@talia_christine@mynameistillian Physics isn't just quantum physics, you know. I study material science and I could lick samples with relative impunity (aside from everyone else in the lab looking at me like I lost my marbles).
Pioneering geologist & oceanographer Marie Tharp changed our understanding of the ocean.
When Tharp sought a geology job at Columbia in 1948, women couldn’t go on research ships. So she was hired to assist male grad students.
Back then, many scientists still assumed the bottom of the ocean was featureless. Tharp figured out how to use data to create sketches of the ocean floor. Her hand-drawn maps helped develop plate tectonic theory. https://www.ncei.noaa.gov/news/marie-tharp#science#history
Astronomers using JWST have just identified the earliest, most distant galaxy known. This image shows JADES-GS-z14-0 as it was when the universe was 2.2% its current age.
It's quite possible that JADES-GS-z14-0 evolved into a galaxy much like our own. Or that someone in that galaxy, looking back at us, would see something similar to JADES-GS-z14-0.
Guglielmo Marconi applies for a patent for his wireless telegraph.
On 13 May 1897, Marconi sent the first ever wireless communication over open sea – a message was transmitted over the Bristol Channel from Flat Holm Island to Lavernock Point near Cardiff, a distance of 6 kilometres. The message read "Are you ready".
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."
More than 46 years after launch, more than 15 billion miles from home, NASA's Voyager 1 spacecraft is restored, rebooted, and once again sending data back to Earth.
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
A beluga can change the shape of its "melon" (the bulbous mass on its head) at will. Could this be used as a form of communication? A new study indicates that it might. Here's a story from @hakaimagazine with a six-panel comic illustrating the five different melon shapes and in what contexts some are used.
Ed Dwight became America’s first Black astronaut candidate some 60 years ago. He wasn’t picked for the 1963 class and that he would never experience the weightlessness of outer space. That changed on Sunday as Dwight, now 90, rocketed into space with Blue Origin, becoming the oldest person to take a space flight. The previous recordholder? William Shatner.

There’s a gravity hole — a spot where the Earth’s gravitational pull is weaker — in the Indian Ocean, causing the sea level to dip by over 328 feet (100 meters). The anomaly has puzzled geologists for a long time, but researchers think they’ve found a credible explanation: magma.

Seven candidate Dyson spheres found from their excess infrared radiation could be a case of mistaken identity, with evidence for dusty background galaxies spotted close to three of them.
“They could be an astrophysical phenomenon such as extreme debris discs, or something more exotic,” says Ann Marie Cody, an astronomer at the SETI Institute in California who is not involved in Project Hephaistos, but has conducted her own Dyson swarm search.
A 23-year study found that barley grown under organic farming conditions developed unique genetic adaptations, enhancing resilience to nutrient and water deficiencies.
Unlike conventionally farmed barley, which became genetically uniform, organic barley maintained genetic diversity, aiding adaptation to environmental changes.
ATTERRISSAGE REUSSI 🎉
Cette nuit, la sonde Chang'e 6 🇨🇳 s'est posée dans le cratère Apollo sur la face cachée de la Lune 🌒
Il transporte l'instrument DORN 🇫🇷 qui va mesurer le taux de radon.
Tellement heureux pour mes amis toulousains qui l'ont conçu et l'opèrent !
My partner pointed out that I have a case of schrodinger’s good/bad dog. I have an English Cocker Spaniel named Miles. He loves walks in the forest. Loves chasing things (rabbits, birds) off into the undergrowth and also loves rolling in dead birds.
Now if he rolls in a dead bird while in the undergrowth and I don't see him is he a good dog or a bad dog? We don't know unless I go into the undergrowth to find out.
On the lunar surface, a single Earth day would be 56 microseconds shorter — a tiny number that can lead to significant inconsistencies over time. That’s why scientists aren’t just looking to create a new “time zone” for the Moon, but an entirely new “time scale” that accounts for the faster speed at which seconds tick by up there.
