Fact of the day #4

Why is the sky blue? Very big question.

The dispersion of the solar rays, commonly known as Rayleigh scattering, explains that the light that enters in the atmosphere collides with all the molecules (mostly nitrogen and oxigen) and rebounds like a pinball. If all the solar rays sacttered evenly, we would see the sky white. But blue light scatters easier than the red or yellow ones, thats because the blue light has less wavelength. Thats because we see the sky blue.

Bonus: the clouds are white for the same reason, alike the air, water molecules disperse all type of wavelength equally, so we see all the colors at the same time (we do not distinguish each of the colors individually since they all arrive simultaneously combined from the same poin), which makes white. When the clouds are color grey, its because the clouds have more water density, so they let pass through less light.

Fact of the day #3

Hassium

This radioactive material was discovered in 1984 by Peter Armbruster and Gottfried Münzenberg and only a few atoms have ever been made. The name is derived from the German state Hesse, where it was made for the first time.

It belongs to the transition metals group and it's atomic number is 108 and in ambient temperature is in solid state. It's boiling point, melting point and density it's unknown.

Hassium does not occur naturally and it will never be isolated in observable quantities. It is created by bombarding lead with iron atoms. Nowadays its only used in research.

Fact of the day #2

Etymology if the word museum:

Museum was also used as library or academy, therefore nowadays it's the library of art.

From Greek moyseîon and the in Latin museum, it refers to 'Temple of the Muses in the Parthenon'. The muses were sons of Memory and goddesses of inspiration. The museum of Alejandria tried to reunite the most important thinkers of the time.

Fact of the day #1

Did you know that Saturn is the only planet that would float in the water?

This happens because its density, the property of materials that determines whether or not it floats on water. But how does this works? Well its kind of easy actually. Arquimedes realized that when we get into a bathtub full of water, the water rises (obvious right?). Lets imagine the bathtub is full to the brim, when you get into the bathtub the water overflows. Well if we collect all this water its equal to the buoyancy force. If this force is lower than our weight, we drown, if not, we float. Thus, wood, which for the same volume weighs less than water, floats, while steel, which is denser than water (which for the same volume, steel weighs more), drowns.

Saturn is mostly made of gas, so its density its really low, what makes it flote.
