What Physicists Don't Know About Electromagnetism
Hans G. Schantz
LibertyCon June 23, 2023
In the 1940s, physicists and engineers alike used Stratton’s Electromagnetic Theory as their text. They learned about such applied topics as simple antennas, waveguides, arrays, even radio wave propagation over the earth. Today, physicists use Jackson’s Classical Electrodynamics. There’s still material on simple antennas and waveguides, but nothing on arrays and the only practical case of radio wave propagation mentioned is Schumann resonances.
Since WWII, physicists have been pursuing and refining "Quantum Electro-Dynamics," or QED, a dubious perturbation theory that has delivered 12-digit agreement between theory and experimental measurements of the electron, but fails to align with the properties of the electron's heavier cousin, the muon.
Meanwhile radio scientists and electromagnetic engineers have taken Schelkunoff’s concept of “impedance” and put it to work in a host of practical applications understanding transmission and reflection of microwave signals. They’ve worked out link laws that describe what fraction of energy makes it from a transmitter to a receiver, or reflects from a target in a radar system. They’ve worked out fundamental equations for physical limits on the size and performance of small antennas.
What else don’t physicists know about electromagnetism?
And what implications does it have for our understanding of how the world works?

The Mountain That Chooses Who Lives
Hidden deep within the Himalayas, Annapurna I (8,091 m / 26,545 ft) stands as one of the most feared and respected mountains on Earth.
It’s not the tallest but it’s one of the deadliest.
With a fatality rate of nearly 30%, Annapurna has claimed more lives than any other 8,000-meter peak.
Its slopes are unpredictable avalanches, collapsing ice walls, and storms that appear from nowhere.
Climbers say you don’t conquer Annapurna you survive her.
It was first climbed in 1950 by Maurice Herzog and Louis Lachenal, becoming the first 8,000-meter mountain ever summited.
But the victory came at a cost , frostbite, amputations, and near death.
Since then, every expedition has carried the same truth: on Annapurna, the mountain decides who returns.
Annapurna isn’t just a peak, it’s a test of surrender, courage, and faith.
She reminds every climber that sometimes the greatest summit…
is making it back alive.

TIL Alan Turing feared losing his savings if Germany invaded Britain, so he used the money to buy two 90 kg silver bars, buried them in the woods, and wrote down the location in code. Later on when he wanted to dig up the silver bars he was unable to break his own coded message and never found them.

"This effect has been seen again and again. When radicals threaten disruption, authorities often seek compromise with the moderates who seem like the only alternative. Labor unions were accepted to prevent worker councils. Environmental Defense Fund got a seat at the table after Rainforest Action Network threatened chaos. Violent radical flanks, like the Deacons for Defense and Justice, protected nonviolent activists such as MLK and allowed their protests to proceed without lethal state repression. Political movements that succeed almost always include an extremist edge. The radical flank creates space and the moderate fills it.
"Long before it had a name, the Left had intuited the existence of the radical flank effect, axiomizing it with the slogan “No enemies to the Left.” It’s why the Left doesn’t disavow its extremists. It’s why the Left proudly wears Che Guevara t-shirts. It’s why the Left gives their extremists prestige positions at universities. It’s why the Left, at most, just keeps quiet when the crazy comes out of the mouth of its craziest.
"And that’s a big part of why they’ve win, and we’ve lost, generation after generation, in the culture war. They realized that every time we sidelined our extremists, we inevitably shifted the Overton Window towards the other side, towards their side."

Breaking: Zelenskyy Counts Record 25,000 Russian Losses in October—Pokrovsk Turns Into a Mass Graveyard
Ukrainian President Zelenskyy reports 25,000 Russian military deaths in October, primarily around Pokrovsk, amid ongoing fierce engagements.
Breaking: In October, around 25,000 Russian soldiers were confirmed killed on video, with an additional 2,000–3,000 estimated casualties not captured on camera—the highest monthly toll since the start of the full-scale invasion in February 2022, President Volodymyr Zelenskyy said during a meeting with press on November 7.

🇷🇺🇺🇦 Almost two battalions of the Ukrainian Armed Forces surrendered near Pokrovsk in a month.
About 700 Ukrainian soldiers surrendered near the almost encircled Pokrovsk – this is a record since the beginning of 2025, some media report. According to other data, the number of prisoners may reach up to 1000 people.
Fewer and fewer garrisons are trying to resist: columns with fuel and ammunition were destroyed by our drones even before reaching the city, and the Rodynske–Pokrovsk highway is already being called the "second road of death."
During the battles for Pokrovsk, according to various estimates, more than 6,500 Ukrainian soldiers have died, and more than 5,000 remain encircled now.
Meanwhile, Kiev stubbornly lies that there is supposedly no encirclement.

Russia Takes Pokrovsk
The significance of the Russians taking control of Pokrovsk is that it was the last fortified position between the Russian front and the Dnieper River, which I have always believed to be one of the Russian’s primary objective. Given the nature of the terrain to the west of the city, it should take very long […]
