ETCHNEW 2016:from CUSAT campus.

Demonstrating setup for showing how a material could be made invisible
Light is a form of wonder to all ages. Writers had written a lot about it, poets had sung numerous poems about it, scientists had tirelessly worked to explore about it. From Plank to Einstein, the definitions about it had made a new area to search about, for generations of students to come.
Recently I had a chance to visit ETCHNEW 2016, THE OPTICS FAIR held in International School Of Photonics, CUSAT.there was an exhibition about how lasers can be applied to several technologies.Here I would share some items which amazed me in terms of its variety and technological innovation. 
Data Transfer Via light (not WI-FI But LI-FI)
Demonstrator had two laptops at a distance and an equipment on which a small LED bulb is mounted. When we type something on one laptop, we can see a simultaneous blinking of LED bulb and appearance of same letter on the other laptop which is assisted by a photo detector.
CLOAKING a material or making things invisible.
Had you ever wondered if people could become themselves invisible and walk on this Earth, as in Harry Potter Film? This is a promising demonstration that predicts such materials that make things invisible is to come on earth.
Demonstrator had an arrangement in which he will show how using some principles related to light (refraction),a bottle can be made invisible.
SMARTPHONE MICROSCOPE
We are living in a world were smart phones take cares of all our duties.
Storing a library with thousands of books, paying bills, booking tickets.... this huge list goes on, this is yet another innovative concept in which smartphone camera is used as a microscope for research purpose, see smartphone is even displacing the microscopes in our science labs.

Love stories that touched my heart A beautiful anthology book, collection of heart touching love stories, the book is really worth reading.. We get a chance to know how young writers around India excelled in their writing skills to make their words really touch our hearts. The book is edited by Ravinder Singh the author of best sellers  'I too had a love story ' and 'can love happen twice? ' The stories unveil the unconventional forms of love, breaking our common views of love and relationships. Bringing a broad meaning of love into light, burning to ashes the belief that love is confined to only few romantic moments and the notion, love happens only in love marriages. The story I liked most is " a tale of two strangers" by Swagata Pradhan. Which portraited the childhood friendship drifting into love, the following pain and scare of separation. 'Heartstrings' by Dr Roshan Radhakrishnan, is yet another attraction, showing the eternal form of love,...

kebab stick and the little girl

"bhaiyya mujhe bhi chahiye" ( Brother, I also want) - she told us pointing the delicious street foods ready for breaking fast during the Ramzan month at Mumbai Ghansoli Darga street. A cute little girl, half our height kept patiently waiting, as my friend handed her the kebab stick.  "mujhe ek aur bhi chahiye" (I want one more) she did not walk away. He bought one more and handed her. she ran into a parking lot, not much lit by street lights.  I watched her as she stood alone in the dark and started eating it. She didn't look back, she did not care the whole world that made her eat it alone. #shortstory #mumbaidiary #hunger
