I am hoping that mostly all of us know about Khan Academy. It is one of most successful source of virtual teaching an learning. Right now, over millions of students or even grown up adults are part of this amazing website that educated people in a very interactive way. Real life learning is definitively awesome, but some advantages that virtual learning has over real life learning is that:
– You can go on your own pace
– You don’t have to feel embargoes of asking the same question again and again. Just rewind the video.
– You don’t have to sit there and watch it a specific time. It’s at your own will, if your responsible and interested enough.
– If you don’t completely understand from the virtual source, you always have the real life learning to refer back to with some extra knowledge.
Khan Academy is that very virtual learning course. It in particular is very entertaining and lively compared to other virtual educational videos, simply because the voice of the tutor is always very enthusiastic and also because he tries to keep the humor alive in the video too.
Khan Academy began when one person, Salman Khan, tried to help his cousins in Maths or just for their sake made a video about it and uploaded it n YouTube. The feedback he received was amazing. He got letters from people, enthusiastic and thanking YouTube comments, people actually started watching his videos for their preparations, etc. From there he got an idea of Khan Academy and started this amazing virtual source of education.
In this video Eli Periser is informing all of us about how social and news websites like Google, or Facebook, or Yahoo News use algorithmic values and calculations to self determine what does the person looking at the screen actually want to see. They would cancel out any adds, or web links, or notifications which they presume is least opened by the user, hence just an unnecessary piece in their research and doesn’t hold any value when in fact that very page or link might carry a significant purpose to the user. It might just be that the user has not been able to use that piece of information within the time period the website thought that person doesn’t really want the page at all.
Eli Periser also talks about how these actions of the websites are restricting people all around the world from the knowledge they should have about the world. Internet was invented for the social communication, or connectivity of the wold. Now, however, that very reason is at risk as internet now is only giving us the information or a source that we want but not what we need. This would just end up making people around the world just anonymous about what’s happening around them.
This is not an official music video, but it is on i-Tunes if someone is interested. It is a parody “revenge” video that a very renowned channel of YouTube made in the year 2010. As the title implies, it is a Pokemon theme song parody, including a revenge in it, as their previous parody video was removed due to copyright reasons. I like this video mainly because I like Pokemon, and also because I find it hilarious.

The Sixth Sense is a revolutionary invention done by Pranan Mistry. He made a device that “brings you digital life to the real life”. It allows you interact with digital appliances using real life body movements. I think this is a very geniously thought because, as Pranav also said in his video, it can be great tool for physically unstable people. They can use it as a system of communication. Also it is also a very attractive technology.
