As a physicist, I've always found cosmology to be a rational elixir; it distances me from ordinary concerns.
Interpretation
Cosmology helps the speaker escape from mundane worries by providing a rational perspective.
In this quote, Lawrence M. Krauss expresses how cosmology, the study of the universe and its origins, serves as a source of comfort and clarity. By engaging with the vastness of the cosmos, he finds a way to detach himself from the trivialities of everyday life, gaining a broader perspective that transcends ordinary concerns. This illustrates the transformative power of scientific inquiry, providing not just knowledge but also solace in the face of life's challenges.
In practice
In a lecture on the importance of science during challenging times, this quote can emphasize the value of understanding our place in the universe.
The one experience that I hope every student has at some point in their lives is to have some belief you profoundly, deeply hold, proved to be wrong because that is the most eye-opening experience you can have, and as a scientist, to me, is the most exciting experience I can ever have.
If our species is to survive, our future will probably require outposts beyond our own planet.
The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
I cannot stress often enough that what science is all about is not proving things to be true but proving them to be false.
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis.
We must alter theory to adapt it to nature, but not nature to adapt it to theory.β
Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life.
Science can amuse and fascinate us all, but it is engineering that changes the world.
Even the facts of science may dust the mind by their dryness, unless they are ... rendered fertile by the dews of fresh and living truth. Knowledge does not come to us by details, but in flashes of light from heaven.
It is certain that there may be extraordinary mental activity with an extremely small absolute mass of nervous matter: thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head. Under this point of view, the brain of an ant is one of the most marvelous atoms of matter in the world, perhaps more so than the brain of a man.
The scientist who recognizes God knows only the God of Newton. To him the God imagined by Laplace and Comte is wholly inadequate. He feels that God is in nature, that the orderly ways in which nature works are themselves the manifestations of God's will and purpose. Its laws are his orderly way of working.
