Shall we watch a movie?

This week, Topla immerses you in the world of cinema:

His freeze frames are done to the nearest millimeter...

Its image in 16/9...

Its 28mm film...

Cinema is technique with numbers and geometry everywhere!

Cinema is also films that have resonated throughout the world and that talk about maths!

Topla pampers you with a discovery of the mathematical tools that make cinema today, and a new test : “which mathematical film are you going to watch this weekend?” Are you ready for an immersion in the 7th art?

You've probably wondered how 3D can make you travel so far just by staring at a screen? Or how the special effects are so real that they make you jump in your seats?

Did you admire Benedict Cumberbatch in “The Imitation Game” and rack your brains with Russell Crowe in “A Beautiful Mind”?

So, discover this week the magical world of mathematics in the cinema…

Technical math for magical movies....

10 years ago, in 1996, Toy Story was released, which your children may still watch today. It was the first feature film to be made 100% in computer-generated images!

These computer-generated images use many geometric concepts by stretching and modeling shapes. The lighting used to make these shapes as realistic as possible is made possible by graphics software containing mathematical models that simulate the behavior of light.

You probably remember in 2009, the success of Avatar and its breathtaking 3D sequences. But how does it work? To create 3D images, the camera films 2 images instead of only one: one for the right eye and one for the left eye. These two images must be spaced about 7 cm apart: the distance between the eyes. Thanks to maths, the impression of reality is definitely there!

Test: Which math-themed movie will you watch this weekend?
(Because your love of math can also be combined with your second passion!)

You are rather sentimental:

Nathan's World (2015): This is the story of a young autistic boy, a bit antisocial but a prodigy in mathematics. His teacher Mr. Humpfrey will push him to participate in the Math Olympiad and his life will take a new turn.

You are more of a historian:

Imitation Game (2015): In the middle of World War II, Alan Turing, a mathematical genius, is tasked by the British government with uncovering the secret of the German encryption machine: Enigma.

You are rather intrepid:

Mobiüs (2013): This thriller with Jean Dujardin and Cécile de France will immerse you in the world of financial maths and secret services.

You are more of an economist:

A Beautiful Mind (2002) : John Forbes Nash, a brilliant student of Priceton, develops game theory. His work does not go unnoticed; William Parcher, a representative of the Department of Defense, offers him a position in the American secret service.

You're none of these things, and you still hate math:

How I Hated Math (2013): This documentary should convince you that math is everywhere: from Apple to Goldman Sachs; how it has changed the world for better and for worse.

And if you still want more, other ideas for movies about mathematics are here

So who said that cinema and mathematics don't go well together?
