Okay I lied a bit, there are actually two quotes there but having the same message.
We human describe nature in classes (physics, biology, chemistry etc). But these are all interconnected elements that obey specific ‘laws’. The wonderful thing about it, is that everything physical in this world can be described by laws, theories and models which are just numbers and mathematics.
God created everything and deliberately makes nature representable to us using mathematics. This is in harmony with the verses in the Holy Quran, such as:
And has subjected to you all that is in the heavens and all that is in the earth; it is all as a favour and kindness from Him. Verily, in it are signs for a people who think deeply (45:13).
The hydrogen atom, somewhere, perhaps at the edge of the universe, would have the same property as the hydrogen on earth (yes, even after factoring all those shifts, spins or whatever quantum state you would so love to discuss). This is the promise and system set by God in his created world. For us to think, ponder and benefit.
Great scientists such as Dirac will continue to come and go. But those with deep and vast understanding, would eventually conclude that the world must have a creator; God All-Mighty, that maintains and sustains this beautiful world, until what is promised by God: The Hour, The Day of Judgment.
There are a lot of things ‘unseen’ (our soul, Heaven, Hell, Angels etc) that we human can never unlock its secrets. Again, this is mentioned in the Quran:
… Nor will Allah disclose to you the secrets of the Ghaib (unseen), … (3:179)
May we find guidance and peace in this life and in the hereafter.
