Mystery Mathematician "?"

Until 17th century algebra and geometry were two distinct branches of mathematics.

He was the first man who combines algebra and geometry to provide a great tool for visualizing equations with two variables.

Name this famous philosopher and mathematician.

His middle name is given to Coordinate Plane

There are different stories about how he discovered the analytic geometry. Search about them.

Introduce his findings and philosophy.

Introduce the mathematical concept and equations.

Write a few examples of his famous quotes.

He is one of the other famous mathematicians who is also a very well-known Philosopher.

Can you name others?

What do you think, why are so many philosophers also mathematicians?

Useful resources:and 2 Impossible Objects - How to make them possible?

What is an impossible object?

Do you see any impossible objects around you?

-bottles with no insides (or outsides), one-edged loops, solid ball with no fixed size.

Can you make any impossible objects by using only a piece of paper and glue?

Have you ever heard about Mobius Strip?

Who discovered it?

Watch the video and learn about the original name of the shape?

Why this shape is so special?

Repeat the same magical moves to create a four-twisted loop, a square and the hearts as you have seen in the video.

Start your loop with a single twist. Make your prediction before unravelling the pieces–how many pieces will there be after halving horizontally? Will they be all the same size? How many twists will they have? Then cut it again. Answer the same questions.

Then, search about the recycling logo. Who has designed it and when? Find out the origins of this logo.

Iconic Number of Math

It is not possible to write it as a ratio of two integers yet it is the ratio circle’s circumference to its diameter.

People have calculated the first 10 trillion digits of it, though for most purposes – such as designing a building or sending a spacecraft to Mars.
