I have choose Stephen Hawking as the person who give a lots of contributions on our universe nowadays.Since he was a children he just a normal person who enjoy to play with other children and he coxed with rowing team.But during his degree level,he was attacked by motor neuron disease that makes him lost of his ability to make a movement or to speak.The way that make me proud with him he can proved that handicap not a obstacle for someone to achieve a successful.His spirit in himself makes him be recognized nowadays in entire world.He also always thinking far away about future and thus he makes a whole research about universe.Thats all.
