An expedition up Mount Kilimanjaro scientifically measures how water's boiling point decreases with altitude, offering a tangible demonstration of atmospheric pressure's impact and highlighting the challenges of high-altitude physiology.
Veteran astronaut Don Pettit and his mentee Matthew Dominick share insights on astrophotography and life aboard the ISS from the iconic Cupola. They discuss camera gear, capturing Earth's beauty, and the challenges of orbital mechanics.
Explore the intricate mechanics and historical significance of antique single, double, and triple-barrel "duck foot" pistols from the 19th century. Discover the evolution of firearm technology and the challenges of firing these historical weapons.
Destin demonstrates a backwards-driving tractor, revealing how learned neural pathways from the backwards bicycle allow for instant operation. This highlights the brain's neuroplasticity and the surprising cognitive skills of drone pilots.
Explore EBR-1, the world's first nuclear power plant in Idaho, which pioneered electricity generation using controlled nuclear fission and the breeding of plutonium. Discover the science behind this historic achievement and its impact on modern energy.
Mysterious flashes observed during high-speed impacts may be caused by the rapid compression and ignition of gases, rather than just material fracture. Experiments with projectiles and specialized tests reveal the surprising role of trapped air.
An experiment to manufacture a grill scrubber in the USA reveals the immense challenges and critical importance of rebuilding domestic manufacturing capabilities, from sourcing components to the vital tool and die industry.
Nuclear plant workers are emphasizing the stringent safety protocols and minimal radiation exposure they experience daily. Advanced training and adherence to the ALARA principle, focusing on shielding, distance, and time, ensure worker safety against radiation and contamination.
A visit to Pompeii reveals the Roman Empire's incredible engineering feats, from advanced road systems to gravity-fed water networks. However, the preserved city also exposes the harsh realities of exploitation and the enduring complexities of human nature.
Thousands of oval depressions across the eastern US, known as Carolina Bays, have long puzzled scientists. New research suggests strong winds and water erosion during the last Ice Age, rather than meteor impacts, sculpted these unique landscapes, which are now vital habitats for species like the Venus flytrap.
