還有人說，這一時間還要早，大約在公元前5000年以前。古埃及的天平雖然做的很粗糙，但是已經有了現代天平的輪廓，成為現代天平的雛型。下圖畫的就是古代埃及人使用的天平。從圖可見，這種天平是用一根豎棍中間鉆個孔，橫穿一根棍兒，在棍的兩端各用繩子掛上一個盤子。這種天平使用了很長時間，直到大約公元前500年，羅“桿稱”才出現，桿稱靠稱砣的位置來保持與被稱物品重量的平衡，實際上是將天平的一端（放砝碼端）由固定式變成活動式，其好處是只要配上一個稱砣就可以了，而天平的砝碼要好幾個。桿稱也是用繩子吊一個盤子，再用繩子吊一個稱砣，除一端可活動外，基本形式與天平相同。人們在使用天平和桿稱中，感到用繩子吊一個盤子是一件很麻煩的事。：NatureandNature'lawlayhidinnight;Godsaid,"LetNewtonbe,"andallwaslight。自然與自然的定律，都隱藏在黑暗之中；說"讓來吧！"于是，一切變為光明。九百多年來，西敏寺除了供信徒作禮拜、祈禱、膜拜之外，也是英國

并進一步進進發展為微分幾何、微分方程、變分法等等，這些又反過來促進了理論物理學的發展。例如瑞士J.伯努利曾征求速降落曲線的解答，這是變分法的初始問題，半年內全歐數學家無人能解答。②分析——綜合。分析是從整體到部分（如微分、原子觀點），綜合是從部分到整體（如積分，也包括天與地的綜合、三條運動定律的建立等）。在《原理》中說過：“在自然科學里，應該像在數學里一樣，在研究困難的事物時，

砝碼或被稱物在處于秤盤前后位置時會引起秤盤盤架和橫梁前后傾側，在處于秤盤左右位置時會引起秤盤盤架的左右傾倒。為克服此缺點，架盤天平采取了中刀、邊刀和加寬刀架的措施，并在結構設計上采用了羅伯威爾（Roberval）機構。在羅伯威爾機構中，桿桿AB、A′B′與縱桿AA′、BB′、支柱EE′鉸鏈連接，組成兩個相等的平行四邊形AA′E′E和EE′B′B。當大小相等的力P、P′分別作用于左右橫臂上時，對支柱來說，即使作用的位置不對稱，也能水平地平衡。無論AB如何傾斜，AA′、BB′都與支柱EE′平行。從EE′的左側來看，當將與縱桿AA′的距離為d的力P作用于橫臂上時，就有一個與P大小相等、方向相同的力作用于A和A′點;同時。說，而這樣一種假說無論是形而上學的還是物理學的，無論屬于隱蔽性質的還是力學性質的，在實驗哲學中都沒有它們的地位。”這些論述奠定了自然哲學的基礎，啟開了實驗科學的大門，300年來為自然科學的繁榮立下了不朽功勛。
