It is difficult to survive in a complicated business world without sound knowledge on economics, management, law, the ways of doing business, etc. Some top business school teaches its MBA students the knowledge, but not everyone is (indeed, only a few are) fortunate enough to enter Harvard, Stanford, or Wharton. Below is a list of top 20 movies that a business man needs to watch, some of them are even highly recommended by those business school professors. You will have a better understanding of the principles and rules of how the business world runs, it will help your career as well.

Although mathematics is not the most attractive field of study nowadays, there were some days when it was quite appealing. Millions of students and great illuminated minds dedicated their life to make discoveries that eventually improved quantity, structure, space and change – the main concepts studied by mathematics. It started as a philosophy, developed as a science and finally influenced everything, from technology and architecture to art. While most of us don’t realize it, the founding and evolution of mathematics is the main reason for the modern life we take for granted.

The Egyptian decimal system and the Mesopotamian weights and measures
While the ancient Greek civilization is considered the founder of the main principle of mathematics, archaeologists found proofs that Egyptians also developed quite an advanced decimal system. This is the earliest system that allowed indefinite counting through adding new symbols. The Egyptian hieroglyphs reveal that the system is in evidence since around 3000 BC. This innovative model influenced the Minoans’ own decimal system, a Bronze Age civilization that lived on island of Crete.
While de Egyptians early mathematicians were focused on the decimal system, the Mesopotamian scientists developed a functional weighting and measuring system sometime around 4000 BC. Sexagesimal schemes (a numeral system that has 60 as its base) were used to count slaves, animals, fish, dead animals, certain types of beer and milk products. Other innovative patterns were created to count field measurement, wheat, malt, milk and beer measurement.

Pythagoras’ findings in geometry, irrationality and the square root of two
Pythagoras of Samos was an Ionian Greek philosopher and mathematician that among other, founded a religious movement called Pythagoreanism. He lived between 570 – 495 BC, a period when he founded the most famous ancient school of mathematics. The Pythagoreans thought that mathematics is not just an advanced subject, but the base on which relies the principles of all the surrounding things. Pythagoras has commonly been given credit for discovering a great geometrical theorem that states that in a right-angled triangle area, the area of the square on the hypotenuse is equal to the areas of the squares of the other sides. Due to the secrecy that surrounded the Pythagorean School, there is no evidence that Pythagoras itself has worked on this theorem.
This theorem however, pushed Hippasus, one of the Pythagorean students, to discover the existence of irrational numbers. When trying to represent the square root of 2 as a fraction, using geometry, he proved that one cannot write the square root of 2 as a fraction, therefore this was irrational. His finding could not be accepted by his fellow Pythagoreans, therefore he was ultimately thrown overboard and drowned.
