I have a tumblr still

I didn’t realize I still had a Tumblr account.

Since the last time I posted I:

- Started my job at Facebook and worked there for 3 years.

- Moved to San Francisco and then back to New York.

- Made my own app, Lore, with my best friend.

- Got way into D&D and roleplaying games again.

- Started writing my own RPG adventures and self-publishing them.

- Worked at startups, big companies, freelanced, drew tattoos.

- Got tattooed a lot.

- Fell in love, got married.

- Got two cats.

- Survived a plague.

- Gained 30 pounds, lost 40 pounds.

It’s been a pretty crazy 10ish years.

The meanderiness of a river, its Stølum number, is defined as the length the water travels from source to finish (blue curve) divided by the direct distance (red line).  This can change chaotically as a river changes coarse, forming Ox bow lakes. The ratio is often found to converge to (but rarely exceed) 3.14, roughly pi. [more] [code] [thanks] [thanks2]

Chaos and the Double Pendulum

A chaotic system is one in which infinitesimal differences in the starting conditions lead to drastically different results as the system evolves.

Summarized by mathematician Edward Lorentz, ”Chaos [is] when the present determines the future, but the approximate present does not approximately determine the future.”

There’s an important distinction to make between a chaotic system and a random system. Given the starting conditions, a chaotic system is entirely deterministic. A random system, on the other hand, is entirely non-deterministic, even when the starting conditions are known. That is, with enough information, the evolution of a “chaotic” system is entirely predictable, but in a random system there’s no amount of information that would be enough to predict the system’s evolution.

The simulations above show two slightly different initial conditions for a double pendulum — an example of a chaotic system. In the left animation both pendulums begin horizontally, and in the right animation the red pendulum begins horizontally and the blue is rotated by 0.1 radians (≈ 5.73°) above the positive x-axis. In both simulations, all of the pendulums begin from rest.

Mathematica code posted here.

Worth thinking about when animating particles and stuff. Tiny differences lead to huge differences over time. Also, this reminds me of what happens when I try and draw symmetrical bezier curves in Illustrator.

This Is Big: Scientists Just Found Earth’s First Cousin

Right now, 500 light years away from Earth, there’s a planet that looks a lot like our own. It is bathed in dim orangeish light, which at high noon is only as bright as the golden hour before sunset back home.

NASA scientists are calling the planet Kepler-186f, and it’s unlike anything they’ve found. The big news: Kepler-186f is the closest relative to the Earth that researchers have discovered.

It’s the first Earth-sized planet in the habitable zone of another star—the sweet spot between too-hot Mercury-like planets and too-cold Neptunes— and it is likely to give scientists their first real opportunity to seek life elsewhere in the universe. “It’s no longer in the realm of science fiction,” said Elisa Quintana, a researcher at the SETI Institute.
