He is currently the Chief Technology Officer at YouTube even though it has been bought by Google. Jawed Karim was...
Who Invented Chemotherapy?

Who Invented Chemotherapy?...

Chemotherapy is a very important medical procedure used widely to treat people with severe illnesses, specifically cancer patients. Designed to kill cells, it is guaranteed to have positive effects against cancerous tumors and microorganisms. It affects the cells in hair follicles, digestive tract as well as bone marrow. People who undergo it usually experience hair loss or alopecia, inflammation of the digestive tract lining or mucositis and decreased blood cell production or myelosuppression. Aside from these significant details, it is good to know other important information about it including who invented chemotherapy. The Invention of Chemotherapy Who invented chemotherapy? Based on reports, it was Alfred Gilman and Louis S. Goodman who invented this kind of treatment. In the 1940s, the U.S. Department of Defense hired them to conduct research on the use of nitrogen mustard as therapeutic agent. They found that such chemical warfare agent could actually treat lymphoma. After that, Eli Lilly discovered the effectiveness of Madagascar periwinkle in blocking tumor cell proliferation. In 1965, the effectiveness of combination chemotherapy as cancer treatment was discovered. Additional Facts and Other Interesting Information The use of drugs and chemical substances as medication originated in ancient India, where the people once adhered to the practice referred to as Ayurveda. As part of this practice, people herbs and metals were used widely to treat various types of illnesses. By the 10th century, a Persian physician named Muhammad ibn Zakariya Razi started the chemical use for medical purposes. Amongst the items he used were alcohol, bitumen and tar. Likewise, he also used other unconventional materials to treat diseases such as arsenic salts, mercuric salts and copper. Primarily, doctors recommend chemotherapy to patients in order to palliate symptoms or prolong life. This specific kind...
Who Invented Chewing Gum?

Who Invented Chewing Gum?...

To find out who invented chewing gum, several names have to be mentioned. In fact, there were even ancient races that first came up with the idea of a chewing gum and should also be considered when talking of the first chewing gum maker. Thomas Adams Records say that in 1869, Thomas Adams was the one who invented chewing gum accidentally while trying to make rubber products out of chicle. In the same year Antonio Lopez de Santa Anna had introduced Adams to an interesting elastic sap material taken from the sapodilla tree. The ancient Mayans had chewed the same sap which was later known as chicle. However, Adams, considered the first chewing gum maker, was unsuccessful at converting chicle into rubber products like tires, boots, and toys. Later, Adams suddenly thought of chewing the chewy material in his mouth and found it edible. He added flavor to it and was soon selling the flavored gums in 1871 in drug outlets. It was sold for a penny per piece. He also opened a gum factory in New York in the same year. Adam’s Tutti-Frutti In 1888, Adams produced his specially flavored Tutti-Frutti with the use of vending machines. These were put in subway stations in New York. Now, the chewing gum was mass produced and fully commercialized. Adams, the man who invented chewing gum, made many significant contributions to the development of this sweet chewy delicacy so that he is considered the first chewing gum maker. John B. Curtis In 1848, the Pure Spruce Gum from Maine appeared in the market. This was manufactured and sold by John B. Curtis. Curtis is another name to consider when thinking of who invented chewing gum. Earlier, the North American Indians had...
Who Invented Plastic?

Who Invented Plastic?

Introduction Plastic is a general word describing synthetic or partly synthetic materials or objects. Plastic comes from a Greek word meaning “can be molded.” It refers to the ability to be molded during manufacture into a different shape. Hence the word “plasticity.” Invention of Plastic The first person who invented plastic was Alexander Parkes, a native of Birmingham, England. He called his work Parkesine after himself. The plastic he invented was organic. It was made from cellulose treated with a solvent and nitric acid. It could be molded into any shape when heated. When it cooled, the Parkesine plastic kept its shape. Parkes showed off his invention to the world in the Great International Exhibition in 1862. His plastic design won the bronze medal. Parkes thought that what he’d invented could replace rubber. But manufacturers soon grew cool to the Parkesine due to the high cost of its raw materials. Celluloid Plastic The next step in the invention of plastic occurred in the United States in the late 19th century. Billiards was getting very popular. Back then ivory was used to make billiard balls. Thousands of elephants were slaughtered only for their ivory tusks. Even back then it was impractical and expensive, not to mention cruel as later animal rights advocates would cry out. Then John Wesley Hyatt came to the rescue. One day as Hyatt was working in his shop, he spilled a bottle of collodion. When it dried, he discovered it was flexible yet strong. Hyatt experimented with his discovery. He found tat collodion by itself wasn’t tough enough for use in billiards. It was much too fragile. But when he added camphor to it, heated and then molded it, it became durable. Hyatt had invented celluloid...
Who Invented the Very First Camera?

Who Invented the Very First Camera?...

The history of the camera is long and complex. Louis-Jacques-Mande Daguerre invented the first photographic device in 1836. George Eastman popularized photographic film in 1885. However, camera like devices appeared years earlier. The Camera Obscura The first known instance of people being aware of photography theory was in 5th century China. A Chinese named Mo Ti observed the following effect. When light rays of an illuminated matter are reflected and go through a dark area, it will produce an inverted but otherwise identical copy. In 1000 AD, Alhazen created the pinhole camera or camera obscura. The history of the camera indicates that the next important discovery was made in 1727. That was when Johann Schulze learned silver nitrate became dim when it was exposed to light. Niepce’s Image Then in 1827, Frenchman Joseph Niepce managed to make a photographic image. He used the camera obscura for this task. Although the device had been around for a while, it was only used for illustration. Niepce called it the sun prints. But they were the descendants of modern photos as they also used light to produce the image. However it took eight hours to produce the image and it eventually faded. Niepce’s experiment was followed by that of Daguerre. Daguerre played an important role in the history of the camera. The daguerreotype method helped preserved images and took less than half an hour to produce the image. A different type of camera called the calotype was invented by William Talbot in 1840. By the 1880s, the success of Daguerre and Talbot spurned on other inventors. When gelatin dry plate was invented, it greatly helped in the quality of the output. As technology improved, cameras of all shapes and sizes started coming...
