Theodore Roosevelt (also known as “Teddy” or “T.R.”) is known for having been in the cavalry, leading the Rough Riders’ charge on San Juan Hill, commissioning the Panama Canal, creating the US National Park System, and saying “speak softly, but carry a big stick” (the aircraft carrier USS Theodore Roosevelt is called “the big stick” by its crew). Before he became the 26th President of the United States, he was a governor, historian, adventurer, police chief, cavalryman, cowboy, explorer, hunter, naturalist, Assistant Secretary of the Navy, author of 35 books, conservationist, etc. He was a larger-than-life figure with a bombastic reputation as a total Badass.
- Magnesium (Wikipedia)
Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium.
