William Henry Bragg Quotes

We boil at different degrees.

When the water starts boiling it is foolish to turn off the heat.

Let it them be put into any clean oven vessel of china or stoneware which should be wider at the top than at the bottom. so that there may be the largest surface above to favor the evaporation.

The difference between a gas and a liquid is that in the former, the atoms and molecules move to and fro in an independent existence, whereas in the latter, they are always in touch with one another, though they are changing partners continually.

The physics of water is central to cooking, because food is mostly water. All steak that you cook is actually boiled on the inside.

Into this pour the purified juice: and put it into a pan of water come almost to a boil and continue nearly in the state of boiling until the juice is found to be the consistency of a thick syrup when cold. It is then when cold, to be corked up in a bottle for use.

Something can be real - actually existing, not merely illusory - and yet not be fundamental. Scientists used to think that heat, for example, was a fluidlike substance called 'caloric' that flowed from hot objects to colder ones.

Bubbles are very simplified versions of some of the basic laws of the universe.

From "Wetness and Water" How does a part of the world leave the world? How can wetness leave water? Do not try to put out a fire by throwing on more fire. Do not wash a wound with blood. No matter how fast you run, your shadow more than keeps up. Sometimes it's in front. Only full, overhead sun diminishes your shadow. But that shadow has been serving you. What hurts you blesses you. Darkness is your candle. Your boundaries are your quest.

I want to be the condensation on the glass. I want to be that phenomenon that takes place between hot and cold.

Salt water when it turns into vapour becomes sweet, and the vapour does not form salt water when it condenses again. This I know by experiment. The same thing is true in every case of the kind: wine and all fluids that evaporate and condense back into a liquid state become water. They all are water modified by a certain admixture, the nature of which determines their flavour.

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.

Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

I don't mean to say it's not fresh on the space station, but there's nothing like new, cold air coming into the capsule.

Bubbles are just a little liquid soap and a breath of air.

Bubbles are round for the same reason that planets are spherical. The universe itself is like bubbles.

The trouble with vitreous water is that vitrification should be impossible.

The temperatures required for caramelization and browning almost always far exceed the boiling point of water. So the presence of water on the surface of a food, or on the bottom of a pan, is a signal that browning can't yet occur.

The laws of thermodynamic s are such that if the water is getting warmer - and I believe it is - the energy of the weather is going to go up.

The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have proved by actual experiment that, in exact proportion to the force with which this machine works, heat is abstracted from the electrical battery. You see, therefore, that living force may be converted into heat, and that heat may be converted into living force, or its equivalent attraction through space.

Cost is always an object - the second law of thermodynamics sees to that

Whether you boyle snow or pound it, you can have but water of it.

If the film isn't suspenseful, i.e. the pressure cooker situation of what's going on in the movie, if that's not part of it, if the threat of violence and the temperature isn't always going up a notch every scene or so, then the movie is going to be boring. It's not going to work.

If a drink was ice cold, it would be impossible to drink. Because it would be solid. Here's a drink, Mitch - it's ice cold. I guess I could lick it.

From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
