NO LIFE WITHOUT UPS AND DOWNS

     


      A river flows from mountains to seashore - from top to bottom.  If the surface is even, it cannot flow, it will only stagnate.

     Air flows from high pressure to low; heat flows from high temperature to low; current flow from  high voltage to low.  For an engine to work, heat source at high temperature and a sink at low temperature to receive heat must be available.

      In all automobiles, engine is the source and environment is the sink.  That is why, in winter season, some two-wheelers are difficult to start.  Because the engine should be heated up before working.

     Our body is a kind of engine.  It is slightly at higher temperature than the surroundings.No life in a cold body.

      In the solar system, sun is the unique source at very high temperature and the rest of the planets in the system is the sink.  Sun keeps solar system working and hence the earth ebbs with life(photosynthesis, rain, etc).

    So we learnt that, ups(source) and downs (sink) are essential for the life to go on. Hence, in our day-today life also, ups[ gain, success, promotion, health],  downs[loss, failure, demotion, ill-health] should be endured to keep the life in progress.

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...
