Posted 14 Oct 2019 by Byron Leigh Hatch @ team Carl Sagan Post: Hello everyone, at some point, you got hooked on science, numbers and mathematics. Most if not all members of our team attribute this addiction to mathematics and science as a result of Carl Sagan and the wonderful series "COSMOS" Dr. Sagan's ability to explain science in a fashion that was very easy to understand created a huge interest in space from people of all ages and walks of life. If you have been 'touched' by Carl's words and wisdom, this is the team for you. We are NOT hardcore scientists, We are just people who have and will continue to admire the work of Carl Sagan and Ann Druyan. Some of our members earn 20,000 credits a day, others just a few. It's not about the credits, Its about the team, the memory of Carl Sagan, his wisdom and insight into the cosmos! join our Carl Sagan team and crunch to keep the Memory of Carl Sagan alive.

Error's while Computing ?

Posted 14 Dec 2010 by Byron Leigh Hatch @ team Carl Sagan Post: You're right. This number does have an unusually high failure rate of about 10% on Windows but not on Linux, and it's not the usual memory error. These larger numbers are pushing the boundaries of the siever. The good news is that the failures mostly happen after a few minutes of runtime so not much time is lost and that I have an explicit list of test cases to use in debugging. The bad news is that my plate is full right now, so it will be a few weeks before I can get to it. Thanks for letting me know! Hi Greg and hello everyone. I thought I would also report in. in case my computer (a Dell Precision Work Station) has information you need in your investigations of these computational errors. I'm also getting a lot of Computational errors. I'm not an educated person, but I love Mathematics and numbers, and so I want contribute some spare CPU cycles from my computer to your Project.

Posted 10 Dec 2010 by Byron Leigh Hatch @ team Carl Sagan Post: P = NP ? is it bad news for the power of computing ? update December 10 2010 Neo - (Project scientist) - at AQUA@home posted the following: Ah yes, that P!=NP "proof" was debunked back in August. :) There are a bunch of posts on a blog by Richard Lipton about it, along with hundreds of comments discussing the issues with the paper: http://rjlipton.wordpress.com/2010/08/15/the-p%e2%89%a0np-proof-is-one-week-old/ http://aqua.dwavesys.com/forum_thread.php?id=670#9283 |

Posted 10 Dec 2010 by Byron Leigh Hatch @ team Carl Sagan Post: We humans as a - multi-planetary - civilization The SpaceX Business Plan: Help Build a Spacefaring Civilization by Nancy Atkinson Universe Today Elon Musk - (born June 28, 1971) is a South African-Canadian engineer, entrepreneur and philanthropist best known for co-founding PayPal, SpaceX and Tesla) - Elon Musk - conceded that the space business world is an extraordinarily difficult place to make money. But that isn’t his main priority anyway. “The reason I’m doing SpaceX,” Musk said during the Falcon 9/Dragon post-flight press conference, “is that I just happen to have a very strong passion for space and I want us to become true spacefaring civilization and even a multi-planetary civilization. That is my goal for SpaceX.” ... http://www.universetoday.com/81570/the-spacex-business-plan-help-build-a-spacefaring-civilization/ http://www.universetoday.com/81570/the-spacex-business-plan-help-build-a-spacefaring-civilization/ SpaceX's Elon Musk with the Falcon rocket.
