What were Isacc newton's acknowledgements?

Answer 1

I don't think it's an acknowledgement but he discovered gravity when he was sat under an apple tree and he was hit by a falling apple and he wondered why it went down instead of up or down.

Answer 2

Isaac newton acknowledged the contributions of several scientists and thinkers who came before him, such as Galileo, Kepler, and Descartes. He also credited the support and assistance of colleagues and friends like Edmond Halley and John Flamsteed in his work on the laws of motion and the law of universal gravitation.
