We should also wonder why only 20% of deaths in Japan occurred outside care-homes, since that's a lot lower proportion than in Europe, where...

Well, with the same total irradiance, our planet receives only 2% of the Earth's illuminance. But the remainder of the irradiance is coming in as...

I don't think you'd see shadow bands. Plugging in values for an O3V from Lang's venerable tables (52500K, 15 solar radii), I get an apparent...

Excellent vaccine uptake in Scotland so far, as we work our way down the age tiers. According to the Public Health Scotland Covid dashboard, we've...

It seems that people are resorting to creating bots to deal with the complicated and multithreaded booking systems in the USA. Grant Hutchison

Period squared varies inversely with mass and directly with radius cubed. Grant Hutchison

Square root of the bolometric luminosity of the star, times whatever boundaries of the solar habitable zone you care to adopt. Trying to do any...

Yes, if Earth had no atmosphere and was equipped with some sort of frictionless racetrack around the equator, you could theoretically set down a...

Well, the fact these vaccines hijack cellular machinery at a genetic level was a legitimate cause for concern, a decade ago. It certainly seemed...

The mRNA doesn't directly induce an immune response. It codes for a SARS-CoV-2 protein, and uses your cells' ribosomes to make the cells churn out...

The problem in the specific setting I encountered (though it was far from unique at that time in Scottish culture) was that Scouting did all that...

That's a failure mode of jet engines, called compressor surge. I think it was a common problem with early jet engines, but I haven't checked. In a...

I had eight years of bullying by my noxious little peers as a child, but in that particular setting the adult supervisors were pretty much the entire...

Confined to a small, urban Local Authority Area by current lockdown restrictions, I've had to get creative to motivate myself to keep taking my usual...

Well, I described the "best case" I imagined from DaCaptain's description of the asteroid eventually "touching" the Earth--some undisclosed energy...

If your co-orbital satellite gets close to the Earth, it's going to be effectively in an orbit around the Earth, under the influence of Earth's...

Yes, relativistic length contraction doesn't work at right angles to the velocity vector. (I don't know what "slipstream" means in this context, but...

Yes, the relevant Horizons issues for the Collier's "Man Will Conquer Space Soon!" series are July/August 2012 to September/October 2013. They're all...

We now know that coinfection with Covid and flu doubles your risk of dying, compared to Covid alone, but that there also appears to be a protective...

Yes, that's what I was attempting to convey by the phrase "ill-advised rant". These things should never be addressed in public, or when emotions are...

Yes, that's what I was joking about. Grant Hutchison

You could try dressing up as each other. What could go wrong? Grant Hutchison

Antapex. Yes, Aquarius. Grant Hutchison

Ah-ha. I was imagining that the student was looking at some sort of speech-to-text device. But now that you've posted this, a quick search tells me...

Cosmic microwave dipole gave me the answer on the first hit: Grant Hutchison

The asteroid is going to be orbiting faster than the Earth rotates. So--sonic boom in the atmosphere, friction with the surface of the Earth,...

It'll be interesting to see what happens in the European Union now, given that these early results from Scotland show the Oxford/AstraZeneca vaccine...

We're now far enough into the Covid vaccination roll-out that we're beginning to see real-world vaccine effectiveness data. (Effectiveness is almost...

There were minor contributions from the space setting--the "emotionally repressed astronaut" was already a trope, so the nature of Pitt's character...

Well, the idea is that she's not actually sociopathic, but acting out self-destructive impulses as a way of punishing herself for a certain event in...
