Money is not everything. Really? - Duration: 3:36.

But, in order to get them,

To get 'love', we actually need money.

We need vehicles to visit the ones we love

To get experience and enjoy nature,

we also need vehicles to get there

We need to buy tickets and gears needed

and in the end, it's money.

Then what does 'money is not everything' means?

when everything needs money?

For example, my purpose of life is to be a golf player

To get there, I will need proper golf equipments

I will need a decent golf practice field

and those kind of thing needs money

But, is money my purpose?

Certainly not!

Money only helps me to get to my purpose

to be a golf player

But there are people who placed money as their purpose of life

I like to think 'money' as gasoline

What's the use of a full tank fuel

but you don't know where to go?

Your fuel is not the destination!

Love, experience, happiness

now those are destionations!

and this fuel will help you get there!

What's the use of a nice car and a full gas tank

but you have no journey destination

that's why loving money is vain

you should love the destination, and the journey

not the fuel

That's what 'money is not everything' means.

and this quote is actually meant for people who are greedy about money

they who loved money too much and lost their mind

so they'd calm the heck down

but if lazy people read this, they would get even lazier!

They'd say

"Nah, money is not everything, better slack off and just enjoy the day without having to sweat for work."

Don't complain and bitch around if you feel stuck in life and nowhere near your destination.

Bell Jar Experiment - OLabs - Duration: 1:28.

Bell Jar Experiment

Materials required

A bell jar, battery, vacuum pump, key and connecting wires

Connect the electric bell with battery through a key.

Then connect the vacuum pump to the bell jar.

Insert the key

Then bell started to ring Now switch on the pump, then the vacuum pump

starts to pump the air from the bell jar which is evident from the meter reading of

the pressure gauge. Then the intensity of sound from the electric

bell gradually decreases and when the vacuum pump completely pumps out the air in the bell jar

you can barely hear any sound. Still the hammer continues to strike on the gong.

Hence it is clear that the sound needs a medium to travel.

7 Most Iconic Places to Photograph in the World

Some places are a must to capture through the lens: Like when in Rome, the obvious choice

is the Colosseum and when in Paris, the Eiffel Tower.

But far from these popular destinations, there are many more wonders around the world that

tourists seek out with camera in hand.

here's the list:

1. The Pyramids of Giza, Egypt The wonder of ancient world and one of the

premier attractions of Egypt.

The Pyramids of Giza represent the archetypal pyramid structures of ancient Egyptian civilization.

These pyramids were built as the final resting place for pharaohs, which were kings of divine

right and were seen as living gods.

For some 4,500 years they have been the most wondrous of wonders, in a league of their

own, unchallenged for their sheer audacity, paragons of all design.

2. Venice, Italy Graceful, beautiful, and constantly enchanting,

Venice is also a prime example of the tragic, all-consuming lust for wealth, power, and

sordid ambitions.

Venice is a city in northeastern Italy sited on a group of 118 small islands separated

by canals and linked by bridges.

It is located in the marshy Venetian Lagoon which stretches along the shoreline, between

the mouths of the Po and the Piave Rivers.

The city in its entirety is listed as a World Heritage Site, along with its lagoon.

The lagoon is virtually the same as it was six hundred years ago, making it the most

photographed part of the city.

3. Papua New Guinea In the highlands of Papua New Guinea we come

face to face with the parts of our mind that the modern world has hidden away very well.

Papua New Guinea is one of the most heterogeneous nations in the world.

It is estimated that more than a thousand different cultural groups exist there.

Because of this diversity, many different styles of cultural expression have emerged;

each group has created its own expressive forms in art, dance, weaponry, costumes, singing,

music, architecture and much more.

4. Antarctica The Antarctica is the windiest, coldest and

highest continent, but beyond that, it boasts amazing scenery and tremendous and unique

wildlife.

It's notable for being the only continent with no significant land plant life and no

native land mammals, reptiles, or amphibians.

However its shoreline serves as nesting ground for many species, including penguins.

5. Machu Picchu, Peru One of the most famous and spectacular ruins

in the world, Machu Picchu is located 8,000 ft high in the Andes of Peru.

Most archaeologists believe that it was built as an estate for the Inca emperor Pachacuti.

Often referred to as the "Lost City of the Incas", it is perhaps the most familiar

icon of Inca civilization.

It was built in the classical Inca style, with polished dry-stone walls.

Its three primary structures are the Intihuatana (Hitching post of the Sun), the Temple of

the Sun, and the Room of the Three Windows.

These are located in what is known by archaeologists as the Sacred District of Machu Picchu.

6. Easter Island Easter Island is known as one of the world's

sacred sites.

It is most famous for its enigmatic giant stone busts, Standing in their haunting rows

called moai, created by the early Rapanui people.

A total of 887 monolithic stone statues have been inventoried on the island and in museum

collections so far.

Although often identified as "Easter Island heads", the statues have torsos, most of

them ending at the top of the thighs.

A small number of them are complete, with the figures kneeling on bent knees with their

hands over their stomachs.

Some upright moai have become buried up to their necks by shifting soils.

7. Stonehenge, England Few places invoke timelessness like Stonehenge.

It is a prehistoric monument in Wiltshire, England.

One of the most famous sites in the world, Stonehenge is the remains of a ring of standing

stones set within earthworks.

It is in the middle of the most dense complex of Neolithic and Bronze Age monuments in England,

including several hundred burial mounds.

The absolute knowledge that every year for the past 5,000 years the Earth, the sun, and

Stonehenge have all lined up just so that the rays of light glancing across the face

of Salisbury Plain slip through the upright stones--it sets our sense of cosmic order

on fire.

The rocks hulk there, brawny yet graceful, set in place by crafty people we can scarce

imagine or recall.

Then the moment is gone and we realize that we, too, have been aligned, if only briefly,

with time itself.

Pressure Exerted by a Solid Iron Cuboid on Sand - OLabs - Duration: 3:16.

Pressure Exerted by a Solid Iron Cuboid on Sand

To perform the experiment, we require a tray with dry sand, an iron cuboid and a scale.

The cuboids have three different faces.

Face 1 has length and breadth 10 cm x 6 cm, Face 2 has length and breadth 10 cm x 4 cm

and face 3 has length and breadth 6 cm x 4 cm.

FACE 1 Make sure the sand in the tray is of same

level, if not, make the sand equally level.

Place the cuboid on the sand.

Remove the cuboid from the sand; you can observe a dip in the sand.

Measure the depression using the scale.

The depression is 1.6cm.

Calculate the pressure exerted by the cuboid on sand.

The corresponding area, thrust, pressure and depression are shown in the observation column.

FACE 2 Level the sand in the tray and place the cuboid

on it.

When it is removed, it leaves a dip in the sand.

Measure the depression using a scale.

The depression is 2.4 cm.

Also calculate the pressure exerted by the cuboid on sand.

The corresponding area, thrust, pressure and depression are shown in the observation column

FACE 3 Level the sand in the tray and place the cuboid

on it.

When it is removed, it leaves a dip in the sand.

Measure the depression using a scale.

The depression is 4 cm.

Now, calculate the pressure exerted by the cuboid on sand.

The corresponding area, thrust, pressure and depression are shown in the observation column.

LAST From the observation column shown above we

can understand that the pressure exerted on face 3 is more when compared to the other

faces.

Transformer Testing - Short circuit or Full Load Test of Transformer - Duration: 3:31.

A power transformer is usually employed for the purpose of converting power, at a fixed

frequency, from one voltage to another.

If it is used for converting power from a high voltage to a low voltage, it is called

a step-down transformer.

The conversion efficiency of a power transformer is extremely high and almost all of the input

power is supplied as output power at the secondary winding.

For confirming the specifications and performances of an electrical power transformer it has

to go through Short Circuit Test (Full load test) on Transformer.

In this video we will learn about short circuit test and their procedure.

Objectives of short circuit test.

To conduct standard open circuit tests in order to find the parameters of the equivalent

circuit of a transformer.

Evaluate the regulation and efficiency of the transformer at a given load.

Check the excitation characteristics of the transformer.

Short Circuit Test on Transformer.

The connection diagram for short circuit test on transformer is shown in the figure.

A voltmeter, wattmeter, and an ammeter are connected in High Voltage side of the transformer

as shown.

The voltage at rated frequency is applied to that High Voltage side with the help of

a variac of variable ratio auto transformer.

The low voltage side of the transformer is short circuited.

Now with the help of variac applied voltage is slowly increased until the ammeter gives

reading equal to the rated current of the High Voltage side.

After reaching at rated current of High Voltage side, all three instruments reading (Voltmeter,

Ammeter and Watt-meter readings) are recorded.

The ammeter reading gives the primary equivalent of full load current IL.

As the voltage applied for full load current in short circuit test on transformer is quite

small compared to the rated primary voltage of the transformer, the core losses in transformer

can be taken as negligible here.

Let's say, voltmeter reading is Vsc.

The input power during test is indicated by watt-meter reading.

As the transformer is short circuited, there is no output; hence the input power here consists

of copper losses in transformer.

Since, the applied voltage Vsc is short circuit voltage in the transformer and hence it is

quite small compared to rated voltage, so core loss due to the small applied voltage

can be neglected.

Hence the wattmeter reading can be taken as equal to copper losses in transformer.

Let us consider wattmeter reading is Psc.

. Where Re is equivalent resistance of transformer.

If, Ze is equivalent impedance of transformer.

.

Therefore, if equivalent reactance of transformer is Xe .

.

These values are referred to the HV side of transformer as because the test is conduced

on High Voltage side of transformer.

These values could easily be referred to LV side by dividing these values with square

of transformation ratio.

Therefore it is seen that the short circuit test on transformer is used to determine copper

loss in transformer at full load and parameters of approximate equivalent circuit of transformer.

WHAT IS A THIRD WHEEL (ONE MINUTE ENGLISH L3) - Duration: 1:12.

Hey guys welcome to this week's one minute English lesson.

Today we will be looking at the saying 'A Third Wheel'.

This is somebody who has an impact on a couple's relationship or a couple's plans.

For example 'A Third Wheel' might get invited out of pity to a couple's plans to go the

cinema and everybody feels a little uncomfortable whilst they are there.

So you might hear 'The Third Wheel' say stuff like I feel like a third wheel or they might

say I would come to the cinema with you but I don't want to be a third wheel.

This saying actually comes from the saying a fifth wheel and this was said simply when

a vehicle would have an extra wheel or a spare wheel being the fifth wheel and that's where

we get the idea of a third wheel being a sort of extra or a spare part or a spare person

in the couple.
