In the images above, near the summer solstice at 14:00 (UTC+2) in Valencia, the sunlight passing through the center of the circle at the top of the totem marks a point on the analemma. On the right, it is shown at solar noon. Below, the same configuration is shown for February 17.🔭🧪⚛️

My colleague Vicent Peris (@uv.es) and collaborators captured this image on April 5 of the Artemis II spacecraft about 300,000 km from Earth. Its trail appears near Antares and the globular cluster Messier 4. Taken from the AstroCamp Observatory (southern Spain). 🔭🧪⚛️ pixinsight.com/gallery/arte...

At 13:00 (UTC+1), the sunlight that passes through the center of the circle at the top of the totem marks a point on the slab that traces an elongated figure eight over the course of the year: the analemma. The zodiac constellations, days, and months have been marked. This is a solar calendar. 🧪⚛️🔭

Review on The Reinvention of Science by Kyle Cudworth, former director Yerkes Observatory. “One does not need to be a physicist to read and benefit from the book… readers should take time to enjoy the many stories of interesting characters and the fun historical tidbits”🧪⚛️🔭 doi.org/10.56315/PSC...

The Star of Bethlehem. In Giotto’s fresco The Adoration of the Magi, the painter represents the star as a comet. Giotto was able to observe Halley’s Comet in 1301. This comet, with a period of 76 years, was alo observed in the year 12 BCE; therefore, it could not have been the star of Bethlehem🧪⚛️🔭.

Happy solstice! 🌍❄️ Today (Dec 21) at 16:03 (CET or UTC+1) winter officially begins. Shortest day of the year, but your noon shadow will be the longest. From now on, days slowly start getting longer again. Animation by NAAP labs (University of Nebraska-Lincoln) 🧪⚛️🔭#astronomy

OTD (November, the 11th), in 1572, Danish astronomer Tycho Brahe observed a supernova in the constellation of Cassiopeia. In Valencia, shepherds and lime burners were surprised to see the celestial intruder. Page of the book "The Reinvention of Science. Slaying the Dragons of Dogma and Ignorance"🧪⚛️🔭

Leaving Vilnius after a fruitful week of work at the Astronomical Observatory in Moletai and at the University's Physics Department where I gave a talk to a large and interested audience: "What killed the dinosaurs? and other science stories that you were wrongly told”. Many thanks to ACEBaltic🧪🔭⚛️

Next Thursday, September 25, 15:00h, at Vilnius University, Lithuania: “What killed the dinosaurs? And other science stories you were wrongly told”.🧪🔭⚛️🦕🌋☄️

Today, September 22nd, is the autumnal equinox. A good day to try this problem from the book "Fundamental Astronomy" by Karttunen et al. (Springer). Are the sentences underlined in red and in blue correct? Hint: The sequence happens in Havana, let's say on September 22nd. Repost and try it!🧪⚛️🔭

The mathgenealogy.org allows us to reconstruct our academic genealogy: I was a student of B. Jones, who in turn was a student of M. Rees, who in turn was a student of D. Sciama... and so, in 40 steps, we arrive at Nasir al-Din al-Tusi. Many of us are descendants of Persian and Byzantine scholars!🧪⚛️🔭

Princeton paleontologist Gerta Keller's book, "The Last Extinction", is being published tomorrow, September 9th. "The Reinvention of Science" already addressed the debate on the extinction of the dinosaurs: a bolid impact (Alvarez) or extreme volcanism in India (Keller) 🧪⚛️🔭🦕@lissawarren.bsky.social

Yes, you are right. In the Preface of the book we talk🧪 about science and truth: "Our “true” is just the ideas (theories, hypotheses, models and scenarios) that agree most closely with the results of observations and experiments" at a given moment. 🧪⚛️🔭

This is a fantastic new @chanda.bsky.social. I hope to read it soon. Your description is very promising. A poem by Alexander Pope, introduced to me by my co-author Virginia Trimble, led us to write "The Reinvention of Science." By the way, I'm just finishing your first book. #womeninstem 🧪⚛️🔭

Here is the article header with a dialogue made up of two Shakespeare quotes about the stars used as an epigraph.

OTD in 1919 Margaret Burbidge was born. She was the first author of a 1957 article titled "Synthesis of Elements in Stars" that explains the production of elements present in the Earth and the stars. Shakespeare quotes. Photo (1971) from Wikipedia Michael Webb - Hulton Archive. #womeninstem 🧪⚛️🔭

What caused the extinction of the dinosaurs? The bolide impact that created the Chicxulub crater (Alvarez’s hypothesis) or the extreme volcanism that produced the Deccan Traps in India as paleontologist Gerta Keller argues? We talk about this topic in “The Reinvention of Science” #womeninstem 🧪🔭⚛️🦕🌋☄️
