How to choose engineering stream and college?

It you are aspiring an engineering career and a course then this time or the days after the 12th exam or the 12th grade college exam should be the most stressful and the most vulnerable time in your life. I have been through the same and I would like to share my experience with all, so that the people in need can benefit.

What should be your criteria to choose the stream?

Let me tell you something there are hundreds of steam and there are hundres of colleges that offer the same course. The best criteria to choose the steam should be your choice of career. Ask your self what kind of career do you want? Do you want a table and an office job? or do you want a field job? You should not choose the steam on the steam on the basis of what your friends are opting or what your parents are telling ?

If you have chosen the career you want to perceive then choose the appropriate strem that will land you that job. And try and choose the stream that is having a large scope of application as it will make it easy to choose for a wide variety of jobs and careers. 

Try and choose the stream that is core and not specific. For example you want a job as a research engineer in a motor or an automation company then your chances of landing a job is more when you have a mechanical degree than a automobile degree.

What basis the colleges should be chosen?

Many students choose the colleges on the basis of the fame of the institution. Let me tell you in the end of the day the only thing that will matter is how wonderful you are in what you do. It is totally useless to choose the colleges on the basis of the palcements that are offered as it is a changing trend and it may be good in one year and worst in the other year.

If you choose the colleges on the basis of palcements it is totally futile as there is no gurantee that you will get placed. And the jobs that are offered are poor with poor salary so do not fall under this impression

There are some people who go to institutions which have a good name but are charging heavy fees, this is waste of money and waste of your time. They will say that inorder to go to these institutions you need to write an exam and you need to clear it. But at some time after the admission processes are completed there will still be seats that will be empty and they will call any one who is willing to pay the fees.

This website will give you a good idea of what I am talking about.

At this point in your life you may be feeling that you are worth nothing as all the people are defeating you in the admission process but believe me once you get into an engineering college you will find that all the croud is filled with dumb people the whole world has to offer.

Even if you are getting a lower end colleges, the chances and the opportunities that you will have will be amazing as you will be the only handful of smart people in the whole college.
Best of luck.

3D printing the next manufacturing technology?

The 3D printing or the 3 Dimensional way of printing. These printing is picking up like wild fire in the manufacturing industry and in small scale businesses. This type of printing is basically getting the desired product printed. In the normal paper printer or the photocopier the printed material will come out of the copy machine. In this printing the material needs to be supplied to the printer of which the article needs to be printed the printer will print the desired object and will be in the ready to use condition.
 All the pictures used in this blog do not belong to me. And I do not claim on its ownership

This style of manufacturing the object is called as additive manufacturing, because we do not have the material in place before and we remove the material to make our object.

But here the material is added to the object to make the object so there is no waste of material, and some unbelieveable objects and shapes can be made without much effort

I attended one of the workshops that teach how to make our own object and make it compatebale with the printer program, and I can gurantee you it is pretty darn simple.

This is what we did in the old era of manufacturing,All the pictures used in this blog do not belong to me. And I do not claim on its ownership
we removed the metal or the material to make it look the way we want. The brilliant example is this CNC machine which is designed by the titans Eagle company.
 This not only leads to loss of good quality metal and also limits the shape capabilities of the object design
 Like the hollow cavity in the eagle is not possible but this is possible in the 3D printing method. Making it light and more eco friendly

 Look at this very intricate design in the elephant structure. this is just not possible by the molding methods that we have, because to remove metal of in this case plastic in such a details is just impossible.

With just a computer and a 3d printer hooked up you can get this stuf in your hand in basically 2hrs.

It is even less costly. it is just plastic. You see this wonderful object
To make this is just impossible . To make it out of one piece is also impossible.

With every good use there is a bad use
the people will use it for producing guns and weapons
think about the situation when the guns are in the hands of the person who should not be having one in there hands
This is 3D printed gun which should not be in the hands of people without the knowledge of the authorities

Just any one can cause the damage. So special restrictions are there in some countries over the use of the 3D printers

Have a look at this funny video of Elders react to this new technology.

Carbon Nanotubes - The New Fad

Carbon nano tubes are considered to be the next advancement in the field of science, after the invention of computer and transister. 'Nano' in the name implies that the structure is surely in the range of 10^-9 meter.
to understand how small it is take an example.

If you consider a small marble ball is one nano meter , then the diameter of the earth would be one meter.

HOW WERE THEY DISCOVERD?

In 1952 L. V. Radushkevich and V. M. Lukyanovich published clear images of 50 nanometer diameter tubes made of carbon in the Soviet Journal of Physical Chemistry. This discovery was largely unnoticed, as the article was published in Russian, and Western scientists' access to Soviet press was limited during the Cold War. But officially the discovery of the carbon nanotubes is considered to be in the year 1991 by a Japanese Scientist Sumio Iijima,

Here again we see the prejudice the west had towards the non western cultures and sciences   

                                            

WHAT ARE CARBON NANOTUBES?

Carbon nanotubes are nothing but a cylinder made up of patches of hexagon shaped carbon structures
Just like shown in the picture.
Well, looking at the structure it seems so impossible to create the tube in such an orderly manner.

Don't worry if you have the right equipment and the necessary temperature you can make these structures even in your back yard or best your kitchen.All the pictures used in this blog do not belong to me. And I do not claim on its ownership

 This video show exactly how easy I mean when I say it is easy to create such nano stuff, contrary to the popular belief that nano technology is something sophisticated.

SO WHY IS EVERYBODY GOING CRAZY OVER IT?

Well the answer is simple Because of its properties: This material has properties which would make even the god of metal, or for a better comparison even Thor jealous.

Carbon nanotubes have 50 times more tensile  strength than steel and 5 times the Young's modulus

The theme photo of the blog is the direct consequence of these properties. Maths shows that carbon nanotubes can be used to make space lifts that could stretch up to the altitude of the orbiting satellites.

 This image is of the steel after taking a huge load leading to a fracture, So to imagine the carbon nanotube in its place would take 5 times the load and still not fracture. It is amazing.

If you are looking for a research topic then this is the best for you as it is the booming field and its application is unimaginable.
