As local ACS chair in 1999, I got to host the banquet when Alex won the Cotton award. The night's highlight for me was talking with him about music, where his knowledge of course put mine to shame. Every time I tell undergraduates about Borodin and the aldol, I think of him.

I guess I understand why Kamala Harris only talks about her mother, Shyamala Gopalan, as a mother, but there is something missing, almost disrespectful. Because Shyamala Gopalan was an awesome scientist. And science was clearly a great passion to her.

imagine how she managed it. Science is hard enough with every advantage. Gopalan was cranking out beautiful work with usually a single student coauthor.
Gopalan got her Ph.D. from Berkeley in 1964, after moving from India and starting grad school at age 19! I don't know but

but I interpret her early career moving from Illinois-UC to Madison to Jewish General Hospital and McGill as her pursuit of the best opportunity to do her science. This was not somebody who just wanted a job. Ultimately LBNL let her be an NIH PI and do her best work.

Five curved arrows at once is not a mechanism. It is a conspiracy theory.

Getting it out in 17 months was an absolute miracle. There is a long list of chemists in Pharma who in a fair world would be hailed as heroes. I salute them.

By, uh, letting him blast nonsense about areas where he knows nothing?

A short science lesson. The histogram of murders vs year in Springfield is indistinguishable from random noise. Any interpretation of this data is the equivalent of seeing a dog in the clouds.
For comparison, the graphs I show below are based on a random-number generator.

So where did he get βmurders are up by 81% because of what Kamala Harris has allowed to happen to this small communityβ?
His team says he was comparingβ¦the 2023 # (9 murders) to the 2021 # (5).
Thatβs an 80% increase. But, uh, many issues here: cnn.com/2024/09/20/politics/β¦

for any interpretation of any kind. Small data sets provide ample opportunity for cherry picking (and cherry picking is a long-favorite way for people to lie with the 'truth'), but even if you are trying to be truthful, you probably need 100x as much data to say anything.

Oh, a related story that I tell: there is a graph in the Jurassic Park book that is completely LOL for anyone who has made a histogram from real data. Crichton liked to pretend he knew science, but actually doing it makes a difference.

Great paper on something that I think is an important factor in organic teaching. "Instructors can best address shame experiences in their courses through actions to acknowledge, minimize, and mitigate such experiences."

Excited to see this in print! Check out this work where we investigated students' feelings of shame in an organic chemistry course with @Jeff_Raker and colleagues! pubs.acs.org/doi/10.1021/acsβ¦

Just noting that Kamala Harris's mother, Shyamala Gopalan, was a terrific scientist. Grad school at 19, PhD Berkeley at 25 in 1964! Here, she is first and corresponding author on an excellent and highly cited PNAS based on an NIH grant with her as PI.

SchrΓΆdinger's cat
RPMD for tunneling through a 0.2 kcal/mol barrier at 10 K, forming the anti-Markovnikov product from BH3 propene.
The part that freaks me is how long tunneling takes, literally hundreds of fs with the H spread out on both sides of the barrier.

This is stunning. I collapsed it into one image for sharing. It deserves it. Colin Cowherd has approaching 2 MILLION Twitter followers and was MAGA until 2 years ago. People should share it with RW or uncertain friends and family.
