One of the enormous advances in astronomy since my grad school days has been in our understanding of gyrochronolgy. Look at this amazing figure and reflect on the rich physics it contains about stellar spin down!

The paper is sufficiently short that I don’t think a summary here is needed, but I’ll highlight that this is part of a larger effort to fill the gaps in the gyro (rotation-age) sequence to get better ages for field stars.

When you ask me to serve on a review panel, and aren't willing to cover the cost of childcare, you are asking me to pay money out of pocket to do you a service. 🧪🔭 This is why I rarely serve on review panels.

I'll summarize this: Mamdani asked NYers to keep air conditioning at 78 degrees. A wave criticism hit online. A MSNBC broadcast pointed out the US Department of Energy recommends that 78 degree figure. Immediately after, the US Department of Energy deleted 6,000 web pages related to energy saving.

A version of this happened to us where the major hospital in the area (UNC's) got into a spat with our insurance and stopped taking it mid-year. When I called the hospital they suggested I change insurance. Me: "do you.. like... not know how insurance works in this country?"
