That's a very good question, I believe in the case of telescopes it's to offer them at a cheaper price.

Good to know this as I use a bog standard very basic focuser and do it manually.

Tried to keep them as near as possible but not exactly the same no. I still think the differences can be shown comparatively though.

Very true mate. Fortunately, I have a very clear sky and maybe 300 plus days when it's crystal clear. It is a rabbit hole I was warned but didn't listen!

This looks like a huge step forward. Researchers from DeepMind and UCL used AI to find a more accurate 'density functional,' solving a problem that has challenged chemists for decades. The AI didn't just find a black-box solu

As with most technology there is both a potential for harm and a potential for the positive. Knowledge can be incredibly dangerous in the wrong hands but we can't exactly unlearn things.

This is a non-invasive approach from researchers at the University of Texas at Austin that uses fMRI scans and a language model to reconstruct the 'gist' of what a person is hearing or thinking. It doesn't get a word-for-word
