Apollo 13 is an exciting movie ― and a true story! It is Monday, April 13, 1970 and Apollo 13 is flying to the Moon. Suddenly, something goes wrong. The ship is losing power and oxygen. Will the astronauts walk on the Moon? Will they get home again?
Discovery School - 100 Greatest Discoveries - Chemistry
1. Oxygen (1770s) Joseph Priestley discovers oxygen; later, Antoine Lavoisier clarifies the nature of elements. Priestley produces oxygen in experiments and describes its role in combustion and respiration. Then, by dissolving fixed air in water, he invents carbonated water. Priestley, oblivious to the importance of his discovery, calls the new gas "dephlogisticated air." Lavoisier gives oxygen its name and correctly describes its role in combustion.
Ax and the Animorphs are about to have a huge problem. It starts when they decide to morph mosquitoes in order to slip by some unsuspecting Yeerks. It ends with them stuck in Zero-space with no idea how they got there, no way to get back to Earth...and no oxygen. Luckily, an Andalite scout ship finds them before it's too late. But now Ax is finally with his own people. And he doesn't know if he ever wants to go back to Earth...
Peroxides are supposed to be bad for you. Free radicals and all that. But now we hear that hydrogen peroxide is good for us. Hydrogen peroxide will put extra oxygen in your blood. There's no doubt about that. Hydrogen peroxide costs pennies. So if you can get oxygen into the blood cheaply and safely, maybe cancer (which doesn't like oxygen), emphysema, AIDS, and many other terrible diseases can be treated effectively. Intravenous hydrogen peroxide rapidly relieves allergic reactions, influenza symptoms, and acute viral infections.
