In What Year Was The Geiger Counter Invented

Geiger counters are instruments used to detect if objects are giving off nuclear radiation. They do this by measuring the amount of ionizing radiation. Alpha, beta, and gamma are the three types of ionizing nuclear radiation that the Geiger counters can detect. These devices are used primarily in the fields of physics, medicine, industry, and astronomy. They are also used to test the levels of radioactivity near nuclear power plants and can check for radiation in areas where uranium ammunition shells have been used.

Many people wonder in what year was the Geiger counter invented? The Geiger counter was created in 1908 by a man named Hans Geiger. The first device was only able to detect alpha particles and was not able to detect ionizing radiation until 1928. In 1947 a modern version of the Geiger counter was invented by a man named Sidney H. Liebson. These models are the ones that are currently being used today. 






Who Invented Twix

Twix is a popular candy confection manufactured by Mars Incorporated. This candy bar is smaller than others and usually comes packaged in pairs. They consist of a delicious caramel covered biscuit finger dipped in milk chocolate. Forrest Mars Sr. was the man who invented Twix candy bars in the 1930s. It was originally manufactured in the United Kingdom and did not make its way to the United States until 1979. In European countries the candy bar was called Raider, and when it came to the United States it was renamed the Twix Cookie Bar.

The gold wrapping of the Twix bar added to its popularity. Mars Incorporated also tested out different variations of the candy bar to increase its appeal in different parts of the world. Peanut butter was the first variation of the candy bar and other variations include Twix Miniatures, Chocolate Fudge Twix, and Twix Tea Breaks. In 2008 the company released a limited edition version of Twix called Twix Java. This bar consisted of a dark chocolate cookie covered with coffee flavored caramel and milk chocolate.

Who Invented The Stereo Microscope

The stereo microscope is essentially two compound microscopes designed to view samples at low magnification using light illumination. These two microscopes allow the sample to be viewed at the exact same point but at different angles. These angles allow the sample to be viewed in three dimensions. This microscope is typically used to perform work that requires a closer look such as dissection, watch-making, sorting, and microsurgery. They are also used to research the surface of solid specimens.

Horatio S. Greenough was the man who invented the stereo microscope. He was an American instrument designer and the son of a famous sculptor. In the 1890s Greenough submitted his stereo microscope plans to the Carl Zeiss Company. The company agreed to produce the microscope, but added an additional feature to the product that inverted prisms. His stereo microscope design became the forefather of the modern designs that followed. Greenough’s design has withstood the test of time and is still used for certain applications today. 

Who Invented The First Kidney Dialysis Machine?

Willem Johan Kolff was the man who invented the first kidney dialysis machine. Kolff was born in the Netherlands and attended Leiden University where he studied medicine. His father was doctor so as a child Kolff had a fear of watching his patients die. After graduating from Leiden University he experienced his fear and saw his own patient die due to kidney disease. It is believed that this is what led Kolff to begin focusing his time on developing artificial organs.

Kolff had little options to offer his patient who had passed. This frustrated him deeply and he sought out to find a solution to the problem. He began to experiment and create different artificial kidney machines. Due to lack of funding he moved to the United States where his ideas were more accepted. His work eventually led to the creation of the kidney dialysis machine which has saved the lives of thousands of people. Kolff passed away due to congestive heart failure on February 11, 2009. He was 97 years old. 

Who Invented Laffy Taffy

Laffy Taffy is a popular candy brand that consists of individually wrapped pieces of taffy available in different fruit flavors. Nestle was the company who invented laffy taffy in the 1970’s.  Laffy Taffy is currently sold under the Willy Wonka Candy Company division of Nestle. Laffy taffy also gained popularity from the 2005 film “Charlie and the Chocolate Factory.” The name laffy taffy refers to the actual texture of the candy itself and also to the silly and wonky fun it represents.

Each individual piece of laffy taffy has a joke printed on it to bring laughter to the people while they enjoy their taffy. Children send in their jokes to Nestle and if their joke is chosen it is printed on the wrapper with their names. Laffy taffy comes in rectangular shaped pieces and currently they also come in cords or ropes. The various flavors of Laffy Taffy are blue raspberry, cherry, strawberry, sour apple, grape, and banana. 

Who Invented Gene Splicing

The process in which strands of DNA are cut into pieces and spliced together is referred to as gene splicing. The strands of DNA are chemically cut using restriction enzymes. Restriction enzymes are used to cut specific base pair sequences of DNA only. There are thousands of these enzymes since strands of DNA vary. The restriction enzyme cuts the DNA at the specific base pair location which secludes that particular strand of DNA. They then add another DNA sequence to this strand and create the protein product of the new gene. The DNA strands that are combined are usually from various organisms.

Herb Boyer and Stanley Cohen were the men who invented gene splicing in 1973. They placed a gene from a toad called a Xenopus into bacterial DNA. A year earlier a scientist named Paul Berg actually used gene splicing to create DNA molecules. He was actually the first scientist to splice together DNA strands from two different organisms together. His research made the discovery of restriction enzymes by Daniel Nathans and Hamilton Othanel Smith possible. 

Who Invented The Snickers Bar

Snickers is a popular candy bar manufactured by Mars Incorporated. Mars Incorporated manufactures various products all over the globe. Out of all their products they are most famous for their confectionery items such as the Mars bar, M&M’s, Skittles, Twix, and Snickers. The snickers bar is a delicious blend of milk chocolate filled with peanut nougat, caramel, and roasted peanuts.

Have you ever wondered who invented the snickers bar? The snickers bar was invented in 1930 by Frank C. Mars and his wife Ethyl Mars. They first snickers bars were sold in the United Kingdom and Ireland and were called Marathon bars instead of snickers. The name was officially changed in 1990 which increased the popularity of the candy bar. The name snickers originated from one of the family’s favorite horses. In the year 2000 Snickers became the best selling candy bar in history and was named the most popular candy bar in the world.
