Jay's a celebrity now!
Apogee's Newsletter #150 is out, and our own Jay "CenturiGuy" Goemmer got his website mentioned. An image of his "Prometheus" design stands out...
Way to go, Jay!

"And now, for an encore performance..."
Quote:
A couple of months ago, I sent a bug report to Tim Van Milligan and Paul Fossey (hereafter known as "The Rocksim Guys"), and included the URL mentioned in the article. TVM sent a reply e-mail to myself and IIRC John Manfredo, who's the current editor for "Peak of Flight," mentioning it as a possible website to feature in a future article. So I've been *waiting* for it to show up for the last 3 issues! http://www.apogeerockets.com/educat...wsletter150.pdf I was slightly disappointed that my Estes Wolverine BT-55 upscale wasn't pictured in the article, but thought the selection of my "Tau Zero" and the "Pometheus" [sic] was pretty cool! And Craig, I *have" been working on a preliminary "hand and torch" design for the "P's" fin decal. Bill thought it was pretty good (*I* think it's pretty shaky), but wondered why the heck I was holding a torch, when just incense should do the trick of "clearing the air." Anyway, thanks for the congratulations! It's nice, even if I *am* playing to a small, intimate (but very supportive) audience. And if I can work it out successfully, below you'll see a preview of the aformentioned decal. Cheers, --Jay |

Now it's looking like I imagined it would... The "hand" seems OK to me (better than I've ever done...); the "torch" needs to look a bit more Greco... A "fluted column" appearance, with some sort of "grape" motif around the upper rim... Draw it large, like 18 x 24, to get the details; most of that will disappear when it gets reduced to 2 x 2 or smaller, of course, but you'll be surprised at how much it will improve the final image.

Jay, Is that "Tau Zero" as in Poul Anderson's novel "Tau Zero"?

Poul Anderson's "Tau Zero?"
Quote:
Yes, indeedy. The initial working name was "Biff Pau" (a horrible pun on the "sound effects" in the 1960's "Batman" TV show), and I liked the "au" because of the Centuri "Taurus." I haven't read Poul's book "Tau Zero" in years, but an astronomer friend of mine from the local observatory told me (as well as I can remember ), that the closer you get to traveling at the speed of light, the closer that the value for the Greek letter "tau" gets to zero. So (I *think*) that if you get to "Tau Zero," you're actually travelling at lightspeed. So yes, I borrowed the name from Poul's book. I've been especially enamored by his novella "Epilogue" (which I first encountered in the collection _Time and Stars_ 20-plus years ago), and I like lots of his other earlier works, too. In other words, "You caught me!" Cheers, --Jay |

"YOU can be an Art Student!"

I don't know if I'll go as large as 18 x 24, because I have to fit the pictures into my standard-size scanner, but 200% of the final size seems like a good place to start. ;-D Thanks, and cheers (and sorry I have to learn how to draw "more gooder-er" first), --Jay |

I wasn't trying to catch you, I was more trying to discover another connection (besides rocketry) between you and me, via Poul Anderson's science fiction. I used to read every one of his earlier books I could get my hands on at the local public library, and "Tau Zero" was one of my favorites, even when I read it as an adult, years (or decades, even) later. I think I read most of his later novels as well. But you're right, that's what the tau refers to. It's this: tau=sqrt(1-v^2/c^2), unless I'm totally mistaken, where v is your speed and c is the speed of light. As you approach lightspeed, the ratio v^2/c^2 approaches 1, so the value of tau approaches zero. In the novel, something went wrong with the ship's drive and they were unable to stop or maybe even slow down, so they made the decision to keep accelerating... and they kept right on going until the universe collapsed and the next big bang happened. By that (shipboard) time, I think they got the drive fixed and were able to slow down and finally land somewhere. Btw, and to get slightly more on topic, I like the looks of your Tau Zero as shown in the Rocksim image!

I only have the version 5 free/evaluation version. I had the v8 evaluation version, but it expired. But if you have a parts list or three to pass along, that would work! Btw, I notice that I didn't use ANY emoticons in my previous post... which, along with my writing 'style,' probably makes me sound more serious than I meant to be. And I'm using the word 'style' very loosely!
