Electric Highways: A good idea?

Several European countries have done trials for electric highways , some of which have now been concluded. The results have been unexpectedly controversial. What are electric highways? Why are the results controversial? Could this be the answer to transitioning away from fossil fuels? Let’s have a look.

Musk: Are Quantum Computers even good for Something?

Elon Musk launched an XPRIZE for Quantum Applications! It’s a 3-year, 5 million dollar global contest that’s looking for ways to use quantum computers to solve real-world challenges that benefit society. Doesn't this basically mean quantum computers don’t currently have any good use cases? And what do you need to do to win? Let’s have a look.

Climate Change Slows Rotation of Earth, New Study Finds

Climate change has had some pretty weird consequences - beers are tasting worse, goats are shrinking, and flights are bumpier. Another unexpected outcome is that the rotation of the earth has slowed, making days longer. How does that work? Let’s have a look.

New Superconductor Scandal: What We Know So Far

Last year, Ranga Dias from the University of Rochester in New York claimed he had found a material that was superconducting at room temperature. He has now been accused of research misconduct. This is a summary of what we know so far.

Are wildfires good?

Wildfires have made a lot of headlines recently. Climate change, they say, has made them worse. But some ecologists now say that suppressing wildfires is a bad idea and will just make things worse. You read that right, they say we should just let it burn -- so long as no people are in danger. Does that mean small wildfires are actually good? Let’s have a look.

My first total eclipse: What I am looking forward to

On April 8th, a total solar eclipse will cast its shadow across Mexico, the United States and Canada. This solar eclipse is quite special for a number of reasons. Let’s have a look at why this solar eclipse is so special and some things you should be on the lookout for.

This Self-Heating Concrete Melts Snow – No Power Needed

Material scientists at Drexel University in Philadelphia have developed a self-heating concrete that warms up on its own when temperatures drop below zero. No power needed. How does this new “smart material” work? Will we see it on our streets soon? Let’s have a look.

How I fell out of love with academia

How AI could kill us -- or save us

Artificial intelligence will likely eventually exceed human intelligence, which could turn out to be very dangerous. In this video I have collected how things could go wrong and what the terms that you should know when discussing this topic. And because that got rather depressing, I have added my most optimistic forecast, too. Let’s have a look.

Search for Quantum Foam Begins at South Pole

Physicists will soon begin an experiment at the South Pole to test if space has quantum fluctuations. Their new approach looks for decoherence in neutrinos oscillations that are sensitive to what has been dubbed "quantum foam" that could even contain tiny black holes. If successful, this experiment could uncover something that will combine Einstein’s theory of gravity and quantum physics? Let’s have a look.

CERN's new Ghost experiment could find "hidden" particles

New articles have been popping up about CERN’s new experiment looking for so-called “ghost particles.” What are ghost particles? Is CERN haunted? What is this new experiment? Let’s have a look.

The Hype you Didn’t Notice: The Quantum Internet

Quantum effects could lead to faster computers, more precise measurements, custom-designed materials, and much more. But the quantum internet is a solution in search of a problem. What is Quantum Internet? Can it really go faster than the speed of light? Do we need it to keep data safe? Let’s have a look.

Sulphur as Energy Storage -- Gamechanger?

For decades we have seen scientists and engineers trying to outdo each other in finding more efficient and cheaper ways of storing energy. A group from the German Aerospace Center now says that sulphur is the way forward. Let’s have a look

Quantum Gravity Breaks Causality -- And You Can Compute With It

If you flip a light switch, the light will turn on. A cause and its effect. Simple enough… until quantum gravity come into play. Once you add quantum gravity, lights can turn on and make switches flip. And some physicists think that this could help build better computers. Why does quantum physics make causality so strange? And how can we use quantum gravity to build faster computers? Let’s have a look.

Quantum Cognition: Does it explain irrational decisions?

Humans can sometimes be hard to understand, much like quantum physics - unless you watch this channel regularly of course^^. That’s why a mathematician has come out with an idea of “quantum cognition”. What is this so-called quantum cognition? Does it explain why humans make irrational decisions? Let’s have a look.

20 Years-Old Puzzle (Almost) Solved: The Muon Anomaly

Three years ago, there was a frenzy over an experiment at Fermilab that confirmed anomaly of the muon - a fundamental particle in the standard model. Since then, physicists have debated whether the theory needs to be revised or whether there is something wrong with the calculation. A new paper now says it's neither.

Biggest Ever Quantum Vortex Created for Black Hole Simulation

A cute new experiment at the university of Nottingham has created a "quantum tornado" by which they want to study what quantum effects are going on nearby black holes. Does this make any sense? Let’s have a look.

Should I be terrified of climate change? Should you be terrified?

I have now come across a bunch of articles in which scientists are more or less explicitly advocating that we scare people into action on climate change. To me this is a step from information to manipulation. Let’s have a look.

AI needs a LOT of energy. But that is not its main problem.

Artificial Intelligence consumes a lot of energy, both during training and during operation. We’ve heard a lot about this. Indeed, Sam Altman the CEO of OpenAI recently said that we’ll need small modular nuclear reactors just to power all those AIs. Well, hold that thought. Today I want to look at how much energy these AIs really need and explain why I think this isn’t the main problem.

Who Owns the Clouds? Cloud Seeding May Cause Global Water War

Cloud seeding is a way to make clouds rain before they naturally would. It is becoming increasingly common. Just in the past months, it has been used around the world to combat droughts, clean polluted air, and fight wildfires. But what are the ramifications of controlling the weather? Will this lead to water wars in the future? Let’s have a look.
