This potentially makes it suitable for the direct measurement of ultra long optical group delays because the group delay time for a pulse that propagates one attenuation length is approximately given by to the inverse width of ...

... Proof that momentum is conserved Now finally, we are ready for the proof that momentum is conserved in collisions. We are going to show that Newton's 3rd Law guarantees that (total momentum before collision) = (total momentum after collision) We will show that when two objects (A and B) collide, the ...

... Answer: 4. The golf ball bounces back at nearly its incident speed, whereas the bowling ball hardly budges. Thus the change in momentum of the golf ball is nearly -2mv, and the bowling ball must gain momentum +2mv to conserve momentum. However, since the mass of the bowling ball is much larger than ...

Molecular Nanomagnets: towards molecular spintronics Wolfgang
... Abstract: Molecular nanomagnets, often called single-molecule magnets, have attracted much interest in recent years both from experimental and theoretical point of view. These systems are organometallic clusters characterized by a large spin ground state with a predominant uniaxial anisotropy. The q ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
