Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Fermium is a synthetic, radioactive metallic element. It has the symbol Fm and atomic number 100. It is an element in the actinide series. It is named after nuclear physicist Enrico Fermi. Fermium became the eighth transuranic (having an atomic number greater than 92) element discovered. It was first discovered in 1952 by a team of scientists led by Albert Ghiorso. They found fermium-255 in debris of the first hydrogen bomb explosion from Operation Ivy. Fermium-255 was created when...
