IMAX Hubble 3D & the James Webb Space Telescope
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
IMAX Hubble 3D, hitting the theaters on March 19, features the most famous space telescope of all, the Hubble, launched in April 1990. Soaring above the earth's atmosphere, it gives the clearest picture of the universe without atmospheric disturbances.
Astronauts were sent to service the telescope on five separate missions, the last in 2009 and the most ambitious. Without these delicate but dangerous space repairs, the Hubble would have been a piece of useless space junk.
This movie chronicles one of these space missions.
Judging by scientific citations in science journals, the Hubble is perhaps the most cited scientific instrument of all time.
Besides giving us spectacular photographs from space, it has given us:
Rescuing the Hubble in 2009 was very risky, since astronauts could not safely flee to the International Space Station (ISS) in case of trouble, but it was successful.
The repairs should last until 2014, when the telescope will be decommissioned. It will be replaced by the James Webb Space Telescope (JWST).
According to NASA - The new telescope has a 6.6-meter diameter primary mirror and has a 25-square-meter collecting area formed from eighteen hexagonal segments. Comparable to the Hubble Telescope, the JWST collecting area is about 6 times larger giving it much more light-gathering power. It will primarily operate in the infrared but will have some capability in the visible range as well. The JWST will also operate much further away than the Hubble Telescope. To give you an idea, Hubble currently orbits the Earth at about 570 kilometers. The JWST will be operating at approximately 1.5 million kilometers from Earth at the second Lagrange (L2) point and will be launched on an Ariane 5 rocket.
It will be interesting to see the stunning imagery from the Webb Telescope once it's in operation but we will of course have to wait until mid-decade or so.

The famed author headed to the pond thanks to Indian philosophy.
- The famed author was heavily influenced by Indian literature, informing his decision to self-exile on Walden Pond.
- He was introduced to these texts by his good friend's father, William Emerson.
- Yoga philosophy was in America a century before any physical practices were introduced.
Pfizer's partnerships strengthen their ability to deliver vaccines in developing countries.
- Community healthcare workers face many challenges in their work, including often traveling far distances to see their clients
- Pfizer is helping to drive the UN's sustainable development goals through partnerships.
- Pfizer partnered with AMP and the World Health Organization to develop a training program for healthcare workers.
A little goes a long way.
- A recent study from the Department of Health and Human Services found that 80 percent of Americans don't exercise enough.
- Small breaks from work add up, causing experts to recommend short doses of movement rather than waiting to do longer workouts.
- Rethinking what exercise is can help you frame how you move throughout your day.
