Newfound powers

Oh, hai!

As I have probably mentioned at some point, some of the bands I like include Behemoth and Belphegor. Both came with new albums recently. Behemoth’s new album ‘Evangelion’ is definately different from ‘The Apostasy’, but it definately kicks at least as much ass (which is quite a lot!). Since ‘Walpurgis Rites – Hexenwahn’ from Belphegor is far more recent, I havn’t really listened to it enough to form an opinion, but there are definately things that I like here :D

Also, a few weeks ago someone mentioned something math-related. As you may know, x0 (x being any number except 0) is 1. I was told once why that was, though I couldn’t remember it and it bugged me for weeks. But I found it again (and it seems that very few people know this), so if you’re interested:

Basic rules when working with powers include that xa ยท xb can also be written as xa+b. For division, a similar rule exists which says that xa / by xb equals xa-b. Now if we take the second rule, and assume that a and b are equal, we find that xa / xa = xa-a, which is the same as 1 = x0 (which is valid as long as x does not equal zero, in which case it is undefined).

Yay!
