“O que sabemos é uma gota, o que ignoramos é um oceano.”
Em 1687, Explicando a sua Terceira Lei de Newton - Ação e Reação
Isaac Newton foi um astrônomo, alquimista, filósofo natural, teólogo e cientista inglês, mais reconhecido como físico e matemático.
Sua obra, Princípios Matemáticos da Filosofia Natural é considerada uma das mais influentes na história da ciência. Publicada em 1687, esta obra descreve a lei da gravitação universal e as três leis de Newton, que fundamentaram a mecânica clássica. Ao demonstrar a consistência que havia entre o sistema por si idealizado e as leis de Kepler do movimento dos planetas, foi o primeiro a demonstrar que os movimentos de objetos, tanto na Terra como em outros corpos celestes, são governados pelo mesmo conjunto de leis naturais. O poder unificador e profético de suas leis era centrado na revolução científica, no avanço do heliocentrismo e na difundida noção de que a investigação racional pode revelar o funcionamento mais intrínseco da natureza.
Newton construiu o primeiro telescópio refletor operacional e desenvolveu a teoria das cores baseada na observação que um prisma decompõe a luz branca em várias cores do espectro visível. Ele também formulou uma lei empírica de resfriamento e estudou a velocidade do som. Além de seu trabalho em cálculo infinitesimal, como matemático Newton contribuiu para o estudo das séries de potências, generalizou o teorema binomial para expoentes não inteiros, e desenvolveu o método de Newton para a aproximação das raízes de uma função, além de muitas outras contribuições importantes. Newton também dedicou muito de seu tempo ao estudo da alquimia e da cronologia bíblica, mas a maior parte de seu trabalho nessas áreas permaneceu não publicada até muito tempo depois de sua morte.
Em uma pesquisa promovida pela Royal Society, Newton foi considerado o cientista que causou maior impacto na história da ciência.
De personalidade sóbria, fechada e solitária, para ele a função da ciência era descobrir leis universais e enunciá-las de forma precisa e racional.

I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

Contexto: This most beautiful System of the Sun, Planets and Comets, could only proceed from the counsel and dominion of an intelligent and powerful being. And if the fixed Stars are the centers of other like systems, these being form'd by the like wise counsel, must be all subject to the dominion of One; especially, since the light of the fixed Stars is of the same nature with the light of the Sun, and from every system light passes into all the other systems. And lest the systems of the fixed Stars should, by their gravity, fall on each other mutually, he hath placed those Systems at immense distances one from another.

“If I have seen further than others, it is by standing upon the shoulders of giants.”
Letter to Robert Hooke (15 February 1676) [dated as 5 February 1675 using the Julian calendar with March 25th rather than January 1st as New Years Day, equivalent to 15 February 1676 by Gregorian reckonings.] A facsimile of the original is online at The digital Library https://digitallibrary.hsp.org/index.php/Detail/objects/9792. The quotation is 7-8 lines up from the bottom of the first page. The phrase is most famous as an expression of Newton's but he was using a metaphor which in its earliest known form was attributed to Bernard of Chartres by John of Salisbury: Bernard of Chartres used to say that we [the Moderns] are like dwarves perched on the shoulders of giants [the Ancients], and thus we are able to see more and farther than the latter. And this is not at all because of the acuteness of our sight or the stature of our body, but because we are carried aloft and elevated by the magnitude of the giants. Modernized variants: If I have seen further it is by standing on the shoulders of giants. If I have seen further it is only by standing on the shoulders of giants.
Variante: If I have seen further it is by standing on ye sholders of Giants.
