26 de julio de 1941. Cuatro I-16 aparecen por sorpresa sobre la base naval de Constanza. Los cazas bombardean en picado los depósitos de combustible y un dique flotante sin dar opciones a la antiaérea. Los rumanos no entienden cómo los soviéticos han llevado a cabo este ataque.

¿Puede un juez español usar en una causa penal el contenido de un teléfono extraído por autoridades fronterizas de EEUU?

La respuesta no es tan sencilla como he leído a unos y otros. Hilo planteando matices. 🧵👇

A Persian scholar finished a single math book in 9th century Baghdad that quietly became the foundation for every line of code running on Earth today.

His name was Muhammad ibn Musa al-Khwarizmi.

The book is called The Compendious Book on Calculation by Completion and Balancing. I started reading about him at midnight and could not believe how many things in my daily life trace back to one man.

Every time you say the word algebra, you are saying his book title.

And every time someone says the word algorithm, they are saying his name.

Both English words come from him. Both are Latin transliterations of Arabic and of his own identity. The man did not just contribute to mathematics. He named it.

Al-Khwarizmi was born around 780 CE in Khwarazm, in what is now Uzbekistan. He moved to Baghdad and worked at a research institution called the House of Wisdom, which during the Islamic Golden Age was the single most important center of learning on the planet.

The caliph al-Mamun hired the best mathematicians, astronomers, and philosophers from across three continents and put them in one building with one job.

Translate, study, and produce new knowledge. Al-Khwarizmi finished his book on algebra around 820 CE. The Arabic title contained the word al-jabr, which referred to one of the two operations he used to solve equations.

When the book was translated into Latin in the 12th century, the Latin world did not have a word for what he had built.

So they kept his Arabic word. Al-jabr became algebra.

The discipline was named after a single Arabic word in the title of a single book by a single man. The deeper insight is what he actually changed about how humans think.

Before al-Khwarizmi, mathematical problems were solved geometrically.

↳ You drew shapes and measured them
↳ You compared areas

The Greeks had built an entire mathematical tradition on visual proofs and physical constructions. It was beautiful and limited.

You could not solve a problem you could not draw.

Al-Khwarizmi did something nobody had done before him at this scale.

He said you could solve any problem using abstract symbols and rules.

↳ You did not need a shape. You needed a procedure
↳ You moved terms across the equation
↳ You cancelled like terms on both sides
↳ You isolated the unknown

He invented the idea that mathematics is a manipulation of symbols according to rules, not a study of physical figures.

That single shift made everything that came afterward possible.

Calculus. Differential equations. Linear algebra. Quantum mechanics.

None of it works if math is locked inside geometry. He pulled it out.

The second thing he did is the one that changed how the world counted forever. He took the Hindu numeral system from Indian mathematics, refined it, and wrote a book introducing it to the Arab world.

That system included:

↳ The concept of zero as a placeholder
↳ A positional notation where the value of a digit depends on its location

Roman numerals could not do complex calculation. Hindu-Arabic numerals could. When his book on numerals was translated into Latin as Algoritmi de numero Indorum, the word Algoritmi was just the Latin spelling of his own name. Europeans started calling the new method "doing algorism," then "running an algorithm."

The word for the most important concept in computer science is literally his name in Latin. The third thing he did is the part that should haunt anyone who works in tech. His method of solving problems was systematic:

↳ Step one, do this
↳ Step two, check that
↳ Step three, if condition A, then do X, otherwise do Y

He wrote down procedures that could be followed by anyone, anywhere, who knew how to read.

The procedure did not depend on intuition or genius. It worked because the steps worked. That is exactly what an algorithm is. A finite, deterministic procedure for solving a problem. He did not just give us the word. He gave us the entire concept of programming a thousand years before there was anything to program.

When Alan Turing built the first abstract model of computation in 1936, when John von Neumann designed the first stored-program computer in 1945, when every engineer at Google, OpenAI, Anthropic, and DeepMind writes code in 2026, they are working in a paradigm that started with one man in Baghdad twelve centuries ago.

The strangest part is what happens when you walk into any tech office in San Francisco or Bangalore or Lahore today.

Engineers say the words algebra and algorithm hundreds of times a day.

They do not know whose name they are saying.

Almost nobody can spell al-Khwarizmi correctly on the first try.

His legacy:

↳ Original Arabic manuscript preserved at Oxford
↳ Book on Hindu numerals survives only in Latin translation
↳ The Latin version was the textbook that taught medieval Europe how to count

The man who built the foundation of the AI revolution did not live to see a calculator.

He died around 850 CE, a thousand years before the first electric current was sent through a wire.

The civilization he built mathematics for collapsed. The library he wrote in burned. His own grave is unmarked.

But every algorithm running on every machine on Earth right now still answers to his name.

With everything we are hearing right now about ticks this seems like good information to share.

“Here’s what I’ve learned after more ticks than I care to count.
First, whatever your uncle told you, forget it. No matches. No nail polish. No Vaseline. No soap on a cotton ball. All of those do the same terrible thing, they stress the tick out, and a stressed tick empties its gut back into the bite before letting go. Which, if you think about what that actually means for a second, is literally how Lyme and the rest get transmitted so you’re not speeding up its exit. You’re making it throw up into you.
Fine-tipped tweezers. Grip right where the mouthparts enter the skin, not the body, the head. Pull straight up, steady, no twisting, no jerking. It’ll feel like it’s resisting because it is, the mouthparts are barbed. Just keep the pressure on and it lets go in a few seconds. If a piece breaks off in the skin, leave it alone. Your body pushes splinters out. Digging around with a needle does more damage then the fragment ever would.
Clean it with alcohol or soap. Wash your hands.
Now here’s the part most people skip: don’t flush the tick.
Tape it to an index card. Clear packing tape right over the body, write the date and where on your body it was, and stick the card in a drawer. If you come down with anything weird in the next 30 days, rash, fever, joint pain, that flu-that-isn’t-flu feeling, that tick goes with you to the doctor. Some labs will test the tick itself, which is faster and often more reliable than waiting for antibodies to show up in your own blood. A dated tick taped to a card is one of the most useful things you can hand a doctor who’s trying to figure out what’s wrong with you.
The other thing worth saying out loud: if the tick was engorged when you pulled it, and you can’t swear it was off your body within 24 hours, call your doctor that same day. Don’t wait for a rash. Fewer than three out of four Lyme cases even produce the classic bullseye. A single preventive dose of doxycycline within 72 hours of a deer tick bite cuts the Lyme odds way down, and most docs in tick country will write that prescription without giving you a hard time, especially if you walk in with the tick taped to a card and a clear timeline.”

Watch for signs of heat exhaustion like dizziness, nausea or extreme fatigue. If someone around you feels unusually unwell, weak or develops a headache, it is best to help move them to a cool and shaded place immediately. Ensure they get water, ORS etc. that helps them. Children, the elderly and those working outdoors are especially vulnerable during extreme heat. Ignoring these warning signs can quickly turn dangerous and may even lead to heatstroke. In such weather, timely care and attention go a long way.
