This is wonderful: computer science pioneer Grace Hopper hands out 11.8 inch nanoseconds.

/via jtotheizzoe:

Grace Hopper, heroine of computer science/rear admiral of awesomeness, defines the length of a nanosecond.

It’s 11.8 inches long. The maximum distance, in a vacuum, that light can travel in a billionth of a second.

Our brains aren’t built to truly fathom the quantum and the nano. But bless the Grace Hoppers for helping us adapt.
