After crisis in interstellar space, stream of Voyager 1 data resumes. Before its computer crashed, the venerable NASA probe may have entered mysterious new region beyond the Solar System.
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.
By weaving popsicle sticks together in a specific pattern, there is a build up potential energy (stored energy) in the bent and twisted sticks. When released from one end, this stored potential energy is converted into kinetic energy (energy of motion) as the sticks rapidly unfurl & fly through the air in a chain reaction. #science#physics#energy#engineering
Albert Einstein's theory of general relativity is tested by Arthur Eddington and Andrew Claude de la Cherois Crommelin.
The Eddington experiment was organised by the astronomers Frank Watson Dyson & Arthur Stanley Eddington in 1919. The observations were of the total solar eclipse of 29 May 1919 and were carried out by two expeditions which aim was to measure the gravitational deflection of starlight passing near the Sun.
In 1919 Andrew Claude de la Cherois Crommelin went to Sobral, in Brazil, and measured the amount of deflection of light caused by the gravitational field of the Sun. The results from these observations were crucial in providing confirmation of the General Theory of Relativity, which Albert Einstein had proposed in 1916.
"We have found a strange foot-print on the shores of the unknown. We have devised profound theories, one after another, to account for its origins. At last, we have succeeded in reconstructing the creature that made the footprint. And lo! It is our own."
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!
Dutch physicist Pieter Zeeman was born #OTD in 1865.
In 1896, while studying the effect of magnetic fields on the light emitted by a sodium flame, Zeeman observed that the spectral lines of the light split into multiple components in the presence of a magnetic field- the Zeeman effect.
In 1902, Pieter Zeeman was awarded the Nobel Prize in Physics, shared with Hendrik Lorentz, for the discovery of the Zeeman effect and its theoretical explanation.

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.
Anyway, the #animation took a bit of thought as it requires a bit of #Mechanics, some #Integration and is made a bit more tricky as the curve is multi-valued and so you need to treat different branches separately. The #AnimatedGif was produce with #WxMaxima.
Entropy balance and time travel in the MCU
(need to know the concept of entropy and homeostasis, and the previous principles of MCU)...
