If Einstein's relativity tells us that movement is relative to the observer, and if temperature is determined in the following way, movement creates friction and friction creates heat, then is temperature not relative to the observer also?
A limit is the value that a function approaches (without necessarily being equal to) as x approaches a specific value.
A limit can only exist if the limits approaching from the left and the right both exist and are equal.
the analogy I've been going off is the idea of a force field or a...
E=mc2 gives us the cosmological constant, which later was found to be the maximum speed at which light can travel. i also understand that when accelerating particles such as they do at CERN, it requires more and more energy the faster u want to go, the mass/speed issue. so i think i understand...
"This is a complicated question. The simple version is to imagine two ice skaters on ice. One tosses a ball to the other one. The toss causes the tosser to move away from the other skater, and when the ball is caught the other skater moves away as well. So we have a very very simple analogy of a...
ok so a photon(s) is a family of particles/waves in a spectrum from radio to gamma. we see a small part of this. but when we see things, the only thing our eyes are detecting are photon waves in the visible range, right? also if photons, as there are so many of them, are mediators of the EM...
Photons seem to play an enormous role in not only our universe, but also our daily lives. from my understanding our eyes are just photon detectors... It also acts as the mediator for the EM force, is one of the few particles that can reach the cosmic speed limit, distributes heat or energy...
what I've so far what managed to gather is; that a classic field is a way of describing "action at a distance". A quantum field makes use of quantum particles to help explain the distance part, thus making things even more complicated.
4 main types of fields, scalar, vector, spinor and tensor...
So I guess that in the end the Drake equation holds a lot of value in that it is giving us a reasonable estimate based on the reliable information we've so far managed to gather.
One thing i'd still like some clarification on though; out of all this I'm getting that the biggest problem with...
If some one could please explain what a field is in as much detail as possible please. don't be shy I love a challenge.
My understanding is that a field is a precise area surrounding its source. depending on the field you get different effects. For example with the higgs field, the higgs...
what do you mean by reasonable? what about goldilocks zones for planets, or vital metals in the planets such as nickle and iron. I also think that stuff like water and meteors should be considered, as well as large planets like Jupiter within a system shielding inner planets from outer system...
Personally I think the equation greatly overestimates the number of possible intelligent life in the universe... But then again all I have is a college level education.
Can anyone explain?
Hey, I am self taught and by no means an expert, but have a decent understanding of the standard model. I am looking looking for a little clarification on what exactly a phase, or phase shift is. also perhaps a definition of what a dimension is... as i understand them, a dimension is movement...
So your saying there are two types of radioactivity;
the decay of atoms, or the weak nuclear force emitting radioactive particles such as beta particles,
and radionuclides which are unstable isotopes that are remnants of nuclear explosions such as chernobyl
In the case of the ground water...
It is my understanding that radiation is caused by the weak nuclear force, that its the decay of particles. if this is the case, then can some one please explain why after an incident like Chernobyl for instance, that things for thousands of miles in all directions are still to this day...
