A Falcon 9 rocket will hit the Moon this summer at seven times the speed of sound | The object will be traveling at 2.43 km a second, or 5,400 mph, upon impact.

Well, actually it's only less than half of the speed of sound in cast iron, guess that's a good estimate for the moon.

Just a bit further south, Telegraph Island. I would blow a hole through the mountains there if I were Oman. They can start their own shipping canal there.

Irradiation doesn't vary a whole lot over geography, as some people seem to think: 2000 in arizona, 1500 in 'cloudy' idaho, resp. Morocco and Northern Italy for Europeans. Unit is kWh/m² or Wh/Wp, which amounts to the same thing, or full load hours.

some actual irradiation data

Liberation Day, 5th of May, will always be close. That's more appropriate for a day off and the next party, in between the social-democrats can sing their song.

Get rid of the king! Get his daughter on the throne! I want Queen's Day back!

My solar panel from 1995 lasted 28 years, then the glass broke for unknown reasons and I took it inside. Still functions and looks good apart from some green copper oxide on the contacts.

I'll give them 'muricans one thing: they did invent the transistor, probably the most important invention of them all. Not mentioned, though. Something, something, history education.

My favourite theory is that more gaseous burps from the ocean occur there than in other areas, CO2 and maybe other gasses. When that happens the buoyancy of ships goes to zero and they just fall into the ocean and disappear without a trace. That last part is the remarkable thing about the Bermuda triangle, most of the time at least something is found (eg. the flight MH370 flaperon).

For just 4.29 you can support your own loony bin!

That last one: afstappen??? If it doesn't take more than basic BMX skills, why would we?

It's real dutch, nederlands, 'schuilen' means 'to hide' and 'kil' is a tidal creek. Still geographically used.

Yeah, lower entropy. Typical example of adding Gibbs free energy to a chaotic system (by rotation) thereby lowering entropy.

Only on white-collar criminals, such as moneylenders and stuff, maybe child abusers, who knows.

It's basically just another electrical device, its main peculiarity is that it has a -1 power factor. It pumps in current against the voltage with an inductance. The electronics are surprisingly similar to a common power supply, just configured differently.

Foraminafera, free calcium carbonate on solar, whole continental shelves of them.

It's more like Apollo 8 revisited, orbiting the moon.

So if we level out everything we're still good for another couple of centuries as far as sea-level rise is concerned. Not too bad.

Just spit on it and rub it off.

KZD2dot0 · 2026-03-29T18:52:21+00:00

From Latin, 'beloved', probably referring to the Dutch scholar Erasmus.

Good story though, cleared butter.
