One of the most amazing facts in physics is this: Quantum physics everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. All of the other weird stuff you might have heard about quantum physics, Schrodinger’s Cat, God playing dice, spooky action at …

How much can we really know about the universe beyond our galaxy? The Hubble Telescope has enabled us to see objects in space as far 13,000,000,000 light years away. But this still doesn’t give us the answers to all our questions, questions like, “What is the universe made of?” “Which elements are the most abundant?” …

Cloudy climate change: How clouds affect Earth’s temperature. Earth’s average surface temperature has warmed by .8 Celsius since 1750. When carbon dioxide concentrations in the atmosphere have doubled, which is expected before the end of the 21st century, researchers project global temperatures will have risen by 1.5 to 4.5 degrees Celsius. If the increase is …

When the infamous fictional character, Carrie White, left her high school prom hall ablaze, and brought terror upon her town, she relied on her powers of telekinesis, the ability to manipulate physical objects using the power of the mind alone. But while Carrie is just a fictional film based upon a fictional book, belief in …

Vitamins are organic compounds we need to ingest in small amounts to keep functioning. They’re the body’s builders, defenders and maintenance workers, …
The city sky is, frankly, rather boring. If you look up at the patches of murk between buildings, you might be able to pick out The Big Dipper, or perhaps, Orion’s Belt. But hold on. Look at that murky patch again and hold our your thumb. How many stars do you think are behind it? …
