Quotable

• Every building is a snapshot of a particular time and place - the raw materials that were on hand, how far the builders' technology had progressed, and the aspirations of its creators.
• The only way forward is to respect people with different points of view.
• The legacy of supernovas is as close as our own bodies. The carbon in our cells, the oxygen in the air, the silicon in rocks and computer chips, the iron in our blood and our machines.
• The iron in our blood comes from supernovas. There's a direct connection between stars and us.
