1 komentar:

  1. Hey, guy, hello! I'm brazilian, and I had a lesson about colummn cromatography this week. Speaking of which, take a look at my post, originally in Portuguese, which I would like to give a first lesson in physics and chemistry to children who have never seen it. And while I criticized the Brazilian educational system. I'm curious to read the opinion of someone from outside the country. Leave a comment!
