Happy

I am happy that I finally got my ticket to India. This is special because none of my travel agents could get tickets and the only one to get cheated me on the itinerary. Its a market in itself and I was taken for a fool just like an investment bank would have but instead it was a travel agency.

Instead, I found a ticket for myself using my own methods, close to my budget ( this is the most expensive ticket I have ever paid to India) and on my own terms. I am excited either way because I am looking forward eagerly to it.

On another front I am happy to hear the words "Lets Party!"

Thanksgiving and all that horror!

Come to think of Thanksgiving as a holiday, it is virtually unknown outside of US. Originally founded as a way to thank god and the Indians for giving the land, now it retains a scope far bigger than it was et to be. And after 7 years of my stay, I was finally invited to a true turkey and ham lunch. The week before was quite rocky with a customer handing over my ass to me in my hands, a good relaxation session with folks in the east coast followed up by a friendly reunion with my old employer. The last week was even outrageous considering I picked up a fight in the bar and drank myself to glory. Co-workers tell me my cuss word frequency has increased and that I was displaying aggression uncharacteristic of me.

All in all, it took me an year to my current stint to earn a respect as a "man" enough in the firm that I am now on the invite list to 2 of the celebrated parties in the bay area. Previously, I was a supposed to be a geek (literal definition a carnival performer who does disgusting acts) whose job was to turn shit into something sellable and once you had enough produce turned into gold, I presume you naturally get invited. My thanksgiving lunch was supposed to be a warm-up for the upcoming christmas and other parties.

Where do I start? The even kickstarted at 2:00 pm when my gracious host enquired about my poison of choice to which I responded Beer. We then deep fried a duck (in a nice stainless steel canister fueled by a propane gas tank) while we waited for other guests to arrive. One was a wealthy old man who changed his houses more often than his cars. Then a lady in VW Eos appeared. As a conversation starter I enquired as to where she worked, to which, promptly came the response that she was laid off. Err.Umm. She also bought a condo and this new car just 15 days before. I moved on to other topics.

Later, we were followed by a true blue American couple, call then D and T. Now T was an admirable personality who always complimented his wife D and seemed like the party was on its way to start. The view from my hosts' deck was fabulous with Mountains (and Mountain Lions, I was to discover) and the city traffic flowing like blood corpuscles to and fro. Overall, it was a nice view to soak yourself into with a Martini (which is what I promptly did).

We were ushered into this dining room shortly where the lunch was supposed to commence and I was struck by the formality of the process. Silverware and table laid out for a 4 course meal. The background was a huge painting of Eiffel Tower with photographs at its different phases of construction. The other end was a transparent view of the hillocks and the lake nearby. Absolutely perfect to be lunching in such a nice ambient "french-looking" room. We sliced our ham and ate our turkey with rejoice. Finished the meal with a nice cognac and some cigars in the lounge. Now, comes the dreadful talk of civilized men. Well, after such a hearty lunch its easy to forgive most things in the world and probably T knew this because he brought up the distasteful subject of politics . We politely nullified him by hijacking the subject to that of Wines and opening the cork of a 1995 Silver Oak Cab. Very nice I must say. The wining and chatting continued and more progressively the subjects grew distasteful.

By 8:00 pm I knew the precise psychological moment when I should be hitting the hay and lied down on the couch without much ado. I woke up around 9:40 pm when I heard a strange sound thats was polluting the nice background streaming music being rendered out of an iPod. I saw this VW Eos woman sobbing right next to my couch. Instead of asking whats wrong, I asked her if she cared for smoke. She said yea and we headed to the deck to get our nicotine fixed. Then she started sobbing more and I pointed this would dilute the nicotine fix. I wanted to know her sob story in exactly one sentence. She said she broke up this Monday, lost a job on Tuesday and has bills to pay. Phew! Straight out of a horror movie. Also seemed to have a insecurities regarding her age as she tried cover it up by saying "there is no such thing as too old" to which I retorted, "No, There is.." The the conversation went something like this

She: Shut Up. You are the youngest one here and its better you keep
quiet
Me: Okay.
She: Smoking is very bad for your health.
Me: Uh Oh!
S: My mother died of lung cancer even without smoking
M: Too bad, Just as one prefers to be loved and lost than to be lost
forever, so I would prefer to be smoking and then getting a cancer rather simply
contract the wretched disease

[she stubs out the cigarette as she isnt in a morally superior position
lecturing about the ill while doing the same herself]

S: I stubbed it so that I can resume my anti-smoking spiel.
M: Pray Continue (while I finish my stub..)
S: Its disgusting that you choose to smoke first thing after you wake
up
M: Your pont being..
S: [Blah Blah..Yadda Yadda]
M: Okay, if I were to do this waking up routing differently what should be
a normal person be sayin to you after he wakes up?
S: For one, have sex with me
M: [Ogling for the lack of better expression]
S: Then the second best thing would be to have coffee
M: Ok. I saw a fine Italian made espresso machine thats glinting by the side of
the kitchen. Let me make you some while I make one for myself.

So the caffeine fixed one awkward part of this party and I joined the mainstream audience at the same dinner table. People were more visibly agitated, drunk and were quite having fun. In a party there are never good or bad people, simply charming or boring folks. I steered my way to my appointed place and started sipping my steaming coffee. Remember the american couple T and D, of which the woman D started speaking about mountain lions and boars in the area. Her hubbie T narrates an incident when they were swimming naked and a wild boar was in the way to their home from the shore. I steered clear of comments (trust me, I know these moments where one needs to be silent) and chatted heartily with the old fella about things indian (like the taj mahal, lack of white lane markers on the road and other standard issue things) . D stares at me and starts the following conversation

D: So you are from India
Me: Proudly So.
D: I like your accent
Me: Thanks
D: How long is your [beep]

I was stultified at this question being asked across a dinner table in the presence of her drunk husband along with other inebriated folks who were trying to do their best to reduce the number of bottles in the cellar. Luckily, my host understood my aggravated situation and mediated to change the subject to more palatable topics. But then, he underestimated the persistence of this woman. She claimed curiosity to be the driving factor at which point I wanted to tell her that for normally distributed population these are the confidence intervals for this mean but that would be too much.

Later, after another round quick turkey burgers to fill up our tummies, D decided to launch the second attack on a different front this time.

D: Are you a virgin?
M:
D: Great! I respect your for that and Trust me its gonna be a lot of
fun
M: Duh! Err! Umm! TaaDaa!

Now D's husband takes an active interest in the future direction this talk should bear and makes this comment that he was playing with GI Joes when D was getting bored and decided to do something for fun. Then, I decided was the right time to call it a day. Thanked my host for having me and treating to some of the best wines. I drove off, thinking about a lot many things with the way these guys defined their lives. There used to be something that the jewish called "covenant" between folks that guided them to do some decent things be it in their marriage,co-worker or friend. Its very easy to break one and I see that guys who break one can easily break another whereas guys who keep one tend to keep most of theirs. Happy Thanksgiving!

Fame's Penny-Trumpet

Blow, blow your trumpets till they crack,
Ye little men of little souls!
And bid them huddle at your back -
Gold-sucking leeches, shoals on shoals!

Fill all the air with hungry wails -
"Reward us, ere we think or write!
Without your Gold mere Knowledge fails
To sate the swinish appetite!"

And, where great Plato paced serene,
Or Newton paused with wistful eye,
Rush to the chace with hoofs unclean
And Babel-clamour of the sty

Be yours the pay: be theirs the praise:
We will not rob them of their due,
Nor vex the ghosts of other days
By naming them along with you.

They sought and found undying fame:
They toiled not for reward nor thanks:
Their cheeks are hot with honest shame
For you, the modern mountebanks!

Who preach of Justice - plead with tears
That Love and Mercy should abound -
While marking with complacent ears
The moaning of some tortured hound:

Who prate of Wisdom - nay, forbear,
Lest Wisdom turn on you in wrath,
Trampling, with heel that will not spare,
The vermin that beset her path!

Go, throng each other's drawing-rooms,
Ye idols of a petty clique:
Strut your brief hour in borrowed plumes,
And make your penny-trumpets squeak.

Deck your dull talk with pilfered shreds
Of learning from a nobler time,
And oil each other's little heads
With mutual Flattery's golden slime:

And when the topmost height ye gain,
And stand in Glory's ether clear,
And grasp the prize of all your pain -
So many hundred pounds a year -

Then let Fame's banner be unfurled!
Sing Paeans for a victory won!
Ye tapers, that would light the world,
And cast a shadow on the Sun -

Who still shall pour His rays sublime,
One crystal flood, from East to West,
When YE have burned your little time
And feebly flickered into rest!

-Lewis Carroll

The Recruit

I have been on a hunt to recruit the best fella I can find for my team. I have been on the other side of the fence but never realized that hiring someone was such a hard thing. Its hard because its not simply like selling a product or asking to team up with us, its hard because I am asking some individual to bet some of his life years in my organization. Scary type of an evangelism if you are a like me where you have your own doubts.Finally I hired a person who started today.

I always had a philosophy that if you recruit someone who isnt a fit its always a mistake of the folks who employs the person, not the person himself. This was the first recruitment I have done in my career and it took me 6 months to find this new candidate. The upside was for the first time I got a thumbs up from all 9 people I had him interview with.

Its interesting that this fellow has his bachelors' in environmental affairs but yet I voted him to know enough abour internet performance analytics given. I am betting on "diamond in the rough" philo here but then bets can go either way and the blame would be on me. My pipeline was almost empty for weeks and the qualifications I was looking for were rare enough that not enough people were in the pipeline to be interviewed and the right ones were already working. If I have such a hard time hiring in the valley, I wonder how folks back in India are hiring in droves while maintaining some semblance of quality/relevance.

Mostly the recruiters dont have a clue and try to make their number by sending in unwashed masses.Once ina while you get lucky and get a good one. I usually dont look too deep into resumes or ask them trivia questions like syntax or features based on a version. Similarly I dont like companies that ask them because it tells me about their standards.I usually ask my prospects to describe whats cool, why things work they way they are now, how they envision the future and finally the limitations of the well known tools (if you dont know the limitations of a popular tool you havent worked extensively enough). I am looking for signs of acuity, insight and understanding.Then I look for qualities like passion and integrity. Passion is neccesary because majority of folks at companies other than startups dont care about their work and it shows on the product (if you dont believe me take the counter example of Apple) plus it is easy to motivate people with passion. Integrity is important because your investment in the candidate would be well worth it apart from it being an infectious quality of making things right.

This exerscise tells me that I have to be on the lookout for the top talent all the time and not neccesarily when I have a vacancy because they are not neccesarily in the market when I want them, so I have to be hiring them when they want to move. In fact, I was literally begging a UC Berkeley grad working for another monster company to join us.

My final objective with this person is that I can take a long vacation and no one in my firm should remember my name in any context when I am on my vacation. We shall see if that happens for this christmas...

Happy Halloween!

Its Nice day to segue slowly onto the holiday season.This is one holiday of the western calendar I love the most. Halloween. Obviously I wondered if the word "hallow" has any connections. It definitely does. Name the day after halloween when the heathen (who might have been scared to death the day before due to some random thing) were en masse allowed into the church? It used to be called Hallowmas (yeah! much like xmas) but officially called as "All Saints Day". I like these "eve" (fun) followed by serious things (mas). Mardi Gras marks the celebration followed by Ash Wednesday kinds, you get it na. I shall go carve turnips.

Searching for Scale

Notes to self:

Are there applications for the Mohring Effect at the packet levels of web applications? eBay made money on this model and created a monster market. I see a nice billion dollar market, increasing demand but increasing COGS as well.How do I drive down price at a constant COGS level with additional services added and hence able to serve more? How?Apparently I never graduated from school since I dont know the solution.

The Mood of the Week

A Few Small Repairs

Sunny left a message today. Said "Hi":) After a hiatus of 3 years it felt nice to be remembered by an old acquaintance. T,myself and sunny went to the same grad school back home and now they are married with a kid.Gosh! For me out of sight really means out of mind. That single message trickled an avalanche of old souvenirs in the memory lane. How hard it was to persuade T to take the first steps, the holi where I told him to see life in red hue, and the later turmoil after I left them and as they say "All's Well That Ends Well!"

Coincidentally I was playing a song recently whose lyrics I used as an inspiration for T in a contorted sense to "patofy" her.

Like a delicate sound in the backdrop of thunder
look at you standing still amidst the lightning flares
melting in the indian sun
casting a shadow in moonlight

like a tune out of someone's veena in the street

imagination in front of desire's doodles..
a light ray that would never reach its source

Damn Funny Lyrics to translate plus it made a whole lotta sense then.Now, I feel like Rajat Kapoor narrating a story a la "suraj ka saatwan ghoda"

Another Day Of Getting Older..

Lucky Ali's in his album "Aks" start off with a croony : "Yeh, sawera chale, jaise milne aa gaye mujhse sab dost mere ." Occasionally I wondered how would I react if such a thing happened. I came close to it when most of my friends either called up or wrote emails on this particular day. The last known such constellation of "dosts" was for my graduation when we had a rocking time after which slowly one after another returned home to India. The official count of people who didnt return in my orbital is 2 (including myself). We all could trade a little growth for happiness is the lesson that I learnt from them.

Dad took me by surprise when he found an old manuscript where I was taking some survey notes on Casimir Effect. It was a nice gesture from him taking the time to exactly reproduce it (including my typos/spelling mistakes). Since he sent it to me electronically I wanna store it somewhere like this blog. Its a lot of work considering all those subscript/superscript/greek symbol stuff.Here it is

Most people think vacuum is place where there is absolutely no matter, a place that contains absolutely nothing. However such a thing is impossible. So a vacuum is actually where there is very little matter . A good vcuum means almost lack of air, dust and other samples of matter. Note the keyword here almost. But one theory which caught up in 1970s was the Universe can be considered as a vacuum fluctuation. It states that the Universe and everything in it may be no more or no less than than one of those vacum fluctuation that allow collections of particles to burt forth out of nothing fo a while and then be reabsorbed into the vacuum. This idea closely comes on the heels of the idea that the Universe may be a closed system. A Universe that is born in the fireball of Big Bang,expands for a time and that contracts back into fireball and disappear is a vcuum fluctuation on a grand scale.

We know that the gravitaional energy of the Universe must be negative (i.e becase it is bound). So this negative gravitational energy must precisely cancel out the positive mass energy of all matter in it.(E=Mc²)). Hence a closed Universe has a Zero energy overall. This idea can be traced out to 19th century Physicist Ludwig Boltzmann,one of the founders of statistical mechanics. He guessed that the Universe ought to be Thermodynamical Equilibrium,(which it is not when created.) So its present form is temporary stage on the way to reach it which is allowed by statistical rules provided that ht e equilibrium is maintained on average in the long run. In 1971 Edward Tryon of city Univarsity of New York submitted a paper in Nature (vol.246,P396,1973)where he developed an Idea that Big Bang as a vacuum fluctuation,but he pointed out there the time allowed for its existance in line with delta(e) delta(t) = h/2*pi can be a very long time indeed.This concept finally led to baby universes "inflation"& concepts such as these. from "70s we re used to this idea. But this notion is not based on any definite model of what a quntized field system is and hence the present approach which is based on Hamilton-Jacobi formalism leads to very different picture. V.field: In this formalism the vacuum is a non co-variant concept.i.e It will be observed that the field is static.(i.e. this is valid only in a preferred Lorenz frame.)But no experiment abiding by the quantum theory can find a frame in which vacuum field appears static. Though unobservable,the concept of vacuum is helpful in understanding the physics of Quantum field theory. It is similar to the ether concept in physics in which Einistien pointed out that ether is compatible with special relativity if we deprive it of any mechanical qualities.When quantum mechanics is applied to a radiation field by Born,Heisenberg&Jordan the out come was

e(ns) =(ns + ½)h עs

where ns=0,1,2 gives the spectrum of energy level.

Increase of ns corresponds to emmission(or creation) of photons while decrease represents vice versa Thus the state of the radiation field can thus be specified by writing down in an ordered sequennce the number of photons present corresponding to the various frequncies.This is the "occupation number". The word 'vacuum' is a misnomer in this context since space is filled with a field which carrys energy. Now even "Grand space" is not proper as since we will see later that by a change of boundry conditions in reg.egns we can attain a state of lower energy. So even for an occupation number "Zero' the field does have a Zero point energy as given by the

∑ ' (½)hעs.

A field is a useful concept used to describe particles. The moment we talk about a field, we must be able to specify its amplitude as a function of space and time. The Amplitude could refer to a scalar field,vectorfield or spinor field. At this point we must note that thehre are two types vacuum one has to deal with:

vacuum associated with electron field

vacuum associaated with electromagnetic radiation.

In case of the electron field we deal with a spinor field ψ (sanpace,time) and in case of EM file we deal with vector field amplitude A(Spae,time).But having a field amplitude Ψ does not suffice to deal with a many paarticle system as Dirac used it to only for one electron system.To customise it for many elctron environment one must first declare Ψ as an operator and then specify its anti communator ψ (r',t').

Vaccum associated with EM field : The quantum theory as noted earlier does not
consider vaacuum s a state of emptiness.In this formalisation the vacuum state of electromagnetic field. corrresponds to all the radiation oscillators being in their quiscent state. Their occupation number is Zero and are called Zeropoint oscillator We can consider the vacuum state of field by ψ 0 us. Now on a practical level, one creates or annihilates photons in a paraticular state,say k. For this purpose one defines the annihilation operators a+k ak in terms of A. Similarly we define creation and annihilation operatoars b+k, bk in terms of ψ In this Hamilton -Jacobi formalism, an asumption of classical field is made.The assumption is that " At each instant 't' in a field has a well-defined value for all X Whatever be the state of the field.".Hence in this formalism made creation & annihilation operators araae respectively given by
ak+ = (2k)-½ (kq*k - δ/δqk )

ak- = (2k)-½ (kqk - δ/δqk* )

where k = ‌│k│ and satisfy the commonation relations:

[ ak, ak '] = ( ak+ , ak"+ )=0; (ak, ak+ ) =δkk'

In some literature the factor of K is on the right hand side where as in some it has a factor of k-1 on the left hand side. The vacuum state of the field ψ 0 is the stationary state defined by the requirement ak ψ 0 =0 for each K. where ak is the annihilation
operator.Using 1,above, we have:((kq*k+ δ/δqk* ) ψ0 = 0 for each K

or equivalency[ (─‌‌‌►2 ½ ψ (x) +δ/δ(x)] ψ 0=0 for each x

where (─‌‌‌►2 ½ ψ = v - ½ Σ ',kqk e'k .x is the limit of continuous K.

Solution of these differntial equations yields usψ 0 (q,q*,t) =N.Π k/2 e-k q k* q k ─i
or can be simplified asψ 0 (q,q*,t) =N e- ½ ∫ ψ (x) (─‌‌‌►2 )½ ψ. ψ (x).δ3x─1 Єot ---6 where the normalisation constant isN = .Π k/2 (k/Π) ½Now in these coordinates the Schroedinger's equation becomes:i ∂ψ/∂t =∑,' [ ─∂²/∂ q k ∂ k* +k2 ∂ k* q k )------------------------7 k/2 Now the energy could be found directly by direct substitution in to 7 above. to be asЄ0 = ∑,' k/2clearly this is infinte.Confirmation:The equation 5 above is a product of the modes, it is the ground state of an infinite set of independent operators.As we know that the oscillator is at rest,to confirm this,we note to a constant the phase of the wave function given by S= Є0 t.Thus the time evolution obtained as a solution of a guidance formula in Hamilton -Jaacobi formulation.

∂ψ(x,t)/\ ∂t =δ S[(ψ (x),t]/δ ψ (x)

ψ (x)= [(ψ (x),t]/ will become ∂ψ/ ∂t= δ S/δψ=0 or

ψ (x,t) = ψ (x) and hence the field is static. Thus the "Zeropoint" energy,─

δ S/ ∂t =0. This Є0 resides in a quantum +class.por.energy

Vacuum Associated with an Electron field : In the dirac theory all the -ve energy states are filled leading to the so-callead Dirac Sea. Now suppose that tahe elctron has an electrostatic energy Є defined by a function of the distance 'r'. i.e ε(r). If we now consisder a cell of unit volume at a distance r the energy content of the cell is ⅛Π ε² (r). (it is proved before). Hence the total Electrostatic energy is given by

E= ⅛Π ∫ε²(r).dv.

Now if we consider point charges i.e radius of the electron → 0 then E→∞ ;

if a=0 then Є=∞

But as the celebrated scientist Mr.Richard.P.Feynman said that the infinite energy may be annoying,but what really matters is whether there are any observable physical effects. If the changes on energy are Infinite then we are in trouble.
