Nature’s toughest fiber can make bulletproof vests, future sutures, and even be engineered to come out of goat milk. Now a Japanese researcher has gone one step further, using spider silk for art. Specifically, a set of violin strings, which apparently have a “soft and profound timbre.”
Why are we able to produce a tone when we rub our finger around the lip of a crystal glass?
The atoms in a crystal glass are arranged in a very regular pattern, a structure resembling a honeycomb or a chain-link fence. In contrast, the atoms in normal glass are connected irregularly, more like the veg-etables in vegetable soup. The pattern of the atoms in crystal ensures that the glass vibrates in only one way, with one single frequency.
