Large Hadron Collider..(Pah!)

It's very hard to justify this cost of these things - there is no justification at all.

My father, who sadly died in his mid 50s some 35 years ago , was a nuclear physicist specialising in metallurgy at Harwell - then the Atomic Energy Research Establishment, south of Oxford.  I can recall him saying that these kinds of tools set out to redefine our understanding of the basic building blocks of physics and that means everything around us - and ourselves at an atomic particle level.  That eternal question we start off with as children 'but why?'.

Sometimes the human race makes enormous leaps in the use of technology because our understanding of something is suddenly massively enhanced.   Back when I was a lad in the 1960s I can remember going into Harwell on an open day and seeing a laser for the first time - they were demonstrating using one to cut a steel plate.  The truth was that it was literally a 'solution looking for a problem' which at the time was all it was - a techno novelty.

Roll forward 20 years or so and the compact disc (CD) appeared, CD's are read using a laser beam - our understanding had evolved.

Why doesn’t the laser beam cut the plastic compact disc?

Different lasers do Different things .

Lasers were once the stuff of boys magazines,  these days you can buy one from pound land.

Science is pretty amazing ( although I don't understand most of it ) . Just look at genetics and the understanding of DNA.

They still can't fully explain people from Norfolk though!!

Apparently @ditchman is donating his body to medical science to help - it is already pickled so saves halve the job 😁

You'd think they'd be easy to explain,  as they all have the same DNA 😁.

Pickled ginger 😄.
