Welcome to Theoretical Thursday!
Today I start a new journey of expoloration and learning. I will endeavor to learn Theoretical Physics. For as long as I can remember I have loved science – the idea that things are discoverable and understandable largely just by being observant. The life cycle of an insect, the growth of mold on bread, the magic of a healing cut, etc. And in physics class - A ball in a wagon is set in motion when the wagon is pulled. When the wagon stops, the ball keeps moving… etc. I get that. After all, I was the girl who scored the highest in all things mechanical on some Junior High assessment test (you had to follow the cogs and wheels of a machine and draw the direction of movement for each.)
But then I hit a road block – theoretical explorations where things like quirks, quarks and the Higgs-Boson particle are spoken about as if they too were sitting in a wagon. As I type this sentence, I realize that my ignorance may be showing and these things are real and observable and I just haven’t understood the conversation. And that is the impetus for this experiment – I want to understand the conversation. I want to understand how very smart men and women can earn a living by making stuff up. At least that is what it seems to me, right now, in my theoretically-challenged brain.
This book, written in MCMLXI, includes a preface. “The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.” I fit that bill – I am interested. And I am not conversant. So far so good.
His next sentence (Don’t worry, I’m not going to go through the whole book sentence by sentence. I think.) presumes I have an education of a standard “corresponding to that of a university matriculation examination.” I have a Masters in Anthropology, but that probably isn’t what he meant. I suspect that exams in MCMLXI might have been more rigorous than they were when I graduated, but I can’t be sure, so I press on.
The book also presumes, “…a fair amount of patience and force of will on the part of the reader.” Hmmm. Might have a problem there. I didn’t have much force of will last night when I ate 4 bowls of popcorn and a couple glasses of wine. (Note: it was “Smart Popcorn”) However, Albert promises that he has written the book in a ‘step-motherly-fashion” (and I’m hoping that doesn’t mean evil Cinderella’s step mother) and he hopes the book may bring someone “a few hours of suggestive thought!” (Albert, you dog! I don’t know about a few hours worth, but I like a suggestive thought now and then.)
That preface was written in December 1916. The edition I have is the 15th edition and on June 9th, 1952 (8 years before I was born) he wrote a short note about the addition of a 5th appendix about the “problem of space in general and on t
