Do you understand friendly or basic fractions? like how 3/6=4/8=1/2 ?
Basically once you get an answer to a fraction problem you want to put in lowest terms.
Say you have 8/12. If we express that in terms of primes it is 2*2*2/2/2/3. Two of the twos that are multiplied cancel with 2 that are...
I can think of an proof using greater thans or less thans for an ordered field. For complex numbers I believe I know the outlines proof using properties of magnitude.
Obvious the statement isn't true for matrices. What at minimum do you need for the statement to be true? I'm thinking you may...
I've been reading a bunch of this debate. I'm not really able to understand all of the elements of the argument (engineering student with some QM), and excuse me if I'm way off base in saying this, but it seems that this in some ways this is a disagreement about philosophy. There is some give...
But the air flow was generated on the boat.
The fan blows the air forwards. This accelerates the boat backwards.
The sail catches the air and captures its momentum. This force is equal and opposite to the force of the fan.
I don't see how this is possible.
What are the E and m in the E^2 = pi*m?
"Pairs of particles." The wave equation is often derived using the model of a chain of particles all connected to their neighbors using springs. When he says connected as paris of particles he probably is referring to the fact that the equation assumes a...
after thinking about it you're right. I got confused. The speed of particles depends on du/dt and can -> 0 without any effect on the c^2 term.
Maybe the trick is when doing the hooke's law derivation of the wave is to compensate for the fact that the "springs" do not react instantly but only...
The question in the title. Speed of sound in a medium obviously must be less than the speed of light. Speed of sound is usually given by the equation sqrt(c/p). Wondering what causes this to always be less than the speed of light.
Gar. Just realized something as I'm typing this. Now that I...
