My University Sacrificed Ideas for Ideology. So Today I Quit. [repost]

source My University Sacrificed Ideas for Ideology. So Today I Quit. The more I spoke out against the illiberalism that has swallowed Portland State University, the more retaliation I faced.  Peter Boghossian 8 hr ago 490 181 Peter Boghossian has taught philosophy at Portland State University for the past decade. In the letter below, sent this morning to the university’s provost, he explains why he is resigning. Dear Provost Susan Jeffords, ​​I’m writing to you today to resign as assistant professor of philosophy at Portland State University. Over the last decade, it has been my privilege to teach at the university. My specialties are critical thinking, ethics and the Socratic method, and I teach classes like Science and Pseudoscience and The Philosophy of Education. But in addition to exploring classic philosophers and traditional texts, I’ve invited a wide range of guest lecturers to address my classes, from Flat-Earthers to Christian apologists to global climate skeptics to Occupy W

Humidity and airborne viruse (Linsey Marr @linseymarr)

. @DrWanYang and I studied this question in 2011, exploring different removal mechanisms from air as a function of RH. I thought we’d find that at high RH, droplets/aerosols would be a lot larger and settle out quickly. https://t.co/Lu9CQB1AMz /2 — Linsey Marr (@linseymarr) December 27, 2020 This led us on a 10-year quest to understand virus inactivation in droplets/aerosols, still ongoing. Survival can vary by 2-100x between <20% RH vs. 40-80% RH, usually U-shaped relationship between viability and RH for many viruses. https://t.co/gncwvtQpGF with @kaisen_lin /4 pic.twitter.com/Z93CqKnTbo — Linsey Marr (@linseymarr) December 27, 2020 SARS-CoV-2 shows the classic U-shaped relationship between viability and RH that we see with most enveloped viruses in culture media. https://t.co/lFovXAdUkr with @dylanhmorris @amandinegamble @qishenhuang @petervikesland Munster Lloyd-Smith others /6 pic.twitter.com/Ow057Qm77F — Linsey Marr (@linseymarr) December 27, 2020 At low R

Install WRF 4.1 in Ubuntu 19.10 - Solving the problem of libpng12 for WPS ungrib.exe *UPDATE

Assuming that you installed WRF on Ubuntu 19.10 following any of the tutorials , you will face a problem. Apparently everything went good, but when you run ./ungrib.exe, you will see an error. The thing is that Ubuntu has libpng16 and we need libpng12. In few words, following this https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?t=8561 Assuming that the file $DIR/grib2/lib/libpng12.so.0 exists, you could try: export LD_LIBRARY_PATH=$DIR/grib2/lib:$LD_LIBRARY_PATH
