AP Photo/Andres Kudacki Topics: Applied Physics, Diversity in Science, Physics, Physiology “B-boys and B-girls wield physics to pull off gravity-defying dance moves.” Okay, “gravity-defying” is a bit of hyperbole. Break dancing, as the article alludes, started in New York, and the movements can be found in martial arts like Brazilian Capoeira. It’s more centrifugal forceContinue reading “B Boys & Girls, Physics & Olympics…”

Worrying trend Reliable climate models are needed so that societies can adapt to the impact of climate change. (Courtesy: Shutterstock/Migel) Topics: Applied Physics, Atmospheric Science, CERN, Civilization, Climate Change It was a scorcher last year. Land and sea temperatures were up to 0.2 °C (32.36 °F) higher every single month in the second half of 2023,Continue reading “Climate CERN…”

Topics: Applied Physics, Cosmology, Einstein, History, Physics, Research, Science “To be rather than to seem.” Translated from the Latin Esse Quam Videri, which also happens toContinue reading “Esse Quam Videri…”
When Falsification Has Lease…
Topics: Applied Physics, Civics, Materials Science, Solid-State Physics, Superconductors I’m a person who will get Nature on my home email, my previous graduate school email (that’s active because it’s also on my phone), and my work email. Because it said “physics,” I was primed to read it. What I read made me clasp my handsContinue reading “When Falsification Has Lease…”

Topics: Applied Physics, Atmospheric Science, Existentialism, Futurism, Lasers, Robotics, Science Fiction “Laser” is an acronym for Light Amplification by the Stimulated Emission of Radiation. As the article alludes to, the concept existed before the actual device. We have Charles Hard Townes to thank for his work on the Maser (Microwave Amplification by the Stimulated EmissionContinue reading “Infinite Magazines…”

Graphical abstract. Credit: Joule (2024). DOI: 10.1016/j.joule.2024.01.025 Topics: Applied Physics, Chemistry, Energy, Green Tech, Materials Science, Photovoltaics The energy transition is progressing, and photovoltaics (PV) is playing a key role in this. Enormous capacities are to be added over the next few decades. Experts expect several tens of terawatts by the middle of the century. That’s 10Continue reading “PV Caveats…”

It’s simply an observation based on experience with manufacturing silicon processors and the desire to continually makeContinue reading “Limit Shattered…”
Boltwood Estimate…
Credit: Public Domain Topics: Applied Physics, Education, History, Materials Science, Philosophy, Radiation, Research We take for granted that Earth is very old, almost incomprehensibly so. But for much of human history, estimates of Earth’s age were scattershot at best. In February 1907, a chemist named Bertram Boltwood published a paper in the American Journal of Science detailing a novelContinue reading “Boltwood Estimate…”
