: Can anyone tell me where the saying "T minus" comes from (when used with a coundown), and what exactly it means?
The 'T' stands for 'Time' and means that there is a certain period of time (which will be specified)left before whatever it is that is supposed to happen happens (a rocket launch or whatever.)
For example, T minus 20 seconds means there are 20 seconds to go before the launch.
