Whatever you've been doing during lockdown, you better stop it right now

WTF?

I was with you right up to 'Chinese dickless wonder'

The Honor MagicBook Pro looks nice, runs like a dream, and isn't too expensive either. What more could you want?

Re: Decimated

Accordig to wikipedia: Plutarch describes the process in his work Life of Antony.[7] After a defeat in Media:

Antony was furious and employed the punishment known as "decimation" on those who had lost their nerve. What he did was divide the whole lot of them into groups of ten, and then he killed one from each group, who was chosen by lot; the rest, on his orders were given barley rations instead of wheat.[8]

Mike137, I have no a clue either, judging from the responses we must be Mallory Valdemort, but Shirley and Ashley are probably some rightpondian for Alice and Bob.

Re: Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

You are correct a H molecule is lighter than a He atom, so the H2 sound speed is greater that of He by a factor of root. Diffusion on the other hand depends on 2 materials and their state. So for example, in air H2 has a longer diffusion length than He. It turns out that the molecular diameter of H2 is slightly larger than that of He, 297 vs 258 (picometer) [1]. Because He is an nonreactive noble gas the diffusion of He through a solid material barrier is much but much greater than the molecular diameter would insinuate. "At 512°C the rate of helium diffusion [in silica glass] is approximately 45 times that of hydrogen, and it is believed that chemical forces delay the progress of the hydrogen molecule through the silicate network"[2]

Re: Asteroid Ahhhhhhhhh......

...weponise approaching asteroids....OK. fine,

but what happens when we discover the enemy is us.

Interesting : ".... lots of small masses in a relatively small region... which was the real 'planet nine'..."
