BlastMaster's definitions

radio

There are many different types of radio receiving circuits:
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne

Modern radios are superheterodyne. The superheterodyne circuit replaced the TRF and regenerative circuits by the 1930's, and crystal sets were nearly dead until solid state radio emerged.

si

Short for "System International." Also known as the Metric System.

The SI system makes more sense than the English system. It should be officially adopted by the US, but we Americans are too lazy for change.
