My dissertation is now freely available: scholarworks.montana.edu/items/5f1522d5… It examines nanocrystal ligand effects on transport, lamellar structure influence on charge separation, and impact of noise in measures of excited state diffusion in semiconducting materials. �#chemskyk#perovskyky

Yay I got the bonus scribble! Amazing book.

Cozying up to kick off my birthday weekend with this remarkable new book by Toby Hendy @tibees.bsky.social. Look closely at the photograph: an inversion hides in plain sight! The fourth dimension may be closer than it seems…

Joseph Thiebes, wearing pajamas, holds the book “A Guide to Making Friends in the Fourth Dimension” by Toby Hendy, partly covering his face. An elephant sconce hangs on the wall behind him. A hallway extends into the background with a mirror that reflects light and his silhouette from behind.

But if I do a fit on two points, I get an R^2 of 1.0000000!!!

I’m starting a new position as a part-time Middle School Science Laboratory Instructor!

I’ll spend an hour each week helping students explore the scientific method, nurture critical thinking skills, and connect with the Montessori tradition of self-directed cosmic education.

From the glossary in my dissertation.

Let’s normalize calling it Meitner-Auger recombination, shall we?

Dr. Joseph J. Thiebes @thiebes.bsky.social · Jul 27

Meitner-Auger recombination: A process by which energy transfer between excitons causes one to recombine and the other to be excited to a higher energy state within the same energy band. It was discovered and published in 1922 by Lise Meitner and—independently—in 1923 by Pierre Victor Auger.

Happy Tau Day!

We celebrate both Pi Day and Tau Day at our house. Tau (≈6.28) is 2π, and some say it is the better circle constant. Either way, it is a great chance to talk angles, radians, and geometry with kids. Preferably over something round and tasty. #TauDay

A cartoon illustration showing the Greek letter tau (τ) with a smiling face on the left. On the right, there are two smiling cartoon pies stacked vertically. An equal sign is between them, indicating that tau equals two pies. The background is dark blue.

There are always more people who can be argued to be “best qualified” than there are awards to give. Final decisions often come down to vibes, gut feelings, or familiarity. In that context, it’s not a band-aid. Ensuring gender balance is a way to check bias and expand who gets recognized.

Dr. Joseph J. Thiebes @thiebes.bsky.social · Jun 27

Every science award given to multiple people should go to half who identify as women and half who identify as men. For odd numbers, alternate yearly.

“Best qualified” is no excuse. There are always more qualified people than awards. All-male award lists should be embarrassing.

Pão de Queijo! Easy to make:

170 g tapioca flour
1 egg
1/3 C olive oil
2/3 C milk
66 g cheese
1 tsp salt

Blend to homogeneity, 3/4 fill greased mini muffin pan, bake at 400 F for 15 min.

Spray the pan w/ canola oil because it is healthy and to spite RFK who hates it. #ChemistsWhoCook

A green plastic container filled with freshly baked pão de queijo (Brazilian cheese bread). The small, round pastries have a golden-brown crust on the sides and a soft, slightly puffed, yellowish top. They are piled together, showcasing their airy and chewy texture. The container sits on a neutral-colored surface.

The fact that the 95% CI includes no effect does not mean there is no significant correlation. The mean is above zero; did you dig deep enough to figure out what the confidence level would need to be for zero to be excluded from the interval?

None of these studies “make mice transgender.” The claim is pure nonsense. #transgender #DOGE #NIH 8/
