Immortality has gone secular. Unhooked from the realm of gods and angels, it’s now the subject of serious investment – both intellectual and financial – by philosophers, scientists and the Silicon Valley set.
Researchers have developed a new technique that peppers metallic nanoparticles into semiconductors, an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices.
It’s the first technique that can inexpensively grow metal nanoparticles both on and below the surface of semiconductors.
The process adds virtually no cost during manufacturing and its improved efficiency could allow manufacturers to use fewer semiconductors in finished products, making them less expensive.
This video is about the phenomenon of neutrino oscillations, which is where neutrinos can change flavors (ie, change between electron, muon, or tau neutrinos) because those interaction states are in non-trivial superpositions of the free traveling/mass eigenstates (𝜈1, 𝜈2 and 𝜈3).
