START AT GO. “Graphene twistronics that rely on the artificial stacking of perfect graphene at mismatched angles of 1.1° have gained a lot of research interests since its discovery in 2018. They are promising for superconducting and quantum computing, but still at the infancy stage in terms of scalable fabrication.” https://link.springer.com/article/10.1557/s43577-021-00135-y View in LinkedIn

SO ENDS this section on the surprising properties of sheets of imperfect graphene stacked at a magic angle to cause moiré interference patterns, and their enormous, and largely untapped applications. Not only are they practical but they are extremely beautiful and very interesting. https://link.springer.com/article/10.1557/s43577-021-00135-y View in LinkedIn

“METAPHYSICS is spiritual, experimental, abstract, mystical, ephemeral, internal, irreplicable, imprecise, selective, other-worldly, impractical, and impossible to prove. Science studies the world of matter while metaphysics seeks to transcend it.”" " https://lnkd.in/eVXZCsiB View in LinkedIn

NEUTRINO OSCILLATIONS. “The T2K Collaboration has been able to study these oscillations with unprecedented precision, and has observed possible evidence of leptonic CP violation.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE EXPERIMENT. “In the T2K experiment, a neutrino beam is generated at the Japan Proton Accelerator Research Complex in Tokai. Here, highly accelerated protons hit a dense graphite target, producing large quantities of particles known as pions and kaons.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE DETECTORS. “These particles decay, giving rise to a neutrino beam (or an antineutrino beam, depending on the conditions used), which is monitored by two detectors 280 metres away.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

MEASUREMENT. “The neutrinos subsequently travel through Earth without being stopped, but some are detected by the underground detector at the Kamioka Observatory 295 km away, deep beneath Japan’s Mount Ikeno. The detector consists of 50,000 tonnes of ultrapure water surrounded by a vast array of light sensors.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE OUTPUT. “When a neutrino interacts with a neutron in the water, it can produce a muon or an electron, depending on its flavour. The T2K experiment detects the muons and electrons and discriminates between them, thereby identifying the flavour of the impinging neutrino and measuring the oscillation probability of muon-to-electron neutrino conversion.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE HOPE. “The results exclude CP conservation (that is, they suggest that CP violation has occurred) at a 95% confidence level, and show that the CP-violating parameter is likely to be large. These results could be the first indications of the origin of the matter–antimatter asymmetry in our Universe.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
