SpaceX's plan to fly you across the globe in 30 minutes  (transcript)
Summary
I was a little disappointed because Elon Musk didn't appear in this TED talk, the story was about SpaceX, though.
I don't know that Elon Musk is the founder, Chief executive officer (CEO), and leads designer of SpaceX and Gwynne Shotwell is President and Chief Operating Officer (COO)at SpaceX.
SpaceX is a private American aerospace manufacturer and space transportation services company.
The goal is reducing space transportation costs 1) and enabling the colonization of Mars 2).
Reducing space transportation costs means not only about fuel and engines but also reusing aircraft and carrying many passengers, so by using the rocket of SpaceX, not only we can go to Mars, we can go around the world in 30 minutes and to China from America in about 10 minutes.
People thought that men were good at math, physical and sciences and space businesses were considered as men's work.
The period is possible to travel by using rockets and to work regardless of the gender.
