You need to know lots to get started but here's a bit about filters: http://www.telescopes.com/telescopes/howdifferentfilterscanbetteryourviewarticle.cfm

I've turned my previous link into a pdf for you to download. Finding Polaris, the North Star - McWiki.pdf

Have a look at this: http://www.themcdonalds.net/richard/index.php?title=Finding_Polaris,_the_North_Star

Thanks to everyone who has emailed, Tweeted and texted me about the "artificial bright light" seen on Mars. And I'm so sorry to disappoint all the folks who were hoping for aliens, but what you see above is just an image artifact due to a cosmic ray hitting the right-side navigation camera on the Curiosity rover. If you do a little research, you can see that the light is not in the left-Navcam image that was taken at the exact same moment (see that image below). Imaging experts agree this is a cosmic ray hit, and the fact that it's in one 'eye' but not the other means it's an imaging artifact and not something in the terrain on Mars shooting out a beam of light. Update: according to Alan Boyle at NBC News, NASA imaging scientists think it could also be either a well-placed flash of reflected sunlight, or light shining through a chink in Curiosity's camera housing.

Only if the infected file is used again. It's inert otherwise ...it needs CPU time to do anything and if it's not in the working domain of the operating system it's useless, If the instruction is not in the new image to fetch certain files to initiate the malware process the machine will run sweet. Re-infection is not necessarily automatic ...unless it's in the boot partition in W7 then it can recur.

I use periodic re-imaging with my customised OS image if I sense any problems and my working machine also is always running spot-on doing this. Data is kept separate.

Yes, your post prompted to have a Google and it seems the SNR sets the starting baseline for overall range of contrast ...the lower you can get the noise the wider the contrast. and sensitivity. I found this article on image noise quite educative. http://www.cambridgeincolour.com/tutorials/image-noise.htm

Where there's a will there's a way ...regardless of what one has in one's hands. Expensive systems give you sharpness and resolution but that may not be important. Equipment and utility restrictions force one to think in ways that having everything may not ....necessity can be the mother of invention and lead one down creative paths one may not otherwise consider. When you cut through the crap, all a camera is is a box with a piece of embedded glass where one can govern the duration and intensity of an exposure ...and that's it. The rest is just for ease and convenience. If one is interested in photography as art the camera is no more than a means to an end and the quality of one does not define whether one can do art with it or not. The point I'm trying to make is that the only limit is oneself and not one's equipment. Poverty has taught me much .

Don't do torrents, download pirated software or porn and you've probably removed 99% of potential malware vectors. Knowledge is the best antivirus.

As long as a 'point and shoot' has manual aperture and exposure control over-ride, all basic creative options are available...the only difference is the photographer has to use his own brain and not the camera's. "Photography" is not the preserve of good equipment, it is that of a good visual brain. David Bailey was once asked what cameras he used and he replied that he would use any thing you gave him ...changed my whole attitude forever twenty years ago. After reading that I stopped hankering after that dinky do-it-all Olympus OM4Ti. A person seriously desiring to improve their photography would learn quite a bit about the thought and process of visualisation and subsequent image capture from reading Ansel Adams' The Negative.

Energy is a property of things and does not exist independently ...just like life or consciousness.

Movement of the foetus in the womb, amniotic fluid density, rate of growth and final size influences finger ridge formation so the chances of two people being analytically alike in this feature is probably vanishingly small I would think.

If people are offended by such things they shouldn't post on a science site. He knows the score anyway ..par for the course.

Consciousness is an emergent effect arising from interactions within certain arrangements of matter so - logically - matter came first. Anything else is religion. If you think consciousness is not organically derived drink a few big bottles of whatever you fancy and tell me your consciousness is independent of your body.

As long as your happy that's all that matters. Happy playing.

Glad you got it sorted. The resolution on yours is not good when expanded though. Try choosing Bitmap rather than Picture when you Shift + Edit to bring up the Copy Picture command in the Edit menu after highlighting the picture in Excel. Or did you save as JPEG instead of PNG?

The Open Office looks better than Office 2003 as it's more modern and for what you want to do is as easy as I wrote it. Just post if you get stuck.

Also I've read the source wants to be as compact as possible to improve separation of the colours. Probably a car headlamp -type bulb.

I got it to work in Apache Open Office which is free …method is slightly different. Install both programs first if you want paint.net as well: http://www.openoffice.org/download/ http://www.getpaint.net/ Open the spreadsheet in Open Office Spreadsheet (Calc). You first need to convert the .xls file to ODF Spreadsheet (.ods) by clicking File > Save As > Choose ODF Spreadsheet > Save. Then highlight your desired cells for your image(s). Right-click on the highlighted area and select Copy. Open an image editor and select Edit > Paste. Save the image in your desired image format. Paint.net is my usual editor and free.

Intelligence is born, wisdom is acquired.

If that's what you meant then yes.

No, I clicked More Reply Options > Go to Attach Files (bottom of text input box) > Click Browse (Select file) > Click Attach This File > Click Add To Post Is it Libre Office?

Which Excel do you have? This was done in the 2003 version. Highlight your target cells > Hold Shift and click Edit (top row) > Select Copy Picture > Select Bitmap > Click OK. It is now on the clipboard. Open a picture editor like Paint or Fastone Image Viewer or some such and click Paste in the Edit menu. Click Save As in the File menu in your preferred image format. PNG is good for graphic images like yours.

See if this works:

'Nothing' is an accounting word used by someone to describe the absence of something....it's a concept which resides in a mind but does not exist outside of that mind..
