An English engineer wrote a calculus book in 1910 opening with the line "what one fool can do, another can," and proved that almost everything making math feel impossible was put there on purpose by people who wanted it to stay exclusive.
His name was Silvanus P. Thompson.
He was a physicist, an engineer, a Fellow of the Royal Society, and a professor at the City and Guilds Technical College in London.
He had spent his entire career teaching calculus to working-class engineering students who needed the math to actually do their jobs, and he had watched generation after generation of bright kids walk out of math classrooms convinced they were stupid.
He knew they were not stupid. He knew exactly what was wrong, and he was about to say it in print in a way that would get him quietly hated by every academic mathematician in Britain.
In 1910 he published Calculus Made Easy. He published it anonymously at first, listing the author only as F.R.S., which stood for Fellow of the Royal Society. He did not want his name attached to it until he saw how the establishment was going to respond. Because the prologue of the book was not a polite introduction. It was an accusation.
He wrote that calculus was not actually hard. He wrote that the people writing the standard textbooks were what he called "clever fools" who deliberately took the easiest parts of the subject and presented them in the most complicated way possible, because doing so made them look more impressive.
He wrote that they "seldom take the trouble to show you how easy the easy calculations are" and instead "seem to desire to impress you with their tremendous cleverness by going about it in the most difficult way."
Then he opened the first chapter by telling readers something nobody had been willing to admit out loud. The reason calculus felt impossible was not because calculus was impossible. It was because the symbols had been chosen to feel impossible. The notation looked like ancient ritual on purpose. The Greek letters, the formal epsilon-delta definitions, the abstract limit proofs that opened every standard textbook, were not how Newton and Leibniz had originally thought about the subject. They were a 19th century renovation of the field done by professional mathematicians who wanted calculus to feel like a closed shop.
Thompson refused to use any of it.
He went back to the way Leibniz had thought about it 250 years earlier. The letter d in front of a variable, he told his readers, just meant "a little bit of." That was the whole secret. dx meant "a little bit of x." dy meant "a little bit of y." dy/dx meant "a little bit of y divided by a little bit of x," which is just how steep the curve is going at that exact moment. Integration was the opposite. It just meant adding up all the little bits.
That is calculus. That is the entire subject. Everything else is technique, and the technique only works once you understand what you are doing.
A 12-year-old can follow that explanation. A 12-year-old cannot follow the opening chapter of a typical university calculus textbook. The gap between those two facts is the entire reason most adults walk around believing they are bad at math.
The book became one of the bestselling math books in history. Over a million copies. Still in print 115 years later. Still recommended by physicists, engineers, and self-taught learners as the only calculus book they actually finished. Martin Gardner revised it in 1998 and the foundation of the book did not need to change because Thompson had built it on Leibniz, not on the academic conventions that have come and gone since.
The deeper point Thompson was making is the part that should haunt anyone reading this in 2026.
Difficulty is often a marketing strategy. It is not always a property of the subject. When a discipline is taught in a way that feels impossible, the difficulty is doing a job for someone. It is keeping the field small. It is protecting the salaries and the status of the people already inside it. It is filtering out the kinds of people who would otherwise show up and crowd the room.
This happens in math. It happens in law. It happens in medicine. It happens in finance, in machine learning, in philosophy, in software. Every field has a layer of jargon and notation and ritual sitting on top of a core idea that is usually much simpler than the people inside the field want to admit. The jargon is not there to communicate. It is there to gatekeep.
The way you recognize a real teacher is that they keep stripping the ritual off. The way you recognize someone protecting their priesthood is that they keep piling it on.
Thompson finished his prologue with five words that are the entire spirit of his project. "What one fool can do, another can." He meant it as both a joke and a threat.
If a working-class engineering student in 1910 with no Greek and no Latin and no university privileges could learn calculus from a 200-page paperback, then so could anyone the establishment had been excluding for the previous 200 years.
Most subjects you have given up on were never as hard as the people teaching them needed you to believe. You were not stupid. The course was designed to make you feel that way.
What one fool can do, another can.
The sun is fascinating to watch. This timelapse was recorded using a modified telescope designed to safely observe the solar chromosphere, captured over a period of several hours from my backyard in Arizona.
The entire Earth would be a small dot at this distance of ~93M miles.
Pointillisme was an immersive installation created by Japanese architect and designer Taiju Yamashita. The work took inspiration from the painting technique of pointillism, where many tiny dots combine to create a larger image. Instead of paint, Yamashita used thousands of suspended transparent spheres to create a three-dimensional “drawing” made of light.

Tested some equipment last night after making a few changes to my backyard observatory, hopefully enabling some mind-blowing images this summer.
Not bad. Not bad at all.
Thousands of Roman soldiers slaughtered by the Sassanids were supposedly gathered and dragged into this massive rock carved cavern. 😱
They now sit quietly beneath transparent walkways at the ancient city of Dara in Mardin, southeastern Türkiye.
Seeing an entire army reduced to a chaotic pile of femurs and skulls makes you question the official story of their final stand.
I took 1.7 million photos over 6 days to catch this photo of a commercial jet in front of the sun.
The moment it happened, TWO floating prominences were visible, making this not just my best aircraft transit photo, but one of the luckiest of my career! Videos of the transit 👇
Saturn doesn’t just have rings — it rules an entire miniature solar system.As of 2026, the ringed giant boasts 292 confirmed moons, far more than any other planet, with the number still climbing as astronomers keep spotting tiny new ones. Dominating them all is Titan, a colossal world larger than the planet Mercury. With a thick nitrogen atmosphere, rivers and lakes of liquid methane, and a diameter of 5,150 km, Titan feels more like a planet that got captured than a mere moon.Titan orbits Saturn at a safe distance of about 1.2 million kilometres — well beyond the outer edge of the famous ring system. Those dazzling rings, made of countless icy particles and moonlets, are confined much closer to the planet, while Titan sails majestically around the entire sprawling family of satellites. The sheer crowd of moons — from planet-sized Titan down to kilometer-scale irregular rocks — reveals just how gravitationally chaotic and crowded Saturn’s neighborhood truly is. It’s a dynamic, ever-evolving system where collisions, captures, and gravitational dances continue to shape one of the most spectacular regions in our Solar System.
The reason you are not being hired isn't because of lack of skill or degrees, its because you are a retard no one likes.
Be more likable, it's not difficult. 💯
This is probably the best look at the shockwaves I’ve seen from the latest Starship flight.
Captured from a GoPro I clamped onto a proper camera to record simultaneous video. (I’ll show you the photo the better camera took in the reply)
He places the Younger Dryas in a five-million-year context, noting that few global change events in that entire span match or exceed its severity. The geomorphic reshaping, the redistribution of polar elements, the changes to the biome, all point to something extraordinary. Within that window, he identifies the Hemphillian event as a comparable magnitude shift, but he also notes a series of spikes between glacial and interglacial periods that approach that same level of intensity. What makes these transitions remarkable is their speed: in some cases, the shift occurs within a few years.
He does not claim to have a complete answer for what drives these rapid oscillations, but he lays out the likely suspects. Solar forcing almost certainly plays a role. Impacts from extraterrestrial objects are another factor. And he suspects a terrestrial response from within the Earth itself, a feedback mechanism triggered by external forcing. The picture he sketches is one of a dynamic system where cosmic, solar, and planetary processes converge to produce catastrophic change on timescales far shorter than gradualist models would predict.
I set 7 cameras near the pad for starship’s 12th test flight.
In a first for me, all 7 got INCREDIBLE photos. Here’s a little peak at one… but there are a lot more. I’ll post some of my favorites tomorrow, and release at least one in print.
@thesigmamindset Why do all of these nitwits have to explain everything in reference to BUSINESS SALES?!

I was stunned he didn't say SYNERGY.
