Periodic Table Table
Ed Pegg Jr writes "Theo Gray, a co-creator of Mathematica, was originally a chemist. Needing a conference table, he created a Periodic Table using a variety of woods." It seems Theo is missing some elements for the table, in case you have any spare europium (in a proper container, of course) lying about. This isn't Theo's first piece of furniture. It looks like he has left a few spots for new elements, and it is nicely modular, in the event an element is found not to exist.
No, not those elements.
/temperature controled place to store this thing. Pieces that combine dissimaler woods don't tend to last very long due to diffrent rates of expansion/contraction when they are exposed to temperature and humidity changes. They tend to break along the seems.
I hope he has a humidity
That's why you never securely bolt down butcher-block. You just drill an oversized hole and let it float on the stand.
