gravity

Dave Jones of EEVblog demonstrates that a frequency counter can detect gravity through the 2g tipover effect on quartz crystal oscillators. He shows the reading shift as the instrument's orientation changes.

Intrinsic Gravity is a real-time demoscene production by Still, made with the Tooll tool for Under Construction 2014. It is a black-and-white op-art animation with a soundtrack by hoffman.

Gravity Industries tests its jet suit for paramedic mountain rescue with the Great North Air Ambulance in the Lake District, reaching a casualty in 90 seconds versus a 25-minute climb.

Quint BUILDs tests a rooftop water storage setup in which solar power pumps water up to the roof and a turbine generates power later. He works through the numbers to show how much energy it actually stores.

A short demo of a walking droplet on a vibrating silicone oil bath passing through a double slit and producing interference, a macro-scale analogue of pilot-wave behavior.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.
