. this Relativism stuff is so last century !

today it is all about Cheese String Theory ... get with the now daddio !

14. This is cool

Thanks
16. This is quite tricky to imagine because it just doesn't seem rational to say that time is different for different observers. It's so mind boggling

Time and space are different to different observers, but mix them together into spacetime, and everyone agrees on that.

scientists already suspected that Cheese is at the root of Quantum Physics. early versions of Quantum Theory relied heavily on ...

this is Up Quark. if you rotate the image you generate Down Quark.

I love me some physics
