I have read a few scifi books and I am amazed of the scientific terms used by the writer and the detective stories way of investigating the crimes with a police feel of things.

Im not a cop nor a techno centric guy but I want to learn how to write them. Any ideas?

Science Fiction is nothing more than "Fiction in Shiny Metal and Vinyl drag" yet for all of the metal and plastic it does have an objective-- to look at life, politics, philosophy and / or human experience from a different view point. Sometimes that viewpoint has a message sometimes it is "just for the fun of it"...

Some times SF is a game of "what if..."ife or history was somehow different...

Read the hard cover version of "In the Country of the Blind by Michael Flynn (I picked up my copy on e-Bay). In the hardcover of that book there is a after word which is a updated and revised version of two "speculative science" articles the author wrote for Analog magazine entitled "An Introduction to Cliology". See: http://books.google.com/books?id=2MrNykSR2WkC&pg=PA477&lpg=PA477&dq=An+Introduction+to+Cliology&source=bl&ots=Ma53rbZ7n2&sig=MxK_tir9rBAbvm-SnHF99MzO8cc&hl=en&ei=Vx0TTsqTIqX20gGWg4j-DQ&sa=X&oi=book_result&ct=result&resnum=4&ved=0CC8Q6AEwAw#v=onepage&q=An%20Introduction%20to%20Cliology&f=false

Cliology is the "science" of predicting the future by extrapolating from the past (Putting Isaac Asimov's "Psycho-History" on nearly solid scientific ground... if you're not familiar with Psycho-History read  "The Foundation Trilogy" by Isaac Asimov).

SF writing is not that hard... you can get word generators or star system creators...  those are just facilitators of your objective-- the story. Firstly you have to have a story and characters that people want to read about.

Sometimes science fiction doesn't  have to have funny sounding words or shiny metal... sometimes they take ideas one step further. for example ""Falling Through Reality"is a story about what it might be like to fall into a parallel world.

[See  http://groups.google.com/group/alt.cyberpunk.chatsubo/msg/a6b7fce05c6e5241?hl=en&&q=falling+through+reality  which was published in The ACC anthology 2 [commercial break: http://www.accanthology.com/buy.html ]]

Yes there is a logic and sets of rules and that is why you do your foot work / research reading.

Sometimes SF is nothing more than romance novels dressed in Shiny or rough leather clothes (The whole Liaden universe by Sharon Lee and Steve Miller and the Dragon Riders of Pern universe by Anne McCaffery are both "romance" SF)... but plot and characters hold those universe together quite well (Some of the best entertaining fiction I have read!)

Sometimes SF is a political treatise: 1984, Brave New World, Animal Farm, almost all of the "major novels" by Robert Heinlein,  all of the "Co-Dominium" noves by Jerry Pournelle have political agendas.

Sometimes SF is a parallel mythology / history which gives the story a whole different skew on life, history, and reality (see Jaquiline Carey's massive SF/Fantasy/Historical Romance/kink-fest Kushiel series).

So you have some home work-- some background reading is a good place to start:

I really should browse through the forums more often XD

I love sci-fi, and I love writing it. There really is alot of different ways to approuch sci-fi, imo. It depends on how realistic you want things to be. Technology can be whatever you want it to be, it doesn't have to fall into normal laws of reality. It is science "fiction" after all

Some stories throw alot of techno bable around, using big words or words you've never even heard of. This is usually done to make it feel more sci-fi, leaving the viewer/reader slightly confused on what's being talked about while at the same time getting a sense that everything is high-tech. Research pays alot in this area, as there's usually some big techno word for something basic. For example, you might get someone explaining a situation to one character in a sciency way, and then that character says "in english please". Then the situation is explained in a more "down to earth" way that the viewer/reader can understand

The things I personally have researched are things like distance between planets, sizes of planets, and how long it would take to travel to different planets at light speed. I've also done research on DNA and nano technology, because my story has alot of that involved. You want to find where reality is, and how much of it you can twist and still make it seem believable, while coming up with your own new ideas that are far from reality

Immersion is important as well, if you're sucked into the story, you tend to just believe things that are completely unbelievable. You don't always have to explain things in great detail, and sometimes it's better not to. It's not always easy to pull off, it can sound funny or stupid, while other times you wont understand a single thing said but for some reason it sounds believable

As for detective kind of work, that's kind of a different subject. You have to be really creative in this area. When it comes to solving mysteries, you have to keep the reader just enough in the dark to keep them guessing but enough in the light to keep them interested. I would say this kind of writing is more difficult than sci-fi writing, but it can also just come fluently as story progresses

After these two long, well-written replies I'm almost embarassed to suggest this, but simply watching CSI, Bones and similar shows will give you a decent grounding in the current crime-detecting technologies and methods.

One word at a time!

Sci-fi is as it it-fiction.

true science fiction should come from your own thoughts.

never mind tring to write the perfect ground stated word's or guidelines.

your story is all in your mind so write it as you see it not how you expect others to see it.

take for example Tolken-did he meet wizards and hobbit's? did he study to find out fact's? no he used his imagination
