Fire was the first discovery and wheel was the first invention. Since that time, we have traveled far. Science has taken us to territories we could not have envisaged some centuries ago. 20th century was when science really came into its own. It produced magic realism for us. Half of our present day inventions were inconceivable a century ago.
Science had brought great laurels in every field but the one place where it has really shone is technology. Today, we have access to some of the most unbelievable technical inventions. A few centuries ago, a mastermind called Leonardo da Vinci made the first blue-print for an aero plane. Today, even the economy class, domestic seaters have become pass. It is time for the new avatars. Who would have thought that we could fly miles above the ground on a machine that is streamlined to fight air resistance?
A few days ago, NASA launched a Space Shuttle called Discovery. It is supposed to use truss bands and solar wings to propose a new means of solar reception. Imagine, a tangible metallic object run on hydrogen fuel, stationary in space, thousand miles away, bringing us news, data and newer means of improvement.
Its not only about the aerial endeavors. Vehicles which run terrestrially are packed with newer inventions by the day. The Lamborghini, Masseratti, and Maybachs have technology written all over them. These are the mechanical devices which have made us a Nano-race.
We have rewritten the rules for acoustics and the auditoriums and theater studios are a testimony to this. We have come into a digital age. Computers have given way to laptops and then to notebooks and palmtops. Picture-tube televisions have metamorphosed into LCDs and Plasma. They offer High Definition Imaging which again is a vanguard formula.
Landlines took a leap with mobiles. The mobiles have converted into a complete island of entertainment and communication.
Internet has brought the impossible within means. It has made online education possible through its familiarized territory. A teacher in Spain can teach a student in Nigeria with the help of Elluminate whiteboards and Voice Chat modules.
Heat Sensor technology and technical receptors have advanced to such an extent that we can make refractors which respond to heat and temperature variations a hundred miles away.
Mathematicians such as John Nash; scientists like Albert Einstein and Isaac Newton, and many others have turned the tables of the world. Theory of Relativity and Gravitational Constant has been the cornerstone of many scientific inventions.
Science has really beautified life. Today, you can visit your ailing relative on the other side of the globe within a day. You can look at an award ceremony held in London, sitting in a nook of Algeria. You can convert thousand and thousand pages of data into a pin size chip and still have plenty of space left.
You cannot come back from the dead but thats probably the only thing you cannot do. The borders of time and space are certainly shrinking.
