Modern Trebuchet Breaks the Sound Barrier with Drum-Driven Power

Tom Stanton’s video showcases a modernized trebuchet that uses a drum-wound rope and a release latch to convert the energy of a dropping weight into rapid arm rotation. Through several tests and redesigns, the launcher achieves speeds from about 528 km/h with a 10 kg weight to around 1,249 km/h with a 40 kg counterweight and a 4 g projectile, including an initial ~0.0025 second release window and notes of component stress—demonstrating a high-speed physics demonstration rather than battlefield practicality.

Examining the Evidence: U.S. Intelligence Clears Israel in Gaza Hospital Blast

A detailed visual analysis by The New York Times casts doubt on the widely cited video evidence that an errant Palestinian rocket caused the deadly explosion at Al-Ahli Arab hospital in Gaza City. The Times concludes that the missile seen in the video actually detonated in the sky roughly two miles away and is unrelated to the hospital blast. The analysis does not determine the cause of the explosion or who is responsible, but it complicates the straightforward narrative put forth by Israeli officials. The death toll and responsibility for the blast remain contested, as both Israeli officials and Palestinian militants blame each other.
