Egyptian blue is the oldest known artificial pigment. The color blue throughout human history has been one of the most cited, identifying it with royalty and divinity, due to its difficulty in obtaining it.

Blue pigments have been used since ancient times, but later than other pigments such as red, dark brown or ocre, which are more easily obtained naturally and are now used in art. But the most cited blue pigment comes from minerals such as pencil, which are rare and therefore very expensive.

The largest lapislazuli deposits are in Afghanistan's Hindukush, where they are still operated with very similar procedures to those employed more than 3000 years ago.

The Earth is almost never shown like this, and in the meantime, this is our planet from the side of the Pacific Ocean 🌊.
One side of the Earth is almost completely covered with water (the Pacific), while landmass is almost all on the other side.

Wealth is not the room being full of magnificent and ostentatious objects.
Wealth is the ability to provide prosperity and security to its people.
That is why Japan is one of the richest countries in the world.

Why is half of the ship black and half of it is silver colored?
that's because the bottom as seen from orbital entry is, has a heat shield on it. So the black there is the heat shield and then the core structure of the rocket is a special alloy of stainless steel and that's

There is a double standard in how the media covers interracial violence.
When the victim is black, it’s national news.
When the victim is white, it’s often ignored.
This is called selection bias.
And it’s creating division.
The goal is equality.
Not to flip inequality.
