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: 🧵 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.

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.

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

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

Extraordinary Claims Require Extraordinary Evidence.

A news story broke there's massive structures beneath the Pyramid of Khafre, something far beyond the tech level assumed of ancient Egyptians.

What can back these claims? Extraordinary technology: Synthetic Aperture Radar🧵 First lets start with optics - in general a larger lens lets your resolve finer and finer details.

Roughly, the angular resolution goes like wavelength/diameter.

This makes sense if you think about how waves are diffracted - smaller waves or larger opening, less diffraction

The greatest crime against humanity in history was committed in broad daylight.

+ Seven million dead
+ 70% of the world population injected
+ Civil liberties suspended
+ 13 trillion $ printed
+ Inflation and economic destruction
+ Intentional cover-up

Send them to the Hague This is more spending than all major wars the US was involved in, combined. A death toll greater than the Holocaust.

Is this a conspiracy theory? No. An 8-month investigation CONCLUDED that Echo-Health Alliance engaged in gain-of-function research in Wuhan, China

A neat coincidence is how the Earth has naturally resonant frequencies if you think of the ionosphere as an electric 'drum', and this frequency range corresponds to the brains frequency of operation while meditating

Whats weirder is how solar activity might affect how you feel
There are some theories of consciousness that posit it inherently depends on the synchronization and resonance of electromagnetic fields across the body, so, not just neuronal firings but the fields those firings produce, across the somatic nervous system, vagus nerve, etc

Here are are two statements that seem obvious:

- There is a single objective reality
- Things outside your future light cone can't affect you

Yet quantum mechanics breaks at least one of these

Here's why Wigner's Friend thought exp. shows reality is stranger than we think 🧵 The setup is simple:

One person is in a lab making a measurement of a particle either spin up or spin down

Someone outside is waiting to hear the result. To the person outside, the lab is one big quantum system in superposition of two states

This is the most interesting physics paper I've ever read.

Maxwell's original equations have been greatly simplified to leave out an important part: Scalar Waves.

But the CIA already knew this.

If you want to know how electro-gravitic drone propulsion works, this is it: 🧵 Maxwell originally wrote out 20 equations in quaternion form which were then simplified into the familiar vector equations we all learn in undergrad physics that look like this.

The equations are the basics of all modern electronics, telecoms, power, energy, etc.

"Stigma" is how a small minority can persuade a large majority to not pursue the truth when it would be inconvenient to that minority.

There are many topics that are now too-stigmatized to discuss openly even when that discussion would be in everyones long-term benefit. 🧵 This is especially true when it come to the origins of crime and inequality in society. There are many explanations for the observed outcomes that are not investigated scientifically because they are politically untenable or deemed too offensive.

This could be an incredible revolution in Cosmology.

The Dark Energy model of the universe, which won a Nobel Prize in 2011, may be completely wrong.

The accelerating expansion instead is simply because time runs faster in the voids between galaxies.

Let me explain: The standard workhorse of cosmology for the last 25 years has been the Lambda Cold Dark Matter (ΛCDM) which assumes the universe is roughly homogenous.

Originally Lambda was Einsteins 'fudge factor' to explain why the universe wasn't collapsing under its own weight

Quantum Computing can revolutionize our ability to simulate the natural world

Yet a lot of QC experts have given up and moved to other industries, believing a useful QC platform won't be here until <2040.

Can QC be saved this decade? Yes.

Here’s my contrarian QC thread 🧵 Quantum mechanics dominates the world of the very small, but determines properties we measure macroscopically. Nowhere is this more important than materials science.

Yet simulating crystal formation is a profoundly difficult task for classical computing. Why is it so difficult?

There's 40+ fusion companies and they all claim they'll be first

To be first you have to burn DT fuel - the absolute worst choice for economic energy production

The best long-term approach burns pB11 - yet no traditional approach can do it

Here's my contrarian fusion thread🧵 DT burns at the lowest temperatures but what it releases is horribly nasty: a 14 MeV neutron that takes a solid meter of metal to fully shield.

This means your magnets are further from the last-closed flux surface of the plasma, demanding more current to operate

One of the biggest mysteries of biology is why life on Earth has a specific chirality: left-handed amino-acids and right-handed sugars

This is less surprising if you consider that amino acids come from stellar nebula

The building blocks of life then 'rain down' onto planets 🧵 Spectroscopic analysis of stellar nebula has found the presence of amino acids in large enough quantities to be detectable at astronomic distances.

These form by a simple reaction of methane, ammonia and formaldehyde by exposure to ultraviolet radiation even in absence of H2O

It should be abundantly clear that in the face of falling birth rates, robotics, automation, and AI will step in to fill the gap.

But these agents have no access to a SSN or bank account - they'll have to use blockchain for everything. This is the start of the Economy 2.0 🧵 In almost every developed nation on the planet birth rates have plummeted in recent decades, often falling below replacement-levels.

Meanwhile governments are starting to re-think their immigration policies in both the US and Europe due to recurring issues of integration

Archeologists just found ancient highly advanced stone structures in West Java radiocarbon dated to be between 27,000 - 16,000 years old, drastically upending our theories of human civilization.

Along with Gobli Tepeke it seems like our entire conception of history is flawed 🧵
This study made extensive use of Electrical Resistance Tomography to reconstruct subsurface features, chambers, and structures leveraging high sensitivity measurements, spacing metal electrodes in a 3D grid to measure the entire area and reconstruct it volumetrically

My last job was as Senior Stellarator Engineer at an early stage fusion startup. I was the lead design 'ideas' guy for stellarator systems - here's some things I learned about the art and science of stellarator design 🧵

First off, a stellarator is indeed a work of art: Like Tokamaks stellarators have a kind of periodic symmetry in the coordinate space of the magnetic field enclosing the plasma, but, unliked Tokamaks this doesn't translate into nice symmetries in our 3 dimensions.

A Stellarator is every CAD designers nightmare

Collectivism has a natural advantage over individualism in political fights because every cell of the collectivist body politic is programmed to fight against unorthodox views, while individualism naturally defends diversity of perspectives 🧵 Under collectivism, there is only one acceptable narrative and any departure from that is viewed and then portrayed as an existential threat to the entire society.

To be contrarian is to be a threat to the "progressive revolution" and painted as counterrevolutionary

People think socialism is liberation for the working class but the underlying premise is the State knows what's best for the Individual, so really it's just economic enslavement by a political elite.

Engineered scarcity and fear to keep everyone playing zero sum games. 🧵 The people advocating for greater government control are all politicians that put up a narrative that it's in the best interests of everyone because the world is too dangerous and we cant trust individuals to exercise their liberty judiciously.

So you should take it away.

The thermodynamics of industrial capitalism demands energy to keep growing.

But our economy isn't setup to be an energy-producing machine, it’s a money printing machine, money backed by nothing.

Fiat currency and its implications have been a disaster for the human species 🧵 The US Dollar has been devalued by 25% in the last four years. The government is printing its way out of a short term deficit into a longer term one.

It wasn’t always like this - money used to be backed by something, such that the government couldn’t just issue it arbitrarily.

Former RF engineer and superconducting magent engineer here - along with finding that microtubules have perfectly diamagnetic cores, a sign of superconductivity, it means that a highly structured superconducting tubule network can act as a quantum-limited noise floor RF antenna.

https://twitter.com/sterlingcooley/status/1757802109293261245

The sensitivity of an antenna is ultimately limited by the resistance in the conducting wire, because thermal motion of the charge carriers produces voltage noise. The temperature and resistivity set the noise floor of measurement sensitivity
