We live in a place where William Shatner will narrate the eclipse, not a scientist.

You can stream TV to watch the 8 April 2014 eclipse starting at 1 p EST. There is an English version, Spanish version, and silent version that will be available.

There will absolutely be scientists in this stream.

Don’t look at the sun. Make a pinhole projector and observe the shadow of the eclipse if you are without glasses.

Einsteins predicted that massive objects like the sun should bend light with their massive gravity. Photos of stars at night versus during an eclipse show this effect.

NY times old headline “light all askew in the heavens”. Illustration picture on right of the position of two stars during the eclipse is slightly different than at night. Shows Einstein general relativity prediction that suns gravity bends light beams correct.

Past s also helped early scientists figure out the element .

“Jules Janssen, was a French astronomer who, along with English scientist Joseph Norman Lockyer, is credited with discovering the gaseous nature of the solar chromosphere, and with some justification the element helium.”

"Pedestrian Head Starts, also called Leading Pedestrian Intervals ( s), are a known and proven safety intervention used around the country. These give pedestrians the walk signal several seconds before drivers get a green light, 🚦so can begin crossing the street before drivers start to turn. This makes the more likely to see & stop for them.

Studies from other cities have found reductions in pedestrian crashes and near-misses... as much as 60%"

@enobacon

LPIs scare me because drivers know there is no cross traffic when the light first changes and thus we have chronic fresh red light runners.

If you visit nyc, be super careful about crossing Broadway (busy street) from a less busy street because you might get run over.

Here comes Byron's DGAF, stinking his way past two schools and over a hill to avoid some traffic signals on the way to make a U-turn and then fill a yard with fumes on the other side of the neighborhood.

When covid first hit and everyone was abandoning NYC. And we didn’t know how to treat it. And we weren’t quite sure how easily it spread.

And our Upper Manhattan nursing homes had 15% death rates,

Jose Andres and WCK were there all over NYC, working in spite of fear even in MY neighborhood in Upper Manhattan.

I respect — and donate — to WCK probably the most.

What a horrible day.

Gone are the days when I would have a ticket and jump on the next train with no change fees. Trains are now full.

Biden said feds should use rail over air…
But is it us making it crowded? (Anyone analyzed this?)

Is sold out ‘perfection’, or do we need a lot more trains?

As I told NBC News:

“If we’re serious about reducing greenhouse-gas emissions, we have to be serious about reducing transportation emissions, and in order to do that we have to address the main source of those emissions, which come from cars and trucks on highways."

“And to that extent, we need to rethink how much we want to expand highways.”

Drivers should receive an automatic fine for stopping in bike boxes (i.e., Advanced Stop Lines), designed to give cyclists a safe place to stop and allow them to be in front of cars so they have more time to go when traffic lights change.

This is a Sharrows? Aren’t these more dangerous than no paint at all?

Maybe the city engineers can have some of those fines as well.

So I booked a flight for next week, the first time in quite a while

At first I was looking at United, but a lot of their planes were Max 8s or Max 9s, or just Boeing in general, and I was like ... do I realllllly want to roll those bones

Then realized Delta flew the same routes but with Airbuses

So: Delta

I wonder how many other people are making these sorts of calculations?

Not too many, I'd suspect, but not zero

I can’t remember if there is a passage in the book, but Inwood neighborhood lore is that he waited until an early holiday morning to destroy Inwood Hill Park because the neighborhoods of Inwood and Spuyten Duyvil were actively protesting it.

At least there are two places to cross to the other side of the highway.

But the noise and chaos of a highway in an otherwise place of refuge is 💩
