So happy to bike by my local independent bookstore to get Life After Cars and chocolate.

Having just cycled in the city I’m starting with half a bar & Part III: How we get free. @thewaroncars.bsky.social
A long tail cargo bike with the Life After Cars books and chocolate bar resting on the pannier. Of course a parked car is in the background because free street parking is a plague 🙄 Holding the book open to ‘How we get free’ with an oat milk bar and a cargo bike and bike lane in the background.

Grueling semester so far but I’ve picked up a new hobby: Sandwich bag.

Someone/something left this bag containing food on an inaccessible ledge outside my lab. All we can do is wait/observe…

Day 34: possible mold developing, the weight still firmly on the edge, wind gusts predicted tonight.
Plastic bag with a hole ripped open containing smaller bags and lumps of stuff on a granite ledge with a black fence directly behind. Wide angle view. Plastic bag with a whole ripped open containing smaller bags and lumps of stuff on a granite ledge with a black fence directly behind. Zoomed in view.

@nypost.com buried the lede 🤦🏼‍♀️

“This bill will make our streets exponentially safer for all: drivers, pedestrians, and cyclists,”

Here, fixed it for you:
Absurdly carcentric NY Post headline “NYC would lose 300 K parking spots and $3 billion on this lefty city Council traffic plan” crossed out with people > cars written below.

Speeding is for people who can't do math.

The majority of car trips in the US are less than 6 miles. If you drive 30 mph instead of 20 mph, you'll only get there 6 minutes earlier but you're much more likely to kill someone. Just leave 10 minutes earlier and drive slower.
An infographic titled "You can't prioritize both safety and speed" visualizes the relationship between vehicle speed and pedestrian fatalities in collisions. The graphic shows three horizontal bars, each representing a different vehicle speed at the time of a pedestrian collision: 20 MPH, 30 MPH, and 40 MPH. Each bar includes a visual representation using icons of people to indicate survival vs. fatality outcomes, along with corresponding percentages. 20 MPH: 1 red icon (fatality), 19 blue icons (survivors) Caption: "5%" in a red circle indicating the fatality rate Visual message: Collisions at 20 MPH have a 5% pedestrian fatality rate 30 MPH: 9 red icons (fatalities), 11 blue icons (survivors) Caption: "45%" in a red circle Message: At 30 MPH, the fatality rate jumps to 45% 40 MPH: 17 red icons (fatalities), 3 blue icons (survivors) Caption: "85%" in a red circle Message: At 40 MPH, the fatality rate rises sharply to 85% At the bottom, the source is cited: National Traffic Safety Board (2017), with a URL link to a safety study document. Logos for "Transportation for America" and "Smart Growth America" are also shown. Main takeaway: Higher driving speeds drastically increase the likelihood of pedestrian fatalities, emphasizing the tradeoff between speed and safety.

Child’s backpack left in cab, awesome driver brought it to the precinct, tracked backpack and got the bag back. Precious stuffed animals and homework recovered.

@thebrianlehrershow.bsky.social you've given air-time to @galebrewernyc.bsky.social's anti-bike rhetoric, yesterday's show demonstrated how biased some NYC journalists are. Pls host @transalt.org for a discussion of safe/equitable/sustainable streets. #CitiesAreForPeople

Climate scientists do critical work.

Final project week again & it’s so lovely to see students creatively craft investigations linking Gen Chem Lab topics to their non-lab lives. #IteachChem

👀 what’s this I see?? It looks like a third book is headed our way soon.

I highly recommend this delightful series - a nice break from doom scrolling. 📚
