So Kate and Will have chosen Westminster Abbey for their wedding on April 29, 2011. Among their wedding guests will be some of the greatest lights of British science who are buried in the Nave. The guest list includes Sir Isaac Newton, Ernest Rutherford, JJ Thompson, Lord Kelvin and Charles Darwin.
There could be some drama at the reception if Newton and Darwin get to arguing about religion and science. Newton was a devout biblical literalist who computed the age of the universe as being 6000 years by measuring the “begats” in Genesis. Darwin, on the other hand, gave us the scientific theory of evolution that is still upsetting people of Newton’s religious temperament today.
Sir Isaac Newton, 1689
Since the bride and bridegroom majored in art history in college, they might be more interested in their guests in Poet’s Corner, where Tennyson, Dickens and Chaucer share a cozy nook with Rudyard Kipling and Laurence Olivier.
The Brontë sisters are only commemorated, not buried, in the Abbey, as are Lord Byron, Oscar Wilde, Shakespeare, Jane Austen, and Paul Dirac.
Dirac was well known for his verbal brevity. One apocryphal story learned by every physics graduate student at some time in their education has a student raising his hand during a lecture, complaining that he didn’t understand what Dirac had just said. Dirac replied with a brief, “Yes,” and moved one.
But what Dirac doesn’t contribute to the conversation will be more than made up by Oscar Wilde, who is likely to have guests in stitches with his wry social banter, even though he’s been out of circulation since he died 110 years ago.
It sounds like a simple question. We have maps. We have rulers. So just take out a map and measure! But which map do you use? The problem is, the more detailed a map you use, the greater your answer will be, because a coastline is not smooth. It is jagged. There are river mouths and bays and promontories to account for. The answer changes as the resolution of the map increases. Do you chart a path around each rock? Each stone? What about every grain of sand?
This is not the simple math problem of computing the circumference of a circle given the diameter. As a math problem, this is turned out to be an entirely new kind of beast that its discoverer Benoit Mandelbrot called “fractal geometry.” Mandelbrot assigned a “fractal dimension” to measure jaggedness in general.
Since most things scientists want to study in nature, such as clouds, proteins, galaxies, earthquake faults, are neither tiny particles nor smooth Platonic objects, of course it was important to have some kind of mathematical language for describing them.
Thanks to Mandelbrot, now they have one.
Fractals are also great for generating cool pictures like this one:
Mandelbrot passed away Thursday in Cambridge, Massachusetts. He was an instigator rather than a rigorous investigator, a rogue mathematician who left the proofs for those who followed in his maverick footsteps. He will be missed, but hopefully he’s inspired other rogues and mavericks out there to come and do their bit to shake things up.
One last thing — in the name of alumni pride, I’d like to point out that in addition to all the other famous places in America and France where Mandelbrot worked and studied, he found time to earn a master’s degree in aeronautics at my own alma mater Caltech.
First of all, hearty congratulations to Caltech biophysics professor and alumnus John Dabiri, who studies jellyfish propulsion and does theoretical mechanical engineering, a subject that makes my heart go pitty-pat and makes me long for my days as an engineering major before I switched to physics. He works out of the Biological Propulsion Laboratory at Caltech.
And another hearty congrats to Amir Abo-Shaeer, who left a job in industry to teach high school physics. He’s the founder of Dos Pueblos Engineering Academy. He’s had enormous success in bringing girls into the field, something I can relate to personally as the kind of girl who always wanted to take stuff apart.
You can meet the rest of the 2010 MacArthur fellows here.
I love books like a wino loves wine. So I feel pretty drunk every April when the LA Times Festival of Booksrolls around. Critics say we’re all blond and superficial in Southern California. You can see just how wrong this stereotype is when you’re surrounded by bookworms and lit geeks of all sizes, shapes and cultures at the festival.
Susskind signs the book he wrote about his war with Hawking
As a science geek, I felt morally obligated to attend the Real Science panel on Saturday morning. The panel was moderated by science writer K.C. Cole and featured her fellow science writer Carl Zimmer, odor scientist Avery Gilbert and theoretical physicist Leonard Susskind.
Susskind told the audience he was grateful for the extreme intellectual puzzle posed by black hole entropy, given that his generation in physics was too young to have participated in the great quantum mechanics and relativity revolutions on the Einstein era. Instead they were left to “clean up the mess” left behind by their elders, turning the primitive and confusing subject of relativistic quantum mechanics into the elegant theoretical powerhouse of quantum gauge field theory.
Before I heard Carl Zimmer talk about his new book Microcosm: E. coli and the New Science of Life, I had no idea that the humble and ubiquitous intestinal bacteria E. coli has won twelve Nobel Prizes in science — which is ten more than any multi-celled organism on record.
What scientists have learned about E. coli “challenges our assumptions about life,” Zimmer said. Despite their apparent simplicity, each E. coli cell acts like a distinct individual. If 747s behaved like E. coli, then two identically built planes would exhibit completely different behaviors when you tried to fly them.
Another surprising and philosophically challenging aspect of e-coli is their ability to organize socially into competing tribes that compete for food and make tribal war. I’ve always thought of war as a human behavior that was learned. If even single-celled organisms can organize into tribes and make war, then the instinct for war is an instinct that is basic to life itself.
