Now, here is the funny part...

On January 23, 1950, Einstein wrote in a letter".. I have never taken
 part in work of a military-technical nature..."


Albert Einstein was always very careful with 'words' he used so he can
get out of it.


".. I have never taken
 part in work of a military-technical nature..."


"in work"????


Is that like the opposite of "out work"?? Or what 'out work' means
today...remote work?


So, he is saying "I've done remote work of a military-technical
nature..."

The Starmaker -- To question the unquestionable, ask the unaskable,
 to think the unthinkable, mention the unmentionable, say the unsayable,
and challenge
 the unchallengeable.
