Last year I made a video about trans athletes, which some of you may remember. This didn't have much to do with my interest in trans people, but more with my difficulty understanding the relevance of competitive sports. I think in the next century or so it'll go out of fashion because any remaining gains will come down to the qu...

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 seve...
Tomorrow we'll talk about a topic I've meant to look at for a long time, space-based solar power. A lot has happened in this field in the past year, it's amazing. It looks like several nations will actually pull through with it! What are we to make of this? On Saturday I go through the pros and cons.

I believe there’s intelligent life on other planets. And the most plausible reason why they haven’t contacted us is that we’re too boring. I mean, we haven’t even figured out how to send information faster than light. Pathetic.
But wait, let me guess. You’ve heard that it’s i...
2023-04-08 12:00:02 +0000 UTC View PostIf you've been following my channel for a long time, you may remember that I few years ago I made a video about faster-than-light travel. I was trying to explain why the arguments saying it's impossible are wrong but I think no one really understood this. So I'm giving it a second try this weekend.

I recently learned there’s a new trend on social media: monk mode. First time I heard of this, I thought it means you pull a hood over your face and start brewing beer in the basement, but not so. Monk mode, it turns out, means cutting out distractions and going into self-isolation to beco...
2023-04-01 12:00:08 +0000 UTC View PostI 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? An...

Nuclear fusion is hot, both literally and financially. Nuclear fusion startups have attracted billions of dollars in the past years. And each of them thinks they’ll be the first to make it work.
The promise is no doubt huge and has attracted supporters such as Bill Gates, Jeff Bezos,...
2023-03-18 13:00:03 +0000 UTC View PostOn Saturday we'll survey different nuclear fusion startups. What are the different approaches, how far along are they, and what are the pros and cons.
