i learned the topological cohomology of the punctured topological neighborhood of a singularity on a complete intersection variety over the complex numbers, equals the etale cohomology of the spectrum of the henselization of the local ring of the variety with the maximal ideal removed. (This was a conjecture I had generated to attempt to explain a remark Mumford made about the first example he gave of a prescheme, something I am trying to learn by reading his "red book" of algebraic geometry.)

Today I learned that a three feet drop to the floor does not necessarily destroy a 3 TB external hard drive.

Don't be so sure. There may be just a tiny flake off the disk somewhere but it only takes one to start a failure cascade.DennisN said:Today I learned that a three feet drop to the floor does not necessarily destroy a 3 TB external hard drive.

If it was powered off at the time you have a fair chance of no damage. Of course it all depends a lot on the surface it hit, in what orientation, and from how high.
If it was spinning, copy everything immediately, even before doing any tests, and use it only as a scratch disk. If you continue using it, you may want to run full-surface diagnostics on it occassionally over the next few hundred hours of running time. Do not count on the self diagnostics or error reporting, they are useful for tracking the wearout of the drive but can not be counted on for early head crash detection. I've even had "Factory Refurbished" drives fail full surface scans when the built-in self test shows a practically new drive.
Good Luck!

Thanks a lot! Now I got a bit nervousTom.G said:Don't be so sure. [...] Good Luck! Tom
Edit, HDD Fall Info:
Landing surface: Wood floor
Powered on or off: I don't know. It was on, but I pulled on the power cord itself. I think the HDD was probably on when it hit the floor.
Spinning: No, I don't think so.

Today I learned that Admiral Villeneuve, who commanded the French/Spanish forces at the Battle of Trafalgar to a devastating loss, was captured and returned to France after giving his parole. He died on his way back to Paris from six stab wounds to the chest, recorded as suicide.

Today I've learnt, no better, I have just found and can't still close my mouth over this surprise.
First a language problem. I was looking for an English term. Google translate gave me "tease", another dictionary had "sobstuff", "tear jerker" and now it comes: "schmaltzy song". WHAT? They really transported this into English? Unbelievable, however, better than Blitzkrieg.
Now as you know what it's about, namely one of the most "schmaltzy songs" and the most famous grammar mistake in German music history, you can imagine what kind of song this is. And ... I've just found a version from Metallica! Incroyable! And the worst of all: neither transformed into heavy metal nor translated into English.
How about adopting another word: fremdschamen = feeling ashamed but for the deeds of strangers.

Today I learned "SpaceX will try to bring rocket upper stage back from orbital velocity using a giant party balloon and then land on a bouncy house".
Theoretically sounds outlandish, giant parachute could be possible? Lost on bouncy house.
Goodnight everyone.

Not the upper stage, just the payload fairing. Here is an image of it, it has two halves around the payload to protect it in the atmosphere.
The "bouncy house" was an earlier concept that didn't get realized. The default option is now a big net on a ship. The ship is not available this time, so they will just land it softly in the water with a parachute.
Edit: Just saw the tweet. Unclear if that is a joke...
The second stage will deploy the satellite in a highly eccentric orbit, not very suitable for bringing it back in a controlled way. A balloon to speed up deorbiting? I can imagine that.
Edit2: Look like this statement is for missions after TESS.

Blitzkrieg, btw, is a Metallica song. A pretty good one for workouts.
What song were you looking up? Maybe (their cover of) Turn The Page?

Funny fact: Although the misplaced and removable "c" has survived the conversion, there also has been inserted a new "t", which doesn't exist in the original. Strange. The literal translation would be greasy.jim hardy said:So, what schmaltzy song were you describing ? Teenangel ?
None of those. It was a German song, sung in German and basically with the original arrangement, i.e. not made metal, which also exist. I would link them, but I think there have been copyright issues, which is why we had to close the music thread. "marmor stein und eisen bricht heavy metal version" should bring up the list on youtube. And "bricht" is grammatically wrong.StoneTemplePython said:What song were you looking up?

Btw., Schmalz is also (rarely) used as a synonymous for money, esp. when it's used to make things work (= oil), i.e. for corruption.jim hardy said:language is fascinating.

♪ Marmor, Stein und Eisen brechen, ♫ aber unsere Liebe nicht. ♪
Nope, doesn't work (grammatically correct, but doesn't rhyme any more: Marble, stone and iron will break, but not our love).
♪ Marmor, Stein und Eisen brechen, ♫ lass uns Liebe besprechen. ♪
I'm not convinced (grammatically correct, rhymes, but lost the message: Marble, stone and iron will break, let's talk about love).
♪ Marmor, Stein, ja, alles bricht, ♫ aber unsere Liebe nicht. ♪
That would work: Marble, stone, well, everything breaks, but not our love.

What's wrong with Blitzkrieg? It's literally "lightning war" and means a rapid assault, too fast for your enemy to get their defences deployed to meet it. Isn't that its original meaning? Or are you complaining that it's also shortened to Blitz and used to describe the WWII bombing campaign against Britain? I agree that's a misuse of the term as I understand it.fresh_42 said:Unbelievable, however, better than Blitzkrieg.
We quite happily steal words from other languages - schadenfreude and zeitgeist are well known, even if not exactly used every day.
