Speaking in terms of cultures / civilizations, how far along does one have to be to understand prime numbers? What are the prerequisites? Verbal language? Written language?

Speaking in terms of cultures / civilizations, how far along does one have to be to understand prime numbers? What are the prerequisites? Verbal language? Written language? I ask because I'm working on a novel (sci-fi) in which a planet has been set aside to preserve a potentially sentient species. On this planet, there are observation stations. The doors to these stations need to be protected by something hard enough that it requires cognitive reasoning to overcome, but still be designed to be accessible once the species is able to understand the information contained inside. I'm thinking of a combination lock where to decipher the combination, you have to be able to factor a number into primes. For example, the lock may be lock #21, and the combination would be 3-7.

• ### What song has this refrain?

Looking for a song I heard on the internet. The refrain includes "you are the soul of my morning, the angel of my night" and "keep our love alive." It was a contemporary blues sounding song. Mahalo!

• ### I need something translated into florid Spanish?

I'm writing a sci-fi book. In it, as a historical footnote, is a quote from the next person to set foot on the moon. This will occur (in the book) on the 200th anniversary of the first moon landing, and the fellow who makes that next historic footprint will be a native Spanish speaker.

This will occur (in the book) on the 200th anniversary of the first moon landing, and the fellow who makes that next historic footprint will be a native Spanish speaker. His words for the occasion will translate as: "At last our footprints again leave our mother Earth" I don't particularly care what flavor of Spanish is used, but I do want to be sure the translation holds water. I don't particularly trust Babelfish for this! Oh, his name, at least tentatively, is Gaspar Eutimio De La Vega. Chosen with guided randomness from internet resources. Is that a believable name to someone with fluency in the tongue? Thanks!

• ### Why are my potted herbs dying?

Early in the summer, we bought a selection of potted herbs. We moved them to bigger pots with fresh soil. I waster them daily and feed them weekly. Now, though, half of them are dying. I thought it was a lack of sunlight caused by moving shade as the season shifted, but moving them into more direct sun didn't help. Weird thing, the pots... show more

They have a couple of gallons of soil in them, but feel like Styrofoam.

• ### Injuries from carrying another person?

In a book I'm writing, there's a segment where one character (female) has to carry another unconscious character (male) to safety. He outweighs her by about 20 pounds.

In a book I'm writing, there's a segment where one character (female) has to carry another unconscious character (male) to safety. He outweighs her by about 20 pounds. The terrain is a relatively level forest, transitioning into a marsh. She is using the fireman's carry, and carries him until she is at the point of collapse herself. What I'm interested in is how this will impact the female character in days/weeks/months to come. Will it be something as minor as muscle soreness? Or would it be something more severe, like stress fractures, torn ligaments, other? What would be a best case scenario? And average case? Worst case? Mahalo!

• ### Theoretical maximum velocity for a bullet?

I've come across various casual references over the years to the fastest velocity a bullet, propelled by gunpowder, could reach. (To be clear, I'm talking about a typical cartridge, primer, powder, and bullet type of ammunition, not something exotic like a rail gun or a rocket-assisted round.) I've seen 6,000 fps and 7,000 fps cited. ... show more

I've seen 6,000 fps and 7,000 fps cited. I assume this figure would be based on the expansion of gasses from burning gunpowder in a non-confined area. However, I've never been able to track down a source. People will say things like "oh, it was in an article in Shooting Times a few years back." Can anyone point me to a source for this? Not a forum where someone is claiming to know, but an actual published study. Mahalo!

I bought this gun used. It is a fantastically accurate gun, complete with the adjustable aperture and front globe sights. With CCI SV ammo, I can hold sub-MOA at 100 yards off a bench. But, there's some damage to the chamber. I don't know if it was "shot out" or otherwise damaged by the previous owner, but there are visible grooves where there should be none, and I get backblast of powder. When I shoot standing, I can feel little bite on my left wrist each time I pull the trigger. I don't really want to replace or reline the barrel, given what a great shooting gun it is. Is there anything I can do to mend the chamber without impacting its otherwise excellent performance? Pictures here: http://www.flickr.com/photos/30450170@N0...

• ### Precision load for m1903a4 Remington?

Aloha! I've got an a4, it's a family heirloom. Unfortunately, it has been sporterized, and the receiver has been drilled for a modern scope.

I've decided to take it farther in that direction, and have bedded the action in a Boyds benchrest stock and mounted a decent Bushnell Elite scope. Now, I'm searching for a good load for precision shooting at up to 600 yards. My research indicates that the 1903 series preferred heavier bullets than M2 ball, and that snipers used 185 gr match ammo whenever possible. Has anyone out there worked up a load that will hold MOA out of a 1903 at up to 600 yards? Thanks!

• ### What would a buried radio transmitter sound like?

However, it's intact, everything is in working order, and it has some power, enough that its emergency radio beacon is operating. What would that sound like to a searching craft with a radio receiver? Would the content of the message be intact, somewhat garbled, or just static? How about directionality... would searchers have a harder time triangulating the location? How much would the power of the transmission be diminished? Thanks in advance!

• ### How long would it take a spaceship capable of 3-g acceleration to travel 1 light-month?

I'm writing a sci-fi story, and need a ballpark answer. The ship needs to accelerate to the midpoint, then decelerate to a stop, covering a distance of 1 light-month (roughly 32.4 billion km). It can maintain a continuous acceleration / deceleration of roughly 3-g (roughly 30 km/sec/sec). How long does this trip take? Thanks!

• ### Name of a desolate place in Greek mythology or legend?

My boss uses this term a lot. Contextually, he obviously means it as an insult, but I can't get a grasp on it. It seems to me that if a person were a "tool," they'd be a person used by someone of higher power or authority. The "tool" would be there to implement his (or her) master's will, and not be capable of pursuing an independent agenda. "Puppet" would be a good synonym. However, that just does not fit any of the situations where I hear one person call another "tool." I hear it most often from my boss, but also from other places, and it consistently seems to be purely pejorative with no specific meaning. Can someone clarify? Mahalo!

She just keeps licking and licking at her tummy and bacl thighs. Pulls all the fur out. The skin underneath doesn't seem irritated or anything. She's around 7-8 years old, fixed, and is about a year overdue for her maintenance shots.

I showed a lot of improvement, so he said I can go back to a mild natural toothpaste. The thing is, I kinda LIKE the baking soda and peroxide. No obnoxious flavors, easy to rinse, doesn't make me gag. I looked about on the web, and while numerous sites espouse the tooth-whitening values of this combination, I can't find any that say if it is a good (or bad) idea to make it my regular oral hygiene regime.
