Touch both objects. They’re the same temperature, but the wood feels warmer, right? Why is that? It’s not about temperature but thermal energy. When your hand touches an object, there is a heat conduction interaction. Energy is transferred from your warmer hand to the cooler object until the two are …

What exactly is AI Scientist—just a fancy kind of neural net? It’s not a single neural network, but rather an ensemble of computer programs that can help scientists make new discoveries. My group has already developed algorithms that can help with individual tasks, such as weather forecasting, identifying the drivers …

Since the change in kinetic energy is still zero, this means that the positive change in gravitational potential energy is equal to the negative of the change in internal energy. Let’s say you have a mass of 75 kilograms (165 pounds). That means moving up 1 meter would reduce your …

When you swap two paraparticles, these hidden properties change in tandem. As an analogy, imagine that these properties are colors. Start with two paraparticles, one that’s internally red and another that’s internally blue. When they swap places, rather than keeping these colors, they both change in corresponding ways, as prescribed …
