: A Barometer is used to measure the atmospheric pressure, which is
more at earth's level and proportionately goes down as the height
increases. Or the pressure is inversely proportional to the
height. Hence a Barometer could be used
to measure the height, by finding the pressure difference at the top
of a building relative to the atmospheric pressure at the Earth level.
Pressure at Sea level is 1,013 Millibars.
Since more than half of the atmosphere's molecules are located below
an altitude of 5.5 Km, atmospheric pressure decreases roughly by 50%
(to around 500 millibars) within the lowest 5.5 km. Above 5.5 Km,
the pressure continues to decrease, but at an increasingly slower
rate (to about 1 millibars at 50 Km).

Barometer" first introduced in 1860. The actual length of the
barometer was about 3.5 feet. Photo courtesy of "Saunders and
Cooke". Now, packet size Digital Barometers are in common use.
During early 1900s, One of the prime
question in the Physics degree examination at the University
of Copenhagen (Denmark) was "Describe how to determine the height of
a skyscraper with a barometer ?"
One student answered : "You tie a long piece of string to
the neck of the barometer, then lower the barometer from the roof of
the skyscraper to the ground. The length of the string plus the
length of the barometer will be equal to the height of the building." He
provided such logically correct, and Un-disputably supported answers
for many such Physics degree examination questions
These highly original answers, incensed
the examiner and the student was failed in Physics. The
student appealed on the grounds that his answer was un-disputably
correct. Also, he argued that the question paper was given only
to provide the correct answer, and not any particular answer to suit
the likings of any examiner. In addition, he said "The
answer provides an Un-disputed support to the Concept of Measuring
Height, irrespective of the instrument in question, like Ammeter,
Galvanometer, Hodometer, Hygrometer, Lactometer, Odometer,
Voltmeter.... name any...".
The university decided to appointed an independent arbitrator to decide
the case. The arbitrator judged that the answer was indeed correct, but
it does not reflect the basic and expected
familiarity of the student with a degree level physics. It was
decided to call the student in, and allow him 10 minutes to
provide a verbal answer to the prime question, which could
show at least a minimal familiarity with the basic principles of
For 5 minutes the student sat in silence with
his forehead creased in thoughts. The arbitrator reminded him that time
was running out, to which the student replied that he had
several extremely relevant answers, but he couldn't
make up his mind which to use. He was served with the traditional
Danish Punch Fruitee (See Recipe below),
to wet, smoothen and open up his throat, as well as advised to
hurry up. The student then quickly and energetically replied
Firstly, If the skyscraper has an outside emergency staircase, it
would be easier to walk up, and mark off the height of the
skyscraper in barometer lengths, then add them up.
the sun is shining you could measure the height of the barometer,
then set it on end and measure the length of its shadow. Then you
measure the length of the skyscraper's shadow, and thereafter it
is a simple matter of proportional arithmetic to work out the
height of the skyscraper.
you could take the barometer up to the roof of the skyscraper,
drop it over the edge, and measure the time "t" it takes to reach the ground. The height of the building
can then be worked out from the formula H = 1/2(g
X t2) . But bad luck is on the
barometer. (g is the gravitational acceleration and "t" is the
time taken to fall to the ground).
But if you wanted to be highly scientific
about it, you could tie a short piece of string to the barometer
and swing it like a pendulum, first at ground level and then on
the roof of the skyscraper. The height L is worked out by the
difference in the gravitational restoring force
= 2 π (L / g)˝
the gravitational constant).
If you merely wanted to be
boring and orthodox about
it, of course, you could use the barometer to measure the air
pressure on the roof of the skyscraper and on the ground, and
convert the difference in millibars (unit to measure the pressure)
into feet, to give the height of the building.
But since we are constantly being exhorted
to exercise the independence of mind and apply scientific methods,
undoubtedly the best way would be to knock a locked
janitor's door and say to him "If you would like a nice new
barometer, I will give you this one, but if you tell me the
height of this skyscraper !!".
may be a worth while idea to find the museum room of the
building. Look for the original Site map or the Engineer's
drawings and the Architectural design maps. It will give the exact
height, and serve as a sure source for the accurate height of the
building. As a gesture and exhibition of your philanthropic
attitude, you can present the Barometer to the museum
collection, in return to the information and reference service you
arbitrator inferred that the student has given the correct
answer (5). Two answers involving formulae are acceptable to
physical science (3 & 4). Two logically supporting answers (1 &
2) are layman's answers. However two answers were considered not acceptable to the area
of physical science (6 & 7).

A Million $ Question !!
The student was Niels Henrik David Bohr, the first person from Denmark to win the Nobel prize for Physics
in 1922. (Subsequently, Ange Niels Bohr, the 4th of his 6 sons, won
a Nobel prize in Physics in 1975, for his geometry of atomic

Bohr's Atomic Model
He received the Nobel Prize for this work in 1922,
for his services in the investigation
of the structure of atoms
and of the radiation emanating from them.
RED = Proton
= Electron (▬)
Niels Bohr was born and educated in
Copenhagen, Denmark. (Denmark is a monarchy and a modern democracy
with Copenhagen as the capital). He lived, worked, and died there.
But his contribution to science and history was of use worldwide. His professional
work and personal convictions were part of the larger stories of the
century. At the University of Copenhagen, he studied physics and
played soccer (though not as well as his brother, who helped the
1908 Danish soccer team to win an Olympic silver medal). After
receiving his doctorate in 1911, Bohr travelled to England on a study
grant and worked under J.J. Thomson, who had discovered the electron
15 years earlier. Bohr began to work on the problem of the atom's
structure. Ernest Rutherford had then suggested the atom had a
miniature, dense nucleus surrounded by a cloud of nearly weightless
electrons. However, There were a few problems with the model. For
example, according to classical physics, the electrons are orbiting the
nucleus, should lose energy until they spiral down into the center,
collapsing the atom. Bohr proposed adding to the model the new idea
of quanta put forth by Max Planck in 1901, as the electrons
existed at set levels of energy, or at fixed distances from the
nucleus. If the atom absorbs energy, the electron jumps to a level
further from the nucleus; if it is radiated energy, it fell to a
level closer to the nucleus. His model was a big leap forward
in making theory fit for experimental evidence, that other
physicists had found over the years. A few inaccuracies remained to
be ironed out by others over the next few years, but his essential
idea was proved correct. He received the Nobel Prize in Physics for
this work in 1922, and it's what he is most famous for. But he was
only 37 at the time, and he didn't stop there. Among other things,
he put forth the theory of the nucleus as a liquid drop, and the
idea of "complementary" relationship between 2 opposite charges in
balance", and that things may have a dual nature (as the
electron is both particle and wave) but we can only experience one
aspect at a time. In addition to his major contributions to
theoretical physics, Bohr was an excellent administrator. The
institute he headed is now named after him, and he helped establish
CERN [Centre for European Research in Nuclear Physics or
European Organization for Nuclear Research
with Europe's great particle accelerator and research station. The
World Wide Web (www) was invented by Tim Berners-Lee, a
scientist at CERN, in1989]. Bohr died at home in
1962, following a stroke.

Denmark is made up
of the Jutland peninsula, bordering Germany, and nearly 500 islands.
The country is blessed with fertile grasslands with a moderate
climate, and more than 70% of the country is farmland. Farming is an
important profession in Denmark. According to the National
Geographic Picture Atlas of Our World, young farmers must earn a
farmer’s license before they can purchase a land. Denmark is famous
for its agricultural exports, including cheese, butter, and ham.
Those of you who grew up with someone of Danish heritage in your
family or who lived in a community with Danish roots have likely,
been fortunate enough to sample Danish baked goods.
Archaeological excavations and finds from the stone age show that
more than 4,000 years B.C. the first Danes began to burn down
forests in order to cultivate land and to keep livestock. The first
cattle was probably wild oxen, which were caught and kept in a
close (shed). The Vikings (old residents) kept cows, and medieval frescos
(old mural painters) show women
churning butter. From early on, dairy products formed part of the
farmer’s tithes (tax) to his king, church and lord of the manor
(large home). During
the 16th and 17th centuries the Danes became increasingly skilled in
dairy production. eg.. King Christian IV’s letters show that the court
farms were well informed about dairy layouts and equipment. Denmark
is the world’s top five dairy exporting nations.
Danish honey is a well-regulated brand for naturally produced
and carefully processed soft and aromatic honey. The product is a
healthy alternative to a sweetener. The main honeys are
multi flora, with some dandelion (herbs), rapeseed (seed of rape
plant's) honey, white clover and
lime tree honey.
Yet another excellent tea gift was given in 1660, when
Charles II (referred to as the Merry Christmas Monarch of England) brought
a gift of tea to England. When he first married the Portuguese
Princess Catherine, they were forced to live in exile in
Denmark. At that
time in Denmark, tea was already enjoying widespread popularity and
both Charles and Catherine were fans. When the couple was able to return to England,
they brought a
chest of tea with them, which was met with thirsty enthusiasm by the
British court. This gift provoked the craze for tea in Great Britain.
