Life : Little Hope

   It is a long time since I first smiled and feel happiness by achieving my goal but after than till now, I have been heart broken so many times due to my ambitions. It is not just because I didn't make enough effort to make things happen but also with the situation and environment I grown up make me feel down all the time. Every time when I got a setback , it was related to my past or something that other students did long time ago in their childhood and I am just regreting it now because I am way back in time living in a present. To be real, I am interested in science and I  love researching in a lab, working on something truly novel which can impact our lives but every time I see that dream, It gives me a sensation to be realistic because I am financially poor person. My father is a hard working man who brings average salary to satisfy basic needs for my family and here is whole story of my life :

         I am shubham, little bit ambitious student, studying engineering in one of a premier institutes of India. Although it seems to be fascinating but trust me guys, it is not cool, especially in the case of me.  I have finishied my primary education in a small town in local language medium and therefore I never developed a true sense of English. The first 16 years of education was nothing but in a local language medium named, 'Marathi'. It is state language of Maharashtra and usuallu enough for  all communications limited in Maharashtra. However, when I started my engineering studies in NIT Trichy, it was a drastic change for me. I even remember when I came to tiruchirappalli with my father for official admission confirmation. It was noon time, I came out of train after a long journey for about 28 hours and first thing that I heard was an absurd langauge that I never come across before. Giving a circumstances of those time,  It was my first time outside of Maharashtra. It was the first frozen experience of my life which introduced me to new environment and adapt to the surroundings and I believe that it is my first regret which I am lagging behind compared to my peers (lack of travelling/regional experience). I am surrounded my many students coming from different background but I always heard about their childhood, teenagers travelling, trips abraod and many more but when discussion comes to me, it feels to be cold and ashamed of the places or region I came from and how I have lost that joy in first 16 years of my life. Sometimes I feel that it might be a fault or mistake that my parents made but reality is there never could have sustained that in those time. My parents struggeled alot for me , even for my education , health and well being. I believe that they have done their best to make me a person I am today but somehow I could never neglect an idea that what I would be if I could have those experience.  It is kind of human nature that no one could defeat but the strange part is regret doesn't end at one point. It comes in every failure I have ever encountered. Here is little story that happened in last couple of years that changed my life :

        In starting year, I was really shy, no self esteem. No one knows my name. I have been a part of group that is last things I ever wanted and everything was ok, going as usual.  Started making friends, but as I am financially poor, I always thought about saving money for necessities and never got a chance to be independent. Let me tell you what happened in childhood, I wanted to learn keyboard, drum but my father refused several times, beaten couple of times for my haughtiness but I never made it to learn. When I remember that scenary today, I feel that my father was a goal oriented person, always wanted to educate their sons through top institutes but never supported flowing in a music or any kind extra literature reading that could distract me from studying syllabus.  Another reason might be they didn't have enough money at that time to pay for music classes. I think that it was second regret in my life that I will never forget. I lost those years just studying syllabus and making awesome friends. That is a reason, I was so shy and didn't have much music experience that could interest people around me. This is because all of my roommates had an amazing story to tell and I didn't but still I had this little hope that everything will be fine. I started listening to english albums, first time in my engineering life and I have little hope that I could sing a little but not that I can compete with someone. 

  As studying was so easy for me. I used to read books from library, out of syllabus to learn and explore a concept in engineering subjects that could fascinates me. I was so busy in my first two years studying syllabus as well as extra syllabus that no one ever wanted to study except me. I haven't tried sports either because I have to ask to my father for tennis racket that I could purchase in order to enjoy but I always had this feeling that my father took a loan for my study and observing my families condition, I have made several decisions of my life, I could not help.  I wanted to go for a trip but tell my friends that my father wouldn't allow me to do that, just for a sake of condition I  was dealing with and I imagine that if I could from a rich family , my life would have been better. I think , this is one of my regret I could never forget but couldn't help it.

    The only one thing happened to me that was good as I could manage to get good GPA in academics, average one that is enough to make me happy but after dropping honors in fifth semester, I realized , I should stop studying that hard and try to explore my passion interests that I could make a significant impact and I did went to Canada to work on project that I would love to, but after coming from Canada, I realized that I am lagging in something that I was not aware of. All the time, I thought, it will be fine but I never thought that it could distort my life upside down. You may laugh at me but I am really bad in writing especially which is not realted to science. It is becuase I never tried or worked on writing other than science. Even though today, It makes me miserable all the time , when I start writing about History it is really a challenge for me. That is why I couldn't score more in GRE as well as in TOEFL. With extremely low score in English made me realize that I could have done better if I was aware of my weak point and that is most severe regret that I had as I may not been able to make it in future. At that moment, I dropped every ambitions that I had, my dream if researching in top universities in US and everything about research made me feel a big mistake I have done in my life. I could have taken placement and worked for a company but I didn't have that option either. So everyday now , I struggle to find opportunities I can work and simulteniously improve my English but sure it will take time to improve.  When I hear about good news about my friends getting admit offer from top US institution with scholarship it makes me realize the fact that I have done by best to apply and pursue my dream but eventually it gods will, I think I could have done better if I could have an education in English medium in my first 16 years. That one thing made me suffer all those loss that I am regreting everyday but still I have some hope that even though in future, I will not get admit from good university, I still pursue my passion but it needs a great courage to make things better on your own. I still have little hope to try for the things that matters to me. 

Let's see what happens next........ !!

Design of Jumbo jet : Rolls Royce

One of greatest engineering marvel , building jumbo jet engine is excellent piece of precise piece of engineering. This is plan for building one of greenest engine to compete with highly powerful company General Electric (GE). This company was also building cars but its after sold to BMW. The real heritage of company is aircraft machines started from building concord to break mach record in early nineties. Let's now talk about design of jumbo jet engine, This engine is assembly  consists of thousands of parts  with eight separate sections in assembly. One of interested part in assembly is fan blade of jumbo jet engine  which provides 75 percent of engines thrust and propels around 1.2 tonnes of air per second. This fan blade is unique feature which makes it different from earlier turbo jet engine.Manufacturing of this blade is secret of company which is prepared by inflation process in which  specially made sandwich of two titanium blades with special material embedded inside it . Then it is heated upto secret critical temperature. This will inflates inside embedded material to take special aerofoil shape of the blade. The another massive part is manufactured for jumbo  jet is massive case of jumbo jet.  One of challenge to such heavy load on blades is how to join blades to hub of engine. The highly specialized TIG weld is used to join it precisely.  The another type of tiny blades is used after the combustion chamber operates at 1700 degree celsius. To operate at such high temperature  about 300 degree above melting point of material (Titanium), it is very important to avoid melting of blade. So software modules is used to design cooling system to take away heat to safe level . Generally optimization in industry comes as for material for particular design. So material scientists will tests different composition of alloys and tests its performance by looking at microstructure of alloy. Manufacturing of this tiny blades is done by growing single grain in spiral shape tube. When in the microstructure of material , grains are oriented in different directions are not very strong but when they oriented in a single direction it possess enormous strength in that direction.  This concept is used in how tiny blade sustain such high load which creates power equivalent to average super sports car at temperature above its melting. After the harsh crisis in 1970s, bank corrupted the company . Then in starting 1972, then flew aircraft with their jet engines, makes huge change in company, Even today, the basic design of jumbo jet engine is quite similar to design of engine in 1970s.  The dream of company comes to reality in first flight of boeing 787 with rolls royce jumbo jet engine. It is one of incredible projects in history in case of jet engines. Reference  :    https://www.youtube.com/watch?v=VfomloUg2Gw

Product Design : Biomimicry

      Most  of  optimum design human have been searching till now has found astounding relationship with design nature of creatures exists on our planet.The biomimicry means sustainable innovative design inspired by nature especially organisms. For example, the famous engineer J R West, He is one of member involved in design and making of bullet train has faced the problem of sonic boom when such high speed  train above Mach one entering into the tunnel. Still the most important thing is while solving that problem he was come across a film of kingfisher . he thought about design of bill of this bird that this bird travelling from low density to high density medium without even disturbing high density medium (where air and water are low and high density medium). This can be used to design front bonnet of train such that it will reduce drag drastically causing 10 percent faster speed and 15 percent if less electricity. One might be familiar with company name called solid thinking. This company has used algorithms which is found in growth of trees and bones called bone growth algorithm which is one of project in stanford university. This tool is extremely helpful for light weight designs of automobile,bridges and heavy civil structures by giving optimum structures in the form of beams. I also learned this tool called inspire software made by solidthinking. Off course this is not opensource software but if you want to have some experience with this tool, you must download trial version of this software. I loved this tool like the way its giving beam like structure for given load application on assembly. If you are lovers of automotive design, I will suggest you to look into bionic car project which includes all relevant aerodynamics designs for cars. Reference : Ted talk by Janine Benyus :
