Steve Wozniak discusses the passing of Steve Jobs and discusses all the good times he and Jobs had together at Apple. Steve Paul, along with Steve Wozniak and Ronald Wayne, was the chairman, and CEO of Apple Inc. He is known for his Apple products and revolutionizing the computer and smartphone industry. Jobs died at his Palo Alto, California, home around 3 pm on October 5, 2011, from respiratory arrest.

Professor Martinez J. Hewlett of the University of Arizona describes the moral and theological controversy that the Human Genome Project caused when the sequencing of DNA first began in the 1990s. The first draft of the Human Genome Project was published in "Nature" on February 15, 2001 with the final sequencing mapping completed on April 14, 2003.

Steve Jobs, CEO of Apple Inc. introduced the original iPhone that has capabilities to reinvent the phone. His first person account reveals that the new item will have three things: touch controls, revolutionary mobile phone and breakthrough internet communication device. The iPhone is a line of smartphones designed and marketed by Apple Inc. The first generation iPhone was released on June 29, 2007. The user interface is built around the device's multi-touch screen, which includes a virtual keyboard.

Paleoanthropologist Dr. Donald Johanson recalls the day he found Lucy's skeleton with grad student Tom Gray at the Hadar Formation in the Afar Triangle of Ethiopia. Lucy was discovered on November 30, 1974.

Paleoanthropologist Dr. Donald Johanson recalls how Lucy the Australopithecus afarensis received the nickname of Lucy. The now famous skeleton was found on November 30, 1974 by Johanson in Ethiopia.

Paleoanthropologist Donald Johanson explains the scientific importance of finding Lucy's skeleton and hypothesizes what she would be like in person. Lucy the Australopithecus afarensis was discovered on November 30, 1974 by Johanson in Ethiopia.

SPECTRUM: You, Frederick Durant, and Ernst Stuhlinger were all in Barcelona at an International Astronautical Federation meeting on 4 October 1957. What was your reaction when you got the news about Sputnik?

CLARKE: Although I had been writing and speaking about space travel for years, I still have vivid memories of exactly when I heard the news. I was in Barcelona for the 8th International Astronautical Congress. We had already retired to our hotel rooms after a busy day of presentations by the time the news broke. I was awakened by reporters seeking an authoritative comment on the Soviet achievement. Our theories and speculations had suddenly become reality!

For the next few days, the Barcelona Congress became the scene of much animated discussion about what the United States could do to regain some of its scientific prestige. While manned spaceflight and Moon landings were widely speculated about, many still harboured doubts about an American lead in space. One delegate, noticing that there were 23 American and five Soviet papers at the Congress, remarked that while the Americans talked a lot about spaceflight, the Russians just went ahead and did it!

SPECTRUM: In the past 50 years, has the Space Age lived up to your expectations?

CLARKE: On the whole, I think we have had remarkable accomplishments during the first 50 years of the Space Age. Some of us might have preferred things to happen in a different style or time frame, but when our dreams and aspirations are adjusted for reality, there is much we can look back on with satisfaction. (For example, in 1959 I took a bet that men would be landing on the Moon by June 1969, and lost only very narrowly.) And in the heady days of Apollo, we seemed to be on the verge of exploring the planets through manned missions. I could be forgiven for failing to anticipate all the distractions of the 1970s that wrecked our optimistic projections—though I did caution that the Solar System could be lost in the paddy fields of Vietnam. (It almost was.)

SPECTRUM: A lot of what was achieved at the beginning of the Space Age—from Sputnik to the first landing on the moon—was spurred on by the rivalry that was the Cold War. Without that competition, do you think the human impetus to reach for space has slowed somewhat?

CLARKE: Launching Sputnik and landing humans on the Moon were all political decisions, not scientific ones, although scientists and engineers played a lead role in implementing those decisions. (I have only recently learned, from his long-time secretary Carol Rosin, that Wernher von Braun used my 1952 book, The Exploration of Space, to convince President Kennedy that it was possible to go to the Moon.) As William Sims Bainbridge pointed out in his 1976 book, The Spaceflight Revolution: A Sociological Study, space travel is a technological mutation that should not really have arrived until the 21st century. But thanks to the ambition and genius of von Braun and Sergei Korolev, and their influence upon individuals as disparate as Kennedy and Khrushchev, the Moon—like the South Pole—was reached half a century ahead of time.

I hope that nations can at last see better reasons for exploring space, and that future decisions would be informed by intelligence and reason, not the macho-nationalism that fuelled the early Space Race.
