Physical Science

“The most amazing lesson in aerodynamics I ever had was the day I climbed a thermal in a glider at the same time as an eagle. I witnessed, close up, effortlessness and lightness combined with strength, precision and determination.” -Norman Foster It’s called the “Eagle Nebula” because the shape of the nebula itself faintly resembles…

“I would give my life to fly in space. It’s hard for me to talk about it but I would. I would then, and I will now.” -Jerrie Cobb, at age 67 in 1999 Some of the greatest heros of the 20th century are those who were an integral part of humanity taking our first…

“Out, you impostors! Quack salving, cheating mountebanks! your skill Is to make sound men sick, and sick men kill.” -Philip Massinger It’s been a wild ride full of ups-and-downs this week, as we’ve covered topics from solidly-based science to the theoretically expected, all the way to physical impossibilities and unverifiable, outlandish claims. Sometimes, that’s what…

How many lakes are there?

How many lakes are there? We don’t actually know. Lakes are often undercounted, or small lakes ignored, in larger scale geophysical surveys. It is hard to count the small lakes, or in some cases, even to define them. A recent study (published in Geophysical Research Letters) examines this question. We want to know how many…

“I must choose between despair and Energy —— I choose the latter.” -John Keats Yes, we know that the fabric of the Universe is not made up of space and time but rather a unified spacetime; that the spacetime isn’t static but rather expands as the Universe goes on; and that the expansion isn’t slowing…

In odd-numbered years (by the Gregorian calendar, anyway), the University of Toronto offers the John Stewart Bell Prize for Research on Fundamental Issues in Quantum Mechanics and Their Applications. This is not connected to the Jon Stewart of the Daily Show– he’s purely classical, as you can tell from the fact that there’s no “h”…

“Between cold fusion and respectable science there is virtually no communication at all. …because the Cold-Fusioners see themselves as a community under siege, there is little internal criticism. Experiments and theories tend to be accepted at face value, for fear of providing even more fuel for external critics, if anyone outside the group was bothering…

Official Prediction of US Winter

The National Oceanic and Atmospheric Administration (NOAA) has released its official prediction of what this winter is going to be like. And yes, it is in ALL CAPS!!! I’ve pasted it below, but first a summary of the relevant points. According to NOAA El Nino There will be a weak El Nino, late Autumn or…

Entangled States at TED-Ed

The fourth video I wrote for TED-Ed is now live: Einstein’s Brilliant Mistake: Entangled States. The title is not just an Elvis Costello reference, but gets at the fact that while the Einstein, Podolsky, and Rosen paper was wrong in that the local hidden variable theories they favored are impossible, it turned out to be…

“There’s a mark born every minute, and one to trim ‘em and one to knock ‘em.” -David W. Maurer, The Big Con (1940) But how could you tell? There’s lots of amazing science going on out there, and none of us can be experts in it all. Moreover, even when we think we know how things…
