Amazing how tiny the pieces are. The photo was taken with an electron microscope. More about MEMS accelerometers here: https://mems.polimi.it/index.php/accelerometers?fbclid=IwAR2riO6QcedkMZXuZJCsXvM2evY9m_Dv8fbpsf7GwjQdw8dL_NyYaVugmYo
2023-06-24 Why Is Water So Remarkable? Tyson
Neil deGrasse Tyson explains why the remarkable change in water at 4 degrees C is why we are alive today. When water gets colder it gets denser, until it reaches 4 degrees C, then it gets less dense as it gets colder until it freezes at 0 degrees C. This causes the ice to float

2021-08-09 Breakthrough In Battery Technology
He talks about developing batteries taking a long time – years – because it’s like cooking: you put things together and then taste it, to see how it works. They have automated some of the procedures, but it’s still time consuming to do all the lab work to find the right chemistry. That is apparently

2021-07-03 The Myths Of August — Fusion
p.259 << FUSION For over three decades, the goal of fusion research has been to build a machine to harness the violent process that powers the stars and ignites hydrogen bombs. The daunting challenge confronting scientists and engineers working on this project has been to design a reactor that would provide inexhaustible energy by enabling
