ANTIKYTHERA MECHANISM

I came to know about this mechanism only when our tutor taking "Signals and systems" mentioned on it. It's mystery remained hidden till the recent time.Because till now the scientists and the mathematicians could not understand its mechanical working and resolve it. But now it is unleashed. Let me tell something on this mechanism from Wikipedia.

 The mechanism is the oldest known complex scientific calculator.The Antikythera mechanism is an ancient mechanical computer designed to calculate astronomical positions.It is considered as the world's first analog Computer. Its time of construction is now estimated between 150 and 100 BC upon theories of astronomy and mathematics developed by Greek astronomers.The degree of mechanical sophistication is comparable to a 19th century Swiss clock.
                  
Professor Michael Edmunds of  who led the most recent study of the mechanism said: "This device is just extraordinary, the only thing of its kind. The design is beautiful, the astronomy is exactly right. The way the mechanics are designed just makes your jaw drop. Whoever has done this has done it extremely carefully ... in terms of historic and scarcity value, I have to regard this mechanism as being more valuable than the Mona Lisa."

Let us see what it is... from this videos. It was recreated with Lego Mind-storms. It is also shown here.

      

Theo Jansen's Mechanism

Theo Jansen  is a Dutch artist. He builds large works which resemble skeletons of animals that are able to walk using the wind on the beaches of the Netherlands. His animated works are a fusion of art and engineering; in a car company television commercial Jansen says: "The walls between art and engineering exist only in our minds." He strives at equipping his creations with their own intelligence to manage avoiding obstacles, by changing their course when one is detected, such as the sea itself.

Mileage Tips For Your Vehicle

This gives you certain mileage tips ,you can try over your vehicle that might lead to  better fuel efficiency. These are tips that I tested on my vehicle.

Tip 1
Change the engine oil after fixed periods. Don't let your engine oil to be  black cloudy color. I am talking this in the case of two wheelers. For other vehicles, always go for some better oils and the ones that are recommended as per engine configurations.One of the main factor that affects mileage  is the quality of oil that the engine consumes .

Tip 2
Don’t twist the accelerator throttle at a sudden, let the bike gain velocity by applying average acceleration.  never engage brakes at sudden. Ride at uniform speeds!

Tip 3
Make sure you ride your vehicle when its engine is warm. A cold engine consumes more fuel than a warm one.

Tip 4
Tyres  play a major role in balancing fuel consumption . Maintain tyre pressure correctly when ever you are at petrol pump (fuel filling station ).

Tip 5
Try using Kicker rather than Self starting Mechanism (2 Wheelers)
