in 2018 the kg will be defined by planck039s constant not a hunk of metaltry a free book from audible for 30 days http:ve42coaudiblespecial thanks to the staff at nist who made this possible: darine haddad jon pratt stephan schlamminger and ben steinadditional footage and animations by sean kelley jennifer lauren lee and frank seiferti have been obsessed with measurement for a long time and i039m not sure quite how it happened the world039s roundest object played a role in this i guess i039m just fascinated by how difficult it is to pin down a quantity like a kilogram a physical object seemed like a good idea until the mass of the international prototype kilogram wasn039t as constant as expected these methods of the kibble balance and silicon sphere have shown better precision than 20 parts per billion making them superior to the old method the agreement between avogadro approaches special thanks to patreon supporters:tony fadell donal botkin jeff straathof zach m

em-sense: touch recognition of uninstrumented electrical and electromechanical objects
Bookmarked 536 weeks ago
most everyday electrical and electromechanical objects emit small amounts of electromagnetic em noise during regular operation when a user makes physical contact with such an object this em signal propagates through the user owing to the conductivity of the human body by modifying a small low-cost software-defined radio we can detect and classify these signals in real-time enabling robust on-touch object detection unlike prior work our approach requires no instrumentation of objects or the environment our sensor is self-contained and can be worn unobtrusively on the body we call our technique em-sense and built a proof-of-concept smartwatch implementation our studies show that discrimination between dozens of objects is feasible independent of wearer time and local environment

hydrodynamic levitation
Bookmarked 451 weeks ago
on a stream of water you can levitate light balls of all sizes and even disks and cylinders the mechanism is not the bernoulli effectwant to make this at home: my friend blake from innovinci emailed me with a cool idea for a video and footage of levitating balls in water streams initially it was tough to explain the physics of what was going on the standard bernoulli effect relies on the object being completely immersed in the upward-flowing fluid but in this case the water seems to form a single stream around the object and it039s deflected away and down from the stream by newton039s third law the force on the water by the ball is equal and opposite to the force of the water back on the ball pushing it up into the stream there is a stable equilibrium position because if the ball moves into the stream it quotcuts offquot the water going over the ball so it drifts out if it drifts out too far then lots of water passes over the ball pushing it back into the streamspecial thanks to
