This is as much a history book as it is a science book, so it strongly appealed to my polymath tendencies (I should really write a post about the polymath/Renaissance Man concept). In fact, if I were going to teach an introductory course on thermodynamics, or wanted to introduce someone to the topic, I would highly recommend this book, rather than using a more traditional textbook.
There are certain principles that I have found underpin an astonishing number of our modern systems, and gaining a thorough understanding of a principle like that can enable you to understand or surmise how so many different things work. One of those, which is what we will be discussing today, is the photoelectric effect. It seems like at least once a week I come across some new piece of technology that leverages the photoelectric effect in a completely new or different way, and increasingly I marvel at how such a relatively simple principle underpins so much of our modern world. So let's talk about the photoelectric effect.
We've been hearing a lot recently about how we need to "trust the science," and "follow the science." Anyone who does not agree with the science or the above statements tends to be labeled as unintelligent, ignorant, or otherwise mentally backward, perhaps irresponsible. It is one thing for politicians to use such phrases for political leverage and advantage: science has been invoked for political purposes for about as long as science has existed. To me, it is far more dismaying to see people who claim to be scientists themselves undermining the very essence of what science is supposed to be.
