'MarsHelicopter, you are cleared for takeoff. Flight commands are being sent.' https://twitter.com/nasajpl/status/1383837131110420488 ...

I have a similar book called the Passion of the Western Mind, by Richard Tarnas. A history of philosophy. But it does not deal with Chinese...

I am also fond of woodworking, but I haven’t tried making boxes yet. So far, I am making products simpler. Recently I ordered a Bosch woodworking...

Not sure why you are fixated on this - your math is simplistic and filled with assumptions and figures you don't give references for. It is a...

I was thinking the same thing, and no doubt NASA teams have thought about it and modeled it, but Ingenuity is designed to be light and it does have...

:rofl: I know others have commented on this, but after all this discussion about the ubiquity of radioactive substances, I’m impressed and...

Sitting for a few weeks shouldn't be a problem; the helicopter is capable of recharging itself as it needs to do after every flight anyway. I...

I have to admit that while I 'knew' that the Classics were rediscovered in Europe via the 'Arab world I didn't realise how important the writings of...

Ironic to see you saying that. A science article you provided showed you to be wrong, but you have yet to acknowledge it. You’ve been presented...

Ah, yes, dismiss, disdain, and disrespect. Your fallback position when you have no answer is to go on the attack.

You most certainly did not! I even quoted that entire post in my response in #306. In fact, in #227 you claimed: You have not provided one bit...

Remind me. Did you check my math?

You cannot expect the blind to see or the deaf to hear.

You seem to forget that you alone bear a burden of supporting your position. So far you’ve not come close to meeting that burden, so the default...

I've always been interested in history and philosophy, in my own amateurish self-taught way. I have read a few of the "Classical" writings of Western...

It must be hard to argue using factual information too, because you haven't been so far. Others managed it here, so maybe it's not so hard after...

Why, what do you have? 'Cause what you've shown so far fails to convince anyone.

Why not just look up the observations from multiple sources? Those things were widely tracked by telescopes all over the planet. Even from the Soviet...

I guess that settles it. It is hard to argue with a banana.

Is this the sum of all that you have? Really?

That’s pretty absurd, Lord Foul. Have you ever eaten a banana? If you have, then you have violated your own prohibition. “The dose makes the...

I don't know if you guys observed this but Bob B. calculates the Apollo 11 dose for a lunar transit to be 32mrem. Bob B: Based on my analysis of...

Just a thought - there are now thirteen separate Director’s Keyboard threads, and they are weekly. Within a year there would be 52 more. They are...

So this is the Bob B. VAB proton map you guys want to defend?

I have just finished "Awakening - A History of the Western Mind AD 500 - 1700" by Charles Freeman. It was not a 'fun' read as it comprises some 741...
