If there is a small rocket on top of a big one, and if the big one is jettisoned and the small one is ignited, then their speeds are added. Hermann Oberth
Modern designs of iceboats are very efficient, utilizing aerodynamic designs and low friction, and can achieve speeds as high as ten times the wind speed in good conditions.
Or in other works I have also projected the sound in a cube of loudspeakers. The sound can move vertically and diagonally at all speeds around the public. Karlheinz Stockhausen
There comes a point in your life when you realize how quickly time goes by, and how quickly it has gone. Then it really speeds up exponentially. With that, I think you start to put a lot of things into context; you start to see how huge the world is, and really, the universe. Michael Keaton
Thus I was able to make pioneering measurements of the height and physical scale of plasma clouds in the ionosphere and also to estimate wind speeds in this region. Antony Hewish
But at the end of the year, only urban areas currently have access to the signal and even then, an early large-scale test of the network indicated that less than half of Manchester city centre could use its high speeds. According to the study, outside the city centre there was no 4G coverage at all.
