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.

There are so many intricacies to our brain that won't be understood unless we start to look at the system as a whole. All these different details don't operate in isolation.
You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution.
Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.
