In C/C++, void has additional meanings, in particular when using (void *), which really means a pointer to an untyped object. This pointer of this type...

Most physicists believe that gravitons exist, but they are nearly impossible to detect because they are incredibly weak. Gravity waves should be much easier to detect, but even with the most sophisticated instruments...

You could argue that their time would be better spent learning a useful language, like Romanian instead of Romulan. On the other hand, not all of life should be utilitarian. People should be allowed to play and explore things...

The fastest carrier known is light. No experiment, to my knowledge, has ever shown that it's possible to transfer information faster than this rate. Many physicists have proposed mechanisms using entangled photons to cause...

If we extrapolate our vision based on what we see today, the Universe is infinite, but we simply cannot know if it really is, or if we only happen...

If B is squished down, it will increase the pressure inside of B, but reduce the pressure inside of A, because B will take up less volume inside of A. If these are...

Time is thought of as a dimension, similar to space. In fact, in Special (and General) Relativity, space and time are bundled together into something called spacetime. Time exists, even in the absence of light...

I think it's the case that people who know this stuff (physicists) don't think that imaginary time (or space) exists in reality.

It's fun to play with and visually appealing. It's also free. Don't let the somewhat childish look of it deter you... it's teaches fundamentals of...

Believe it or not, that is the highest energy that the LHC can obtain - about 14 TeV. However, you have to remember that the force of that nerf...

If you change the speed of light, does that effect the charge on an electron? I'd guess it would because the speed of light is the result of two properties of vacuum - its magnetic permeability and electrical permittivity. As for the...

The Kelvin scale doesn't go below zero. Fri, 15 Jan 2010 17:49:52 -0800 http://www.answerbag.com/a_view/8611391 http://www.answerbag.com/a_view/8607215 can you fly east 500 miles turn north go 500 miles then turn south and go 500 miles and land the same place you took off<br /><br />Yes, if you start anywhere on the latitude that is 500 miles south of the North Pole. The thing that allows you to do this, as after traveling 500 miles to the North Pole, *every* direction from there is south. So you can just head in the direction of your starting point, go 500 miles and you...

You need to allocate memory for ptrj to point at, and then point ptrj at that allocated memory.

So even though the language may not permit directly returning more than one value, you can in fact return more than one...

After that brief period, about 14 billion years ago, time as been much more predictable, smooth and fairly flat in our neck of the woods (though it's still highly distorted around...

Eventually, the chair would decompose and no longer be a chair at some point. But that happens whether or not someone is watching it. This is sort of like the...

The only way I can see it working is that you'd have to start with your normal, organic brain, and over time you'd add more and more artificial elements into it, gradually transferring all operation, memories, etc. over to the artificial brain, and slowly,...

For example, 2 moles of Hydrogen plus 1 mole of Oxygen makes 1 mole of H2O (water).

The Sun doesn't have the same sort of magnetic poles like the Earth (or some other planets) do. The Sun's magnetic field is much more complex, has many poles, and goes through an 11-year periodic cycle of changes.

From what I've read, mass is the result of matter interacting with the Higgs Field. At least that's the prevailing theory. The existence of the Higgs field, and its force carrier, the Higgs boson, is still hypothetical, and it's hoped that the Large Hadron Collider...

The amount of work done in overcoming friction as the weight is lifted is how many joules?<br /><br />Well, force times distance give the number of Joules. So 10 newtons times 5.0 meters is 50 Joules. If it actually took 60 Joules to lift the mass, there was (60 - 50) = 10 Joules left over for something else, so you can assume, I suppose, that all of those Joules were spent in overcoming the...

An engineer told me once that the ballasts used to energize the lights consume more energy when turned on and off than the lights use if just left on until closing. True?<br /><br />The answer is a little complicated. Just looking at the energy usage, the trade-off comes about 20 seconds after turning off the lamp.

So subtract 1g from 3gs, and you get 2g&#039;s of additional acceleration. This means you&#039;d add twice your weight (or just 3x total). So 3 x 120 = 360. The answer is c.
