I think I am finally gaining an understanding of what is meant by us living in a four-dimensional space-time continuum. I'm currently reading Albert Einstein's book entitled Relativity, The Special and General Theory. In section XVII (page 55) he discusses Minkowski's Four-Dimensional Space. He started out very simply in section I with a discussion of Euclidean Geometry and built all the way up to the space-time continuum. I don't pretend to have understood everything he discussed, but I made a point of ensuring I (at least partially) understood every section leading up to this point. On page 56, he discusses the fourth equation of the Lorentz transformation and it actually makes sense to me! It was definitely an aha moment.
I would recommend reading this book to anyone who wants to learn about Einstein or his Theory of Relativity. The writing style is a little difficult to comprehend at first, but eventually you get used to it. I would guess it is due to the fact that 1) Einstein lived in a different era, 2) it may have originally been written in German (and translated to English by someone else), or 3) Einstein's advanced intellect. Regardless, Einstein does a great job of following one of his famous quotes:
"If you can't explain it simply, you don't understand it well enough."
I'll now have a different perspective on every day life...
