Ah, the periodic table. Loathed by all students having to learn it during chemistry lessons at school, but loved by many more people for the amount of information it can provide. As well as showing us all the elements we currently know, the periodic table can also appear as a thing of beauty.
Over at Google Research, they have a fantastic interactive periodic table of elements for you to play around with. Want to know which elements are predominately in the human body? Or which are present in the Earth’s crust (mainly oxygen and silicon)? Using the interactive periodic table, you can! It’s pretty cool to play around with.
