The Edge of the Sky by Roberto Trotta

I get a fair number of books to review, but I’m often pretty bad about writing them up in a timely manner. Of course, most of them are well over 70 pages long, which is why I’ve managed to turn around Roberto Trotta’s The Edge of the Sky: All You Need to Know About the…

“I took a deep breath and listened to the old brag of my heart. I am, I am, I am.” -Sylvia Plath It’s been two weeks since our last edition of our Comments of the Week, and from the heartbreaking to the mystifying, there’s a lot we’ve written about and explored together. If you missed…

The Pleasure of Working Things Through

My bedtime reading for the past week or so has been Steven Gould’s Exo (excerpt at Tor). This is the fourth book in the Jumper series (not counting the movie tie-in novel), and ordinarily wouldn’t be worth much of a review, because if you haven’t read the first three, this book won’t make a lick…

Not really a fully fledged blog post, just a quick link pointing you to something interesting. More than 100%? Sounds funny, doesn’t it? Let me rephrase. Humans have caused so much climate change that some of the climate change changed some of the climate back. Still sounds kinda funny. OK, try again: Humans have caused…

“From earliest times, humans — explorers and thinkers — have wanted to figure out the shape of their world. Forever, the way we’ve done that is through storytelling. It is difficult to let the truth get in the way of a good story.” -Adam Savage When we look back into the Universe, there’s a wonderful, remarkable story that it…

Uncertain Dots 22

After a long absence due to travel (some of which is discussed), Uncertain dots returns! Rhett and I talk about recent travels, how people going into internet-based physics outreach these days would probably do better to make videos than blog, physics in science fiction, celestial navigation, and as always, our current courses. Some links: –…

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” -Carl Sagan That might be true: all the heavy elements — in theory — were created after at least one generation…

The Polar Vortex hurt. We who lived in it, through it, with it, are like farm animals that got zapped by the electric fence a couple of times … notice all that long grass growing by the fence. Stay away. It hurt! So we are worried that this will happen again. It is a reasonable…

The Physics of the Death Star (Synopsis)

“What’s that star? It’s the Death Star. What does it do? It does Death. It does Death, buddy. Get out of my way!” -Eddie Izzard It’s said — at least by Darth Vader — that the power to destroy a planet is nothing compared to the power of the force. But how much energy is that,…

Bad Graphics, STEM Diversity Edition

There was a article in Scientific American about diversity in STEM collecting together the best demographic data available about the science and engineering workforce. It’s a useful collection of references, and comes with some very pretty graphics, particularly this one, showing the demographic breakdown of the US population compared to the science and engineering fields:…
