Americans swept away the instruments of English hereditary inequality - entails and titles of nobility - even before we had a constitution.
It was one time when people thought the value of the fine structure constant was important. Now of course it's still important, of course, as a practical matter,but we now know that the value it has is a function, that in any fundamental theory you derive the fine structure constant as a function of all sorts of mass ratios and so on and it's not really that fundamental.
Interpretation
What this quote means
The fine structure constant, once seen as paramount, is now understood to be derived from deeper principles in physics.
Steven Weinberg's quote highlights the evolution of our understanding of fundamental constants in physics, specifically the fine structure constant. Initially regarded as a key value, ongoing research has revealed that its significance is more nuanced; it is not an intrinsic feature of nature but rather a derived quantity influenced by various mass ratios and theoretical frameworks. This reflects the complex interplay between empirical observation and theoretical interpretation in the quest for a deeper understanding of the universe.

[Science] is corrosive of religious belief, and it's a good thing too.
With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.
I'm offended by the kind of smarmy religiosity that's all around us, perhaps more in America than in Europe, and not really that harmful because it's not really that intense or even that serious, but just... you know after a while you get tired of hearing clergymen giving the invocation at various public celebrations and you feel, haven't we outgrown all this? Do we have to listen to this?
How strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like?

Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number - there are only methods to produce random numbers, and a strict arithmetic procedure of course is not such a method.

The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
The ideas which led to the Analytical Engine occurred in a manner wholly independent of any that were connected with the Difference Engine. These ideas are indeed, in their own intrinsic nature, independent of the latter engine and might equally have occurred had it never existed nor even been thought of at all.
'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes its multitude of changes, this number doesn't change. That is, if you calculate again, this quantity, it'll be the same as it was before. An example is the conservation of energy: there's a quantity that you can calculate according to a certain rule, and it comes out the same answer after, no matter what happens, happens.
