Acronyms and other memory prickers
bonneyman:
Let's start a thread for all the interesting and ingenious phrases and tricks we use to prompt our memories of important facts. Perhaps if we get enough helpful ones we can make a stickie?
For instance, how do I recall the angles to use in trigonometric calculations? I learned "Same old horse came a hopping through our alley". Sine is the opposite angle over the hypotenuse, Cosine is the adjacent over the hypotenuse, and Tangent is the opposite over the adjacent.
Watching a video on caves, I recalled how I remember the difference between stalagmites and stalactites.
Stalagmites (with a G) Grow upwards from the Ground. Stalactites (with a C) Cling to the Ceiling.
I'll post more as they come to me.

Tites were at the top of the cave and mites were in the muck was how I learned.
goodfellow:
Here's one for the welders to remember Straight or Reverse polarity (with regard to electrodes and ground) using both houses of congress as a memory jogger
Senate = SEN = Straight Polarity Electrode Negative
House of Representatives = REP = Reverse Polarity Electrode Positive
Hence TIG welding is usually SEN, while stick welding is usually REP -- MIG can be both depending on what wire you use.

I simplify it even more, StalacTite. T as in "from the top of the cave".
