Can The Metaverse Fix Our Generosity Crisis?
A disturbing documentary titled Childhood 2.
Spoiler alert: Itâs worse than you could imagine.
Returning to Childhood 2.0 and so many discouragingâokayâdepressing documentaries from the past few years (The Great Hack, Requiem for The American Dream, The Social Dilemma, etc.), itâs tempting to throw up our hands. To surrender to disillusionment. Even nihilism.
Thatâs the wrong way to view the difficulties of our times.
Instead, letâs use our challenges as mechanisms for growth. Or as Winston Churchill once remarked, âNever let a good crisis go to waste.â In the spirit of innovation and goodwill to humankind this holiday season, letâs seize this challenging moment to tell a new story about philanthropy.

Three Things AI Machines Wonât Be Able to Achieve
In this bonus interview for the series Science Uprising, computer scientist and AI expert Selmer Bringsjord provides a wide-ranging discussion of artificial intelligence (AI) and its capabilities. Bringsjord addresses three features humans possess that AI machines wonât be able to duplicate in his view: consciousness, cognition, and genuine creativity.
Selmer Bringsjord is a Professor of Cognitive Science and Computer Science at Rensselaer Polytechnic Institute and Director of the Rensselaer AI and Reasoning Laboratory. He and his colleagues have developed the âLovelace Testâ to evaluate whether machine intelligence has resulted in mind or consciousness.

Our Universe Trailer: Morgan Freeman Narrates The History Of Everything
When you need someone to narrate the history of the universe â and Mel Brooks is busy â you might as well go with Morgan Freeman. Not only has Freeman played God in âBruce Almightyâ and âEvan Almighty,â but heâs also told âThe Story of Godâ and âThe Story of Usâ for National Geographic.
In âOur Universe,â Freeman is lending his voice to a new six-part nature documentary series for Netflix. As the title implies, this series is even bigger in scope than âThe Story of Us.â Itâs looking back at the whole history of the universe and how 13.8 billion years have led us to this moment.
Freeman also narrated the Oscar-winning documentary âMarch of the Penguins,â and while Iâm not a wildlife expert, I think you might spot some brown penguins in the âOur Universeâ trailer. For anyone who enjoyed seeing cosmic events recreated with special effects in Terrence Malickâs âVoyage of Time,â but wished the movie had been narrated by Detective Somerset instead of Detective Mills (as in, Freeman and Brad Pittâs âSevenâ characters), this Netflix series might be right up your alley. Check out the trailer for âOur Universeâ below.
How I Learned to Stop Worrying and Love Uncertainty
Like most physicists, I spent much of my career ignoring the majority of quantum mechanics. I was taught the theory in graduate school and applied the mechanics here and there when an interesting problem required it ⊠and thatâs about it.
Despite its fearsome reputation, the mathematics of quantum theory is actually rather straightforward. Once you get used to the ins and outs, itâs simpler to solve a wide variety of problems in quantum mechanics than it is in, say, general relativity. And that ease of computationâand the confidence that goes along with wielding the theoryâmask most of the deeper issues that hide below the surface.
Deeper issues like the fact that quantum mechanics doesnât make any sense. Yes, itâs one of the most successful (if not the most successful) theories in all of science. And yes, a typical high school education will give you all the mathematical tools you need to introduce yourself to its inner workings. And yes, for over a century we have failed to come up with an alternative theory of the subatomic universe. Those are all true statements, and yet: Quantum mechanics doesnât make any sense.
Attractive female students no longer earned higher grades when classes moved online during COVID-19
New psychology findings suggest that attractive students earn higher grades in school, but for female students, this beauty premium disappears when classes are taught remotely. The findings were published in the journal Economic Letters.
A large body of research suggests that physical appearance has an impact on a personâs success. For example, attractive people tend to earn more money and report higher life satisfaction than less attractive people. Interestingly, scholars have yet to agree on the explanation behind this beauty premium.
One account suggests that the beauty advantage can be explained by discrimination. For example, employers may inherently favor attractive over unattractive workers. Another perspective suggests that beauty is a productivity-enhancing attribute. This view suggests that attractiveness lends itself to higher productivity, for example, through increased self-confidence.
