A linear back-and-forth motion from purely rotational motion. This... is the Tusi couple, a geometric mechanism introduced by the Iranian scholar Nasir Tusi in the 13th century. 🎥 marmarjoonshow more

This video looks like a rotating wheel. But watch... just one single sphere. It never rotates. Every ball only moves in a perfectly straight line back and forth. This is simple harmonic motion where linear position follows: x = R cos(ωt) By perfectly offsetting the timing of each straight path, the collective motion creates the illusion of rotation.show more

THE “ISLAMIC GOLDEN AGE” IS A LIE. PERSIAN SCIENCE... BUILT CIVILIZATION. The so-called Islamic Golden Age was Iranian genius under foreign occupation. Islam produced no science. It only used the names of Persian masters while suppressing free thought. AVICENNA (IBN SINA) — Iranian. Wrote the medical encyclopedia Europe studied for centuries. AL-KHWARIZMI — Iranian. Created algebra and algorithms. RAZI — Iranian. Separated smallpox from measles and advanced chemistry. NASIR AL-DIN TUSI — Iranian. Invented the Tusi-couple later used by Copernicus. OMAR KHAYYAM — Iranian. Solved cubic equations and built one of history’s most accurate calendars. These were Persian minds. Not Arab. Not Islamic. Islam has no science of its own. It only stole, renamed, and later tried to erase the Iranian source. Share this and fight the Arabic Islamic colonization…show more

The Economic Freedom Fighters Johannesburg caucus submitted a Motion:... Removal of registered indigent beneficiaries from the city of Johannesburg debtor's list. Motion was approved by council. The EFF is always on the side of the poor. The DA and FFplus rejected the motion and must be remembered as antipoor parties and anti worker.show more

SpatialTracker Tracking Any 2D Pixels in 3D Space Recovering... dense and long-range pixel motion in videos is a challenging problem. Part of the difficulty arises from the 3D-to-2D projection process, leading to occlusions and discontinuities in the 2D motion domain.show more

THE MOTION IS CRAZY. THE GREATEST SCHOOL TOUR IS... BACK. WENT TO AMERICA AND CAME BACK TO ABJ CITY. THIS ONE IS FOR THE KIDS. #MOTIONSICKNESSshow more

Our feature artist/tutorial today is this great ANIMATION TUTORIAL... on FABRIC, by the talented Mazu (Commissions Closed)! That note on OFFSETTING the duplicate motion is a brilliantly simple way to create a sense of ORGANIC VARIATION in the motion. #animation #gamedev #2danimation #manga #animeshow more

With the Dragon Boat Festival approaching, this slow-motion footage... captures a dragon boat race in Shunde, Guangdong. A living tradition that showcases cultural heritage, teamwork in perfect sync, and the elegance of Chinese aesthetics in motion.show more

A classic linear zoetrope uses static images on a... wall, which appear animated as a train passes. The motion creates an illusion of movement, with the frame spacing and train speed determining the animation’s frame rateshow more

What Looks Like A Complex Set Of Spinning Parts... Is The Core Of How Trucks Convert Engine Power Into Motion. A drivetrain system transfers torque from the engine through the transmission, driveshaft, and differential to the wheels. Each component plays a specific role. The transmission adjusts torque and speed, the driveshaft carries rotational force, and the differential distributes power between wheels while allowing them to rotate at different speeds during turns. Seeing the system in motion reveals how precisely synchronized these components must be to handle heavy loads and maintain efficiency under stress. In Heavy Vehicles, Power Is Only Useful When It Is Controlled.show more
