Jam a stick in the ground aligned with the earth's axis and take your bearing from the shadow's direction. Then follow GP's instructions. Never mind that we've reinvented the sundial...
- eru 6mo ago> Jam a stick in the ground aligned with the earth's axis [...] You mean place a stick flat on the ground? (Singapore is pretty much on the equator.)
- marginalia_nu 6mo agoThe closer you are to the equator, the taller the stick needs to be. If you're really close, the height requirements diverge, and the stick is at this point technically more of a space elevator[1] than a stick. But don't lose hope, just tell Bezos that Musk wants to fund your space elevator, and vice versa, to goad one of them into funding your $10tn near-equatorial sundial boondoggle.

- eru 6mo agoA space elevator is not aligned with the axis of earth's rotation. It sounds like what you are describing is a different device?
- marginalia_nu 6mo agoWhy would a sun dial need to point in the north/south direction? It just needs to point up along the normal axis of the ground (assuming flat ground).
- eru 6mo agoFrom the original comment I replied to: > Jam a stick in the ground aligned with the earth's axis and take your bearing from the shadow's direction.
- marginalia_nu 6mo agoAh, that comment would be incorrect.
