experience with Xiaomi mi band 5

  Mi band 5 

I bought my mi band global version in October 2020 for around 50$, In corona Pandemic, I wanted to stay healthy and fit. so those days I started to work out with some Exercise,  Yoga, and Meditation sessions, when I take a long run normally the band show 135-150 BPM," BPM "means heart beats per minute at the normal state I have 70-76 BPM.

and it is also water resistant smartwatch it has nearly 20 days of battery life. we can swim Go to the gym bath while we wearing It, 

But I Observe an issue, when I ride my bike it is also counting Steps so at the end of the day sometimes I Got a considerable step count.

Anapanasati

At first, I started " Anapanasathi " which Focus On Breath. I did that meditation daily bases for around 20-30 minutes. 

when I started BPM was around 70-80 But at the end of the session, my BPM Became around 60.

I followed this routine for 6 months,

Some days I feel deep Focus, but some days I feel more disturbed by my Inner thoughts. after some time I recorded the lowest BPM Which is 53BPM.

Guided Body Scan

The body scan is also a good practice we just need to plug in the earphones and listen to it with deep focus.

I am still following for guided meditation "The Mindful Movement  " YouTube channel It will also help you for Success Your Inner Journey

 

In the Body scan meditation, I have recorded the same BPM Values, 

but some days I have tried that meditation while lying down In bed most days I have fallen down to sleep

But the Mi band measures exactly my meditation time and sleep time separately.

I Invite you to Try this experience 

 Archimedes principal part 1

1. Upthrust

up thrust is a force that generates by a body going through air or a liquid.

simply we can explain "The Force" as a push/pull.

if someone tries to push or pull he also creates a force. 

2. so what happens from an upthrust?

while we are in a swimming pool or a Sea, Lake.. we can jump more easily because the water generates a force, water helps us to jump vertically that's the effect of up thrust. so liquids help us to float by giving us up thrust,

3. so why are we still drowning when we bathe a Swimming Pool?

normally our earth tries to pull us to the ground we call it Gravity. that's why we are diving a pool.

But while we are drowning in the pool up thrust trying to push us opposite direction. but most of the times it is not sufficient to keep us float. 

4.Are there any places that up thrust can win and make us float?

yeah, there are some places in the world,

                                        ex-dead sea 

 it has sufficient up thrust to float a man easily in there you can read books while you are reading books. you should thank for up thrust.

5.Is up thrust works on air?

 yes of course it is. normally air Planes,Helicopters even birds uses up thrust for there flying.

actually these aircraft birds Knows exactly how to use the up thrust, that's the reason for their flying ability. and also  birds have evolved for controlling the up thrust.

6.so how Archimedes connects with upthrust

Archimedes is the mathematician who discovered a principal about upthrust

 this is the principal of archimedes

According to Boundless, 

"the Archimedes principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid that is displaced by that object. "

lets sort this out

when we put a stone into the water, The stone owns his volume while in the water so the water level will raise 

but this is the thing, if we measure this raising water volume and it's mass ,and convert it into it's weight then we have a number,

this number represents the up thrust acting on the stone.

so how do we convert that mass into the weight,we can use this simple formula

weight=mass* acceleration of gravity

if the fluid withdraw/raised 2kg water then the up thrst action on the body is 20N   

 weight=2kg*10m/s2

            =20N

see you in the next blog.

 Archimedes principal part 2 with some calculations.

 Directed Numbers

 What are Directed Numbers?

we can count things like stones,dogs,trees..etc ,for counting these objects we use natural numbers 1,2,3,4,5.... but sometimes we want to count numbers with a direction 

Ex-

 lets imagine about a River which remain water constant for a long period, But One day it's water level dropped so we need to express this situation with numbers. in here we can apply directed numbers. But how?          

   If water lavel drop we can call it as a negative Value. like (-1.5)meters

   When water level Rise We can Represent it as a positive value like (+2) meters 

So when we have two direction Value change we can use Directed Numbers

Ex-Temperature 

      water Level

      financial Situations

      for a Motion of an Object

examples for Directed Numbers(Integers)

+1,+2,+5,+6,+7.. -1,-2,-3....

Def for Directed Numbers
"All the numbers that are written with a positive or negative sign to indicate not only their magnitude but also one of two directions which are opposite to each other are defined as directed numbers."

How to Identify the sign of a Directed Number

when someone didn't mention about sign of a number we consider it as a positive number.

sign is always placed in left side of the number

ex- -4,+3,-7.5

     +3-4+12  (in this expression -sign for 4 and               7.5,+sign for 3 )

Addition and subtraction of Directed Numbers

rule 1

when we have Addition or subtration 

If

signs are eqal add the numbers without considering their signs and put answer. the sign of the answer should remain same.

                   ex- (1)  +13+2

                                 = +15

                         (2)  -10-5

                                = -15

                         (3)  12+8

                                = +20

rule 2

when we have Addition or subtration 

If

signs are not  eqal subtract the numbers without considering their signs and put answer.the sign of the answer should be the sign of Largest number

                   ex- (1)  +13-2

                                 = +11(largest number is 13 it's                                             sign is +)

                         (2)  -10+5(largest number is 10 it's                                             sign is -)

                                  = -5

                         (3)  12-8(largest number is 12 it's                                             sign is +)

                                = +4
