Is the bird flu the next pandemic?

This winter we’ve seen a severe outbreak of the bird flu, or avian flu. How much should we worry about that? I’ve tried to figure out what’s going on, and, well, let me just say I’ve learned a lot of really scary things that I don’t want to withhold from you. What’s the bird flu? Is it dangerous to humans? And if so, what can we do? That’s what we’ll talk about today.

Is being trans a social fad among teenagers?

Should transgender teens transition? This rather personal question occupies a prominent place in the American culture war. One the one side you have people claiming that it’s a socially contagious fad among the brainwashed woke who want to mutilate your innocent children. On the other side there are those saying that it’s saving the lives of minorities who’ve been forced to stay in the closet for too long. And then there are normal people, like you and I, who think both sides are crazy and could someone please summarise the facts in simple words, which is what I’m here for.

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.
