We do some things to save the world, and some to make the world worth saving.

Yes, true. Habit and history I guess. At least they are using units.

A pair of 99.9985 kHz crystals from an HP3571A spectrum analyzer, part of a 5-stage filter that set the IF bandwidth. They are simply gold-plated flat plates packaged like vacuum tubes. Made by Northern Engineering Laboratories, Burlington WI.

True. The good news is that Trump is old, sick, and unpopular. His sycophants are laughable characters with almost no political appeal. Maybe the whole mess will collapse quickly when dear leader returns to the underworld from whence he came.

Presumably a good MBA will know that 406 formulas they wrote themselves are correct. How can they know that about Claude’s output? Will they test each one?

For some samples, benchtop NMR at 125 MHz is equivalent to high-field NMR.

I hear Florida is going to make stopping at red lights optional. It’s your car! The government has no right to tell you how to drive it.

This looks like a nice benchtop NMR application πŸ™‚ @qmagnetics.bsky.social

Guv Jared Polis did an ask-me-anything on Reddit yesterday. It’s well worth reading. He remains strongly in support of vaccine access and is more critical of RFK Jr. than I expected. Unfortunately, no response about ICE building concentration camps in Colorado.

At 125 MHz, the benchtop NMR of 4-Phenylbutyric Acid shows methylene and aromatic protons. This compound is important in biomedical research, used as a chemical chaperone to treat protein misfolding disorders such as cystic fibrosis.πŸ§ͺ #NMRchat #Chemistry #flowchemistry #benchtopnmr

From a 1960 book chapter by James Schoolery. Back in the day it was CPS=cycles per second and mc=megacycles, and there was always carbon tet if you needed a β€˜deuterated’ solvent

I don’t really belong in this conversation, but… would it be a straightforward thing to measure the occupation of the alpha protons versus pH by proton NMR?

I think it’s very unlikely that these are flutes. I don’t know of any musical culture anywhere or any time that found such a skinny thing to be a satisfying flute. More likely they are reed instruments, like this: youtu.be/0_UEPpsCMCA?...
