Sunday, February 13, 2022

Dear Nautilus Reader,

 

Is time real? When theoretical physicist Subodh Patil was a boy, his father teased him that the world was only 100 years old. Since then, Patil has been fascinated with time and determined to understand its origins—if, that is, it has origins.

 

That story, a look at a tricky math problem involving the area of a circle and square; a lively discussion between two acclaimed neuroscientists on consciousness, panpsychism, and the self; and more, in some of the most popular stories on Nautilus this week.

Female scientists: don’t wait to be perfect

“I have worked in some of the most male-dominated sectors you can work in,” says Pontsho Maruping, who started her career in mining and is now a deputy managing director at the South African Radio Astronomy Observatory. She offers detailed advice for up-and-coming women in African science and engineering. “When offered a chance to lead a new project, I tell young professionals to say ‘yes’,” she writes. “Women tend to want to be perfect first, but it’s the times when I’ve said yes to challenges that have provided the biggest opportunities to grow career-wise.”

Mysteries of Stephen Hawking's doodle-filled blackboard may finally be solved

(Isidora Bojovic/Science Museum Group)

A new museum exhibit hopes to uncover the secrets behind the doodles, in-jokes and coded messages on a blackboard that legendary physicist Stephen Hawking kept untouched for more than 35 years.

The blackboard dates from 1980, when Hawking joined fellow physicists at a conference on superspace and supergravity at the University of Cambridge in the U.K., according to The Guardian. While attempting to come up with a cosmological "theory of everything" — a set of equations that would combine the rules of general relativity and quantum mechanics — Hawking's colleagues used the blackboard as a welcome distraction, filling it with a mishmash of half-finished equations, perplexing puns and inscrutable doodles.

People who had N-terminal pro-brain natriuretic peptide (NT-proBNP) levels checked at year 1 in the old SEAS study had varying rates of aortic valve events (AVEs) -- a composite of aortic valve replacement, cardiovascular death, or incident heart failure due to AS progression -- over the next 2 years depending on AS severity and adjusted NT-proBNP: Mild AS and normal NT-proBNP: 1.39 per 100 patient-years Mild AS and increased NT-proBNP: 7.05 per 100 patient-years Moderate AS and normal NT-proBNP: 10.38 per 100 patient-years Moderate AS and increased NT-proBNP: 26.20 per 100 patient-years/.../ # MACHINE LEARNING | ALL TOPICS   Machine Learning Becomes a Mathematical Collaborator By KELSEY HOUSTON-EDWARDS Two recent collaborations between mathematicians and DeepMind demonstrate the potential of machine learning to help researchers generate new mathematical conjectures.

The KATRIN experiment is trying to do just that, Marcus Woo wrote for Quanta in 2019. Putting the Art in Artificial Intelligence Researchers are using AI for creative tasks like painting and composing original music, reports Richard Moss for Science News. Some think that injecting creativity into AI algorithms will be the key steppingstone to building truly intelligent machines. For an algorithm’s solutions to be creative and open-ended, the problems must be open-ended, too. Matthew Hutson wrote about it for Quanta in 2019.
