Isaac Newton’s Prism Experiment
Theories should be tested, and have efficient evidence in order to be considered as scientific. Isaac Newton’s prism experiment was a critical experiment in the physics community where Newton researched and tested white light to isolate the explain that white light was made of several colours of light.
In Newton’s day, colour was stated as being a mix of light and darkness, and white light obtained colour by passing through prisms. The resulting colour would depend on how much “darkness” was added to the white light. Newton questioned this theory because he noticed that when he smudged ink on a white piece of paper the resulting colour was grey, a colour that was not found on the colour wheel. Therefore, if

This way the light from the sun would not interact with any other lights. Second, he made sure that he had proper tools. He used glass prisms for this experiment, as glass was a material that would allow all the light to pass easily through the prism, whereas other materials may absorb some light. Since Newton wanted to isolate white light into its singular components it was important that when light entered one side of the prism, there wasn’t less light on the other side, or else he would not be studying the entirety of the white …show more content…
Then, he set up a glass prism so that the beams could pass through it. When the beams passed through it, the light refracted into what we know now as the colours of the rainbow. Refraction is the process of light rays changing direction as they pass from one material to another; this is because the rays are travelling at a different speed through the material, and therefore causing the light rays to bend. How he confirmed that the different colours formed from refraction of white light was he placed another prism behind the original prism, but instead, placed it upside down. The different colours of light refracted back into their original positions, therefore collecting back into white light. He concluded that the white beams of light can be further dissected into several different colours of light.
Every light that refracted, even at a slightly different angle was a different colour. In order to prove his explanation was scientific, Newton tested his theory with this carefully conducted experiment. We now consider white light as a product of several different colours, even though we cannot directly see them. Newton was then able to theorize how light is contained in refracting waves and this theory was later explored by many scientists that came after him. A reason that many consider Newton’s discoveries as ones that are hard to falsify is because we are able to visibly see the
He had produced an unknown ray being emitted from the tube that could pass through the paper. He found that this new ray would pass through most objects, casting shadows of solid substances. He first investigated with his hand and was surprised when he saw his bones. His discovery would open up an exciting field for doctors because now it was possible to stu...
Some genuinely testable theories, when found to be false, are still upheld by their admirers-for example by introducing some ad hoc auxiliary assumption, or re-interpreting the theory ad hoc in such a way that it escapes refutation. However, such a method either destroys or lowers its scientific status.” These criteria make it hard for pseudosciences such as astrology or dowsing to be considered science. There has also been large increases in the accuracy and use of technology is ensuring that there is more empirical evidence and proof that theories are being based on. Some may argue against the corrected ratio of falsified to accepted theories, but unless every theory in the history of science was to be measured that argument would be futile, and the above point would still
The article Best Idea: Eyes Wide Open by Richard Powers discusses different aspects of the scientific method. It begins by talking about a man named Abu Ali al-Hasan Ibn al-Haytham who made discoveries regarding vision. He did this by simply performing observations and having people stare directly at the sun. Ibn al-Haytham changed the way science was viewed by telling people to simply look in order to gain information. Later, William of Ockham came up with the idea that “when you have multiple ways to explain something, go with the one that has the least amount of assumptions” (Powers, 1999, p. 4). My interpretation of this is that you shouldn’t make something harder than it needs to be. Do not assume, but rather work with the observations and experiments that you have performed. This idea eventually became known as Ockham’s Razor. Rene Descartes went in a different direction and believed that all science can be demonstrated by a series of deductions and self-evident facts, instead of something that is run through observation and experimentation.
In this essay, published in 1738, Voltaire explains the philosophies of not only Newton, but in a large part Descartes because of his contributions in the fields of geometry. In Voltaire's concise explanation of Newton's and other philosophers' paradigms related in the fields of astronomy and physics, he employs geometry through diagrams and pictures and proves his statements with calculus. Voltaire in fact mentions that this essay is for the people who have the desire to teach themselves, and makes the intent of the book as a textbook. In 25 chapters, and every bit of 357 pages, as well as six pages of definitions, Voltaire explains Newton's discoveries in the field of optics, the rainbow spectrum and colors, musical notes, the Laws of Attraction, disproving the philosophy of Descarte's cause of gravity and structure of light, and proving Newton's new paradigm, or Philosophy as Voltaire would have called it. Voltaire in a sense created the idea that Newton's principles were a new philosophy and acknowledged the possibility for errors.
Isaac Newton’s story of how an apple falling from a tree that hit his head inspired him to formulate a theory of gravitation is one that all school children grow up hearing about. Newton is arguably one of the most influential scientific minds in human history. He has published books such as Arithmetica Universalis, The Chronology of Ancient Kingdoms, Methods of Fluxions, Opticks, the Queries, and most famously, Philosophiæ Naturalis Principia MathematicaHe formulated the three laws of gravitation, discovered the generalized binomial theorem, developed infinitesimal calculus (sharing credit with Gottfried Wilhelm Von Leibniz, who developed the theory independently), and worked extensively on optics and refraction of light. Newton changed the way that people look at the world they live in and how the universe works.
God knew the people had noticed a pattern of a sun in the sky during the day and gone at night and so explained this phenomenon in a way that would get his message across in a way that we could see, since we did not have the science to test this.

In 1794 he was elected a member of the Manchester Literary and Philosophical Society. There he read his papers and identified the phenomenon of colour blindness, which he and his brother shared. When showed a colour spectrum besides blue and purple Dalton was only able to recognise one other colour, yellow. Or as he says ?that part of the image which others call red appears to me little more than a shade or deflect of light. After that the orange, yellow and green seem one colour which descends pretty uniformly from an intense to a rare yellow, making what I should call different shades of yellow?
Before delving into the philosophy of color and the questions posed by different pieces of art, the biological basis process of HOW color is seen should be explained. The retina is a neural sheet, containing the photoreceptors called rods and cones that is located at the back of the eye. Between the retina and the optic nerves leading to the brain are a series of cells that create a lateral inhibition network of the light/dark signals from the photoreceptors (1). This throws away a lot of the information generated by the photocells and gives the brain a "picture" of the edges of light and dark. The contrasts are created, leaving the brain to fill in the rest. Color vision is even more complex. Cones (the light adapted photoreceptor) contain three different photopigments, red, green, and blue, each corresponding to a particular wavelength of light (2). Color is a property of three things: the ratio of red/green activation, blue response, and value or lightness (3). The brain utilizes visual inputs to determine each of these, thus generating the characteristic color.
The theory of photography originated from the discovery of the camera obscura phenomenon – light that enters a darkened chamber through a small hole is projects an identical inverted image on the interior wall of the outside scene. The first recordings of scientists recognizing this concept was in the writings of Greek philosopher, Aristotle (384 – 322 BC).
So how do we get to see a rainbow in the sky? First condition that must be fulfilled is that the sun must be shining, more to that, the sun must be behind you and raindrops must be present in the sky. When these three conditions are present, then the sun will shine to the little droplets that act a prism. The rays will get refracted twice, thus, producing different variety of colors. However, each drop will only produce one color thus ...
Generally, science is a hotly discussed and vehemently debated topic. It is difficult to achieve consensus in science, considering the fact that ideas are diverse about even science definition, leave alone the true interpretations and meaning of scientific experiments, philosophies and discoveries. However, these arguments, disagreements as well as continuous trials to find a better reasoning, logic and explanation are exactly what have always been driving science progress from art to art form. It is worth noting that, in Philosophy of Science: A Very Short Introduction, the Author-Samir Okasha explore various way of looking at science via the prism of life by citing a variety of scientific experiments, and providing examples from history of science.
Over the years there have been many more important figures in astronomy. One extraordinary astronomer was Galileo Galilei who invented the first refractor telescope in which light is bent to enlarge an image of the sky (“Galileo Project”). The next great astronomer to follow him was Isaac Newton. Newton had made a great amount of contributions to astronomy during his life. He further proved that the Earth was not the center of the universe and he also invented the Newtonian reflector telescope which is still used today in observatories. Also, he discovered that light could be split into a visible spectrum of colors. Spectral colors from stars would later be used to determine their size, temperature, chemical composition, and even the direction the star is moving.
Beginning with the scientific revolution in the fifteen hundreds, the Western world has become accustomed to accepting knowledge that is backed by the scientific method, a method that has been standardized worldwide for the most accurate results. This method allows people to believe that the results achieved from an experiment conducted using the scientific method have been properly and rigorously tested and must therefore be the closest to truth. This method also allows for replication of any experiment with the same results, which further solidifies the credibility and standing of natural science in the world. Another aspect that allows for the reliability on the natural sciences is the current paradigm boxes, which skew the truth to remove anomalies. This affects the outcome of experiments as the hypotheses will be molded to create results that fit the paradigm box.
