DUST OF NUMBERS

    


     Draw a straight line. Remove the middle one-third and draw the two segments of line again. In each segment, remove the middle one-third portion again, and draw the four pieces of the line below it. Just go on repeating the process. We finally get the dust of points.

     The first line is having the dimension one. The next segments of lines have a dimension less than 1 because they do not occupy the entire line fully. This pattern has only fractional dimension and hence it is called 'fractal'. 

      Imagine, the length of the first line is marked as in the scale from 0 to 1 in fractions. When the middle portion is cut off, the ends of two segments must have the marking 0 - 1/3 and 2/3 -1. When the two segments are redrawn by applying the same rule, the marking at the ends of the four segments is 0 -1/9, 2/9-1/3, 2/3 - 7/9 and 8/9 - 1. The process can be repeated without end. We get a set of numbers called 'cantor set'. Here we learn that between 0 and 1 there are no integers, but countless fractions and real numbers. That is, even between 0 and 1, the numbers go to infinity. Dust of numbers in the mathematical universe.

      How can we draw cantor set using computers? Say'1' means line and '0' means no line. Rule 1. 1 yields 101 2. 0 yields 000 Using these two simple rules, one can draw cantor's fractal in the digital words as illustrated in the figure. A fractal always has self-similarity. The structure of a branch or a leaf is a replica of the entire tree. Similarly, any portion of this fractal is the replica of the whole pattern. Cantor set is the first and simple fractal and it is the gateway to the amazing fractal world.






                       1
                      1  0  1     
                 101  000   101
101  000   101                 101  000 101    AND ON

Your heart -you do not know

  Size and Location: The human heart is roughly the size of a clenched fist and is located slightly to the left of the center of the chest. Despite its relatively small size, the heart plays a crucial role in pumping blood throughout the entire body. Heartbeat Variability: The heart does not beat at a constant rate. The interval between heartbeats can vary, and this variability is considered a sign of a healthy heart. Factors such as breathing, emotions, and physical activity influence the heartbeat. Electrical Conduction: The heart's contractions are controlled by electrical impulses. The sinoatrial (SA) node, often called the "natural pacemaker," generates electrical signals that regulate the heartbeat and coordinate the pumping of blood. Blood Pumping Capacity: On average, the human heart pumps about 2,000 gallons (or 7,570 liters) of blood each day. Over a lifetime, this amounts to pumping enough blood to fill several Olympic-sized swimming pools. Heart Chambers and V...

THE WORK HORSE "="

    One cannot think of  a mathematical step without 'is equal to ' .  It balances right hand side and left hand side.  It aids simplification and manipulation of a mathematical expression. example: 2(A+B)  = C 2A+2B  = C         2A = C-2B           A = C-2B/ 2   In an electronic calculator,  the pressing of ' = " sign executes an asthmatic expression  or simply calculates.       In computer languages, it plays very important role.                                                                 A = B   When a computer looks at this expression, the value stored in the location named B is just transferred to the storage named A .  After execution both A and B will have the same value an...

How does your smart phone detect motion, steps, rotation, and location?

 How it works-1  An accelerometer in a smartphone is a microelectromechanical system (MEMS) device that measures acceleration and tilt. It works by detecting changes in motion by measuring the vibration or acceleration of the device. The accelerometer consists of a small mass suspended on a spring inside a sealed chamber. When the device is subjected to acceleration, the mass moves relative to the device, causing a change in capacitance that can be measured and processed by the smartphone's hardware. The accelerometer measures acceleration in three dimensions (x, y, and z) and provides data that the smartphone's software can use to determine the device's orientation, detect motion, and track changes in velocity and acceleration. The accelerometer is used for a variety of purposes in a smartphone, including screen rotation, motion tracking for games and fitness apps, and detecting the position of the device for navigation and location services. Additionally, it can be used t...
