California is the most populous state of the United States. Located on the Pacific coast of North America, it is bordered by Oregon to the north, Nevada and Arizona to the east and southeast in the United States, and Mexico's Baja California to the south. The state's four largest cities are Los Angeles, San Diego, San Jose and San Francisco. California is known for its Mediterranean climate and ethnically diverse population. The state has fifty-eight counties.

Inhabited by indigenous people for millennia, Alta California was first colonized by the Spanish Empire in 1769, and after Mexican independence in 1821, continued as part of Mexico. Following one brief week as the independent California Republic in 1846, and the conclusion of the Mexican-American war in 1848, California was annexed by the United States and was admitted to the Union as the thirty-first state on September 9, 1850.

California's diverse geography ranges from the sandy beaches of the Pacific coast to the rugged, snow-capped Sierra Nevada mountains in the northeast. The central portion of the state is dominated by the Central Valley, one of the most vital agricultural areas in the country. The Sierra Nevada contains Yosemite Valley, famous for its glacially-carved domes, and Sequoia National Park, home to the largest living organisms on Earth, the giant sequoia trees, and the highest point in the contiguous United States, Mount Whitney. The tallest living things on Earth, the ancient redwood trees, paste the northern coastline, mainly north of San Francisco. California is also home to the lowest and hottest place in the Western Hemisphere, Death Valley. Bristlecone pines located in the White Mountains are the oldest known trees in the world; one has an age of 4,700 years.

An air photo of Inyo Craters
The Mono–Inyo Craters are a north–south-trending volcanic chain in Eastern California that stretch 25 miles (40 km) from the northwest shore of Mono Lake to south of Mammoth Mountain. The chain is located in Mono County in the U.S. State of California. Eruptions along the narrow fissure system under the chain began in the west moat of Long Valley Caldera 400,000 to 60,000 years ago. Mammoth Mountain was formed during this period. Multiple eruptions from 40,000 to 600 years ago created Mono Craters and eruptions 5,000 to 500 years ago formed Inyo Craters. The area has been used by humans for centuries. Obsidian was collected by Mono Paiutes for making sharp tools and arrow points. Mono Mills processed timber felled on or near the volcanoes for the nearby boomtown Bodie in the late 19th to early 20th centuries. Water diversions into the Los Angeles Aqueduct system from their natural outlets in Mono Lake started in 1941 after a water tunnel was cut under Mono Craters. Mono Lake Volcanic Field and a large part of Mono Craters gained some protection under Mono Basin National Forest Scenic Area in 1984. Resource use along all of the chain is managed by the United States Forest Service as part of Inyo National Forest.

Selected biography

Linus Pauling in 1954
Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American scientist, peace activist, author and educator. He is considered one of the most influential chemists of the 20th century and ranks among the most important scientists in history. Pauling was one of the first scientists to work in the fields of quantum chemistry, molecular biology and orthomolecular medicine. He is also a member of a small group of individuals who have been awarded more than one Nobel Prize, one of only two people to receive them in different fields (the other was Marie Curie) and the only person in that group to have been awarded each of his prizes without having to share it with another recipient.

Pauling was born and raised in Oregon. He attended Oregon Agricultural College and graduated in 1922 with a degree in chemical engineering. Pauling then went to the California Institute of Technology (Caltech), where he received his Ph. D in physical chemistry and mathematical physics in 1925. Two years later, he accepted a position at Caltech as an assistant professor in theoretical chemistry. In 1932, Pauling published a landmark paper, detailing his theory of orbital hybridization and analyzed the tetravalency of carbon. That year, he also established the concept of electronegativity and developed a scale that would help predict the nature of chemical bonding.
