Who Invented the Distance Formula?...

The man who invented the distance formula must have been amazed by distances. And why not? He was a traveler. He was a scientist and a philosopher always seeking the meaning in life. Aside from being educated in Greece, the distance formula inventor traveled other parts of the world to learn from other civilizations. Pythagoras Many acknowledge that Pythagoras was the person who invented the distance formula. He was from Samos and born around 570 B.C. He traveled not just to Egypt and Babylon, but also to Arabia, Phoenicia, Judea, and India. He did this in search of knowledge. According to records, he was much amazed by what knowledge was available in Egypt. He was also fond of experimenting with numbers and later on ended up being the distance formula inventor. Pythagorean Theorem Vertical, horizontal, or diagonal distance can be solved using Pythagoras distance formula, or what is called “Pythagorean theorem.” The man who invented the distance formula based this on the dimensions of a right triangle or a 90 degree triangle. This triangle has three sides—the base, the height, and the hypotenuse, which is the diagonal side. If 2 sides have known dimensions the third unknown can be solved. Thus, to solve the distance from one point to a standing structure, and the dimensions for the structure height and the hypotenuse are given, the distance can be calculated. The formula for this is C squared is equal to A squared plus B squared. According to the distance formula inventor, C is the value for the base, A is the value for the height, and B is the value for the hypotenuse side. The man who invented the distance formula figured any unknown value of this equation can be...
Who Invented Boolean Logic?

Who Invented Boolean Logic?...

The Boolean logic (also known as Boolean algebra) is an efficient logic operations system that is very useful in studying various fields like computer science, electronics and digital electronics. The system became more popular when Claude Shannon used electric circuits and relays as an analogy for the Boolean algebra. Before we proceed with the applications of the system in search engine queries, database and digital electronic circuit design, it is best to know the person behind the invention of the Boolean logic. Historical Background of the System Who invented Boolean logic? Mathematician George Boole invented the logic operations system in the mid 1800s. He incorporated logic to the basic concepts of mathematics and determined the base information of Boolean algebra. His invention of the system was published in the paper that he released in 1847 entitled “The Mathematical Analysis of Logic.” The system played an essential role in the development of binary system by Claude Shannon, which became significant to computer science. Additional Information and Other Important Details There are three operators that are significant to the logic operations system, which are the ‘and,’ ‘or’ and not. The first operator is defined by the dot symbol. On the other hand, the second operator is defined by the plus sign. Finally, the third operator is defined by A with a line on top of the letter. In addition to operators, Boolean logic has properties that are similar with the usual set logic. Some of the properties associated with this logic operations system are associativity, commutativity, absorption and distributivity. The other properties of the system are complements, idempotency, boundedness, 0 and 1 are complements, de Morgan’s laws as well as involution. This special operations system is widely used in the field...
Who Invented the Chalkboard?

Who Invented the Chalkboard?...

Mr. James Pillans is regarded as the inventor of the chalkboard (or blackboard). He was the Headmaster of a high school in Edinburgh, Scotland. However, the experts on the history of the chalkboard aren’t sure when he invented it. Blackboard and Chalkboard The word chalkboard is used mainly in the United States. It started to be used around 1935-40. In other countries and regions, blackboard is the term employed. The word blackboard has been in use for a much longer period. Records show it was being utilized as far back as 1815. Spread of the Chalkboard Exactly how Pillans conceived of the chalkboard isn’t clear. But it’s known he was using it to teach geography in the school and that he was using a chalk. The device was first employed in the US in 1801. A teacher at West Point named George Baron used the chalkboard for his math class. However the history of the chalkboard began, its use became widespread. This is understandable. Prior to 1801, teachers couldn’t present their concepts and ideas in a visual manner. In most classes, students employed slates. The material was made of wood and covered with black grit. Other slates were made of porcelain. It was where students used to write their lessons. Because there were no chalkboards, the teaching process was tedious. If a teacher wanted the students to solve a math equation, they would go to every student. The instructor would write the math problem on the slate. To make matters worse, not all students had slates. The first school in California was inaugurated in 1846. Because the students and teachers didn’t have slates, the students had to write their answers on their hands. As the history of the chalkboard...
Who Invented the Piano?

Who Invented the Piano?

One of the highly popular musical instruments, the piano is versatile enough to be used as an accompaniment, as part of chamber music as well as ensembles. Aside from these interesting qualities, there are much more to learn about it including its history. To understand the historical aspect of this important musical instrument further, it is good to know who invented the piano. The Invention of the Piano Who invented the Piano? Bartolomeo Cristofori , who was once a maker of musical instruments in Italy, was credited for the invention of the modern piano. He lived from 1655 to 1731. He developed the instrument some time in the 18th century, when he worked as the Keeper of Instruments for Prince Ferdinand Medici. Furthermore, he perfected the complicated mechanical aspects of the piano design. Aside from this, he was also credited for inventing other instruments, particularly the oval spinet and the spinettone. Additional Facts and Other Interesting Details Until now, three of the original pianos created by Cristofori are in existence, all of which dates back as far as the 1720s. The first one is dated 1720, which is currently found in New York, particularly at the Metropolitan Museum. The second one is dated 1722, which is in Rome, specifically at the Museo Nazionale degli Strumenti Musicali. The third one dates back to 1726, which is situated at Leipzig University’s Musikinstrumenten-Museum in Germany. The different types of piano include the grand piano, the upright piano, the studio piano and the console piano. The grand piano is characterized by the horizontal arrangement of strings and frame. Meanwhile, the upright piano is also referred to as the vertical piano, which is more compact in terms of design. The studio piano is known...

Who Invented the Pen?

Introduction The ability to write is one of those things that men believe sets them apart from animals. It is also one of the oldest. Archeologists have found cave drawings from the time of primitive humans. These were made with sharpened rocks, the first writing instruments. Early Writing Early Pens The Greeks invented the first writing instrument that resembled a pen. It was a sharp-pointed object called a stylus made of either bone or metal. They would use it to make marks on a wax-covered writing tablets. Since wax is vulnerable to scratches, they designed the tablets to fold in the middle to preserve the writing. So they looked like the earliest notebooks and journals too. In Rome, they used bamboo sticks for writing pens. They would fill it from one end with ink and the other end was sharpened for writing. The Chinese invented “india ink.” It was first used to paint hieroglyphs on stone. India ink was made from oil, soot and animal substances. Other peoples were making their own writing inks from various plants and minerals too. At the same time people were learning to make writing paper. While the Chinese used wood fiber, the Egyptians, Greeks and Romans used parchment and papyrus. In 700 AD, the well-known quill pen came into use. It was made from the feathers of live birds, usually goose or (more expensive) swan. The quill pen was hard to make and had to be replaced each week. The Modern Pen In 1884, a thousand years after the advent of the quill pen, Lewis Waterman invented the first modern fountain pen. Waterman was an insurance broker in New York. One of his clients was about to sign on to a lucrative contract...

Who Invented Astrology?

The Age of the Early Babylonians If you would check out the historical records of astrology, you would probably see that the people who invented astrology are the Babylonians. This belief is supported by earliest pieces of astrological documents such as the Enuma Anu Enlil. This particular document is said to have been written during the early 1600 B.C., and holds an enumeration of astronomical omens and the respective interpretations for each. Babylonian Astrology was used mainly for prediction of certain events like famine, war, o meteorological circumstances. Aside from that, a main concern was also about the king’s fate. Thus, those who know astrology during that time would be employed by the king, and act as personal advisers. Another piece of history during that time points to around 400 B.C. when this group of people was believed to have started calculating and making a mathematical means to be used in astronomical prediction. Later, this early system, which was recorded on clay tablets, was disseminated to India and the whole of Middle East. The system proved helpful for the Babylonians in their attempts to read natal horoscopes and make their predictions. The Era of Greek Astrology If we are going to talk of the original creators of horoscopic astrology, what would come to mind would be the work of the Greeks. According to history, they get the credit for creating horoscopic astrology that was greatly used for natal horoscopes of people, and for providing answers to certain questions or appropriate actions to take. With the early system introduced by the Babylonians, the Greeks added their own various ideas and concepts. This includes the concepts of various signs in the horoscope as being male or female in nature, and the...
