In science, there are no universal truths, just views of the world that have yet to be shown to be false.
So if we assume we are not the only civilisation in the galaxy, then at least a few others must have arisen billions of years ahead of us. But where are they?
Heisenberg’s Uncertainty Principle is one of the most misunderstood parts of quantum theory, a doorway through which all sorts of charlatans and purveyors of tripe8 can force their philosophical musings.
One of the great joys of science is to understand something for the first time–to really understand, which is very different from, and far more satisfying than, knowing the facts.
It is undoubtedly true that Galileo didn’t intend to challenge the very theological foundations of the Church of Rome by observing the Moon through a telescope. But scientific discoveries, however innocuous they may seem at first sight, have a way of undermining those who don’t much care for facts. Reality catches up with everyone eventually. With.
Astronomy is what we have now instead of theology. The terrors are less, but the comforts are nil’.
The current worldview is never claimed to be correct, in the very important sense that there are no absolute truths in science. The body of scientific knowledge at any point in history, including now, is simply the collection of theories and views of the world that have not yet been shown to be wrong.
Thoughts, feelings, hopes and dreams exist on Earth because of electrical activity inside a 1.5-kilogram blob of stuff, which hasn’t changed much since the earliest modern humans began the long journey out of Africa.
To me, and to the participants of at the Green Bank conference, the idea that a civilization might destroy itself is both ludicrous and likely. We are pathetically inadequate at long-term planning, idiotically primitive in our destructive urges and pathologically incapable of simply getting along.
Things inexorably get worse.
Science is delighted frustration. It is about asking questions, to which the answers may be unavailable – now, or perhaps ever. It is about noticing regularities, asserting that these regularities must have natural explanations and searching for those explanations.
I believe powerfully that we who have the power should strive to extend the gift of education to everyone. Education is the most important investment a developed society can make, and the most effective way of nurturing a developing one.
You have to get old because of the geometry of spacetime.
The trick as an educated citizen of the twenty-first century is to realise that Nature is far stranger and more wonderful than human imagination, and the only appropriate response to new discoveries is to enjoy one’s inevitable discomfort, take delight in being shown to be wrong and learn something as a result.
The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.
I deliberately borrow from Shakespeare; the most precious objects on Earth are not gems or jewels, but ink marks on paper. No single human brain could conceive of Hamlet, Principia Mathematica or Codex Leicester; they were created by and belong to the entire human race, and the library of wonders continues to grow.
Common sense is completely worthless and irrelevant when trying to understand reality. This is probably why people who like to boast about their common sense tend to rail against the fact that they share a common ancestor with a monkey.
They would certainly have been simpler than the earliest known microbial mats, but somewhere in your genome there will be sequences of DNA that have been faithfully passed down across the great sweep of geological time, and if you have children, you’ll pass these four-billion-year-old messages on to them.
Science is most definitely not a priesthood where people stand on a mountain and pass truths down to the waiting minions below.
One of the beautiful things about mathematical physics is that equations contain stories.
Art cannot be limited by temporal aberations.
