Happy Birthday Evangelista Torricelli!
-
Torricelli was the first person to create a sustained vacuum and to discover the principle of a barometer. In 1643 he proposed an experiment, later performed by his colleague Vincenzo Viviani, that demonstrated that atmospheric pressure determines the height to which a fluid will rise in a tube inverted over the same liquid. This concept led to the development of the barometer.

The saying, "Lite is just one damn thing after another," is a gross understatement. The damn things overlap.

I'm sorry, but that guy really sucked.

Which really sucks for Timothy D. Grizzly who invented the Bear-o-meter only 12 hours later. It measures the scariness of a bear by the volume of your girly scream. Even though the barometer and the bearometer are pronounced differently, the marketing team for bearometer never found a way to convince the public.

Getting into the weeds here, but although Torr and mmHg are pretty much used interchangeably these days, I was under the impression that there was a difference in context in addition to the small difference in measurement.
Torr, irrc, is a measurement which is context-independent. So, if your BP is 120/60 torr on earth, it's (almost exactly) 120/60 mm Hg.
However, on the moon, your BP would be 120/80 torr, but only 20/10 mm Hg.
I think I got that right - I haven't thought about this in about 30 years, LOL.

I've always found all of the various pressure measurements rather confusing, bar none.
Or should that be bar-gauge none?
I was only joking

@doctor-phibes Bear-none.

He looks as though he's drunk more than a few millimeters of mercury. It's made him psi-cotic.
