For the record: Quantum mechanics does not deny the existence of objective reality. Nor does it imply that mere thoughts can change external events. Effects still require causes, so if you want to change the universe, you need to act on it.
Interpretation
This quote emphasizes the importance of action in the physical universe, countering misconceptions about quantum mechanics affecting reality through thought alone.
Lawrence M. Krauss addresses a common misunderstanding of quantum mechanics, emphasizing that while the theory has profound implications for our understanding of reality, it does not support the idea that simply thinking can alter external circumstances. Instead, he asserts that change in the universe necessitates tangible actions grounded in the causal relationships that govern physical laws.
In practice
In a scientific seminar discussing the philosophy of quantum physics.
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.
Creationists eagerly seek a gap in present-day knowledge or understanding. If an apparent gap is found, it is assumed that God, by default, must fill it.
When the problem [quantum chromodynamics] is finally solved, it will all be by imagination. Then there will be some big thing about the great way it was done. But it's simple -it will all be by imagination, and persistence.
There's branches of science which I don't understand; for example, physics. It could be said, I suppose, that I have faith that physicists understand it better than I do.
Philosophy of science is about as useful to scientists as ornithology is to birds.
The way life manages information involves a logical structure that differs fundamentally from mere complex chemistry. Therefore chemistry alone will not explain life's origin, any more than a study of silicon, copper and plastic will explain how a computer can execute a program.
The dimmed outlines of phenomenal things all merge into one another unless we put on the focusing-glass of theory, and screw it up sometimes to one pitch of definition and sometimes to another, so as to see down into different depths through the great millstone of the world.
