“the force required to accelerate a mass of one gram at a rate of one centimetre per second squared”

Probably why a lot of aerospace companies used it in their name.

> The name is reminiscent of several real high-tech companies, including the Gyrodyne Company of America, Teledyne and Teradyne, all of which were founded a few years before Pynchon wrote The Crying of Lot 49, and Rocketdyne, an aerospace company that manufactured, among other things, propulsion systems.

> The "dyne" is the standard unit of force in the centimetre–gram–second (CGS) system of units, derived from the Greek word dynamis, meaning "power" or "force".

I think it’s short for “dynamic” given the vintage of the names, like ”ola” was popular in the early decades of the 20th century, hence “Shinola” shoeshine or “Motorola” car radios.

It is also a non-SI unit, but that might be too obscure — or might motivate nerds like the teledyne founders!

“Weyland” is because they wanted to use Leyland-Toyota but we’re sure they’d be sued, so they changed the first letter. I don’t how “Toyota” became “Yutani”.

The resulting name is better than Leyland-Toyota anyway.

Ha! I've always thought of Tessier-Ashpool every time I saw "Thyssen Krupp" brand on some piece of machinery. Eventually I found out that Krupp supported Nazi regime and used slave labor. Guess they have a fitting name for evil corporation with members of the clan behind it convicted as a criminals against humanity?
