How can this be if energy is conserved? If we are not running out of energy, what are we really running out of? An inefficient machine is said to 'waste energy'. Does that mean energy is actually lost? Explain. Some of the energy we produce is wasted, for example, heat from a ...
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms. These metabolisms raise the possibility of Ven...
Imagine living in a place where your survival depends upon living within your limits, not consuming more food and energy than you produce, creating enough fresh water and air to live on, reducing waste to a bare minimum, recycling everything that you can, and avoiding contaminating the environm...
(b) How is this pigment made? (c) Where is it made? (d) Where is it primarily located? Why does the lack of melanin produce a blue/bluish-colored iris? What forms this color? Briefly describe two things that can be learned from examining emissions or absorption spectra...
The model can also show how dark energy is not an increase in energy that is causing the accelerated expansion of the universe, but is an accelerating decrease in matter throughout the universe as the stars and galaxies in the universe continue to convert matter into energy during their life ...
Zero stars: Dried out my house when I was already dehydrated - BButton1869 PotatoGod (talk) 20:42, 30 January 2025 (UTC) I'm not sure conservation of mass is the right law here. It would be possible to increase humidity without using water or violating the conservation of mass, ...
We propose a mechanism to explain the low-frequency QPOs observed in X-ray binary systems and AGNs. To achieve this, we perturbed stable accretion disks ar
Carbon nanostructures seen in circumstellar envelopes surrounding carbon-rich stars could have a chemical origin with soot particles created during fuel combustion. Image Credit: Shutterstock.com/ lucadp According to KAUST researchers, each process could be based on the same reaction mechanism. The su...
It takes some effort to see the depth in what at first seems to be a random dot pattern. Not everyone can do that on the first try. There are lots of resources online which teach how to do that. The good thing is it's like riding a bicycle: once you got it right for the first...
Notice how fireworks always make symmetrical explosions? If one part of the firework goes left, another part goes to the right. You never see a firework sending all its stars to the left or a bigger series of explosions to the left than to the right: the explosion is always perfectly ...
