Pioneers/Discovery of X-Radiation in Dentistry In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube. 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...
During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode-ray tube when he noticed nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole hand, but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still shown through, he then determined that a new ray was being emitted that could penetrate through thick materials. (1.) He later found that the rays could pass through most anything, but would cast a shadow of solid objects; these shadows could then be captured on film. Among the solid objects Roentgen shot with these rays was human tissue, the rays would penetrate the tissue, but the bones would cast a shadow, which could then be caught on film. One of Roentgen’s first experiments with X-rays was on his wife’s hand where, on the film, you could see her hand bones and her wedding ring. (1.) While the discovery of x-rays was a huge advancement in medical technology, they were not used in the medical field at first. Instead the mystical invisible rays that could penetrate solid objects were used in the industrial field.
Due the fact that he was not there to tend to his wife during her dying days, he decided to end his career of painting and tried to develop a technology that could transmit and receive information that was faster than the current methods that were available during th...
At the beginning when Crookes started his studies with the fluorescent light, it was not understood very well, just because of the mysterious rays, which were called “cathode rays” because they were seemed to be produced by the negative electrode. But his experiments, was so helpful to show how the new information was important for the nature of the unknown rays.
The first incandescent light dates back to 1802, when English chemist Humphrey Davy “passed a current through a platinum wire” [4]. Davy then saw the platinum wire glow and produce a fleeting light. However, the light was neither bright nor long lasting enough to be a reliable light source [4]. In February 1879, English chemist Joseph Swan (Figure 4) created the first practical light bulb.

Before his invention of germ theory, Louis Pasteur proved the widely unpopular hypothesis that fermentation was caused by living cells. While still in school, he completed research in the optical activity
Lastly, we have finger printing in forensics in 1880 and the machine gun in 1885. The electric lamp, or the first electric light, was invented by Humphry Davy in 1807 in Britain. He was a chemist professor and devoted his life to chemistry. He discovered many important elements of the periodic table such as potassium, sodium, barium, strontium, calcium and magnesium. He created the first light by connecting
Dentists have been around for thousands of years. Dentistry got its start in the Indus Valley of India And Pakistan. “The earliest history of treating tooth related problems goes all the way back to 7000 BC, where the Indus Valley Civilization shows evidence of treating the mouth for tooth decay. The first method of treatment was bow drills, which were ancient primitive tools used for woodworking and treating tooth problems.” (http://www.todayifoundout.com/index.php/2012/12/the-history-of-dentistry/)paragrah1 .These industrious would be dentists were master bead makers who used bow drills to cure tooth problems. From the ancient Egyptians to the Greco-Romans to early Chinese civilizations dentists have existed to aid the people with their teeth problems.
He studied objects to discover what affected their ability to move on surfaces. He never published his theories therefore has never received credit for his findings.
In 1879, after spending $40,000, and performing 1,200 experiments, he succeeded. He made a light bulb using carbonized filaments from cotton thread. Carbonized thread is ordinary cotton sewing thread that has been burned to an ash. The light bulb burned for two days. The electric light took the greatest amount of time and required the most complicated experiments of all his experiments.
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.
From a discovery made by one of his associates, he patented the Edison effect (now called thermionic diode), which is the basis for all electron tubes. Edison will forever be remembered for his contributions to the incandescent light bulb. Even though he didn't dream up the first light bulb ever crafted, and technology continues to change every day, Edison's work with light bulbs was a spark of brilliance on the timeline of invention.
