A great deal of my work is just playing with equations and seeing what they give.
Interpretation
The exploration of equations can lead to significant discoveries in science.
Paul Dirac expresses the importance of experimentation and play in scientific work. He suggests that engaging with mathematical equations, even in a playful manner, can yield unexpected and valuable insights, highlighting how creativity and curiosity are essential in the pursuit of knowledge.
In practice
In a lecture on scientific methodology, you might say, 'As Paul Dirac wisely noted, much of scientific discovery comes from just playing with equations.'
The research worker, in his efforts to express the fundamental laws of Nature in mathematical form, should strive mainly for mathematical beauty. He should take simplicity into consideration in a subordinate way to beauty ... It often happens that the requirements of simplicity and beauty are the same, but where they clash, the latter must take precedence.
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe.
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
It is quite clear that beauty does depend on one's culture and upbringing for certain kinds of beauty, pictures, literature, poetry and so on...But mathematical beauty is of a rather different kind. I should say perhaps it is of a completely different kind and transcends these personal factors. It is the same in all countries and at all periods of time.
It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress.
[Bacteria] have an incredibly complicated chemical lexicon that ... allows bacteria to be multicellular. In the spirit of TED they're doing things together because it makes a difference.
The universe has really never made things in ones. The Earth is special and everything else is different? No, weβve got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, itβs one of a hundred billion galaxies. And the universe - maybe itβs countless other universes.
I ... began my career as a wireless amateur. After 43 years in radio, I do not mind confessing that I am still an amateur. Despite many great achievements in the science of radio and electronics, what we know today is far less than what we have still to learn.
I was the most emotional of the flight directors. Space really got me all honked up.
The enemy of science is not religion... . The true enemy is the substitution of thought, reflection, and curiosity with dogma.
The real achievement in discoveries... is seeing an analogy where no one saw one before... The essence of discovery is that unlikely marriage of cabbages and kings β of previously unrelated frames of reference or universes of discourse β whose union will solve the previously insoluble problem.
