There would be no point to having robots that can feel and express emotions and are free willed. Why would mankind make something that will compete with him? That would be illogical. But given that mankind's intelligence can and has not only produce some really amazing work but can produce...

I thik you may be thinking this system provides light at night. Not so. There is no formula. The bottle simply transfers sunlight into dark areas, the water within helping to conduct the light falling on the exposed top of the bottle. The light is refracted through the water, and exits within...

We were out looking for a new car a couple of weeks ago. It was a hot day. The salesman tried to sell us a black car. I said "Too hot!" He started to tell me "no difference". So, as there was a white car right alongside it, I had him feel the roofs of each in the same approximate spot. He backed...

Such could be achieved by employing Peltier effect technology, but there must be a temperature difference for it to work. The output would be very small, regardless.

At speed, the bike wheels are developing considerable centripetal force. They act like a gyroscope. It becomes rather hard to make the bike change direction, actually!

No, it's not perpetual. Like any machine, there are frictional and air drag losses. In a grandfather clock, the purpose of the weights is to provide a force to supply enough "push" on each oscillation of its pendulum (as well as drive the hands), to offset or exceed those losses. It then swings...

No picture, no answer. It's for mains operation, and consumes or outputs max. 4 watts. At this stage, only you know what it looks like. Did you ask your parents?

Measurement of statistical temperatures are done in the shade, in an open area, in a specifically sized and ventilated enclosure at a set height above ground and over grass. If you put a thermometer direct in sun, it will read too high. 4 fits best.

Buy a terrestrial eyepiece.

In a perfect vacuum and clear of any other interfering force, there is indeed nothing to stop motion of an object, so it will continue to move in the direction and at a velocity at which it is started out at. However, if you applied a force to slow it down or change its direction, it will either...
