1. An 1888 story describes a system where people in the year 2000 can obtain whatever goods they desire from public storehouses without needing business transactions. An identification document called an "X" allows people to access goods and can be used like money both in America and Europe. 2. The story predicted the development of credit cards, which became widespread in the 1950s. 3. The document discusses an identification system and access to goods without transactions, predicting a key feature of modern economic systems.

3. An 1888 story's plot involves a man from 1887 who falls asleep and wakes up in the year
2000. The story describes: A X [is] issued him with which he procures at the public
storehouses, found in every community, whatever he desires whenever he desires it. This
arrangement, you will see, totally obviates the necessity for business transactions of any
sort between individuals and consumers… An American X... is just as good in Europe as
American gold used to be, and on precisely the same condition, namely, that it be
exchanged into the currency of the country you are traveling in.
What had he predicted in the book, which became a reality in 1950s?

7. Synthesized in 1706 in Berlin, it had been accidentally discovered when in a chemist’s
lab, potash interacted with animal blood and the two red components surprisingly
produced X in the reaction. Its fans ranged from Picasso to the Japanese great Hokusai.
The Prussian army had famously adopted it in their uniforms. It is also pretty versatile
and has been in use by architects and engineers.
What is X?

9. In the 19th century, many females were diagnosed with this physical illness. It was
supposedly caused by movement of the woman’s uterus to various parts of her body, as
it became light and dry due to lack of body fluids. The symptoms were crazy mood
swings and at times, maniacal laughter and unpredictable state of mind.
Although this disease still exists, it is no longer viewed or treated the same way.
What is this peculiar disease that previously only plagued women but later found to be
uniform in its infective capabilities?

13. While working at the Royal Observatory under Cassini, he was recording the observations of Galilean moon Io.
The numbers didn’t seem to fit the calculations. He regularly observed the eclipses of Io over a period of time
and he noticed something peculiar. He noticed that the time between two successive eclipses was shorter when
Earth was moving towards Jupiter than when Earth was moving away from Jupiter. In numbers, the eclipses of Io
occurred 9 minutes earlier than expected when Earth was closest to Jupiter and occurred 9 minutes later than
expected when Earth was farthest to Jupiter.
He deduced that it would be only possible on one condition which ran quite contradictory to Rene Descartes. It
is believed that Newton and Hailey were supporters of this theory. His theory led to the calculation of the
numerical value of a particular universal constant.
Identify the person and the universal constant we are talking about.

15. The reasons for this phenomenon which was prevalent in mostly in Central Europe
between 14th to 17th century can be
1. Ergot poisoning - ergots grow on crops during floods; when people ate this
affected crops they experienced hallucinations and convulsions.
2. Historian Gregor Rehmann calls it concept of illness based on religious ideas.
It seems like a majority of factors came together for this to happen. So it is quite
unlikely that it will be repeated in the modern world.
What?

16. Dancing Mania / Dancing Plague

17. "In December I caused a mare to be tied down alive on her back; she was fourteen hands
high, and about fourteen years of age; had a fistula of her withers, was neither very lean nor
yet lusty, having laid open the left crural artery about three inches from her belly, I inserted
into it a brass pipe whose bore was one sixth of an inch in diameter... I fixed a glass tube of
nearly the same diameter which was nine feet in length: then untying the ligature, ____ rose
in the tube 8 feet 3 inches perpendicular above the level of the left ventricle of the heart, ...
when it was at its full height it would rise and fall at and after each _____ 2, 3, or 4 inches”
This was an experiment in 1773, considered to be the first measurement of what? (blanks are
different and are present to hide the obvious)

19. During the colonial period, when the Britishers travelled to India as workers of the company or
servants of the empire, most of them use to travel alone, i.e. not bring their wives with them on this
long journey which covered almost the whole of African coastline. This directly meant that the
Britishers slowly acquired a taste for Indian food which they modified to suit their tastes. The coffee
houses of India too started modifying the Indian dishes for its british customers, mulligatawny being
a famous example of this.
Due to a famous development in the Sci-tech world, the British memsahibs also started arriving in
India which meant that Indian food was now being replaced by regular English roasts and pies at the
British table.
What development brought this change?

21. For the experiment two small balls were added on the ends of a
rigid rod which in turn was connected to a torsion balance.
The larger balls were brought closer to the smaller balls and
measure the twist in the wire. The angular displacement was
measured by the deflection of the light ray on the mirror. The
observations were expected to be very small because of the size
of balls involved, thus the disturbances had to be controlled.
Although this experiment was setup to measure the density of the
Earth, it proved successful in calculating which universal
constant?

23. The reason why the monk chose this plant for his experiment was
1. Need little care and grow fast
2. Can cross-pollinate or self-pollinate
3. Show only one of the two variations of many characteristics
Thus, this professor of Physics came up with this theory and is rightly called the
Father of X. Unknowingly he had contributed to Darwin’s theory of evolution, although
he himself didn’t believe in it being a man of strong religious conviction.
Tell me X.

25. This semi-precious stone which once even had the same price as Gold. It is not actually made of a single
mineral but is a mixture, the presence of sulfur in the compound gives it the characteristic color. The
Europeans imported it from Asia where around 1kg of mining product would give about just 30g of the
required substance.
When used by artists it was reserved for the most important or central figure, after the powdered form of
the stone is mixed with melted wax, oils, resin, and lye.
In 1826 saw the invention of a synthetic version by a French chemist who achieved it through a complex
combination of silicon, oxygen, sulfur and few more elements bound by various chemical processes. The
synthetic version being much cheaper later replaced the original.
By which two word name do we know this semi-precious stone? The images in the next slide may help you.

28. There seems to be sufficient evidence that Y did exist in history, albeit in a very
different sense. It seems that a particular disease X was known to cause the Y
syndrome. Although the “biting and infecting” part is just exaggeration, the part where
people turn in to Y every month was partially true.
What disease am I talking about which caused men to look like Y and the apparent
counter measure to this Y syndrome re appeared each month (full moons).
Y is a very popular, perhaps the most popular, mythological creature of all times.
Identify X & Y.

The name of this problem comes from the the Greek word for the shortest time/delay. X wasn’t
the first one who had come up with this problem as Galileo had already mentioned it in his
works but instead of taking two points he had taken a point and a line.
This was one of the first problems which used the concept of ‘Y of variations’. Total 5 solutions
of this problem were received, which included solutions from X and his brother himself along
with 2 rivals who had disputes over Y. The mathematicians were from different european
countries as has been quoted, “that the three great nations, Germany, England, France, each
one of their own to unite with myself in such a beautiful search, all finding the same truth.”
Which problem am I talking about?

31. Brachistochrone

32. At a time when it was believed that only 6 of _____ existed, X used these (refer to the image) to
explain them, because he believed that both must have a connection that is why only a certain
number of them exist. After inserting these into the ‘perfect’ shape, he noticed that it didn’t fit
with the observations. After repeatedly trying to fit the observations with his theory, at last X
was convinced that his theory was incorrect so he started working on an alternative theory by
modifying the ‘perfect’ shape which resulted in the laws that are still taught to us.
Who is X?
