Abacus
The abacus is an ancient calculating tool used in many parts of the world. It consists of a frame holding parallel rods strung with movable beads in wood, stone or metal. The position and number of the beads allows the user to calculate numbers. Abaci were used for arithmetic as early as 2700 BC in Mesopotamia and ancient Egypt. Variations developed in Greece, Rome, China, Japan and Native American cultures using different bead configurations suited to their numerical systems. While replaced in most areas by modern calculators, abaci are still used educationally and by visually impaired individuals.
Abacus and its use
The abacus is one of the earliest counting devices, believed to have originated in Central Asia. It spread from there to Europe and East Asia between the 12th-13th centuries. An abacus uses a wooden or plastic frame with sliding beads to teach place value and perform calculations through visualization. Using an abacus can improve math skills, concentration, memory, observation skills and mental calculation speed through dual-brain engagement. It remains used as a learning tool in some primary schools.
Blaise pascal
Blaise Pascal fue un matemático y físico francés que realizó importantes descubrimientos e inventos a una edad temprana. A los 12 años descubrió un teorema geométrico y a los 15 inventó la Pascalina, una de las primeras calculadoras mecánicas. Más tarde formuló la ley de Pascal sobre la presión hidrostática y realizó contribuciones fundamentales a la geometría y las probabilidades.
BLAISE PASCAL
Blaise Pascal was a French mathematician, physicist, and philosopher. He was a child prodigy educated primarily by his father. Some of Pascal's key contributions included developing Pascal's triangle to express binomial coefficients, inventing the syringe and hydraulic press, and establishing Pascal's law of fluid pressure. He also made advances in probability theory and the study of cycloids. Pascal invented an early mechanical calculator called the Pascaline to aid with mathematical computations. He made many contributions to science before his early death at age 39.

Blaise Pascal fue un matemático, físico, filósofo y teólogo francés nacido en 1623. Realizó importantes contribuciones a las matemáticas y las ciencias como el diseño de calculadoras mecánicas y aportes a la teoría de probabilidad. Luego de una conversión religiosa en 1654, se dedicó a la filosofía y la teología, escribiendo obras defendiendo el cristianismo. Murió en 1662 en París.

The document discusses strategies for creating an investment portfolio based on Nobel Prize-winning academic research. It recommends structuring portfolios to take advantage of factors like company size, relative price, and profitability that have been shown to increase returns. Specifically, it suggests investing more in small and value stocks, as both have higher returns than large or growth stocks over the long run. The document also provides examples of model portfolios that diversify across global stock and bond index funds targeting these factors.
History Of Computer
As early as the 17th century, mathematicians were working to build machines that could perform basic math functions like addition and multiplication. In 1804, Charles Babbage designed the difference engine, an early general purpose computer with a mechanical memory. Generations of computers are defined by their underlying technology: first used vacuum tubes (1940s), second used transistors (1950s), third used integrated circuits (1960s), fourth used microprocessors (1970s), and fifth aims to use artificial intelligence, with some applications like voice recognition in use today.

Since ancient times, humans have worked to develop tools to help with tasks like counting and calculations. The abacus, invented over 4,000 years ago in China, was one of the earliest counting devices, allowing easier addition and subtraction. Later inventions included Pascal's calculator in 1642, the first mechanical calculator; Leibniz's calculator in 1673, which could also multiply and find square roots; and Jacquard's loom in 1801, which used punch cards to automate patterns in textile production. These early electromechanical devices paved the way for computers.
What is computer
The document discusses the history and evolution of computers from ancient counting devices like the abacus to modern digital computers. It begins with early mechanical calculators invented by Pascal and Leibniz in the 1600s. Important developments include Babbage's analytical engine design in the 1830s, Hollerith's tabulating machine used for the 1890 US Census, and the first programmable digital computer, the Harvard Mark I, built in 1944. The document then covers the five generations of computers from vacuum tube-based machines to today's portable devices and discusses different types of computers like mainframes, supercomputers, and analog versus digital systems.

Evolution / history of Computer
Early computing devices included the abacus invented over 5,000 years ago in China. In the 17th century, John Napier invented Napier's Bones, a device for multiplication, and Blaise Pascal created the Pascaline calculator for addition and subtraction. In the 19th century, Charles Babbage designed the Difference Engine and Analytical Engine, considered the first programmable computer. The Analytical Engine concept formed the basis for modern computers. In the 20th century, Howard Aiken invented the Mark 1, the first electronic computer, while ENIAC, completed in 1946, was the first general-purpose electronic digital computer.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
