Learn how to count/ Aprender a contar

If you are interested in teaching Maths to the very tender, have a look at this links:

How to count from 1 to 10 (I have used it myself to fix my ideas). It has categories of games according to its recommended age:

Would you like to stop smoking? No? You don´t mind at all? I don´t believe you. Anyway, watch this BBC docummetary on smoking, etiher if you love cigarettes or if you have made up your mind about quitting:

By the way, if you didn´t know, tobacco is the main cause of preventable death.

----------------------------------------------------------------------------------------------------------
¿Le gustaría dejar de fumar? ¿No? ¿No le importa en absoluto? No me lo creo. De todas maneras vea usted este documental de la BBC sobre el tabaco, tanto si adora los cigarrillos como si ha tomado la determinación de dejarlo.

Por cierto, en caso de que no lo sepa, el tabaco es la causa de muerte prevenible más importante.

History of Maths / Historia de las matemáticas

I have come across many interestig books, links and videos on the History of Maths. For an non mathematician, this is an interesting way to look furhter into Maths, and hopefully, learn a bit more of it.

This is a video by Terry Jones (a former Monty Python) with an hilarious look into the development of Maths:

Vídeo by Terry Jones, part 1

Video by Terry Jones, part 2

And then, you have the more serious tone in the Marcus du Sautoy doccumentary:
The Language of the Universe, part 1


This is another BBC doccumentary (1986) on the development of Calculus:

Random or fixed effects?/ Efectos fijos o efectos aleatorios?

One of the decisions to be taken when performing a systematic review is whether to choose a random or fixed effects model. Very briefly, a fixed effects model is chosen if the studies in the metaanalisys are homogeneous, and random effects model is preferred otherwise. This video illustrates the question:

http://www.youtube.com/watch?v=laviboNorXk

 ---------------------------------------------------------------------------------------------------------
Una de las decisiones que hay que tomar cuando se lleva a cabo una revisión sistemática es si se debe escoger un modelo de efectos fijos o de efectos aleatorios. De manera muy resumida, se escogen efectos fijos si los estudios incluidos en el metaanálisis son homogéneos, y efectos aleatorios en caso contrario. Este vídeo ilustra la cuestión.
