FLAVOURS OF NUMBERS

100, 1100100, 64,25

all represents the number hundred in different numerical languages.

We count the minutes as 1,2,3...60 and mark it as one hour. Again we start counting the minutes from 1. So the minutes and seconds are having the base of 60 or radix 60. We count the inches 1,2,3 ....12 and mark it as 1 foot. It is having base 12.

In our day today life, we use numbers of base 10. (tenary numbers or decimal numbers)
We are used to this 10 number system and very comfortable with it. But a number system can have any base.

Unary numbers uses only one digits.

1-----l
2-----ll
3-----lll
4-----llll
You know using this unary numbers is highly difficult.

Next we have binary numbers using only two digits.
0,1,10,11,100
These numbers are widely used in all digital devices. the signal like voltage and current can either represent 0 or 1 and not anything in between. Hence the digital data cannot be corrupted and hence we gaga over digital devices.

Next we take up the numbers of radix 16 called hexadecimal numbers.

In this system we use alphabets also. As you can see, it is very compact. It can be represented by 4 binary digits. Hence hex. numbers are preferred notations in representing colours in a digital display.
Number system having bases 8 and 36 are also popular.

Tenary 10 means 10 (usual numbers)
binary 10 means 2
hex. 10 means 16.
Like words the numbers also have different shades and meanings depending on the context.

Devise your own number system to code the playing cards.

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...
