Book review – Gravity’s Century: From Einstein’s Eclipse to Images of Black Holes

When the movie Interstellar was released in 2014, I thought its depiction of a black hole was one of the most hauntingly beautiful scenes. And with input from prominent astrophysicist Kip Thorne, there was plenty of science to this piece of science fiction (see The Science of Interstellar). Amazingly, we only had to wait five more years for an actual image of a black hole – or really its event horizon – to be published. But these astounding images have been a long time coming. With Gravity’s Century, science writer Ron Cowen traces the story back to Albert Einstein and provides an accessible and compact overview of the century-long quest in physics to better understand gravity.

Book review – Nonsense on Stilts: How to Tell Science from Bunk (Second Edition)

In a time of fake news and alternative facts, being able to separate the proverbial scientific wheat from the pseudoscientific chaff is vitally important. But seeing the wide acceptance of a lot of dubious ideas, critical thinking does not come easily. So, how, then, do you tell science from bunk? Updating his 2010 book Nonsense on Stilts, evolutionary biologist and philosopher Massimo Pigliucci once again attacks this problem from many sides. Going far beyond cheap potshots at pseudoscience, I found a book that takes an equally serious look at the more insidious phenomena of think tanks and postmodernism, with a healthy side-serving of history of science. The result is a readable introspection on what science is and how it is done.

Book review – Getting Science Wrong: Why the Philosophy of Science Matters

So you think you know what science is? I thought I did. I mean, we notice patterns, formulate hypotheses, gather observations to see if our ideas are supported or not, and discard or accept our hypotheses. And this is what we do. Yet, as philosopher Paul Dicken shows in this lightly written introduction to the philosophy of science, there is no good definition of the scientific method, though there are plenty of misconceptions.
