BUT...ITER is a fun physics experiment and provides much more employment than a solitary fan heater.
It gives also food to many families, and not only to physicists.
but real scientists are kids, and pre-school kids are good scientists.
in fact some try to understand science, and science tragedies like LENR by separating scientist in 3 groupes:
- those looking for power
- those looking for a job
- those looking for fun
The first do politics and I accuse them to be caus eof current scientific catastrophe.
The seconds are good for improvements, but very conservative and slow breakthrough, while supporting groupthink and pathological consensus.
The thirds are doing science sometime if they are rigorous, this mean playing seriously with their expensive toys, and their complex math sudoku, but sometime they are simply in love with their theory forgetting reality, math, and their respective constraints.
all that explains why science if difficult
