Are gravity (and star-system) simulators worth the $$$?
Ditto here, although I'm running Linux as well. (Win7 Home Premium was installed on the laptop; I installed (and use extensively) Linux Mint 13.) I have heard of (and have on my machine) Inkscape and LibreOffice (which is a fork off the OpenOffice code; fairly mature and VERY stable). As for...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
Sorry for the longish delay on my reply to this. 5-yr-old in house and I've also been a bit scatterbrained! In reference Trek, especially ST:TOS, I fully agree that the Silver Bird of the Galaxy's reasoning was a bit flawed, but then again, he was a cop when he originally wrote out the...- rdanner3

Graduate Size of fictional planet based on gravity and density
The only Habitable Zone "calculator" I've seen at all is useless for what I need; it only shows three very-general star types (basically, small, medium, super-huge) and is leaving me totally unable to figure out other critical data in re: the star classes of these star systems. Based on what I...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
In ST:TOS, the stardates weren't even consistent. Wasn't until ST:TNG that stardates were consistent enough to actually be useful for anything. (The "stardate" of a Captain's Log in ST:TOS was actually a random number. This has been confirmed by people who worked on the series (including several...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
Mass of the planet is discussed in one of the other threads I began. Basically, density is identical enough to Earth's that using that as a baseline works. While this larger planet's water percentage is only (IIRC, must check my resources!) 57% vs 78% for Earth, the ecosystem is very different...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
Regelis, for example, is a more arid world than Earth (with only 57% water area vs. Earth's 76-78%), while Trekala is probably closer to Earth in both size and general livability. Heck, it is even likely that the star the latter planet orbits is a direct analogue to our own Sun, albeit a very...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
What I need, really, is to be able to work out the size of the globes in question, the orbits of the planets, etc. One planet in my books, for example, has a gravity of 1.916g, and an orbital period of 1157.407407407 Terran days (which equates to 1000 local days (of 100000 seconds)). Another is...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
Without some idea of planet size (and therefore likely surface area) I could make serious mistakes regarding distances on-planet? And ditto for distances between star systems or planets. Some of the star systems are legitimate (and known!) systems within the Milky Way, so accuracy is highly...- rdanner3

News Air Purifiers are a Ripoff - Whirlpool ap51030k
The fact it failed completely after the first cleaning (and I followed very specific steps to correctly clean the unit top-to-bottom, some of which were not mentioned in the manual's "How to Clean Unit" section) turned me sour on the whole idea of air purifiers, to be honest. However, I did...- rdanner3

Are gravity (and star-system) simulators worth the $$$?
As a writer, this is important for me to know, since if they aren't worth the money to purchase (and many of them are indeed for-pay, rather than Open Source), I need to avoid mistakes. Currently looking at several programs, some of which I know are likely to be Windows-only. Since I...- rdanner3

Getting Fit: Shedding Pounds and Achieving Goals Together
White bread? UGH. Too much bleach in it. Whole-grain or whole wheat is much better. I do not even consider white bread unless there is literally no other choice. McDonald's? Won't go there. Ever. Too many artery-choking choices, very few relatively-healthy. And that doesn't count in the fact...- rdanner3

Graduate Size of fictional planet based on gravity and density
Yes, I have, but finding correct data on the different star classes (or an actually-working visual calculator!) has been interesting. Okay, that does make sense, insofar as I actually understand what you've mentioned. I would be incorrect if I said I understood all of this. :-) And I acknowledge...- rdanner3

News Air Purifiers are a Ripoff - Whirlpool ap51030k
Consider the fact that there are silent systems that are very highly effective. One such used to be made by (or for?) Sharper Image, but the one I eventually bought (the Ionic Pro) worked fine until it needed its first cleaning. Hasn't been anything except a very expensive tripping hazard since...- rdanner3

Graduate Size of fictional planet based on gravity and density
Given a planet of the same (relative) density as Earth, and a G-force on said planet of 1.916G, what is the procedure to determine the radius and surface area for such a planet, given it having only 57% water coverage? I will admit that I am working on this for a book series I started in...- rdanner3
