But the "point" of science is to cure the disease, understand how the plants grow, understand how atoms behave, how chemicals react, etc, etc.
The author was clearly going for some kind of romantic, quotable, end thought, but I think it's clear he's no Hawking when it comes to that.
This may be a linguistic thing, though. Perhaps we read that phrase in a different way. But to me, it very much echoes "it's about the journey, not the destination".
Going back to your point about "do you care about how they disproved it?" Yes, I do, and you should too. The michaelson morley experiment was a properly performed scientific experiment with every step documented so someone could replucate it. It is a source of truth which I can trust. On the otherhand if a tom dick and harry claimed that they had a vision and that this vision told them relativity is not true, I would definitely not trust such a claim.
Your point about the result being important is valid. Yes, as an engineer or as a business man results are far more important than process. But a scientist, must care about the process more than the result. If they didnt we would not be able to trust their conclusions.
> The point of science is not the holy grail but the quest
If the quest is the point, you can do that anywhere, anytime, without regard of the outcome. The point is a glimpse of the truth. How we get there is largely irrelevant.
