Hey all! I am writing a 10 page research paper on technological singularity and presenting the topic with a 12 minute presentation. I was hoping to get some of your ideas on technological singularity so I can expand on my own ideas already (one of the areas I am covering is ethical questions involved with artificial/above human intelligence) So please comment your view point!

So technology seems to stabilize after awhile where it won't advance much further and there are examples of that. First I will start out with an example of a technology that has more or less stabilized, the gun. The first guns were these big cannons from the 12th century. Then as they got more advanced they were able to shrink guns down to the size where they could be used and carried by a single person and we had matchlocks which were long guns that were fired by a burning wick that was lowered into the flash pan with a lever, setting the powder off. Then we had wheel locks which used friction wheels instead of matches that produced sparks which set off the powder.…

I'm not a big fan of geology, but I'm looking at a map that shows tectonic plates and which direction they move. I was wondering whether or not the direction of the plates will change or has changed in the past. Secondly, I was wondering if a plate could be swallowed. I think I'm referring to an ocean trench. How does that work? Does one plate go over another plate? What if that plate is entirely engulfed?

has anyone ever that expression before or "Stop making that sound, it`s putting my teeth on edge". things like the Skrrreeeeeeeeeeeeeeeech when finger nails go down a blackboard, or rubbing polystyrene together. it seems to make some people go crazy, almost as if the sound hurts them? they will cringe, or shout at you, and at the very least not want you to do it again! what causes this?

I thought about this a couple months ago, and I think I'm ready to show this to public. I've figured out how to (theoretically) teleport to other places. Note this does not work with Living beings, you'll see why in a second. So my idea is, if you can separate the atoms, send them to another location, and then reattach the atoms, you can basically let one object teleport to another. It's sorta like TV, when electrons get separated, sent thru cable, then gets reattached (or beamed) to the screen. Now here's why you can't do the same with living things (if you didn't get it when I explained the theory), the atoms have to be separated one by one, which means it will be kille…

Hey all, I've been thinking about this for a little while, and my searching around has brought me here. This seems like a great forum! If I were able to teleport, what would happen if I teleported to a higher elevation? For instance, I live near sea level (around 400 feet above sea level), what would happen if I teleported to a mountain at 10,000 feet? Would I experience the bends or something similar? On that matter, how quickly are you able to safely ascend to higher elevations?

I guess this is more of a philosophical thought than it is a scientific thought, but its something I was discussing with an inferior mind earlier today.. Lets say we have a machine that reads all the atoms of a person, sends the information over some sort of medium where a machine on the other side reconstructs the atoms with the "blueprint" that came over the line.. Lets also assume that the machine that sent the data deconstructs the original atoms and stores them for later use (another teleportation or something). Two questions: Is this teleportation? Why or why not.. Is the "teleported" person the same person as the original? Why or why not. I argu…

So I’ve been playing this cool space travel game and Out of no where I had a couple ideas pop into my head on the game I was trying to find as many earth-like planets as I could and I found out that other scientists have been trying to find life on other planets as well so I thought maybe instead of searching the universes so aimlessly we could narrow down our search for other earths by looking at universes that have suns with same temperatures color and sizes as our own sun. I had another Idea as well constructing a rocket engine that’s capable of releasing all of the rockets fuel at once I thought this could maybe make rockets travel faster than normal what are your t…

What is the highest(heat) possible temperature? It's interesting that while the lowest possible temp has a value(absolute zero) even though it has never yet been reached. What about the highest or hottest temp possible. The biggest number I've seen is 100Million degrees C, or are there even higher temps?

I did measure the temp diff. in my fridge at the bottom and on the top. I got 11°C and 6°C. The problem I have is that I find that a big difference if you know that most things come with the text 'store at max 7°C' So my obvious question is why have fridges no build in ventilator. Only a small one so the temp is equal. The height diff. was about 60cm with still about 10cm room left above and below. Maybe it's a strange fridge, what are your fridge temps?

I am doing an investigation on to find the relationship between the temperature of the surface of the bulb with its power. Can some 1 tell me how the graph of this relationship would look like thank you

I read that in the desert, temperature inversion happens mostly on hot days. Why? The desert sand warms quickest, and so has the lowest heat capacity, so should absorb less heat than the air above it does. Why not? Sand normally has a specific heat capacity of 800 joules per kelvin per kilogram. Air normally has a specific heat capacity of 1000 joules per kelvin per kilogram.

Why is temperature measured in degrees just like rotation(360 degree circle) is measured in degrees. Do the two have any relationship?

Hey, I had a question that i cannot for the life of me figure out, and this is how it goes, "1. Find the amount of kinetic energy (joules) of the earth's Atmosphere" So i know that temprature is the measure of the kinetic energy that molecules are giving off at a certain time, or something to that extent But I cannot figure out how to convert lets say an average sunny day temprature into joules, if anyone knows how i can do that or if my whole train of thought is off, please tell me Here are 2 other questions that go along with it, 2. Find the kinetic energy of a moderate hurricane 3. Find the latent heat released by 5cm of rain over the state of G…

Does anyone know the current temperature on the top of mount Mckinley in Alaska?

There are some who consider language a scientific subject. Certainly it can be very technical. You might enjoy "The Cambridge Encylopedia of Language." I believe you can get a pdf download for your E reader. Tenses: Some languages (Latin, German, ...) use changes to the endings of nouns to indicate different purposes. English does not do this very much. Most languages (German, French, Latin, Russian .. ) offer a much smaller set of changes to verbs than does English. Although there are only three basic tenses, Past Present and Future, English has many variations on each. These variations often confuse those learning English as a foreign langu…

A component in a car suspension system is subjected to a tensile force of 20kN. The component is manufatured from a hollow steel tube of externel dia 25mm and wall thickness of 4mm. The modulus of elasticity (E) for the steel is 209 GN/m squared. a/ calculate the cross-sectional area of the component in mm b/ calculate the direct stress on the component in MN/m squared c/ find the direct strain on the component. d/ if the component is 30cm long calculate the change in length of the component under the applied load. give answer in mm. e/ if the yield strength of the material is 420MN/m squared, calculate the factor of safety for the component. Could someone ple…

Ideas and strategies for terraforming mars. I have no serious backround in sciences above high school level but I had several ideas for terraforming mars and I would like any one with knowledge to the contrary of my ideas come forward so that I may know and adapt my ideas. 1) My first idea is that to increase the amount of gas trapped in mars's atmosphere we must increase the gravitational pull of the planet by increasing it's density, to do this couldn't we put a material on mars that is very dense that will increase of mars but the mass much more. I think this would increase mars's density and its gravitational pull so that it would hold more gases in and create…

Don't laugh, I know how hard it's supposed to be to do this. Wanted to know if anyone had any ideas other than "haha you idiot mars is easier." Because frankly, I've been doing the math and it strikes me that Mars is not easier, and will in fact take much longer, and its biosphere would be much more fragile. My hope is that the idea will intrigue someone who may want to help with the math as a bizarre hobby :3 That’s not to say I haven’t done a lot of math already >_< *brain pain. The Goal: Transform the Atmosphere The Venusian highlands shine in the radio spectrum because of high compositions of pyrite (iron sulfide, FeS2). These two massive continents…

I am not sure if this is the appropriate place to post this. I have been into Tesla coiling for 4 years or so now. I just recently revamped my medium sized Telsa coil so it would be much more efficient. I just need to know if anyone here can help me about HV capacitor advice. Here are some pictures of my capacitor. http://s515.photobucket.com/albums/t360/tealman535/Tesla%20Coil/ It the right value and everything I just need to know if anyone here believes that the leads are perhaps too close together. The top and bottom leads are in direct connection with the the HV Transformer. So there is potentially 15kV at the left and right of the capacitor. I hop…

I need to test this gauge. It reads -0.25 to 0 to +0.25 in water. Im using it in the 0.02 to 0.03 negative and positive ranges. What of known value can I use to deflect this gauge maybe .1 or .05 in either or both directions to test the gauges accuracy? pa

I have a rock that I found that i think may be a meteorite. I am not sure, so i want to test it for iron and nickel. Is there any way i can do this with household items. Any ideas will help.

Without any professional device, is there any way to have a test or wild guess on whether a piece of gold jewelry is made of pure gold (i.e. 24K) with little or no impurities? And how reliable will that be?

I'm new to microbiology and am wondering how I can start to test the lifespan of yeast in as crude a way as possible. Any help would be appreciated. I don't know where to begin. I basically just have a microscope. It appears a lot of people talk about testing, but it is very difficult finding information on how to test without expensive equipment, a micro manipulator or some device to check light diffraction.

This is a thread where you can post things you want in science. For example, you can give a description of a book you are looking for, and other users should recommend one. Other things you can post here that you want include magazines, videos, websites, chemicals, or anything that has to do with science. Remember: it has to be in science. I was going to suggest this as a much needed new forum, but I think a thread will work just fine. ============================= I'll start. I would like a very complex book on the climate change. It needs very small details, and a lot of them. If anyone knows of a book, or even an article, meeting these requirements ple…
