Clock Hand Tips
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Accurate clocks set to the same time are on display in a clock shop. The sum of all the pairwise distances between the tips of the second hands ("tip distance sum") minus the sum of all the pairwise distances between the centers of the clock faces ("center distance sum") is graphed. Change the time using the "time" slider. Rearrange the position of the clocks by dragging them or clicking inside the display area. Add new clocks (up to 20) by holding down the Alt key and clicking in the display area.
