Forest Fires – a Scientific Angle


I watched an interesting article about Forest Fires about an year ago. Couldn’t find a better place to share this than my own blog.

Start


I have always wondered at the ecological balance maintained by nature. For that matter nature itself is full of mysteries and wonders yet to be explored. I had always thought forest fires are caused either because of human involvement/negligence or due to heavy lightnings. But I recently found a new and interesting cause for this.

StartWe know drizzle on a sunny day leads to formation of a rainbow. This is because, every single raindrop acts as a prism that refracts the sun light into seven colors. But I never knew these rain drops are also dangerous. Actually these rain drops are capable of triggering a forest fire. Now coming to the science behind this happening. Everyone knows the refractive index of the water drop is 1.33. This is the base for the whole story. The water drop can actually act like a prismatic convex lens(magnifying glass). This lens can intensely converge and focus sun’s rays upon dried out vegetation/leaves, which will in turn get ignited and there starts the whole movie. We can witness yellow dots near every droplet in the picture above.

Ideally in most of the cases the water drop gets evaporated before it could initiate a fire. But a group of water drops intensely focusing on a dried leave could achieve this.

Facebook syndrome


I have always thought about writing a post on “Facebook Syndrome” and to tell u the truth, I am no exception to this. Facebook has victimized crores and crores of wise men,women,boys, girls and children too.

It is not fair just to quote the Negative sides of Facebook. So lemme start this post with some of the Positive sides of it.

Everyone will accept, If I say Facebook or any social networking site for that matter, has literally shrunk the world. People who are total introverts in reality are making loud noise in the virtual world. In fact, a friend of mine who never opened his mouth in college is now writing great posts in Facebook and socializing like anything. In fact I then understood, introverts have a great analyzing skills and capability after seeing his post. It is just that they are keeping things within them. Now Facebook has brought out his hidden talents and you can stay connected with all your friends.

StartNow to the darker side of it, the list grows like Pinocchio’s nose. I have studied about the principle of induction of charges in my 5th or 6th standard classes and to recollect it again,

“If you try accumulating +ve charges on one side of a dielectric plate, it automatically induces negative charges on the other side of it.(even if you don’t wish that to happen)”. Same thing is applicable to this. Good things never come alone.

The main bane of Facebook is its ADDICTION. Before five years, the first hit page after opening the browser was Yahoo or Google. But now it is Facebook. People get themselves lost in this limbo. They don’t have time for any sort of physical activity and in fact they are secluded from the real world relationships and emotions. They can just boast on the count of friends they have but in reality they are devoid of good and true friends.


People are expected/forced to talk about themselves which is not liked though and this has increased the level of obsession. Now people snap photos only for posting them in Facebook. A month ago, I went to a nearby browsing center for getting my irctc e-ticket printed. I was just waiting as every system is occupied. It is then I saw a five year old boy logging into his Facebook account. But to my surprise there were no friends added to his profile. Then he opened farm ville from his apps and started playing. This is the condition that Facebook has pushed us all to. I am not sure whether to feel happy about the reach and access of technology or feel bad that he is missing all fun around with his friends. But one thing is sure that these browsing centers are minting money from these boys.


It is nice, if you treat your fb account like your any other mail accounts and access them once or twice a day. We should really weigh the values of human emotions, stop being secluded and try to come out of this illusion of virtual world. we should really tick a Count down timer in the mind as soon as we login to the fb account. This will really save us a hell lot of time to do some productive work.
