"Capitalism created the possibility of the win win win. It used to be a zero sum game where somebody won, somebody else lost.
The biggest mistake people make they still think we're in a zero sum world. They're obsessed with some billionaires because Bernie Sanders thinks that @JeffBezos and @elonmusk somehow stole the money from the people.
They don't understand that it's this prosperity machine that's creating more, not just for those billionaires, but for everything that they're touching. They're creating value for their customers, they're creating value for their employees. Their suppliers are flourishing, their investors are seeing their capital go up. It can be reinvested and compound.
All philanthropy ultimately comes from business. That's where the profits are.
Where does all the taxes come from? It ultimately comes from business as well.
This is the engine that's lifting humanity out. The entrepreneurs are the drivers of that engine. Somebody like Elon Musk, he gets a very, very, very tiny sliver of the value that he creates for the whole world."

Vice President JD Vance announces the suspension of the PERM Program for Microsoft:
"Thanks to an ongoing investigation, we have decided to suspend the PERM program for Microsoft, which means they will no longer be able to take those H-1Bs and apply for permanent resident status within the United States of America. Now our message to Microsoft and to any other foreign or domestic corporation is quite simple. We obviously want you to thrive in the United States of America. We want people to invest in the United States of America, particularly the American technology sector. We’re the biggest boosters of your industry. We want you to continue to grow and to employ a lot of people, but we want you to employ American workers. And so our message to Microsoft is, you’re great American company, but you’ve got to hire great American workers. You cannot lay off American workers and then replace them with foreign indentured servants."

Any complex signal hides a secret symphony waiting to be unmixed.
The Fourier Transform, ĝ(f) = ∫ g(t) e⁻²ᵖⁱⁱᶠᵗ dt, acts as a mathematical prism. It translates a noisy wave moving through time into a clean spectrum of frequencies, revealing the fundamental notes that build our reality.

Imagine taking two distant places in the universe and folding the geometry between them until they meet.
That is the basic idea behind a wormhole. Einstein and Rosen found a mathematical bridge between two regions of spacetime in 1935. Decades later, Morris and Thorne asked what a wormhole would look like if its throat could actually remain open.
The strange part is that nothing is being “tunneled through” ordinary space. The geometry itself is doing the shortcut.

Pixels are just numbers until geometry gives them sight.
A grid of raw intensity values passes through sliding filters, extracting subtle edges and textures layer by layer. Through convolution, non-linearity, and spatial reduction, spatial chaos resolves into abstract feature maps.
From millions of isolated numbers, a singular prediction emerges.

Coordinates label a place, but they do not tell us how far apart places are. One degree of longitude spans about 111 km at Earth’s equator and much less near the poles.
The metric supplies the local measuring rule, converting coordinate changes into distances and angles. It lets us describe a curved surface’s geometry without viewing it from outside.

A white dwarf can resist gravity even after fusion stops. Crowded electrons must occupy different quantum states, creating pressure that persists as the star cools.
But this support has a limit.
Near 1.4 solar masses, an ideal nonrotating white dwarf cannot balance gravity with electron degeneracy pressure alone.

Planck time points to a gap in our understanding of the earliest universe. At roughly 10⁻⁴³ seconds, quantum effects on spacetime are expected to matter, so general relativity alone is insufficient.

Covariance Matrix ✍️
When a number of variables are measured at the same time for example, height and weight, or temperature and pressure, or the various pixel values in an image the key question is not merely how much each variable varies by itself but how they vary in relation to one another. The covariance matrix is the full mathematical solution to this question and it reveals the geometric structure that lies hidden within any data set.

Sampling faster than the Nyquist rate does not expand signal bandwidth.
Instead, it spreads quantization noise across a wider frequency band, allowing digital filters to strip away the excess static.
Each doubling of the sampling rate buys clarity - trading speed for resolution.

An electric dipole p(t) = p₀ sin(ωt) ẑ oscillating at a point radiates a field that, far away, falls off only as 1/r.
Its radiation term is E = (μ₀/4π) p̈(t − r/c) sin θ / r along θ̂, with B = r̂ × E / c along φ̂, so E, B and the direction of travel r̂ are mutually perpendicular. The intensity goes as sin²θ / r²: zero along the axis, strongest at the equator.
Every sphere around the source carries the same mean power, p₀²ω⁴ / (12πε₀c³).

🔥 @SecScottBessent puts AI labs demanding government protection on NOTICE:
“You cannot say, ‘We absolve you of responsibility, and the government’s gonna take responsibility.’”
“These labs need to take responsibility for themselves. They can slow down any time they want to.”
