Thomas Young
(1773-1829)
Thomas Young was a brilliant man throughout his life. At a young age of fourteen, he was familiar with Latin, Greek, French, Italian, Hebrew, Arabic, and Persian. He was so educated in a variety of areas that his peers called him Phenomena Young. This Englishman found interest in languages, medicine, nature, and light. He did his studies in London, Edinburgh, and Göttingen, and practiced medicine in London. With his strong interest in sense perception, he was able to make many realizations and discoveries about the eye. For example, he was the first to realize the eye focuses by changing the shape of the lens, he discovered the cause of astigmatism, and he and Helmoltz initiated the three color theory of perception. In 1801, regardless of the uncertainty from other scientists, his double-slit experiment established that light was a wave motion, making his famous. Over the years, he gained new interests. He started studying Egyptology, and while he was one Napoleon’s expeditions he started studying the texts of Rosetta Stone. This in time helped to decipher the ancient Egyptian hieroglyphic writing. Some other interests that Young acquired over the years, leading him to more discoveries are surface tension, elasticity and energy. He even worked as a professor at schools, including the Royal Institution and Cambridge University. Thomas Young was a smart, well educated English physician and physicist. His love for his work and interests allowed him to make discoveries that help us to this day, and to be remembered and acknowledged as
“…a man alike eminent in almost every department of human learning.”

1) A stationary body will stay stationary unless an external force is applied to it; 2) Force is equal to mass times acceleration, and a change in motion is proportional to the force applied; and 3) For every action, there is an equal and opposite reaction.

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...
There he inspired many students and tutored them to become professionals in the medical field. Many of these students included Fabricius ab Aquapendente (gave the first clear description of the semi lunar valves of the veins, which later provided many people with a crucial point in his famous argument for circulation of the blood) and Volcher Coiter (described human embryology as well as the comparative osteology of animals and illustrated his own work.... ... middle of paper ...
Thomas Day was born in Dinwidee, Virginia in 1801 to a free slave mother. With the law that allowed children to be born free if their parents were free, Day was born free and did not have to be a slave. His family had been free since the early 18th century. He and his brother were educated by private tutors and they were trained by their father in cabinetry and carpentry. Thomas’ brother eventually began to study theology and he emigrated to Liberia in 1930 and was a Baptist missionary, eventually became one of the signers of the Liberian Declaration of Independence and a prominent statesman there. He’s known as one of the founding fathers of that nation.
In this experiment, Newton placed a second prism 5 or 6 yards away from the first. At first, when the light passed through the prisms, his results were the same as the first experiment. However, when the prisms were moved farther away from the wall onto which the light was being projected, the light projected from the prisms became white again. When they were moved even farther, the light became colored again, but the color scale was inverted from the original scale. According to the accepted theory of light, the second prism changed the color of the light projected onto the wall. Therefore, Newton’s results once again contradicted the accepted theory of light. He also rotated the prisms to test if this would have an effect on the light, but it did not. Due to these observations, Newton concluded that light was in fact a combination of all light on the spectrum of light, not just a mixture of light and
A man name Hester Gatty and, they had a son name George. Siegfried Sassoon was born on September 8, 1886 in Kent, England. Sassoon was the Eminent English Poet writer and soldier. His poetry both describe the horrors of trenches. Siegfried Sassoon began writing poetry as a child he was more interested in sports than in Scholastic Achievement. Siegfried had a good childhood, went into war as a soldier, and wrote poetry.
After he received his Bachelor of Arts degree in 1608, he was recommended by the principal of Magdalen was appointed tutor William Cavendish who eventually became the second Earl of Devonshire. Hobbes became part of the Cavendish family they were very close. In 1610 Hobbes accompanied his pupil to a trip to France and Italy. While in Europe he discovered that what he studied in Oxford came from what Europeans had learned. Thomas Hobbes then pursued to the classics which he has studied , before he went to Oxford and to which he has given much attention to.
The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs.

Psychologist Raymond Dodge and his student T.S. Cline developed the first camera-based technique for registering eye movement in 1901 [3]. They used a falling plate camera (also referred to as a photo-chronograph) to measure light reflected from the cornea. However, their method required the subject’s head to be motionless and was only capable of recording horizontal eye movement. Only a few years later, motion picture photography was applied to record eye movement. This technique was useful because it allowed for a frame-by-frame analysis of the eye’s movement allowing for quantitative research on a solid basis**.
Landscape painting was extremely important during the middle of the nineteenth century. One of the leading practitioners of landscape painters in America was Thomas Cole. He visited many places seeking the “natural” world to which he might utilize his direct observations to convey the untainted nature by man to his audience. His works resolved to find goodness in American land and to help Americans take pride in their unique geological features created by God. Thomas Cole inspired many with his brilliant works by offering satisfaction to those seeking the “truth” (realism) through the works of others.
Light rays gather through the opening of the telescope called the aperture and pass through the objective lens and refract onto a single point called the focal point. From there, the light rays continue in the same direction until it hits the eyepiece lens, which also refracts the light back into parallel rays. During the process, the image that enters our eyes is actually reverse of the original image and magnified because of the size in which we perceive the image.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose name is known by almost all living people. While most of these do not understand this mans work, everyone knows that his impact on the world is astonishing.
Working from these ideas, British physicist James Clerk Maxwell predicted mathematically the existence and behavior of radio waves in 1873. In 1886, physicist Heinrich Hertz from Germany and Elihu Thomson from America confirmed the existence of radio waves with demonstrations showing examples of reflection, refraction, and direction finding of radio waves. By 1904, Christian Hulsmeyer, a German inventor, applied for a patent for a device that used radio waves in a collision-avoidance device for ships.
