Some of America’s greatest triumphs, like the moon landings or the D-Day landings, succeeded because of science.

The current anti-science campaign by the political class makes zero sense.

Explain to me like I'm 10 years old: Is the Biden tariffs on electric vehicles, batteries, and solar panels coming from China motivated 100% by politics (and maybe racism), or is there some other (more legit) reason to do it?

Florida Governor Ron DeSantis has banned lab-grown meat, saying he will "save our beef" from the "global elite" and its "authoritarian plans".

@Benaresh @infosec812 I didn't know I had TPU tubes until I got a flat and couldn't repair it with my regular patch kit, and no bike shops around had butyl tubes in the right size.

@ai6yr The UK has a lot of wind farms (and they're building more). This one is the London Array, and you can see Gunfleet Sands behind it (closer to shore).

Harold Sverdrup, a well known oceanographer, was born in Sogndal. The unit of water flow in the ocean was named after him (i.e., one sverdrup (Sv) = 1 million cubic meters per second).

Yet there’s no indication anywhere in Sogndal that he’s from here. Someone should fix that.

Well it’s time to head north - and as we do it has decided to snow so our little icebreaker looks like (northern hemisphere) Christmas .. likely no more sea ice or bergs … we likely have some proper waves ahead for the 6 day transit… although there is a path through the waves

No vehicles should be moving through an intersection when pedestrians are crossing.

davidho OP ,
@davidho@mastodon.world avatar

@atthenius @Brad_Rosenheim In London, there’s no turning on red and often when pedestrians have a “walk” sign, all vehicles have red lights. It’s the least they could do for driving on the wrong side of the road.

Just found a new (to me) psychology phrase: "pluralistic ignorance". It refers to people holding one view but mistakenly assuming that the majority of others hold a different view, so they keep quiet. Very relevant for climate change action, where lots want action but think they're in the minority.

@helenczerski I thought it meant being ignorant of things that @pluralistic has said.

Maybe not driving and not causing climate change are the solutions.

You can keep overhead projector transparencies in ring binder sleeves, and use masking tape to conceal certain words. Then you just pull the transparency out of the sleeve to reveal the words.

You can do the same in PowerPoint but it makes the computer screen really sticky.

When those of us who work on CO₂ removal (CDR) meet, it’s apparent that no one wants to do this and no one thinks it’s easy.

It’s far easier and cheaper to stop emitting CO₂.

The fact that some of the smartest people I know decide to work on CDR signals our desperation.

Think about how close these people in motor vehicles are allowed to drive at speed next to people on foot, on bicycles, and in wheelchairs when they have no idea where the boundaries of their vehicles are.
