“... there is no shame in not knowing. The problem arises when irrational thought and attendant behavior fill the vacuum left by ignorance.”

“When you visit countries that don't nurture these kinds of ambitions, you can feel th absence of hope...people are reduced to worrying only about that day's shelter or the next day's meal. It's a shame, even a tragedy, how many people do not get to think about the future. Technology coupled with wise leadership not only solves these problems but enables dreams of tomorow.”

“When your reasons for believing something are justified ad hoc, you are left susceptible to further discoveries undermining the rationale for that belief.”

“God is an ever-receding pocket of scientific ignorance.”

“Where ignorance lurks, so too do the frontiers of discovery and imagination”

“Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of kids. They outnumber kids. They vote. They wield resources. That's why my public focus is primarily adults.”

“... informed ignorance provides the natural state of mind for research scientists at the ever-shifting frontiers of knowledge. People who believe themselves ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the cosmos.”
