Re: [Phys-l] explanatory and response variables (was calibration )



I don't think so. Go to Wikipedia and look up Cartesian coordinate system. Scroll down to Figure-4. That is the system as I view it. This is a right-handed system. Wiki describes the y axis as pointing away from the viewer. I described as a "forward."

If you put yourself at the origin, extend your right arm to your right and in the positive x direction, then positive y is in front of you, i.e. forward, and positive z is up. That is a right-handed system.

Hi Michael,

These are both left-handed coordinate systems.

For a standard right-hand system I generally say the x-axis runs left to
right (right positive), the y-axis runs backward to forward (forward
positive), and the z-axis runs bottom to top (top positive).

In textbooks we often see x to the right, y pointing up, and z pointing
backwards.
