THE ANALOG THING (THAT) THE ANALOG THING (THAT) is a high-quality, low-cost, open-source, and not-for-profit cutting-edge analog computer. THAT allows modeling dynamic systems with great speed, parallelism, and energy efficiency. Its use is intuitively interactive, experimental, and visual. It bridges the gap between hands-on practice and mathematical theory, integrating naturally with design and engineering practices such as speculative trial-and-error exploration and the use of scale models.
