Other Sciences

I saw a really stange exhibition in Belgium and am writing a play about it. But I need some help with the science. This exhibition was all about 'life from death', and had dead animals linked up to volt meters to read their voltage as they decomposed in order to prove that electricity was still generated even in the death of the body. Another part of the exhibition was this... A severred human finger linked to some kind of machine that was measuring the frequency it was producing as it decayed and this was being amplified and played in the chapel - which create a really weird whirring and humming whistley sound. If anyone can explain two things: 1) Could dead anim…

I added a luke-warm supersaturated solution of gelatine to our slightly under inflated water bed mattress? If we then cranked the heat up on the water bed and made waves to mix the bladder, would we get a slightly viscous water bed?? Say the bladder is 2.7m long and 2.2 m wide and 40 cm deep, how much gelatine would I need to make the bladder a nice comfy jelly? Thats 2.376 m^3, which is 2376 litres of water. Would anyone recommend I try it?

Imagine if you placed some liquid nitrogen in a rocket or plane of some sort, flew above the clouds and released the liquid nitrogen back down to Earth. In the process of the liquid nitrogen falling it'd pass through the clouds and because it is soo cold immediately solidfy them. Meaning that rather than having a little bit of rain you'd have massive chunks of ice, which'd be kinda dangerous, but hey, at least it'd be sunny afterwards! It was just an interesting thought.

Hey this is just a general question to all of you Do you guys think " Aliens" exist? Please give reasons for ur answers (in detail)

Hey everbody i have a sociology paper due in two weeks, and the topic is school shooting and violence. i came acroos some very cool statistics but i can't seem to get a hold of any theories that i can cite if anybody has info on such theories such as causes of school shooting or its consequences on society, please let me know the author or if possible the website/book i can find the info also any original ides about causes are appreciated. thanks

Hello, I am new and couldn't figure out where to post so I decided to post here. Sorry if it was the wrong one. Question: Due to the Earth spinning, the ocean currents of the Norther Hemisphere of the Earth are supposed to circle in a clock-wise direction, for example, The Gulf Stream. But what I do not understand is that why do some currents go in the opposite direction. For example, the Greenland Current. Please explain this to me. Thank You

I'm trying to figure out how efficient/inefficient a certain light bulb is. I'm not sure where to post this, but I'm not sure which area this applies to. I don't know where to start on this and was hoping someone could point me out in the right direction. Thanks.

Hi, I'm an Englishman in Amsterdam, 'like my toast done on one side' etc etc. Here it’s legal to smoke marijuana at your 'home or certain designated places'. When I make a joint (tobacco combined with marijuana) I produce off cuts of tobacco combined with small bits of marijuana. Over the years these off cuts are enough to fill a largre bag. From crude calculations I understand there to be over 200 euros worth of marijuana mixed in with the tobacco. To sift and manually remove the marijuana is very time consuming and tedious, therefore I would like advice on possible methods for extracting these two materials from each other. As the materials are similar (both plants)…

How exactly does this work? I've think that nitrogen is pumped into a sample and the amount that is pumped in can be used to measure it's surface area. Am I right?

well what is the chemical composition of oil?

Sometimes, when I bake a piece of *apparently* fresh (i.e. unfrozen) meat (e.g. a roast) or chicken, I find quite a bit of water collected in the roasting pan. Sometimes, there's very little. Anyone have any guesses as to what the presence or absence of water means? I suspect it might be related to whether the meat I'm cooking has previously been frozen. If it was frozen at some point, I imagine the cell walls would probably burst and would release lots of water. If so, then I would expect to find very little "leaked out" water when I cooked the meat, since the water would have already leaked out when the meat defrosted.

If you tunneled to the center of the earth and hollowed out an area in the very middle (ignoring the heat, magma, etc.). Would you, in the center, feel weightless because your body was being pulled in every direction (more or less) equally. Or would you simply be ripped apart for some reason that I don't know about? Thanks

So, in all of my spare time (which is like, nothing... ), I'm undertaking a rather ambitious project, and I'd like some help as to where I should start. The long and short of the project is to create a grid, similar to an LCD display, that: Controls the "status" (on or off) of infrared light Is backlit by an infrared laser Can control areas smaller than the size of the laser beam (in other words, multiple cells in the grid per laser beam - with preferrably only ONE laser beam - just like the many pixels in an LCD screen to the one backlight) Is controlled, whether directly or indirectly, through electric current, preferrably distributed in some type of grid Conta…

Can someone please help me on Carbon Dating &Thermal Luminescence Dating I Desperately need help on the subject!!

Hi. How many millions of years has our sun been burning ?... All that mass reduction being consumed to radiate energy for that lenght of time, has reduced its gravitational force attraction, and keeps happening, is it? Then, its pull is not a constant ! For the earth to maintain orbit on a decreasing solar gravity pull, the orbit diameter has to continuosly diminish accordingly, does it ? Or the orbiting speed slowing, does it? Miguel

I'm sure this isn't the right forum but Ill ask here and see if anybody can help me. I just bought and received an iPod mini. The iPod did not come with an ac charger. You charge the battery with the USB cord. Thats all fine and dandy but the problems comes in when I travel to Europe. This summer I will be going to the UK and France. I will not be bringing a laptop so I have no way to charge the battery. I can buy the travel kit sold by iPod but I would also have to buy the charger which would total $90. So heres the question: The travel kit looks like its just physical adapters that fit into the charger for the outlets in the different countries and it *l…

Hey... Well tonight I distilled some water by boiling it for a few minutes. I had 4 D sized batteries hooked together to form a battery pack. I then had 2 stainless steel screws, hooked to wires, which were hooked to the battery terminals. I was trying to separate the water into hydrogen and oxygen, not sure why though. Well, I read online somewhere that salt makes water conduct electricity better, some I threw in about 5 tablespoons of salt. (yes that is A LOT) Then, I plopped the screws in the water. The positive side bubbled fast (oxygen) and the negative slow (hydrogen). I had a glue stick cap at the top of the hydrogen screw because that is what I wanted to collect.…

I'm in the planning stage of building a wind tunnel, and I think I have it about down - except for one "minor" detail. How do I make the air that is passing through my wind tunnel visible, so that I can see how aerodynamic the things that I'm testing are? Does smoke work for this?

do you know of the value of the volume expansion coefficient of lead? or what site could i visit in order to get an exhaustive list of expansion coefficient values... thanks...

OK, lets say you have two high voltage systems (like neon sign transformers) that are isolated from each other. If you set it up so the outputs were arranged like this: ...- -.....+ ...+ So two arcs are forming one between each pair of outputs. Would the arcs avoid each other or merge? (Lets assume that the outputs are identical in every way)

i remembered a question that goes somthing like this: electrons have speed as much as 10 ^6 m/s. Why won't these electrons fly out of the conductor?

Greetings all..I am new here. I did not know where to post this,So I just posted it here. Ok..Basically I am searching on any and all scientific studies done on hand to hand combat. I am not talking about any martial arts or anything like that which claim whatever they do is "scientific" I am looking for legit studies done following the scientific method on brainwave patterns during combat,muscle reactions/muscles used during combat,Physics behind hand to hand combat I.E. Kinetic energy ect,Chemicals releashed during combat or other situations of the such,Advanced critique or studies of numerous particular forms/styles of combat varying from country to count…

As a homebrewer there is always the danger of Methanol being produced instead of ethanol. How do i test for this? Drinking my homebrew, certain batches make me feel really tired, is this a symptom of methanol poisoning?

Why does salt water conduct electricity best at higher temperatures?
