@atweets_9 I've heard that one before 😂

Indications Iran was pursuing a nuclear weapon:
-Enriched Uranium to 60 percent with 3.7 percent being needed for any civilian usage.
-Iran developing Mazio ICBM launched economically unfeasible to put conventional warhead.
-Building of significant underground facilities as Isfahanm, Nantz and Fordow.
-Violations of the JCPOA agreement, violating IAEA inspections not giving access to certain cites, kicking inspectors off sites.
Why would you do all this to not develop a weapon?

In core-collapse supernova, neutrino fast flavor conversion
increases (decreases) shock revival & explosion energy for low (high) mass progenitors.

Its clear that Iran now sees control of the strait of Hormuz as good as the leverage an nuclear weapon would give it on the international stage...

Richard Feynman reportedly spent long hours, sometimes up to five hours, rehearsing lectures alone in empty classrooms before delivering them. It shows how mastery often looks like effortless clarity, but it is built in private repetition.

It was 🎉 paper day 🎉 a couple of days ago and I forgot I post about it. @itsizzyconnor and I led a study on understanding the Strouhal number from first principles in blast wave driven turbulence (supernova in a galactic disk): https://t.co/3ynlL3Onav

The same goes for a lecture I developed on how to derive macroscopic viscosity (and heat flux) by perturbing the distribution function away from Maxwell-Boltzmann. Take a look if you’re interested https://t.co/cDAgmMcoCK

[Dr. James Beattie @astro_magnetism]

Last week I taught a grad. class at UofT on constructing fluid theories from the Boltzmann equation, and finding the amplitudes of the eigenmodes for ideal MHD. I have uploaded my notes to my website, for those who might be interested: https://t.co/woFpDFLTfC

We're going back to the age when astronomy was funded by private patrons.

TACC has begun installing Horizon, the NSF’s new Leadership-Class Computing Facility supercomputer. Horizon is being deployed in Round Rock, Texas, and will become the largest academic supercomputer in the U.S. when production begins in 2026.

We should be developing thorium
