People of substance may sin without being exposed for their stolen pleasure; but servants and the poorer sort of women have seldom an opportunity of concealing a big belly, or at least the consequences of it. Bernard de Mandeville
Since hydrogen is a constituent of most of our electrolytic solvents, the definition of an acid or base as a substance which gives up or takes up hydrogen ion would be more general than the one we used before, but it would not be universal. Gilbert Newton Lewis
We frequently define an acid or a base as a substance whose aqueous solution gives, respectively, a higher concentration of hydrogen ion or of hydroxide ion than that furnished by pure water. This is a very one sided definition. Gilbert Newton Lewis
We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms. Gilbert Newton Lewis
There are so many things I'd like to change in the industry. Everything from the reliance of style over substance to their reluctance to hire me for big budget blockbusters, but the thing I would love most would be if they understood people don't have to be Hollywood beautiful to be sexy or interesting.

Our works and our play. All our pleasures experienced as the pleasure of love. What could be better that? To feel in one's work the tender and flushed substance of one's dearest concern. Mary Richards
A chemical substance is a material with a specific chemical composition. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory.
An element is a chemical substance that is made up of a particular kind of atoms and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmutated into another element through a nuclear reaction.
As a child, what captivated me was reading the poems myself and realizing that there was a world without material substance which was nevertheless as alive as any other. Mary Oliver
