Galileo’s handwritten notes found in ancient astronomy text Discovery sheds new light on how famed astronomer came to lead a scientific revolution

Years before Galileo made his observations of the 🌙 and Jupiter's moons, he intensively studied the work of Claudius Ptolemy, until Ptolemy's own mathematical logic brought Galileo to "the moment when Earth was thrust from the center of the Universe". A fascinating discovery if confirmed. 🔭 🧪 🎢

The Physics of A.I. YouTube video by ScienceClic English

Good and entertained video listing the connections between #Physics and #AI . Seems that multi-layer artificial neural networks are not only a mathematical tool but they resemble a description of nature's deep behavior. #science 🧪 🎢 #math

Is there a formal name to describe the phycological and physical burden that carries the process of answer to reviewers? 😩 #AcademicSky

The 5 stages of the ‘enshittification’ of academic publishing Academic publishing now shows the same decline that has hit social media and online marketplaces.

The "enshittification" driven by the toxic academic culture of "publish or perish". With publishers getting ↗️ profits -alike the music & movie industry- at the expense of degradation in scholars integrity ↘️: clear trend! Why are we doing this damage to #science? How to revert it? 🧪⚛️🎢 #AcademicSky

Imagine starting new year seeing your paper published on January 1st where a long thought plasma stability limit has been overcome, a breakthrough in nuclear fusion, one of the most important scientific project for the future of humanity. What a success! 🧪⚛️🎢 #physic

Great science happens in great teams — research assessments must try to capture that Europe must reform the ways in which science is evaluated. To boost innovation, it must improve research culture.

"Great science happens in great teams". True! but evaluation & recognition still done individually. Papers written equally by all authors are rare, only leader author takes a big chunk of the work. Whatever ideas this committee will come out shouldn't be more work load for scientists. 🧪 #AcademicSky

Whatever "High/Low emission" means here, & putting aside far-fetched conclusions about how our lives will be affected... the plot shows that only one High emission scenario slows down the #AMOC collapse by 100yrs. Shall we aim to reach that scenario? Since it will collapse anyhow 🧪❄️🥼🌊

The sci-fi films that physicists love to watch — from Interstellar to Spider-Man Nature surveyed scientists about their favourite cinematic moments to celebrate the International Year of Quantum Science and Technology.

Although I agree with the top 2 of this list, I find it a crime that the film "Contact" based on Carl Sagan's book wasn't event mentioned. And what about "Arrival"?? A bit disappointed of fellow physicists 😛 #AcademicSky 🧪 🥼❄️ 🔭 🎢 ⚛️

UK scientist's remains found on Antarctic glacier 66 years later DNA testing confirms human remains recovered from an Antarctic glacier are those of a British meteorologist who fell down a crevasse during an expedition in 1959.

The glacier retreat allowed to find his rests lost in 1959; this's the story of @bas.ac.uk #Meteorologist Dennis "Tink" Bell. Ironically global warming is helping to acknowledge those who gave their lives to Polar exploration whose early research allows us a better understanding of the #Climate 🧪❄️🎢

Just how bad will climate change get? The only way to know is to fund basic research Predictions of global warming are uncertain. That’s why we need to keep finding out how the climate system works.

Science needs to stay objective & factual, this @nature.com article #TimPalmer presents a compelling argument on why basic climate research is paramount. Avoid extremes of misleading arguments by political parties/ immoderate conclusion by @wwattribution.bsky.social like people is detrimental. 🧪 ❄️🎢🥼

The peer-review crisis: how to fix an overloaded system Journals and funders are trying to boost the speed and effectiveness of review processes that are under strain.

Good that the issues with peer-review (PR) are trying to be tackled. However, schemes like distributed PR or journals requiring authors to take care of PR process before submitting are just passing the hurdle to authors while journals' APC contine to increase! How to understand that? #AcademicSky 🧪

Portrait of Wheeler in his twenties. He is wearing a dark jacket, white shirt, and tie. Wheeler is looking to the side of the camera.

An older wheeler standing in front of a chalkboard. His hands are clasped. The diagram behind him shows a direct path from point A to point B labeled “classical,” and a wave emanating from A and passing to B labeled “quantum.”

Wheeler walking with Einstein, Tomonaga, and a fourth person, through the woods near the Institute for Advanced Study.

Physicist John Archibald Wheeler was born #OTD in 1911.

A titan of 20th century science, he introduced the S-Matrix; developed (with Bohr) the first general theory of fission; coined "worm hole" and popularized “black hole”; and trained Feynman, Everett, Thorne, and many others. 🧪 ⚛️

Is a monster web of ocean currents headed for collapse? The race is on to find out Research ships rarely brave the Greenland Sea in winter. Early this year, scientists ventured into the ice-covered waters to capture crucial data about the planet’s future.

Unlike many press coverage only focusing in fine tuning modeling results to support #AMOC collapse, this @nature.com article highlights scientist different hypothesis & theories on what could happen with the #AMOC in the future climate. Main point, we need observations, #science is lead by data. 🧪❄️🌊

Happy birthday quantum mechanics! I got a ticket to the ultimate physics party Nature reporter joins hundreds of physicists on a remote island to celebrate Heisenberg’s enlightening trip there 100 years ago.

Most of the hard work is done in the lab, but the inspiration, ideas for research and breakthroughs come from unexpected places and moments. That's why scientific in-person conferences are still places where great #science is forged. <happy|birthday> #quantum #mechanics #iTeachMath #iTeachPhysics

How do I choose a principal investigator for my next postdoc? A computer scientist is struggling to trust their postdoctoral research adviser after negative experiences with the previous two. How do you find one that’s right for you?

This @nature.com article delusional hints (ok for Computer Science?): "Identity what you want, interview several potential PIs, get support from other postdocs..."
The reality in physical sciences: Send 100+ job applications, one might work out, that's the right PI for you, period. #AcademicSky 🧪 ❄️

Scientific conferences are leaving the US amid border fears Some meetings have been put on hold in response to foreign researchers’ travel concerns.

If #conference attendees are denied entrance at country's border control... will conference organizations #refund the registration/abstract fees? If they cannot ensure refund, they should move the venue out to another country. What's your policy @agu.org ?? 🧪 #academicsky #AGU2025 #NewOrleands

Which programming language should I use? A guide for early-career researchers Computer scientists and bioinformaticians address four key questions to help rookie coders to make the right choice.

Not true! In fact new Data shows no significant signal towards an #AMOC switch-off👇🏽🌊❄️
