Physicists trap electrons in a 3D crystal for the first time

Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump

MIT physicists have trapped electrons in a pure crystal, marking the first achievement of an electronic flat band in a three-dimensional material. The rare electronic state is thanks to a special cubic arrangement of atoms that resembles the Japanese art of “kagome.” The results provide a new way for scientists to explore rare electronic states in 3D materials.

New laser setup probes metamaterial structures with ultrafast pulses

Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precise

The technique, developed by MIT engineers, probes metamaterials with a system of two lasers — one to quickly zap a structure and the other to measure the ways in which it vibrates in response, much like striking a bell with a mallet and recording its reverb. In contrast to a mallet, the lasers make no physical contact. Yet they can produce vibrations throughout a metamaterial’s tiny beams and struts, as if the structure were being physically struck, stretched, or sheared.

YEAAAAAAHHHHH

self-flagellation and self-bullying are all bad motivators for change BTW. it can be hard to escape from a spiral but genuinely u have to be nice to urself or nothing will change

School depends on obedience. Learning depends on curiosity. School kills curiosity.
