Who Invented Chalk?

Who Invented Chalk?

Your first encounter with chalk might have been in the classroom where you often see your teachers use them to write on a chalkboard. The most familiar form of chalk a lot of people have come familiar with is made of slender sticks around a quarter of an inch thick and about three inches long. You might even have come to wonder who invented chalk. Who Invented Chalk It might come as a disappointment to find out that no one can tell who invented chalk. Chalk is readily found in nature and has been used as a tool for drawing and writing for quite a long time. Drawings that date even to the prehistoric times have been discovered by archaeologists. The earliest chalk writings/drawings have been found in caves. As time went by artists from various countries used chalk to make drawings and sketches. Their work was protected using shellac or any comparable substance. For the convenience of these artists, a major innovation was introduced – chalks shaped into sticks. Even though chalk artists can’t be credited as the ones who invented chalk, their need introduced an innovation that would last for centuries. Making Chalk In the same way we don’t know who invented chalk, we also don’t know who invented the method to make chalk into sticks. What we know is that the method starts by grinding natural chalk into a very fine powdery form. Water is then added along with clay and various color pigments depending on what color of chalk you want to make. The clay actually acts as a binder of some sort. The mixture will initially look something like putty that would be rolled and shaped into cylinders and then would be left to...
Who Invented School?

Who Invented School?

A lot of people hate school. But lots more love it. It’s been around providing educational foundation for people. Both lovers and haters of it probably wonder who invented school. Or who started the idea of school? Byzantines or Hellenists? There are some suggested answers on the Internet, but they are far from being accurate about who invented school in particular. Most of them point to the Byzantines. They were said to be the first people on earth to come up with the idea of a school system. These people continued the Roman Empire in the Middle Ages. They were heavily influenced by the Greeks, especially in language. The Greeks were so dedicated in seeking knowledge. They had been known for this long before the Byzantines thought of a school system. Thus, some say they were the ones who invented school. But what Greeks had was a form of discipleship, not a school. There was an itinerant teacher with disciples. They traveled to places. They seldom met in permanent places. They conducted lectures in different locations and some local folks sometimes joined in to listen. There was no formality. So they were not the ones who started the idea of school. The Byzantines liked the Greek idea of teaching a following, but they preferred to have it in an enclosed permanent area and with a system. The Greek philosophers and their disciples talked about anything randomly under the sun. They often sought meaning in life. The Byzantines wanted more specific subjects dealt with at a time. Like Mathematics, Language, Philosophy, Religion, History, and the like. Thus, they’re considered the people who invented school. Who’s Horace Mann? To give a specific name to answer who invented school, some mention Horace...
Who Invented Algebra?

Who Invented Algebra?

Algebra. For most of us, it is one of the banes of school life. Many see it as an adverse course, an unnecessary complication for one’s academics. It is then not rare for students to joke about their contempt for the inventor of the subject. Well, it maybe a playful joke but it does lead to an important question: who invented algebra anyway? Now, some may not pursue the thought of finding out the creator of their much-hated subject but for those who will do, it will be a fruitful exercise as it will make one realize the importance of the role that algebra played in human progress. So who invented algebra? Most of us are accustomed with inventions having a definite inventor: a single individual, like Thomas Edison for the light bulb, or a specific group of people like Chinese for gun powder. This is not the case with algebra however. Asking who invented algebra will give you the Arabs who are widely credited for the creation of the said branch of mathematics but there are also those that believe the Babylonians are the ones that must be given credit for inventing the algebra. But where does this rift concerning the question who invented algebra come from? As can be seen from the word itself, algebra, which comes from the Arabic al-jabr, one of the basic operations discussed in the influential book made by Arabs about the subject, Arabs contributed a lot to the subject. So much was their contribution that only through the translation of their works did the West learned much about algebra. The modern word that is algebra came into being only when the book was translated from Arabic into Latin by a Western scholar...
Who Invented the Pencil Sharpener?

Who Invented the Pencil Sharpener?...

A look at the history of pencil sharpeners shows that the Frenchman Bernard Lassimone was the first to get a patent for pencil sharpeners in 1828. Following his invention, other designers made improvements and refinements. The Early Pencil Sharpeners Pencils had been invented before the sharpener and people used knives to sharpen them. It was a tedious process and the result was uneven. After Lassimone’s invention, Therry des Estwaux came out with a mechanical sharpener in 1844. It took a while before the devices were accepted. But by 1865 companies were already manufacturing pencil sharpeners. A company called Eureka filed a patent for a small sharpener sometime in the mid 1860s. By the 1880s, several companies started producing them in larger numbers. One of the most well known companies in the early history of pencil sharpeners was Eagle Pencil Company in New York. A Look at Early Pencil Sharpeners From the 1880s to the early 1900s, many kinds of pencil sharpeners were developed in Europe and America. The electric sharpeners came out around 1917, but other types were produced. 1916’s New Era Pencil Sharpener resembled a plunger. The pencil would be placed inside the device and press it again and again. This process sharpened the blade. Another unique device was the Babock Duplex Pencil Sharpener. The device was patented in 1900 and came with a rotary of 6 blades. The history of pencil sharpeners shows that it was operated in the following manner. When the pencil was inserted, the blades would rotate around it. The right hand operates the crank that rotates the blade. The left hand operates the metal bar. One of the earliest sharpeners was invented by Guhl and Hurbeck in 1897 in Germany. It was called...
Who Invented the Distance Formula?

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 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...
