Nossos cumprimentos ao recém empossado Magnífico Reitor da Universidade Federal
de SM
(minha terra natal). O avô mencionado por ele -Vitor Francisco Schuch - foi meu
amigo no início da década de cinquenta, pouco antes de eu deixa a cidade. Tenho também
saudade, e gratas recordações do Chefe Vitor - criador do Clã de Pioneiros Ibitory-Retan 
(nome indígena do local onde se desenvolveu a cidade) - Hoje, um neto meu - Pedro Martin
Achutti Olivé
- tem como Reitor, um neto do Chefe Vitor.
Aproveito para agradecer mais uma vez, na pessoa do neto, as belas aventuras que tive
com seu avô, e ao mesmo tempo enviar meus votos de sucesso.

QUANTUM GRAVITY | ALL TOPICS

 

In a Numerical Coincidence, 
Some See Evidence for String Theory

By NATALIE WOLCHOVER

In a quest to map out a quantum theory of gravity, researchers have used logical rules to calculate how much
Einstein’s theory must change. The result matches string theory perfectly.

Around the Web

No Knowledge, No Problems
Computer scientist Amit Sahai explains “zero-knowledge proofs” — a way to prove something without revealing any additional information — at five levels of difficulty for WIRED. Sahai has used this concept to hide the inner workings
of computer programs from would-be hackers. In a 2014 article for 
Quanta, Erica Klarreich wrote about Sahai’s
pioneering work in “program obfuscation.”


Intentional Icarus
The Parker probe recently entered the sun’s corona, giving us the closest-ever view of our star, Marina Koren
writes for 
The Atlantic. Much about the sun remains a mystery despite its proximity to us. In 2019 Natalie
Wolchover wrote for 
Quanta about scientists’ attempts to understand the gamma rays emanating from our star.
