PRESIDENT'S BRIEF CASE AND THE ATOM BOMB

     


     US president's aide always carries a bridf case using which he can annihilate the world at any moment.  Yes, it is a black leather suitcase weighing 45 pounds and it is always within the reach of the US president.  It is nicknamed "nuclear foot ball".
     On the day, the US president sworn in, he receives the world's most powerful ciphers(encrypted text) called the gold codes, they are printed on a plastic card similar to a credit card that is known as the BISCUIT.  They allow the president to identify him or herself as the authorized user of the foot ball.  President's carry the biscuit on their person day and night.    The nuclear football is carried by one of a series of rotating military aides who are always with the president, travelling in the same vehicle, taking the same elevator, and staying on the same floor of a hotel.  These aides have undergone extensive psychological testing.
     The foot ball is a communications device for contacting the joint chief of staff and the national military command center.  In the event of nuclear war, the president would decide the target and dimensions of the attack.  Also, the vice president has a duplicate of the Nuclear foot ball.
    Triggering a nuclear holocaust is as easy as tweeting, only if a president wishes.  OK what is Nuclear bomb?  Einstein said matter(mass) and energy is one and the same.  Both can be inter-converted according to the famous formula E= mc^2.  When a big atom like Uranium is broken (fission) by bombarding neutrons, some mass is lost which converted into energy.  In a fission process, a few more neutrons are also released.  These neutrons cause further fission and the chain reaction continues uncontrollably resulting in the explosion.  During the explosion, tons of energy is released in the shape of heat, light, radiation causing very high temperature and pressure.  In such an environment, no life can survive.
    Today, many countries have missiles carrying nuclear war heads.  They are mainly used as 'deterrent' and not in the actual war.
     Hiroshima and Nagasaki is enough for the mankind.  Now, Nuclear energy is used for the peace purpose.  When chain reaction is controlled, Nuclear bomb becomes Nuclear reactor in which, we can safely extract electrical energy.
     We strongly hopes and wishes that US president never gets the opportunity to use the "foot ball" and the "biscuit".

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...
