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.

The Earth's magnetic field is rapidly weakening, making our planet less shielded from solar sunspot cycle and coronal mass ejections

Solar sunspot cycle is strongly correlated with wars and civil unrest throughout history (and diseases, unemployment, etc)

We are at the max 🧵 Image
Image
Image
Image
The current sunspot cycle is near its maximum, right now, as we enter 2026.

Meanwhile the decline of Earth's magnetic field strength is accelerating.

This is especially true in South America right now. Image

"That doesn't make sense! How could the Sun influence human behavior?"

The Earth has an ionosphere which acts as a giant resonant cavity for low-frequency electromagnetic waves.

This Schumann resonance is at the same frequency as Human alpha and theta brain waves Image

Up until Minnesota the largest medicare fraud in history was run by....

A guy who used oxycontin and fentanyl to get patients addicted so they remained in his nursing homes.

Trump pardoned him in 2020.

$1.3 billion in fraud by one person.

Presidential Pardon. Image
People who think this is 'whataboutism' are too partisan-addled by years of divisive thinking. Fraud is everywhere, supported by all political parties, that you will not get justice for these crimes against the public unless we investigate and expose them ourselves.
*sentence commuted. I don't know why you'd commute this sentence. Seems like a pretty horrible person.

Threaded fasteners are among the most commonly manufactured components in world history.

Yet almost nobody understands how they actually work.

This makes you look retarded and incompetent, an abysmal failure, and kills people who trust you.

So listen up: 🧵 Image
The first thing to understand is this:

A bolt is a spring. It applies force by being stretched.

That means it needs to stay within the linear elastic regime of the stress-strain diagram.

"wow" you think. "I never knew that." Of course you didn't. Its not even 1% of bolt-physics.Image
The effective spring constant of a bolt comes from the part of the bolt that is not engaged with any threads.

The clamping force of a bolt is generated by stretching this un-engaged part.

This is why some bolts have an unthreaded shank portion that bypasses threads.Image

For all of history the engineering limits in every domain are set by the materials we have learned to master.

Self Driving Robotic Laboratories and AI-Accelerated Science

Will create a new Golden Age of Material Science

Starting Now 🧵 Image
The epochs of civilization have been demarcated by materials for good reason.

Steel cuts through the Bronze breastplate. Gunpowder cannons toppled walls of Stone.

Today, Silicon powers our information economy and the rise of AI Image
Silicon is just the beginning.

New computing substrates. Composites. Catalysts. Synthetic Fuels. Smart Textiles.

Every aspect of our built environment is poised for revolution.

This isn’t just a product category. It’s a new Golden Age for good reason Image

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 🧵 Image
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. Image
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 Image

There's this toxic and paralyzing interlocking set of narratives that hijack social empathy into vicious in-fighting.

It poisons the well of public discourse, stagnates economies, in exchange for vapid virtue signaling and paper trading progress.

I call it "The Blight" 🧵
The Blight shields itself from direct criticism by installing hair trigger victim complex in it's adherents, who decry any deviation from it's central narrative of mandated equality of outcomes

Beauty, success, pride, are all immediately equated to Fascism

Strength is a crime Image
Image
Image
Image
The primary tactic to hijack empathy is, like a shitty LLM, endless semantic inversion.

The Patriot Act defends the constitution by defiling your constitutional rights.

The UK Online Safety Act protects children by banning talking about pedophile Pakistani rape gangs.

Etc.. Image
