Study Notes
Early Computing Civilizations
- Babylonians: Used clay tablets with mathematical tables (2000-500 BC)
- Developed a numerical system based on symbols for 1 and 10, which were combined to represent other numbers.
- Used counting boards similar to abacuses for basic calculations
- Egyptians: Used practical mathematics for timekeeping, land measurement, and taxation.
- Employed a base-10 number system with specific symbols for different powers of ten.
- Developed the Rhind Papyrus, which contained examples of different arithmetic and geometry problems.
Greek Contributions
- Pythagoras and Thales made significant contributions to geometry around 500-600 BC.
- Pythagoras studied Egyptian mathematics and established the Pythagorean theorem.
- Pythagoreans believed in the importance of numbers in all things.
- Thales' theorem in Euclidean geometry states if A, B, and C are points on a circle where AC is a diameter, then angle ABC is a right angle.
Roman Numerals
- Romans used a system of letters to represent numbers.
- Roman numerals were challenging to use and, often, the abacus was used for calculation.
- Roman numerals are still used in certain contexts today (clocks, cornerstones, etc.).
Islamic Influence
- Islamic mathematicians expanded on Greek accomplishments in algebra.
- Developed a comprehensive theory utilizing rational and irrational numbers, moving away from solely geometric focus.
- Islamic scholars applied algebra to arithmetic and geometry.
Notable Figures in Computing
- Wilhelm Gottfried Leibniz (Step Reckoner): Developed a calculating machine capable of addition, subtraction, multiplication, division, and square roots.
- Charles Babbage (Difference Engine): Designed a machine to produce accurate mathematical tables, an early attempt at a general-purpose computer. Recognized the potential limitations of the Pascaline, focusing on adding more advanced calculations.
- George Boole (Symbolic Logic): Developed Boolean algebra, a fundamental concept in computer logic and digital circuit design. Developed a mathematical model for switching theory. His work on symbolic logic impacted the mathematical model needed for digital circuit design.
- Grace Brewster Murray Hopper: Pioneered the development of the COBOL programming language.
- Katherine Johnson: A "human computer" at NASA whose calculations were vital for space missions.
- Gladys Mae West: Made significant contributions to the creation of a geodetic model of Earth critical to GPS development.
