SETICon last call! | Bad Astronomy

Posted on by

setconlogoJust a reminder: this coming weekend (August 13 – 15) is SETICon, a convention where science and science fiction meet. You can read all about it in my posts where I announced I’d be there, and a followup. It’s still only $35 for the whole weekend, though there are options if you want to participate in more events.

I expect this to be a lot of fun. A pile of old friends will be there, and the talk lineup looks really cool. Scientists, astronauts, plus actors, writers, and more from Star Trek! Also, I’ll be playing — and singing — with Rock Band. Yes, you heard me. If you’re in the Mountain View (southern San Francisco bay) area, then you really should come.

Space Station EVA Unable To Remove Failed Ammonia Pump - More EVAs Ahead

"The next spacewalk to complete the removal of a failed ammonia pump module and installation and activation of a new pump module on the International Space Station's S1 Truss will take place no earlier than Wednesday. Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson completed the first spacewalk to remove and replace the pump module at 3:22 p.m. EDT Saturday. As the result of an ammonia leak in the final line that needed to be disconnected from the failed pump module, the day's tasks were only partially completed."

Ungrounded System Earth Fault Protection

Take a case where a power transformer with star-delta configration star side neutral is impedance grounded and delta side is load side. If fault occurs on bus (load side) diff. relay of transformer gets tripped.what are the means available to detect earth fault protection on delta side?

Can you please help me? I am currently writing my dissertation on STATCOM Control. I would like to ask what is the methodology of replacing the DC Voltage in the STATCOM input with a DC Capacitor. The simulations are run on the PSCAD software.

This is the first of what I hope will be a new series on this blog, providing an overview of key topics that I find myself drawn to again and again.

The idea for this has been germinating for a while now, not least because it seemed a shame that old posts get forgotten in the mists of time. Much has been written about the importance of context in modern science journalism – providing the necessary background so that readers can put new discoveries in their broader context. To achieve this, I considered doing topic pages like those that many newspaper sites do, but I (and others) find the automated nature of these pages to be ultimately unfulfilling. You need some sort of human editorial control to make them useful.

At a recent blogging talkfest, someone in the audience asked about whether blog posts could be aggregated into an educational resource, like a textbook. The idea seemed promising but the disparity of style across different blogs, and the rubbish quality of most blog search engines, makes this a difficult venture. But these primers, hopefully, address these shortcomings – the idea is that I will take old material and re-edit them into a coherent tour through an exciting topic. The tour will take the form of an online slide show, as powered by Discover’s cool slide technology.

Let me know your thoughts.

(PS – Credit to Ferris Jabr for suggesting the name “The Yong and Short of It. In the end I went for something simple, but I might use that in the future ;-)

What is all that noise coming out of my computer?

Kate asked me and I told her that it was the electrons going around the corners when the wires were bent too sharply.

She didn't beleive that either.

My old Chev. truck is having one of the few illnesses ever afflicted.

It won't idle. It just dies every time you do anything but run down the road. Otherwise everything is fine. Starts like a great.

I am thinking of 'scoping the idle speed motor wires, but I don't know w
