Standing on the shoulders of giants

Tomás, João and Gonçalo found in their grandfather's attic, a very old book about the History of Computers. They were very curious about that book because it seemed so old and valuable. They began to read it, but they didn't understand what was written there. They decided to ask their grandfather about the book because it looked very important and mysterious.

Sad and embarassed, he confessed that it was a legacy from his ancestors and he promised to be is guardian. In fact, that book holds an enigma and has the power to travel in time as a time machine. However, during one of his travels, their grandfather lost some letters of the riddle. The children, seeing their grandfather so sad, and curious about this whole story, filled themselves with courage and decided to help him. They promised to recover the lost letters of the riddle, and to preserve this valuable treasure.

EUCLID

(300 B.C.)

Euclid

Euclid of Alexandria was a Greek teacher, mathematician and writer, often referred to as the «Father of Geometry». Known for Euclidean Geometry and for his book «The Elements». Birth: 3rd century B. C., in Egypt Field of Study: Mathematics.

In mathematics, Euclid's algorithm is a simple and efficient method of finding the greatest common divisor (G. C. D.) between two non-zero integers. How does it works?

Complete the puzzle about Euclid's Algorithm using this button, and then answer the following question:

G.c.d. (45,20) =

20

Analyze the image carefully and then order the steps below in the right way.

Calculate the G.D.C. (45, 25) using Euclid's Algorithm

G.C.D. (45, 25) = 5

A. Divide the dividend by the remainder until the remainder equals 0 (zero)

Muhammad ibn Musa Al-Khwārizmī

(780-850)

Muhammad ibn Musa Al-Khwārizmī

Muhammad ibn Musa al-Khwãrazmi (780-850) was a versatile man recognized as a Muslim mathematician, astronomer, astrologer, geographer and author. In the field of mathematics, he dedicated himself mainly to the development of algebra, being considered by many the founder of Algebra. The radical of digits and algorithm come from algoritmi, which represents the Latin form of his name.

Watch the following video to learn more about the genius who coined the word algorithm.

Select in the map the country in which the mathematician Al-Khwārizmī was born.

TAl-Khwārizmī is famous for his mathematical works, which introduced Hindu-Arabic numerals and algebra to European mathematicians. As a matter of fact, the words «algorithm» and «algebra» come from his name and the title of one of his works, respectively. He introduced Hindu-Arabic numerals which eventually replaced the Roman numbers ones. Look this table and pay atention.

Through the route that the pirates followed to the treasure island, collect the Hindu-Arabic numerals that you find along the way. Then, convert the code into decimal numbers using the previous table, and write the answer in the TextBox:

charles babbage

(1791-1871)

charles babbage

Charles Babbage was a 19th-century British mathematician, philosopher, and inventor. He is considered one of the pioneers of computingand is often referred to as the «father of the computer».

Babbage is known for conceiving the analytical engine, a programmable mechanical device designed to perform complex calculations. It operated based on punched card instructions and was steam-powered. Choose the image of Babbage's machine in order to advance.

Ada Augusta Byron

Mathematician and writer from the 19th century. She is known for her pioneering contributions in the field of computer science. Lovelace collaborated with mathematician Charles Babbage in the development of the analytical engine,a precursor to modern computers.

Arithmetic operation of the difference engine

Observe the matrix card assigned to you. It is divided by:

• Rows (A, B, C, D, E)
• Columns (1, 2, 3, 4)

For each intersection , you will find:

• A value
• Arithmetic operations (+; -; *; /)

Example: B3 -> +50-

George Boole

(1815-1864)

George Boole

English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean Algebra, is basic to the design of digital computer circuits. Boole drew an analogy between algebraic symbols and those representing logic, thus initiating the algebra of logic, which later became essential for the evolution of computers. The data type «Boolean» is widely used in modern computer languages.

SEYMOUR PAPERT

(1928-2016)

Seymour Papert

Seymour Papert, whose career traversed a trio of influential movements — child development, artificial intelligence, and educational technologies — was among the first to recognize the revolutionary potential of computers in education. In the late 1960s, Papert came up with the idea for Logo, the first programming language for children. Children used Logo to program the movements of a «turtle» — either in the form of a small mechanical robot or a graphic object on the computer screen.

Edsger Dijkstra

(1930-2022)

Edsger Dijkstra

Dutch mathematician and computer scientist, born in Rotterdam (1930) and died in Nuenen (2002), aged 72. Dijkstra is known for his contributions to graph theory and for having developed in 1959 the famous «Dijkstra algorithm». This algorithm is used to find the shortest path between two points in a graph, where edges have an associated cost.

Dijkstra's shortest path algorithm is widely used in applications that require route planning, such as GPS navigation systems, transport networks, logistics, among others.

Dijkstra's algorithm

Analyze the image and indicate how many paths there are between point 1 and point 7, without going through the same point twice.
