Cat on the mat

I again found something pretty interesting at my internship.

It's actually an explanation about analog inputs, and I found it really creative. I don't know whether you'll think that way too, but here you go:

While a digital input can tell us about discrete changes in the physical world, such as whether the cat is on the mat, or the cat is off the mat, there are times when this is not enough. Sometimes we want to know how fat the cat on the mat is. In order to know this, we’d need to be able to measure the force the cat exerts on the mat as a variable quantity. When we want to measure variably changing conditions like this, we need analog inputs.

Hehehe...that certainly made me chuckle.

By the way I went to a barbecue at Phoebe's place this afternoon, but I think I shall write about it tomorrow... simply 'cos I'm feeling kinda lazy :P
