finished chapter 5 - probably the most boring part of the book so far.
too many metaphors to keep track of, which made the concepts difficult to understand at times, as we go from motorbike on a highway to a cannon on a castle, but don’t worry because in chapter 7 it’ll be simpler
I think this book is too focused on over explaining, that it loses the readers focus regardless

chapter 4 was very content heavy discussing the concept of absolute spacetime. a lot of analogy’s and paradoxes that sometimes did more confusing than explaining. overall I’ll probably have to reread this chapter over (space)time

William of Occam.
Occam’s razor principle is the modern day KISS.
“plurality must never be posited without necessity” = keep it simple stupid

some of the way through chapter 4
talks about invariance, causality, distance and the existence of spacetime
invariance in nature could be the example of walking from A to B and the invariance is gravity working in both points
causality is that certain events have to be in sequential order, eg. your mother has to give birth to you, therefore you can’t exist before her

chapter 3 done
a lot of math but pretty cool
a little too much math towards then end though, but I suppose it is a book on math. made it seem inaccessible to casual readers which the book feels aimed at

these are notes for me
so gamma is the time stretching factor (using y)
y=1/ square root of 1- v^2/c^2
muons moving at the speed of 99.94 percent of the speed of light around a 14 meter diameter ring extend their 2.2 microsecond to 60 microseconds, a factor of 29 which is proved by y.

light as a constant is pretty weird when you think about it, which is the exact prejudice that Einstein was moving past, based on Maxwells equations which were based on faradays experiments.
no matter how fast you are trying to catch light, it is always moving at the same speed ahead of you.
also noting for myself that an axiom is a proposition assumed true

chapter 2 was jumping back and forth heaps between faraday and maxwell, then added some experimentalists at the end; so kind of confusing at times. the idea of the ether was cool. don’t forget: 299,792,458 metres per second

Chapter 1 kinda cool, just Cox and Forshaw saying hey just you wait until you read the rest of this book, and btw Aristotle was a dunce but that’s okay because you could be too. Also big ups to Galileo but then thumbs down for thinking time is immutable

I’ll say this much: Bertrand Russell is a bit of a jokester with his teapot
