11.Pointing the thumb of my right hand into the screen shows that the currents along the bottom of the solenoid cause magnetic fields which are clockwise.
12.Just like with classical waves, photons can be circularly polarized, and there exists polarizing filters that only let through photons that are polarized circularly, say in the clockwise direction.
13.If you walk around the great court in a clockwise direction on the west side, you'll see the entrance to the long hall of ancient Egypt which has an amazing collection of Egyptian antiquities.
14.First off, the convention in the context of Fourier transforms is to think about rotating in the clockwise direction, so let's go ahead and throw a negative sign up into that exponent.
