MATHEMATICS OF LOVE

How some sites like "okcupid" find your 'match' or 'would be', mathematically. We will see that algorithm in simple language.
The site or the app asks a number of simple questions. One can choose and answer the questions. The more you answer, the more likely you will get a match. While answering, three things should be done. 1. Attach some importance to the question. 2. Give what answer you expect for the question from other person. 3. Answer the question yourself. Let us see an example.

SCORES FOR IMPORTANCE
Irreverent - 0
A little important - 1
Some what important - 10
Very important - 50
Mandatory - 250

Let us take 2 questions
1. Does my height matter for you?
2. Do you earn a five figure salary?
Let us assume that 'you' and your would be partner 'x' answer these questions.

Now, we have to view the scores in your point of view and in X's point of view.

IN YOUR EYES
For the first question, X scored 50/50. Since X have given the answer you want and you have attached very important to it

For the second question X scored 0/1 , since the answer is not expected one. Now combining both the scores.
50+0/50+1 =50/51 = 58%
Hence X scored 98% in your angle.

IN X'S EYES
For first question, you scored 0/1
(not expected answer, little important)
For second question, your score 10/10(expected answer, somewhat important) combining the points.
10+0/10+1 = 91%
Your score is 91% in X's eyes.
The final step of the algorithm is to find 'match percentage'. Here, we are going to take geometric mean of two persons' scores. So, multiply two scores and take square root.
square root of( .98*.91) = .94=94%
94% is the match percentage for you and X. A good percentage.
Suppose, three questions are answered, we have to take cube root. If n questions are answered, we should go for nth root. The higher 'n' gives, high match percentage. (please work out and find yourself). The higher your match percentage with a person, the higher up your profile will appear in their results and their profile in yours. Hence, the more you answer, the wider your pool of questions, your chance of finding the 'date' increases. Good luck.

FOOT NOTE: This article does not favour or disfavour the algorithm. But only appreciates the math element in it.

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...
