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.

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.

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.

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.

The Scar: A Tender Illustrated French Meditation
on Loss and Healing

I know only three side-doors to the cathedral of consciousness, through which
we can bypass the bewildered mind to enter the heart of the most unfathomable,
shattering, and universal human experiences, emerging a little more whole:
poetry, children’s books, and Bach.

No human experience is more shattering than the vanishing of a loved one
into “the drift called ‘the Infinite,'” in Emily Dickinson’s haunting phrase
 — especially a parent, and especially if one is still a child when the unfeeling
hand of chance smites./.../

June Lindsey, seen at the age of 96, played a key role in the discovery of the DNA double helix, but she was never formally recognized for her work. Lindsey died in Ottawa earlier this month at the age of 99.

June Lindsey, a forgotten pioneer of DNA

In the story of the discovery of DNA, alongside Rosalind Franklin,
there was another X-ray crystallographer whose contribution has
been widely neglected: June Lindsey
. Born June Broomhead, she
discovered the structure of adenine and guanine — a key part of
solving the DNA double-helix puzzle. In 1945, Lindsey joined the
legendary Cavendish Laboratory at the University of Cambridge,
UK. “I think she had the best time of her life,” says her daughter
Jane. That’s where DNA co-discoverer James Watson consulted
Lindsey’s thesis, which sparked a new understanding of the
makeup of the molecule of life.

Lindsey is the latest woman to be featured in Chemistry World’s
‘Significant Figures’ series, thanks to Briefing reader Alex MacKenzie. He wrote to us after we featured the edition about chemist Julia Lermontova, and I passed his
comments on to Chemistry World. Lindsey died in November, at
the age of 99, but in March MacKenzie wrote that Lindsey was
“still with us, living in a retirement home in Ottawa, lucid and clear
eyed, she remains a delight”. As he said in a previous interview,
“I would love, ultimately, for her to be known.”

Rebalancing Ocean Carbon
Removing carbon dioxide from our atmosphere is critical to fighting climate change. Equally important is its removal from our oceans, as Scott K. Johnson reports for Ars Technica
One key to removing CO2 from the ocean is fighting ocean acidification. In 2019, Christie
Wilcox wrote for Quanta about how dead creatures on the sea floor can help maintain a
healthy pH.

Be Chill but Don't Freeze
Researchers managed to keep water in its liquid form down to -47.2 degrees Fahrenheit, Ashley Hamer reports for Live Science. Water’s phase diagram is vastly more complicated than textbooks usually describe. Not only can it be a frigid liquid, but it can also be a sweltering solid. In 2019, Joshua Sokol wrote for Quanta about “superionic ice,” water ice with a temperature of thousands of degrees.
