Greetings. I just want to understand heat pumps. As far as I know - they keep a house warmer than it could be using a regular electric radiator, using the same amount of energy.
I am wondering - if a heat pump outputs, say, 3 kW of heat energy from 1 kW of input electric energy from the grid (or...
Greetings. I thought about how/ why light propagates slower trough matter than vacuum. Generally it is excepted that it happens because photons are absorbed and then emitted by the atoms and it kinda makes sense. But I see other possibilities.
I propose and experiment:
How about shining...
First year learning programming here.
I am trying to write a line drawing algorithm that would be, perhaps, faster than algorithms used today (that would be nice, if I would turn out to be smart and accomplish something nice) so I wrote this piece of code (currently it only draws lines where...
Maybe, somehow.. the main question was about photons passing parallel between the plates, but this begs me to ask more questions along the line : Two particles (say, electrons or simply atoms(?)) in space would be attracted to each other not only by gravity, but also do to the [very small]...
Does Casimir plates prevent photon existence only perpendicular to them?
I mean, Casimir attraction arises from the fact that the plates prevent some wavelenghts of photons to exist in between them, so an imbalance arises and pushes the plates together, right?
But what about photons in other...
I am studying programming for the first year so I don't have whole lot of experience. I am interested in how to work with super-large numbers, numbers that are much, much larger then the included Int or _int64. I mean some 100, 1000 .. 17 million (largest prime) digit numbers. How do they do...
If I take Mercury's speed and apply it to the Earth (regardless of mass), Earth would rise in a higher orbit, longer period and.. slow down?
And if I then slow down the Earth again, it will drop back to the lower level, speed up and shorten the orbital period?
I am very confused about the fact that, for example, Pluto moves around the Sun much slower then Earth and is also much further from the Sun, so its period is way longer that that of Earth's..
if I want to increase orbital height, I add speed to the object I want to raise, no? How come...
The Star Trek warp drive, you know. Real world reserch is even made in the field. http://www.extremetech.com/extreme/164326-nasa-discusses-its-warp-drive-research-prepares-to-create-a-warp-bubble-in-the-lab
If gravity waves are supposed to propagate at c, how could the theoretical warp drive wave propagate at greater than c values?
I have heard and red and understand that space itself can expand (and warp? ) faster than c and, in fact, that will happen in the future when space in between...
And by "pausing" the system I don't mean doing anything mystical to the universe, but more like .. looking, measuring a moving system at any given point in time.
Hope you understand.
"Paused" physical system
Greetings, physicists and others, who just happen to understand physics. Something is bothering my mind again and I am hoping that some clarity will be given here.
So, here is what I am thinking: if I Pause any physical system and, a bit after, sort of press "play" to...
