We need senators who have studied physics and representatives who understand ecology.
Vera RubinRead
In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That's probably a good number for the ratio of our ignorance-to-knowledge. We're out of kindergarten, but only in about third grade.
Interpretation
The quote emphasizes the vastness of what we don't know compared to what we do, likening our understanding of the universe to early education.
Vera Rubin compares the balance of dark and light matter in a spiral galaxy to our own understanding of knowledge and ignorance. She suggests that although we have made significant progress in learning about the universe, we are still at a very basic level of comprehension, much like students in third grade, highlighting the vast gaps in our knowledge and the importance of continuing to learn.
In practice
In a classroom discussion about the limits of human knowledge.
We need senators who have studied physics and representatives who understand ecology.
Nobody ever told us all matter radiated. We just assumed it did.
There was just nothing as interesting in my life as watching the stars every night.
I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.
I had the usual friends who pointed out constellations of stars. But it really was watching the stars. It was getting some sense of the motion of the earth. I found it a remarkable thing.
I think the question is, are there women and have there been women who want to do science and could be doing great science, but they never really got the opportunity?
At the simplest level, economics can better show us the consequences of our actions. Less simple are cases in which we don't have the knowledge to predict the full consequences. Global warming and climate change are examples.
In science, you really do need to have a purpose-driven life. You will succeed to the extent that you get the most out of your career so that you can give the most back. Try to be an addict, driven to achieve discoveries, learning new things, and then writing about them.
Whether you can go back in time is held in the grip of the law of quantum gravity.
We have genuflected before the god of science only to find that it has given us the atomic bomb, producing fears and anxieties that science can never mitigate.
The total quantity of all the forces capable of work in the whole universe remains eternal and unchanged throughout all their changes. All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it.
I always felt that a scientist owes the world only one thing, and that is the truth as he sees it. If the truth contradicts deeply held beliefs, that is too bad. Tact and diplomacy are fine in international relations, in politics, perhaps even in business; in science only one thing matters, and that is the facts.
