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...

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.

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 Astrology?

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...
Who Invented the Pencil?

Who Invented the Pencil?...

Some kids would say in jest that Mr. Pencil invented the pencil. However, to correctly answer inquisitive young minds who keep wondering who invented the pencil, here are some facts. The First Pencil Was a Failure The first attempt to invent a pencil was not successful. It was made of powdered or pulverized graphite. The result was a poor quality pencil that easily broke. Graphite and clay should be mixed well to produce a proper kind of pencil. This was done by the man who invented the pencil properly. All quality pencil makers today, owe it to the first pencil maker who perfected the right formula for it. A French Army Officer Invented it In 1795, a French officer belonging to the army of Napoleon invented and patented the first quality pencil on earth. Nicholas Jacques Conte or simply NJ Conte discovered that ground graphite, when mixed with the right kinds of clay, produced the best lead for pencils. Pencils do not really contain lead. The black thin material in pencils is a mix of graphite, carbon, and clay. NJ Conte, the first pencil maker, turned graphite into powder. Then he mixed it with moist doughs of clay and pressed the thing to make thin sticks. He then cooked it in a kiln. This man who invented the pencil, outdid his German counterparts. Faber Pencils Later, the Faber family took it from there and produced quality pencils using the Conte formula. The same formula is used worldwide today. The writing implement was not named after NJ Conte. It was taken from the Latin word, “pencillus”. It means “little tail”, probably referring to the pointed lead tip. In those times, pencillus was used to refer to fine, pointed brushes before...
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...
