I find this subject highly interesting, but I don't think that's the case. In fact, there is one key assumption here (and this is not the first time I've seen it, it's quite common) that, to me, undermines the whole idea:
Actually, no, nothing is, unless its something we created ourselves. Mathematics is a tool that we use to describe things. We define mathematics, and we do so in a way that simulates some of the structure that we see around us, and in a way that is useful to learn things about the world. That is why mathematics works so well, not because the universe is based on it.
In fact, mathematics works so well because it doesn't try to explain the "real world". It's all a construction within itself, built from premises and rules we agree on, which in turn are based on our experience with the world (and, thus, are probably useful). It's up to, say, physicists or chemists to figure out which of the tools we mathematicians have created actually applies to things (and, thus, are actually useful. We can't tell the difference ).
The universe doesn't care or calculate, it just is. But it's beautiful, nonetheless...
