The analogy of karate kata to compressed computer files (e.g. winzip files, or stuffit for Mac people*) is well known. One of our students made an interesting observation tonight; and he wasn't even thinking about zip files at all....
He said that "if you corrupt one part of a kata, the whole lot breaks down".
Nice one, Robert!
He's right, and if we compare it to a zip file it is easy to understand that if the file becomes corrupted you can't open it up to view the contents. Files can be corrupted if the computer memory (OK, hard disk) becomes damaged, or if there's a problem in transmitting the information in the first place.
Just like kata.
Another reason for not being able to read a zip file is if you don't have the software to read it. Again, it's the same for kata.
*unix and linux people have many compressed file formats, plus they are big boys and girls and don't need to be told these things.
