Phlebotomist? (a person who draws blood, like when donating)

They didnt go anywhere, we just happen to get 3 good ones close together. 3 good space movies in 3 years is huge for the genre.

Your capacitor is not this, but here is some fun information... In the EU, if your capacitor meets these criteria, then it is classified as "dual use" and possession/use/manufacture/sale is strictly controlled, due to their utility in building components for nuclear detonators: High energy storage capacitors as follows: N.B.: SEE ALSO 3A201.a. a. Capacitors with a repetition rate of less than 10 Hz (single shot capacitors) and having all of the following: 1. A voltage rating equal to or more than 5 kV; 2. An energy density equal to or more than 250 J/kg; and 3. A total energy equal to or more than 25 kJ; b. Capacitors with a repetition rate of 10 Hz or more (repetition rated capacitors) and having all of the following: 1. A voltage rating equal to or more than 5 kV; 2. An energy density equal to or more than 50 J/kg; 3. A total energy equal to or more than 100 J; and 4. A charge/discharge cycle life equal to or more than 10,000; Ref: Regulation (EC) No 428/2009 http://trade.ec.europa.eu/doclib/docs/2010/november/tradoc_146860.pdf (skimming that document, I learned the term "splat quenching", that was fun )

Ok here's a hypothetical. Is this at all possible? 1 planet has a moon. Moons orbit is synchronised with the orbit of the 2nd planet, keeping it perfectly eclipsed all of the time. This is not stable due to n-body considerations. But perhaps it could be stable for civilisationally-significant periods of time? It would only have to be in place between the invention of telescopes until the day you want the big reveal, maybe 500-1000 years? Eventually this orbital arrangement will slowly fall out of synch, and at some point, somebody will notice that there is a planet up there! And soon after, civilisation. Perhaps the planet is remembered or mytholigised from ancient/pre-history (the last time it was uneclipsed).

Ohhhh, its the call of duty thing where "press F" did everything. I get it. https://knowyourmeme.com/memes/press-f-to-pay-respects Here's to Stan, who lived his best life.

I believe he has pre-recorded them for the 2019 releases. *** What is "F"?

Tidally lock the planets, put habitable land only on the far side of one of them. Even with shipping possibly travelling the far side, it would be a long time before another civilisation could be confirmed by either party. Sudden reveal: space travel, or more likely now that I think about it, radio communications (did that come bout around the same time as the electric light?)

FunFactTM: MiG-31 speed is limited by airframe heating to just below Mach 3 at altitude. There is a documented instance of a pilot escaping a SAM just by pushing the throttles forward past the redline, exceeding M3, but only briefly. I think the MiG31 is what is know in the biz as a "hot ship" (Mind you this was back in the day, in modern times, heavy SAMs can have "no-escape" volumes that extend almost to space and into the hypersonic realm. For many of the most advanced, the only difference between the SAM, ASAT and ABM variants is the warhead/guidance package)

Average lifetime is 15minutes, half life is 10mins. True, but the price tag reflects the hi-fidelity nature IMO, its a bit more serious than a "game". I was nervous about buying it too but got 60hours out of it in the first week! I believe it is the successor to the "Harpoon" series of sims.

Do you mean, could a better program have compensated for a bad sensor? Only if it knew it was bad, which would require another sensor. If that sensor is bad, then we are back at the beginning. *** Was chatting with someone about this the other day and the 737 MAX is not fly-by-wire (not fully anyway, spoilers are FBW). In other words, the autopilot does not control the aerodynamic surfaces, it controls the stick/yoke in the cockpit, which controls the surfaces. So if the autopilot gives bad commands, at any time the pilot can just grab the control stick/yoke to override. This makes me think that the "aggressive" or "abrupt" dive (as described by boeing) was SO aggressive that the pilots were prevented from taking this simple remedial action. And thats quite a violent error. Unless Im missing some key piece of information.

No, not much. It wouldnt have time to melt significantly and would act like a solid body of low mechanical strength. I mean yes, some outer layers would be vaporised, but that is the same for rocky bodies too, just with an icy body a bit more. Generally, when a large body enters the atmosphere it goes something like this: Due to extremely high speeds and drag, entering the atmosphere is like hitting a brick wall, but continuously. This puts extreme stress on the body. Its slowing down all the time, but due to very high initial speed (10-70km/s) it doesnt slow down all that much. As the atmosphere thickens with decreasing altitude, drag forces ramp up very quickly. At some point, the body will break/crack/shatter. This vastly increases drag as parts split apart (by vastly increasing aerodynamic cross-section, especially if it breaks into a great many pieces) dumping a great deal of kinetic energy into the air as heat. This can happen so rapidly and completely, that it resembles an explosion, often of multi-megaton proportion. All of this can be observed in all that great footage of the Chelyabinsk meteor. A comet has much less structural strength than a rocky body, so those phases will occur at higher altitudes. The larger the body and the stronger the body, the lower down into the atmosphere it will penetrate before exploding, and bodies of sufficient size/strength can impact the surface. Small bodies have much better strength/size/drag force ratio and can slow down to terminal velocity (so-called "dark flight" as it is now moving too slowly to glow or leave a trail) at altitude before drag forces get high enough to destroy it, making it to the ground intact, this will be slow enough that there will be no significant explosive effects at impact, like a rock dropped from a skyscraper. Newtons approximation for impact depth (https://en.wikipedia.org/wiki/Impact_depth) can be used to estimate depth of penetration into the atmosphere. Just knowing the size and density of the body can give you a decent idea. This approximation is very useful for any impact where kinetic energy >>> chemical bond energy (Im not sure of the exact numbers, but this starts around Mach 3-5) Penetrating our atmosphere to the ground at very high speed has been compared to piercing approx 6 feet of steel (if that helps to understand why some bodies explode) based on depth and density, per the above.

An antiBH would be indistinguishable from a BH. A antiBH+BH merger would be indistinguishable from a BH+BH merger. No energy from the annihilation can escape the event horizon. Behind an event horizon, energy and mass is indistinguishable. A BH can be created (hypothetically) from EM radiation alone.

FunFact: A lone, free neutron will spit out an electron leaving behind a proton, with a half-life of about ten minutes.

Way to bring it! Those guys are stone cold pros. ***

Nah, I want to focus on the videos, not just songs you think are cool

Im going to unashamedly fanboy on something. It sounds ike you would get a kick out of playing "Command: Modern Air/Naval Combat" ["CMANO"]. Its a hardcore military strategic/tactical sim and can model all of the things you are talking about here in as-close-to-hyperrealism-that-unclassified-data-can-get-you detail. Graphics are bare bones but utilitarian, but its the unit database which is the goldmine. I'll leave you to follow that rabbithole, but suffice to say, you can wargame all of these scenarios with real world (and some hypothetical/experimental) units. It tries as hard as it can, with the data available to civilians, to model every piece of equipment as closely as possible. A warship, for example, will have all its sensors and weapons modelled - in addition to multiple radars, sonars, IR cameras, VLS missile banks and heavy guns, down to the .50cal anti-speedboat guns and a guy on the bridge with binoculars. It is accurate enough to give you a pretty good broad-strokes idea of how various conflicts would play out in the real world. It has its limitations like every - but its the best, most accurate one on the market (and yes, they do provide a "special" version to military customers) Oh and yes, it has midget subs. You can do fun things like install railguns on battleships. It models everything from an infantryman with an AT missile to ICBMs and ASATs. It tries its hardest to include every unit from every country from 1940 to about 2040. And it does quite well.

And just because the internet: Banana pedals https://www.banananaeffects.com/

I think it might almost be automatic. I think I'd whisper if someone told me a mahcine with the most sophisticated listening equipment in the world was looking for me to kill me, I'd whisper no matter where I was! Its like, on the TV, you always see people duck when entering a helicopter, like their heads might get caught by the blades. But the blades of an average helicopter are like 8-10 feet off the ground, minimum, right? So why duck? I've been lucky enough to have a few rides in a heli, and by damn, with a 500hp gas turbine spinning 10 foot blades above your head, you freaking DUCK!

FunFactTM: Humans share 50% of their DNA with bananas. For real.

I have heard anecdotally, that the hull of a submarine (being about 2 inches of steel - and on top of that, various other noise reduction measures, like those rubber tiles) is quite soundproof to normal noises like talking or walking, but that submarines that are trying to hide will still have "run silent" procedures that involve keeping any internal noise to a minimum (eg: no running, no shouting, stow things like tools or other loose objects, turn off the dishwasher etc.).

What is it in human male DNA which makes hyper-accurate rolling stock seem so cool? (Its not even my hobby)

Not even slightly, every facet of nature and biology fits exactly with the principles of chemistry and physics. Its just extremely complex is all, hundreds-if-not-thousands of co-interacting reactions, processes and cycles. In a drop of blood or a gram of tissue, there can easily be 1000s of distinct chemical species, but they all obey the laws of physics. "Because we're alive" might seem like a mystical, romantic answer full of mystery and intrigue, but those words express a specific set of chemical/biological circumstances that exactly describe why the body decays. Now, it might take me several pages and hours of writing to properly describe why a body decays, but that is because its complex, not because it is not understood. That is not to say there arent things we know less about, in the life sciences, but in all cases the usual scientific method works perfectly well.

Dude, one day you will look back and wish to all that is Holy that your work was as simple, easy and worry-free as that homework
