Bike Riding Tips and Tricks

Now a days the youth are more passionate about their bikes and adventurous rides with it. The bikes and stunts are really a guy thing which drives the riders to crazy fun like nothing else. But they don’t realise the risk underneath their stunts until they are once experienced for. The following tips will be quite useful for the begginers who are going to be a good riders in future. With all senses a rider has to control the following:
 • Brake 
• Clutch 
• Acclerator 
• Signals lights 
• Sharp turns 
• 150 degree view ahead 
With perfection in these the ride will be under control and happy....but lacking in any thing of above may result in severe disasters.. Common mistakes by Riders: 
• Applying brakes while crossing sharp turns which result in skidding of vehicle. 
• Making the vehicle to run down street with engine off. 
• Not maintaining the center of mass of (bike+rider) jointly.
 • Careless ride by consuming alcohol.,etc.
If you can’t turn a crossing sharply then just apply brakes ahead and then slowly make the turn rather than skidding over the road. Riding the bike downwards with engine off makes the rider to loose control over the vehicle.Remember that an engine in On state works greatly than the engine in Off state.The person should understand his bike well enough to maintaine the center of gravity always aligned in correct manner.The following fig shows the difference
By carefull pressuring up your weight on the foot rest will do a great job under sharp turns. Always drive on the right side of the road and for some countries like India you should align yourself on the left side of the road as per the traffic signs and signals.Use hand signals when ever and where ever necessary.

The Largest and the Smallest

The size of the universe for now is 1,000,000,000,000,000,000,000,000 meters (1 Yottameter) i.e diameter of universe at present,however it expands above this in its own manner and inertia....

The size of sub-sub atomic particle NUTRINO is 0.000000000000000000000001 meter (1 Yoctometer) i.e diameter of nutrino....Planks length is 10^-35, any length less than this has no physical meaning......

Define a second of time

The second has been defined to be
the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.
i.e. the time taken by the electron in cesium atom to transfer from one energy band to the other. That's Amazing right.

Most of us don't know what exactly one second of time period refers to and how it is defined here it is.

Now the question lies on how exactly our watches calculate this second. Is it close enough or is it accurate to the nth decimal of a second. But again time is relative.
