Coulomb 4.0 is here, via @temblorinc.bsky.social! What's this, you ask? It's the latest version of an open-source Matlab program that can help you visualize how stress is transferred when faults rupture. Find out more in this article by the scientists that developed and refined it! ⚒️

Yesterday, I had the honor of giving my tenure talk to the Purdue EAPS department. I won’t actually find out if I was successful until next spring, but no matter what, I am incredibly grateful to have had the opportunity to be a faculty member here and thoroughly enjoyed the last 6 years. #boilerup

Do you want a big overview of NSF, explaining things like the fact that 24% of all federally funded academic fundamental research comes from NSF? And that 94% of its budget goes out the door in grants/awards? Here you go. nsf-gov-resources.nsf.gov/files/Factsh...

An “NSF BY THE NUMBERS” fact sheet screenshot with some facts about “ADVANCING SCIENCE AND ENGINEERING RESEARCH IN THE U.S. AND ABROAD”

-The U.S. National Science Foundation was created by Congress in_ 1950 to continue the U.S. science and technology enterprise began during World War II.
-NSF allocates 94% of its approximately $8.5 billion budget for grants and awards to support research projects, facilities and STEM education.
-NSF funds research in all 50 states and U.S. territories.
-NSF fosters international scientific collaboration on all 7 continents around the globe.
-About 2,000 academic and other private and public institutions across the U.S. conduct NSF-funded research.
-NSF supports 24% of all federally funded academic fundamental research at U.S. colleges and universities.
fundamental research comes from NSF.
- In 2020, NSF received approximately 43,000 research proposals from scientists and engineers and funded about 12,000.
- NSF-funded researchers have received 248 Nobel Prizes.
