Does Death Exist? Such a question might seem inappropriate for the Sci/Tech section but, relax, I'm not going to talk about religion and the afterlife, I'm going to talk about quantum mechanics. Or more precisely, the consequences of certain popular interpretation of quantum mechanics. Quantum mechanics is first of all a mathematical tool for predicting the results of all sorts of experiments. This tool happens to be incredibly accurate - its predictions fit the facts extremely well. However, when people start wondering about the actual significance of what they're doing, things get tricky.

One of the most popular interpretations however, and which is now supported by the proponents of String Theory (one candidate for the so called grand-unified theory - of quantum mechanics and gravity), is that the mathematics of quantum mechanics actually reflects reality itself. This may sound like rubbish (if it weren't for the experiments). Image credits: Touch of Death #3 cover, G.W. List of colors. Einstein for Everyone.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door.

With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. I i i. List of common physics notations. Relativity: The Special and General Theory by Albert Einstein.
