EXPLANATION:
- The ancient Egyptians were the first to develop the pen as a basic writing instrument. The oldest papyrus piece was written in 2000 BC. This proof suggests ancient Egyptians were the first to build a tool which would allow them to make their language permanent. The quill pen was used for the longest time in history-from the 7th to the 19th century-among all the writing instruments. Bird feathers were used by Europeans to build this method.
- The best feathers were from live turkeys, geese, and swans. The reign of the quill finished with the development of a mass-produced steel point stylo by John Mitchell from Birmingham. These were still ink pen and worked in the same way as quills, but were robust and far cheaper than quills. The discomfort in which a pen has to continue to fill its supply of ink drove the conception of the fountain pen that holds in a reservoir and leads it to the nib. It was the first Romanian inventor Petrache Poenarus who in 1827 was awarded a patent on the invention of the first ink barrel fountain pen.
- The three-channel tin fountain stalk was patented and created in 1884 by Lewis Edson Waterman. The model ensured a smooth written stream of ink and turned a plumb into a portable device. The ballpoint pen was a shift in the development of the pen, which takes us up to today. It was a lasting and relaxed writing style which could write on wood, carton and even underwater. This was a breakthrough in the 19th century that essentially ended the era of the writing of using ink.
- Lazlo was granted a new patent in 1943 with his son Georg, a pharmacist. The Biro stallions-now a household name synonymous with a ballpoint stallion-were also their first business models. Then the UK administration would purchase the pens ' rights so that the Royal Air Force crews can use them. They favored the ball point pen because it was robust and, unlike the fountain pen, it could write in higher altitudes.
- The Biro was so effective in the RAF that the military used it to the point of its still current popularity. The new felt-tipped style created by the Yukio Hore is also a major development. These styles are used in several creative environs and they are well-known for their capacity to write on many surfaces-these have even become permanent markers or are suitable for specific surfaces such as CDs .

Answer:
My favourite subject is Mathematics. The study of Mathematics began with Pythagoras, and he coined the term 'Mathematics.' Mathematics has been fundamental to advances in science, engineering, and philosophy. It has evolved from simple counting, measurement and calculation, and the systematic study of the shapes and motions of physical objects, through the application of abstraction, imagination, and logic, to the broad, complex and often abstract discipline we know today.
The first surviving examples of geometrical and algebraic calculations derive from Babylon and Egypt in about 1750 BC. The Greeks were the first mathematicians to concentrate on pure mathematics, believing that all mathematical knowledge could be derived from deduction and reasoning. They laid down axioms and built theories by using geometry. They created many instruments for watching the stars or surveying the land, all built upon mathematical principles. The most ancient mathematical texts available are from Mesopotamia and Egypt.
