Talk to me

Description

Description:

It is normal for us to use the speech recognition of our mobile phones when we want to find out the fastest way home. But actually, recognizing our language correctly, is not an easy task for a computer. When we speak, we blend multiple letters to a sound or make no pauses between the words. Each one of us also speaks differently due to our own accent or dialect. “Talk to me” shows us the processes necessary in the background for a machine to recognize our speech. Its neural network was trained with hundreds of hours of voice recordings in English and German in order to be able to detect every letter as correctly as possible.

Bouteilles et océanographie

Submitted by Christine Leininger on ven, 12/21/2012 - 13:53

Nous allons nous intéresser au processus élémentaire qui est à l’origine de la mise en mouvement de gigantesques masses d’eau. Nous verrons que tout repose sur leur différence de masse volumique. Ceci peut être expliqué mathématiquement, et illustré grâce à des simulations réalisées par ordinateur ou à une expérience réalisable par tous, à l’aide de bouteilles plastiques, de pailles et de sirops alimentaires… Pour plus de détails, voir http://interstices.info/circulation-oceanique La version française de la vidéo est visible ici.

IMAGINARY in Springer Book

Submitted by Andreas Daniel Matt on mar, 09/11/2012 - 10:27

IMAGINARY is part of the new book “Raising Public Awareness of Mathematics” by Springer: in the article “Mathematics Between Research, Applications, and Communication” by Gert-Martin Greuel and in the article “IMAGINARY and the Open Source Math Exhibition Platform” by Andreas Matt. It is also mentioned in several articles, as for example in the article on the website mathematik.de or in the article on the German Year of Mathematics. In the book you will find an exhaustive case study and many ideas on how to communicate maths to a broad public! More info at the Springer page.

Algebraic Surfaces

Submitted by Torolf Sauermann on lun, 04/22/2013 - 09:28

I started playing with algebraic surfaces in the German Year of Mathematics 2008. This gallery shows a few results playing with the program SURFER.

Genomics Youth Camp in Karachi

Submitted by Elisabeth Schaber on mar, 11/14/2023 - 10:12

The camp aims to explore the convergence of Genomics, Mathematics, and German language skills. Participants have the opportunity to engage in hands-on activities, decoding the languages of genes, machines, and humans.

Located at the TDF MagnifiScience Centre, the camp provides a dynamic platform for young minds to delve into the world of genomics. The program highlights the importance of interdisciplinary learning, emphasizing the relationship between Genomics, Mathematics, and linguistic skills. The camp concluded with participants presenting their final projects, showcasing the knowledge and insights gained over the three days.

SURFER in Leipzig

Submitted by IMAGINARY on lun, 02/10/2014 - 15:11

LGM2014 takes place on April 2-5 in Leipzig, Germany, and will feature workshops for artists and ca. 90 inspiring talks to showcase new and upcoming projects such as Tupi, Kune, Synfig, Laidout, as well as established projects such as GIMP, Krita, Inkscape, Scribus, and Blender.

Since 2006, the Libre Graphics Meeting is the primary event where developers of free software for artists meet to work on common goals. LGM is free to attend and open to all! Please let us know if you are coming so we can plan ahead to welcome you.

SURFER will be introduced at the Libre Graphics Meeting. Our real-time raytracer of algebraic surfaces will be presented for the first time to the open source graphics and computer science community. The talk will be on April 2nd, at 17:00 by Christian Stussak, developer of SURFER.

Abstract of the talk: “SURFER is an open source program to visualize algebraic surfaces in real-time. It was developed for an interactive installation at the IMAGINARY exhibition for the German Year of Mathematics 2008 and was then extended and used in more than 110 exhibitions in 23 countries: for museum installations, schools and home use. The program is a bridge between art and mathematics and can be used to create beautiful pictures while at the same time exploring and learning the underlying mathematics. To create an image you enter a polynomial equation, for example x^2 − x^3 + y^2 − z = 0. SURFER then immediately calculates the points in space that satisfy this equation and displays them using ray tracing and an optimized root finder. In this presentation the program is introduced with many examples.”

AI Core Concepts Workshop

The workshop is based on digital modules and analogue games and discussions: visit restaurants in a new city and understand the difference between Exploration and Exploitation, follow us on a treasure hunt via gradient descent and find strategies to always win in the Chinese Game Room. In the mood for discussions? Download the discussion game “Blickwinkel KI”!

All material of the workshop is available under an open source license. Please let us know if you re-use material for your own workshops or have any feedback to further extend the workshop content.
