Who Invented the Calendar We Have Today?...

Introduction The modern calendar is known as the Gregorian Calendar. It is named after Pope Gregory XIII who favored it over the Julian Calendar. But Gregory XIII only approved the calendar that bears his name. The actual inventor was Alosyius Lilius. Alosyius Lilius Biography Lilius was an Italian astronomer, physician and chronologist. He was from Ziro in Calabrio, Italy. Lilius’ chosen profession was medicine. He studied in Naples to become a doctor and served under the earl Carafa, a prominent nobleman. Some time later, Lilius began to teach in the Perugia University in 1552. Aside from his interest in medicine, Alosyius Lilius was also fascinated by time keeping and calendars. He noted problems with the Julian Calendar, the one that was being used in his time. So he wrote a paper proposing a new calendar system. But it did not get attention until years after his death in 1576. After Alosyius died, his brother Antonio turned over his manuscript to Pope Gregory XIII. The latter put it for review before a council. It was approved after some changes made by another astronomer, Christopher Clavius. In 1582, Pope Gregory XIII issued a papal bull superseding the Julian with the Gregorian Calendar. It was slowly adopted by Christian countries one after the other. Now it is the system used by virtually everyone in the world. Why the Gregorian Calendar Replaced the Julian Calendar Julius Caesar invented the Julian system. All months had either 30 or 31 days, except for February. February or Februalia had 29 or 30 days depending on whether it was a leap year or not. Caesar named one month after himself, July. When Octavian became Roman emperor, he also renamed a month to August, after his new imperial...
Who Invented the Hummer?

Who Invented the Hummer?...

The history of the Hummer began with the Humvee. The Humvee was a vehicle developed by AM General Corp. for the US military. It became very popular and General Motors would go on to cerate a model for civilians which came to be known as the Hummer. The vehicles were first sold in 1992. Background of the Hummer The original Humvees were constructed in the early 1980s by AM General Corporation. The earliest models were made in Mishawaka in Indiana. The Humvees were made at the behest of the US military. The earliest Humvee models were strictly for military use and were fitted with military equipment such as radar. The history of the Hummer was changed when the vehicle was made public. The design of the vehicle captured the media’s attention. The Hummer first got public attention when the vehicle was shown over ESPN. People marveled at how easily it was able to navigate the uneven terrain. However it was the Gulf War that really brought the Humvee into mainstream public consciousness. The Hummer Emerges Sensing the strong public demand, AM General decide to produce Humvees for civilian use. They started making the models in 1992 and change the name from Humvee to Hummer. The next important chapter in the history of the Hummer took place in the year 1998. That was when AM General sold the name rights to General Motors. AM General would continue to produce the vehicles but it was GM that handled the marketing. GM was also responsible for selling the products. The Hummer would prove to be such a hit that GM would later produce other models. The original Hummer was renamed H1 while the newer models were called H2 and H3 respectively. The...
Who Invented the Pythagorean Theorem?

Who Invented the Pythagorean Theorem?...

It is said generally that the Pythagorean Theorem was invented by a Greek named Pythagoras. Obviously it was named after him and is said to have been discovered or invented by the year 530 BC. However, researchers have found proof that even though documents do date and trace back to him but the theory itself might have existed a lot earlier than we might have believed. Background on Pythagoras Very little is known about the early years of Pythagoras who lived from 569 to 500 B.C.E. He was born on Samos Island in Greece. Since the theory is named after him it is assumed that he is its inventor. However, it is known that he spent a lot of his time traveling all through Egypt. He spent learning a lot of things in his travel there especially about mathematics. His famed status came about when he formed the Brotherhood of Pythagoreans. The group was dedicated to the learning and study of mathematics. Like a lot of ancient groups it became a bit more cultic inculcating rituals, prayers, and symbols. They even gave numerical values to many thoughts, ideas, and objects. It was also believed that such values were endued with mystical qualities. After completing the Pythagorean Theorem, as legend puts it, Pythagoras then proceeded to sacrifice 100 oxen. He also wrote plenty of geometric proofs. However, since his founded group also had a shade of secrecy it became quite hard to figure out who the actual authors were. Date of the Pythagorean Theorem He, Pythagoras, is credited for the authorship of the Pythagorean Theorem; however it is not really possible to really tell if he really was its author. The rudiments of the theory can also be found in...
Who Invented Gingerbread Men?

Who Invented Gingerbread Men?...

One can say that the person who invented gingerbread men actually influenced a lasting love of many people towards sweet stuff and biscuit or cookie moulds. The Legend of the Gingerbread Men Many say that it was Queen Elizabeth I who invented gingerbread men. This respected queen of England was said to have the first gingerbread men made into the image of the queen’s courtiers. This was done as such so it could serve as small gifts to be given to them. Some say that this is merely a myth. Others say it is reality. Other Interesting Notes on Gingerbread Men After that first batch of delicious gingerbread men, it was said that the English went to America and brought ginger with them to the USA colonies. And, perhaps, you can say that this delicious sweet treat spread throughout the land. There were even some accounts that mentioned the use of ginger cookies as a means of persuasion to voters in Virginia. This was given to the people so they, in turn, would elect the candidates that would be working in the House of Burgesses. Perhaps, because the use of gingerbread men became more famous, the brothers Grimm soon wrote the fairy tale, Hansel and Gretel, which modernized the use of gingerbread. This story was written and published during the 19th century. Pertinent Information to Bear in Mind There are a few things to learn if you’re going to think of making gingerbread men. The term “ginger” is actually taken from the Sanskrit word “srngaveram” meaning “horn root.” In the olden days, particularly, in Medieval England, the term gingerbread came from the Old French word “gingebras” which, in turn, was taken from the Latin term “zingebar.” Gingerbread meant “preserved...
Who Invented the X Ray?

Who Invented the X Ray?

X Ray is a kind of electromagnetic and ionizing radiation that has shorter wavelength as compared to the ultraviolet ray. This radiation is very useful for crystallography as well as diagnostic radiography. Because of the functions of the electromagnetic radiation, the term is commonly used to refer to an image that can be created using diagnostic radiography. The X Ray is helpful in identifying various medical conditions so it is best that we recognize the people behind the development of this diagnostic technique. History Who invented the X Ray? X Ray was invented by several scientists who examined cathode rays in 1875. The scientists involved in this special project were Wilhelm Rontgen, Philip Lennard and Johann Hittorf. Rontgen is a physics professor in Germany who studied the electromagnetic rays produced by Crookes tubes. He published a paper about his discovery on December 28, 1895. He called the ray as X since it is still unknown. Rontgen received a Nobel Prize in Physics for his invention. Lennard and Hittorf both work with Rontgen in the analysis of cathode rays. Hittorf found that there would be flawed shadows when unexposed photographic plates were placed near the Crookes tubes. However, Hittorf did not investigate the shadows. Additional Information and Other Important Details Other important personalities in the invention of X Ray Ivan Pulyui, Nikola Tesla, Fernando Sanford as well as Thomas Edison. Pulyui was an experimental physics professor at the Prague Polytechnic. Several weeks the publication of Rontgen’s paper on the X ray photograph, Pulyui published a report in journals about high quality X Ray photographs in London as well as in Paris. Tesla created a special and effective single electrode X Ray tube. He published a paper about his invention in...
