Global warming GOOD for biodiversity, say boffins

Good for biodiversity maybe but bad for the world as we know it. I suppose though there would be more giant bugs and such once the temp goes up

Schoolteachers can't teach our kids to code, say engineers

Doomed to Fail

This can never work. Here's why. If I were a school teacher, and I learned how to write code, I would immediately quit being a school teacher and get a job writing code. I don't know how it is in the UK though.

Stars say relativity still works

You can tell distant stars by how dim they appear. But don't different size stars put out different amounts of light? Yes, but they also put out different wavelengths of light too. Biggers stars put out more light, but they are a lot hotter and throw off shorter wavelengths. Don't worry about the red giants. Anywy, you can tell how much light they should be putting out by looking at the wavelength. Then by compairing that to the amount of light you actually see, you can tell the distance. At least, that's how I think its done.

You know, my best guess is that so much is known about galaxies, you can probably tell the mass to within a couple percent just by observing one. I wonder if they included dark matter in their calculations. Probably did.
