This chart is from the original he published - just the five data points. Pretty simple huh? The “observation, originally made in 1965, that the number of transistors on an integrated circuit would continue to double every year. Although this increase has slowed to a doubling in eighteen to twenty four months, Moore’s law has held true for nearly fifty years and is the foundation for the astounding Information Technology revolution we see around us.”

For those interested in Moore’s law, remarkably, I think the best information is my Dad’s book, The Computing Universe, which is also the source of the quote.

Moore’s Law

The time to a target depends on the ratio of distance to the target over it’s size. So clicking on a small target close by might take a similar time to clicking on a large target further away. It’s a simple model and there are a few little games out there to bring it home in practice.

I’m reminded however, of an observation from a mentor of mine, Darrell Mann, that just because people call it a law doesn’t mean you have to treat it like one. The example of Apple’s standard program icons at the base of the screen that expand when you mouse near them, are a simple technique that help to overcome the limitations of Fitt’s law. There are plenty more. Don’t be sucked in to laziness by a name.

Ghoti is a constructed word intended to illustrate some of the craziness in English punctuation, in that, taking the sounds of its parts from different places, it could be said as fish.

In my book -ough, in particular, is the craziest as in enough, thorough, bough, through, although - all pronounced totally differently.

I’d heard it credited to George Bernard Shaw but, apparently, his biography credits it to an ‘anonymous spelling reformer’.
