YouTube: Photography - 1946 Vocational Guidance Film

1940's vocational guidance film that discusses careers in photography and cinematography. 'Photography is often called "the universal hobby." It is a means of creative expression within the reach of people in all walks of life, and it speaks a language that everyone can understand. The camera lens is a mechanical eye: seeing everything, and recording everything. It captures actions that will never again be repeated.'

New Lithium-ion Battery

Quote: Researchers at the University of Illinois at Urbana-Champaign have developed a new lithium-ion battery technology that is 2,000 times more powerful than comparable batteries. According to the researchers, this is not simply an evolutionary step in battery tech, “It’s a new enabling technology… it breaks the normal paradigms of energy sources. It’s allowing us to do different, new things.”

Snippet: 
      "So the bottom line with every review you read online: it describes the behavior of one copy of a lens on one camera. Its a spot of data in a variable landscape. No one review should be the thing that makes you decide for or against a given lens. But several of them should give you a good idea of what you will get, and reading a Public Summary review site should alert you to how much variation there might be" - continued
