Michio Kaku answered to questions from followers and fans on Google Hangout about his new book The Future of the Mind. The book became #1 New York Times Bestseller and is Kaku’s first book on human mind and consciousness. In the Q&A Kaku talked about what he thought about the origin of consciousness, mind and human soul, he also talked about immortality and the future of humanity.
Sunday March 9th will be the premier of the remake of Cosmos with American physicist Neil Degrasse Tyson. The original series conducted by Carl Sagan in 1980 was a series of 13, 1 hour episodes that narrated a visual journey through space and the universe. Although the 1980’s Cosmos series lacked the realistic special effects we have nowadays it had one of the greatest genius of all time, Carl Sagan. Sagan’s unique tone of voice, his communication ability and passion towards knowledge and discovery made Cosmos a really inspirational TV show, that changed the lives of many. Neil Degrasse Tyson has a huge challenge today to carry on with Sagan’s legacy and timeless show, we hope he will not disappoint the audiences. Tyson carries on with the Cosmos legacy with more than 30 years of advancements in special effects and computer graphics animation and new discoveries in quantum physics, space exploration and discoveries in astronomy.
The word SOFIA stands for (Stratospheric Observatory for Infrared Astronomy) it is Nasa’s first airborne telescope nested in a Boeing 747.
(Watch the SOFIA explanation video below)
Because the Earth’s atmosphere absorbs light wavelengths it is difficult for astronomers closer to the sea level to detect lower spectrums of infrared and ultraviolet radiation. This created the necessity to reach for higher altitudes above earths lower atmosphere the troposphere to see the stars with less distortion in between caused by turbulence, water vapor and the ozone layer.
SOFIA is based on a Boeing 747SP wide-body aircraft that has been modified to include a large door in the aft fuselage that can be opened in flight to allow a 2.5 meter diameter reflecting telescope access to the sky. This telescope is designed for infrared astronomy observations in the stratosphere at altitudes of about 41,000 feet (about 12 km). SOFIA’s flight capability allows it to rise above almost all of the water vapor in the Earth’s atmosphere, which blocks some infrared wavelengths from reaching the ground. At the aircraft’s cruising altitude, 85% of the full infrared range will be available.
Stars don’t twinkle in the stratosphere
SOFIA does its astronomic observation at the stratosphere which is one of Earth’s largest atmospheric layers. It is a 40km layer situated above 10 to 13 km (30,000–40,000 ft; 6–8 mi) above sea level. At the stratosphere stars don’t twinkle due to the lack of air turbulence at these high altitudes these conditions are ideal for observing star formation which emits low levels of radiation which can be detected from the stratosphere.
Michiko Kaku is like the Asian version of Einstein, he has become famous after writing several best selling books on theoretical physics. He has demonstrated his genius from early age by creating a homemade particle accelerator in his backyard for his third grade science fair. His major achievement are his discoveries in string theory where he describes the universe as music, and the string’s elemental particles as musical notes.
On this 40 minute video Kaku simplifies the universe in its most comprehensive and simple manner from the Big Bang to string theory and the future of mankind.
