kalkulat@lemmy.worldto Ask Lemmy@lemmy.world•What book did you read last and what book are you currently reading? Would you recommend either of those books?English2·3 days agoListened to the audiobook version of Cryptonomicon by Neal Stephenson. I’d read it long ago and was surprised how differently I experienced listening to it. Recommended.
Currently finishing a read of the (British) Rough Guide to Cult Pop (2004) … a book about pop/rock music and its makers from the 50s forward to to 20 years ago. Broken up into many sections, put together by a crew of Brit-wits, many interesting facts and stories about a half-century of chart hits. Strong recommend IF you’re into that sort of thing, appreciate a bit-o-snark, and know most of the names already (or want to).

(Altho he has confidently misstated the facts a few times.) Sabine definitely has her on days and off days. Maybe I missed her saying exactly those two things you put quotes around. As for the productivity of Big Science, I think she’s right to suggest that it has not delivered the way that it once did, and right about how many of its top-rated people have lost its way (while there are still small, almost daily discoveries being made). (HYUGE topic for this little container.)
That’s only one and a half-assedtrophysicist.
But yeah, that was a great discussion.

I don’t think Jules Verne thought of it (haven’t read all his stuff), but it might have been Aristotle for all I know.
kalkulat@lemmy.worldto Videos@lemmy.world•Sabine Hossenfelder Has Started Openly Defending Proven GriftersEnglish3·6 days agoSabine is a very bright and well-informed lady. I enjoy listening to her trash the well-paid real grifters. They’ve started attacking back? That figures. I guess hearing that you’ve been under-performing for decades makes it hard to stay focussed on the string theories and the ‘new particle!’ theories.
Nope. I chose to go to school and paid to get educated, not to get grades and piece of paper. No cheating, no cramming … I would only have been paying to cheat myself.
kalkulat@lemmy.worldto science@lemmy.world•Why the federal government is making climate data disappearEnglish5·6 days agoThey can make the data disapppear, but they can’t make our own experiences (or the weather news) disappear.
Where I grew up, every year the winter temps got down to where F and C are the same temperature. That stopped happening 15 years ago, when temps in the Arctic had climbed fastest. There’s plenty more evidence out there, from all directions. They’re hoping that we’ll start to distrust our own senses? We can live underground, but that’s a hard place to grow food.

Discussion here sez it takes a radius of 224m at 2rpm: https://space.stackexchange.com/questions/281/what-would-the-size-and-rotation-of-a-station-need-to-be-to-produce-1g-gravity-f

Probably not fatal though… exercise left for the student.

kalkulat@lemmy.worldto Ask Lemmy@lemmy.world•Audiophiles, I need your advice. Looking for a mobile option for a bluetooth connected speaker that can play in the 20-100 hz range.English1·10 days agoSeems to me you’d be better off with a circuit that up-converts 20 to 100 Hz sounds by a factor of 20, putting them into a range you can hear. That would not have to be a complicated circuit, and no doubt they’re already out there.
Or it could convert sounds in that range into something that amplifies those frequencies and vibrates against your skin instead (a ‘skin speaker’) … probably easier to make than a converter.

kalkulat@lemmy.worldto Ask Lemmy@lemmy.world•What music do you consider to be part of your musical Shadow in the Jungian sense?English1·12 days agoA music lover since the day I was born … and I’ve heard it all … I’ve never heard any ‘dark music’ per se. If by music you mean music with lyrics, that’s different.
There’s no such thing as a ‘musical shadow’. Jung’s ‘Shadow’ consists of psychological parts (‘garbage pit’) you’re not aware of because you’re hiding them from consciousness (for various reasons). What ‘you consider’ isn’t a part of it.

I might not install that -exact- version (prefer to install where I can easily back things up).
kalkulat@lemmy.worldto science@lemmy.world•Fossil discovery in Greenland ice stuns and worries scientists: "Don't buy a beach house"English1·14 days agoOne -possible- different past. Of course, we may be wrong about what caused it to be much warmer -in Greenland- -at that time- .
One simpler example: the Earth’s North polar axis may once have farther from Greenland. Plate tectonics has made this a much different planet than it was 200Million or 400M or 600M years ago, and there was possibly a time when Greenland was much farther from the pole … and had no ice.
Or (if Charles Hapgood was right), much of the Earth’s crust may have shifted it’s position (think an orange-skin no longer firmly attached to the orange) over, say, 100,000 years or so.
kalkulat@lemmy.worldto Ask Lemmy@lemmy.world•How do you know you're actually reasoning - and not just storytelling?4·15 days agoIf your reasoning is entirely based in evidence available to everyone else, that’s about as trustworthy as you can get. The less people know about it (or the more they’ve already been misinformed about it by people they -did- trust), the more likely they will not follow your reasoning.
That, for example, is why it took Tesla years to get anyone to help him build the first AC motors and generators … including Edison. Most either knew little about it or were already convinced that it couldn’t be done.

I’m certain that she didn’t mean that -all- fields of science were scams … it’s always been physics that she’s PO’d at. And I understand that point 'cuz I’m very familiar with the history of physics, so I don’t need your recommendations. The position you’ve taken is clearly unassailable; I appreciate her news reports and chuckle at her sarcasm, so I guess we’re done.
