Orbital rings like circular skyhooks that are much easier to schedule pickup on, and have much friendlier structural stress characteristics, seem not to be written about as much as they ought to be. If by orbital ring you mean a band girdl

They were, in fact, out of fuel and unable to operate heavy industry, and faced disaster. That the generals had personal opinions they were empowered to act upon did not change the objective fact that as a nation they could no longer wage w

A vehicle whose chief feature is that it can take off and land and be launched again not landing and being launched again tells us all we need to know. If it is just changing orbit while up there, it doesn't need reusability. Just laun

And pure thermal uses are not good storage for high-grade energy forms, e.g. electric, because of conversion losses. In Norway, pumped hydro is a good place to park high-grade energy. That said, for rarely drawn-upon storage, conversion eff

2 GPa is 2GN/m^2, or 200kN/cm^2, which supports 20Mg. Taking silk density as 1 g/cm^3, that is 20M cm, or 200,000 m, or 20km. Silk density is actually ~1.37 g/cm^3, so derate the above to 14.6 km. IOW, a silk cable can s

For metabolic syndrome, the first go-to is cutting sugar. Specifically, fructose-laden sugar. For many people, it suffices to eliminate sugary beverages, including juice.

This is an example of "how can we keep X relevant in a world where it is not?" Geothermal is falling away because maintaining a steam turbine is expensive. There are plenty of efficient storage options that don't depend on a

The operational uselessness of X-37 is demonstrated by their leaving it parked in orbit for months or even years at a stretch. Apparently they park it in orbit instead of a hangar to make it look as if it is actually "on a mission&quot

There are always more specific targets in an area that cause more trouble destroyed than others. Blowing up a playground when nobody is there has to be counted as a miss when an electrical substation is nearby.

Japan being ruled autocratically, their civilian resolve might not have mattered much. Blockade eliminating fuel imports had them ready to surrender already. The nukes were meant to scare Russia. But Russia already knew all about the nukes.

They do have other things they need to spend on. Russia is a net food exporter, but probably they do not grow all they need. Smuggling needed foreign tech, and laundering money, has to be expensive. Paying off internal supporters might be a

Curious about what was where it actually hit. Seems pretty clear Samsung was not the target. Electrical substation "across the street" would be a probable target, but was missed. I.e., did it hit a plausibly intended target, or mi

Report is that it struck 150m away. There seems no doubt it was Russian ordinance. So arguably we saw the report about the building just because a foreign property is there. Presumably whatever the missile actually hit was obliterated.
165.
by ncmncm 4y ago
Imputing rational behavior might be a mistake in this instance. But more likely, the actually intended target was something nearby, and we hear about Samsung because we (are assumed to) have more interest in Samsung.

Right, except for libraries or language-specific toolchain, the only legitimate reason to mention language in the title is to suggest doubt it was possible.

The key to all big projects that work well is that they start with small projects that work well, and deliver something useful immediately, adding more continuously. They don't need to stay with equipment they delivered at first; they

For us anyway. Doesn't mean neanderthals suffered from it. I.e., it could be just a neuromolecular incompatibility.

AFAIU, the only consistent difference in behavior identified between H. n. and H. s. is the former has never been found to have traded with outgroups. That seems consequential.

Seems to be we occupied more different areas, and so outlasted those with more limited range.

Genetic evidence suggests people got to the Americas about the same time as to Australia. That would have been by boat along Japan, the Aleutians, and down the west coast, maybe 50,000 years ago. Polynesians came along tens of thousands of

Sometimes. The replaced I-35 bridge went up fast. It would have cost radically less to maintain the old one properly.

Article misses the point that the cost and schedule overruns are really the whole point of the project. A project's nominal purpose -- train, tunnel, nuke plant -- is just there to fend off pressure to pull the plug. Sunk-cost fallacy

I seem to recall that they didn't declare victory until it hit 6 sigma. It always tickles me that a hedge fund is called Two Sigma. Who would want that on their CV?
