Why are top predators so rare?
Why are top predators so rare? This energy constraint is the fundamental reason top predators are so rare. Many food webs consist of half a dozen or more trophic levels, and by the time you get to the top, there’s simply not that much energy left. It’s their naturally small populations that also leave these […]

What is the ideal gas thermometer?
What is the ideal gas thermometer? In principle, we can measure the same temperature using any gas, so long as the constant operating pressure is low enough. When we do so, our device is called the ideal gas thermometer. The (very nearly) direct proportionality of two low-pressure real gas volumes contrasts with what we observe […]

Are linear and angular momentum conserved separately?
Are linear and angular momentum conserved separately? Now, such an object can be assumed to have a constant mechanical energy. But that is only one part of the story. The fact is, since each linear and angular momentum of this object is conserved, the respective components of its linear and angular energy also would be […]
Why can sound not travel through space?
Why can sound not travel through space? Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would […]
