The Equation that Launched 3.4 Million Hosts

My recent Decoded Science article, “The Drake Equation Estimated the Scope of the SETI Project“, explains how one equation set the stage for the Search for Extra-Terrestrial Intelligence. (ET, give us a call).

Can a Math Equation Estimate the Number of Stars with Alien Civilizations?

Scientists don’t want to say, “Look at all those stars! There’s so many, there must be alien life somewhere”. They want to make refined estimates.

The Drake Equation is one of several to estimate the number of aliens we might be able to detect.

My Decoded Science article discusses the factors in the Drake Equation, and what it specifically estimates.

What 3.4 Million Host Computers?

The Drake Equation gave the rationale for the SETI project.

SETI at Home distributes the workload of reviewing the data, as gathered by radio telescopes, to some 3.4 million host computers in people’s homes and in business offices. The stats as of June 27, 2013 show that’s how many host computers have been used by BOINC projects such as SETI at Home.

Because science now knows so much about how levitra cheapest bad things are for the U.S. economically, why would we allow people from a foreign country (such as the counterfeiters from China mentioned above) to not only have the knowledge but also have access to the latest technologies to implement the surgery procedures.

Beyond Drake: a Toronto Connection

My article also discusses the “Seager Equation”, which estimates the number of exoplanets of which we might be able to detect biogasses. (If alien scientists near Alpha Centauri were to use Dr. Sara Seager’s techniques to detect free oxygen in Earth’s atmosphere, they could say “Aha! A 20% oxygen atmosphere is a clear sign that a lifeform is releasing O2 into the air”).

I was pleased to learn that Dr. Seager was born in Toronto, Ontario, Canada; and earned her BSc at the University of Toronto. Harvard University granted her a PhD in Astronomy back in 1999; she now works at MIT as an astrophysicist. Still, she’s a Toronto connection in the rarefied world of exoplanet detection.

Professional Writing by DeHaan Services

DeHaan Services writes web site or advertising copy for clients. Our skills are demonstrated in online articles in Decoded Science and Decoded Pregnancy. That’s why we highlight these online articles on this blog page. My niche in Decoded Science is mathematics: both math theory, and how to apply math to practical problems.

Superscript and Subscript in WordPress

I needed superscript and subscript text for that Decoded Science article. The WordPress online “Visual” editor does not support those text formats, so you have to use the “HTML” editor and type the tags directly. (The “Visual” editor supports bold, underline and italic, as well as heading levels). Learn more about these formatting tricks in the writing tip in my “Preview of the Drake Equation” blog post.

If you’re looking for a compact telescope, Amazon carries the highly rated and well-priced Barska AE10100 Starwatcher 40070 Compact Refractor Telescope in Canada. It’s a portable refractor telescope with maximum 300x magnification and a tripod. The American version‘s reviewers noted that it is more suited to gazing at the moon than probing interstellar space. However the price is low, it’s sturdy enough for beginners to use without a lot of fuss, and is a good introductory telescope for beginners.

Thank you for reading about the Drake Equation, which launched SETI and SETI at home. Boldly search for alien life from the comfort of your home computer.
