For Krogh, the source of the number, it was a quite reasonable estimate, which was about all that was possible at the time. And it was ‘wrong’ by less than an order of magnitude … compared to the newest estimate. AND an estimate of a truly unimportant number is as good as you can get (or need) in many cases. What’s the total length of all the ice cores drilled since Camp Century? And their total volume is?

Sabine is a very competent physicist. That’s why her viewpoint - right or wrong - is well worth hearing. The fact that the Nobel went to a computer scientist instead says a lot about the state-of-the-art.

Sabine knows her shit. May she coax some physicists into getting back into experimenting… and away from Big Science funding.

Here’s a picture of it while it’s still in the shop. https://inspenet.com/en/noticias/nasa-tests-solar-sail-in-solar-in-orbit/

Haven’t heard about the NASA design yet, but JAXA’s 2010 IKAROS used "Eighty blocks of LCD panels are embedded in the sail, whose reflectance can be adjusted for attitude contro ".

Great film… and nobody but Robin could have done that scene so well. Phew.

Yeah! Did that once, many years back. took a couple weeks. Used a ripper program that went out on the net and got all the metadata, saved to a HD (now on the third one). Put the CDs in Logic cases (no-wear), recycled the jewelboxes.

Over time, started to drop album folders into VLC, save the playlists, at ur fingertips.

Fork them.

Yeah… well (we have to admit) the ‘hole’ quantum part was very long and VERY nerdy for a whole lot of people. (Their loss.)

Whoa! Thanks for the pointer, I never saw one. (Don’t get to HD much these days.)

Good idea! Also works for shortwave stations that turn on at your wakeup time, especially if you’re annoyed by propaganda!

(I use an FM radio tuned to a spot where there are no signals. Doubles as an FM radio during the day.)

(Use the tone controls for more or less white or brown noise.)

YES! I a roll recently to get the cables behind my desk up and away from my feet. (Jerking cables out of their jacks sideways is bad for today’s crap hardware.) AND no more rats’ nesting.

(Too bad I never found a desk with a cable gutter along the back. Wud be great for a bunch of heavy audio/midi cables.)

Really good science news communicators (including many teachers because how are admins to judge?) are too rare … on YTube there’s … a half-dozen, maybe, at best?

" the Selfish Gene, which I could rip on for pages "

Please put me on the list to read that!

Yeh! Good to see the rusty machine (and self-deprecating) model fading away and being replaced by real appreciation of the true marvels that have emerged over millions of years. (Science’s mechanical models were all so … 18th century!)

(Not so familiar with biology but did enjoy hearing about the tack Lee Cronin’s taken.)

No, it isn’t … although batteries are getting cheaper there are far cheaper ways. But they’re too practical, and the game’s still about big money-making while the political heat is growing.

Dinty Moore still comes in cans … and is better than ever (esp. compared to most of today’s canned “food”.

Strange to see people blaming their fellow citizens, when it was a certain beloved King that started off his reign by hugely cutting the tax-rate of corporations, leaving them with the ‘trickle-down’.

Somehow rulers manage to keep the people divided by keeping them blaming each other rather the root-cause.
