Interesting Popular Science Articles in English
I'm excited to recommend Science Niblets , an on-line magazine that a friend of mine writes and edits. The articles there will interest intermediate English learners and fluent native speakers alike with topics such as the physics of a curveball and solar powered electricity. Incidentally, Elmar, the author of the website is an extremely proficient second language speaker of English. His level of bilingualism and his writing skills are an inspiration to me as a language learner and teacher! Not to mention I find his articles really useful for my students!
