If my observation is coloured by my experiences, then have I ever seen the truth? Can I ever be objective enough to see the truth, because unless I see the universe as it is, how am I supposed to do anything about it? Will I ever be able to see the truth? And is there a singular reality? Is there anything called 'the absolute truth'? Is not the reality that you see is as real as the one that I observe?
I was watching a video which resonated with the ideas expressed in Hindu Mysticism and the profound science of yoga and personal evolution and I tended to like it because of this resonance. Is not this itself a bias? Irrespective of how great and profound this science is, was not my experience coloured because I happened to take birth in a Hindu family, where I got this kind of conditioning, and external environment that I passed through subsequently? Or did I have it all planned and I will-fully took birth in such environment; because it suited my evolutionary needs so I chose the set of circumstances. How am I supposed to know this without doubt?
The mystics say that one has to understand one's experiences, and resolve the unresolved reactions/fruits of our actions to see the objective truth. It is as if things always existed for you to see, but you had turned too insensitive, too busy to observe. Reaching this state, they say, is the first step to be able to see and program the quantum space - the sub-nuclear, the "suxam" (in Sanskrit) realm.

David Foster Wallace on Life and Work
Those of you who like thinking about 'what and how to think' and how to get into a conscious habit of doing it will enjoy reading this article.
Though Mr David talks about only the emotional, moral and human aspects of 'thinking' here and not necessarily about problem solving and more action-oriented applications of this 'art', nonetheless it is worth reading and pondering over.

Save me from folly, vanity and vice !
I was reading Benjamin Franklin's autobiography. It is amazing to see how the man rose from a life of obscurity (born as a son of a candle maker) to one with great accomplishments and influence of epic proportions in so many diverse fields. An experimentalist, a theoretician, an inventor, a scientist,a pulisher, a philosopher, a politician, a revolutionary. Though I am still into the first half of the book, but it is an amazing read. The way Franklin distances himself from his life and describes it is brilliant. Even more brilliant is the wisdom that is interwoven throughout. Among other things , it shows one how to see oneself in a proverbial mirror to have a unbiased view and how to succesfully work your way towards what you want to be. A story of determination, tragedies, heroism and ulimately victory. No doubt, he would have been great in any age, any time. It reinforces my belief that some truths are eternal and some laws will always operate in the universe beyond relativity.
I also like the little prayers that he wrote down for himself. Especially the one --
"O powerful Goodness! bountiful Father! merciful Guide! increase in me that wisdom which discovers my truest interest. strengthen my resolutions to perform what that wisdom dictates. Accept my kind offices to thy other children as the only return in my power for thy continual favors to me."
The lines taken from Thomson's poems are also beautiful and elevating --
"Father of light and life, thou Good Supreme!
O teach me what is good; teach me Thyself!
Save me from folly, vanity, and vice,
From every low pursuit; and fill my soul
With knowledge, conscious peace, and virtue pure;
Sacred, substantial, never-fading bliss!"

Quantum entanglement & the dicey game
"Two entities can stay in instantaneous and sponatanous contact, even if they are largely separated in space and time.And an event with one affects the physical reality of the other in the same way even if they are light years away". Doesn't that sound like a very mystical statement.But what if you were to be told that there is scientific evidence for it (as my bretheren who are primarily driven by intellect love to call it)? This phenomenon is popularly known as Quantum Entanglement in the science community, who is in love or hate (we 'll come to it later) with quantum mechanics.
I studied quantum mechanics in school and college, but I knew it only in its present form, never got into or got the chance and time to get into much of its history.Recently happened to do that and reflect upon that.
In 1981, when a certain french youngman Mr Aspect decided, he wanted to perform experiments, which may prove Einstein wrong, it was met with questioning and ridiculing looks.A certain professor said in a very dark tone, "You are a very courageous graduate student,I have met".Before proceeding, let 's look back into the history.In very simple (layman) terms quantum theory says, "It is not possible to predict the state of a particle with certainty before the measurement is made." The measurement or observation is supposed to give it some kind of jolt and it collapses into a certain state.As the famous Heisenberg uncertainty principle said there 'll always be some uncertainty in the state measuremnt on which he put a lower limit, with his inequality.
Mr Einstein (one of the haters of the theory) was always uncomfortable with the uncertainty thing in quantum theory.He argued, the fact that quantum theory can't predict the outcome of a measurement didn't mean, there is inherent uncertainty in universe, it only meant that the theory was incomplete & there were extra variables. As he once famously said, "God does not play dice with the world." So , the physicist who believed in God, devised a thought experiment with two others, known as the EPR paradox (Einstein, Podolsky, Rosen) to dissaprove the theory.Consider a photon splits into two parts and they travel in opposite direction.Now a observation is made on the one particle, which defines its state.Now with newton laws, the state of the other can be ascertained without making any measurement, which contradicts the Quantum Theory(QT). There was a loophole though. What if the first particale signalled to the other, that a measurement is made? To which Einstein had another solid argument, that it can't happen for according to special theory of relativity, information can't travel faster than light.Since there was not much evidence in 1935, none of the parties could completely knock out the other.
Mr John Bell, (in 1960's) showed that for particles to obey these assumptions they should satisfy certain requirement known as Bell's inequality.
Mr Aspect, the french physicist, conducted the experiments suggested by EPR paradox and showed that the results violated Bell's inequalities, and the other photon came to know of the observation (event) on the first (it knew more than it was supposed to know), proving that quantum theory was valid, which was badly shaken after the EPR paradox.
So, that meant either one or both of the assumptions made by EPR were wrong.The certainty thing or the info can't travel faster than light one.But it was argued later that the inequality violation didn't necessarliy prove that info can be sent faster than light, & the other assumption was also saved referring to some loopholes in the experiment.
Well, all this has very interesting implications. In a way, it violates the concept of local realism i.e. the state of a system is not only decided by its interactions with its immediate surroundings but also by other particles it is entangled with.What if you had a soulmate, that you are entangled with , on this planet going through various circumstances; interesting??? Or even fancier and not a weak possibility, in some other part of the universe?
Another implication can be the mystical notion that all the particles of the universe are instantaneously interconnected and can exchange information. Telepathy can be a possibility.
A few more aplications are quanatum computing( which can be dramatically faster than the existing one) and teleportation.In fact, some quantum teleportation experiments on quantum particles are already performed.
And the very interesting one, "Does God play dice with the world?" I don't have any answer. Truth is very slippery & elusive. Just when you think, you have got hold it, it 'll slip out.On a very quasi-objectve basis, I feel, sometime he does, sometimes doesn't.
Einstein, till his last days was trying to find one unifying theory, that doesn't violate relativity and doesn't imply 'God playing dice'. His befuddlement is really understandable.So, is there a theory that can explain all the mystical, intellectual, quantum & classical phenomena and off course the dice game?

Wirelessly yours ...
So,the issue is the current turmoil or change or consolidation going on in the wireless chips industry.As you are aware of the tremendous growth that is going on in the wireless communication area in developing countries, and the potential remains largely untapped.For example,India ,currently, with only 185 million mobile connections in total,and adding somewhere 5 million connections per month and with only 2% access to mobiles in rural areas, provides a mind boggling opportunity.No doubt the penetration will increase with affordabilty of handsets and the tariff rates.
So,Let 's look at what has been happening around.
We are living in interesting times. The semiconductor industry is getting increasingly competitive. The wireless domain is seeing a lot of activity as seen in this quarter.
Nokia and ST microelectronics went into a agreement regarding the licensing and supply of integrated circuit designs and modem technologies for 3G and its evolution.
As facilateted by this multifaceted deal, (a) Nokia will license its 3G technology to STM.(Nokia has plans to license it to other players as well).This 'll enable STMicroelectronics to design and manufacture 3G chipsets based on Nokia's modem, energy management and RF (radio frequency) technology and deliver complete solutions to Nokia and the open market. (b)Nokia will be transfering its IC operations to STM which will concern nearly 200 Nokia employees in Finland and the UK, and is expected to take place during the fourth quarter 2007.Basically, Nokia will completely come out of the chip making business to focus more on its core competencies.
Nokia will continue to develop its modem technology, which includes protocol software and related digital design for WCDMA/GSM and its evolution. This modem technology will then be licensed to chipset manufacturers who will develop and produce chipsets for Nokia & also for the open market.
Nokia has increasingly sought to widen their chip supplier base as part of their business strategy (makes sense) & will have more than one supplier for all key parts of its phones.
It unveiled plans to develop Broadcom as a supplier of EDGE (Enhanced Data rates for GSM Evolution ) chips. This is a 2.5G standard. While Infineon will supply chips for GSM domain ,as announced early in this year.
Until now, Nokia has mainly relied on its own chips and on Texas Instruments.TI continues to be the only supplier across all wireless standards.With these developments Nokia aims to lower its R&D expenses.And TI will go up against increased competition but TI's wireless revenue from Nokia can still continue to grow as Nokia’s market share is stable to increasing, though the monopoly that TI had on Nokia's business is not there now.As I said, It makes business sense for anybody to have more than one supplier.
This multi vendor strategy in industry has also created a lot of new business opportunities for different players.
For example, TI has been continuously increasing its collaboration with Motorola and Ericsson, building on its already strong position in wireless business.I see the engagement with Ericsson as more strategic and important, as they are into the business of supplying platforms for wireless products covering a broad spectra of cellphone companies.
Samsung also has extended its agreement with Texas Instruments to use the company's OMAP platforms and Bluetooth technologies in its upcoming handsets. Earlier Samsung's BlackJack & SGH-i620 had made use of TI's OMAP processor.
TI grabbed one more opportunity when Motorola announced its plans to remove Qualcomm from its 3G roadmap in favor of Texas Instruments, come mid-2008. According to a report from American Technology Research, Motorola has already begun to move resources away from Qualcomm 3G technologies into 3G efforts from TI.According to sources, Motorola felt that Qualcomm was getting increasingly difficult to business with.Though it was not made clear whether it was because of financial issues or technical ones.
Also in Japan, TI's business with SEMC, Sharp, Fujitsu and NEC has been gaining good momentum.
And what effect all this will have on Qualcomm? It has been the biggest licenser of handset technology. Till now, only Nokia, Sony-Ericsson and Qualcomm had the talent to make the chipsets for the so-called third generation phones, Nokia’s decision to license its wireless technology broadly will arm lots of new players with the talent to get into this biz. Now that this critical technology will be available to license, the technical hurdles to make 3G chipsets have suddenly become much smaller.This will potentially mount the competition against Qualcomm.
Qualcomm is also facing some big legal battles with Broadcomm. And it was on the losing end when the Bush administration declined to veto a ruling by the International Trade Commission that favors Broadcom in a major patent dispute with Qualcomm.
In another interesting develoment, Infineon has bought LSI Corp's wireless products business for $450 million in cash, plus a performance-based payment of up to $50 million (If the group meets certain targets).About 700 LSI employess will be moving to infineon as a part of this deal.(As a rule of thumb a share of around 10% in wireless chips market is considered good to have healthy profits).Needless to say Infineon needs the scale to compete in the very dynamic & increasingly competitive wireless markets and LSI is looking to focus more on its storage nad networking business.All this looks like some kind of consolidation in the industry.It made sense for Nokia ,too, to loosen the vertical integration ,it has long practiced in the industry.As motorola did 2 years before and Apple is successfully doing by sourcing the various parts from different parties.
As a dessert to the main course, let me serve some rumours that are doing rounds in industry circles, mentioning some Taiwanese company(MediaTech) in talks with Analog Devices regarding the wireless business, looking for some kind of acquisition.But,as I said, these are rumours,as of now, so avoid over-relishing & overeating.
With all this, it is anybody's guess how the market would have responded to all these changes? Even president Bush could have guessed. :-P
