you're effectively compressing the fluid before you, and that compression pushes you back). In a dense medium like water that's overwhelmingly likely to occur, but in the ultra low density environment of intergalactic space I think you'll find that the initially incident particle is so incredibly unlikely to hit another particle in the timeframe involved that you'll get no rebound and thus no "drag". But you still have to worry about collisions, and at near-C speeds hitting even tiny motes of matter is going to be like being shot with a tank shell. Being shot by a tank shell has two demerits - momentum transfer (in this case you slow down a bit) and physical damage (it hurts). The solution, one your spaceship will need, is the same as employed by tank designers - a sloping hull. The more sloping the more glancing the blow, the less momentum you lose, and the less damage you take. I don't think Clarityfiend's concern about surface-to-vacuum would be a concern, because there's no need for that pointy "impact plow" to be filled with air or otherwise be habitable. It's a lot like the sea hull of a submarine - the submariners live in an ugly squat sausage-shaped pressure hull, which is surrounded by the elegant but unpressurised sea hull. SteveBaker's feelings regarding shielding are, however, I think well founded. Blasting around the universe at near-C is like being the projectile in a CERN experiment - all kinds of scary science impacts are going to be happening on the surface of the impact plow, giving off heat (in the plow) and gamma radiation and probably all that stangelet-blackhole-darkmatter disaster stuff that won't happen to CERN but will to you. So that's the front of your ship designed - it's got a super-pointy impact plow (maybe 2 km long and 100m in diameter) filled up with DU. After that there's a 2km pole at the end of which is your living module (where you and your chums live in a colour-coded-unitard utopia). Now for the back end. Let's face it, you're not going anywhere fast with those lefty-wefty renewable sustainable bussard organic macrame power sources; if history shows us anything, it's that to get anywhere fast you have to burn lots of evil fuel and leave a big mess. So behind your living module is another long pole, at the end of which is the propulsion module, wherein some faustian science horror occurs (bashing white holes into black holes, sacrificing bunny souls to Legba, etc.). Armed with this you can happily blast around the universe, and you can probably even bash on through planetary space, sterilizing the planets of impressed natives with the hard x radiation from your engines. Just don't try turning a corner. --

so some fuel pumps and fuel gauges that are immersed inside the gas tank will short out and fail. However, fixing those kinds of things isn't difficult. The most significant change that most engines need is to have their engine management computer adjusted (perhaps reprogrammed) to deal with the different mixture control you need in order to optimise performance. The biggest problem in Brazil is that their cars are generally poorly converted from gasoline to run on ethanol - and for some reason, their converted engines don't start well on ethanol. Hence most cars there have a small gas tank and a switch on the dash that lets you switch between gasoline and ethanol. So you put the switch into the gasoline position, start the engine - and when it gets up to operating temperature, you switch over to ethanol.

partially boil out and partially freeze - that depends on initial temperature and the final steady-state temperature). However, an aggregate of loose solid material may form a sphere at arbitrary low mass, if it remains unperturbed. That was not the original question. The original question was, as SteveBaker correctly noted, what is a smallest required mass for a compact but not spherical object with a solid surface at temperature of a few tens of Kelvin and density of a few g/cm to gravitationally produce enough internal pressure to be able to assume hydrostatic equilibrium. The inner parts of the object need not be solid in this process, though. They may be liquid or solid-liquid mixture due to residual heat, compression heat, radioactive decay, etc. --
2250:. Myo-stimulation is not uncommon, they have a weight-loss deal that does the same sort of thing, only from the surface. The difference is skin penetration, which will dramatically lower the overall electrical resistance. You haven't mentioned the proposed penetration depth or voltage, and we're not able to adequately judge either. Asking for controlled study ref's is bordering on medical advice, or at least opens the possibility of POV's creeping in - which is part of the medadvice stricture, really. You might be better to ask your practitioner for references from the Medical Review Board which approved the procedure. Get some good names and numbers, then we can search the heck out of it. 150:
memory. If we simulated a bunch of hydrogen atoms - those are just one proton and one electron - we'd have room for 21 million atoms. Sadly there are 6x10 hydrogen atoms in just one gram of gas. So we can simulate about 1/3x10th of a gram. You could store all of the particle data on disk - that would get you a couple more orders of magnitude...but certainly anything as complicated as grains of sand are completely out of the question! We could do similar estimates based on the time to do those calculations...I'm pretty sure the results would be just as depressing.

impacting particles. The space shuttle has similar issues on re-entry (it reaches ~8 km/s during the fastest part of re-entry), and the heat shield is specifically designed to survive the partial erosion during the trip. Incidentally, and in response to Finlay, the speed of sound in the galactic medium is "only" ~100 m / s. So to the extent that traditional drag matters in an environment with extremely low pressure, it certainly should start to matter before you cross the "sound barrier", though I would expect that drag would still be pretty negligible.
2516:. This may be learned/reinforced from childhood - if you show up covered in blood, your parents adopt a somewhat odd response, what with the screaming and "oh you poor thing" reactions. Evolution will also program you to be more aware of your own pain sensations when you see flowing blood, you have a compelling interest to be sure it's not your own. That said, I tend to get more supreme pain from paper cuts and that grass with the sharp edges (ragged cuts) whereas I've clean-cut myself to the finger-bone and been quite clinical about the affair. 2399:
also require agreement from all of the various different language WikiQuotes - some of whom have already agressively cleaned-house (eg the French and German sites). Getting cross-language consensus is a non-starter. The Wikimedia foundation lawyer has already weighed in with a statement that he considers all of WikiQuote to fall within "fair use" on the grounds that there are MANY commercial books of quotations that are not prosecuted for copyvio's - and WikiQuote is a non-profit which puts them even further from the law.

only be "evaluated" using various tricks. I guess there's an analogy with the calculus, which didn't get a rigorous formulation (the epsilon-delta limit stuff) until long after Newton successfully used it to do physics. But I think it's a fairly common view among particle physicists that the Standard Model will never be formulated rigorously because it really isn't rigorous—it's nothing more than a collection of approximation techniques (for the real, unknown physics) with no "exact approximation" at the core. --

because they were bouncing up and down under gravity at distances that were at the smallest that the computer could resolve. Those vibrations would "leak" energy from nowhere into the system and the whole pile of cubes would start jiggling and bouncing at large scales until the whole pile would collapse with no external forces being applied beyond simple gravity. We're getting better at fixing those problems - but it's generally via ugly kludges that show up under all sorts of subtle special-case conditions.

modelled as an indivisible particle. If you went down to the level of fundamental particles, i.e. quarks and electrons, you would be increasing the complexity by a factor of 100 to 1,000 (strong force interactions between individual quarks must be more difficult to model than the longer-range electromagnetic interactions between atoms). So probably around 1 to 10 million atoms is the upper limit for truly "first principles" simulation with current technology (which is in the same ballpark as
2076:, small amounts of cocaine are found in Health Inca Tea which can be purchased without a prescription. I guess that doesn't answer your question, but it's another way that benzoylecgonine might show up in the body. The article also says that cocaine is sometimes an ingredient for topical medications from ears/nose/throat doctors. Cocaine is metabolized into benzoylecgonine in the body, so it doesn't seem likely that benzoylecgonine would be a component of OTC medications. 1726:
as you'd expect - lying flat. As dust, dirt (and in the case of middens, decomposing food) comes to build up on top the pieces, the effect of making the shards horizontal increases. Where you see vertical shards is when the midden is so full of something dumped all at once that there's no time for each piece to "find its level" or where a larger piece has been broken

than the "fair use" bin! A compromise in which the fan-cruft gets nuked and new rules are set up to stop it from coming back are much more likely to get acceptance than simply wiping out years of work by hundreds of people. Something as simple as "No more than three quotes per film or TV episode." would solve 99% of the complaints.
741:, so theoretical predictions for the required mass may vary substantially. TNOs are also nearly impossible to optically observe with decent resolution, at least at the present state of technology, so we also do not know for sure which are round and which are not. It is, however, reasonable to assume, based on observations, that 937:
want to run your car on ethanol, you'll need to convert your engine. In Brazil, alcohol is cheap because of how much sugarcane they produce, so ethanol is available at most gas stations. I'm gonna guess that's not the case where you live, so you may want to stick with the gas/ethanol mixture from the pump. --

Don't take Clarityfiend's comment as meaning that you can just pour everclear in your car and go for a drive. Cars that run on 100% ethanol have engines that were designed to accept ethanol as their primary fuel. Gasoline engines can tolerate some ethanol in the fuel mixture, but only so much. If you

The other day as I was filling up my truck, I noted that the pump had "may contain up to 10% ethanol" on it. If I remember my high school science, alcohol burns cleaner than gasoline. So my question is twofold: first, what would be the optimum mixture of gasoline/ethanol to get the most efficient and

Sorry if you meant this to be a rhetorical question, but I'll bite. Ultimately, with or without cells, it's all chemistry, right? And it's all physics? However, when macromolecules are involved, interacting in complex ways we don't (fully) understand, it's generally called biochemistry, molecular

Most cars that claim to be able to run on Ethanol here in the USA are actually only able to run on "E85" - which is a mixture of 85% ethanol and 15% gasoline. I believe that E15 (15% ethanol 85% gas) is what we're currently limited to with "normal" cars. E100 is available only in a few countries -
959:
Ethanol produces a little less energy per gallon than gasoline - and in small doses, most modern cars tolerate it quite well. However, older cars suffer because ethanol dissolves rubber - which does bad things to rubber fuel lines. Ethanol also conducts electricity quite well (gasoline does not) -

The smallest "round" astronomical object known has a diameter of about 400 km. The largest object known not to be round also is about 400 km in diameter. (One is a moon of Saturn and one a moon of Neptune, I think - too lazy to look up their names.) So the minimum diameter seems to be around 400 km.

Regarding the "liquid body" suggestion - well, it is highly unlikely to find a drop of liquid in space, because it does not have enough gravity to prevent its vapor from escaping. Thus, the vapor pressure will be lower than the solid-liquid-gas triple point, and the drop will eventually boil out (or

is still spherical and is 950km across. So I suppose we could say that for a SOLID body - the limit is somewhere between 530km and 950km diameter - but for a liquid body, the limit is less than 530km...arguably, there is no lower limit for a liquid body because even a single water droplet assumes a

The tricky point is at that the kinetic energy these little particles release when they hit your starship depends on your velocity as well as their mass. So the energy of those collisions with the skin of your starship start to cause unacceptable amounts of damage - does that happen before or after

I don't believe that there is any speed you could travel at under which conventional compressive drag would occur (but see caveat later). For that a particle you hit has to rebound into some other particle(s) and then either it or they hit your ship again before you've moved out of the way (that in

Let's simplify this a bit. My computer has 2Gbytes of RAM - if we stored position and momentum to double precision for each particle - plus a couple of other bytes for particle type...that kind of thing - then we need 50 bytes per particle. So we have only enough space for 42 million particles in

It hurt more when I broke my arm (no blood) than when I popped certain zits (blood). Bleeding is caused by breaking the skin. Pain is caused by any number of different things, including burning, freezing, percussion, broken bones, pinching, etc. None of those would cause any bleeding, but they can

I get the impression that my brain is 'hardwired' to associate blood/bloodyness with pain. My question is: How good a correlation is it? If I cut myself shaving or get a nosebleed it doesn't hurt yet it can look pretty brutal. If I get a nasty cut it can really hurt but not cause much blood. Is it

would be a real issue at relativistic speeds. However, it's an issue that would have to be solved regardless of ship geometry -- you can't plan for some chunk of your ship to be constantly bombarded by hard gamma rays. As such, once you've solved the problem, it's likely a solution that can be

Actually you start to get chemical reactions between impacting particles and the hull when the energy is a few tens of eV per particle. For hydrogen, that occurs at ~50 km / s, i.e. 0.01% of the speed of light. Beyond that it is basically impossible to design a hull that wouldn't be eroded by

is probably not round, but that may be due to its fast rotation. For the smaller objects the shape can not be determined with acceptable accuracy at present. That puts the upper limit on the required mass at the order-of-magnitude of (1-3)*10 kg; but it may be lower than that. Hope this helps.

The problem tends to be that time is a continuous function in the real world - but inside a computer it pretty much has to be quantised at a fairly gross level (like maybe 1/100th second increments). Also, in the computer, we don't have infinite precision and precision errors can "leak"
