First post on my first blog. Here begins an adventure that I had been wanting to start for a long time (years).

Who am I?

Since 2018 I have been teaching Physics and Chemistry at IES Rรญa San Martรญn de Cantabria (Spain). My previous experience includes mainly research and teaching at the University of Cantabria, in particular in the branch of Physical Optics. You can learn more about me here.

Why this blog?

My main intention with this website is to provide ๐Ÿ“š Physics and Chemistry notes to my students and to anyone else who might be interested, as well as sharing ๐Ÿ‘๐Ÿผ tutorials and collect ๐Ÿ”— online resources.

I think that a blog is the perfect addition to be able to debate about news with a much more dynamic content.

What am I going to talk about on this blog?

In this blog you will find opinion articles, curiosities about science in general and posts related to my interests, which include, among others:

  • โœˆ๏ธ Travel
  • ๐ŸŽธ Music
  • ๐ŸŽฎ Video games
  • โš›๏ธ Photons

Who is this blog for?

The posts in this blog are aimed at my students and anyone else who is curious about science and/or shares any of my interests.
