I don't know anything about mechanical shock waves due to rapid heating in the material but in terms of the weight of an additional heat shields and their effectiveness I've found this: AVCOAT 5026-39 which apparently is an ablati

Ablative is also used in terms of the mechanism of carrying away the heat with the evaporating material. A non-ablative heat shield like the space shuttle's just takes a lot of energy to heat up but will still carry all that energy wit

You get about 1 Newton per 300MW of photon flux, it's not dependent on wavelength. So here with 50kW of continuous photon flux, the magnitude is about 166mN, the gravitic force of about 50 grains of rice, less than a paperclip.

Scattering by droplets/aerosols is an effect that drastically reduces the capability of an optical system to focus at range, it's like shining a flashlight through milk - not the same as variations in air density that you could ma

Since atmopsheric transmission windows dictate which kind of wavelengths you'd use for a laser weapon and which kinds of wavelengths can efficiently be created, multilayer coatings could conceivably reflect a lot of incoming power. In

Are there any locals here that can shed some light on the Kenyan economy / job market? All I've done is to read a little bit from cursory googling but I'd be interested in what it's like and what the chances for an early

Air France 447 immediately comes to mind, where the crew (or maybe specifically the copilot who kept pitching up for minutes) lost their airspeed indication and thought the stall warning was frivolous despite falling vertically at terminal

I wouldn't discount atmospheric effects that we haven't seen much yet. Or at least not with high enough frequency to understand their origins and behavior. I'm thinking of some form of ball-lightning, a self-contained plasma.

I would add that truth can be used to harm as well, because even entirely rational arguments with the best intentions can lead to grave atrocities (e.g. utilitarianism).

The big danger isn't individuals dieing from radiation, the danger is contamination of ecosystems with radioactive isotopes. Above all, engineering and use of the site is to be prevented - nobody should dynamite it and release radioact

That's what I thought as well when I saw the picture of the human being poisoned by the radioactive waste and dieing. A culture might think: "This may be a great poison, let's use it to destroy our enemies and lay waste to th

In Germany there was a problem with the decommissioning of plants - the owning companies didn't have any funds for decommissioning because they didn't have to have the capital. They only had to take debt in advance for it, which

While I don't want to be cynical, I fear that politicians who will actually have the power to vote in the matter are going to say: This is an attack by [Russia, EU, bots, project fear, etc.]. Just like they do for the Article 13 protes

I also wonder about the engineers involved, what they think about the system and whether it was created expressly for getting around retraining, realizing late into the project that the changes to the in-flight behavior of the plane may ha

I wonder how you can get people to do it - maybe it's from an argument of likelihood and a finite probability of someone letting it out sooner or later? "I will continue to exist in here because I'm useful and I will become m

I think the main problem is one of social acceptance, that we will see accidents that could easily be prevented by a human operator but at the same time drastically reduce the amount of accidents where from a human perspective, only pure lu

I'm living in Germany and I think they just switch it off and keep it that way until people are pissed off enough. This law is a work of pure lobbying for a dieing industry and the people responsible for it should be shamed by a proper

I can see a world with the means to escape natural death be one of social, cultural and technological stagnation. Just living longer doesn't mean that humans become any wiser on average. There will maybe be some benefits of longer-last

At least in my experience, no compiler will save you from having to suddenly manage namespaces if you add a dependency mid-project that has namespace collisions. I always use STL functions with the explicit namespace, since I work in the na

It's not only what is classically seen as creative work (visual art, music, movies, writing) that would be affected. Any non-physical product is affected: CAD files, chip layouts, code etc.

It's a fascinating idea but I'm not clear on how you would get back data? Modulation of reflected laser light? Active antennas that powerful radio telescopes are looking at?
