New math symbols here:

The article starts off with some weird statements:

Quote:
For 70 years, mathematicians have been stuck on the Halting Problem: Computers occasionally hang on one line of code and fail to move on to the next, and no one can reliably predict when that will happen. (The result is the unending hourglass or pinwheel of death.)


WTF? See Wikipedia:

Quote:
In computability theory, the halting problem is a decision problem which can be stated as follows: given a description of a program, decide whether the program finishes running or will run forever.


It's hardly "Computers occasionally hang on one line of code and fail to move on to the next". Jeez, they ought to have writers to know what they're talking about. The first comment to the article on Wired also points out that it's bogus.

I wouldn't use this article as any basis for justifying any proposed new math characters. Wait for a real publication.

You are jumping the gun here. The purpose here is to track the fact of the invention. The article contains the name of the author and the fact that he plans to publish a book. Some of the people interested in math are already pursuing contact with the author and will track whether these make it into more rigorous publications.
