23 Items of vital vocabulary for 2023

23 items of vital vocabulary you’ll need to know in 2023(six of them for today)

Passkeys? Post-quantum cryptography? Vertiports? Get up to speed here. Excerpts from the Economist Nov. 14th 2022

"Here are our best 23 guesses, with a definition of each one, to expand your vocabulary for the coming year":

"Green, blue and brown hydrogen"

"Green” hydrogen is made using renewable energy to split water into hydrogen and oxygen via electrolysis. By contrast, making “black” or “brown” hydrogen involves burning coal or lignite"

"eSIM"

"So-called esim technology replaces physical chips with digital codes that can be zapped from an old handset to a new one."

"Post-quantum cryptography"

"Quantum computers exploit the weirdness of the subatomic realm to do things that ordinary computers cannot"

"new “post-quantum” cryptography standards, designed to be invulnerable even to quantum computers, were approved in 2022,"

"Mixed reality"

"Mixed reality (xr or mr) goes a step further by allowing real and virtual items to interact. For example, you might play a game of table tennis in which the paddles are real, but the ball is computer generated"

"Passkeys"

"Essentially, instead of typing a password, you use a token, stored on your phone or computer and protected by a fingerprint or facial recognition, to log into apps or websites"

"Horizontal and vertical escalation"

"Horizontal escalation is where the geographical scope of a conflict expands" "Vertical escalation is where the intensity of the conflict increases"
