When I was studying at Purdue, we learned our thermodynamics from an antique steam engine. When I went back in 1964, I found the laboratories packed with the most modern equipment for the study of thermodynamics, some of which had been built by the students themselves.
Try squeezing a handful of water, and see how quickly it disappears. But relax and let your hand flow in the same water, and you have the experience of the water as long as you like.
Any solid lighter than a fluid will, if placed in the fluid, be so far immersed that the weight of the solid will be equal to the weight of the fluid displaced. On floating bodies I, prop 5.
The discovery of superfluidity opened up a new understanding in the science world.
Know from the rivers in clefts and in crevices: those in small channels flow noisily, the great flow silent. Whatever's not full makes noise. Whatever is full is quiet.
The rigidity of a bottle's form does not affect the fluidity of the liquid it contains.
A cylinder of air reaching to the top of the atmosphere is of equal weight with a cylinder of water about 33 feet high.
See with what force yon river's crystal stream Resists the weight of many a massy beam. To sink the wood the more we vainly toil, The higher it rebounds, with swift recoil. Yet that the beam would of itself ascend No man will rashly venture to contend. Thus too the flame has weight, though highly rare, Nor mounts but when compelled by heavier air.
As with narrow-necked bottles; the less they have in them, the more noise they make in pouring out.
All things want to float.
Water its living strength first shows, When obstacles its course oppose.
Water does not resist. Water flows. When you plunge your hand into it, all you feel is a caress.
Bubbles are very simplified versions of some of the basic laws of the universe.
The floating vapour is just as true an illustration of the law of gravity as the falling avalanche.
The most direct evidence of the wonderful plasticity and elasticity of red corpuscles is obtained when they are watched in a current, where they can be caught against a projecting edge and bent by the pressure of the current flowing past them.
The waves belong to the water. Does the water belong to the waves?
Buoyed by water, he can fly in any direction - up, down, sideways - by merely flipping his hand. Under water, man becomes an archangel.
Water runneth smoothest where it is deepest.
At 17, I went to an engineering college, the entire reading was about fluid mechanics and steam engines and what not, so I drifted from arts, literature and even cinema, because in Aligarh there were a limited number of theatres.
Of the four elements water is the second in weight and the second in respect of mobility. It is never at rest until it unites with the sea.
A field of water betrays the spirit that is in the air. It is continually receiving new life and motion from above. It is intermediate in its nature between land and sky.
