Technically, Orthogonal means composed of or relating to right angles. It was chosen to name the company because, mathematically, it refers to vectors "at right angles" that have no impact on each other, and the company would thus operate in various mutually independent "core competencies" -- that was the idea, anyway.

I thought everybody knew this.

However; after having to explain it more than once (per day, at times), I have come to realize that some people might be happy to have the meaning of the name illuminated.
