There's not much older than the Vasa that is essentially intact. The Vasa is in good enough shape to have been recovered as a ship, and not as a shipwreck or an archaeological dig, which is pretty remarkable. I think there's one O

> The Mycenaean palaces had developed a syllabic script, which we call Linear B, to represent their spoken Greek. This form of writing is entirely lost. In the 8th century, the Greeks will adopt an entirely new script – borrowing the on

Crew Dragon flew an automated demo flight before flying with crew. It was proceeded by 20 flights of Dragon 1 over 10 years. Starship's heatshield has already been tested full-up half a dozen times. Many changes have been made as a res

Belgian glasses, like wine glasses, leave room for head and aromatics. Belgium is also fanatical about matching the glass with the beer, and Europe has the very sensible pour line on glasses, so it is designed for a certain fill and filled

I don't see that Google cares much about backlinks any more. Seems like it's all about "content" keywords and maybe a little time-on-site. The domain is a huge signal, which is probably where the problem comes from here.

Industrial buildings are typically built at dock height. Even if they don't do any grading, that would put the building well above any plausible flooding in that area.

There is a problem with the number of dimensions. Even a t-shirt is described best in neck, chest, waist, and you could add several parameters for sleeves and also for heights. Neither consumers nor manufacturers can really handle the combi

"Plaster" can be lime, gypsum, or cement, in rough order of historical adoption. Sometimes you even use different types on the same wall; cement rough coat and lime or gypsum top coat, for example.

Because this is not about charity, but about politics. Specifically demonstration with the intention of advocacy. The advocacy falls down when the demonstration is less applicable.

The idea here is that the economics of launch are changing with Starship such that the "incredible cost" and "overspeccing" of space will become much less relevant. There's a world where, because the cost per kg is

It's a mid-50s bomber. The skin will be easy to replace. Drill out the rivets, rivet on new sheet metal. I don't think it even dragged the wingtips. Might be some complications with the nose gear and the payload bay (the main gear

I think the point of this headline is that they're not being blamed in this one instance.

That's not the sort of "regulation" in "deregulated energy market". Which was always a bad term. "De-integrated" would be better. It's a situation where energy generation and retail are separated from

Much smaller, no atmosphere. You can get a lot closer to it in orbit. Until Apollo 14, the LM would enter a 50,000 ft periapsis on the way to landing. Dunno the exact phasing of this lander, but that video could be from a similar height (or

Or they're using "surplus" resources (like their backyard, and domestic food scraps) that they'd still have otherwise. Which is something that is not commercially scalable. Unless, I guess, someone tries "Uber but f

Cute. But 3/16" is way too large a pilot hole for any reasonable screw. I think a #24 screw, which is the largest size of wood screw, has a 3/16" pilot size... and uses a #4 Philips, which is not the bit on this thing (a

This is impractical in the US as things currently stand; most utilities have a permitting process for a grid tie (anything that backfeeds the grid) and smartmeters are capable of detecting and reporting any backfeed. Mostly the technical as

Hugo voters are members of the World Science Fiction Society (who are mostly Worldcon attendees). Which is to say, voters for that are chosen for enthusiasm for the genre, not taste.

The "civil" here is as in "civil aviation". Aviation is broadly either civil or state aviation. Presumably it's derived from "civilian".

The former (terminating lines) needs more tracks/platforms at the station, because turning the train around takes more time than stopping and continuing (through running) and turning around at the end of the line.

ETOPS per se makes no sense for a 4 engine aircraft (the T in the acronym is "twin-engine".) Three- or four-engine aircraft have equivalent engine-out long-range operations ratings, though.

Starship itself will not be a great deep space delivery vehicle, in the same way current disposable second stages are used. Too big and too... reusable. However, it'll make a great delivery system for some serious high-energy escape ve

Well, Congress specified it to use SLS, since they were looking for extra payloads. And then uncoupled it from SLS when it became clear it couldn't even handle one extra payload. NASA, wisely, always benchmarked the mission on Falcon H
