Italy invented the compass. The pointer of the ancient Chinese compass was as big as a spoon. The spoon was put on a board, with nothing else. Compass, Wikipedia History of the compass, Wikipedia Chinese Compass, "Si Nan", photo.

The basis of learning everything mathematical and scientific being the number one, always learned by trusting someone (faith), the next being the number two, learned again by faith, at what point should a person discard faith? The best answer, that I think I can fairly project, is that a source should be discarded, as far as being trustworthy, when it fails "to work." I would ask then, are there ever any instances (and I think this can be fairly tested either by informal, or by formal observations) of Biblical faith, specifically, being both practical, and enriching in ways similar to or exceeding music, for example, for a person or for a group of persons? If the…

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'm currently working on my final design project at uni - designing a wearable cooling device for very humid conditions (e.g crowded rock concert), which would be worn on the wrist. I'm proposing to use an umbilical system, which means (from what I ..umm.. researched) that i need a reservoir, pump, cooling device, heat sink, power source... From what I understand, the temperature of the device needs to be kept above the dew point to minimise condensation. My challenge is to somehow fit all that inside a wrist band/cuff and to use a motor (Wellington Motors - they are special) somewhere in the device. The other option that I have is using a series of inbuilt Sunon mini-fa…

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)

Hi I am new on this forum. For my science fair, I am considering devising ways to keep carbonated, bottled (soft drinks) from going "flat", or, basically losing the bubbles. So, for my question. Do you guys have any ideas, or things that I can do?? It can be anything, but preferably not too complicated, and possibly somthing I can engineer or build. I look forward to hearing your Ideas!!!

Hi, I'm only 14 years old so excuse any spelling. I personally think gravity is caused by heat, not spinning. First off, The sun is holding the galaxie together because the planets are moving forward and the sun is bringing us into them with its gravitational pull, the sun is extremely hot and it has a pull. Second off, Earth is spinning(which some people think gravity is caused by) but we have a core that also contains extreme heat, we are pulled into it. If gravity was caused by spinning the people on the sides of the earth wouldnt stay. Third off, Space is extremely cold and it has less gravity. Forth off, A spaceship was flying away from the sun and all of the s…

At times, I hear this funny, high pitched ringing sound in my ear. What is it? What is causing it? It does NOT happen when i hear a loud sound.

On researching and following up some of the links posted in this Forum, I come across papers that are written in a way that is impenetrable to the casually interested. I will accept that papers are written for fellow specialists who understand the terminology. However, why write the papers in such a mangled and high-fangled way? I am as guilty as this as anyone else. During the writing of a paper, my supervisor changed the words of my original paper to make it more 'high' sounding and insisted I use the word 'moeity' instead of one of a pair of molecules and 'ablate' instead of 'broken down'. Being as dumb as an ox (and twice as ugly) I did not know the meaning …

I always believed that evolution was a completely random, undirected process, simply the result of random mutations and chance events. But then I read about the 'Infinite monkey theorem' experiment: “Given fifty-eight possible keys, it would be 58 x 58 x 58 x 58 ... fifteen times over, which is about 283 trillion trillion attempts. But remember we have a million monkeys working, and let's say they type forty-five words a minute, so the fifteen keystrokes that make up the phrase take just four seconds. And they never rest or sleep. How much time, then, according to probability laws, before one of them finally types, “Call me Ishmael”? Answer: about 36 trillion years…

For several hundreds of years important statements in natural sciences were called "laws". But some time ago new "laws" stopped to appear, and the important statements now seem to be rather called "principles" and "equations." Is it so? If so, what was the last "law"?

Today, faf-the-great turns 20! HAPPY BIRTHDAY! PARRTTYY!!! obligatory gay spiderman dance

I didn't know if this would go under Computer science or Mathematics...Oh well... Ok, you all know that the Ohms Law states Ohms=Volts/Amps; Amps= Volts/Ohms; and Volts= Ohms*Amps... Well, say one tries to run 5v through a wire with 0a...What would the Ohms be?...General Mathematics would say it is not possible, seeing how one cannot divide by zero, seeing how zero times anything is zero...With zero itself as an exception...Well, me and a friend have come up with that since the current of the wire is zero, than the resistance, (Ohms) must be indefinite, absolute, and furthermore, infinite...Thus, V/0, seeing how the number of volts is irrelevant, would equal infin…

Hey, I'll be in an upcoming school debate over wether video games decrease literacy rates or not. Does anyone here have a degree in psycology, or any other applicable science? If so, can I have your opinion? (Dont get me wrong, I've got nothing against video games.)

I have a few questions that relate to the whole topic of global warming/climate change theories. Please note that I am not looking for political answers, just scientific fact (that's why I'm here after all). Also I wasn't too sure where to post this thread (It is a chemistry question, but it involves climatology and biology as well). Currently the most widely accepted theory on global warming is that greenhouse gases (primarily CO2) are a major influence. Through biology we know that vegetation converts CO2 into O2. Is there any place on Earth where the CO2 concentration is higher, or where the stuff collects? Have there been any experiments or attempts to sy…

I have made with "Visual Basic" a [10*10] ChessBoard with 2 twins-Kings and chesspieces that: (1) they move and play like their images... and (2) you have 3 Basic "simple pieces" ( the soldier-Rook & the soldier-Bishop & the Knight ) which you can "step-by-step" add together ( with the Help of Transformers-Buttons ) to make 29 more "complex pieces" !!! ( you can separate them "step-by-step" again !!!... ) ( 001 = 3 = "soldier-Rook" / 010 = 5 = "soldier-Bishop" / 100 = 7 = Knight) - ( Each chesspiece has 2 Numbers !!!... ) Example: ( Addition: 001 + 010 = 011 / Multiplication: 3 * 5 = 15 ) ( The "011" shows how the piece…

ran into more problems with reasoning out the attached questions. can anyone solve these and pls state how u get to ur answer. thanks.> Reasoning.doc

I know many scientist do not believe anti-gravity is possible. I just wanted to know what you folks thought of this. Do you think they are really talking about anti-gravity, or using strong magnetic fields to 'levitate' the craft? http://www.cnn.com/2003/TECH/09/05/wow.tech.black.world/index.html "(CNN) -- What ground-breaking new technology is kept so secret by the authorities that even to comment on its existence would be to reveal too much? Welcome to black world technology -- the discrepancy in the defense budgets no-one can explain, and the programs which politicians and officials have the right to deny even exist. Yet it is big business, not j…

A science crackpot makes foolish claims with nothing to back them up but their own certainty. They're usually convinced that their lack of formal study makes them uniquely capable of seeing the truth through all the academic clutter most PhDs are saddled with. We're always hopeful crackpots can be shown that science isn't what they think it is. With this in mind, I want to start this thread where you can post examples of crackpot thinking you encounter here or elsewhere. A couple of rules. No attributions, please. Remove the names, we're not looking to embarrass anyone. Also, where possible or needed, point out the flawed thinking and possible causes. I'd like th…

Since mid 20th century, Psychology tries more and more to become a "real science" recognized by all members of the scientific community. Do you think this is a possible venture? What makes science what it is, can Psychology call itself science?

Ah, ah, ahrrrrggggggggggg http://www.sniksnak.com/aavs3.html For why? Why?

I remember watching a programme, where they stated that a fly experiences huge dilation of time. For example if you moved your hand slowly towards a fly it would percieve it as motionless. How is this possible ? As humans, events can seem shorter...if we're enjoying ourselves, or longer...waiting for a bus for instance. We certainly don't see events visibly slow down. Is this just down to the speed visual information is being relayed to the fly, like high speed film ? I keep on wondering if this has any implications towards relativity...if events are slower to one life form, how do they fit into the frame work of another...obviously they do, but it's kind of bug…

Sorry. I really have no idea what is metabolism about. I think it is something about chemical reactions but i am not really sure about it.

This is my first post here, so don't be too hard on me. I had an epiphany the other day and would like to share it with you guys & gals. Feed back on my theory, good or bad is, welcome. Assumption 1: The Earth's magnetic field swaps poles frequently in terms of geological years (10,000 - 40,000 years). At least that's a theory that I read. Assumption 2: As the magnetic field breaks up and moves away from the poles towards the opposite poll, more and more radiation penetrates the Earth's atmosphere. The Earth begins to heat and as the fields reach the equator position; the polal region is most exposed to radiation causing melting of the ice caps and a se…

Their education is nonexistant, their methodology laughable, and all of their interpretations wildly distorted by predetermined conclusions. But they put so much effort in to it, and spend most of their time furiously trying to poke holes in established science. Are there any mainstream ideas you guys know about that originated from those people?
