“Pure mathematics is, in its way, the poetry of logical ideas”*…
Alexander Grothendieck is revered in the world of math; outside of it, he’s known for his unusual life, if he’s known at all. Konstantin Kakaes outlines his actual mathematical contributions…
What Albert Einstein was to 20th-century physics, Alexander Grothendieck was to 20th-century mathematics. He is much less well known because math gets technical even more quickly than physics does. But as with Einstein, Grothendieck’s impact came not just from his own results, revolutionary though they were. His work also reoriented his entire discipline in radical new directions.
Grothendieck was intense and ascetic from his early days. Starting in the early 1950s, when he was in his 20s, he produced thousands of pages of formal and informal notes that changed the course of mathematics. Then in 1970, he quit. He left his post at a prestigious research institute just outside of Paris to teach at the provincial university in Montpellier where he studied as an undergraduate. He mostly stopped talking to other mathematicians. In the early 1990s, he moved to a small village in the Pyrenees, where he lived as a hermit.
Mathematicians are still grappling with the innovations he made half a century ago. His work pushed mathematics to a new level of abstraction by focusing on the relationships between objects rather than the objects themselves. “If there is one thing in mathematics which fascinates me more than any other (and undoubtedly always has), it is neither ‘number’ nor ‘size,’ but invariably shape,” he wrote in his memoirs. “And among the thousand and one faces under which shape chooses to reveal itself to us, that which has fascinated me more than any other and continues to do so is the structure hidden in mathematical things.”
His revolutionary mathematics centered around that search for hidden structure…

As we study shape, we might send speculative birthday greetings to a man who, while not technically a mathematician, nonetheless created a famous equation: Frank Drake; he was born this date in 1930. An astronomer and astrophysicist, he formulated the Drake Equation in 1961 to estimate the number of technological civilizations that might exist in the Milky Way galaxy, N = R* × fp × ne× fl × fi × fc × L. Using plausible guesses for the parameters, Drake concluded perhaps 10 planets in our galaxy may have life originating detectable signals. In 1960, Drake led the first search, the two-month Project Ozma to listen for patterns in radio waves with a complex, ordered pattern that might be assumed to represent messages from some extraterrestrial intelligence.
Carl Sagan and Drake designed the plaques on Pioneer 10 and Pioneer 11 for the purpose of greeting and informing any extraterrestrial life that might find the vessels after they left the solar system.

Bijgewerkte formule over buitenaardse intelligentie suggereert dat we echt alleen zijn in de Melkweg
Een aanpassing van de beroemde Drake-vergelijking zou de schattingen van intelligente beschavingen in onze Melkweg radicaal kunnen verfijnen.

There ARE better ways to communicate across vast reaches of the cosmos than sending gold-plated copper records: radio waves, for instance. That's what SETI is on the hunt for.
SETI has a lot of shared history with the Voyager record. One of the record's precursors was the Arecibo message, which is the kind of signal that SETI would love to find.

I just gave a talk about the ALMA telescope and its development program to my ex-colleagues at SKAO, and I just wanted to share two wonderful resources that I found. The first one, is the NRAO Archives, which includes things such as this interview with Frank Drake (yes, the one that came up with the Drake Equation for the probability of the existence of life we could communicate with in our galaxy):

RIP.
"On Friday, the family of astronomer Frank Drake announced that he passed away peacefully at 92 in his California home, near the site of his final academic position at the University of California, Santa Cruz. [...] Drake is probably best known for an equation that bears his name and his subsequent involvement in SETI efforts"

And for him to have seen the rise of exoplanet science and detection techniques in his lifetime, it must've seemed like the mist around his #DrakeEquation was beginning to dissipate a little bit.
It brings some clarity about how many stars have planets. We are beginning to realize that it's probably not a small fraction after all. It may even be all of them. That's quite a step forward.

Pretty sad to have lost #FrankDrake today.
When you look up at the night sky, if you have a physics background, or even if just a science enthusiast, you can't help but think about the Drake equation.
It's quite a legacy to have changed the way people ponder the universe and our place in it.

Nadia Drake on her dad's (Frank Drake) famous equation and the work to 'fill out' the equation.
“Dad, did you ever imagine that your formula would become so famous?” I ask the kind-eyed, 91-year-old person next to me on the patio.

Nadia Drake on what the Arecibo telescope meant to her and her family. She is the daughter of astronomer Frank Drake (originator of the Drake Equation).
"The Arecibo Observatory was not only a window to the universe, but also a treasured second home to the Drake family."

Nadia Drake (the daughter) on Frank Drake (the father). 🙂
"“Searching for intelligent life was considered bad science in those days,” says [Frank] Drake, who just turned 90 years old—and is better known to me as Dad."
