HISTORY CREATED BY REDEFINING THE TIME TRILLION BILLIONTH TIMES MORE ACCURATE..... YES.... YES..... YOU READ IT CORRECTLY WE HUMANS ARE NOW AT A STAGE TO REDEFINE THE TIME MORE PRECISELY , ALMOST 1000 TIMES MORE ACCURATE THAN PREVIOUS. LETS NOW HAVE A LOOK AT HOW DO SCIENTISTS ACHIEVED THIS MILESTONE: SCIENTIST OF NIST COMPARED THE 3 ATOMIC CLOCKS (YTTERBIUM , STRONTIUM , ALUMINIUM & MAGNESSIUM ) BY CONNECTING THEM VIAOPTICAL FIBRES. SCIENTISTS HAVE COMPARED THESE THREE CLOCKS UPTO AN ACCURACY OF100 TIMES MORE THAN RECENTLY IN-USE CESIUM CLOCKS. THE SPECIALITY IN THE EXPERIMENT WAS THAT THE UNCERTAINTY IN MEASURING THE FREQUENCY RATIO WAS ONLY 0.000000000000000008 CONCLUSION & BENEFITS OF RESEARCH :- THIS RESEARCH WILL NOW BE HELPFUL IN DEVELOPING ATOMIC CLOCKS WITH MORE ACCURACY IN FUTURE AND INTERNATIONAL TIME KEEPING.
PHYSICS BEHIND THE WORLD'S TALLEST BUILDING........ BURJ KHALIFA WE ALL KNOW THAT BURJ KHALIFA IS THE TALLEST SKYSCRAPPER IN THE WORLD TILL NOW ......... BUT HOW MANY OF US KNOW THE PHYSICS BEHIND THE PHYSICS BEHIND THE WORLD'S TALLEST BUILDING........ LETS HAVE A LOOK TOWARDS IT:- AS WE ALL KNOW THAT BURJ KHALIFA IS LOCATED IN DUBAI WHICH IS A DESERT AND WE HUMANS CAN NOT EVEN STAND ON DESERT SOIL AND OUR FEET GETS SINK INTO THE SOIL THEN HOW BURJ KHALIFA IS STANDING ON DESRT SOIL WITH ITS 😱500,000 TONNES😱 OF WEIGHT LETS FIND OUT...... HERE IS YOUR ANSWER..... THE ANSWER IS 😱 FRICTIONAL FORCE 😱 YES...... BURJ KHALIFA IS ONLY STANDING ON THE DESRT SOIL DUE TO FRICTION BETWEEN SOIL AND THE PILES(192 PILES BURIED >50 METRES IN SOIL) HERE IS THE VIDEO DEMONSTRATION OF HOW STRONG FRICTIONAL FORCE IS NOW WE WILL DISCUSS ABOUT THE NON-CUBOIDAL SHAPE OF B
