Throughout this volume, we have felt considerable inconvenience, from the dogmatical classification of plants, and have all along been floundering between species and variety, which certainly under culture soften into each other.

Patrick Matthew

Added to this we already see numerous indications of a future, in which the chemical and mechanical laws of nature will be more intimately united. In short, the natural laws of chemistry, as well as those of mechanics, are laws of Reason, and both are so intimately connected, that they must be viewed as a unity of Reason.

Hans Christian Ørsted

Approximavit sidera He brought the stars closer

Joseph von Fraunhofer

It should ever be borne in mind that the primary object of every study ought to be an inward one that of enlarging and elevating the intellect; and the direct aim of science should be the discovery of the principles of unity, order, and connexion, which are everywhere manifest in the universal life of nature.

The first thoughts, which gave rise to his Principia, he had, when he retired from Cambridge in 1666 on account of the plague. As he sat alone in a garden, he fell into a speculation on the power of gravity; that as this power is not found sensibly diminished at the remotest distance from the centre of the earth to which we can rise, neither at the tops of the loftiest buildings, nor even on the summits of the highest mountains, it appeared to him reasonable to conclude that this power must extend much further than was usually thought: why not as high as the moon? said he to himself.
