"Science is what you know, philosophy is what you don't know."
"Human psychology is the most mysterious thing in the world."
"The Man in the Moon is in fact a record of ancient catastrophes--most of which took place before humans, before mammals, and probably even before life arose on Earth. It is a characteristic conceit of our species to put a human face on random cosmic violence."
"The electrical, electronics and wireless radio frequency (RF) industries are creating an increasingly high radiation environment for the human. This is comparable to the elevated radiation environment found at high altitudes and smart health researchers would be wise to contrast high altitude diseases to the epidemics of our time, such as Autism, Attention Deficit Disorder (ADD), Fibromyalgia, Electromagnetic Hypersensitivity (EHS), and so on."
"Some say we are not like humans but we are more like them than we are different. Man and animals are in the same species as mammals as they have mammary glands that produce the milk to nurse their young. Their lungs breathe air and their blood is warm. They are vertebrates in that their skeletal system and well-designed spines hold their bodies together. Each cell is made of molecules, each molecule is made of atoms, and each atom is made of protons, neutrons and mostly electrons, which are made of waves of fibered light."
"Is it not curious, that so vast a being as the whale should see the world through so small an eye, and hear the thunder through an ear which is smaller than a hare's? But if his eyes were broad as the lens of Herschel's great telescope; and his ears capacious as the porches of cathedrals; would that make him any longer of sight, or sharper of hearing? Not at all.-Why then do you try to 'enlarge' your mind? Subtilize it."
"Science is properly more scrupulous than dogma. Dogma gives a charter to mistake, but the very breath of science is a contest with mistake, and must keep the conscience alive."
"Our probable ancestors, Homo erectus and Homo habilis -now extinct- are classified as of the same genus (Homo) but of different species, although no one (at least lately) has attempted the appropriate experiments to see if crosses of them with us would produce fertile offspring."

"You've done it in the simulator so many times, you don't have a real sense of being excited when the flight is going on. You're excited before, but as soon as the liftoff occurs, you are busy doing what you have to do."
"You may not have any extra talent, but maybe you are just paying more attention to what you are doing."
"So everything turned out fine, and we were given the opportunity to go to Washington and be briefed on the project of man in space, and given the opportunity to choose whether we wanted to get involved or not."
"The excitement really didn't start to build until the trailer - which was carrying me, with a space suit with ventilation and all that sort of stuff - pulled up to the launch pad."
"We worked with the engineers in the design and construction and testing phases in those various areas, then we would get back together at the end of the week and brief each other as to what had gone on."
"You have to be there not for the fame and glory and recognition and being a page in a history book, but you have to be there because you believe your talent and ability can be applied effectively to operation of the spacecraft."
"It's a very sobering feeling to be up in space and realize that one's safety factor was determined by the lowest bidder on a government contract."
"We also knew it would be difficult, because of the financial condition of the family, for me to go to college."
"Then there was the challenge to keep doing better and better, to fly the best test flight that anybody had ever flown. That led to my being recognized as one of the more experienced test pilots, and that led to the astronaut business."
"The rocket had worked perfectly, and all I had to do was survive the reentry forces. You do it all, in a flight like that, in a rather short period of time, just 16 minutes as a matter of fact."
