At the National Ignition Facility. The slogan for which is “Bringing Star Power to Earth”

OK Scientists. This is the kind of shit I’m talking about. Huge-scale, World-changing, God-Directed-Fist-Shaking science.

Let’s get to it.

Astronomers Plan Galaxy-Sized Observatory For Gravitational Waves

While this is fascinating, it’s not nearly as cool as what I’d hoped.

GALACTUS!

Instead:

Gravitational waves should also stretch and squeeze pulsars as they pass by, subtly changing the radio pulses they produce. So by monitoring an array of pulsars throughout the galaxy, astronomers should be able to see the effects of nanohertz to microhertz gravitational waves passing by. The array of pulsars should effectively shimmer as the waves wash over it, like a grid of buoys bobbing on the ocean.

Which is actually pretty cool in its own right.

First Simulation of the Flocking Behaviour of Starlings

Link: First Simulation of the Flocking Behaviour of Starlings

I was talking about Flocking/Schooling/Crowd dynamics this weekend after a trip to the aquarium where I spent (a probably unhealthy amount of) time watching sardines. Specifically our lack of understanding as to how exactly those mechanisms function. I’m glad there’s some progress being made in this field.

…the key advance that has made this simulation possible is the first 3D recordings using stereo photography of real starlings in flight which were published only last year. That’s not for lack of trying but the great difficulty in making precise measurements of position and velocity on thousands of rapidly moving birds simultaneously.
