Having described the idea of the electromagnetic field, and that this field can carry waves, we soon learn that these waves actually behave in a strange way which seems very unwavelike. At higher frequencies they behave much more like particles! It is quantum mechanics, discovered just after ...
Now imagine this great drop of water with all of these jiggling particles stuck together and tagging along with each other. The water keeps its volume; it does not fall apart, because of the attraction of the molecules for each other. If the drop is on a slope, where it can move from...
1. The collection of physical effects resulting from the existence of charged particles, especially electrons and protons, and their interactions. Particles with like charges repel each other. Particles with opposite charges attract each other. 2. The electric current generated by the flow of electr...

Normally, water molecules attract each other under the action of positive and negative potentials, and the maximum positive electrostatic potential of water is 3.992 × 10–19 J and the maximum negative electrostatic potential is − 2.854 × 10–19 J. The surfactant has a hydrophilic...
* There are always particles of dust in the air. Dust tints sunsets and pollutes city air. The structure of the steel and the resulting properties will depend on how hot the steel gets and how quickly or slowly it is cooled. The Post Office was helpful, and Marconi applied in June 1896...
The flow was less strong and as he rubbed the side of his hand against the planking of the skiff, particles of phosphorus floated off and drifted slowly astern. "He is tiring or he is resting, "the old man said."Now let me get through the eating of this dolphin and get some rest ...
We have discussed some of the properties of large numbers of intercolliding atoms. The subject is called kinetic theory, a description of matter from the point of view of collisions between the atoms. Fundamentally, we assert that the gross properties of matter should be explainable in terms of...
