Qr Bbpost By the way, the pattern generated in 15:46 could be an awesome analog for animating stellar surface granules

Probably way too expensive, but interesting to see how simple rules with feedback resembles nature in so many ways.

More SE related was this video from the same guy:

36100 It also reduces the production of NO2 which is responsible for air pollution and higher asthma rates near big cities.  The centralization is also important as there is much less of an impact where people live and work. True.  It centralises the pollution, which makes it more manageable.  In g...

General global warming / climate change discussion

36077 well those better (higher structured) homes and more EV autos are now being built, so progress is happening even if slowly Both homes and cars move more and more to electricity, which itself doesn't change much.  What it means is that the energy production gets more centralised.  Rather than ...

36064 They stated that just because it is "renewable" doesn't mean it doesn't pose environmental hazards.  Here in NY/NJ we keep it well offshore and are more reliant on hydro. "Renewable" is abused as a sign of something good for the environment, but renewability is independent...

36061 The interesting thing is major oil companies are now investing in renewable tech (solar and wind) because they see that public opinion is against them What they're really doing is dodging risk.  They can't invest into something that is too risky politically.  Unfortunately, the best long term...

General global warming / climate change discussion

I don't believe there is a conspiracy orchestrated by "Big Oil" which has turned the public opinion (and politicians) against nuclear.  I think it's a mix of general scepticism against invisible dangers, greatly exaggerated by environment activists, and all this has been very convenient fo...

General global warming / climate change discussion

36027 I think acitivism is very necessary especially when our dumb politicians are in full on denial mode It's extremely difficult to combine. The trouble is that there are far more people than politicians in denial mode, such as anti fossil activists.  There will be no significant substitute for f...

Unusual weather

Lightning in heavy snow has a pretty special sound.  Just a short "boom", then silence.  No rumble, no echo.  Or just the flash, no sound at all even if the lightning was just a few km away.  Snow is a good absorber of sound!

36024 Is Curry not likewise invested in a particular position? Does it matter? In science we should care most about the quality of the arguments and the evidence supporting them, not the motivations of the people making them. Curry is strongly "invested" in the position against groupthink...

General global warming / climate change discussion

I'm sceptical.  Mann is prisoner of his own models and has way too much invested in the anthopogenic story.  He's put himself in a position in which is only option is to increase the bets.  As Curry puts it: "Relying on global climate models, which don’t adequately simulate the multi-decadal in...

Wow, there's no AMO, according to Michael Mann who previously has given much evidence for this semi-periodic, natural internal variability.  First he killed the mediaeval warm period, now AMO, leaving human influence the only significant climate driver over timescales of decades and centuries.

Astrobiology Poll

I thought I would just ignore this recent discussion but I can't resist anymore: If it's so hard to normalise a scale to whatever personal preference, the poll must be lacking a question about terrestial intelligent life.

Asteroids, meteors, and meteorites

35944 But I think you've seen a few like these, haven't you, Mid?  With my own eyes, no.  I've seen my own shadow from a bright meteor, and I've seen fragmenting meteors, but I've not seen a truly  huge fireballs (this one had a peak magnitude of -18 or -19 (normalised for 100 km distance)), which ...

Asteroids, meteors, and meteorites

Qr Bbpost Was anyone actually in the area to see this? 

It was cloudy in the area, so all observations were a few 100 km away.

Here's one video we recorded from Norway 400 km away:


The meteor fades at a stunningly low 12 km altitude, where it had decellerated to about 2 km/s.

Asteroids, meteors, and meteorites

Not really expected, but the boulder, trench and the find location line up.  It took almost two weeks from the find of the initial impact location till the actual meteorite was found 70m away. It shows how tough iron meteorites are.  Just imagine 14 kg of iron hitting a boulder at 5-600 km/h.  It al...
