- The above comments seem to be attempts at humor, I think. Yes ,I

- reading high lately..It's only sarcasm , juvenile grade. Not bad though.
-
- Now ,which of you students knows what physical mechanism creates the
- infrared radiation? Is it
-
- 1. Resistance to current flow in an electric circuit
-
- 2. Reluctance in the magnetic circuit
-
- 3. Redundance in the comedy circuit
-
- 4. Eddy Currents
-
- 5. All of the above
-
- 6. None of the above
-
- 7. Some of the above
-
- Well kids, which one of you class clowns knows the answer?
