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.
What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.
In these days when science is clearly in the saddle and when our knowledge of disease is advancing at a breathless pace, we are apt to forget that not all can ride and that he also serves who waits and who applies what the horseman discovers.
Half of what we know is wrong, the purpose of science is to determine which half.
It felt—nearly twenty-five hundred years after Hippocrates had naively coined the overarching term karkinos—that modern oncology was hardly any more sophisticated in its taxonomy of cancer.
From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where the rules do not work - not the places where they do work! That is the way in which we discover new rules.
Genomics are about individuals. It's about what's specific to you, not your siblings, not your parents - each of us is totally unique. We will only see that uniqueness by drilling down to the genetic code.
