Cover Page TMT`Thirty Meter TelescopeSpecail Report (in English) TMT`Thirty Meter Telescope Tomonori Usuda (TMT-J Project Director) and Miki Ishii (Public Relations) TMT-J Project Office, National Institute of Natural Sciences/ National Astronomical Observatory of Japan TMTiThirty Meter Telescopejis an extremely large optical/infrared telescope with an aperture of 30m, whose construction began in the fall of 2014 atop Mauna Kea on the island of Hawaii and is scheduled for completion in 2022. In comparison to the 8.2m Subaru Telescope, one of few telescopes currently at the forefront of astronomical observation, TMT will have 13 times the light-gathering power and 3.6 times the resolving power, enabling it to perform at an unprecedented level of sensitivity. Utilizing this power to its fullest extent, TMT will aim to search for evidence of life on extrasolar planets and to reveal the identity of astronomical objects in the very early universe. Space Japan Book Review (in English) From a satcom researcher point of view Nate Silver: gThe Signal and The Noise ?Why So Many Predictions Fail-but Some Don'th, Penguin Press, 2012. Dr. Takashi Iida Editorial Advisor "Signal", which is in the title of this book, means truth, and "noise" means those that deflect the eye from the truth. The "signal" and the "noise" are originally terms of electrical engineering, as mentioned in this book. In the case of our handling telecommunications, especially in the radar, the signal processing is combating signal and noise. In order to determine whether the received signal is a significant reflected signal or the noise, Bayes theorem is applied as described in this book. Since such a treatment for even signal in a satellite communication is familiar, this book is thought to be appropriate to this column. This book review is based on Japanese translation version.
