 It is impossible to be grumpy about anything when eating biscotti made by one's beautiful wife, drinking tea sweetened by one's own honey, warmed by a wood stove, and with a dog asleep on one's foot. Simply impossible. - pfreivald [more] |

Re: A Physics Quiz of a different type
Particle "A" is traveling at c/2 in the +X direction in inertial reference frame XY. Particle "B" is traveling at speed c/2 in the -X direction in the same reference frame. See Figure 1. In a second inertial reference frame X'Y', particle "B" is at rest. How fast is particle "A" traveling in this second reference frame? See Figure 2.
