8:25 PM | Transparencias y vídeo de "Problemas matemáticos sin resolver que cualquier niño puede entender"
En mi opinión, uno de los motivos de la falta de interés por las matemáticas es que tienen la imagen de ser una ciencia inerte, sin nada por descubrir. Algo así como una lengua muerta. Por eso, con esta charla pretendo hacer llegar a todos los públicos el mensaje de que las matemáticas están muy vivas, mostrando tres problemas de investigación que cualquier niño puede entender.

10:10 AM | What’s the difference between accuracy and precision? - Matt Anticole
When we measure things, most people are only worried about how accurate, or how close to the actual value, they are. Looking at the process of measurement more carefully, you will see that there is another important consideration: precision.

7:17 AM | Music and Mathematics
During the Baroque period, a mathematical breakthrough inspired Johann Sebastian Bach, to write The Well-Tempered Clavier (1722), his book of preludes and fugues in all 24 major and minor keys. Bach was able to write in every key so successfully because mathematicians found better ways to calculate the 12th root of two.
