This is quite interesting. (no... really!) I recently persuaded a colleague to take my pet Geiger counter from Dunedin to Apia via Auckland. The latitude dependency of the radiation exposure is fascinating! #radiation#NewZealand#physics
French physicist Jean-Pierre Christin published the design of a mercury thermometer using the centigrade scale with 0 representing the melting point of water and 100 its boiling point.

English self-taught mathematician and physicist Oliver Heaviside was born #OTD in 1850.
He invented a new technique for solving differential equations, independently developed vector calculus, and rewrote Maxwell's equations in the form commonly used today. He significantly shaped the way Maxwell's equations are understood and applied in the decades following Maxwell's death. His practical experience in telegraphy provided a foundation for his later theoretical work.
British physicist Peter Higgs was born #OTD in 1929.
In 1964, Higgs proposed a theory explaining how particles acquire mass. This mechanism involves the interaction of particles with a field, now known as the Higgs field. The field has an associated particle (Higgs boson). The search for the Higgs boson became a major focus of particle physics experiments. In 2012, scientists at CERN's Large Hadron Collider announced the discovery of a new particle consistent with the Higgs boson.
A couple of weeks ago, I posted an #animation of a point on a circle generating a #cycloid.
If you turn the curve "upside down", you get the #BrachistochroneCurve. This curve provides the shortest travel time starting from one cusp to any other point on the curve for a ball rolling under uniform #gravity. It is always faster than the straight-line travel time.
Awhile back I had some odd physics ideas but was having trouble finding user-friendly tools to try them out.
Somewhere along the way I stumbled across Principia, & while the base version wasn't capable of what I wanted to try, I appreciated it regardless for being a cool, user friendly physics toy.
Sometime maybe I'll try modifying it to try out my odd ideas. Give it a look if you're into digital toys!
Think I might have caught a cosmic ray air shower at work today. Running a Geiger counter which normally gives about 20 counts a minute for background here, but got a sudden burst of at least 20 counts in about 5 seconds. Other than that the rate was roughly normal. No strong sources nearby, no high voltage systems, did several minutes of counts either side of it which were completely normal. What do you reckon? #Physics#Astrophysics
After atoms, it's now the turn of molecules to form a Bose–Einstein condensate.
"Physicists have succeeded in cooling down molecules so much that hundreds of them lock in step, making a single gigantic quantum state. These systems could be used to explore exotic physics, such as by creating solid materials that can flow without resistance, or could form the basis of a new kind of quantum computer."
Entropy balance and time travel in the MCU
(need to know the concept of entropy and homeostasis, and the previous principles of MCU)...
