When a coil is operated with currents of very high frequency, beautiful brush effects may be produced, even if the coil be of comparatively small dimensions. The experimenter may vary them in many ways, and, if it were nothing else, they afford a pleasing sight.
Interpretation
Tesla highlights the aesthetic beauty and versatility of high-frequency currents in coils.
In this quote, Nikola Tesla describes the visual and experimental beauty that can be achieved through the use of high-frequency currents in coils. He suggests that even small coils can produce striking 'brush effects' when operated at these frequencies, allowing for various experiments and offering pleasing sights that go beyond mere scientific utility.
In practice
In a science class to illustrate the beauty of experiments.
Even matter called inorganic, believed to be dead, responds to irritants and gives unmistakable evidence of a living principle within. Everything that exists, organic or inorganic, animated or inert, is susceptible to stimulus from the outside.
Our senses enable us to perceive only a minute portion of the outside world.
Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding, the sphere of external influence extends to infinite distance.
The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.
The Secretary of Hygiene or Physical Culture will be far more important in the cabinet of the President of the United States who holds office in the year 2035 than the Secretary of War.
I am unwilling to accord to some small−minded and jealous individuals the satisfaction of having thwarted my efforts. These men are to me nothing more than microbes of a nasty disease. My project was retarded by laws of nature. The world was not prepared for it. It was too far ahead of time, but the same laws will prevail in the end and make it a triumphal success.
The average ground temperature of the Earth is impossible to measure since most of the Earth is ocean...So this average ground temperature is a fiction.
There are many instances in science, where those closest to the intricacies of the subject have a more highly developed sense of its intractability than those at some remove. On the other hand, those at too great a distance may, I am well aware, mistake ignorance for perspective.
The history of astronomy is a history of receding horizons.
I think it is a peculiarity of myself that I like to play about with equations, just looking for beautiful mathematical relations which maybe don't have any physical meaning at all. Sometimes they do._x000D_ _x000D_ At age 60.
These slender little people (Homo Habilis), the size of modern 12 year olds, were devoid of fangs and claws and almost certainly slower on foot than the four legged animals around them. They could have succeeded in their new way of life only by relying on tools and sophisticated cooperative behavior
Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.
