Grasping data through physical models

Is it eas­ier to glean insights from data using a phys­i­cal model? Most of the advances in tech­nol­ogy (data visu­al­iza­tion, chart­ing, inter­ac­tive graph­ics) have made it much eas­ier to get insights using on-​screen imag­ing. By and large they have replaced phys­i­cal con­struc­tion and draw­ing of charts with rulers, com­passes, and inks. But what if we […]
