Suppose I want to gather with friends and buy a round or have a sector

Since 3/14 is not based on the

I'll buy you 0.1415926... of a pint if you come over here on that day.
That should make a complete pi of you.

Surely you jest. Most of us wouldn't walk to the fridge for 0.1415926 of
a pint. Maybe it is a decimal point problem. 31.4 pints would probably
have anyone pi

Has anyone here watched Big Bang Theory?
I think it's one of the cleverest sitcoms ever to come out of the US.
The science in it is accurate - verified by a university professor.
I just love it.
Any other comments?

I don't know of it.
Is this US network

Does anyone remember much about the old Motorola Oncore UT GPS receivers?
I have an HP Z3816a GPS timing receiver. I've been meaning for a long
time to add a display for UTC time to it for a while. Today I finally
got that project built and installed, and it works as intended, but I'm
seeing
the unit and see if the header
connector he used works. I though I looked at that, but it has been a
long time. Worth another attempt, I guess.

I'm puzzled. I admit that I don't have a lot of experience with
Rb standards, but I do have a bit of experience with the HP-5065A

your experience with the hot bar is quite common.
Sounds like a pretty reasonable manifestation of the Leidenfrost effect.
The water in contact with the hot end of the bar vaporizes, and the
resulting steam layer (which might be microscopic) does a good job
