No comando...

Natal 2021

Este é o primeiro Natal sem a presença Dela (Valderês, minha querida esposa), e o terceiro sem a cunhada dela (minha irmã Lia Maria) É provável que lembrem das festas que ela gostava de organizar aqui em casa, não somente no Natal. Arrumava tudo, com decoração apropriada. No Natal com pinheiro enfeitado, presépio e luzinhas. A gente ajudava, e alguns de vocês também devem ter participado.

Ceia de Natal, durante muitos anos servida com Peru. Houve anos que ganhamos perús já preparados, e ao menos um ano vieram perús a pé…Houve época em que o peru era levado para locais especializados na preparação. Não havia peru congelado. Lembro de um ano em que sobrou, e levamos um já preparado, e entregamos no Asilo Padre Cacique.

Experimentamos de tudo, amigo secreto, música,  distribuição de presentes…

Mas o que eu gostaria de lembrar era o discurso que ela costumava fazer, prendendo a atenção de todos durante alguns momentos. Achei uma fotografia em que ela está, em pose característica, frente a lareira, na sala com minha irmã ao lado. Pena que não a tenha filmado.. As palavras eram de paz, saúde, amor  e harmonia.

Presentes, já não tenho mais muitas condições de distribuir, mas a herança que já foi repartida, e o que ainda virá, é presente dela, e fruto dos setenta anos de convívio que tivemos.

Confesso que me sinto frustrado em não dar continuidade à cerimônia de distribuição de presentes, mas precisamos assumir que os tempos são outros, e que não vamos conseguir compensar a falta que ela faz.

Podemos sim, manter nossos laços afetivos, e as boas lembranças dos anos que passou conosco.

Meu abraço a cada um, com votos de saúde, felicidade e sucesso.

Minha irmã Maria Helena, dando-me o prazer de sua companhia, se associa à nossa celebração.

Aos parentes, à Celita e aos amigos presentes em nossas vidas, também nosso agradecimento e votos de Feliz Natal.

Muito obrigado por vocês existirem e, de alguma forma darem continuidade à existência e à memória da minha querida Valderês Antonietta

SPACE EXPLORATION How to watch the James Webb telescope launch into space (NASA GSFC/CIL/Adriana Manrique Gutierrez) On Friday (Dec. 24) at 7:20 a.m. EST, a shiny new observatory called the James Webb Space Telescope (JWST) is scheduled to ride a rocket launching from South America. Once aloft, the space telescope will take its place in orbit as humanity's newest and most powerful eye in the sky, scanning the cosmos for signs of the earliest galaxies, newborn and ancient stars, and even life in distant solar systems. Live launch coverage in English begins on Dec. 24 at 6 a.m. EST. You can watch the launch here at Live Science, on NASA's YouTube channel and NASA TV, and on the agency's website and social media accounts. Spanish language coverage will begin at 6:30 a.m. EST on the NASA en español's YouTube account and on NASA's website, NASA representatives said on Saturday (Dec. 18) in a statement. You can also check in at our sister site Space.com all week, to catch the latest updates leading up to the Dec. 24 launch.  Full Story: Live Science (12/21)

MATH & PHYSICS Imaginary numbers could be needed to describe reality, new studies find (Jurik Peter via Shutterstock) Imaginary numbers are necessary to accurately describe reality, two new studies have suggested. Imaginary numbers are what you get when you take the square root of a negative number, and they have long been used in the most important equations of quantum mechanics, the branch of physics that describes the world of the very small. When you add imaginary numbers and real numbers, the two form complex numbers, which enable physicists to write out quantum equations in simple terms. But whether quantum theory needs these mathematical chimeras or just uses them as convenient shortcuts has long been controversial.  Full Story: Live Science (12/21)      Frozen tardigrade becomes first 'quantum entangled' animal in history, researchers claim (STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY/Getty Images) Tardigrades — those microscopic, plump-bodied critters lovingly known as "moss piglets" — have been put through the ringer for science. The amazingly durable creatures have been shot out of guns, bathed in boiling-hot water, exposed to intense ultraviolet radiation and even (accidentally) crash-landed on the moon, all to test the limits of their impressive "tun" state — a survival mechanism wherein tardigrades curl up into shrunken, dehydrated balls and suspend their biological functions indefinitely in order to endure extreme environmental conditions. Now, researchers have exposed tardigrades to the coldest temperatures and highest pressures that moss piglets have ever survived — not just to test the critters' biological limits, but also to see whether a frozen tardigrade could be incorporated into two quantum entangled electric circuits, then later revived to its normal active state.  Full Story: Live Science (12/20)  #   COMPUTER SCIENCE, MATHEMATICS The Year in Math and Computer Science By BILL ANDREWS Mathematicians and computer scientists answered major questions in topology, set theory and even physics, even as computers continued to grow more capable.

Impeccably preserved dinosaur embryo looks as if it 'died yesterday' (Shoulin Animation) About 70 million years ago, a wee ostrich-like dinosaur wriggled inside its egg, putting itself into the best position to hatch. But that moment never came; the embryo, dubbed "Baby Yingliang," died and remained in its egg for tens of millions of years, until researchers found its fossilized remains in China. Researchers have discovered many ancient dinosaur eggs and nests over the past century, but Baby Yingliang is one of a kind. "This skeleton is not only complete from the tip of the snout to the end of its tail; it is curled in a life pose within its egg as if the animal died just yesterday," said study co-researcher Darla Zelenitsky, an assistant professor of paleontology at the University of Calgary in Alberta, Canada.   Full Story: Live Science (12/21)
