Hi all, I'm currently studying Physics with Astronomy and Space Science in my final year. I've decided not to go for the Honors degree so I will be graduating with a general one in a few months. I'm sorry to admit that I didn't enjoy studying this (although I love the astronomy side of it...

I have read that many tea masters insist that when infusing a tea that requires less-than-boiling water, you should first let the water reach a full 100 degrees C and let it cool back down to the target temperature, rather than take it off the burner as it is approaching boiling. I think it was...
