Has anyone ever heard about the Periodic Cycle?
A few years back I took a chem class with a professor that wrote his own book. He made it free which was nice. In it he had this picture of the
periodic cycle and not the periodic table. Did he just make this up or has anyone else seen it before?

There are lots of ways of drawing the periodic table.

I have seen many different ways of drawing it in a magazine once. I don't remember where though.

Yep. The periodic table does go on a cylinder quite nicely.
The thing is that there are literally dozens of ways of showing the periodic table. Many of the alternative forms are good at emphasising a particular
property but at the expense of others or at the expense of general clarity.
For straight-out utility. the standard form really can't be beaten. It is standard for a reason.
I admit that I am partial the wide format. But I seldom use that in practice. The same happens to all the other alternatives ultimately. But it is fun
seeing all the different representations.
Edit.
I will add that the cycle you show is not one of the more useful representations I have seen. There is a crude spiral but otherwise no underlying
logic leading to the groupings of the elements. And those same groupings are visible in the standard table anyway.
Is a spiral any more natural, logical or accessible than the typewriter-style row by row approach that is standard and is the same pattern as ordinary
reading?
