Gadgets are available that people can wear for lifestyle applications. For example wearable gadgets from Jawbone, Nike, Garmin, HD Pro, and others that users can wear for monitoring running performance, sleep, health, and so on.
As these gadgets become prevalent and varied then they are going to generate lot of data. The data generated is currently used for self use for the most part. But what if the captured data can be used in real-time for others to experience the situation or moment ?
An interesting invention by Pranav Mistry, unveiled at TED talk in 2009, aims to use physical gestures when interacting with digital world. Later he experimented in overlaying digital world on physical world. Pranav was a pioneer and an original innovator as one can see the power and promise of the concept from the demonstration at TED talk.
While a product based on his invention has not appeared in the market yet it is still a possibility for a version of Sixth Sense to be part of our lives in future.
What this post speculates is on the possibility of sharing physical world in real-time with others using digital technology. It is a Sixth Sense in a different sense. Read on…
A concept already in vogue in our society. For women fond of having children but who can’t use their own womb, for medical or other reasons, there is choice made possible by advances in medical science. Could this example lead to others ?
Imagine you love Yosemite and have been there during different seasons and you are simply in love with Yosemite.
Or you have been to the beautiful city of Istanbul and taken boat trip on Bosporus (one of my favorites and highly recommended activity in Istanbul) and like to relive that moment later time in your life. How could you experience at least few minutes of that boat trip sitting right in your home?
The examples are endless – see Times Square, Hawaii, and so on.
When you are bored or stressed out from work or life you may wish to be in places you have been in the past and relax. It is like meditation or Yoga for you in terms of lifting your spirits but only if you can experience it.
If it is once in a month and if your favorite place or places are all nearby then may be you can relive by actually driving up there. But what if you like to relive past experiences few times or even every day? What if you are not able to travel at all? What if you need to relive now because your mind feels like it is ‘now’ or ‘never’.
Any time you wish to relive in Times Square , Yosemite , a trail to Everest base camp, you can bet that there are some people already there at that very moment. So why not see and experience those places using them?
Obviously, to relive past experience one needs input from five senses. However, the most important senses are eyes and ears. So why not start on a small-scale first by renting those sensors from someone who is already at a place you wish to relive?
By renting some ones eyes, you can experience that remote place as that person is seeing. You are there as an invisible object and as a shadow.
When you are shadowing someone by renting their eyes and ears there may come a point or moment where you want to touch and interact with the distant world that is being projected for you. For example, imagine you are one of those that find relaxation in visiting malls and shopping over weekends or other times. Now, consider that there is some constraint holding you from going to the mall but you really want to be there. What you could do is simply rent eyes of someone who is already there. Once you rent, you could be in Macy’s or in whatever shop the 1st person is going in.
At some point you may like an item you see in the shop and you like to interact with it – perhaps pick and feel the cloth quality. If you like it the next logical thing is to buy. This is where r-commerce (remote commerce or shall we say s-commerce meaning shadow commerce?) applications may be possible in future. You like something you see through the rented eyes and you want to make purchase.
More use case for Rent Eyes
Other use cases where renting eyes might be useful:
watching sports : rent eyes of those sitting in the front row or special areas
adventure : biking, racing, skiing. Imagine you can rent Michael Shoemaker’s eyes and experience race car driving
shopping. Just rent eyes of some one already in Macy’s and finish your shopping!
learning: watch a plumber or carpenter or surgeon as they perform their work and learn from it
video games: watch the game as it unfolds to the gamer whose eyes you are renting
if ‘Rent Eyes’ idea becomes feasible then the next logical question is – what kind of business models might be possible? Obviously business models depend on kinds of applications plausible once “Rent Eyes’ beomes feasible. For example in a tourism applicaiton, renter may have to pay a travel guide who is renting his eyes. The tour guides for example could making a living by renting his/her eyes daily for $5/hour. With 10 customers simultaneously renting his eyes the tour guide could make $50/hour touring times square for example. Yet another example. A front row seat at a sports game may cost $1000s but if the person can rent his eyes at $20/rent and finds 50 renters then may be he can watch it for free. Obvioulsy the renter may have reviews and ratings to help users pick the best Eyes!
How to realize Renting Eyes?
Renter wears some form of wearable cameras. The other person watches the feed as the wearer moves around. For examples head mounted cameras made by Gopro.com. Though Gopro gear is complex and meant for recording sports such equipment could be fine for professional tour guides willing to rent their eyes daily at popular places like timesquare, golden gate bridge, Yosemite. Gopro.com. For peer-to-peer use, more simpler wearable cameras would be needed. Such cameras can also help record the visit for personal user compared to conventional handy-cams.
Eye output sharing this requires advances in medical/neuro sciences. The output the eye of the 1st person is captured, digitized and transmitted. This output is then used to feed to the visionary system of the 2nd person (the one paying to and renting eyes of the 1st person). With optical output copying approach the vision limitations of the person may impact the experience. For example if the person renting has visionary impairment such as far sightedness or astigmatism and others then the quality of the experience will be sub optimal. However, this option is too speculative to even dwell further until medical research community can make further advances. More on this later.
Ethical and Privacy Issues
Per SF Chronicle article recently:
laws have been proposed that would require cell phone cameras to include a shutter-like clicking sound, so people are aware when they’ve been photographed.
But mobile phones have had cameras built into them for almost 10+ years now. Privacy issues didn’t surface until now as there is more understanding of the use of the mobile and its impact on privacy.
Parakaya Pravesam – Hindu Mythological concept
In mythological stories of India the concept of entering someone else body is called Parakaya Pravesam. Para means some one other than self, kaya means body and pravesam means entering.
The soul of one of person, typically posessing godly powers, enters the body of another person. Once in there the pWhen soul of 2nd person enters the body (kaya) of someone (para). Once the soul of 2nd person is inside the body of another person then the 2nd person is viewing the world around as well as interacting with the world using his own brain and of course the magical powers as these are mythical and comedy stories.
Scientific advances may never get to a level where they could help experience world of other person in the sense of using the five senses of that person. However, conceptually and theoretically it seems logical. Each of the senses has output (ear, nose, mouth, eyes, skin). If output of these senses feed the brain of the 1st person to produce some output (e.g feeling cold), it is possible that the output of the sensors if fed to brain of a second person could produce same output.
Sensor output capture and replay may be an area for medical and scientific community to explore – how to exract neuro signals and replay them by passing to another brain? If we can then we may be able to play things of past like in a time machine except that we can only play the past and not the future. But may be even future is possible as speculated in the movie ‘Inception’.
It is also possible that somehwere in our body the creator has left a port that emits all data going to brain. Only if we can tap that port and copy the data going to brain then perhaps the data can be fed to another brain/person to help that person see and experience what the 1st person’s brain did. A music recorded on tape plays the same when you put the casettee in a music player whether it is from Sony or from someone else. Likewise, if the senory data going to brain can be tapped , recorded and used to feed to brain of another person, we may be able to achieve partial parakaya pravesam.
This chatper contains five simple sections except the last one.
I would encourage teachers to do open book test on this chapter as kids do need periodic table as well as some material from the chapter that better be used as reference than memorize.
Some of the concepts are too advanced, particularly the mlecular geometry. Could have been avoided or introduced later when needed to explain something else.
- Introduction to Chemical bonds
- Covalent Bonding and Molecular Compounds
- Ionic Bonding and Ionic Compounds
- Metallic Bonding
- Molecular Geometry
Time permitting, I would love to continue the hypothetical atom house story and build on that to introduce formation of compounds and attractions/repulsions in thus formed complex structures.
For now, kids should be able to benefit from just doing this practice worksheet using open book.
Parents and teachers can coach using the questions which are all from HRW book. These are good set of questions to help quickly get most of the concepts from the chapter into their brains if they are strapped for time and can’t read the lengthy and verbose chapter.

Could it be possible for periodic table pattern and rules to be found in genetics and extrasolar systems?
It appears that there are efforts to catalog and tabulate all discovered extrasolar planets so far.
If there is pattern found in the tabulation then it may be easy for scientists to predict yet-to-be discovered planets just like how Mendel predicted existence of three not yet discovered elements back in 1870. All three were eventually discovered during his lifetime.
Some questions to ask for now. These may take long time to find answers if there will be answers. But nonetheless worth hypothesizing.
Could there be some cosmic order on how planets, life, and elements are created?
Could there be sibling planets to earth, sibling planets to Jupiter like sibling elements in periodic table?
Could number 7 be behind the cosmic order like it is behind so many other things including the upper bound on periodicity in Periodic table of elements?
Come back here in 50 to 100 years later?
This idea came up while creating reading aid on Periodic table and how best to teach it to kids. The number of rows in Periodic table is 7. What it means is that there are at most 7 sibling elements that exhibit similar characteristics.
For example there are seven noble gas elements: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They are siblings and exhibit similar characteristics. From electron configuration of one element one can formulate electron configuration for the other sibling elements. Further, from existence of one element we can predict existence of its siblings even if they are not yet discovered. That is what Mendeleev, the creator of Periodic Table did. He knew some elements but not their sibling elements because they were not yet discovered. He left spaces for them in his table and three of them, gallium, scandium, and germanium, were found during his life time.
There is also a myth in India about there being potentially 7 copies of each person.
Could biologists, working on Human Genome database, explore this question: are there at most seven siblings of any particular gene? Knowing one, can we construct the sibling genes?
Could there be Periodic Table of Human Genes if the higher order (the God!) used same rules for life building blocks ( cells and their genes) as he did for non-life building blocks (elements and their atoms)?
Could rules around arrangement of electrons inside atoms and periodicity of elements be same for configurations of amino acids in genes and periodicity across genes?
Will biologists be able to discover new genes based on periodic law for siblings?
There are seven types of anxiety, so the scientific community claims. Could the number seven be related to the column height in periodic table or the group number (I,II, III,… VII)? Or could there be more types of anxiety if scientific community takes clues from d-group of periodic table?
Some topics interesting to write or read about :
Vyas : is he the most prolific fiction writer of all times?
Vyas is credited with creating Mahaabhaarat, the great Indian Epic. He used several concepts in his fictional works. One concept used in the story of Jaraasanda can be seen in Matrix. Air transport and war equipment concepts can be seen in modern-day warfare and space exploration – Helicopters, Cluster bombs, drones, Space shuttle and so on.
He created a complex story with hundreds of characters and side stories without getting lost. The story is several thousand pages, packed with numerous bed time stories, entertainment, and serious philosophical concepts and diatribes.
It is written using Sanskrit, a language used only for writing and one that is not spoken! That is why it is called vikruti (un-natural) language. The prakruti (natural) languages of India are ones such as Hindi, Marathi, Telugu, Bhojpuri and many others. In ancient India Sanskrit was used merely for inter group communication in writing while each group used their own local language. A Sanskrit scholar would translate and read out, in local language, messages from distant kings or pundits. Today the place of Sanskrit is taken over by English.
Only Rowling could rival him in terms of volume of output. But then she had access to lot more previous works to get inspiration and synthesize and more importantly access to writer tools – typewriter and computers. Vyas didn’t have such luxury. He supposed to have lived on an island near Yamuna River in current day Uttarpradesh province. An island area that one can only be reached by swimming or by boat. Several things worth talking about Vyas and his main work – Mahaabhaarat purely from creativity of individual human spirit.

Second Law of Thermo Dynamics – one that means so much without saying so much
is there some message in this simple physical law so well articulated by scientists?
Does the concept of over governance defy this law?
What about young theologies that enforces order and civil behaviour against this simple physical law? Aren’t they up against the natural law?
Does this law foretell what the world might be in few thousand years from now ?
Will there be country borders and governments in future?
Some one associated with Ayn Rand institute, recently opined that western civilization is on decline and that some of the government policies are setup against the spirit of free markets. Is that expected anyway from the 2nd law?
Did Karl Marx knew of the 2nd law? How did he think social economic order can be enforced against the will of nature as the 2nd law states.
Too many questions but very few answers. Could be worth multiple PhDs in social and economic sciences?
A great mind and thinker of 20th century. For many of us she is the most recent classic author that we know and can relate to. She uses unique and time-tested style to get her message and philosophies across. There is not many that come to our mind in terms of using story style to get powerful philosophical views across. May be Chānakya (c. 370–283 BCE) from Ancient India used similar approach? Or could it Vyas, the ancient India scholar credited with creating the most complex story called Mahaabharat about 5000 years ago ?
History of Telugu Language : does it need correcting?
Is Telugu, a language considered Italian of the East for its suitability for singing, littered with pseudo Telugu literature from the likes of Nannaya , Tikkana, Errapragada,Viswanatha Satyanaryana and others ? Did they use Telugu script to merely transcribe poems and literature from equivalent Sanskrit works? How much of their works is original and written in achha Telugu? Should Telugu language history reclassify Nannaya, Potana, Viswanatha Satyanaryana and many others as great Sanskrit scholars and provide rightful appreciation and credit for those who actually contributed original compositions in acha Telugu?
Thyagaraja, Annamacharya, Chalam, Gantasaala, Srinatha, Sri Sri, Kandukuri Veeresalingam, Atreya, Arudra, C . Narayana Reddy and others contributed lot more to Telugu using local character, cultures and spoken words than the Sanskrit copiers. Did other authors, and in particular ones from Telangana., contribute more to acha Telugu literature than the traditional Sanskrit scholars that lived in AP in the 12-18 centuries? Are these old sanskrit pandits Aryan descrents of north who happened to live in AP?
Should Telugu historians, besides removing linkage with Nannayya and other Sanskrit copiers, even remove some Telugu letters / suffixes created by the pseudo Telugu scholars as part of their transliteration of Sanskrit work?
Gita: manas, budhi, atma
In Mahabharat, in the final battle between the two clans a warrior of one side refuse to fight fearing blood shed and family destruction as both sides of the armies are of his own race and blood. In here, Krishna, the charioteer to the unwilling warrior, has some words of wisdom to the warrior.
Vyas creates this fictional scene to present his metaphysical concepts. The whole dialogue between the frail fighter (the passenger) and the charioteer is the most complex in terms of metaphysical concepts and speaks for the creative genius of Vyas.
Though Socrates, Nietzsche and others may have had their philosophical excellences, what Vyas produced in Gita is unquestionably the most challenging piece of work for any linguist or philosopher. One particular dialogue that is fascinating to read is the one where the charioteer tells the unwilling fighter the relation between self, body, soul, intellect , desires, and worldly objects – too many metaphysical concepts that are difficult to understand without an analogy. Here is the analogy that is so wonderfully constructed:
Self is the passenger of the chariot; body is the chariot; soul is the charioteer; mind is the rein; organs (or impulses or desires) are the horses; external world of objects that we desire to seek /explore are the roads.
Atma is the passenger of the chariot; Sharira is the chariot; Buddhi is the charioteer; Manas is the rein; Indriyas (or in Telugu Korikalu) are the horses; external world of objects the roads.

Thank You China Day
Thanks Giving, Labor Day, Mothers day, Fathers Day, Veterans Day, Presidents Day – all of these for good reason.
Folks in China deserve appreciation too for many things they produce from iPhone to hospital supplies for families all over the world.
So why not all countries declare ”Thank you China Day’?
