Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

How do skateboarders seemingly defy gravity? How do gymnasts flip in the air? They have skill — and, as a Times interactive explored, an understanding of the laws of motion, physics and energy. By ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...

Are these machines possible without violating the laws of physics? No. A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free ...

Rotational motion can feel tricky, but with the right approach, it becomes a powerful tool in your physics toolkit. From angular velocity to torque, understanding these concepts is key to solving real ...

Chinese robotics firm LimX Dynamics has launched a full-size humanoid robot designed to accelerate ...
