This is my first attempt at participating in Linda G. Hill’s fun weekly series post called One-Liner Wednesday. It seems like an interesting thing to do and this should help me to remember what day it is. Her rules are listed below, along with this picture of the birds sitting on the telephone lines and I guess I am supposed to include this somewhere in my post.
“The rules that I’ve made for myself (but don’t always follow) for “One-Liner Wednesday” are:
- Make it one sentence.
- Try to make it either funny or inspirational.
- Use our unique tag #1linerWeds.
- Add our very cool badge to your post for extra exposure!
- Have fun!”
I looked over a few of the other entries and I am a bit confused about Rule number 1, as it seems that everyone wrote more than one sentence, however I guess the post IDEAS written by Sight-Journey could be considered to be one sentence, but it is a run on sentence. I will ignore Rule 1, however I will include a one-liner being, Sir Francis Bacon said, “In order for the light to shine so brightly, the darkness must be present”, and then I will try to relate this one-liner to the word ‘priorities’ which should satisfy Rule 1 and Rule 3. I guess my post title covers Rule 4 and I plan to have fun writing this, so Rule 5 is covered. All that is left now is foe me to satisfy Rule 2 and I will make this up as I go along, so I am not sure if it will be funny or inspirational, but you can be the judge of that.
Science and physics have both changed like everything else over the years from antiquity till modern times. The ancient Greeks talked about an element known as ether this discussion kept on going till it got to the modern physicists of our day, and it is a key to understanding how people perceive our world and the universe. Luminiferous means light bearing or something that produces or transmits light and ether was postulated as the medium for the propagation of light. This study of light is also the study of how things change, ideas and opinions change, which usually happens gradually over time and progress is impossible without change. This substance ether is something that almost all scientists, mathematicians and philosophers believed in at one time or another. If this short article just peeks your interest, and you have to know more about ether, than one day when my third book is published, ‘So You Want To Learn Calculus’, you can read my last chapter and learn all about the speed of light, matter, energy, relativity, electromagnetism and electron theory, as all these topics tie into this mysterious substance called ether that was used to explain science. Over the course of time, science has changed and it is still changing, ideas were clarified and then reclarified and it was often felt that everything in the universe would eventually be rationally demystified!
We all know the difference between light and dark, or do we? Visible light is something that we see every day, but understanding its nature is a mystery that has puzzled man for centuries. Ancient Greek scientists postulated that every visible object emits a steady stream of particles, while Aristotle concluded that light travels in a manner similar to waves in the ocean. These are two different viewpoints and it had to wait till Albert Einstein till they were combined together and we got our first real understanding about light. If only the Greeks could have gotten their priorities straight and put these two different ideas together, and understood that light is both a particle and a wave, the world could have been saved from 20 centuries of arguing about this mystery. The wave point of view predicts that light in a wave-like form, producing energy that traverses through space in a manner similar to the ripples spreading across the surface of a still pond after being disturbed by a dropped rock. The opposing view holds that light is composed of a steady stream of particles, much like tiny droplets of water sprayed from a garden hose nozzle. Opinions have wavered with one view prevailing for a period of time, only to be overturned by evidence for the other.
Aether (also spelled ether) is a philosophic and scientific concept denoting the existence of a fine substance (ponderable or imponderable) underlying the entirety of natural reality. Aether in Greek mythology is probably first mentioned by Hesiod a Greek poet as a figure of the Highest or Superior Heaven. ‘Higher’ than it, only its ‘mother’ Nix “The Night” and its ‘father’ Erebus “The Dark”. So, Aether is issued from the dark, the dark of the night and the dark of the cosmos; ‘his’ sister is Hemera being “The Day”.
People were aware that sound travelled in waves, and that water had waves, and that waves would travel down a taught string in musical instruments, and naturally they assumed that light also traveled in waves. However unlike sound and water light could travel through the vacuum of space, so space had to be made up out of some kind of light-carrying medium which eventually got termed luminiferous aether (sometimes spelled ‘ether’) which had to permeate all of space.
Any question that can be answered by experiment is non-philosophical and Anaxagoras of Clazomenae counterposed two principles, Chaos and Nous, for two types of substances, Air and Aether. Aristotle treated the Aether as the finest of substances that filled up space, he thought it was a fifth ‘element’ alongside Air, Water, Fire and Earth which he founded on the principle that nature abhorred a vacuum or nothingness. The substance of ether changed with opinions given by Baruch Spinoza a Dutch philosopher, Descartes’ put forth a notion of a vortical occupation of space, and Leibniz’s came up with a monist theory of monads. Robert Fludd an English physician suggested that the Aether was ‘subtler than light’, and before all these men Empedocles of Acragas, speculated that light traveled with a finite velocity. Later Anicius Boethius attempted to document the speed of light, but his work stopped after being accused of treason and sorcery, and he was decapitated for his scientific endeavors. People knew that light had to be faster than sound and they got this by watching fireworks where the flash of light and color preceded the explosive sound by several seconds.
