LK99 -- A new room temperature superconductor?

Today we’ll talk about the new superconductor claim, bad news for new physics, a quantum radar, how to print origami, space-based solar power for a moon station, a dire prediction for the collapse of an ocean circulation, Europe’s first hyperloop test, why NASA shoots lasers at the rain forest, and of course, the telephone will ring.

How to spot and avoid greenwashing

Many companies try to appear environmentally friendly without making a real difference, a strategy that’s been dubbed “greenwashing”. So, is calling a product or service “eco-friendly” just a ploy of companies to get more money out of us? What are the consequences for climate change? And how can we spot those fake claims? That’s what we’ll talk about today.

Einstein was right, again!

Today we’ll talk about Einstein, who was right again, metals that heal, a new type of stellar object, a quantum drum, how conscious awareness comes about, maybe, a better way to tell apart alien signals from boring human signals, a hot spot on the moon, illegal trade of hazardous chemicals, and of course, the telephone will ring.

Electric Vehicles: How difficult will the transition be?

As several of you have pointed out, our recent video on electric vehicles contained several mistakes and omissions. Though now that I think about it, I'm not sure something can contain an omission. In any case, I decided to take it down and here is the revised version.

How scientific are personality tests?

Have you ever taken a personality test? I certainly did. Recently I began wondering what they actually tell me. Is there science behind those tests? Or are they just better horoscopes? In this video, I'll tell you what I've found.

Quantum mechanics is nonlocal, but what does that mean?

Last year, the Nobel Prize in physics was awarded to three physicists who allegedly found that the universe is not locally real. But what does this mean? What are the two types of non-locality? And what did Einstein's have to do with it? That's what we'll talk about today.

Do we need IQ tests for AI?

Artificial Intelligence continues to be the talk of the town, but how intelligent are they really? Come to think of it, what do we mean by "intelligence" anyway? In this video we'll look at IQ tests for humans and for computers and see how current AIs have scored.
