The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.
Interpretation
The quote highlights the fundamental unity of matter in the universe, showing that everything, including stars and Earth, is composed of the same basic building blocks.
Richard P. Feynman's quote emphasizes a profound realization in the field of astronomy: the elemental composition of stars mirrors that of Earth. This insight not only illustrates the interconnectedness of the universe but also suggests that humans share a deep relationship with the cosmos, made of the same atoms that constitute every form of life on our planet. This commonality invites us to reflect on our place in the universe and the nature of existence itself.
In practice
In a lecture about the universe and our connection to it.
The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?
We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.
The first principle is that you must not fool yourself and you are the easiest person to fool.
It has not yet become obvious to me that there's no real problem. I cannot define the real problem; therefore, I suspect there's no real problem, but I'm not sure there's no real problem.
For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
Scientists surely have a special responsibility. It is their ideas that form the basis of new technology. They should not be indifferent to the fruits of their ideas. They should forgo experiments that are risky or unethical.
I suppose I can live with missing decimals, missing floors to tall buildings, and floors that are named instead of numbered. A more serious problem is the limited capacity of the human mind to grasp the relative magnitudes of large numbers. Counting at the rate of one number per second...to count to a trillion takes 32,000 years, which is as much time as has elapsed since people first drew on cave walls.
Many different planets are many different distances from their host star; we find ourselves at this distance because if we were closer or farther away, the temperature would be hotter or colder, eliminating liquid water, an essential ingredient for our survival.
Every usage, no matter how bizarre or nonstandard, fascinates me, as it tells me something about the way language is evolving.
I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.
Pierre Curie came to see me and showed a simple and sincere sympathy with my student life. Soon he caught the habit of speaking to me of his dream of an existence consecrated entirely to scientific research, and he asked me to share that life.
