The Drake Equation by Bart KingNoah Grow is a bird-watcher. If youre picturing some kid in a big floppy hat, peering up into trees through giant binoculars . . . well, good job. Thats exactly what he does. Right now, Noah is on a quest to find a wood duck. According to his calculations, aka the Drake Equation, the odds are good-really good-for spotting one.
Thats why he gets off the bus at the wrong stop. And thats how he ends up running down a hill, crashing into a fence, and landing right next to a strange, glittery disk.
Noah and his best friends, Jason and Jenny, soon discover that the mysterious disk is, well, mysterious. It gives Noah peculiar powers. As things go from odd to outrageous, Noah is swept up in a storm of intergalactic intrigue and middle-school mayhem. Theres much more at stake than Noah realizes.
Bart King delivers a hilarious sci-fi adventure with just the right mix of heart and humor that will have readers looking out for birds-and strange alien objects.

Drake Equation: Estimating the Odds of Finding E.T.
Explore our diverse programs and resources and see how they can help you better understand and share the wonder of astronomy as the gateway to science literacy. The ASP is partnered on a NASA project to create new astronomy badges for Girl Scouts, connect them with their local astronomy clubs, and train amateur astronomers to make their outreach more girl-friendly. Through an NSF grant, we have created a set of research-based, science-rich astronomy activities that are engaging and developmentally appropriate for pre-K aged children, and trained hundreds of educators at museums, parks, and libraries across the U. AFGU provides informal science educators and interpreters with new and innovative ways to communicate astronomy. AFGU is a growing community of hundreds of educators from museums, science centers, nature centers, and parks around the U.

Are humans unique and alone in the vast universe? This question--summed up in the famous Drake equation--has for a half-century been one of the most intractable and uncertain in science. But a new paper shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.
I have decided to turn the preparation that I did for that panel, and notes taken during the panel discussion, into a tutorial on the Drake Equation. Dubbed Project Ozma, for a period of 6 hours a day for four months the NRAO radio telescope listens for radio signals of intelligent origin. None are found. Within a year a meeting is hosted in Green Bank to explore the issue of extraterrestrial intelligence. Frank Drake needed to come up with an agenda for the meeting in order to provide some structure to the discussion. To serve as an agenda, he devises the Drake Equation. Sometimes known as the Sagan-Drake Equation in the past, the meeting was attended by approximately a dozen interested parties.
Suitable for life?
The Drake Equation is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe. First proposed by radio astronomer Frank Drake in , the equation calculates the number of communicating civilizations by multiplying several variables. The challenge at least for now is that astronomers don't have firm numbers on any of those variables, so any calculation of the Drake Equation remains a rough estimate for now. There have been, however, discoveries in some of these fields that give astronomers a better chance of finding the answer. These stars, however, are red dwarfs that might be too volatile for life. More study is needed to understand where life might be possible, and whether it could persist long enough to communicate with other civilizations.
