“Nothing is impossible; the word itself says ‘I’m possible!” ~ Audrey Hepburn, Actress
Once upon a time, humanity believed that it was impossible to fly, but now we can. Once upon a time, a mathematician dreamed of a crazy idea to build a machine to process data, now we have computers. Once upon a time everyone believed that a four-minute mile was humanly impossible to break, but a pre-med student thought otherwise, and has broken the record, now it’s common practice. We now have broken the sound barrier and now we have gone to the moon and back, and we now have astronauts living above earth in a space station. We now can sample Mars’s soil from earth.
