spin

Spin was fully booked. AGAIN.

I know… I know… I should book it beforehand but if I can’t sleep, I cancel my gym alarm (sleep deprivation and epilepsy are not a good combo) and I don’t want to be the dick who books and then never turns up so I always wait until the morning. It’s never been an issue before… I may have been glaring at everyone walking into the spin studio with extreme jealousy…

Anyways, ran 6km and did 20 minutes on the cross trainer instead. The run was a bit difficult, my seizure bitten tongue is still swollen and running seemed to make it swell more. Sorta messed with my breathing so I just took it super easy. In a way it was probably better that I didn’t spin as I could take things at my own pace!

Feel like my morning posts should always include breakfast so here’s today’s: strawberries, raspberries, yoghurt, chia seeds, granola and my weekly flat white treat! I think I eat more meals at my desk then I do at home…

Bacteria, electrons spin in similar patterns

Scientists at MIT and Cambridge University have identified an unexpected shared pattern in the collective movement of bacteria and electrons: As billions of bacteria stream through a microfluidic lattice, they synchronize and swim in patterns similar to those of electrons orbiting around atomic nuclei in a magnetic material.

The researchers found that by tuning certain dimensions of the microfluidic lattice, they were able to direct billions of microbes to align and swim in the same direction, much the way electrons circulate in the same direction when they create a magnetic field. With slight changes to the lattice, groups of bacteria flowed in opposite directions, resembling electrons in a nonmagnetic material.

Surprisingly, the researchers also identified a mathematical model that applies to the motions of both bacteria and electrons. The model derives from a general lattice field theory, which is typically used to describe the quantum behavior of electrons in magnetic and electronic materials. The researchers reduced this complex model to a much simpler, “textbook” model, which predicts that a phase transition, or a change in flow direction, should occur with certain changes to a lattice’s dimensions – a transition that the team observed in their experiments with bacteria.

“It’s very surprising that we see this universality,” says Jörn Dunkel, assistant professor of applied mathematics at MIT. “The really nice thing is, you have a living system here that shows all these behaviors that people think are also going on in quantum systems.”

At least one full-time member decided that they contributed as much as they had to give to an excellent and visionary rock band, that synthesis that’s become rarer than ever. The reason it stings so much is because Vampire Weekend feels like the last of a dying breed, if there ever was one like them at all. No one else has yet come forth that can filter Paul Simon’s Graceland through electronic spiderwebs and follow a reference to a Lydian king circa 560 B.C. with one to a non-canon Run-DMC album. It’s hard to imagine Vampire Weekend without Rostam Batmanglij, its John Paul Jones and Jimmy Page combined. But we’re going to find out how much of that brilliance is retained now that Koenig’s lost half of his songwriting team. Hopefully it’s going to be more than we fear.

The guys I had the most fantasies about as a child were David Attenborough and Carl Sagan. Really. In school, I would fall for the guy in the back of the class with really thick glasses and the insect collection who told you about the solar system. It’s these people who show you these secrets, like, ‘Do you want me to show you a lot of really strange things that nobody’s ever seen ?’ It just drives me nuts. It gives me 53 hard-ons. That’s what turns me on.
