“When you can measure what you are speaking about, and express it in nu...” — Lord Kelvin Quote

“When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarely, in your thoughts advanced to the stage of science.”

“Large increases in cost with questionable increases in performance can be tolerated only in race horses and women.”

“Heavier-than-air flying machines are impossible.”

“The atheistic idea is so nonsensical that I cannot put it into words.”

“Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.”

“The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.”

“The stars, they are as the sun. Each star. Every star. And those spheres- they are worlds, realms, each one different yet the same.”

“The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, is as good as dead, and his eyes are dimmed (Albert Einstein)”

“The ADHD brain is built for responsiveness, for novelty, for meaningful stimulation. It is attuned to cues of interest and urgency, rather than arbitrary deadlines or routines.”

“Another glorious feature of many modern science museums is a movie theater showing IMAX or OMNIMAX films. In some cases the screen is ten stories tall and wraps around you. The Smithsonian's National Air & Space Museu, the popular museum on Earth, has premiered in its Langley Theater some of the best of these films. 'To Fly' brings a catch to my throat even after five or six viewings. I've seen religious leaders of many denominations witness 'Blue Planet' and be converted on the spot to the need to protect the Earth's environment”

“All my life, I'd been accustomed to thinking of life as things that moved: rabbits, dogs, fish, other people. Life that mattered had been life like me, life that breathed and bled, life that ate and slept. I'd been aware of that other layer of life, of the still but living things that supported it all, but I'd thought of it as the lower layer, as the less important stratum of life. Empty prairie was for plowing or grazing; land that was too poor for farming or cattle was wasteland. I'd never lived near a forest like this, but when I'd come to one, I'd understood why it existed. The trees were to be taken for lumber. The land had to be cleared to become useful. The idea that forest or prairie or even wasteland should be left as it was had never occurred to me. What good was land until it was tamed? What good was a piece of earth that did not grow wheat or fruit or grass for cattle? The value of every bit of land I'd ever trodden, I'd reckoned in terms of how it could benefit a man. Now I saw it with the eyes of a forest mage. Here life balanced as it had for hundreds, perhaps thousands of years. Sunlight and water were all that was required for the trees to grow. The trees made the food that fed not only whatever moving creatures might venture through this territory, but also became the food that replenished the soil when their leaves fell to rot back into earth. This working system was as refined and precise as any piece of clockwork ever engineered by man. It worked perfectly.”
