Or not. It's a bit hard to follow due to the old style of verbose speaking, but it's all here. These are the words that changed the universe from a magical, mysterious place to something we can understand, predict, measure, and exploit.

It's long and contains a lot of special characters, so I can't copy and paste it.

Lack of modern computers and internet access during that time limited the amount of symbols you could insert into your papers (unlike today's papers :()

Speaking of which, people of that era came up with these ideas through thought experiments. No computers, simulations, or networks of communicating scientists to instantly bounce ideas off of. It's amazing when you think about it. One guy brought a bunch seemingly unrelated observations together in his head to form a complex pattern that the universe follows.

Niggle Alert! :eek:

This would not be "Einstein's actual published paper" but rather a translation thereof, as Big Al (as I like to call him) would have written his "actual published paper" in German.

Aaaaand, so it says it at the end:

This edition of Einstein's On the Electrodynamics of Moving Bodies is based on the English translation of his original 1905 German-language paper (published as Zur Elektrodynamik bewegter Körper, in Annalen der Physik. 17:891, 1905) which appeared in the book The Principle of Relativity, published in 1923 by Methuen and Company, Ltd. of London. Most of the papers in that collection are English translations by W. Perrett and G.B. Jeffery from the German Das Relativatsprinzip, 4th ed., published by in 1922 by Tuebner.

OK, fine, is this any better?

I read Einstein's book in which he attempted to explain relativity to the masses. I was with him until he tried to explain observing the projection of four dimensional shadows onto three dimensional space as a means of detecting what was going on in higher dimensions. My brain said "nope, nope, nope, all done here." I really should read it again and see if it goes any better the second time through.

blows my mind! What could he achieve if he were alive today?!

hmmm...my calculations show that's a bit shy of total energy, and I find more equality in e=mc².

That nomenclature is technically correct, but show me how to make a superscript 2 on a Android keyboard and I'll correct it :)

My undergrad senior thesis in mathematics was writing software for Mathematica that looked at 3-dimensional shadows and cross sections of 4-dimensional objects to try to build a mental image of what the four dimensional objects look like. E.g., most people would understand it this way: take a two dimensional object (let's say a human), freeze it, and then start at the head taking thin slices and work your way down to the feet. Without ever seeing a human intact, it's fairly easy to comprehend how some alien species could look at the slices in sequence, starting at one end and working to the other end, to build a mental image of what the three dimensional object looks like. Likewise, what I attempted to do was look at a sequence of three dimensional objects - rotate them around and examine them, then examine the next one, and so on, from one end of the four dimensional object to the next. I got a lot of headaches.

Hmmmm.
E²= (mc²)² + (pc)²?

Wrong. It wasn't just "one guy". He didn't do it by himself. Many came before him as he frequently cited in the damn article you posted...

That's what One guy brought a bunch seemingly unrelated observations together meant. May not have been clear. Einstein took a lot of genius work and found a way to make it one system.

I seriously doubt that. Science does not work that way. Not usually, anyway. If anything, his work was built upon others, as he clearly stated in the beginning of the paper you cited when he referenced Maxwell. In fact, even though I glanced over the paper, I believe it's mainly about light and energy and magnetism, which is not far off from what Maxwell was talking about.

Again, there were countless physicists, mathematicians, and astronomers whose work led up to Einstein's . You can see it in his references. Having little to no references would've either been extraordinary or a lie. But he has a respectable amount there, considering the era...

Yeah, you're right. Einstein was a hack.
