1 . is it true that some thing that turns on or off very fast or AC will make radio wave ? 2. modulation is way of putting information on the radio wave? 3. All things have a resonant frequencies ? 4. A resonant is some thing that vibrates when energy of certain frequency is applied to it. 5. A moving or changing magnetic field causes electric current. Note I'm trying find other ways to transfer electricity or cause electric current.I know electric current has magnetic field and magnetic field causes electric current . I also know there is strong relashionship of electricity and magnetism .

Something that might be of interest to those here... a National Geographic special airing on Sunday the 11th October entitled Dinosaurs Decoded. Here is a synapsis of the show: With stunning animation, Dinosaurs Decoded brings to life a vision of dinosaurs unlike any you’ve ever seen before. Groundbreaking work by famed paleontologist Jack Horner, Mark Goodwin, and others reveals dinosaur underwent extreme transformations as they grew. They sprouted and lost horns and bumps on their skulls. And males shed dull colors for startlingly bright ones. A young Triceratops or T.rex may have looked so different from its parents you’d have a hard time recognizing it. …

http://www.scienceforums.net/forum/showthread.php?p=511093#post511093 So what do you think, are economics a scientific field or not? I'm personally going to go with "god no". Economics is not empirical and relies too much on unpredictable human behaviors to ever have testable theories in the way you can in the hard sciences. I think the financial crisis proved very thoroughly that when you try to take scientific modeling and apply it to economics, what you end up with are not reliable predictions about the future.

Cool shuttle videos, Enjoy:-) STS-128 Mission Overview Discovery Arrives Back in Florida

Tiny houses are nothing new, in Japan they are big (no pun intended) but are often quite unpleasent. Other verstions of the idea such as caravans totally fail. I have what is probbably a new idea. Imagine a single room, the room has waterproof possible pool like walls and floor, nice for an odd shaped swimming pool but no use for a house. Across the bottom of one wall is something that looks like nothing but upon eximation opens into a slot with the edge of a carpet inside, pull at the carpet and it unrolls covering the floor clipping in neer the floor at the other side. You chose the color and style of this carpet on purchising the space and can for a fee have it…

I currently am a fiber installer for one of the largest FTTH deployments in the USA. I would be willing to help anyone understand what goes into deploying this wonderful technology. In return I ask for a challenging and thought provoking environment. Who knows, maybe we can develop new science and technology here on these forums. Every good product started with an idea. Thanks Victor aka VickFury agent of nothing

Anybody knows what the most popular environmental engineering jobs are? Thanks K.

Why do we dream? Seriously the question really bugs me! I'd like to hear your brilliant opinions!!

Would it likely be possible, if eventually as technology has advanced enough, that a human could turn his/herself into pure energy, and maintain consciousness and sentience, so as to be invulnerable to all or most of the dangers in the universe. As we understand it, our consciousness is a product of the electrochemical signaling between neurons. Now if we replaced each neuron, one at a time, with a non-organic human-made neuron that performs the same action, the data from the old neuron is always stored in multiple places in the brain, correct? So as we take one out at a time, replacing it with a man-made neuron, would our consciousness (who we are) remain the…

Hi: I'm looking for a part of the United States of America which best fits all of the following: 1. Least amount of wind 2. Furthest from the sea 3. Coldest temperature 4. Most humidity and water 5. Most flatland -- i.e. little or no mountain or hill. Which part of USA most closely fits my dream? I'd like to live in this area. Any assistance on this matter is greatly appreciated. Thanks, Green Xenon

Anyone here have an interest in the subject, or are experts in this field? I've had an interest in the creation of "Strong AI" for quite a while, and kept up with the research that is going on with it. Mind you, when I mean Strong AI, I mean computers that can actually think and have consciousness. There is some very interesting stuff and research going on in this field. In a show on Discovery Channel that I saw about 2 years ago, they described the various experiments going on in Japan and in MIT concerned with programming a computer to be sentient. Particularly in Japan, they are trying to program machines that have a genuine personality and emotions. In M…

I have started a geophysics thread. Anyone got anything they wish to discuss?

I once read about a certain mineral deposit, I believe somewhere in France, the molecular grid of which was influenced by the earth's magnetic fields at the time the mineral was formed. Because of this it was useful in paleomagnetism, as one could know from the age of the mineral where the earth's magnetic north was at that time. Unfortunately, I've forgotten how these deposits were called, and how the mineral in question was called. Anyone know what I'm talking about, or, if not, does anyone know how to find this information on Google, ie, which keywords to use? I've tried a couple, but didn't find anything about this subject.

Does anyone know if Jungle/Drum'nBass rythm is obtained by taking algebraic numbers, like the binary digits of Sqrt(2) ? It cannot by expressed as a rational number p/q, and hence there are no repetition...

Sources on the Internet say that the lowest air temperature recorded on earth is in Vostok station in Antarctica: −89.2 °C was recorded there. The −89.2 °C was recorded in Vostok station which is at an elevation of 3,488meters above sea level. However I'm not really sure that's the lowest temperature in the troposphere since at the top of the troposphere temperature may be even lower. My question is: Does anyone know what the lowest temperature recorded in the top of the troposphere or in the tropopause is?

Can anyone guide about this place,its location.And what type of research are the scientists doing on it?

Hey, out of interest, does anyone know of any science- related contests/ competitions (particularly in chemistry, biology, biochemistry, invention or general sciences(theoretical and experimental)) that a Canadian high school student can participate in? (Whether national or international (or municipal, if it's one of the larger cities ie. Ottawa, Montreal, Toronto, Vancouver) While I have specified some of my preferences I'm pretty open to anything that can be found. Thanks in advance, -theo ps: Age isn't an issue either, as I only begin next year, so I'm open to a rather broad spectrum.

Do you have any favourite science documentaries? It's your chance to promote your favourites, and it would be very helpful to me as well. I'm in the mood for a few good documentaries in any area of science to keep me entertained after work. I know that people on these forums would know which documentaries to watch and which are to watch out for. That is my main reason for asking. I don't want to accidentally watch something that will brainwash me into believing lies or seeing only half of the story. Thank you!

What's the maximum height a mountain can be on Earth? Mountain height is a combination of geologic forces reduced by gravity and erosion. No, say we have an early Mars-like world with just enough mass and water to develop plate tectonics, but not enough water to erode the mountains too quickly. How tall can they get? ten miles? thirty miles? etc.
