AI Trends In 2022: What’s Real And What’s Hype? Hear From The Experts

The end of the year is a time not just for predictions of top trends but also to watch for the biggest hype and most misleading recommendations that get dished out to business leaders. There’s no scarcity of these in the artificial intelligence (AI) space.

As AI evolves, its influence on humanity continues to rise. People often focus on AI’s ability to automate and amplify tasks but underestimate its more profound impact on society. “Very few human creations have had the kind of impact as AI,” says Loomis. He compares it with the invention of language—a “tool” that has changed the trajectory of humans and helped birth civilizations. Today, we are still taking baby steps with AI. However, unlike early humans, we are waking up to the fact that AI is not just a tool but will weave deeper into our society.

“I hope 2022 will be the start of this realization, where we don’t just create new technical practices for AI but also understand how it shapes us. This should alert us to the fact that this is the time to lay the guardrails—the checks and balances needed to guide this change into something greater and not dystopian,” concludes Loomis.

James Webb Space Telescope launch date, time, and how to watch NASA’s livestream

Here’s what you need to know.

The James Webb Space Telescope (JWST, or Webb for short) is scheduled to launch on December 24, 2021, at 7:20 Eastern Standard Time.

It will blast off from French Guiana aboard an Ariane 5 ECA rocket, headed for an orbit around the second Lagrange point, or L2, where the gravitational pull of Earth is equal to the gravitational pull of the Sun.

Webb’s launch has to be carefully timed to put the telescope on the right path. It needs to leave Earth when our planet’s axis is tilted in the right direction, and when the launch site is pointed toward the right area of space. In other words, the James Webb Space Telescope launch has to happen during the right season and at the right time of day. On launch day, those requirements allow just a 30-minute window in which Webb will have to launch — or it will have to wait for another day.

NASA’s Webb Space Telescope Confirmed for December 24 Launch

The James Webb Space Telescope is confirmed for the target launch date of December 24, at 7:20 a.m. EST.

Late on December 17, teams at the launch site successfully completed encapsulation of the observatory inside the Ariane 5 rocket that will launch it to space. Webb’s final launch readiness review will be held on Tuesday, December 21 and, if successful, roll-out is planned for Wednesday, December 22.

Two-time interpretation of quantum mechanics

We suggest an interpretation of quantum mechanics, inspired by the ideas of Aharonov et al. of a time-symmetric description of quantum theory. We show that a special final boundary condition for the Universe, may be consistently defined as to determine single classical-like measurement outcomes, thus solving the “measurement problem”. No other deviation is made from standard quantum mechanics, and the resulting theory is deterministic (in a two-time sense) and local. Quantum mechanical probabilities are recovered in general, but are eliminated from the description of any single measurement. We call this the Two-time interpretation of quantum mechanics. We analyze ideal measurements, showing how the quantum superposition is, in effect, dynamically reduced to a single classical state via a “two-time decoherence” process.

This Asteroid May Be the Shard of a Dead Protoplanet—and Have More Metal Than All the Reserves on Earth

It’s often said Earth’s resources are finite. This is true enough. But shift your gaze skyward for a moment. Up there, amid the stars, lurks an invisible bonanza of epic proportions.

Many of the materials upon which modern civilization is built exist in far greater amounts throughout the rest of the solar system. Earth, after all, was formed from the same cosmic cloud as all the other planets, comets, and asteroids—and it hardly cornered the market when it comes to the valuable materials we use to make smartphone batteries or raise skyscrapers.

A recent study puts it in perspective.

Earth’s resources are finite, but shift your gaze skyward for a moment. Up there, amid the stars, lurks an invisible bonanza of epic proportions.

The Right Stuff

Astronauts have one of the most competitive jobs in the world — 18,300 people applied to be part of NASA’s 2017 class of astronauts, and only 12 made the final cut. But the process of finding astronauts with “the right stuff” has changed over time, and a lot of us Earthlings have the wrong idea about what NASA is looking for.

“I think a lot of the public conception is that we choose super-geniuses or super-jocks or super-pilots,” says Mike Barratt, a NASA astronaut and physician. “I would say that the astronaut office right now is full of people who are comfortable to be with. I mean, don’t get me wrong — we’ve got a couple of super-geniuses, but the main [goal] is that we’ve chosen well-rounded, well-behaved, professional people who are adaptable and resilient, and just someone you could see exploring a brand new world or locking yourself in a garage with for six months.”

NASA’s Juno Spacecraft “Hears” Jupiter’s Moon Ganymede — Listen to the Dramatic Flyby of the Icy Orb

Jupiter mission’s Ganymede flyby offers a dramatic ride-along. It is one of the highlights mission scientists shared in a briefing at American Geophysical Union Fall Meeting.

Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth’s oceans and atmospheres were discussed during a briefing today on NASA.
