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
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.
Particle physics and cosmology go hand-in-hand, despite the vast difference in scales. So when something new starts brewing in the quantum world, we pay attention. On this week’s Big Picture Science - could physics experiments take us “Beyond the Standard Model?”
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.
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.
My PhD thesis has been published!
If you're interested in how to manipulate atoms into their coldest possible state using lasers, and why it's interesting to drop them in a 10m vacuum tower, this is for you! Also, fun with "painting" arbitrary shapes with laser beams! #physics#AtomInterferometry#Quantum#QuantumSensing https://doi.org/10.15488/17346
The “Astrophysical and Cosmological Relativity” department at the @mpi_grav in Potsdam announces the opening of several postdoctoral appointments.
These appointments will be in the area of data analysis and its interface with waveform modeling for the recently adopted space-based gravitational-wave detector LISA.
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."
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.
Physicists conjecture that for each cat, there is an anticat of the same size but opposite temperament. Some cats are shifted red and some are shifted blue. I’m not sure I got that all right. I was prety sleepy during the lecture.

Something interesting is rumbling in the physics community. Are we on the brink of discovering a new force of nature? At least one particle physicist thinks so. We venture “Beyond the Standard Model” on Big Picture Science.
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.

Historical note:
1742 Anders Celsius invented the Celsius temperature scale. In its original form the scale had 0 degrees for the boiling point of water and 100 degrees for its freezing point.
1743 The scale was changed by Jean Pierre Christin so that 0 degrees is the freezing point of water and 100 degrees is its boiling point.
Anders Celsius published his research at Abhandlungen über thermometrie, von Fahrenheit, Réaumur, Celsius, (1724, 1730-1733, 1742)
