Elusive Particle of the Universe

Hi, welcome to you for the year of light and welcome to you for this interesting lecture.

Celebrating IYL 2015

Yes, we are talking about light, the light which is responsible for the diverse life on Earth and spreads in the unimaginable universe.  In the last lecture we spoke about the first light from the Big Bang called CMBR.  But in this lecture I don’t directly talk about light.  Instead I talk about atoms!!

Atoms are the building blocks of matter.  We have more number of atoms in our eye than the total number of stars in a galaxy.  This is true with any object which is of the size of an eye.  In principle we humans are all collection of atoms that have different names!  The matter which surrounds us is also a collection of atoms.  Suppose if I am drinking water from a glass.  If you shoot this in a video-camera which can only detect atoms regardless of their physical size, shape, and features, you can see that some arrangement of atoms drinking the same atoms which are in different arrangement.  This means that, you can form infinite number of structures by arranging atoms.  That is what the nature is doing from all these billions of billions years and it continuous do it in future also.  So, if you look at animals, birds, plants, humans, mountains, earth, stars and galaxies all these are just arrangement of atoms.

So it is important to study about atom.  Until the beginning of 20th century, scientist thought that atom is an indivisible particle of the universe and the fundamental particle of all the objects.  Later many observations and sensitive measurements by the 20th century scientist proved that atom is divisible.  Today we know that atom is made up of proton, neutron and electrons.  Protons and neutrons make up the nucleus which concentrates most of the atoms mass while the electrons revolve around the nucleus.  If I have to give you the feel of an atom or how big an atom is; imagine like this, consider this room (Auditorium) is of the size of an atom and this tennis ball (author is holding tennis ball) is a nucleus, than the smallest dust grain that you can find in this room is an electron!  This means atom mostly contains an empty space!  All the mass is concentrated in the nucleus.  This is a distinctive sketch of an atom.  But you might ask me a question… Do all atoms show the same characteristics?  The answer is no.  Atom with some fixed number of protons, neutrons and electrons have some physical and chemical characters.  But if you change the number of constituent particles of an atom, the characteristics also changes.  This means that if you change the number of electrons in an atom it exhibit different characteristics than the previous one.  Depending on the number of electrons in an atom a specific name is given to them, like hydrogen which has one electron, helium which has 2 electrons and so on… These are called elements.  These are arranged according to the ascending order of the number of electrons in their atoms.  This is called Periodic Table.  This table makes us to easily identify the element which has a specific character depending on its electron number.  This is about atom, and its constituent particles and their arrangement and how there characteristics changes.  But why am I talking about this, instead of light!

Yes, I will talk about light, but for a while let us go back to 1930.  Wolfgang Pauli an Astrian physicist was trying solve the mysterious violation of law of conservation of energy in process called Beta Decay.  I know all of you know about law of conservation of energy, in simple words the law says, energy can neither be created nor be destroyed.  It can only transfer from one form to another form.  And also the energy of the entire universe is constant.   In a given process the energy before the process and after the process should be equal.  No room for violation of this law in nature.  While doing math’s we may do errors in calculating the energies, but nature do not do any error.  It never violets the law of conservation of energy!  But something strange was happening with beta decay.  To know this let us learn about beta decay.  Since we know about atom, it is very easy to understand this process.  In certain elements the nucleus which contains protons and neutrons becomes unstable due to the more number of neutrons than the protons.  If something is unstable it has to give out or it has to accept something in order to attain stable position.  Here we have only protons and neutrons in the nucleus.  So, what happens to this unstable nucleus?  Yes, an extra neutron in the nucleus decays into proton and in this process an electron is emitted out of the nucleus as shown by the below nuclear reaction. (The elements which shows this behavior is called Radioactive Elements and the process is called Radioactivity). This process is called beta decay.  (Beta particle = Electron).  This is an observable process and the experiments have confirmed this nuclear reaction.  But what is the strangeness about this nuclear reaction?  You might be surprised to hear this; this nuclear reaction is actually violating the law of conservation of energy!  But the question is HOW?

n -> p + e

If you equate the energies in beta decay process, you will see that the total energy of the emitted particle is less than the energy of reactants (for now consider it as reactants).  Let me explain this… In beta decay process an extra neutron in the nucleus decays into proton and stays inside the nucleus.  But an electron ejects out from the nucleus and this electron does not belong to orbital electrons, because it is created in the nucleus and emitted out.  But the amount of energy that electron is taking out from the nucleus is less compared to the energy used in creation of the electron.  This tells us some energy is missing in this process.  When we do the experiment, there is no signature of any other particle taking the missing energy. Then where is the missing energy?  This is the question that haunted many scientists during the twentieth century.  So what do you conclude based on our experiment?  Is nature violating the law of conservation of energy or our calculations are wrong?

Pauli worked extensively on this problem of missing energy in beta decay and finally arrived at one conclusion.  He believed that the universe is governed by the order of natural laws.  And he had firm believes that nature does not violates these laws.  More importantly he also believed that his calculations are correct.  He said nature is not violating law of conservation of energy.  The missing energy in the beta decay is transmitted through a particle called ‘Neutrino’ which has zero mass but has the energy which corresponds to the missing energy!  He wrote down all the mathematical calculation to prove the existence of this particle which he called Neutrino and published the paper.  But many scientists did not believe Pauli and went on claiming that, this kind of particle does not exist.  But Pauli who was theoretical physicist, I mean the one who do only math and calculation to give the theory of nature had solid-believe on his theory.  I should say he trusted his calculations so much that, he always said this particle; I mean the neutrino should exist in our nature.  This is the beauty of understanding the nature.  This is where we should appreciate our language called maths and equations.  The numbers and equations hide the unseen exquisiteness of nature.

n -> p + e + nubar

Finally the beauty of Pauli’s calculation unfolded in the year 1956, when two physicist Frederick Reines and Clyde Cowan announced that they have indeed detected neutrino’s in beta decay process predicted by Pauli.  It nearly took 16 years to find the existence of the particle predicted by the great physicist Pauli.  But you know what, nearly trillions of trillions of trillions neutrinos have passed through your body while listening to this lecture.  For every minute billions of neutrino is passing your body.  The earth is in the shower of neutrinos from the sun, stars and galaxies endlessly.

Today I am here to talk about neutrinos.  When Pauli predicted this particle, he said it has energy but rest mass of the particle is zero, which means these particles never come to rest!!  So, how do we detect this particle?

Sir, I have question.
Go Ahead (Author)
Sir, Why do we need to detect neutrinos?  Should we detect them only to explain beta decay or is there any other use from them?

Very good question.  Beta decay problem is over, it is now confirmed that neutrinos are emitted from the nucleus and law of conservation of energy is successfully explained with this particle.  I will reframe your question like this; why do we need to detect neutrinos on a large scale? Does it give any information to us?  The answer is yes and let me give you one such example.  Let us talk about Sun for a while; the thermonuclear reaction happening at the core is powering sun’s total energy.  During this reaction photon (particles of light), neutrinos and other particles are emitted.  The light that warms the surface of the earth as well as you and me has come from the photosphere of the sun.  Photosphere is the visible disc of the sun.  As we all know that light contains photons.  These photons are generated at the core of the Sun.  It takes billions of years for a photon to reach to the surface of the photosphere; from there the photon takes only 8 minutes to travel to the earth.  So the photon which is warming you right now has left the sun’s interiors billions of years ago.  Yes….. Absolutely amazing right!  If you study this light you will be actually studying the sun’s interior which is present some billions of years ago.  So you cannot study real time sun’s core in the visible light.  But on the other hand the neutrinos which are created at the sun’s core travel to the earth in just 8 minutes.  This is because neutrinos do not interact (very very less interaction) with matter.  They just pass through it.  But photon suffers trillions of collisions with the matter spending billions of years inside the sun before emerging out of the photosphere.  So detecting these solar neutrinos is very helpful in monitoring real time sun’s core.  Not only Sun in all the high energetic explosions (Supernovae and other) that happens in our universe emits neutrinos and detecting them will give us clear picture of these events as well as our universe.

How do we detect them?  As I said neutrinos interaction with matter is very less.  They can pass through humans, buildings and even mountains!!  That is why they are called as most elusive particles of the universe.  But if we detect them we get a lot of information about our universe.  So here it is an astronomical observatory built half a mile down the earth.  This is Super-Kamikonde Neutrino Observatory built under Mt Ikenoyama at Japan.  This is a human eye to watch supernovae in our milky way galaxy.

The observatory is built underneath the mountain.  This is because the instrument which detects the neutrinos is very sensitive.  Apart from neutrinos there are other elementary particles reaching earth.  If we have not shielded our instruments then the detector will pick up the signs of unwanted particles.  How to shield these particles? Yes, go underneath the mountain; let nature itself shield these particles (Most other particles can interact with matter).  Most of the neutrino observatories are built in the abanded mining places.   Since neutrinos don’t interact with matter, they just pass through the mountain and to the detector.  And because of zero interaction with matter for billions of years, they have the information of past!  If you detect them you can actually get oldest of old information regarding our universe.  Detecting even a single neutrino requires lot of big observatories like this and lot of patience because of its elusive nature.

In this observatory, 50000 tones of distilled water are stored and it is surrounded with scintillating tubes which detects the minute flash of light.  But how do you get this flash of light in distilled water?  In a minute trillions of trillions of neutrinos are passing through this huge detector.  Suppose if one neutrino interacts with the nucleus of water molecule, an electron is emitted.  This electron is detected by the very sensitive scintillating tubes by producing a flash of light.  Each flash of light can signifies the presence of neutron in the detector.  If the activity is more in outer space, I mean if there was a supernova in our galaxy, then flash of light increases indicating the presence of more neutrinos.  This has been observed during the Supernovae-1987A in the year 1987.

A flash of light is used to detect one of the most elusive particles of the universe which hides rich information about our home.  It is again the light that is doing our work!

Happy International Year of Light.
Thanks a lot for listening to me, that’s it for today.
Have a great evening.

First Light – CMBR

Celebrating IYL 2015

     If you look at the modern periodic table you will find hundred and eighteen elements listed in it. Out of this, ninety four elements occur naturally.  All these elements can be found on Earth (exceptions are there).  Elements are building block of things that you see around you.  Whether it’s a human, animal, tree, building, roads, bridges, monuments, mountains, etc, everything is made up of elements.  But the question that comes to our mind is who brought all these elements on the Earth?  How are they formed?  The answer is… all these elements are formed inside a star.  Yes, in a sense, everything that you see around is cooked inside a star!  Richard Feynman, a famous physicist once said that, the stuff which we are made was once cooked in a star and spit out.

      The entire universe comprises trillions of trillions stars which cooks the matter that we see around us.  The next question that arises is how do these stars form?  Well, these kinds of questions will go on….. it’s a never ending process. But then, where do we begin?

Yes, we begin at the beginning.
We begin at the Big Bang!

Big Bang
Artist view of Big Bang before the explosion.

     The universe which includes stars, galaxies, nebulae etc. is expanding for billions of years.  If you look back, somewhere in the past there must exist a time where the entire universe is concentrated in a point of high density (infinite density).  According to the accepted theory, this high density state of a point, exploded violently, creating the universe that we see today.  This is the Big Bang theory proposed by Edwin Hubble in the year 1929.  The explosion that we consider in Big Bang is not at all a violent explosion, in fact it is one of the silent explosions that you can ever think of and it is neither big nor bang!  This is just a name given to the theory.  The reason is this, the space, time, sound, matter, elements and more importantly the light that we feel and experience today was created after Big Bang!  Big Bang is just an expansion of a point of infinite density, nothing more that.  But then, how do we verify this theory?

     If this kind of an expansion has happened in the past, then we must be able to detect, outer surface of the expanding sphere which contains the information of big bang in the form of light.  According to the theory, this sphere of light should uniformly exist all over the space. In a sense we have to detect the first light from the big bang.  This is called background radiation of the Big Bang.  If we succeed, it confirms the theory Big Bang.

   In the year, 1960 two astrophysics namely Dickey and Pebbles were working on the challenge of finding background radiation of the Big Bang.  They came to the conclusion that, since universe is expanding from billions of years, the energy of the photons of background radiation must be less because of the expansion in space.  (Expanding Universe:  The space and time fabric between the galaxies expand.  The light or the photon which travels in this fabric also expands.  When it expands the energy of the photon becomes less – this is predicted by Einstein’s General Theory of Relativity) When they did the calculation by using Wien’s Displacement law, they found that photon’s energy lies in the microwave region of light.
Few miles away from this group of scientist there were two more researchers from Bell Laboratory namely Penzias and Wilson designing the Horn antenna for radio astronomy.  They were trying to remove the background noise in the antenna which is detected by the detector.  No matter how much they tried they were unable to remove the background noise even-though they replaced the detector for many times.  Interestingly the detector was detecting the noise in all the direction and at all times of the day.  After their unsuccessful attempt of trying to remove this noise, they come to the conclusion that, this signal is not a noise, it is actually coming from outer space.

     Later it turned out that the noise of Penzias and Wilson’s horn antennae was actually the background radiation of Big Bang that Dickey and Pebbles were searching for!  Yes, it was an accidental discovery by two researchers from Bell Laboratory who have no idea about background radiation.  All they did was they tuned their antennae to receive a microwave radiation.  The detector was detecting first light from the Big Bang but Penzias and Wilson thought it was noise!!  The temperature of the background radiation was 3 kelvin and it was in perfect agreement with the measured value from the theory.  This is famously called as 3 kelvin black body radiation curve or 3 K curve.   Both of them were awarded noble price in physics in the year 1978 for their accidental discovery of Background Radiation.  Press Release from Bell Labs can be seen here. This observation confirms Big Bang theory.  (Big Bang theory is still a debatable theory for other reasons).

     Today we have some of the sophisticated scientific instruments in the on-board satellites which are revolving around the Earth.  WMAP (Wilkinson Microwave Anisotropy Probe) has mapped the background radiation.  The first light from the Big Bang is here….

The Light which is the sole responsible for life on earth was actually began its journey 13.5 billion years ago.

Through light on some atoms for billions of years, eventually you have life!

When Earth is close to Sun we have winter!!*

Seasons are the most wonderful thing that nature has gifted to Earth.  Without seasons, life on earth would have ceased long back.  But seasons have kept life alive on this Earth.  Changing landscape according to the seasons is the greatest beauty of nature.  Each living being on Earth can sense these changes and they adapt themselves to these changes to sustain their life on Earth. So, seasons play a crucial role in making Earth as a habitable zone for life in our solar system.

One of the age old questions is “How these seasons occur on Earth?”  Well, a fifth grade school child may answer this question. And the most celebrated answer among children is this, “Earth revolves around the Sun in an elliptical orbit with Sun at one focus.  So, when Earth is very close to Sun we have summer and when Earth is far away from Sun, we have winter.” The below image depicts what is said in the sentence.

Img 1
Seasons are mentioned with respect to Northern Hemisphere


At first stroke, this answer looks evident.  When the Earth is closest to Sun, Earth receives more sun light than at other position.  The hemisphere which is facing the Sun will have summer and the other hemisphere which is away from Sun will have winter. These conclusions can be derived from the above statement.  I studied this in my school days.  I firmly believed this explanation until I found that, this is totally wrong.  Yes, the most obvious statement that we make about seasons is wrong.  Some teachers still follow the same logic and teach wrong concept to their students!!
Let us have a closer look on how these seasons occur?

There are two motions of Earth which are evident to Img 4us.  Earth revolves around the Sun and Earth spins about its axis.  Earth takes nearly a year (365 days) to go around the Sun in an elliptical orbit and it takes a day (24 hour) to spin about its axis.  But there is a weird and wonderful thing about this axis of rotation of the Earth. (A body which rotates about its axis is called axis of rotation).  It is tilted at an angle of 23.5 degree from the vertical line as shown in the right side image. This angle or tilt is constant throughout the elliptical orbit.  And also the axis of rotation of the Earth points in the same direction at all positions of the orbit as you can see in the below image.  This direction is always towards the north.
Now let us come to our core topic seasons.  We have four seasons on Earth, summer, winter, spring and fall.


In the month of December Earth will be at position A.  At this position Earth is close to sun.  But northern hemisphere will receive less sun light than the southern hemisphere due to the tilt of the earth.  Because of this reason northern hemisphere will observe winter and southern hemisphere will observe summer!

Img 2Imag 3

But in the month of June, that is at position C the season reverses.  At this position Earth is far away from Sun compare to position A.  But now northern hemisphere will receive more sun light than southern hemisphere due to the same reason tilt of the axis of rotation of the Earth.  So, summer season at northern hemisphere and winter season at southern hemisphere.  But observe one thing; direction of the axis of rotation of the Earth is not changed.  It is still pointing in the same direction.

And the same explanation goes on for position B and D.  At position B, northern hemisphere will have spring and southern hemisphere will have fall.  Exactly reverse happens at position D.

We have got the answer!  The seasons occur on earth is because of the tilt of the axis of rotation of Earth (or Inclination of axis of rotation).

But we did not talk about the distance between Earth and Sun.  Because distance is not the cause of seasons!  Let me talk with numbers.  On Jan 4, Earth is closest to Sun with a distance of 148,000,000 km.  On July 4, Earth is at farthest point from Sun with a distance of 152,000,000 km.  The variation in distance is only 2%.  This small variation in distance cannot cause seasons on earth.

So we have seasons on Earth because, the axis of rotation of Earth is tilted. (23.5 degree).  If there is no tilt in the axis, then there are no seasons on Earth!!!

What I have learnt in school and wrote in exam is totally wrong.

Bandra to Churchgate, Vada Pav, Sugarcane Juice = I am in Mumbai

India Gate and Taj2 copy

Twenty four hours train journey in Udyan Experess was about to end at the destination at exactly eight o’clock on Sunday.  The train was slowing down; it was just one-minute stop at the Dadar railway station.  Passengers were jam packed at the exit door of train to get down.  And yes, it was not a smooth exit for Kiran and me, as we struck in the middle of the compartment with our luggage.  Within a minute, Dadar railway station was packed with thousands of people who just got down from the train.  Train almost became empty and continued its journey towards Chhatrapati Shivaji Terminus (CST) railway station.  It was a sea of people at the railway station and the foot over bridge was packed with heavy crowd with no place to climb!  We both stood aside for some time and started sweating.  After waiting for two minutes and having climbed the foot over bridge we got the first-view of our financial capital of India – Mumbai.  Our first sight was huge concrete buildings, multicolor flashing advertising boards, and crowded local market in front of us on a foot over bridge!  It’s our first few minute experience of this city, Mumbai.

Next day morning at exactly half past six we were at Bandra local railway station.  For every six minutes, local trains were transiting Bandra. The train ticket was printed with message that, we can travel in any of these trains to our destination within an hour of  the purchase.  Our journey started with Mumbai’s iconic local train from Bandra to Churchgate, which is the last local station towards the south of Mumbai.  I was in Mumbai to appear for an interview at Tata Institute of Fundamental Research Center (TIFR) for a research fellowship.  By default, our first visit in Mumbai was TIFR Campus.  Having reached the campus one hour early, we had enough time to see the campus.  The campus sits right in the middle of Indian Navy area at Colaba.  The area is called Navy Nagar.  The neat white markings, with  proper sign boards on both side of the Homi Baba road, clean-neat foot paths with less number of people walking, no shops around and an old Afghan Church was the signature of this defense area.  We both spent almost three forth of our valuable day to finish my interview at the campus.  TIFR campus was beautiful in its geographical location.   It is just next to the waters of Arabian Sea and the view of sea from campus main building makes everyone very relaxed and calm.  Undoubtedly, one of the beautiful research centers in India.  Of course we did not have permission to see laboratories and other facilities, so we roamed the entire campus by admiring its beauty. Last but not the least, we did not forget to fill our appetite at the well maintained and air conditioned canteen of TIFR!

Our next visit was to a place where King George V and Queen Marry came to India on the second of December in the year 1911.  To commemorate the landing of the king and the queen at this place, British constructed this monument in Indo-Saracenic style and is now very popularly known as Gate Way of India.  Bombay was the name given by the Portuguese who were the first intruders to India before the British.  When they reached this place they said ‘bom-bay’, which means ‘good-bay’ (good harbor) in their language.  Even today, Mumbai houses its harbor in this place.  Gate Way of India stands with the memory of Indian Independence time.  It is at this place British ended their rule in India.  After independence, the last Governor General of the British and his soldiers left India from this place.  Swami Vevekananda went on his historic voyage to Chicago from this very place.  Truly, ‘Gate Way of India’ is one of the symbols of Indian History. Even today, Mumbaikers use this place to spread peace, joy and brotherhood to the entire world.  The hundred year old heritage wing of Taj Mahal hotel adds another feather to this place and makes one of the iconic architectural signatures of Mumbai.  Kiran and I, took a bus from TIFR and got down two kilometers before Gate Way of India.  We both walked on the Shaeed Bagath Singh road experiencing Mumbai’s traffic and having glimpse of other old buildings.  Finally, we reached Gate Way of India through local roads.

Our walking did not stop even though the Sun was brutal on two Bangaloreans.  We both are in our unusual formal dress because of my interview.  It was horrible to walk in formals under the heat of sun, yet we wanted to explore the city.  The place where ‘Gate Way of India’ is located can be called as the heart of city.  When Portuguese came, they started colonizing Bombay right from this place because of the beautiful harbor they have.  And later British followed the same plan and they also implemented local trains to Bombay.  The then Bombay started to grow right from this place towards North.  The streets, circles, Indo-Saracenic architectural buildings such as Mumbai high court, Chatrapathi Shivaji Museum, Western railway head quarters at this place reflects the period of old Bombay.  Navi Mumbai located almost fifty kilometers away from this place, where you can see Mumbai Metro rail, Mono rail and other recent developments.  Even though you don’t find Metro in South Mumbai, yet it is one of the developed and highly populated cities of India.  After looking at the statue on Chatrapathi Shivaji marg, I suddenly realized that we are standing on the land of Maratha ruler Chatrapathi Shivaji. Chatrapathi Shivaji was the famous seventeenth century Indian warrior king, who ruled Maratha Kingdom efficiently with his administrative and military skills.  Most of the old buildings, a museum, a railway station and an airport at Mumbai were named after him.

Taking a local train to Marine Line railway station, we reached another signature landmark of Mumbai called Marine Drive.  Almost all the Indian movies and foreign movies which showcase Mumbai will have a scene of Marine Drive.  The beach is very shallow and curvy here.  A four kilometer double road with neat foot paths adjacent to the curved beach adds to the beauty.  Morning and evening walks along this beach are a pride for Mumbaikers as well as tourists.  With street illuminated at night, this place looks magical to the eye.  Kiran and I reached this place at the perfect time!  Evening reddish  sky and cumulative clouds are reflecting in the vast Arabian Sea.  Sun was about set- a perfect framed shot for a photographer.  Over to the camera now….

Next, we got down at Lower Parel railway station.  Twilight was fading out, here and there advertising neon lights and corporate buildings light was flashing.  After satisfying our dehydrated bodies with sugarcane juice, we headed out to the local market.  Beside Lower Parel railway station life was different.  A slum with a local market selling everything you can imagine, people buying things, eating what they want and children from slums roaming the market and a crowd of people running to catch a local train. This was the real life at this place.  Seeing everything at once was full chaos- a real Mumbai.  Just the other side of the road, huge corporate office building with beautiful sign boards, branded showrooms and a pool of Benz, BMW, Audi cars – a posh Mumbai.  Mumbai is a home to almost all kinds of people no matter whether they are rich or poor.  Our agenda is to finish our dinner in the local market.  We tasted variety of chats and their masalas in different shops and drank fruit juices until we satisfied our stomach.  Our other agenda is to walk from the local market to Worli to see the Bandra-Worli Sea Link Bridge,  country’s unique bridge.  The total distance was two and half kilometers and we had enough energy to walk.  Exploring the streets of Mumbai at night is really fun and we are ready for it.

Bandra-Worli sea link bridge was the first of its kind in the country.  It is a cable bridge across Arabian Sea linking Bandra and Worli.  Five kilometers bridge looks very beautiful from far.  My camera and tripod were busy in taking snaps of this beautiful landscape.  We were enjoying our precious time at this place but were suddenly caught by the Mumbai lady police who were in plain clothes.  We were interrogated for fifteen minutes about whereabouts.  And one lady police scanned all the marks cards and degree certificates from my file.  Even TIFR officials did not verify my documents so much, but Mumbai police did!  After all the document verification was done, they told us photography is strictly prohibited here and not to take any photos.  There are no sign boards displaying photography is prohibited, and when asked about this the two lady police did not have an answer.  They called higher officials and confirmed existing of this rule.  How on earth, we both would know that photography is prohibited at this place without a proper notice board.  We insisted them to put a notice board here, so that it helps other tourists and then left the place.  To our surprise both lady police told not to delete the photos that we have already taken!!  We took a joy ride on India’s first cable bridge by Mumbai city taxi.  Drive along this bridge was awesome but this joy ride also flattened our wallets.

On Tuesday morning we were standing at Bandra local railway station with hundreds of passengers, who were heading towards their offices.  It was a peak hour crowd at the station.  Every six minutes, train comes and halts for 10 seconds.  We both were looking all around the station, nearly thousand people used to get into the train and the same amounts of people were getting down.  All compartments were crowded heavily in such a way that there is no place to stand even at the door.  People who got down from the train were never walking, instead they were running.  Kiran suddenly said, “Mumbai never walks, it only runs.”  For south Indians, especially for Bangaloreans these are unseen visuals, yet it is normal life in Mumbai.  That’s how Mumbikers live in Mumbai.  Metallic foot over bridges are another interesting part of Mumbikers life.  Typically, a foot over bridge in Bangalore can take you from one side of the road to other.  But here the story is different; you can walk on foot over bridge for a half a kilometer and even more at some places.  All foot over bridge end at local railway stations.  Millions of people use these bridges every day.  What we observed is that the default friction-pads of metallic surface on which people walk, have completely become shiny surfaces.  The city’s civic body has welded extra friction-pads to the metallic surfaces to give friction while walking!  Only in Mumbai these kind of strange things are seen.  Kiran asked me a question, “How to travel in this crowded train?”  I told him, “It’s very simple. Just stand in the crowd, they will push you in and whenever you want to get down come near to the door they will push you out.”  It’s very easy to travel in Mumbai’s crowded trains.  Today we are heading towards the country’s oldest railway station known as Chatrapathi Shivaji Terminus (CST).

Chatrapathi Shivaji Terminus is hundred year old railway station in India.  This was built by Britsh to remember the golden jubilee of the Queen Victoria in the year 1887.  It was known as Victoria Terminus but in 1996 it was renamed as Chatrapahti Shivaji Terminus (CST).  The architecture of this monument is in the Gothic-revival style.  It was built for a railway station which had the head quarters of Indian Peninsular Railway during British rule and even after hundred years it still a working railway station and also the countries busiest railway station.  CST hoses both local and national trains.  This beautiful building also has the tag of UNESCO heritage site.  CST was also the victim brutal terrorist attack of 26/11, but no harm done to the heritage building during the attack.

Last night we both were in formals and today we became locals.  We started our journey by walk under the hot Sun after having lime juice near Azad Maidan.  We passed by Hazarimal Somani road, M.G.Road and halted near the Flora fountain which reminded us of Avenue road in Bangalore.  Yes, it’s Books!  We scanned through all the books at the stores. Kiran started searching for some exotic books and purchased few of them.  Flora fountain is also one of the architectural monuments in south Bombay.  It was erected in the year 1864 to honor the Bartle Frere who was the governor of Bombay.  It was named after Greek goddess, Flora.  Hutatma Chowk is another landmark located beside flora fountain.  It was built in the memory of members of Samyukta Maharastra Samithi who lost their  lives during the police attack on their peaceful demonstration.  The area around this place is also called as Fort Area.  This place is also famous for many other reasons.  Within a radius of one kilometer, nearly twenty eight bank’s head quarters buildings can be found!  Some of the bank buildings have unique architectures.  Bombay Stock Exchange (BSE) at Dalal Street sits right at this place.  It’s the heart of India’s financial transactions.  And for the people who work in this area, their language would be just money.  Sun has already dehydrated the lime juice we consumed and now it is time for sugarcane juice.  Mumbai’s heat was unbearable for two of us.  Sugarcane juice has almost become water for us; we drank sugarcane juice almost at every junction while walking. Later in the evening Kiran’s stomach gave a push, and then he started suspecting the sugarcane juice he had and stopped drinking further!

Sun was over head, and the clock was showing twelve o’clock.  It’s a perfect time to see Mumbai Dabba Walas at Churchgate railway station.  On the way to Churchgate station we spotted a Parsi temple.  Kiran told me, only parsis can enter this temple.  Mumbai has many parsi temple at different parts of the city and the one at fort area is the oldest of all which is three hundred years old.  Due to last night Mumbai police attack on us, we almost stopped our photography.  I feel an SLR camera connected to a tripod is the problem to Mumbai police.  Unfortunately, we did not have a normal point and shoot camera.  We just saw the temple from outside and suddenly spotted dabbas and cycles of Dabbawalas beside the road.  It was a hundred year old practice of delivering food to the customers office from their homes.  Dabbawalas collect the filled lunch dabbas (food containers) from homes and deliver it to the workplaces on time, and then they return  dabbas to home. Their mode of transport is just carts and cycles. Their unique dress code of white pajamas and white Ghandi Cap distinguishes them from common public. Their services were uninterrupted by any strike or harsh day of monsoon from the last hundred years! Only in 2011, during Anna Hazare campaign against corruption in Mumbai, they went on a day’s strike.  Except this, nothing stopped them in hundred years!  They can be spotted at many places of Mumbai during lunch time.

Seeing dabba walas with their dabbas (food containers), our stomachs started making noise.  It’s now time to taste Mumbai’s Biriyani at Bendi Bazar, which is a like a typical K.R.Market area of Bangalore.  Most of the people who live in Bendi Bazar  belong to Muslim community. Obviously, they make very good Biriyanis and lot of famous hotel can be found at this place.  One person in bus suggested us to go to Noor Mahammadi hotel to have good biriyani at decent price.  Well, what else you need for an empty stomach.  We had chicken biriyani along with Sanju’s chikken curry, a recipe from Bollywood actor Sanjay Datt.  Both dishes were very tasty and satisfied our stomach to the full.  Having gained full energy with good non-vegetarian lunch, we started our afternoon journey on an iconic Mumbai double-decker bus.  It was a joy ride for us and the bus passed by Marine Drive, Mantralayam (Mumbai’s Vidhana Soudha) and Back Bay fishing yard.  One more interesting fact of Mumbai is that except the classy cars of corporate world, all city taxies and government buses uses CNG as fuel.  To our surprise, we could hardly find any bikes on road.  Bike users in south Mumbai are almost zero.  This drastically reduces the amount of pollution in a city like Mumbai.  We know how Bangalore is polluted with vehicles, but here everything is under control.  Majority of Mubaiker’s life line transport is local trains, which runs on electricity!

Mahalakshmi local railway station is just three stops from Churchgate station.  Just beside Mahalakshmi station, Mumbai houses world’s largest ‘Washing Machine’!  Yes it’s the world’s largest Dhobi Ghat (Laundry space) attached to a slum.  A fly over beside the station will give a perfect view of Dhobi Ghat.  It sits right under the shadow of corporate world sky scrapers and apartments of Mumbai.  Everyday lot of foreigners visit this fly over just to have a glimpse of the world’s largest Dhobi Ghat.  Again sugarcane juice comes to the rescue to beat Sun’s heat while walking.  We walked along Mumbai’s race course and reached Nehru Science Center, which includes a Planetarium.  Unfortunately, before we reached the place, the last show was already running and so we could not attend the show.  Science center also had museum in the campus.  After a brief visit to museum, we sealed off our one and half day package of Mumbai.  We headed back to the place where we stayed to catch the train to Bangalore.

Our stay in Mumbai was at a crowded place near Bandra station.  Almost at all time we saw huge crowds outside the station along with series of autos piling up making traffic jam, stinking garbage besides the slum dwellers.  This is a common scene at Bandra station.  We stayed at IRCTC retiring room facility at the newly constructed and well maintained Bandra Terminus station, which is just a kilometer from Bandra local station.  And yes, when you are in Mumbai you cannot forget the favorite dish of Mubaikers Vada Pav.  We tasted Vada Pav at different parts of the city and even in our train journey.  We saw people eating Vada Pav in local trains, buses, while walking on foot paths and at many places.  It’s one of the famous traditional foods of Mumbai and is available at all parts of Mumbai.  Before coming back to Bangalore, I renamed this dish as “Mumbai’s Burger!”

India Gate 3 copyMumbai is a city of many signatures and a place which can take you back into history.  When a train halts at Mumbai, thousands of people pool into the city aspiring of their future here.  It’s a home to almost all kinds of people.  Country’s biggest apartments, multi-storied individual residences, beautiful corporate building and the largest slum of Asia, all have their address as Mumbai.  It’s a city which is carefully packed with rich as well as poor at the same place!  And yes, it is also the home to the world’s richest cinema industry known as Bollywood and also the financial capital of India.  You cannot explain Mumbai through words; you can only experience it.  We stayed only for two days in this city and out of these only one and half day we were able to wander the city (only south Mumbai).  Right from the Mumbai Police, we experienced most of Mumbai’s life.  If you ask me to choose the best experience in Mumbai, I will choose local trains of Mumbai.  For me Mumbai local trains are the nerves of Mumbai’s brain.  For Mumbaikers, local trains help them travel from one part of the city to other in a faster way, but for outsiders, this journey reflects the life of Mumbai.  In this journey, you can see joy, young love, business, poor people, student life, office life, jam packed ladies compartment and a very calm foot board lady travelers etc., -Absolutely amazing! And you cannot see these scenes everywhere in India except in Mumbai.  We missed many important places in Mumbai, yet our experience of Mumbai is not small.  Mumbai is a magical city.  In my view, “tourists visited Mumbai” is wrong.  It’s the other way; Mumbai makes tourists visit it!  I am waiting for my second trip to Mumbai.
