i cant explain harmonics but heres how to do them:

you have to touch all six strings with one finger at the 7th or 12th fret,right over the fret. strum and you should get a hum sound.
and i dunno what octaves are.

I can cover octaves for ya.
In any key signature you'll have 8 notes. There are only seven different notes, the first and last will be the same. The distance between these notes is called an octave.
Watch. Heres a C major scale; C D E F G A B C. The first and last notes are the same, and the distance between them is an octave. Get it. Got it. Good.

As for harmonics, dont quote me on this, but as I understand, a harmonic is like when only a section of a string is vibrated, instead of the whole length. You have to lightly touch the sting at certain points right over the frets and you'll get a smooth, ringing, bell like tone. Try over the 12, 7 and 5 frets and you'll get the idea.

In technical terms, a harmonic is a partial of a waveform that's a multiple of the fundamental frequency.

To simplify that a bit, your guitar sound is not a pure sinewave. It's made up of many different frequencies. The pitch of the note that you hear is the fundamental frequency. There are then additional components of the sound at double that frequency (the second harmonic), triple it (third harmonic), 4 times it (4th harmonic), 5 times it and so on. Those are the harmonics.

The second harmonic is an octave above the basic pitch of the note (octave up = double the frequency).

When you "play harmonics" on the guitar, you're restricting the vibration of the string. Normally, the fundamental frequency is created when the entire string vibrates up and down in sync along its length. The higher harmonics are also present, and if you lightly touch the string over the 12th fret (for instance), you're preventing the normal fundamental frequency from occuring.

If you want a decent book that covers this kind of thing, plus acoustics and much more (every musician should really have a decent understanding of the subjects), I'd suggest The Science of Sound (Rossing). You can get it from Amazon. It also covers psychoacoustics, instrument design, signal processing and much more.
