Because you can get extremely interesting answers, like the excellent answer to the question "What is Chirped Pulse Amplification, and why is it important enough to warrant a Nobel Prize?" on Physics Stack Exchange:
The 2018 Nobel Prize in Physics has just been announced, with half going to Arthur Ashkin for his work on optical tweezers and half going to Gérard Mourou and Donna Strickland for developing a technique called "Chirped Pulse Amplification". While normally the Wikipedia page is a reasonable place to turn to, in this case it's pretty flat and not particularly informative. So:
- What is Chirped Pulse Amplification? What is the core of the method that really makes it tick?
- What pre-existing problems did its introduction solve?
- What technologies does it enable, and what research fields have become possible because of it?
I am not a physicist and just know the usual school physics, but have no problem understanding the answer. Excellent!
