The Coriolis effect is the effect that causes wind and water and moving objects to curve clockwise in the northen hemisphere and anticlockwise in the southern hemisphere, so how to determine my latitude, longitude precisely using the Coriolis effect. If I have a yo yo, a pen, and a compass, how can I determine my position?

2$\begingroup$ You could, theoretically, determine your latitude with the Coriolis effect, but it is independent of longitude. $\endgroup$– CuriousOneCommented Jul 2, 2016 at 23:25

$\begingroup$ ok then , how to determine the latitude or my position generally ? $\endgroup$– Sandy DanialCommented Jul 2, 2016 at 23:30

1$\begingroup$ How about a Foucault pendulum: en.wikipedia.org/wiki/Foucault_pendulum. $\endgroup$– CuriousOneCommented Jul 2, 2016 at 23:31

1$\begingroup$ That is a good way of measuring your latitude, there is no way of getting your longitude with Coriolis. $\endgroup$– CuriousOneCommented Jul 2, 2016 at 23:40

1$\begingroup$ A Foucault pendulum does measures the Coriolis force $\endgroup$– dmckee --- ex-moderator kittenCommented Jul 2, 2016 at 23:52

Use a Focault Pendulum, measure the rotation period of the plane of oscillation and compare it with the theoretical value $$T=\frac{24\, h}{|\sin\lambda|},$$ where $\lambda$ is the latitude. If the precession is clockwise you are in the northern hemisphere, otherwise you are in the southern hemisphere. No precession means you are at the equator line.

$\begingroup$ i don't get it , is there any way using the coriolis effect ? $\endgroup$ Commented Jul 2, 2016 at 23:38

3$\begingroup$ The Coriolis effect is what makes the Focault Pendulum to rotate its plane of oscillation. $\endgroup$ Commented Jul 2, 2016 at 23:40

$\begingroup$ so if the pendulum moves clockwise i'm in the northern hemisphere and anticlockwise then i'm in the southern hemisphere and when am i at the equator line ? $\endgroup$ Commented Jul 2, 2016 at 23:43
