"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

I think a lot about what Carl Sagan said in one of his final interviews.

HISTORY OF PHYSICS

Chandrasekhara Venkata Raman and his love for music.

Although he didn't study them exhaustively, Raman discovered that the rich tonal quality of the tambura and veena (shown below) was due to the peculiarity of the bridge.
