The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.
Interpretation
The quote reflects on the challenges and philosophical implications of understanding gravity through quantum mechanics.
Richard P. Feynman's quote highlights the profound uncertainties and philosophical questions that arise from the weak observational effects of quantum gravity. He suggests that perhaps nature itself is indicating a need to reconsider our approaches and assumptions about quantizing gravity, urging us to think critically about the fundamental principles of physics.
In practice
During a physics lecture, to introduce the complexities of quantum mechanics.
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.
The rights of neutrality will only be respected when they are defended by an adequate power. A nation, despicable by its weakness, forfeits even the privilege of being neutral.
Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.
The opposite of every truth is just as true.
For it is with the mysteries of our religion, as with wholesome pills for the sick, which swallowed whole, have the virtue to cure; but chewed, are for the most part cast up again without effect.
Antiracists must acknowledge that patriarchy has long been a weapon of racism and cannot sit comfortably in any politic of racial transformation.
And if your head explodes with dark forebodings too _x000D_ I'll see you on the dark side of the moon.
