Hope no rf amplifiers (which tend to be the first pieces of NMR equipment to go after this type of event) were harmed during this power outage…

Mohamed Sabba The main risk these days when there is a prolonged power cut is actually to dry magnets. They need electricity to keep their helium cold, or there may be a quench 😬

I have made it my lifelong dream to get a 187Os NMR spectrum + relaxation data for this molecular spin system. This is an excellent candidate for 31P inverse detection and I'd bet you good money you will find osmium satellites separated by ~300 Hz visible in the 31P spectrum...

It was an absolute honor to work with Dr. Harbor-Collins and share some of the delights of his outstanding work. I have no doubt that whatever he does in the future, it will be excellent.

The four terminating 8W7 representations of the q^{-1}-Askey-Wilson polynomials. These are a finite family of polynomials in x, defined by \bm{\mathsf p}_n(x;a,b,c,d|q):=i^{-n}p_n(i/2(z-1/z);ia,ib,ic,id|q^{-1}) and are orthogonal on the whole real line, x=1/2(z-1/z).

Wisdom from my wife: "You've been working for 10 hours straight. They only pay you to work 7 hours with a 1 hour lunch break." I guess I'll put down my laptop for the day...

The coefficients of Q(n) appear in OEIS A083061. "Triangle of coefficients of a companion polynomial to the Gandhi polynomial" oeis.org/A083061

How it feels when they complain your pulse sequence "doesn't work" but investigation of Topspin immediately reveals that every parameter was set incorrectly:

Thank you Yashiro for that low-field-MRI shim coil PCB you gifted me last month. It turned out to be the perfect mouse mat for my desk, a daily reminder of your wonderful projects. #nmrchat #science

Minimalist cartoon cover art for scientific journals. Aside from journals with no cover ;-), are there any other examples you know of? #science #nmrchat

This is the mercury fountain memorial to the village of Almadén, Spain. YES. That's a lot of mercury sloshing around. ❤️ Beautiful flowing patterns, splashes and droplets, tragic history and toxicity.

We mourn the loss of one of the founders of the QEC (Knill-Laflamme) conditions and one of the first to write down the five qubit code (aka the Laflamme code). errorcorrectionzoo.org/c/stab_5_1_3
