Hopefully, small diameter leads like Riata ST Optim and Durata are up to the challenge and will do well.

Again this study poses the provocative question: is it possible to produce a small diameter lead that is durable.

This finding raises the question: can a small diameter lead be sufficiently robust to perform reliably over years of biologic exposure and mechanical stress in the human body?

With skyscrapers, the deep foundation systems overcome this issue by drilling or hammering in a series of relatively small foundation piers (3ft or 1m in diameter or so).

The 1.8m (60-inch) diameter telescope on Haleakala will also spot many small, faint bodies in the outer Solar System that hid from previous surveys.

The camera portal is considerably wider in diameter, too, still flanked by a small microphone opening but now joined by a third opening: an LED flash.

Besides having unusual optical properties and being very small each is just one-twentieth of a millimetre in diameter the lenses have another trick of particular relevance to micro-optical systems.

Since the rate at which small drops sweep one another up to form large drops varies with the square of their diameter, such drops are too tiny to make rain.
