When lots of energy hits an atom, it can knock off electrons, making the atom extremely chemically reactive and initiating further destruction. Thatâs why radiation is so dangerous.
Quasiparticlesâexcitations that behave collectively like particlesâare central to energy applications but can be difficult to detect.
In the Stone, Bronze and Iron Ages, the state of the art of materials science defined technologyâs zenith and accelerated economies.
