The First Lightbender

              “Light only travels in straight lines” said his teacher. Unsatisfied by the notion, it became of utmost importance to prove to that the statement is very unscientific and obviously untrue. Dr. Narinder Singh Kapany was the man who proved that light bends and can be bent on purpose, for which he is acknowledged as the ‘Father of Fibre Optics’.

                It is normal for anyone to think that the above depicted rebellious attitude comes from a science graduate trying to make his mark as a scientist. However, this thought came from a gifted youngster at his school in Dehradun, India. This marked the beginning of a series of experiments conducted by Dr. Kapany since his school days to prove that light can be bent as required. After completing his graduate degree at the Agra University, he joined the Imperial College of London and conducted various experiments relevant to his theory. He was recruited by Harold Hopkins, who was working on developing flexible fibres for medical purposes. Along with Hopkins, he developed the flexible fiberscope system using unclad glass fibres; instead of prisms as he did in his school days.  He could clearly see the application in the field of medicine for endoscopy and published a paper in the Nature magazine in 1954 titled ‘A flexible fiberscope, using static scanning’. Hopkins and another scientist, van Heel published papers similar to Kapany's. He completed his Ph.D. from the University of London in 1955. Kapany completed his new invention - the glass rod in 1956 using unclad fibers as opposed to modern optical fibres that use a cladding. Hereafter, he left for USA and promoted fibre optic technology and playfully quoted it as his ‘Indian optical rope trick’. He coined the term 'Fibre Optics' in 1960.

Dr. Kapany taught at the University of California (Berkeley and Santa Cruz) and Illinois Institute of Technology. He started companies like Optics technology Inc. and Kaptron Inc. in the United States; with the help of a local financial institution in 1960 and 1973, respectively. More than 150 patents are registered under his name including High Efficiency Light Transmitting Window, Fibre Optic Communication modules, Solar Energy Collector, Planar Hybrid Optical Amplifier, Blood Flow Indicator and Process, Apparatus for Coupling and Amplifying Light between Optical Fibres,  Photorefractometer, Fibre Optic Isolator and Amplifier and many more. His major contributions are in  Fibre Optics, Lasers and Diagnostic Medicine.  
                Despite his significant contributions to the field his name was not included in the Nobel Prize for Fibre Optic Communications. His name remains absent from most textbooks in India and abroad. Kapany has been felicitated with the Pravasi Bhartiya Samman and The Excellence 2000 Award. He has keen interests in sculpting, philanthropy and art collection and has created 40 sculptures which were displayed at various art centres throughout the Unites States. He made significant contributions to Sikh studies and promoted Sikh culture in America.

           At age 85, Dr. Kapany is the founder of K2 Optronics Inc.; run in conjunction with his son, Rajinder Singh Kapany. He is actively filing patents and working in the field of Optical Fibers. He lives in the Bay Area with his wife, Satinder Kaur; son, Rajinder Singh (Hi-Tech Executive) and his daughter, Kiran Kaur (Attorney and Filmmaker). His undying passion for science, art, religion and culture depicts the composition of a personality that defines excellence. Sikhism defines knowledge as light and he showed light is knowledge, reflecting the true Sikh spirit. A true Lightbender!

[Solved]2.1 Speaker Setting for Windows

 A lot of PC users have 2.1 speaker systems, but are not able to reap the benefits in later versions of Windows edition. Windows 8.1 onward, we have sound settings for stereo, quadraphonic, 5.1 and 7.1. When the 2.1 system is set to stereo settings, the sub woofer would have sound, but wouldn't function as it would normally. Bottom line, No BASS!! Do you want to know, how to set a windows 2.1 system in Windows 8, 8.1 or 10?

Lost Indian Culture

"We should never forget our culture.", is something you would hear from a lot of people in India. During this conversation neither the speaker nor the listener gives a thought about "What is Indian Culture?"                                A Wikipedia search on Indian Culture(East Indian) would define culture based on religions, spirituality, cuisine(food), arts, clothing(ethnic costumes), values, customs and traditions, lifestyle, languages, literature,sports and popular media. Not to be confused with native culture(As Americans still believe Columbus found the right island). However, this does not exactly fall in line with the subject. A closer look at the Wikipedia article would give two words - Aryan and Dravidian. There is widespread controversy as to whether - they are two different races, Aryans were immigrants and if Aryan is the name of a race. Practically, 80 % Indians(Aryan or Dravidian) have accepted the authority of Vedas and similar literature as the

Lost Indian Culture - II

I did break some serious beliefs in my first post and this one will drill deeper and clean a few more. The concept here relates to culture and religion. Basically, there are eight religions in the world - four originated in the Gulf and the rest in India. Most religions present in the west originated in the gulf and are called western or Abrahamic religions.                                           The four religions originating in India are called Dharmic paths, as per Wikipedia . This is the most common mistake made by all Indians as no proper explanation is offered on what Dharma and Pantha are. Aptly, Indian religions should be called Panthas (Paths). However, that isn't the purpose of this post. Indians are believed to be very cultured and religious. Modern Indian citizens tend to think that religion divides, spreads exploitation and is fascist. But neither the religious, nor the self proclaimed secular know what our religions and culture teach us. Negligence to s
