So next week there will be two minor celebrations. One on Tuesday and one on Thursday. So it's going to be a very festive week. And people blast through it. It's one mark off for every error down to zero. We don't give negative scores. And people just go right through it.

People are very proud of the fact they know the S, P, and D blocks of the Periodic Table by memory.
But I don't want to neglect, disrespect the lanthanides and actinides. So we're going to have two contests. Mnemonics to help remember the names of the lanthanides and actinides. That's tricky to remember. So these are mnemonics contests. So here are some examples. Here's one, see lanthanum, cerium, praseodymium, neodymium and so on, all right?

This gigantic split infinitive. Clearly, clearly someone from industry.
