Here’s a great example of engineers over thinking a problem.

When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity.

To combat the problem, NASA scientists spent a decade and billions of dollars to develop a pen that would work.

Their research produced a pen the effectively writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300 Celsius.

The Russians used a pencil.
