World is a small place - Know about the '6 degrees of separation'

Billions of years ago, life on Earth started in a primordial soup. With the single celled organism, life eventually sprang up in water. Later, it evolved into creatures living on land, until we, the most intelligent (though I believe as most complex) found our mojo & began to rule the planet (& hence destroy it). Well this blog doesn’t speak about our wrong doings on the Mother Earth but is on an interesting thought put forward by one of our own kind. Since the origin of Life can be traced to a single organism, it is pretty much self-evident that all of us are somehow related to one another. But how close are we actually? In the sense, if you have to reach to another unknown person somewhere at the opposite side of planet, will you be able to reach out to her/him? If yes, how many threads have to be cut to reach the person holding the fleece?  Continue reading to know more..

The history and science of fireworks. Diwali Special !!!

“Uncle, why is this ‘Anaar’ giving red and green color light, why not some other color?”, asked Aadi, my friend Vijay’s 5-year old, who is a bundle of joy and child curiosity. We were celebrating Diwali in our society in Hyderabad as we could not go to our respective hometowns this Diwali. Someone in near vicinity was lighting up an “Anaar”, the flower pot or the fountain cracker, which was emitting stars of red and green color that fascinated Aadi. Firecrackers are age old tradition across the world. For many, firecrackers are an integral part of Diwali celebration. Let us know a bit more about firecrackers, their history and try to find answer to Aadi’s question. Firecrackers and their history: Firecrackers originated in China around 200BC, initial versions of firecrackers were made of a special type of bamboo which will explode on prolonged heating producing a ‘bang’ sound. Firecrackers in Chinese are referred as “ baozhu ”, literally meaning exploding bamboo. Aft...

What is the difference amongst Perfume, Eau de Perfume, Eau de Toilette and Eau de Cologne?

"I am looking for a good perfume bhai", said Kushagra, my younger brother. "Perfume? But why..since when have you started buying these stuff?", I queried him. "Since the day I have started cycling & any-which-ways the sweltering Faridabad heat demands one." "Ok..Which deo are you looking for?"  "Not Deo bhai, but perfume. Technically speaking Eau de Perfume. You really don’t know much about these na. Maybe you can write your next blog on the difference between Eau de Perfume, Eau de Toilette etc." said Kushagra correcting me. So here it is. My next blog on the sweet topic of fragrance. How is a Deodorant different from Perfume? While both Deodorant and Perfume create good aroma around, there is a major difference in the application, function and composition of the two. So to start with, let us understand the reason of generation of bad smell. The reason we emit a foul smell is attributed to the doings of bacter...

Is Spiderman's web really that strong? Know more about spider web and spider silk

“You guys have started to pick up some interesting topics lately”, commented Shikhar in our college whatsapp group in response to our last blog post on how lizards manage to cling and move on walls. While the post, due to obvious reason of being about lizards, made few of our readers go ‘eww’, Shikhar and few others found it really enlightening. While we were thanking Shikhar for his kind words, he asked a question. “Is the spider’s web really as strong as they show in the spiderman movies?”. Well, I told him, that I will find that out for you. And here I am, fulfilling my promise. Spider webs are a common sight around us. Small webs made by spiders near the corners of walls and ceilings. These webs are multipurpose device created by spiders sometimes to protect their bodies and eggs, but primarily to catch their prey. However, there are few species of spiders who do not built webs at all or catch prey using other methods as well. Spiders (along with few other insects and la...

How is a Lizard able to move across the ceiling without falling ?

'Is the box heavy? Should I get it down?', asked my brother Kushagra, with a wry smile. Though younger, he was well built while I was the slender, skeletal one. For good reason, I was given a nickname 'Hanger'; t-shirts just hung down on me. Well that was when I was in 5th standard. I wish someone could call me 'Hanger' today. 'Don't try to be a hero. Will give you a choke-slam, then only will you understand my power. Let mom & dad go, we will have the WWF fight and I will show you who is the boss', standing on a stool, I looked down at Kushagra, my eyes sharp gazing into his with raze.  'We will see bro, first you try to get the carton down'.  'Ok. Be quiet. Let me do my work'. Standing on stool, as I pulled the carton from the attic surface, I felt something slithering on my hands. A loud scream followed when I realized that a lizard had jumped out of the carton, onto my hands, and was moving so smoothly towards my...

India doing well at games that are brain child of an Indian. Read to know about history of Asian Games.

Swapna Burman , a name that was hardly heard of a week ago, is a popular household name now and a name that means national pride, and a story of fighting against circumstances to achieve success. Manjit Singh, Jinson Johnson, Neeraj Chopra, Arpinder Singh are few among many more such champions who have inspiring stories of success despite adverse circumstances. That’s what sports do best, bring out the real-life champions, who not only excel at their discipline of sport but also are great fighter and exhibit exemplary perseverance when conditions and circumstances do not favor them. All they need is a stage to express themselves while the world watches. The 18 th edition of Asian games provided that stage and revealed a new generation of Indian sports-persons, who are the new generation role models. As I write this, the closing ceremony of the Asian games is about to commence, and India for sure will be a proud contingent. Asian games , the quadrennial multi-sport event ...

International Space Station: The most expensive single object ever constructed

'Are you able to see that star-like glowing object coming out from behind the clouds?. That…..is the ISS', Rajarshi's eyes gleamed like a star as well. 'Seriously? That really looks like an another airplane', said I, gazing up in the not so starry Bangalore night. 'Han bhai, that is the ISS. It doesn’t flicker like other plane's light and travels much faster', the gleam in Rajarshi's eyes too wasn't flickering.  Raj (short for Rajarshi) is my ex-roomie and an avid star gazer, a reason for which he is also known as 'Star Uncle' amongst kids in our society. He had summoned all of us to be at terrace exactly at 19:30 hours; as at 19:32, ISS was to pass directly over us. We, quite fascinated by Sandra Bullock's Gravity and later McConaughey's Interstellar, were really excited to witness the ISS, when Raj told that it can be seen from our naked eye. And finally, the vision of the object moving high up in the sky, left us thrilled...
