Assume you have something that generates heat at N degrees. If this heat source were stuck inside an oven and there was little to no way the heat could escape, would the temperature inside the oven eventually go above N degrees?
The second law of thermodynamics says that heat flows from hot to cold. If the system someh... |
Why do images flip in a magnifying glass at a certain point?
So I was looking through a magnifying glass and I noticed that when I looked at an object that was about three feet from the magnifying glass (how close it was to my eye was irrelevant... I think), the image in it completely flipped.
This picture is helpful.... |
What do moles do during floods?
Though I cannot find what I'd consider to be highly scientific sources (lots of gardeners answering), moles dig their tunnels deep enough and at specific angles to avoid water getting into their nests. The soil saturated with water only goes so deep, and established mole tunnels are deep... |
Cell Respiration
Alright maybe this should be in biology but it’s a question so I put it here. In school I have to make my own lab for cell respiration. We had done a lab that if you activated yeast and put it with molasses in a test tube with a stopper and "U-tube"? it would release CO2 (I think) and you would see bub... |
What stops water from continually sinking through the ground? (Primary school science question)
My year 4 class started looking at soil composition today and one of the students asked why water doesn't keep sinking through the ground. I promised them I'd have an answer by tomorrow (Sydney time), so I'm hoping the kind ... |
Wavefunction collapse is faster than the speed of light. Doesn't this just mean that they used math to answer the question?
I keep reading about how researchers are measuring the speed of the collapse of the wavefunction by sending entangled particles to two different locations, measuring one, and then checking the oth... |
How do bugs actually stick themselves and walk on walls and ceilings, y'know, like Spider-Man?
They’ve usually got little claws on the ends of their legs and they grab onto the texture of the surface. They’re also extremely light, so it doesn’t take much friction to hold them to a surface. You’ll note that the larger... |
What is it about a digital camera's sensor that results in noise artifacts in low light settings?
I understand that stronger lighting means more information to outdo the noise, but why does the noise appear in the first place?
Part of it is thermal noise. The electrons in your sensor have some thermal energy associate... |
How is a mosquito proboscis physically capable of puncturing human skin?
Human skin should be way too dense and strong for something so small and fragile like a mosquito. How is this possible?
It uses two maxillas to cut its way into the skin so the fascicle can enter while the labium remains on the surface of the skin... |
What happens if a gun is fired inside a pressurized cabin? (Like in an airplane)
Today my military friend was trying to tell me that if a gun was shot at a high altitude in a pressurized airplane, that passengers would die from the force of the blast from the muzzle. (Not the bullet, unless of course it hits someone). ... |
How do photons interact with eachother?
Generally photons don't interact with each other, but in a non-linear medium it is possible. For example, two photons can combine to excite a molecule to an excited state with an energy difference equal to the sum of both photons (two-photon absorption TPA, a third-order process... |
If the gas in a solar nebula is blown away as soon as the star becomes hot enough for hydrogen fusion, why are there different-sized stars?
It's my understanding that all stars, at least ones that weren't formed in the early universe, were born in solar nebulae. The gas cloud spins around, and at the very center a sta... |
Is there a correlation between 1 cal = 4.184 J and water’s heat capacity of 4.184 J/g°C?

What exactly does a scintillation counter measure?
I've done a bit of gamma ray spectroscopy, and I'm trying to interpret my results, but I don't know enough about scintillation counters. So lets say a gamma ray comes in, generates and electron-positron pair, and then undergoes a few compton scattering events. The posi... |
How do we keep track of human genetic change? How much change would need to occur before scientists could say a new species of humans has evolved?
I recently saw an exhibit about the brief period when neanderthals and homo sapiens co-existed, both of which could be classified as humans. I've been fascinated with the pr... |
What is the physical significance of a commutator in Quantum Mechanics?
It is my understanding that you can use commutators to determine the uncertainty relationships between some observables but I am still having a hard time understanding what the physical meaning of the expression [A,B] is. Also, in addition to the o... |
Why is human beard hair so much coarser than either body hair or head hair?
Is it simply a matter of evolution? As beard hair shields a hunter's face against the elements while hunting, it would obviously be an advantage to have facial hair that is stiff and loose to mitigate wind chill or precipitation. What proteins ... |
How were heavy vehicles steered before the popularization of power steering?
Manual steering requires a lot of force even with a moderately heavy vehicle such as a mini-van, but power steering wasn't really around commercially until the 1950s. How did heavy vehicles such as cargo trucks get around this problem?
Many ol... |
Can black holes be used as giant space mirrors?
Black holes have strong enough gravity to prevent light from escaping. Could they also have light orbit them, such as how planets orbit stars? If so, would it be possible for black holes to have a slingshot effect on light, essentially sending it back in the direction it ... |
Do babies need to breathe after birth if the umbilical cord is not cut?
Babies clearly breathe after birth since they cry, but if the umbilical chord were left alone, would they to? Does the mother stop supplying the baby with nutrients/oxygen after birth?
There is so much to this, so I’ll try to be brief, but also cov... |
Why did Nordic people evolve to have thin bodyhair and blonde hair while people in hotter regions have thick bodyhair which would be better suited to colder climates?
In terms of heat insulation, why didn't people in colder climates evolve to have thick and dark bodyhair which would help you keep warmer. And on the con... |
Does it take the same amount of energy to slow down a space craft as it did to get to that speed?
That depends. It can take less, more or the equal amount of energy due to gravity assists. But let's imagine there is no matter around you. To move forward you need propulsion, and to stop you need the exact same amount of... |
What is in between galaxies?
after seeing this picture ( ) I became curious about what is in between galaxies. I know it's a bit of a silly question but is it just empty space or is there more to it? Any info is greatly appreciated.
The 'intergalactic medium' (IGM) is mostly a rarified plasma. The heating mechanism dep... |
Why aren’t waterfalls just eroded to slopes?
I can understand that water needs some place to go and sometimes the easiest path is over a ledge. However, I would think that the power of erosion would convert these waterfalls into smoother inclines. Are waterfalls usually just the result of recently redirected water wher... |
If electric cars become the norm, is it likely it would be economically feasible to own a gas powered car?
Let's say would it be feasible for a middle class guy?

If our skin cells die and regenerate so much, as well as most of the other cells in our body, why are tattoos still visible after so many decades?
Our skin has several layers, the top being composed of the epidermis (keratinized dead layers of cells) and the dermis (where your nerves, blood vessels, and epithelial prog... |
When touching something without looking at it, why is it difficult to distinguish cold from wet?
I first noticed this the other night while in bed, I reached my hands across my sheets and thought I felt something wet. It turned out to just really cold. It got me thinking and I tried out a few objects blindfolded, such ... |
Is it possible that the end of the sunspot cycle could significantly slow down global warming?
Sunspots, the enormous magnetic storms that erupt on the sun's surface as the cycle builds, might disappear entirely for the first time in approximately 400 years. If the reported trends continue—a big if, other researchers n... |
Are comets constantly shrinking? That is to say, are they losing mass through their dust trail?
That is to say, are comets like Halley's comet going to disappear one day?
Comets are constantly losing mass. There is a finite number of passes a comet can do before it "turns off". However, common belief is that the comet ... |
If Thorium is so abundant and cheap, why is it so hard to get a sample of?
video from "Periodic Table of Videos" stresses how hard to get Thorium is, but every proponent of Thorium ever has noted that a major benefit of thorium is that it is so abundant and cheap to mine... So which is it, and if it's both, then how is... |
A question about redshift
Okay, redshift. The distance between me and a galaxy far, far away increases because the universe is expanding, and this shows up as a redshift. In analogy: if I have a magic box from which an ant shows up every second, i get one ant per second if I put it on my desk. If I glue the box to a ba... |
Is it possible that there are stable super-heavy elements (beyond atomic number 100)?
Is there a law against it or is possible just taking a large amount of energy?
Probably not. There is a proposed island of stability . However, this is a relative descriptor, as being able to work with something that might last for ... |
Why aren't airplane fuselage and/or wing surfaces dimpled?
If dimpling significantly reduces drag on a golf ball, why can't a similar principle be applied to airplanes? If I remember correctly, Mythbusters tested dimpling on cars and concluded that it did improve fuel efficiency.
Before adding some other factors I'd li... |
How is our body able to create the material our nails are made from?

A question on nuclear decay and the number of nuclei.
The number of nuclei of a number of atoms after a time t can be defined with the equation: N = N(0) e The half-life (T) is therefore when N = N(0)/2, and so: N(0)/2 = N(0) e ; ... ; T = ln/λ If we were to represent N(0)/2 vs time on a graph, we would get this graph:... |
What is the psychological mechanism that causes things like songs or food to "get old"?
If I listen to a song I like a lot, after a while I get bored of it, and eventually I'll start to downright dislike it. The same thing happens to everyone with certain foods, movies, even places and people. I just wonder why somethi... |
Why is there only one species of human?
There are a variety of reasons, but here are two: 1: Due to our technology and general intellect, humans around the world have been able to live in far more similar conditions than another, equally distributed species. 2: We are a relatively young species . Since the migration f... |
What caused the super-continent Pangea to split up in the first place? Is that same force still driving the plates in their movement?

Curvature of Earth and its effect on travel.
On a trip from India to US recently, I saw the path that my flight took, because they display it on your monitors. In image, the yellow line is the path that it actually took, but from what I understand, red should be the shortest path. So, I told this to a friend and he was... |
Do humans (or other animal species) give off ultra-violet colors similar to flowers that we can't see?
Is that why bees circle us? Or is it merely our scent? Or is it just a warning for us to get the fuck out?
Apparently, they look like they've been smeared with pitch. Here's a link to two pictures one is taken using a... |
How does radiation cause mutations?
Simply put, radiation breaks the strands in your DNA. The DNA can repair itself, and it usually does this quite well. A fraction of the time though, the repair process isn't done properly. This means the DNA is now slightly modified, which can affect the next generation of cells. |
Does Hydrogen Peroxide kill bacteria?
Hi, So I got into a debate elsewhere about whether H2O2 can actually kill Bacteria. There was also suggestion of it "promoting healing" etc. of which I am more dubious. Peroxide breaks down into Water and Oxygen free radicals, and my understanding is that this breakdown is catalyse... |
Are there any methods of recording uncertainties without observing them?
Quantum Mechanics has many particles and functions which are in a state of uncertainty until they are observed, where they collapse into a single state. My question is, are there any methods, theoretical or real, to record such things for future o... |
How can gene modification work in a fully mature adult?
I understand how we can change the DNA info in a single cell and all but how does this spread to the rest of the body? It makes sense with a zygote because the single cell will split and become all the cells in the body but how does this work with a living breathi... |
Is it possible for an anion to exist in solution without a cation and vice versa ?
Yes, this is actually the basis for bioelectricity used in our nervous systemand muscles. Our cells actively seperate ions to create electric and chemical gradients that can be used to power other reactions (typically transport accros th... |
Do ants (and other small bugs) take fall damage?
Technically yes, since they are falling downwards, but their terminal velocity is not nearly high enough for any real damage to occur. Plus, most bugs have strong exoskeletons or squishy bodies that can absorb impacts very well relative to their size. |
Do we have a man-made satellite with a big elliptical orbit around the earth?
And if we do what would be the purpose of this orbit?
Yes! A good example of a very useful large elliptical orbit is a Molniya orbit . It serves the same kind of purpose that a geostationary orbit does, however it's designed so that most of ... |
What do you catabolize first during starvation: muscle, fat, or both in equal measure?

Why are the physical electromagnetic fields only the real part of E and B?
says that the physical fields are only the real part of E and B, but this is not obvious to me. Since e = cos(x) + i sin(x) We get an imaginary part of the fields in the picture, but somehow these aren't actually a part of the fields, or how sho... |
Is hydraulic fracturing and shale gas really harmful to the environment? How would it compare to other energy sources including all steps from extraction to consumption?
