Newton is a GPU-accelerated, extensible and differentiable physics simulation engine intended for robotics and research workflows [1]. Our original carousel introduced the engine through its robotics applications.

## A simulator gives you a model of the system

Specify the bodies, joints, contacts and conditions relevant to the behavior you want to study. A useful first simulation is small enough that you can explain what should happen before you run it.

Compare the result with a known case, then vary one condition at a time. That makes it easier to find whether a surprising movement comes from the setup, an assumption or the behavior being studied.

## Keep simulation and reality separate

The engine's documentation establishes its intended capabilities [1]. It does not establish that a particular simulated robot will behave identically in the physical world.

Record the parameters and software version alongside a result. If a decision depends on contact, friction or a sensor assumption, check how sensitive the outcome is to changing it.

Our caption framed the announcement as a question about human dominance. The practical subject is narrower: a tool for studying physical behavior. Evaluate it against the simulation problem you actually have, rather than treating a lively robot demonstration as evidence of general intelligence.
