More than a year ago, I wrote a blog compiling lots of links to educational resources, especially mathematics. You may and should check it in case you have missed it. (My calculations show you have probably missed it.) Since then, I have encountered some more interesting websites. The topics these websites cover range from history to science. I have listed them in no particular order.


  •  Coursera - This is a terrific website. The most prominent feature of this website is that it offers well structured courses from the faculties of best universities. This is sort of online university where you take courses, participate in online tests and for a small fee, you even a get a certificate. The range of courses is quite wide.  My personal favorite.
  • OpenStax College - An initiative of Rice University, OpenStax College is a not for profit organization whose goal is "to provide free textbooks to students." This is a serious initiative and has been supported by many noted philanthropist such as Bill Gates and Warren Buffett. 
  • Faculti - Video talks by intellectual giants such as Noam Chomsky, Steven Pinker, Thomas Piketty and many more. Terrific. 
  • Open Culture - Very good site. Provide good resources/articles for just about any topic. 
  •  edX  - Online courses from various universities.

  • Intro Learn - Comprehensive resources from across the web
  •  
  • MinuteLabs.io - Cool science shown through multiple media.
  • Biology and Related  - At one point, I got deeply interested in biology and genetics in particular which made me scour through Internet and I found some very interesting resources. My personal favorite is Kimball's Biology Pages. Though I am still a novice in Biology, but I found this website to be the most elaborate. Some more listed below: -
National Science Foundation 
Oak Ridge National Laboratory (Not limited to Biology only.)

(Note that all of these are official US websites for their respective areas. This list isn't exhaustive and I have possibly missed out some websites. )

Tree of Life Web Project - The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history. (Directly quoted from the website.)

Recently I came across this REDDIT link which has many links to websites offering interactive programming features. Though I haven't checked those links, you may check them any way. You may also check this REDDIT link for gaming related software development. Similarly, University of Reddit offers 'courses' for topics such as film-making and other such creative stuffs. In fact, for those who like to keep digging and exploring, Reddit is a goldmine where finding gems is all par for the course. Even if you want to waste time, prefer Reddit over Facebook, you'll still be an idiot, but in superior ways and in a sophisticated sense.

Seriously. Once again, as I mentioned in the beginning of this blog, I had already compiled a list of websites in my earlier blog. Some terrific sites such as Khan Academy and MIT OCW have already been mentioned in earlier blog. Still, if you come to know about some terrific resources, let me know so that I may update the compilation.
