iFAQ: Miscellany

What is an iFAQ?

An iFAQ is not a new Apple product, instead it is something that takes little bit of effort to create (fine, hate me for it). An iFAQ is a collection of infrequently asked questions, because, let's be honest, most questions in other FAQs are never asked by anyone. Some of the questions featured in these were first published in a magazine I used to edit, then later in a blog I edited. Hopefully they won't be republished again. All of them were written by me or a direct associate anyway so I don't think it necessary to make to much of it. In short, the aim of an iFAQ is to provide answers to questions that are seldom asked, but deserve to earn recognition.

How does a turbocharger work?

Turbochargers work by pressurising air entering an engine and adding more fuel to combust it, so that you can get more torque from fewer cylinders. Superchargers are probably different, but as Jeremy Clarkson puts it: "with a supercharger, air goes in, witchcraft happens and you go faster". In reality, superchargers are less sophisticated versions of turbochargers where the pump to increase pressure is mechanically driven, thus taking horsepower from the engine. Some very large superchargers can use more than a hundred horsepower from the engine to keep them running. Superchargers therefore aid top speed, while turbochargers aid acceleration. Turbochargers are more efficient because they utilise exhaust gases, rather than power from the engine.

What is the lowest point in Microsoft Excel?
