That relativity theory or quantum mechanics are only important at huge velocities or incredibly small distances and so on is a common misconception. In fact, the yellow color of gold and the stickiness of fridge magnets are relativistic effects. One thing that only works because of quantum mechanics is that a gecko>
In case you haven't heard of it, Nibiru is a totally nuts idea. Yet it gets many people very scared. I started to get messages about it as a result of writing articles about asteroid impacts, and how we can detect and deflect asteroids. It is possible to have beliefs that don't make any sense if you look at them closely>
You can use a simple cat toy (laser pointer) to demonstrate the Tyndall effect. “The Tyndall effect, also known as Tyndall scattering,” according to Wikipedia, “is light scattering by particles in a colloid or particles in a fine suspension.” You can use the laser to test three different mixtures: colloids>
This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere>
A recent placebo-controlled study showed evidence of trans-cranial bright light's effect to brain functions when administered through the ear. Bright light stimulation was found to increase activity in brain areas related to processing of visual sensory information and tactile stimuli. The findings are the first ever>
