IM... POSSIBLE WORDS

BLACK LIGHT
Can you see things with invisible light? Yes, you can.. The ultraviolet rays are invisible. When it is shone on an object quoted with florescent chemicals, they emit back light and appear bright. For example, the security thread of a dollar bill glows green under black light, a safe guard against counterfeiting . So light can be invisible and black.

SOLID GAS OR DRY ICE.
Under high pressure and cold temperature, carbon-di-oxide gas directly becomes solid called dry ice. It is widely used in fire extinguishers which emit them as white powder.

DYNAMIC EQUILIBRIUM:
How can a thing be at rest and moving at the same time? Imagine a queue is moving through a room. At a time, the room can accommodate only 10 persons. So the room always have 10 people, yet the people keep moving. This is dynamic equilibrium.

HOT ICE
Using vinegar and baking soda, one can make boiling ice like form to attract kids.

LIVING DEAD:
A dead virus can at any time come to life under suitable conditions. A lifeless seed can give birth to living plant also under suitable conditions.

WATER BLADE
A highly pressurized water jet can cut a metal. Machines are available to produce such a jet of water.

LIGHT GUN
A concentrated and highly intense light is called laser. The laser can act like a bullet , knife and an arrow.

Science and poem give birth to new and strange combination of words.

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...
