I have taken a break from 5 Cool websites series due to my exams but now I am back again with this series, hopefully I will continue it for a long time now.

1. HowStuffWorks

HowStuffWorks, a wholly owned subsidiary of Discovery Communications, is the award-winning source of credible, unbiased, and easy-to-understand explanations of how the world actually works.

From car engines to search engines, from cell phones to stem cells, and thousands of subjects in between, HowStuffWorks has it covered. No topic is too big or too small for our expert editorial staff to unmask … or for you to understand. In addition to comprehensive articles, their helpful graphics and informative videos walk you through every topic clearly, simply and objectively. Check out an example link How Optical Mice Works.

4. Subscene

From all the best subtitle sites over the web, Subscene stands out. Use it once, and you’ll be hooked. Aside from looking great, it has an incredibly user-friendly and reliable interface, and offers pretty much all the subtitles you need.

Subtitles are grouped by movies or show seasons. You don’t search for subtitles, but for those pages. Once you’re there, you can scan the page or use a simple (Ctrl+F) to find what you need. Languages can be chosen by specifying a language filter and selecting up to three preferred languages. The filter will stay into account during the rest of this and future visits of the site. Thanks- Makeuseof
