“Substances can exist in three states – gas, liquid and solid. Water exists in all three states: gas (steam or water vapour), liquid (ordinary water) and solid (ice}. Properties of gases, liquids and solids are different.”

“All of our conscious states, without exception, are caused by lower level neurobiological processes in the brain, and they are realized in the brain as higher level, or system features. It's about as mysterious as the liquidity of water, right? The liquidity is not an extra juice squirted out by the H2O molecules, it's a condition that the system is in; and just as the jar full of water can go from a liquid to solid, depending on the behavior of the molecules, so your brain can go from a state of being conscious to a state of being unconscious, depending on the behavior of the molecules. The famous mind body problem is that simple.”

“The fact is always obvious much too late, but the most singular difference between happiness and joy is that happiness is a solid and joy a liquid.”

“Water! Of all liquids on Earth, the only one chosen for scrubbin' and flushin'. The liquid they rinse baby's nappies in, the fluid that floods the gutters o' this cloud-squeezer town; a single drop o' water discolors a glass of Irish, and you, false friend, are wantin' me to pour this abrasive substance into me defenseless body!”

“I have seen the Mississippi. That is muddy water. I have seen the Saint Lawrence. That is clear water. But the Thames is liquid history.”

John Burns (1858–1943) English trade unionist and politician

Quoted in the Daily Mail (25 January 1943)

“When two surfaces at different temperatures are in presence of one another with a gas between them, there exists a force tending to separate them. The assumption of this force explains a very great number of phenomena, including the motion of the arms of Mr. Crooke's radiometers and the so-called spheroidal state of liquids.”

George Francis FitzGerald (1851–1901) Irish physicist

March 1878 quoted in [The Scientific Writings of the Late George Francis FitzGerald, https://books.google.com/books?id=2le7lpdAJ5EC&pg=PA18] (p. 18)

“Wherever there exists a difference of temperature… it is possible to have also the production of impelling power. …All substances in nature can be employed for this purpose, all are susceptible of changes of volume, of successive contractions and dilatations, through the alternation of heat and cold. All are capable of overcoming in their changes of volume certain resistances… A solid… A liquid… An aeriform fluid… If it is enclosed in an expansible space, such as a cylinder provided with a piston, it will produce movements of great extent. Vapors of all substances capable of passing into a gaseous condition, as of alcohol, of mercury, of sulphur, etc., may fulfil the same office as vapor of water. …Most of these… have been proposed, many even have been tried, although… without remarkable success.”

Nicolas Léonard Sadi Carnot (1796–1832) French physicist, the "father of thermodynamics" (1796–1832)

Reflections on the Motive Power of Heat (1824)

“Laplace made many important discoveries in mathematical physics… Indeed, he was interested in anything that helped to interpret nature. He worked on hydrodynamics, the wave propagation of sound, and the tides. In the field of chemistry, his work on the liquid state of matter is classic. His studies of the tension in the surface layer of water, which accounts for the rise of liquids inside a capillary tube, and of the cohesive forces in liquids, are fundamental. Laplace and Lavoisier designed an ice calorimeter (1784) to measure heat and measured the specific heat of numerous substances; heat, to them, was still a special kind of matter. Most of Laplace's life was, however, devoted to celestial mechanics.”

Morris Kline (1908–1992) American mathematician
