Powers of ten

Good evening kids, 

I post here a video that I found very cool to explain the powers of 10 and the different orders of magnitude. This is called "Powers of ten". I was recommended by my friend Brianda, who is an architect. The film was made ​​in 1977 by a very famous couple of designers: Charles and Ray Eames.


Have fun.

2048

Chic@s, en esta tarde de viernes de poca luz y amenaza de lluvia igual os apetece jugar a un juego on-line sobre potencias de dos. Es muy friki, no os enganchéis.

JUEGO

Ya me contáis hasta qué número llegáis, yo no paso de 512.

Buen fin de semana

Día de PI

Buenas tardes,

el viernes os conté que era el día de PI. Ya hemos tratado el tema anteriormente en el blog (2011 y 2013).

Hoy os dejo un gif en el que se ve cómo se va aproximando el perímetro de un polígono de n lados al de la circunferencia circunscrita. Espero que os guste.

Ver GIF.

Un saludo
ALICIA
