LETS REDIFINE THE TIME: TIME MEASURED TRILLION BILLIONTH TIMES MORE ACCURATELY

 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 WORLD'S TALLEST BUILDING: HOW IT IS STANDING ON DESERT IN THE WINDSTORMS😱😱??

  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

coriolis force  the Coriolis force is an inertial or fictitious force that acts on objects that are in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object. In one with anticlockwise (or counterclockwise) rotation, the force acts to the right. Deflection of an object due to the Coriolis force is called the Coriolis effect. The effect of the  Coriolis  force is an apparent deflection of the path of an object that moves within a rotating  coordinate system . The object does not actually deviate from its  path , but it appears to do so because of the motion of the coordinate system.

Reveling Nano big bang

 Revealing nano big bang:  Scientists observe the first milliseconds of crystal formation New study shows how stable materials have unstable beginnings  Date: March 25, 2021 Source: DOE/Lawrence Berkeley National Laboratory Summary: Scientists recruited a world-leading microscope to capture atomic-resolution, high-speed images of gold atoms self-organizing, falling apart, and then reorganizing many times before settling into a stable, ordered crystal. When we grow crystals, atoms first group together into small clusters -- a process called nucleation. But understanding exactly how such atomic ordering emerges from the chaos of randomly moving atoms has long eluded scientists. Classical nucleation theory suggests that crystals form one atom at a time, steadily increasing the level of order. Modern studies have also observed a two-step nucleation process, where a temporary, high-energy structure forms first, which then changes into a stable crystal. But according to an internationa

CLASSICAL MECHANICS PART 1 : CARTESSIAN , CYLINDRICAL, POLAR COORDINATES AND ROTATIONAL FRAME OF REFERANCE

 THE FOLLOWING CONTENT WILL COVER COMPLETE BASIC KNOWLEDGE ABOUT CLASSICAL MECHANICS AND GIVE YOU AN OVERVIEW ABOUT COORDINATE SYSTEMS AND FRAME OF REFERANCE...... Coordinate system In  geometry , a  coordinate system  is a system that uses one or more  numbers , or  coordinates , to uniquely determine the  position  of the  points  or other geometric elements on a  manifold  such as  Euclidean space . The order of the coordinates is significant, and they are sometimes identified by their position in an ordered  tuple  and sometimes by a letter, as in "the  x -coordinate". The coordinates are taken to be  real numbers  in  elementary mathematics , but may be  complex numbers  or elements of a more abstract system such as a  commutative ring . The use of a coordinate system allows problems in geometry to be translated into problems about numbers and  vice versa ; this is the basis of  analytic geometry . Cartesian coordinate system The prototypical example of a coord
