The STEM Shortage
It’s a myth.
I agree. The problem isn’t a shortage of workers in that field. But innumeracy and scientific illiteracy is a big problem in our society, particularly among the voters. And that includes the illiteracy of those who mindlessly accept a lot of bogus nutrition and climate “science.”
The New Crowdfunding Rules
The SEC is about to release them.
Microbes And Metabolites
An interesting new approach to understanding and curing aging.
Faster, please.
Commercial Supersonic Flight
What NASA’s up to:
“There are three barriers particular to civil supersonic flight; sonic boom, high altitude emissions and airport noise. Of the three, boom is the most significant problem,” said Peter Coen, manager of NASA’s High Speed Project with the agency’s Aeronautics Research Mission Directorate’s Fundamental Aeronautics Program.
There’s a fourth barrier not mentioned: the low L/D, which restricts range and makes for high fuel costs. If that problem doesn’t get solved, it will never become a huge market, and will mostly be restricted to business jets.
The Missing Airplane
Did it shadow another triple seven through Indian air space?
[Update a while later]
Or was it an electrical fire?
Space Solar Power
The Navy Research Lab has been working on it?
Oreo Mining
This is pretty funny.
SLS/Orion
No, Mr. Tito, it’s isn’t a spaceship to anywhere, let alone everywhere, or even Mars.
right now, if you’re an Amazon Prime member. Sales support the Space Studies Institute, I think.
