The true cost of nuclear power

Out of the many bad arguments against nuclear power, there are two good arguments: It's too expensive and the power plants take too long to build. But are they true? And if so, why is it that nuclear power is so slow and so costly? That’s what we’ll talk about today.

Nuclear Power Comeback Update: Poland Authorizes Small Modular Reactors

Nuclear power is back in fashion in many countries because of its potential to decarbonize even energy-intense industry quickly. In its latest success, Poland has authorized the construction of 24 small nuclear reactors at six sites across the country.

Complexity: The biggest gap in modern science

Everyone loves to talk about complex problems and complex systems, but no one has any idea what it means. I think that understanding complexity is THE biggest gap in science today. What do we even mean by complexity? What do we know about it? And what’s the problem with trying to explain it? That’s what we’ll talk about in this video.

Black Hole Singularities "Faith, not science!" Prominent Physicist Claims

Science and the law come in to conflict more often than you might think. In this episode I want to tell you about several cases that I have followed which have concerned me greatly.

Is science coming to an end? On the one hand, it seems like scientific progress has slowed to a crawl and no big breakthroughs are happening any more. On the other hand, we are left with many unsolved problems in science that I am pretty sure have a solution. In this video I explain why I think that we need to seriously consider the possibility that we live in the final phase of scientific discovery.

Realistic Expectations for Quantum Computing

Quantum computing has attracted a lot of attention and much of what you read in the headlines is overhyped. But underneath the hype there's real promise. In this video I go through the applications of quantum computing that we can realistically expect -- if they ever get the devices to work...

We Could Beam Solar Energy Down From Space. But Should We?

Solar power is a nice idea. Except for the issue with the clouds. And the nights. So, how about we instead put solar panels up in space and then beam the energy down? This futuristic idea is known as “Space Based Solar Power”. It’s been around since the 1960s, but in recent years several nations have launched projects to make it reality. I think they’re not kidding. Space-Based Solar Power is about to become a real thing. But how is it supposed to work? Is it a good idea to beam energy down from space? What are the pros and cons? That’s what we’ll talk about today.

I think faster than light travel is possible. Here's why.

If you've been following my channel for a really long time, you might remember that some years ago I made a video about whether faster-than-light travel is possible. I was trying to explain why the arguments saying it's impossible are inconclusive and we shouldn't throw out the possibility too quickly, but I'm afraid I didn't make my case very well. This video is a second attempt. Hopefully this time it'll come across more clearly!

Addicted to social media -- Is this even possible?

I recently learned there’s a new trend on social media: monk mode. It means cutting out distractions and going into self-isolation to become more productive. It’s supposedly based on science and particularly concerned with avoiding social media, because that’s addictive. But can social media really be addictive? Does the monk mode work? And what’s the science behind it? In this video, we'll sort it out.

Collective Stupidity

When we come together in groups we can be so much more than the sum of the parts. But sometimes groups are just much more stupid. Collective stupidity is the flipside of collective intelligence, and we see it a lot on social media. Why are groups sometimes collectively stupid and sometimes not? What can we do to be more intelligent in groups? In this video I explain the most important points.

I believe chatbots partly understand what they chat about. Let me explain.

I used to think that today's so-called "artificial intelligences" are actually pretty dumb. But I've recently changed my mind. In this video I want to explain why I think that they do understand some of what they do, if not very much. And since I was already freely speculating, I have added some thoughts about how the situation with AIs is going to develop.

An Air Condition for the Planet: How Could It Work?

All power plants create waste heat that contributes to global warming. At the moment, the contribution is fairly small, but if mankind flourishes it is bound to increase and eventually it will become a problem. The only thing we an do about it is to build an air condition for the planet. Scientists have come up with some ideas how to address the problem that I hope you will find entertaining.
