"Does the Past Exist Yet? Evidence Suggests Your Past Isn’t Set in Stone"
Beauty is understanding physics. The veins on a leaf. How something as simple as a derivative can answer so many questions not just on paper but in nature and the world. Beauty is an equal and opposite reaction, ripples on water, force equals mass times acceleration.

This butterfly with transparent wings has a Spanish name, “espejitos,” which means “little mirrors.” If it wasn’t for the opaque outline around the wings, the average observer might not see one perched on a leaf or flower. Check out more amazing transparent animals.
Nature does not hurry yet everything is accomplished.

“The brain, it seems, does not make much of a distinction between reading about an experience and encountering it in real life; in each case, the same neurological regions are stimulated.”
A 10-year study has revealed that the electron is very spherical indeed.
To be precise, the electron differs from being perfectly round by less than 0.000000000000000000000000001 cm. To put that in context; if an electron was the size of the solar system, it would be out from being perfectly round by less than the width of a human hair.
"Our perceptions differ qualitatively from the physical properties of stimuli because the nervous system only extracts certain information from a stimulus and then interprets this information in the context of its earlier experience. We experience electromagnetic waves of different frequencies not as waves but as actual colors that we see: red, blue, or green. We experience objects vibrating at different frequencies as tones that we hear. We experience chemical compounds dissolved in air or water as specific smells or tastes. Colors, tones, smells, and tastes are mental reconstructions created by the brain out of sensory experience. They do not exist, as such, outside of the brain….does a sound exist when a tree falls in the forest, if no one is near enough to hear it? We now believe that the fall causes vibration in the air but not sound. Sound only occurs when pressure waves from the falling tree reach and are perceived by a living being."
If the rotavap (rotary evaporator) is not cleaned as often it should be, than this could happen: algae in the cooling water.
