No TB (now there's a thing, TB......a pain in the gut)
I'm not suggesting you're dense, just struggling with the concept of gyro's; but having seen your reaction, perhaps struggling with reality as well.
Look at what you put in your initial statement. You have quoted a part of your notes and then accused that quote as being wrong. Now I wouldn't smugly suggest that all notes are perfect, and there may well be errors in them, but logic would suppose that you would at least quote the incorrect bit of the notes to back up your argument.
Here is another thought though: your hysterical written outburst is alien to the qualities required by the very profession you are trying to enter.
Be COOOOL; Chill a bit; have a beer and then settle down to some good bedtime reading. Oh, and seperate the sensitive from the spin
