Video description See inside Lawrence Livermore National Laboratory’s National Ignition Facility where on Dec. 5, 2022, the first controlled fusion experiment in history achieved fusion ignition: also known as scientific energy breakeven, the experiment produced more energy from fusion than the laser energy used to drive it, achieving a major scientific breakthrough decades in the […]
Memory Wire Experiments
Video description This video from Andy Elliott Craft & Creations demonstrates some interesting experiments with shape memory metals while explaining the science behind them.
Scientists create world’s smallest record
Video description Scientists in Denmark have created the world’s smallest “vinyl” record, which is so tiny that it can barely be seen by the naked human eye. Measuring just 15 x 15 mm, with grooves of a depth of just 65 nm, the tiny record plays 25 seconds of Rockin’ Around the Christmas Tree in […]
Engineers develop a new kind of shape-memory material
Massachusetts Institute of Technology, Boston, MA, has announced the discovery of a new category of shape-memory materials that could open up a new range of applications, especially for high-temperature settings, such as actuators inside a jet engine or a deep borehole. Shape-memory metals have long been used as simple actuators in a variety of devices […]
The answer to why Roman concrete is so durable
Researchers have spent decades trying to figure out the secret of Rome’s ultradurable ancient construction material, used in the famed Pantheon as well as aqueducts and seawalls that endured especially harsh environmental conditions. Now, a team of investigators from MIT, Harvard University, and laboratories in Italy and Switzerland, has made progress in this field, discovering […]
