As simple as possible, but not any simpler! Science and tech
Physicists say that they might have solved a long standing problem: How do supermassive black holes manage to merge to larger ones. Their idea: dark matter gets the job done. Or does it? I've had a look.
Nuclear power is promising, but some experts have raised concerns about the fuel that many newly planned nuclear power plants will be using. What are small modular reactors? What is this fuel known as HALEU? Is it really a cause for concern? Let’s have a look.
Physicists recently published a new paper saying that tachyons, particles that move faster than the speed of light, can exist after all. Is this just more hype over nothing, or is this science fiction becoming reality? What do these tachyons have to do with wormholes and warp-drives? Let’s have a look.
This video comes with a quiz which you can take here: quizwithit.com/start_thequiz/1722233290908x8699508…
The company Wavja claims to have developed a new method of converting sunlight into electricity that is much more efficient than currently existing solar cells. Are their claims too good to be true? What’s up with their strange spheres? I've had a look, and here is what I think.
Heat pumps are supposed to reduce the carbon footprint from housing, yet they are surprisingly controversial. One the one hand you hear people say that they are just not getting warm enough to heat anything but the newest houses, on the other hand you have the green brigade claiming heat pumps are God's gift and they will save us all. I had a look at some of those claims.
We’ve all heard how artificial intelligence will supposedly bring giant boosts in productivity, take our jobs, and end humanity, but some business insiders think that AI isn’t going to have remotely as big of an impact as others have said. Indeed, they are worried that billions of dollars will go to waste.
Several universities in the United States have launched research programs on the spread of misinformation on social media. They’ve been repeatedly sued by organizations on the political right who argue that what some scientists call misinformation isn’t misinformation at all. I have the summary for you.
The International Thermonuclear Experimental Reactor, ITER for short, was supposed to be the world’s first nuclear fusion machine to generate net energy. But just last week, the project’s leadership announced another delay and another price hike. Is it still worth the money? And what does this mean for the future of nuclear fusion power? Let’s have a look.
A new cold fusion claim was made by the Indian company HYLENR. I had a look -- and I have some comments.
Plasma has become super trendy recently, with applications across a range of industries. From plasma scalpels to space thrusters diaper bins, what’s up with all that? Let’s have a look what this is all about.
As simple as possible, but not any simpler! Science and technology updates and summaries. No hype, no spin, no tip-toeing around inconvenient truths. News each Wednesday, new topical video each Saturday.
