Wow! What a beautiful definition - 'the natural angle of repose of a granular substance' - so poetic. This snippet of information will allow me to smile to myself tomorrow, as I am sure that, 'not a lot of people know that!'. I wonder how long it will be now before it comes up in a crossword or a quiz? Do you find that new bits of knowledge are often called upon frequently after first learning? I particularly like this one because it connects my maths/science background with my love of words.

Thankyou! b.c.
