A new mathematical equation describes the distribution of different fragment sizes when an object breaks. Remarkably, the ...

One truly elegant hypothesis of physics is the "zero-energy universe" hypothesis. It proposes that the net sum of the energy in the universe perfectly equates to zero. According to the idea, if you ...

Measuring mass with marble fizz and massive bricks! Matter cannot be created nor destroyed. But weight, there’s more to know about the Conservation of Mass! STEM Challenge: Designing a Simple Balance ...

What happens to mass? What is the difference between weight and mass? Working scientifically The mass of a gas Test your knowledge 10 grams of sugar plus 200 grams of water equals a total of 210 grams ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...

Segment 4H: Conservation of Energy We explore the inner workings of a hydroelectric dam. Segment 4H: Conservation of Energy We explore the inner workings of a hydroelectric dam as we learn about the ...

Students will be able to make measurements showing that whether the process is a change of state, dissolving, or a chemical reaction, the total mass of the substances does not change. Note: In the ...

Law Of Conservation Of Mass: Did you know that in water the ratio of the mass of hydrogen to the mass of oxygen is always 1:8? This led to one of the laws of chemical combination, the law of constant ...

Sir Isaac Newton first stated the laws of motion in Principia Mathematica back in 1687 and today those laws are seen as facts - that when something moves it has to push against something else. But a ...

On a warm summer evening, a visitor to 1920s Göttingen, Germany, might have heard the hubbub of a party from an apartment on Friedländer Way. A glimpse through the window would reveal a gathering of ...
