I keep my dad's old slide rule in my office. Pretty sure my students think we were still using them back in the aughts.

We used melting experiments with meteorites and synthetics to show that parent bodies of O,S-rich meteorites formed sulfide cores through percolative melt migration. Evidence is preserved in diagnostic trace element signatures, and this process can also explain many aspects of the Martian interior.

As an igneous petrologist...
mr. burns from the simpsons is sitting in front of a painting and says excellent !

It's absolutely crazy... simultaneously sad, angry, and anxious about the future. Here for y'all, even if that just means feeling those things together for now.

Oh jeez! 2024 sneaking one more blow in before the bell... Hope Lee is feeling better now!

We collected individual images via third harmonic generationa, where the frequency of the laser is tripled through nonlinear interaction across changes in refractive index. This GIF shows a static video take through the middle, showing an air bubble interacting with the laser.
