I stumbled upon this great little archive of Albert Einstein talking and writing. There’s some interesting stuff in there mostly reflecting on him as a person and a thinker, in particular in relation to his sense of social justice, rather than a scientist.
One aspect I found interesting was listening to how his English accent improved over time. In the earlier recordings he’s extremely articulate but his accent is very pronounced.
Here’s a portion of one of his papers that I particularly like:
I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise; such notions are for the fears or absurd egoism of feeble souls. Enough for me the mystery of the eternity of life, and the inkling of the marvelous structure of reality, together with the single-hearted endeavour to comprehend a portion, be it never so tiny, of the reason that manifests itself in nature.
