Yes. But that would be a long enough time after the end of everything interesting, that the concept of time will have little meaning.

What's the name of the property of a coin for whether its faces are right side up when flipped on horizontal or vertical axes? So in Canada our coins follow Coin B and all the US coins I've seen follow Coin A. Basically: Why is it okay for presidents to do headstands but not the Queen?

TVsVeryOwn posted:What's the name of the property of a coin for whether its faces are right side up when flipped on horizontal or vertical axes? It's called the orientation or alignment, or more specifically the die axis. There are two general types: medal alignment, which is what you have in Canada, and coin(age) alignment like what you see on US coins. As to the why, I'm not sure. Coin alignment is the older one, medal alignment is a later standard. Presumably because it's faster with a hammer to just flip the coin and hammer rather than flip and turn, then hammer. Not sure there's a great deal of rhyme of reason other than it's a set standard. Medal alignment is the more common sense variety I guess.

Is there a way to objectively and accurately determine the time without referring to another clock? All the SI units can be derived from physical phenomena, but is there actually a definition for the time in the same way, or are we just setting clocks based on a consensus of the most accurate and accepted clock?

Nope. GMT is roughly pegged to solar noon at the Greenwich Observatory, but there's drift between it, Universal Coordinated Time, International Atomic Time, etc. For fundamental physical phenomena, duration matters, but absolute time since the big bang is completely irrelevant.

Interesting podcast about this exact question. quote:Dr. Pamela Gay: And the convenient thing is that time, seconds, is also defined somewhat naturally. In this case it’s a bit more complex. It’s defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyper fine levels of the ground state of the cesium 133 atom.

So it's incredibly unlikely but (almost) guaranteed for something like that to happen in our universe as opposed to some theoretical, untouchable alternate universe operating alongside our own? Well, if you're going to go with quantum probability, you have to also ask if the chance of quantum fluctuation producing, say, a perfectly uniform universe of a very specific size with a very specific configuration or whatever is more likely than a universal collapse (rendering time finite). So, there's a nonzero chance the universe collapses on itself and time "ends" prematurely, which renders all states finite, and you need to consider the probabilities of a given event versus universal collapse. The better question is, how do you want to define infinity?

While it is incredibly, astronomically unlikely that random quantum fluctuations will ever poof the complete eiffel tower into existence, if the heat death timeline truly stretches to infinity it is not only, likely, but (almost) guaranteed to happen not once, but an infinite times. Any possible-but-improbable event has a probability of happening that increases with time, forming a never-ending sequence 0.9999999..... The question is, does 0.999999.... = 1?

Phyzzle posted:Any possible-but-improbable event has a probability of happening that increases with time, forming a never-ending sequence 0.9999999..... As t approaches infinity, yes. Trouble is, t only exists while spacetime does. If the universe collapses at a non-infinite time, there's a finite non-zero chance that it collapses before t gets close enough to infinity for your improbable event to happen. If it were absolutely impossible for spacetime to end, then eventually all possible quantum states would come to pass. Infinity is a really loving long time.

Baron Porkface posted:Is sound a form of radiation? Yes, and no. "Radiation" is as far as I know, in daily speech, only used to refer to electromagnetic radiation, such as light, radio and microwaves or ionizing radiation. Sound is, of course, something else. However it would not be wrong to call sound a form of radiation as it does indeed radiate, but as waves through a medium rather than as photon wave-particles. Sound certainly is a way for energy to be transferred to one place to another, which is one reasonable criteria for calling something radiation.

There is acoustic radiation, which encompasses seismic waves (waves through a medium, like air), but it's not common to call sound waves "radiation", since it's almost exclusively used for electromagnetic waves. Broadly, radiation is a way of transferring energy in the form of waves. More specifically this refers to electromagnetic waves, but you could refer to seismic waves as "radiation" in a specific context, like at a environmental engineer gathering talking about harnessing earthquakes for power.

I'm on the tail end of a cold, and as usual, have a lingering dry cough. Dextromethorphan doesn't touch it. Halls drops work decently while they're in my mouth, but that's not an option at night, and it'd be nice not to have that taste in my mouth all day. What other options are there?

If a cough isn't healing itself, prescription is really the only way to go. Like you note, cough drops don't last long enough to do any good, and dextromethorphan is of questionable usefulness. Codeine's is probably what'd you get, although you might also get something like prednisone depending on where exactly the cough is coming from. source: long history of getting bad coughs after colds

Actually DXM does help if you take like 60 to 80 mg instead of the directed 20. That amount will buzz you a little bit, but it's nowhere near enough to get you robo-tripping. Not sure why the prescribed amount is so ineffectively low, but I've always assumed it was a CYA thing on the part of pharma companies.

If so, they might sell DXM in pill form near you. I recommend you take the entire bottle at once and drink some orange/grapefruit juice to wash it down. You’ll forget about your cough while you trip balls to psychedelic music of your choice for 4-6 hours in the dark. Edit: since this is a place for real questions and real advice: do not take the entire bottle. It is bad for your brain, probably.

Allergic to Oranges (and pineapple) so your recommendation is extra bad for me  I'm not the original question-asker, though, I get sick rarely enough that I can tolerate the occasional death cough once every couple of years I think DXM is a precursor to an SSRI? Maybe Paxil? Wikipedia says it has some Seritonin functions so they probably made something out of it that would be bad for your brain AND your liver

The barfing could be the guaifenesin (an expectorant) which is added to most cough formulas. That poo poo is the best reason not to drink a whole bottle. Some products contain DXM only, which is what robo-trippers mostly go for. I don't know too many brands offhand, there's Delsym (which is also time-release, which may be ideal), a CVS store brand, and Robitussin makes a few DXM-only but not every store carries those varieties. The best one though is the Dollar Tree store brand if you have those where you are. 15mg softgels x 15; a great value for only a dollar.

Tea with lots of honey and a little lemon juice. Or, hot water, rum, honey, cinnamon, and lemon juice. Or, just straight honey. Tessalon Perles are effective but require a prescription. Codeine cough syrup (by prescription) was really helpful when I had bronchitis.

That’s weird! I have T3s for when my back gets really bad and if I have a cold and cut one in half it takes care of my cough better than anything else I’ve tried. I always assumed that opiates = respiratory depressants = cough reduction.
