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.

AWESOME!!! 7 Most Iconic Places to Photograph in the World - 7 NEWS - Duration: 5:44.
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.
