Ocean Exploration Technologies: Past, Present, and Future
Lecture by Robert D. Ballard, Founder and Director of the Center for Ocean Exploration, Graduate School of Oceanography/University of Rhode Island; Founder and President of the Ocean Exploration Trust and Senior Scientist Emeritus, Woods Hole Oceanographic Institution
What does the future of ocean exploration look like? Deep-sea explorer Robert D. Ballard, famous for the discovery of hydrothermal vents, “black smokers,” and the wreck of the RMS Titanic, will discuss the history and future of ocean exploration technologies. From the earliest manned deep-diving submarines to the latest remotely operated vehicle (ROV) systems that use satellite technology to transmit data in real time, technology has increasingly made interactive ocean exploration a reality. Ballard will highlight past scientific achievements in ocean exploration and outline the opportunities ahead for using advanced tele-presence technologies.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
San Francisco (SF; ; Spanish for 'Saint Francis'; Spanish: [ˈsãɱ fɾãnˈsisko]), officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. San Francisco is the 13th most populous city in the United States, and the 4th most populous in California, with 884,363 residents as of 2017. It covers an area of about 46.89 square miles (121.4 km2), mostly at the north end of the San Francisco Peninsula in the San Francisco Bay Area, making it the second most densely populated large US city, and the fifth most densely populated U.S. county, behind only four of the five New York City boroughs. San Francisco is also part of the fifth most populous primary statistical area in the United States, the San Jose–San Francisco–Oakland, CA Combined Statistical Area (8.8 million residents).
As of 2017, it was the 7th highest-income county in the United States, with a per capita personal income of $119,868. The San Francisco CSA was the country's 3rd largest urban economy as of 2017, with a GDP of $878 billion. Of the 574 primary statistical areas in the US, the San Francisco CSA had the highest GDP per capita in 2017, at $99,347 per capita. San Francisco was ranked 14th in the world and third in the United States on the Global Financial Centres Index as of September 2018.San Francisco was founded on June 29, 1776, when colonists from Spain established Presidio of San Francisco at the Golden Gate and Mission San Francisco de Asís a few miles away, all named for St. Francis of Assisi. The California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856. San Francisco's status as the West Coast's largest city peaked between 1870 and 1900, when around 25% of California's population resided in the city. After three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a major port of embarkation for service members shipping out to the Pacific Theater. It then became the birthplace of the United Nations in 1945. After the war, the confluence of returning servicemen, significant immigration, liberalizing attitudes, along with the rise of the hippie counterculture, the Sexual Revolution, the Peace Movement growing from opposition to United States involvement in the Vietnam War, and other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States. Politically, the city votes strongly along liberal Democratic Party lines.
A popular tourist destination, San Francisco is known for its cool summers, fog, steep rolling hills, eclectic mix of architecture, and landmarks, including the Golden Gate Bridge, cable cars, the former Alcatraz Federal Penitentiary, Fisherman's Wharf, and its Chinatown district. San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co., Gap Inc., Fitbit, Salesforce.com, Dropbox, Reddit, Square, Inc., Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, Craigslist, and Weather Underground. It is home to a number of educational and cultural institutions, such as the University of San Francisco (USF), University of California, San Francisco (UCSF), San Francisco State University (SFSU), the De Young Museum, the San Francisco Museum of Modern Art, and the California Academy of Sciences.
As of 2018, San Francisco is the highest rated American city on world liveability rankings.
