The Universe in a Nutshell: The Physics of Everything
Michio Kaku, Henry Semat Professor of Theoretical Physics at CUNY
What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein’s “e=mc^2.” Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.
New telescopes come with a couple different types of inexpensive finders – magnifying and non-magnifying ones. In this video, David Fuller of “Eyes on the Sky” takes the viewer through the various types of basic finders, highlighting the benefits and drawbacks of each so the viewer can make a better educated decision when purchasing a new telescope. Also covered is how to align a finderscope with the main telescope, with a visual demonstration of how it might look for the viewer.
Barlow lenses are an inexpensive – and often effective – way to increase the magnification and eyepiece collection of amateur astronomers. In this video, David Fuller of “Eyes on the Sky” takes the viewer through the various types, caveats and benefits with using them, as well as what to look for when shopping for one.
This video about the basics of telescopes discusses field of view, in particular, the difference between apparent field of view (AFOV) and telescopic field of view (TFOV). With an explanation of the math used to calculate these plus various examples of the calculations and visuals, the viewer can finish this video with a more complete understanding of this concept that is often confusing to beginning amateur astronomers who are new to telescopes.
Hosted by David Fuller of “Eyes on the Sky,” this video goes over the various sizes and types of basic eyepieces for many amateur telescopes. The three most common eyepiece barrel diameters are discussed, as well as the types of lens configurations which determine how well the eyepiece forms an image for the user – including the concept of eye relief which can matter a lot to those who wear eyeglasses. Discussed are Huygens, Ramsden, Kellner, RKE, Modified Achromat, Plossl and some advanced designs, plus some information about anti-reflection coatings. An excellent primer for anyone wanting to understand more about telescope eyepieces.
Hosted by David Fuller of “Eyes on the Sky,” this video discusses the basics of telescope magnification and focal ratio. Each concept is covered, guiding the viewer through how to calculate magnification of a telescope and eyepiece combination, and how to determine the focal ratio of a given telescope. An excellent primer for anyone wanting to understand more about telescopes.
“The Mars Underground”- A documentary on when we may get to Mars and why it is taking so long.
In this video Robert gives you our top five tips to coax the best possible views of planets regardless of the cost or quality of your telescope.
It doesn’t matter if your telescope costs tens, or thousands : it always makes sense to try to get the best views you possibly can when observing planets. And sometimes improving the view involves no more than selecting the best site available to you to set up the telescope or using the telescope within its ideal power range — this video will give you the information you need to consistently get the best views of planets with your telescope.

I know all of you are busy preparing for your terminal exams, so I am posting only videos of shorter duration. On Oct 19th 2010, astronomers announced the measurement of a redshift of 8.6 for one of the galaxies in the Ultra Deep Field. Here’s the news release from ESO’s website. This is old news but relevant to understanding the Cosmos.
The question of what caused the Big Bang is one of the most difficult facing humanity. We may never find an answer, and even if we do, we probably won’t understand it. It’s difficult to imagine an event occurring without a cause, and yet, that is precisely the prospect we are faced with when it comes to this question.

Mars Orbiter Mission was launched on the 5th of November at 14:38 pm from SDHC, SHAR, Sriharikota. This is India’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit. The Mission is primarily a technological mission considering the critical mission operations and stringent requirements on propulsion and other bus systems of spacecraft. One of the main objectives of the first Indian mission to Mars is to develop the technologies required for design, planning, management and operations of an interplanetary mission.
Following are the major objectives of the mission:
A. Technological Objectives:
Design and realisation of a Mars orbiter with a capability to survive and perform Earth bound manoeuvres, cruise phase of 300 days, Mars orbit insertion / capture, and on-orbit phase around Mars.
Deep space communication, navigation, mission planning and management.
Incorporate autonomous features to handle contingency situations.
B. Scientific Objectives:
Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.
In response to one of my posts earlier on the Rosetta Mission, some of you had asked me why should we study a comet. In this Video from JPL, scientists tell you why.
