“Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena.” ArtPhilosophySeemsForceNaturalPrinciplesSubjectsDesignOffersDifficultyResistanceMathematicalRelateAttractiveGravityFluidManualsForces Of NatureImpulsiveLevity Book:Newton's Principia: The Mathematical Principles of Natural Philosophy Source: Newton's Principia: The Mathematical Principles of Natural Philosophy

“There is a part of yourself that is not subject to change, it is the silent witness behind the scenes. That is essentially your spirit, the spirit being an abstract but real force. It is as real as gravity. It is as real as time. It is incomprehensible. It is mysterious but it is powerful and it is eternal.” RealSpiritForcePowerfulBehindsSubjectsSceneEternalSilentMysteriousWitnessAbstractGravityBehind The Scenes Author:Deepak Chopra
