Oh, goody, a chance to discuss one of my ‘spare time’ specialist subjects!
Dynamite is properly a tradename originally owned by Nobel’s Explosives and
consists of nitroglycerine stabilised by being absorbed in kieselghur (a type
of absorbent clay). It made Alfred Nobel a very, very rich man.

I'm going to get pedantic here. TNT is 2,4,6-trinitrotoluene. Dynamite is

describing other chemistries, but the technically refer to a specific

Not the answer, but may be useful:
4,184,000,000 J = 1 ton of TNT
For a comparison of energy in dynamite and gasoline, and for "The nonsense
about gasoline and dynamite," see:
Assume reference is to nitroglycerin; approximately 1MJ resultant release for
construction-style (25 cm/200gm) stick.
'Gasoline' is not determinate but can probably be found in CRC.

I believe the references are 15.3(k) and 15.3(s).
As to “confused yet”, I have been in that state ever since I started EMC work
30+ years ago. :(

Hi Sir,
I have a question for ESD Testing. For some reason, the electrostatic charges
shall build up on the EUT during the testing. The Buildup shall affect the
performance of EUT or the testing itsself. How to evaluate the effectiveness of
this Buildup of electrostatic charge? Is there someone
