Kerbal space program price brain1/9/2024 Ideally, you should be using a compiled language for this because of the indeterminate end conditions on the loops required when using a converging process, but they are often too tedious for anyone to sit down and do the coding. Anything written in simple Matlab should be easy to make work in Octave, which is open-source. That iterative procedure is not necessarily impossible to do in Excel, but it does immediately mean that you're into the area of math where you ought to be using something better than Excel. Luckily, it (in practice) almost always converges very quickly using a standard approach and a standard initial guess. That equation is transcendental and must be solved iteratively. The solution is not in fully explicit form however, because of Kepler's Equation, which relates time to a body's position along the orbit. With this simplification, there is a known solution to the trajectory. The primary body is the sole source of gravity that is considered when computing trajectories of any secondary or ship. Just so people know, the Kepler Problem refers to the restricted two body problem, which is the basis for all of the game's orbital mechanics. Best of luck to you in finding your new scope/binos! There's a ton to know, but to me that's part of the fun of the hobby. Read reviews of telescopes in your price range, browse astronomy websites for tips on how to observe, how to use the scope, how to figure out magnification/field of view/limiting magnitude/etc., and how to keep from doing something stupid like cleaning your optics with a paper towel. To tell you everything you really ought to know about telescope hunting and observing would be to write a very thick book. Observation is a skill, and so far I've found it to be one part knowing what to look for, one part knowing how to use your scope technically, ten parts dark adaptation, and ten parts patience. When you find the Eagle Nebula, you aren't going to see this:, you're going to see this: However, you will be AMAZED at how much detail you can actually get out of a faint fuzzy image like this if you learn how to observe. Know what they are! Manage your expectations. There are lots of add ons depending on your type of scope, as well. While they aren't strictly necessary, they are much more convenient than having to have your computer around to help you find planetary nebulae. Also, don't forget to factor in the cost of the necessary accessories! Your scope is useless if you don't know where to point it, so you'll have to either get some star maps or software to be able to figure out what's up there when it's dark out and where to find it. Here is a link that helped me when I was buying my first scope: (I ended up buying binoculars until I was sure I liked going out enough to spend much more for a larger scope). not the people selling the thing!) to get a good idea. There's no way you'll be able to figure out if your scope is a lemon or a pearl until you get it out and use it yourself, so you're going to have to read lots of reviews from independent sources (i.e. However, it does have to meet some basic standards of quality. As a rule of thumb: The best scope to buy is the biggest one you can afford that you will feel like taking the trouble to set up and use frequently.
