If are used as coordinates for the complex plane, then
Thus, the 2D metric is transformed to
I use for the metric, since always evaluates to the delta tensor, for all possible metrics. In this case, .
Aside: I’ve removed an error from my post regarding the golden matrix.
Last year I got my head scanned at CitiScan, Brisbane. A GP referred me, after a blood count, in response to my ongoing seizures. I’m told there was nothing out of the ordinary. It was all bulk-billed, and the full disc can be downloaded here.
Aside: My nose looks crooked. Also, a bottom wisdom tooth is gone. Five or six cervical vertebrae are visible. My right ear looks a little more curved than the left.
The latter is only .6 MJ at McDonald’s ($1), while the former is .8 MJ at Coles ($4). Also, a soft serve is no more fattening than a hash brown, and less than half as fattening as regular fries (1.5 MJ). Furthermore, milk is ⅓ more fattening than cola.
A McDonald’s soft serve ice cream is .6 MJ ($.5), while a Donut King (DK) flat white coffee (reg) is 1 MJ ($4.50). DK have lighter coffees, but not by much. If dieting, beware coffee shops! I assume 12 MJ/day. Coles ice cream is a cheaper source of energy, at just 22 c/MJ.
This exercise complements crunches, helping remove vertebral subluxation. I’m also cracking my thumb and crunching my jaw.
This technique is superior to my previous jaw exercise. The jaw can also be repeatedly forced by hand. I simultaneously work my hip and pinky, which can be heard cracking. I’ve also done videos on crunches and hand crunches.
