If the 'average' intensity of direct sunlight on a warm summer day could be re-produced in a full spectrum light bulb, how many watts would that bulb be? I'm trying to find a bulb I can use to calibrate a photo sensor to sunlight intensity but my shop is on the base floor where there are no...

ah, my mistake. I was mixing up two articles. I was confusing spin with putting an electron into a superposition of two states of density distribution. This is what I meant to refer to: http://www.sciencedaily.com/releases/2007/11/071101144942.htm "Researchers Katja Nowack and Dr. Frank...

Then how is it that spin can be induced in an electron by lasers? Would that not suggest that the energy of a stream of light particles can send an electron into a spin?

Yes, light can be slowed down. In fact, the technology to do so will soon be found in a silicon chip. I just found this out about 2 weeks ago: http://news.harvard.edu/gazette/1999/02.18/light.html http://www.sciencedaily.com/releases/2008/03/080327172255.htm

I must have been smoking crack when I posted that, hence the edit. Yes, every instance of positive electron should have been proton. As for the paragraph that made no sense, let me clearify by explaining the application. I'm trying to figure out how to make a device that would allow someone...

Scenario: If a human body is fully charged with positive electrons (protons/lack of electrons) and comes in contact with a pool of positive electrons such as a charged plate, the charge stays the same in the human body and the plate. Now if the human comes in contact with a source of negative...

Interesting, I just started learning more about plasma yesterday, I wasn't aware there are different types. My thought was that considering plasma is both electrically conductive and reactive to magnetism, perhaps it can be used in future sensory components, such as magnetometers and pressure...

Have you ever seen an AC battery? It's much easier and cost-effective to produce a simple AC/DC converter in a wall wart than it would be to convert a DC battery to AC. Since the days of the transistor, DC has been the desired form of electrical power because of the constant current required to...

It would be an oscillating ultrasonic wave. Also, if the air within the balloon is a different temperature than the air outside of the balloon, how would this effect the result? Is the pressure of gas relative to temperature?

The basic set up would be to emit an ultrasonic wave through a balloon with a receiver on the other side (or the same side), and based on the observed alteration in the received wave form, phase shift, amplitude, rise and fall edges, etc, be able to determine the pressure within the balloon...

If you had an ultrasonic transmitter and receiver mounted within a pressurized container, what would happen to the wave signal as the pressure is changed within the container? I understand it's all just air moving, but would there be any obvious change to the ultrasonic wave as the air pressure...

There are UV curable materials, but they would only get harder with more light introduced (until fully cured).

In essence, yes. But not directly, I think of it more like if you had so much force pulling an incredibly strong vacuum, how do we know that there's not some unmeasurable change in the space inside. If there is no effect at all I'm going to be dissappointed, because I still think there is plenty...

When I was thinking of 'energy' I was thinking alive energy. My bad.

It does make sense, it's just not correct. I understand what is being asked, do you not? Okay so you're right, rotating the sphere won't expand it, but if you could expand the sphere and increase the vacuum so much that it did have an effect on the space inside, how would that be measured.
