Frank Drake stands in front of a whiteboard with his eponymous equation, which estimates the number of detectable alien civilizations in the Milky Way galaxy.

COURTESY OF SETI INSITUTEWhy alien hunters have spent 60 years finding new solutions for the Drake Equation 
Astronomer Frank Drake came up with the famous formula as he prepared for a last-minute meeting in 1961. It still guides the search for intelligent life beyond Earth.

“Dad, did you ever imagine that your formula would become so famous?” I ask the kind-eyed, 91-year-old person next to me on the patio.
My dad, Frank Drake, is quiet for a moment. Perhaps he’s thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind’s hunt for extraterrestrial civilizations. Or maybe he’s listening to the shrieking scrub jays and chattering woodpeckers in the yard, confirmation that noisy lifeforms are thriving in at least one part of the cosmos./.../#The NY Review of Books

Knot theorists proved the validity of a mathematical formula about knots after using machine learning to guess what the formula should be. (DeepMind)

DeepMind’s AI untangles knots Artificial-intelligence (AI) powerhouse DeepMind has teamed up with mathematicians to spot previously unseen patterns and seek new discoveries. Researchers trained a machine-learning algorithm on vast amounts of data about knots and revealed a formula linking two properties of knots — which the mathematicians then proved rigorously. In a separate test, the team found a potential pattern related to symmetries, which had been sought for decades. “I was very struck at just how useful the machine-learning tools could be as a guide for intuition,” says knot theorist Marc Lackenby.

Darwin’s theory of evolution was the first to be proposed, and it was a direct challenge to the Christian idea that the planet was created in six days. His assertions were based on the findings he had made during his five-year voyage abroad aboard his ship, the Beagle./.../ #Britannica 1967: Christiaan Barnard of South Africa performed the first human heart transplant, at Groote Schuur Hospital in CapeTown. [Test your knowledge of famous doctors.] Era um domingo quando ouvimos a notícia no carro, dirigindo em direção a Novo Hamburgo, onde provavelmemte iríamos almoçar.

By NATALIE WOLCHOVER The James Webb Space Telescope, a $10 billion project decades in the making, has been designed to find answers to the core questions that have animated astronomers over the past half century. It is one of the most ambitious engineering projects ever attempted. But for it to achieve its potential — nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it — a lot of things have to work just right.

A dark-horse quantum simulator has now done just that. Read the blog   QUANTIZED COLUMNS   Will We Ever Get Rid of COVID-19? By TARA C.

As Ewen Callaway reports for Nature, scientists are racing to understand what those mutations imply about the variant virus’s transmissibility and the severity of its infections, as well as about the efficacy of vaccines. Thankfully, work is progressing rapidly, in part because of South Africa’s large genome monitoring effort. In June, Puja Changoiwala reported for Quanta about the necessity of genomic surveillance for curbing the pandemic. The New Neutrino Factory In a first, the Forward Search (FASER) experiment at the LHC has detected signs of neutrinos produced by a particle collider, Chelsea Gohd reports for Space.com. The new ability to detect and study neutrinos produced by the LHC may help scientists finally understand these strange subatomic particles. In October, Thomas Lewton wrote for Quanta about the confounding neutrino mysteries yet to be solved. #Mona Lisa # Advento - Primeira semana Valderês costumava comemorar o Advento.

#Boneco de Murano

Tem história: tenho que pesquisar o ano, mas pode ter sido ainda no início da década de setenta. Valderês o viu em exposição na Casa Masson e perguntou o preço. Disseram-lhe que já estava vendido. Ela ficou triste e me contou. Poucos dias depois, lembro que eu estava na Enfermaria 38o. da Santa Casa, e ela veio muito contente me contar que haviam telefonado para ela, dizendo que quem comprara o boneco veio devolver porque familiares não tinham gostado da cara dele. Compramos em prestação, e até hpje o conservamos como símbolo de que uma frustração nem sempre é definitiva....

#22/novembro/1963

Lembro que neste dia eu estava trabalhando, pela manhã, na Secretaria de Educação, num Edifício que ficava numa travessa próxima ao Cais da Av. Mauá. Com a notícia, Valderês foi me busscar de carro, com uma de nossas filhas. Estávamos chocados como conciliar com a violência, o que de bom conhecemos de nossa espécie, e em particular dos americanos

Listen to the podcast Read the article Around the Web Fast Radio Bursts Get Fresh Answers An explanation for the intense pulses of radiation called fast radio bursts (FRBs) has eluded astronomers until now. Recent observations and in-depth studies have started fitting the puzzle pieces together, Adam Mann reports for Scientific American. One of the FRB puzzle pieces is the role of magnetars, highly magnetized neutron stars. In 2019 Josh Sokol reported for Quanta on a new model explaining how FRBs occur when magnetars make shockwaves by hurling charged particles outward. Pregnancy, Placentas and Autoimmune Disease  Why do 80% of autoimmune disease cases afflict women? During pregnancy, the placenta helps to lower immune defenses. A new theory suggests that lower pregnancy rates are leaving women’s immune system hypervigilant, Olga Khazan reports for The Atlantic. The placenta’s ability to foil immunological defenses resembles that of cancer cells. Earlier this year Max Kozlov reported for Quanta about scientists who are studying the placenta to better understand and beat cancer. #BING Imagem do Telescópio Espacial Hubble do aglomerado de galáxias MACS J0416 Os aglomerados de galáxias não são compostos por apenas algumas galáxias, nem mesmo por uma dúzia delas. Em um aglomerado, normalmente existem de centenas a milhares de galáxias unidas pela gravidade. Estamos olhando para um desses aglomerados nesta imagem capturada pelo Telescópio Espacial Hubble. Conhecido como MACS J0416, esse aglomerado tem muita massa: 160 trilhões de vezes a massa do nosso Sol. Mas essa não é a única informação extraordinária sobre o objeto celestial: ele também tem a capacidade de agir como uma espécie de lente e, portanto, amplia galáxias que estão muito mais distantes. Essa propriedade é chamada de lente gravitacional e foi prevista pela teoria geral da relatividade de Albert Einstein. Quer outra informação impressionante? Em 2017, cientistas lançaram o mapa mais detalhado de matéria escura no universo já compilado, e o estudo deles do MACS J0416 ajudou nessa grande descoberta. Aprenda sobre nosso sistema solar #Dra.
