Horseshoe vortex

The horseshoe vortex system is a simple vortex model for an aircraft or lifting body which fits a box-shaped vortex system out from the wing. This is made up of the wing vortex, trailing vortices (see trailing vortex) and starting vortex. The latter is a vortex formed due to changes in the vorticity of the wing vortex, i.e due to changes in airspeed.
I can't honestly think of a good example for you. Sorry

Japan

1) World's second largest single economy (disregarding Eurozone).
2) World class producers of automobiles.
3) World class producers of small electronic gizmos with no readily identifiable use.
4) World class producers of animated tentacle-rape porn, disturbingly....
5) One of the few countries to feature vending machines with schoolgirl knickers in.
6) Has really perfected the *art* of toilet making. Music and automatic scent release, from a toilet shaped like a mouth? Fantastic!
7) Has the world's second largest defence budget, in real terms.
8) Doesn't seem to do much with that money. One can only assume that a giant robot godzilla is around the corner.
9) Limited land area. One can only ski for a short distance before smacking into the side of a cooperative bank.
Japan. An odd place to visit.

Collimating lens

A lens which focuses light rays from a source into parallel paths, thus focusing the image relayed at infinity. Highly useful in Head-Up-Display systems, for obvious reasons.
This will be the 2nd in my series of largely useless technical jargon, which will continue as it is more fun writing this than writing a report on the performance and aerodynamics of an MAV.

-For more amusing and less contrived definitions, look up my ones for France or Europe. They're OK.

Trailing vortex

The trailing vortex, also known, smewhat erroneously, as the 'wingtip vortex', is created due to the pressure differentials between the upper and lower sides of an aircraft wing. The resultant vorticity 'coils up' to form distinct trailin vortices, trailing from the wingtips. The assumption of perfect line-vortex systems from the wingtips is inherent in the horseshoe vortex model.
The trailing vortex was visible in the air.

Aha! There goes another useless psychologist!

emp

The EMP, or Electromagnetic pulse, is a rapid magnetic fluctuation which induces pulses of current in unshielded electronics. Natural sources of EMP include lightning, whereas artificial ones include a nuclear blast.

A nuclear blast generates an EMP via gamma radiation interacting with air molecules to create Compton electrons. These create a brief current and an associated electromagnetic pulse. This is especially hazardous with an exo-atmospheric nuclear blast outside the atmosphere, as the region affected by Compton electrons in such a manner becomes enormous and the electrons will rotate around the Earth's natural magnetic field lines, creating a vast pulse.

EMPs and NEMPs are extremely hazardous to unshielded electronics, causing rapid fluctuations in current, especially in long wires or antennae.
Yes, this might be something of an intellectual masturbation, but it's more fun than actually working. Hey-ho.

Evolutionist

-Doesn't actually exist. There is no such faction or mindset as an 'evolutionist', which has so far not prevented the more literal-minded creationists from leaping on the title.
Evolutionist. -A fine example of poor English topped off with a platform to stand on.
