Lawrence M. Krauss Quotes

A physicist, an engineer and a psychologist are called in as consultants to a dairy farm whose production has been below par. Each is given time to inspect the details of the operation before making a report.The first to be called is the engineer, who states: "The size of the stalls for the cattle should be decreased. Efficiency could be improved if the cows were more closely packed, with a net allotment of 275 cubic feet per cow. Also, the diameter of the milking tubes should be increased by 4 percent to allow for a greater average flow rate during the milking periods."The next to report is the psychologist, who proposes:"The inside of the barn should be painted green. This is a more mellow color than brown and should help induce greater milk flow. Also, more trees should be planted in the fields to add diversity to the scenery for the cattle during grazing, to reduce boredom."Finally, the physicist is called upon. He asks for a blackboard and then draws a circle. He begins: "Assume the cow is a sphere....

I've told you two things : First, you're much more insignificant than you ever imagined and second, the future is miserable. But you should be happy, because we may live in a universe without purpose but that means the purpose in our lives is the purpose we create. And we should consider ourselves fortunate to have evolved in this place in the middle of nowhere and evolved a consciousness so we can understand the universe from the earliest moments of the big bang to the far future. So instead of being depressed, you should enjoy your brief moment in the sun.

The saddest thing about these imagined deathbed conversions is that, even if they were real, they could hardly be seen as victories for Christ. They are stories in which the final pain of a fatal disease, or the fear of imminent death and eternal punishment, is identified as the factor necessary for otherwise rational people to believe in the supernatural.If mental torture is required to effect a conversion, what does that say about the reliability of the fundamental premises of Christianity to begin with? Evangelicals would be better advised to concentrate on converting the living. Converting the deceased suggests only that they can't convince those who can argue back. They should let the dead rest in peace.

A universe without purpose should neither depress us nor suggest that our lives are purposeless. Through an awe-inspiring cosmic history we find ourselves on this remote planet in a remote corner of the universe, endowed with intelligence and self-awareness. We should not despair, but should humbly rejoice in making the most of these gifts, and celebrate our brief moment in the sun.

If the universe doesn't care about us and if we're an accident in a remote corner of the universe, in some sense it makes us more precious. The meaning in our lives is provided by us; we provide our own meaning.

More often than you might think, teaching science is inseparable from teaching doubt.

The one thing that I want every single child to have experienced at some point in their life, as part of their education, is to have some idea they hold to be true, and at the very basis of their being, proved to be wrong.Because that opens your mind to the realization that the world is different than you thought it would be, and you have to begin to open your mind to the possibilities of existence.And opening your mind frees you, it doesn't constrain you. It makes the world more wonderful, more exciting, and more worth living in.

[I]n science we have to be particularly cautious about 'why' questions. When we ask, 'Why?' we usually mean 'How?' If we can answer the latter, that generally suffices for our purposes. For example, we might ask: 'Why is the Earth 93 million miles from the Sun?' but what we really probably mean is, 'How is the Earth 93 million miles from the Sun?' That is, we are interested in what physical processes led to the Earth ending up in its present position. 'Why' implicitly suggests purpose, and when we try to understand the solar system in scientific terms, we do not generally ascribe purpose to it.
