Hephaestus, the technician God!
One of the 12 Olympian Gods was a mechanic engineer!
But let's take things from the beginning.
Hephaestus was son of Zeus and Hera. When he was born he was so small and weak that his mother took such a shock that she never wanted to see him again. She threw him away from Olympus (the mountain the Gods lived on), but Hephaestus was lucky! He fell into the sea where Thetis and Eurynome found him. They took him to an underwater cave and took good care of him until he became an persons . There, in the underwater cave, Hephaestus created his first laboratory and was making many gold things and jewellery for the women that had saved him.
As a revenge on his mother Hera, he made a golden throne and sent it to her. When Hera sat on it, automatically chains tied her on it! Hephaestus didn't even for a moment considers to release her. Then Dionysus went to him and after getting him drunk convinced him to release his mother, the Goddess of the sky.
Nine years later, Hercules noticed a beautiful jewel that Thetis had and forced her to tell him where she had found it. She told the truth and this impressed the Gods so much that Hephaestus was brought to Olympus and became acceptable by the other Gods. There he got a beautiful laboratory with twenty furnaces burning day and night and had the Goddess of beauty Venus to be his wife!
After a fight with his father Zeus he was thrown again from Olympus to the island of Lemnos. This time he was not so lucky and he got both his legs broken. Since then he was using golden crouches to walk.
One day that he got bored to stop working all alone, he made some golden robots with woman's shape that could help him to walk, to work, and talk with him. He had also made a lot of tables with....Read more @ https://techablyengineering..com/2018/06/hephaestus-technician-god_53.html

Electric Material in Mantle Could Explain Earth's Rotation

Electric Material in Mantle Could Explain Earth's Rotation

When it comes to Earth's rotation, you might think geophysicists have pretty much everything figured out. Not quite. In order to explain some variations in the way our planet spins, Earth's mantle—the layer of hot, softened rock that lies between the crust and core—must conduct electricity, an ability that the mantle as we know it shouldn't have. Now, a new study finds that iron monoxide, which makes up 9% of the mantle, actually does conduct electricity just like a metal, but only at temperatures and pressures found far beneath the surface.
Earth's spin isn't flawless. Geophysicists have discovered that the time it takes our planet to complete one rotation—the length of a day—fluctuates slightly over the course of months or years. They've also noticed extra swing in the predictable wobble of Earth's axis of rotation, like the swaying of a spinning top. The variations are probably caused by the solid iron inner core, liquid metal outer core, and rocky mantle rotating at slightly different rates. Friction helps bring them into line, and the magnetic field of the outer core can pull on the metal inner core. But to really fit the observations, the core should also exert its magnetic tug on the mantle, says Bruce Buffett, an earth scientist at the University of California,......read more @ https://techablyengineering..com/2018/06/electric-material-in-mantle-could.html
