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?
Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.
There's no doubt that scientific training helps many authors to write better science fiction. And yet, several of the very best were English majors who could not parse a differential equation to save their lives.
As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.
Now, radical forward thinking is offering hope for the future: Replacement body parts to order. A team of scientists in California believe that if you can design them on a computer, you should be able to print them out.
The earth also is spherical, since it presses upon its center from every direction.
I'm proud of the fact that I thought of the solar wind. It was an exercise in pursuing curiosity, which is the main motivation for studying physics from a personal standpoint.
