Hello read.cash friends. Sorry I haven't posted for a while. I've been doing a lot of work for my Youtube channel https://www.youtube.com/mathsvideosforweb and Instagram page https://www.instagram.com/mathematics.proofs/. My schedule is crazy busy. I will be back online though with more math articles and social media tips. If you're interested in cutting edge physics and mathematics art, you can always follow me at https://www.instagram.com/tiago_hands/.
