WebRQ 17 - 19 A growing field of inquiry that both holds great promise and poses great risk for humans is nanotechnology, the construction of extremely small machines. Over the past couple of decades, the size that a working gear can be made has consistently become smaller. The table shows milestones along this path. WebWith the numerical example proposed by Claude Leibovici who computed the parameters of a fitted plane $\quad z=Ax+By\quad$, the fitting of the plane $\quad Z=\alpha X+\beta Y+\gamma\quad$ can be carried out thanks to the principal components method (as suggested by joriki). The theory can be found in many books.
