100,000 flights per day at altitudes from 25,000 to 40,000 ft, mandating a tiny amount of sulfur in the aviation fuel could probably halt and reverse global warming.
The point of this post is to make you think - there's a 100,000 flights every day at high altitude. They will be burning and spitting stuff into the atmosphere.
Is there some compound or substance that can be included that would dramatically counter-act CO2 greenhouse effect?
The answer is: almost certainly, yes. What are its second order effects? Is Sulfur Dioxide the best choice? These are important questions to determine. All we know right now is - SO2 had a dramatic effect on warming when it was emitted by ships.
Any which way you slice it, the fastest way to deploy a solution to an industrial scale problem is to use industrial scale distribution. Planting a tree and recycling a pop can will make you feel better.
If you want to actually change the world, change industry.
This was all a pretty off-hand tweet but it turns out Scott Kirby, CEO of United Airlines, suggested SO2 injection into aviation fuel as a climate change tool last month in an internal all-hands meeting.

What looks to be a bug in a video game making a person hold the pistol sideways - like a gangster - actually reveals something subtle about the shape of space.
It has implications from CAD design to Black Holes + anti-gravity. Differential geometry + parallel transport 🧵
Differential geometry is the mathematics of curved surfaces. Euclidean geometry is the 'nice' flat space - where moving along a direction doesn't change the absolute orientation of your perspective.
In curved space, however, this changes.
In both CAD design programs and first-person shooters, the view is inscribed on the surface of a sphere. In CAD its looking inwards, for an FPS its looking outwards.
Yet our mouse controls are Euclidean vectors mapped onto the surface

Biology evolves to the limits of thermodynamic efficiency, and we know from hardware engineering sending current down a wire is terribly inefficient compared to an optical waveguide.
Photonic computing is the future, and our brains might be doing it already 🧵
Computing means processing information, and Landaurs limit describes the thermodynamic minimun of entropy generated by overwriting a single bit of information.
The entropy cost only goes up as you include the non-reversible processes of mobile charge carriers dissipating heat
Getting more efficient computation means wasting less heat, beating the Landaur means making the computational steps information-preserving.
