Educators/students: full info on how to use my free Science of the Solar System class can be found here. Useful for high school through college classes. It's a good class. Use it! https://t.co/7qwhqIevBt

Survey alert: Glendale has a new survey for possible bike lanes on Glenoaks. If you live, walk, bike, or breathe in Glendale register your take on this - they're looking mostly for Glendale residents

Pasadena ebike rebates start tomorrow while California's is nowhere to be seen, Americans know wider highways won’t fix traffic, and LADOT wants your input on Highland and Culver: https://t.co/nLsByb0jnS #bikeLA

If you care about children, don’t drive an SUV. Car crashes are a top 3 killer of children in the US (along with guns). And SUVs are responsible for a disproportionately high share of fatal crashes involving children, according to a study from University of Illinois. Buy a

On June 12, @LaurieofMars, director of JPL, which Caltech manages for NASA, and Caltech professor and @plutokiller, Mike Brown, lead the special 100th Astronomy on Tap. Join the free, in person event to discuss our Solar System, play astro-themed trivia, and more.

The lives saved, however, are priceless

Saturday June 3 is #WorldBicycleDay.  Celebrate with the United Nations, the World Health Organization and the rest of the world by riding your bike! @PasadenaCaD2 @PasadenaD7

The Los Angeles River has got to be one of the most underutilized public spaces in North America, right? This could be an incredible linear park with a multimodal greenway that connects the whole city.

I cannot believe we're having our 100th Astronomy on Tap after 7 years! It should be a good one with some amazing speakers including @plutokiller and @LaurieofMars --see you there!

No spoilers, ok?

I'm finally getting around to binge-listening @TheWarOnCars podcast from the start and I'm near the end of 2019 and they have NO IDEA the massive car experiment that is right around the corner and the suspense is truthfully killing me. Also: go listen. From the begining.

Specific application FYI is to fit the limb shape of a not exactly spherical asteroid where only a limited number of radial points along the limb are measured.

Hey math nerd friends: what's a good set of orthogonal basis function to use to describe deviations from a circle. Like spherical harmonics but 2D not 3. I'm currently defining the radial distance using a Fourier series which works but I wonder if something else makes more sense.

If you left your almost-full journal and a copy of Aurelius’ “Meditations” on the Q train, DM me so I can send them back to you. I know I’d be heartbroken if I lost my diary.

Here we go again.... trying out the blue skyies @plutokiller.bsky.social

No dogs allowed in the pool, man.

Beautiful evening so I declared to my wife that it is Happy Hour in our back yard, made us drinks, and then geez the neighbors immediately start crashing the party.

Icy on the outside. Crunchy in the middle. Nom nom nom.

This is the weirdest Easter Bunny I have ever seen. (Also, truthfully, the largest bear I have ever seen in my backyard.)

Today: "Best stay on the paved bike paths after all of this rain" I was told, "some of the dirt trails in the mountains might be impassable." Also today:

Hahaha equinox not solstice. That's what happens when the full moon wakes you up too early in morning.
