But of his success and if you are and then Trump and nor especially in Silicon Valley what kinds of trades can you learn what kind of tips can you learn by studying the life and the mistakes of the Wizard of Menlo Park So once again our special guest today is Randall Stross the book is called The Wizard of Menlo Park and he s a columnist for The New York Times. The 1st question for you is how did you get interested in writing a biography of this iconic figure Thomas Edison about 10 years ago I wrote a biography of Steve Jobs. I was looking at job is attempt to found a 2nd company after our and he was a big fan of Edison and and of course that doing research for that book I kept running into at a name and then the book The font that which was about Bill Gates of Microsoft again I ran into Mr Edison. I think it s fair to say that anyone working in the high tech industry today. All those a lot out of them. And to many people feel that connection that. That that to be inventors contributi
what is drawn collider. hadrons are a family of subatomic particles that composite particles made up of quarks. are the best known her drawings on neutrons and protons which are found in atomic nuclei that major components in the matter that makes up our bodies and the world around us. physicists use high energy collisions of. drawings to try to answer questions about matter and energy the collisions are carried out in giant particle accelerators. the world s most powerful collider is deep underground at the european organization for nuclear research or cern near geneva switzerland. the large hadron collider l
h c is a twenty seven kilometer long ring of ultra cool magnets surrounding two finn pipes through these particles headed in opposite directions are accelerated to near the speed of light and then slam together in detectors the size of houses. for how. the colliding hadrons form a hot dense fireball which produces a range of different subatomic particles. with such a big bangs in the l h c scientists try to recreate the early stages of the evolution of matter in that sense colliders our time machines the higher the energy at which the particles collide the closer they approach the conditions at the moment of the big bang the origin of our universe. and that s why excel or a terms like the l.h. c. have to undergo upgrades to collide ever more particles at ever higher energies.
