1928-1929: Instabilities in plasmas result in oscillations of electron charge density. #Poetry #Science #History #Physics #Plasmas #Langmuir #Tonks (https://sharpgiving.com/thebookofscience/items/p1928c.html)

Notes on #UAP Discussions : How would you introduce a class on "theoretical advances in novel propulsion systems " ?
if you were going to start with early history your candidates are primarily #Antigravity and #Electrostatics but a basic functional approach might start with concepts of mass levitation and associated phenomenologies like #Superconductivity, #Magnetohydrodynamics, #plasmas and #Solitons. Emphasis should be on the fact that there is more than one path to unconventional propulsion

#Physicists often turn to the Rayleigh-Taylor instability to explain why #fluid structures form in #plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around #supernova 1987A, research from the University of Michigan suggests.

#Nature 📆 10 November 2022 #Electric #propulsion : The gaseous #propellant is priorly #ionized and the charged #particles in the #plasmas are energized and #accelerated by applying #electromagnetic fields. #Electric #power obtained by #solar panels is converted into the #kinetic #energy of the propellant. A 30% conversion #efficiency is the highest to date https://www.nature.com/articles/s41598-022-22789-7

Most people are familiar with #solids, #liquids, and #gases as three states of matter. However, a fourth state of matter, called #plasmas, is the most abundant form of matter in the #universe, found throughout our #solar system in the #sun and other #planetary bodies
