Wolfram Research co-founder and author Theo Gray has made the most amazing Periodic Table table for his collection of elements! And he’s collected so many in a variety of forms over the years… liquids, solids, bottles of gases, crystals, and cheeky substitutions. What a great, hands-on way to experience what could otherwise just be a bunch of memorized letters and numbers.
