Where did we come from ? Are we really stardust ?

We are in 21st century, with such technological advancements that we can go back in time to the point of creation, when everything started. We are able to understand how everything works around us. Although we can't prevent natural disasters, we can predict them and take necessary precautions. Today we have built skyscrapers to live like kings, we live in luxury houses with technology all around us to make our life simple and easy. We have built cars, ships, underwater-ships and air-planes to satisfy our needs, use wireless cell phones to stay connected with others whenever we want & above all the internet to know about anything anytime. Even we have invaded the space with highly advanced spacecrafts.

But a good designer always know that to transform a good design into a better reality, you need the best building block. Afters thousands of years of evolution man has finally been able to understood the secrets behind the magic material and was able to use it efficiently. Just look around you and you will find it almost everywhere, one of the basic building block of 21st century, steel. Steel is a primary mixture of iron and carbon (carbon content 0.2% and 2.1% by weight depending on the grade) but, the desired physical and mechanical properties of steel can be achieved by adding various metals like Silicon, titanium, vanadium, molybdenum, chromium, manganese etc. That's why steel is suitable for various applications like, building a small needle to a massive and complected mega machines but, it's not the only reason steel is so popular. It is popular because it's an iron alloy and iron is one of the most abundant element of planet Earth. It forms much of earth's outer and inner core.


But ever wondered where does the iron comes from?
