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.

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.
How long is the coastline of Britain?
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.

The most fun you can have in science is when someone discovers something that nobody can explain. It’s been a long time since we had that kind of fun in particle physics. In particle physics we’re usually running experiments to test what we think we already know.
Astronomers and astrophysicists get to have all the fun today with the announcement of the “giant mysterious object” named Himiko, after an ancient mysterious Japanese shaman-queen.
Light takes time to travel across the universe. Astronomers figure Himiko existed when the universe was an 800 million year old toddler. According to existing models of the Big Bang, small clouds of gas formed first and then took time to coalesce into bigger clouds that eventually formed galaxies and stars.
Is Himiko a proto-galaxy? Is there a black hole inside? Is it going to change our understanding of the Big Bang?
Whatever the answers are, one thing is sure — many research projects will be launched, seminars given, papers published, and young careers shaped, before the puzzle of Himiko is solved.
