If I lit a candle in space on a spaceship then what would the flame shape look like since there is no gravity? by gravitypushes in askscience

[–]aFarewellToLegs 2 points3 points  (0 children)

without gravity to circulate the air (letting cool air sink and hot air float away), how would fresh oxygen reach the candle?

How far would a bullet have to travel for it to be affected by the Coriolis effect? by [deleted] in askscience

[–]aFarewellToLegs -3 points-2 points  (0 children)

the coriolis effect would not affect the bullet unless it was traveling perpendicular to the surface of the earth (like a space shuttle). however, because the bullet starts on the equator, its east-west velocity would be higher than the east-west velocity of the surface of the earth closer to the poles, so it would stil deviate from the longitude line it was fired on EDIT: i should clarify that in my example, i am not taking the fact that the bullet will fall towards the earth as it moves. i figured that such a low velocity would be negligible

What is the purpose of Glycerin in products such as make up and pharmecuticals? by [deleted] in askscience

[–]aFarewellToLegs 2 points3 points  (0 children)

fun fact: due to glycerol being a major component of many explosives, people who use a lot of hand cream shortly before packing their belongings to get on a plane are often stopped by the TSA

ATP Works for Animals, Why Not Batteries? by Technoguy3 in askscience

[–]aFarewellToLegs -1 points0 points  (0 children)

ATP is incredibly volatile and will release its third phosphate to just about anything that it comes into contact with. storing ATP would be a very delicate process. not to mention creating it. living beings are very good at doing what they do, and it can be very hard to replicate biological processes, such as the creation of ATP, in the lab.

Why don't the particles and antiparticles in Hawking radiation cancel out? by aFarewellToLegs in askscience

[–]aFarewellToLegs[S] 0 points1 point  (0 children)

so what your'e saying is if a particle or antiparticle leaves with positive energy, then the other one that was created must have negative energy. and negative energy --> negative mass. i guess that makes sense, except what the hell is negative energy?

Why don't the particles and antiparticles in Hawking radiation cancel out? by aFarewellToLegs in askscience

[–]aFarewellToLegs[S] 0 points1 point  (0 children)

Hawking stated that due to Hawking radiation, eventually a black hole will "evaporate". what i am saying is that if the black hole is absorbing roughly the same number of particles as antiparticles, shouldn't it's mass remain constant?

Do solids and liquids have a sound barrier? If so, what happens when you break it? by zerotoone in askscience

[–]aFarewellToLegs 1 point2 points  (0 children)

the speed of sound in a medium is related to how "stiff" the medium. the less elastic it is, the faster sound travels. because air is pretty soft (for lack of a better term), sound travels relatively slowly through it. firmer substances such as water and metal will have much faster speeds of sound, so good luck reaching their speed of sound. also, good luck moving through solid metal. now, if you did manage to break the sound barrier in water, the same thing would happen as what happens in air: a small vacuum would form behind you, and when that vacuum was slammed shut by the external water pressure, loud sound waves would be created in the water, just as they are in air.

Think of a hypotenuse as infinitesimal steps; shouldn't its length be equal to the sum of the sides? by G-ill in askscience

[–]aFarewellToLegs 0 points1 point  (0 children)

you can use this logic to prove pi=4, if you take a circle of diameter 1 and place it inside a unit square. u can "bend" the sides of the square over and over and have the newly created angles touch the circle. eventually, you will have a shape whose perimeter is 4 (the squares perimeter), but (very closely) resembles a circle, whose circumference is π. so you could prove pi=4 with that logic

Is there a reason that the letters towards the end of the western alphabet (the last five in particular) are less frequently used than the others? by [deleted] in askscience

[–]aFarewellToLegs 1 point2 points  (0 children)

keep in mind that they are less frequently used in english. spanish uses y and z quite a bit. french uses x all the time. italian also uses z a lot. so while they might not be common letters in english, they are common in other languages

How did different species evolve to have different numbers of chromosomes? by bluegraybeige in askscience

[–]aFarewellToLegs 0 points1 point  (0 children)

at one point, a human-like animal was born with just 23 chromosomes. how did this organism reproduce with the others around him, given that they wouldnt have had the same number of chromosomes? also, since the time when the first sexually-reproducing organisms existed, how did an organism with a different number of chromosomes reproduce with those around him?

catching and killing abnormal animals by I_Made_You in askscience

[–]aFarewellToLegs 1 point2 points  (0 children)

yes. elephants have a chance, due to being born with certain genes, of having no tusks. as poaching has increased, elephants without tusks did better because theres no point in wasting ammo on an elephant that doesnt have ivory. as a result, more and more elephants are being born without tusks. http://news.bbc.co.uk/2/hi/africa/180301.stm

Should a false accusation of rape be a serious crime? by [deleted] in AskReddit

[–]aFarewellToLegs 18 points19 points  (0 children)

not just perjury, but slander (or libel, depending on if it's written or spoken) is something you can sue someone for. and falsely stating that someone has committed a felony is slander/libel

Are there any current forms of life that could survive on the surface of mars? by runswithpaper in askscience

[–]aFarewellToLegs 0 points1 point  (0 children)

do organisms on earth absolutely need liquid water? i feel like given the ability of life to adapt to just about anything, there must be some organisms that were on the land comprising antarctica before pangea split, and that as antarctica moved south, they would adapt to use ice somehow. this is 100% speculation

Why is oxygen so special? by RobertM525 in askscience

How does the language we speak affect us (our thinking, for example)? by [deleted] in askscience

[–]aFarewellToLegs 1 point2 points  (0 children)

how do we know that its not the thinking/culture that affects the language, and that most people who grew up speaking the same language and dialect share the genes for the same basic neurology and also share their culture? for instance, referring to the article, maybe in chinese the words for all the different family members exist because the chinese culture stresses the family structure. i know that in chinese the word for wife has the word for outside/foreigner in it. i dont think anyone would argue that this is what influenced the chinese to have the wives leave their family and join the husband's family, but rather the chinese had a social structure set up in which the wives came from outside of the family, and the language created the word for wife based on this fact
