5 Memorable Quotes:

• “That attitude must mean the school didn’t train you to embrace curiosity. That learning was a chore, and now the chores are over.”
• “The government doesn’t always have the best people. But if you hire some of the best people to do whatever it is they want, and their calculations happen to relate to a military project, there you have a two-way street in progress.”
• “The people who think about the universe and study the universe are hugely creative, and the creative energies cannot be pre-scribed. You can’t go to a create… I don’t know that you’ll get their maximum creativity. Say, ‘I need you to invent a cure for cancer right now. Use that brilliance.’ I’ll try, but the greatest discoveries, the greatest cures, the greatest of these, comes from a cross-pollination of interest that people have, that where they were engaged because they were interested just for the sake of being interested.”
• “We know the physiological limits of your ability to know what’s going on around you. Right. And then people say, ‘I have a sixth sense.’ Fine. But as a scientist, I have dozens of senses. Right. Okay? I can measure things that your five senses can’t. I can measure the magnetic field around you, the electromagnetic field. How much microwaves are coursing through your body now? We have no sensors for this. I can see arrows. Fine. I can say other things that are affecting your body now. I can tell you if ionizing radiation is passing through you. I have Geiger counters that can do that. You can’t. Oh, you’ll finally you’ll eventually learn whether you’re exposed to ionizing radiation because you’re you’ll get cancer of your organs and your limbs fall off.”
• “You want you want you could trim that off the dollar and pay for any of them. Pay for so my point is most of the people who say don’t spend it here, spend it there. They think NASA has more budget than it actually does.”
