Oh wow, so the colonizer Spanish have spent years screaming “Free Palestine”… yet somehow have zero interest in freeing Ceuta?!
What absolute hypocrites…

האמל"ח הכי פורץ דרך במלחמת רוסיה - אוקראינה זה לא רחפנים, זה תקשורת לוויינית זמינה זולה ופשוטה.
בעוד רחפנים תוקפים ומתאבדים זה לרוב תחליף לאמל"ח אחרי מסובך יותר שלא קיים בכמויות הנדרשות, התקשורת הלווינית הזאת היא פשוט סנסציה.
תקשורת מלאה לכל עמדה של כוחותיך, ללא קשר למרחב או תנאים גאוגרפיים.
היות ואלומת התקשורת כי כיוונית והיא בין הטרמינל ללווין זה מאוד עמיד לל"א.
זה זול מאוד, כל טרמינלש של סטארלינק זה כמה מאות דולרים, זה כלכך זול שאפשר להתקין את זה על חימושים חד פעמיים בכיף.
ויש לזה לייטנסי והספק העברה מעולה, אפשר להעביר סרטונים בלייב, להעביר למפקד במפקדה לראות בדיוק מה אתה רואה בדיוק באותו הרגע.
זה מדהים.

It's pretty amazing how both the Spanish far-right and the far-left blame Zionism (?!) for what happened in Melilla and Ceuta.

Zionism is simply the idea of Jews living in their indigenous homeland - the Land of Israel, but it has become a euphemism for blaming Jews for everything you don't like.

This is, of course, an ancient Spanish tradition. My family experienced it first hand.

The obsession against Jews and Israel in Spain has gotten completely out of control.

🚨 JUST IN: The NSW Supreme Court has overturned a decision that excluded the viral video from evidence.

In a major blow for the hateful (former) nurses, the video CAN now be used against them at trial when proceedings begin on Aug. 31.

Justice may finally be served.

@BarakRavid אמות המידה הכפולות אינן תקלה. הן דלק.
הימין הקיצוני צריך את האש: כל הסלמה מקדמת סיפוח, שליטה, וחזון גאולה שנשען על עוד ועוד עימות.
מי שרוכב על חמורו של משיח לא מחפש שקט. שקט הוא האויב שלו.
המדינה משלמת את המחיר, כדי שהם ימשיכו בהזיה.

עמירה הס כותבת: "אין צורך בדמיון מפותח כדי לנחש מה היה קורה לו צעירים פלסטינים, היו צצים בהתנחלות אריאל... אם יהודי היה יורה ופוגע בפלסטינים, זה לא היה נקרא פיגוע. מעבר לכך, אם רק אחד מהצעירים הפלסטינים היה חמוש – כל יהודי שהיה ממהר להרוג אותם היה מוגדר גיבור. כיבוש צבאי בן 60 שנה כרוך בייצור של אמות מידה כפולות ומכופלות תוך התכחשות מוחלטת לקיומן"

[The Curious Tales @thecurioustales]

In 1997, a footballer accidentally proved a physics principle in a soccer game that had been invisible for 300 years.

Roberto Carlos lined up for a free kick about 40 yards from goal during a France versus Brazil friendly match in Paris.

The ball sat exactly where a free kick should sit, the French wall stood between him and the goal, and everyone in the stadium knew what was about to happen. Carlos was about to attempt something that shouldn't exist in physics.

He struck the ball with his left foot at an extreme angle, nearly perpendicular to where the goal actually was. The ball curved so dramatically through the air that French goalkeeper Fabien Barthez literally didn't move. He watched it arc impossibly wide, certain it was going nowhere, his body language screaming "that's out." Then the ball bent back toward goal like it was magnetized. It crossed the goal line before Barthez could process what his eyes had just witnessed. Goal.

The stadium went silent for a second.
Then chaos.

That moment became legendary not because it was a beautiful goal, though it was, but because it revealed something about physics that most people had never actually *seen* in real time before. The ball had broken the straight line. It had obeyed a force that existed entirely in the air, invisible to the naked eye, bending space itself through sheer rotation.

That force is called the Magnus effect, and it's been hiding in plain sight in sports for over a century. Every curveball in baseball, every spinning tennis serve, every banana kick in football, every slice shot in golf. They all ride on the Magnus effect. But Carlos's free kick was different. It was the perfect storm of velocity, spin rate, and distance that made the force so visually obvious that even people who'd never heard the word "Magnus" understood something supernatural had just occurred.

Here's what actually happened in the physics.

When you strike a spinning ball with enough velocity through the air, the rotation creates a pressure differential on either side of the ball. The side spinning with the direction of motion builds up a layer of fast moving air that stays attached to the ball's surface. The opposite side spinning against the direction of motion sheds that air layer and creates lower pressure. You end up with higher pressure on one side and lower pressure on the other. Bernoulli's principle then drags the ball toward the lower pressure region. The ball curves.

That's the Magnus effect in its purest form.
It's fluid dynamics.

But here's where most explanations stop and where most people fail to grasp the real picture. The Magnus effect is *proportional* to the spin. Double the spin rate and you approximately double the curvature. But it's also proportional to the surface area. A larger ball, all else equal, experiences more Magnus effect than a smaller one. And it's wildly proportional to velocity. Lower the speed too much and the curve becomes almost nonexistent. Add speed and the curve amplifies. This is why a baseball pitcher's curveball becomes more dramatic at higher velocities, why a tennis serve curves more than a lob, and why Carlos's free kick had to travel at a certain speed to work.

Carlos struck that ball at precisely the intersection point where spin and velocity aligned to produce maximum curve over that distance. Any slower and it lands straight in the wall. Any faster and it overcorrects and misses wide. The goal was practically a mathematical solution to an equation nobody needed to solve except his foot somehow did it perfectly.

The reason this moment matters beyond football is that it made visible something that had been operating invisibly in physics and engineering for centuries. The Magnus effect powers helicopter rotors. It's why airplanes have wings. It's why you can throw a frisbee and it actually stays airborne instead of just dropping like a stone. Every spinning object moving through air experiences it. Every sport that uses a ball depends on it.

Yet most people go their entire lives without consciously recognizing this force exists.

What Carlos did was compress a century of physics education into three seconds of visible reality. He created an experiment that couldn't be ignored or dismissed or explained away. The ball curved. The goalkeeper saw it. The universe didn't change. Nothing magical happened. Just matter responding to force across empty space in exactly the way the math predicted.

The interesting part isn't that it worked. The interesting part is that we'd organized the entire sport of football for decades without truly understanding why the ball did what it did. Strikers had developed intuition about how to make a ball curve, but that intuition was operating in the dark. They couldn't articulate the relationship between spin and speed and distance. They just knew that if you hit it a certain way, it would curve a certain amount.

Then Carlos made it visible.

What happened after was instructive. Within a few years, every serious free kick taker started studying the Magnus effect. Sports scientists began measuring spin rates with new technology. Training programs started including tutorials on precisely where to strike the ball, how much curve you could generate at different velocities, how wind affected the trajectory. The gap between top tier free kick takers and everyone else widened because now you could *understand* the phenomenon you were trying to exploit.

Science doesn't change physics. It just brings the invisible into focus.

That free kick lived in the gap between intuitive mastery and conscious understanding. Carlos had mastered the Magnus effect through pure repetition and feel. But once everyone else saw it work that clearly, you couldn't claim ignorance anymore. You had to reckon with what was actually happening in the air.

In some sense, that's what every great demonstration does. It takes something that was operating beneath the surface of our attention and makes it unavoidable. The double slit experiment did that for quantum mechanics. The Michelson Morley experiment did it for the aether. A free kick did it for aerodynamics, and most of the world never even realized they were watching physics.

The next time you watch a free kick curve perfectly into goal, understand that you're watching the Magnus effect in action. You're watching air pressure differentials, Bernoulli principles, and rotational velocity align perfectly. You're watching physics become soccer.

And somewhere, a physicist is probably jealous that a football player got to make it look more beautiful than any equation ever could.

So, The Odyssey. Lol. It’s good, maybe Nolan’s best, and not even slightly “woke.” The right-wing hysteria is amazingly detached from reality.

It’s a relentlessly masculine film, visually similar to Troy (2004) at times, but starker and bleaker, less flamboyant and less feminist. Circe, Calypso, Charybdis etc. are classic Nolan female chaos dragons. Penelope’s weaving is not dwelled upon.

The costumes look good. The soundscape is relentless roaring and clanging that rings in your ears when you wander out of the theater feeling slightly overwhelmed by three hours of torchlit Mycenaean brutality.

The brief presence of several black actors and one transsexual feels utterly natural in a mythological setting of seafaring travelers, and the fits of neurosis over it are extremely embarrassing for champions of the Master Race, whose ideological fanaticism and general hostility to aesthetic values has now exceeded the wildest excesses of left-wing media critique.
