F 1 ?!! Interesting facts

F1 Car.... some facts

01. An F1 car is made up of 80,000 components, if it were assembled 99.9% correctly, it would still start the race with 80 things wrong!

02. Formula 1 cars have over a kilometre of cable, linked to about 100 sensors and actuators which monitor and control many parts of the car.

03. An F1 car can go from 0 to 160 kph AND back to 0 in FOUR seconds!!!!!!!

04. F1 car engines last only for about 2 hours of racing mostly before blowing up on the other hand we expect our engines to last us for a decent 20 yrs on an average and they quite faithfully DO....that's the extent to which the engines r pushed to perform...

05. When an F1 driver hits the brakes on his car he experiences retardation or deceleration comparable to a regular car driving through a BRICK wall at 300kmph!

06. An average F1 driver looses about 4kgs of weight after just one race due to the prolonged exposure to high G forces and temperatures for little over an hour(Yeah that's right!!!)

07. At 600 kg a F1 car is less than half the weight of a Mini.

08. In an F1 car the engine typically revs upto 18000rpm,(the piston travelling up and down 300 times asecond!!) whereas cars like the palio, maruti800, indica rev only upto 6000 rpm at max. That's 3 times slower.

09. The brake discs in an F1 car have an operating temperature of approx 1000 degrees Centigrade and they attain that temp while braking before almost everyturn...that is why they r not made of steel but ofcarbon fibre which is much more harder and resistant to wear and tear and most of all has a higher melting point.

10. If a water hose were to blow off, the complete cooling system would empty in just over a second.

11. Gear cogs or ratios are used only for one race,and are replaced regularly to prevent failure, as they are subjected to very high degrees of stress.

12. The fit in the cockpit is so tight that the steering wheel must be removed for the driver to get in or out of the car. A small latch behind the wheel releases it from the column. Levers or paddles for changing gear are located on the back of the wheel. So no gear stick! The clutch levers are also on the steering wheel, located below the gear paddles.

13. To give you an idea of just how important aerodynamic design and added downforce can be, small planes can take off at slower speeds than F1 carstravel on the track.

14. Without aerodynamic downforce, high-performance racing cars have sufficient power to produce wheel spin and loss of control at 160 kph. They usually race at over 300 kph.

15. The amount of aerodynamic downforce produced by the front and rear wings and the car underbody is amazing. Once the car is travelling over 160 kph, anF1 car can generate enough downforce to equal it's own weight. That means it could actually hold itself to the CEILING of a tunnel and drive UPSIDE down!

16. In a street course race like the Monaco grandprix, the downforce provides enough suction to lift manhole covers. Before the race all of the man hole covers on the streets have to be welded down to prevent this from happening!

17. The refuelers used in F1 can supply 12 litres of fuel per second. This means it would take just 4 seconds to fill the tank of an average 50 litre family car. They use the same refuelling rigs used on US military helicopters today.

18. TOP F1 pit crews can refuel and change tyres inaround 3 seconds.

19. Race car tyres don't have air in them like normal car tyres. Most racing tyres have nitrogen in thetyres because nitrogen has a more consistent pressure compared to normal air. Air typically contains varying amounts of water vapour in it, which affects its expansion and contraction as a function of temperature, making the tyre pressure unpredictable.

20. During the race the tyres lose weight! Each tyre loses about 0.5 kg in weight due to wear.

21. Normal tyres last 60 000 - 100 000 km. Racing tyres are designed to last 90 - 120 km (That'sKhandala and back).

22. A dry-weather F1 tyre reaches peak operating performance (best grip) when tread temperature is between 900C and 1200C.(Water boils at 100 C remember)At top speed, F1 tyres rotate 50 times asecond.

Heater inaugurated :) Winters welcomed !!

I was studying peacefully at home and was feeling some cold when Vishal came from outside and switched on the heater anouncing its inauguration !!
The temperature dropped dlike anything here.....
It was approximately 25 deg C outside yesterday and its estimated that it will be 4 deg C at some point of the time tonight.


So we hereby welcome the winters....:) sweaters / jackets are on...and sitting at home is better than loitering around....

There are chilly winds around and rains are expected as well. All this is bizzare but not unprecedented. Thought it has happened suddenly so has surprized me :) Anyway....coffee at home with thermodynamics :) what else can heat up more than that ?

And then Vishal has inaugurated the heater too !!!

Case for dangerous optimism - by R. A. Mashelkar

In the morning today Raghu was chatting with me and many thoughts were flowing in my mind. One of the questions he asked was whether I was planning to return to India. In the evening I got this wonderful article from Animesh. So thanks to him.

Case for dangerous optimism
Dr. R. A. Mashelkar
The writer is Director-General, CSIR http://www.tribuneindia.com/2005/specials/tribune_125/main16.htm

The tasks ahead of us will be decided essentially by the future of theIndia that we foresee in 20 years. It is important to envisage a future for the India of 2025. It must be realised, however, that visualising the future could be a very hazardous task. Twenty five years ago, there was no WTO, no European Union, no AIDS, no laptop, no Internet, no mobile phone, and so on. Yet, all of them dominate our lives today. No one would have predicted any of these 25 years ago. Therefore, it is difficult to hazard a guess as to what India will be in 2025. Despite this, predictions have been made about India's future. Goldman Sachs has predicted that by 2050, the US, India and China will be the three topmost economies in the world. In a recent paper that I have written in the prestigious journal Science, I myself predicted that if India plays its cards right, then India could be the global knowledge production centre for the world in 2025.

NEW HORIZONS: The future is IT — Indian Talent — in all walks of lifeWhat gives me this confidence? I have often said India's future is 'IT'. And by that, I do not mean IT as in Information Technology but IT as in'Indian Talent'. It is this talent in all walks of life, including inscience and technology that is going to give us the leadership position.Just see, what is happening around us. During the last six or sevenyears, more than 150 major companies from the US and Europe have set uptheir research, design and development centres in India. They include big names such as Boeing, Daimler Chrysler, DuPont, General Electric,General Motors, Intel, IBM, Microsoft, Siemens, Unilever and so on. Some of them employ 2000 to 3000 researchers. Why is this so?The answer was given by the legendary Jack Welch, former CEO of GeneralElectric (GE) during the inauguration of GE's R&D Centre in Bangalore. He said "India is a developing country but it is a developed country as far as its intellectual capital is concerned. We get the bestintellectual capital per dollar here". Brain gainThis attraction of high intellectual capital per dollar is driving another phenomenon: The phenomenon of 'brain drain' turning into a phenomenon of 'brain gain'. The world acknowledges today the high calibre of Indian scientists, engineers and technologists. The obvious proof of this is the fact thatwhile products of a few other Indian enterprises command internationalprestige and price, the products of our higher educational institutions are in great demand internationally.

The contribution of Indians to thegrowth of science and technology in developed countries has been widelyappreciated. Can we not then garner all these energies and contribute tobuilding the new India in a Team India spirit? I believe we can. I expect Indian science to achieve many milestones within the next 25years. For example, we have already achieved the Green Revolution. But I expect India to move forward to achieve the Evergreen Revolution byushering in new biotechnology. This would mean moving from Green Revolution to Gene Revolution.

India should become a country that not only provides food to its own people but also to those poor and developing nations around the world that have a food scarcity. In health technology, I would expect India to scale many heights. In the area of drugs and pharmaceuticals, so far, Indian companies grew by copying the drugs that were discovered by the western world. But Indian industry has moved from imitation to innovation now. This will have a big pay off. It is true that so far not a single new drug coming from India has captured the world market.

However, I expect India to come out with several new drugs, which will assume a dominant position. Is thispossible? I do believe so. As we know, through CSIR's New Millennium Indian Technology Leadership Initiative (NMITLI) Programme, a new TB molecule has been already developed by Lupin in association with so many other Indian institutions. After Rifampycin, this is the first newmolecule on TB to arrive on the scene after 1963. Inspiring examples like this give us the confidence that we can do it. The rich nations and multinational companies are not investing in drugs for the diseases of the poor such as tuberculosis, malaria, etc.

By 2025, I expect India to become a major provider to the developing world of the drugs for the poor. We have remarkable achievements in information technology. By 2008, 35 per cent of our exports are expected to be based on software, and all this will be achieved by 6,00,000 young people, whose current age is just 26 years. I expect that India will build on this platform and develop the next generation IT industry, which will be based on not just providing routine services or mundane or off-shore jobs but based onstrong, new IT products.

By 2025, I expect India to earn the reputationof a country, which has used IT not only for creating wealth but also for a meaningful social transformation. Let me explain what I mean. I expect information technology to make a major dent in tele-medicine, tele-education etc. Already ISRO's EDUSAT(Educational Satellite) is designed to support education through low-cost segments and to reach the un-reached people of India. I expect it to bring quality education to all parts of the country. Imagine, teachers from Pune University delivering a lecture which can be heard inreal time in Samastipur in Bihar. We can enlighten the entire nation through the power of IT.

Indian biotechnology industry is presently growing at the rate of 40 percent per year. If this growth continues, just as in IT, we can become a biotech superpower. Our key advantage will be in agro-biotechnology, health biotechnology and industrial biotechnology. I expect that in many areas we will make major breakthroughs. Stem cell research has clinical application in heart, eye, pancreas, liver, kidney diseases and spinal injury. India may emerge as a major leader in stem cell research considering the comparative advantages we have.

I expect a major shift in our energy consumption pattern. For instance, with oil on its way to $100 per barrel, non-renewable energy will get a new thrust. The use of bio-fuels will not only reduce our dependence on import of oil but will also bring the benefits of environment, ecology and employment. We have 186 million hectares of wasteland. If we planwell, then by 2025, it is possible to bring 10 to 20 per cent of thisunder cultivation of plants that can yield bio-fuel. This is capable of providing a major fillip to India's quest for a clean fuel.

Nuclear missionSOUND VISION: Indian science is set to achieve many milestones. In the strategic areas of space, defence and atomic energy, we will achieve many milestones. For example, our nuclear scientists have done us proud by having some spectacular success in fast breeder reactors. They have a dream to provide 20,000 megawatts of nuclear power by 2020, making India a leading nation in the use of nuclear energy. I expect them to fulfil this mission and that too with the distinctive stamp of our own technology. As we grow in stature and power, countries like the US are already changing their stance. Both the US and recently the UK, have agreed to be partners with us in all civilian nuclear energy programmes. Otherswill follow, too.

These nations would soon start realising that ratherthan putting sanctions on India, if they would become partners with us, then it is not only good for them but for the whole world. I have the reputation of being a dangerous optimist. When I delivered the presidential address during the Indian Science Congress held in Pune in 2000, I had painted a picture of our future and said, "Indian braindrain has been completely reversed. In fact, India is in an enviableposition of having a queue of American and European scholars waiting tojoin its unique global knowledge production centres in India". This looked like a crazy dream. But, just see, what is happening around us.Out of 2400 professionals in GE's R&D Centre in Bangalore, 700 of them are young Indians, who have decided to leave the US and join this Centre. I spoke to the President of NASSCOM, Dr Kiran Karnik, recently.He told me that during the last three years, more than 25,000 professionals have returned from abroad, around 90 per cent of thembeing IT professionals. I expect this trend to continue as India becomes a land of opportunity and provides better personal and professionalcomfort levels to its returnees.

Among all the tasks ahead of us, two are of primary importance for me. The first is to use the power of science and technology for the upliftof the poor and downtrodden and not just a privileged few. Secondly, we must make scientific temper a part of intellectual, emotional, socialand cultural life of our masses, not just a select few. If this happens, then India would become a model for other countries to emulate. I have no doubt that this dream will turn into a reality.— The writer is Director-General, CSIR..

E = MC^2

So, as science has progressed, it has been necessary to invent other forms of energy, and indeed an unfriendly critic might claim, with some reason, that the law of conservation of energy is true because we make it true by assuming the existence of forms of energy for whichthere is no other justification than the desire to retain energy as a conservative quantity.
– Kenneth S. Pitzer

What is astonishing in the realm of science is the opposite of what is astonishing in the art of the conjurer. For the latter wants to persuade us to see a very simple causality where in truth a very complicated causality is at work. Science, on the contrary, compels us to abandon belief in simple causalities precisely where everything seems so easy to comprehend and we are the fools of appearance. The ‘simplest’ things are very complicated—a fact at which one can never cease to marvel!
– Friedrich Nietzsche

Physics and Science ?? It has progressed a lot in terms of fabrications of lots of systems, machineries, level of sofistication has increased manifolds in terms of computation! Also people have successfully defined the theory of stars, blackholes etc etc...BUT !!!! It is equally true that
-there wasn't any equation given after Einstein's E = MC^2 which is EQUIVALENT in QUALITY and SIMPLICITY !!

Meeting with Professor Kuech

Sorry no interview this time readers :) Only this description and that too mixed with previous day activities and other things which are coming in life.

One of the best meetings ever happened with me in which the professor told me so many things about the research in general and intricasies of the research in his group.

Professor Kuech is the senior-most professor of the department of Chemical and Biological engineering. Most of the things I asked him were about the research which is done under him, about his groups, about his planning of reasearch, about his simplicity in research, and about his focus on the industrial develpment.

Apart from that, day flew in assignments, in meetings and in the office. Assignments kill but they teach as well.

Yesterday Andy extended his B day with so many pizzas and then we had a wonderful antakshari.....

Photography is yet to come in life. I planned for it today but again some end moment activities came up and then there was no sunlight. Hope to get to the camera soon.

Meeting with Professor Paul Nealey

(No anxiety this time)
I happened to visit him at his office with an appointment.
This is how it went:)

Rohit: Good afternoon Sir!
PN: Welcome! Rohit ! So how are you finding and what is your academic background ?
Rohit: I come from ITBHU Varanasi and I have worked in Dr Reddy's Labs after graduation for an year. Now I am inclined towards doing research in simulations.
PN: Well ! Have you met Prof Pablo ?
Rohit: Yes I have. Had good interactions with him.
PN: His groups is one of the best groups in our department if you want to do simulations.
Rohit: Please tell me the philosophy and projects of your groups and how do you find yourself different from other groups ?
PN: We are focused on applications of block co-polymers and applying verious techniques to their research and development. ( Dr Nealey gave an example which could describe how chem enggs are different from polymer physicists. ! ) Now coming to how our group is different, we mostly do lot of experimental work and then there is always lot of interaction with the de Pablo group. They come up with simulations, and then we apply those thigns on a experiments. Sometimes it is the other way round. So lot of collaborative work happens amongst the two groups.
Rohit: How does the planning happen in your group? Do you decide the targets, and solve the problems, are you oriented towards research which is going to help the industry sooner or later or are you contributing more to science ? I see there is lot of difference between the philosophies of industries and academia as well.
PN: There are two extreams: One is focussed towards targeting the problems which are not solved in the industry. We can target those and then come up with solutions.
The other is trying new things which have not even been conceived but because lot of things have to be searched, and are not in existence, probably lots of applications are not known! These I would say are two extreams and we are not into any of these. We are a between the two. We look the open ended problems in the industries, and also try lots of new things and experiments on the things which might later be useful in the industries say after 5 years or 10 years !
Rohit: Actually I also find myself focused towards doing research which suppports technology and not simply contributing to science.
PN: Sounds good!
Rohit:When I compare simulations and experimental work I would say, one should have some part of experimental work and hands on experience of that as well.
PN: I put it like this: If you want to be best in something, then you should do only that. Its good to have motivation like that also. You can work on experiments, get hands on experience, then model and simulate the things. Probably that is even better as that gives you much idea about what techniques to be applied to the simulations. That sounds even great!!
Rohit: Sure sir! I think I will be doing some similar project in future. Though I am not decided with the research guide till now, but these two groups have interested me most because of the 'lithography'.
PN: Thats great !
Changing topic

PN: Well you are the first student from your institute actually. And looking at the applications etc, I find it little tough to judge what it means to be in the top 1.5 % of 150,000 students! Well they are actually equal !
Rohit: Ya more or less they are marginally different, and because it is one of the toughest exams so all are good! In fact, there isn't much difference in them.
PN: basically its also difficult for us to figure out how the institute compare with each other in India also ! How do YOU rate institutes in india? ! Which is the best IIT?
Rohit: In terms of the focus towards research, as far as I know, IIT Bombay is the best ! But we dont compare as such becuase the only difference is in the orientation towards a particular thing. That can be industry, or research or a combination etc. ( as sunil also keeps telling)
PN: Ya I also think so !IIT Bombay is the best! How is bombay university different from IIT ?
Rohit: Bombay university is focused towards applications in industries so those ppl find themselves fitting good in industries, whereas ppl from IIT Bombay fit into research better( Actually these are my perceptions and then there are people from both institutes which do good in both places. ) Well!! Is it the case ?! And do you find IITians from Bombay better than other students?
PN: ya !! IITians are definitely better but then all IITians are equal !!!! !
Changing topic again Well but how do you people happen to select the research institute and fields of interest.
Rohit: There are actually two extreme ways people do that. They either select an IIT and then fill all branches in the pref list or they select the field and fill the IITs after that, and then many do a combination of these. So its different from what people do here ! ( In between Prof PN also started giving the same opinion)
PN: ya...So have also cleared the IIT exam ? I am sure you are as good as people from IIT Bombay :)
Rohit: Ya I took the same exam ! Don't know if I am that good, But I will try to do good always. In fact for the reason that I am the first student from my college in chem engg, I would try to make a mark. I guess that helps you taking more students from my institute ?! Does it ?!
PN: Ya it surely helps. !! And we will take more students from your institute ! Also I thank you for all this feedback ! Do good here. I shall keep asking you things about your country !
Rohit: Thanks a lot ! :)

In between I asked for papers which he mailed right there.

That was an interesting meeting.

Homework and assignments coming the way

Thermodynamics homework :)

Meeting with Prof Marvelias - Today 2:00 PM
Meeting with Jugal and others - Today 4:00 PM

Group meeting of Prof Dumesic- Monday 8:00 AM
Meeting with Prof. TF Kuech - Monday 2:30 PM.

Social time = tending to zero (Sunday - Andy's party or something of that sort. ? )
Blog time = just to write this crap

Homeworks rock now....:) not I :)

LOVE

Even though Complete thermodynamic information is contained in one fundamental equation, or is contained in two equations of state, or in the dependence of three second order derivatives on temperature and pressure, love can not be described with any such equations.

Such equations do not exist for such a quintessential thing as love.

Running Guassian Now !!

Today was a busier day. It went in seminar which was very interesting and the topic was Protein Crystallization. I feel like posting a big blog on that but no time really...:)

Meanwhile....
I happened to learn this new software which can find the exact structure of a molecule which it will take minimizing the Gibbs Free Energy ! It can do this for lot many complex structures though I have done that for a very simple molecule called n-Butane.

DNA and other complex molecules aer designed with this software in the same way. Once the structure is made with drag and drop option, and adding particular atoms to the structure, the software is run and it minimizes the free energy of the molecule and adjusts the bond length's angles etc.

Hope I do the same for other complex molecules like DNA in near future. :D

I happened to do the same for a fullerene structure called C60. I happened to attach two hydrogen atoms on two carbon atoms of the structure, and then ran it to minimize the free energy. It made it so distorted that the football became a rugby ball...!!! Sometimes crazy things happen in that.

More to come on this soon.

Happy B Day Andy !

Today we had Anand's B day celebrated at his house.

11:50 Almost Midnight. Assignments pending. But !! Andy is a friend!! Guys and gals started collecting at his house. We were Shank, Vishal, Prateek, myself, Sriram, Daphne, Shubhika, Isha and Namrata and Sunil! Difficult to judge if guys and gals took pains to come to actually celebrate andy's b day or it was the cake that pulled them to oak tree. Sometimes in my case, I have found cake to be the dominating thing :D

So ...here we go....in american style...:)

Food first: Sunil did a great job by purchasing the big chocolate cake, making fruit custard and we had ice-cream and coke etc. Sunil...you will get a foodie wife don't worry...I sometimes think who is going to be such a lucky gal :) I scream...You scream...we all scream...and Isha screams even louder and keeps and can keep screaming...for Ice-cream....But dear Andy ( In american accent- Andae) ! if you happen to read this blog( of course I will ensure you don't miss this)! don't guess I was there for the cake :) I was there for you dude :D (Let the inside feeling only come out of me that I was there for cake).

Gifts:
(Lucky Andy) Isha, prateek and Sriram brought a very nice greeting card on which all of us signed ( does it increase the value of the card for you andy ?) and some gifts for Andy. So thanks to them :) Andy you have thanked them already right ? All these are investments made for returns dude...so don't forget to treat them :)well. Remember they haven't taken Indian food since long. And we miss pizza...:) Sunday is a good day always Andy!

Photography:
Sriram and Shank have done that job, so I hope we all get to see some of those snaps soon. If you happen to upload them to yahoo Shank, please let us know the link :)

Games:Dumb C the only popular game amongst these guys and gals...:) Shank really made us laugh...out loud...:) Keep doing that till you are here...:)
And it was almost 1:40 by the time most of us started feeling sleepy...so we all left and left the things to be cleaned by Andy( Sorry dude its difficult to do that at midnight...:) I might have helped you if it was day :D But !!!!!!! haven't you collected these sweet memories for ever ? I am sure you have :)
Andy! I hereby wish you a very happy B day dude ! Long you live....big things you do...! God bless you :) Don't bother to say thanks :D
~dont expect any gift from me...this is the best I can do...:) ~ R

Meeting with Prof Juan J. de Pablo

At 10:58 Rohit and Sunil are standing outside anxiously waiting for the professor. (10:59 - here he comes)

Prof JJDP: Hi! So guys what can I do for you ?
Rohit: I had an appointment with you at 11:00. ( JJDP checks his digital diary and says ya!! Rohit ( roheet)
JJDP: What about you Sunil ( Suniel) !
Sunil: I have also come with him though I don't have appointment. I wanted to meet you about the research going under you.
JJDP: If you want to see me separately you are welcome to do that.
Rohit: If it is fine for you to have a combined meeting, its ok for us.
JJDP: If it is ok then there is no problem ! So Rohit tell me about yourself
Rohit: Well I did my UG from ITBHUand then I worked in Dr Reddy's Labs for one year where I worked on two main projects. Both were erection commissioning projects one on solvent recobery and the other was on a new pharmaceutical entity. We could fabricate chromatography systems in-house and those worked successfully. I was involved in the R and D of that.
JJDP: What about you sunil ?!
Sunil:Well I have done my Undergraduation from UDCT Bombay and I don't have any prior work experience ( JJDP confused about this college and asks to clarify if that is IIT ?) Sunil clarifies.
JJDP: So Rohit! what has interested you in our projects?
Rohit: I see simulations as a powerful technique to generate data and find good results to problems that might be difficult to solve in lab. As it is well defined and can be applied to lot many systems. As the basic principles applied to each project are the same, I don't see the different projects from the point of view of solving the typical problems. I see them from the point of view of learning techniques that can be applied to the general problems in the similar manner...
JJDP: Ya you are right! Mostly all projects have similar fundamentals. Sunil? What about you ?
Sunil: I have inclination towards interfacial science and I want to apply the techniques to it.
JJDP: Good ! Is there anything in particular you want to know about things ?
Rohit: Sir I wanted to know about the working philosophy of your group: I see it as a self driven group. Whether you are there or not, or whether you meet them once in a month's time is ok for them. Is it the case ?
JJDP: Well Rohit ! We have formal meetings.
Rohit: Sir We would like to attend some meetings of your group.
JJDP sure come on wednesday.
Rohit: How do you typically change the problem statements which you progress during the research.
(JJDP Asks for an example! )
Rohit: When I was working in DRL, It has happened that we found ideas that could affect the month long work we had done, but because all those were improvement ideas, so those were implemented. Some were dropped.
(JJDP Clearly understanding what I meant) : Ya here we have well defined problems and typical things to be done in durations and when sometimes you get me ideas which are different I am the one telling whether it is going to work or not. So typically initially we have simpler problems and when you progress, you develop skills in yourself to do that kind of judgement. Mostly the work that is done in our group is theoretical and sometimes experiments are also carried out in parallel. Sometimes I happen to meet my students more often and that too for longer durations of the order of an hour etc.....As in case of Manan, we are reaching a landmark and paper has to be completed..so we happened to meet for about an hour recently...and there were more meetings in the past as well...
Rohit : We would also like to read a few papers that you have published.
JJDP: Surely go through the papers on our group homepage and come back to me as you narrow down your choice of research advisor.
Rohit: Sure thing ! Thanks a lot
Sunil: Thanks a lot !
Rohit: We meet in the group meeting again.

Woodmans

Woodmans is one of the most visited place in US. As it is a shopping mall. Its different from Hyderabad central- my dailyl visited mall. It was in the center of the city. Woodmans however is in the outskirts of the city. The philosopphy of shopping malls is different in India and in US. In India they want these big malls to be filled with people. Whether they buy or not doesn't matter. In US the malls are always outside the city and only those people go there who have to really buy the things.
Central was as big as woodmans but items sold/ customers visited would be much lower. Here everyone who goes purchases something.

We take a bus from our hostel to West Transfer Point from where we take another bus to Woodmans. Even that is an activity which takes 4-5 hours of our weekly schedule. Still trying to figure out how this can be optimized !

Another favourate shopping mall is Copps where we get most of the grocries at almost the same price.
For all electricals and appliances and items of usages, there is Walmart- world's largest retail chain.
Hope Walmart opens a mall in India soon :) Happy shopping. :)

Very Few Thermodynamics Under Graduate Students Have Passed

Very Few Thermodynamics Under Graduate Students Have Passed.
This sentense has something to do with a pnemonic technique. An under-graduate student might get some worries reading that in a book of thermodynamics, but the interesting fact about this sentence is that first letter of every work stands for one of symbols of following crucial quantities which are always related to each other and describe the various equations of state.

Volume
F ( Helmholtz potential)
Temperature
Internal Energy
Gibb's free energy
Entropy
Enthalpy
Pressure.

One of the best pnemonic technique I have seen so far :)
Maxwell relations can be derived from the square- coming soon.

Sunil came to my house. This is how the things started to happen- We were doing the thermodynamics assignment together and it is such a wonderful subject that I feel hungry after that. We started to make something and then went into cooking spree. Imagine when two chem enggs meet what happens.

Our practical conversations !

" Sunil! cut the potatoes smaller, that will increase the surface area and heat and mass transfer will be better!"
" Rohit, put the reactor ( pressure cooker) and subject it to high temperature initially later when the pressure is builtup keep it at constant with minimum heat"
" Put a cover over the sabji being cooked and pour some water at the top of it. Lets operate at total reflux "
" Hey sunil!! You forget that you have to do waste management too" Throw all those wastes trash....(dustbin)."
"Why not making a suspension of the potato starch/ Corn flour and then try to coagulate the particles in the heated oil and at the same time embedding the bigger particles so that the reinforcement happens ( pakaude ban gaye !) And so on....:) "

" Rohit ! I think the vapour pressure of water will meet atmospheric pressure soon, so lets add some salt and increase the boiling point itself. Rice will be cooked faster ! If you want, you may utilize the floating vegetables to get homegenized sooner so lets optimize the mixing as well"
