Mastodawn

A wave of people have left ex-Twitter to check out something called Mastodon.

That leaves many wondering, what is Mastodon anyway?

This explainer by @eff will help you make heads or tails of this new approach to communications and social media.

Leaving Twitter's Walled Garden

This post is part of a series on Mastodon and the fediverse. We also have a post on privacy and security on Mastodon, why the fediverse will be great—if we don't screw it up, and how to make a Mastodon account.

“I wish that, in the future, people will not talk about me because of my achievements in television, but in scientific research, because that would mean that it has an impact.” 😌

Fer Castro: «Oxalá nun futuro se fale de min polo logrado na investigación, non na televisión»

O compostelán, doutor en Estatística, é coñecido en televisión trala súa participación en concursos como «Pasapalabra», «Cifras y letras» e «Saber y ganar». «A este concurso volvín para ter unha sensación de peche, de chegar ás 100 emisións», aclara. Agora, mentres segue investigando na casa, mira opcións para ir a Alemaña

The Digital Independence Day (#DUT #DIday) is an initiative that takes places the first week of each month, to encourage disconnection from digital oligarchs.

Small individual actions won't destroy technofascism, but they're a beginning. And each month you can do one small thing to reduce your presence on the dark side, or to increase it on the bright one!

In 1960, when humans were defined as nature’s only tool-makers, she observed chimp David Greybeard fishing for termites with a twig he had stripped of leaves.

Her mentor: “Now we must redefine ‘tool’, redefine ‘man’, or accept chimpanzees as humans.”

How Jane Goodall changed the way we see animals – and the world

Jane Goodall, who chronicled the social lives of chimps, has died, but she leaves a lasting legacy on how we view the natural world

Goodall worked hard and “saved every penny” to go to Africa with the animals.

“Everybody laughed at me because I was just a girl, we didn’t have any money (and) WWII was raging.”

“Work hard, take advantage of opportunity, but above all, never give up.”

Conservationist Jane Goodall, whose work revolutionized the study of primates, has died

Jane Goodall, whose lifelong work as a primatologist helped broaden the world’s understanding of animal behavior and emotions, has died, her institute said Wednesday. She was 91.

There has been a remarkable breakthrough towards the Riemann hypothesis (though still very far from fully resolving this conjecture) by Guth and Maynard making the first substantial improvement to a classical 1940 bound of Ingham regarding the zeroes of the Riemann zeta function (and more generally, controlling the large values of various Dirichlet series): https://arxiv.org/abs/2405.20552

Let 𝑁(σ,𝑇) denote the number of zeroes of the Riemann zeta function with real part at least σ and imaginary part at most 𝑇 in magnitude. The Riemann hypothesis tells us that 𝑁(σ,𝑇) vanishes for any σ>1/2. We of course can't prove this unconditionally. But as the next best thing, we can prove zero density estimates, which are non-trivial upper bounds on 𝑁(σ,𝑇). It turns out that the value σ=3/4 is a key value. In 1940, Ingham obtained the bound $N(3/4,T) \ll T^{3/5+o(1)}$. Over the next eighty years, the only improvement to this bound has been small refinements to the 𝑜(1) error. This has limited us from doing many things in analytic number theory: for instance, to get a good prime number theorem in almost all short intervals of the form $(x,x+x^\theta)$, we have long been limited to the range $\theta>1/6$, with the main obstacle being the lack of improvement to the Ingham bound. (1/3)

New large value estimates for Dirichlet polynomials

We prove new bounds for how often Dirichlet polynomials can take large values. This gives improved estimates for a Dirichlet polynomial of length $N$ taking values of size close to $N^{3/4}$, which is the critical situation for several estimates in analytic number theory connected to prime numbers and the Riemann zeta function. As a consequence, we deduce a zero density estimate $N(σ,T)\le T^{30(1-σ)/13+o(1)}$ and asymptotics for primes in short intervals of length $x^{17/30+o(1)}$.

From zero to hero: The story of #KatalinKariko , who just won the #NobelPrize and epitomises the success of underdogs in science. 👩‍🔬

“There was even a study done in the Harvard Business Review that tried to find out why I never got money in the past.
[...]
The issue is that all the money and prestige are very centralized in the world of science. If you are not close to that centre, you have no money, no fame and no prestige.”

Katalin Karikó: «Women should have a career and a happy family»

Scientist Katalin Karikó’s work didn’t get the attention it deserved until the start of the pandemic in 2020, when suddenly her area of expertise, mRNA, became the most important subject of research worldwide. From one day to the next, Karikó became the star of the scientific community. Today she looks back on why her research was not funded, advocates for new role models and explains why she didn`t give up her career for her family.

Hello, world! I am joining Mastodon in an effort to help the #TwitterDiaspora movement get stronger. 💪

I will be publishing here more and better content than on https://twitter.com/FerCPr , with the idea of using Musk's product less and less. 😇

I also hope to encourage others to follow the same steps. 🐾🐾
