@DukeBarvo @fasc1nate Thanks. I came around to realizing this a little after I posted this question. Notably, these falls are not the horseshoe falls.

@MeidasTouch That duck is basically America right now: trapped in the toxic swamp Trump created, surrounded by algae, bad decisions, and a government that keeps painting over the mess instead of cleaning it up.

Paddle on, Duckie. ✊🏿🥰

@for_built @archeohistories Also if the bottom image were to be real, there should be a crossbar between the two supports, or else the pillars would tilt toward each other over time.

@Shabbirkhan101 @historyinmemes Is this what you're referring to? https://t.co/Nrxts2RsCg

@jedinorseman @magicman32 @TheCinesthetic It's trash. I wouldn't call it woke.

@wiggityp @AMAZlNGNATURE When the person in charge of enforcing the laws is the one breaking them, he can do whatever he wants. Whoever decided this is the way it is should go is crazy.

@Ricko276112801 @Dr_TheHistories Did you know that depending on which gospel you read of the two that have nativity accounts, Jesus was born either some years "before Christ" or some years "in the year of our Lord"?

Tell me more about how that makes sense.

@OliverJack77366 @PhysInHistory According to whose geometric observations? Eratosthenes knew the world was round and estimated it's size. That's something you can't do if the world is flat. https://t.co/FPp3jFMdam

It has to be so exhausting defending Donald Trump.

It doesn’t matter if Iran is getting destroyed militarily. The U.S. military is the best in the business.

But If the objective is opening the straight of Hormuz, then we are not winning.

@st_ataraxia @HenrykAbram @PhysInHistory Trigonometry, for one. Given two sticks of the same length, holding them plumb at two locations at a specific time of day at a specific time of year, the lengths of the shadow can yield some sense of how large the radius is and therefore circumference, etc.

Science is the gradual discovery of more. In the Western Hemisphere, Anaximander in the 7th century BC hypothesizes that the Earth is a cylinder, but unlike the image, humans live on the flat top of the cylinder. 6th century BC: Pythagoras creates the hypothesis that the Earth is a sphere.
4th century BC: Aristotle formulated scientific proofs of sphericity, based, among other things, on the observation of the Earth's circular shadow cast on the Moon during an eclipse.

3rd century BC: Eratosthenes of Cyrene made the first measurement of the Earth's circumference in the East, in India, because it was easy to read texts.

@OliverJack77366 @PhysInHistory I think more accurately, if he thought he knew how large the cylinder was, it would be based on geometric observations, not based on the content of the maps of his day. From there one would probably have guessed how much is missing from their maps.

@cliftoniusmax @Sci_Nature0 It's not like Jupiter's orbit being exterior to Earth's orbit is some kind of shield. It depends on the position of the planets at the critical moment. And if the planet is in the wrong place, Jupiter's presence could conceivably be more dangerous.

[Dr. M.F. Khan @Dr_TheHistories]

A new DNA study has revived a long‑running theory that Christopher Columbus may not have been Italian at all, but actually Pedro Álvarez de Soutomaior, a Galician nobleman also known as Pedro Madruga. Researchers compared genetic material from remains believed to be linked to Columbus with DNA from documented descendants of Madruga’s family line, finding striking similarities.

This theory argues that Madruga disappeared from historical records after a regional war in Galicia, the same moment Columbus suddenly emerged in Portugal with a new identity, nautical expertise, and connections that would later launch his Atlantic voyages.

Supporters of the theory point to additional clues: Columbus named over 100 places in the Americas after Galician towns, and 80 handwriting experts have concluded that Columbus’s writing style is virtually identical to Madruga’s.

If true, this would radically reshape the accepted biography of one of history’s most famous explorers, suggesting he may have concealed his origins for political survival. While the theory remains debated, the new DNA evidence has pushed it further into mainstream historical discussion.

One of the strangest supporting clues is Columbus’s 'obsessive use of Galician‑Portuguese language patterns', even in private notes. His letters contain idioms, spelling habits, and grammatical structures that do not match Italian dialects of the era but align closely with the writing of nobles from southern Galicia.

Even more intriguing: Columbus repeatedly used Galician nautical terms that were not common in Genoa or broader Italy, but were standard among sailors from the exact region where Pedro Madruga ruled.

Linguists argue this is nearly impossible to fake, especially for someone supposedly born and raised in Italy, and it quietly strengthens the case that Columbus was hiding a past tied to Galicia’s political conflicts.
