1. PRELIMS -Answers

2. 1.
• Soon after the _____X_____ Project which lasted from 1939-1946 a few of its
original team members who were devastated by the effects of their prior project
initiated this programme which serves as a indicator to the world regarding how
fast they are destroying it.To achieve this effect they made use of an extremely
ominous symbol , _____Y______ ___Z___ which gets updated every year.FITB.

• In the following slide you will see a computer stimulated image of
foliage as viewed by a certain species X, because our reality need not
be same X’s reality.Not only has X the ability to see RGB spectrum like
humans but also a bit of Y spectrum as shown in the image. This
added capability enables X to view everything in a more 3
dimensional manner than what humans can see which makes them
more capable than humans to maneuver around obstacles .ID X and
Y

6. • X- birds Y-ultraviolet spectrum

7. 3.
• Over the past century this specific point X has shifted from the coast of Northern
Canada at present moving towards Siberia in Russia .Earlier X used to move only a
distance of about 10 miles every year but recently there has been a drastic
change as X moves about 40 miles every year, over the past 150 years X has
travelled about 600 miles.This unprecedented travel which has baffled the
scientific community has now affected the US military amid the partial
Government shutdown as they are unable to get an exact location of X. ID X.

8. • MAGNETIC NORTH POLE

9. 4.
• Scientists at MIT have developed a way to transmit X to specified people using
lasers which are safe to the skin and the eye of any person in any setting. The
technique employed by the team involves the absorption of light by water vapour
whose vibration will in turn emit X. The scientists claim that this technique would
work even in arid atmospheres as water vapour is a good absorbent of lasers. ID
X.

11. 5.
• In the following slide the you will see an image clicked by X at Vera Rubin
Ridge before its descend into the clay region of Mount Sharp to collect and
analyse mineral data. If you were in the place of X you would have called this
image Y.ID X & Y

12. • X- CURIOSITY ROVER Y- SELFIE

13. 6.
• Last year on Valentines day a plea was sent out by conversationalists on behalf of
an ideal bachelor fondly called X , a Bolivian Sehuencas frog as he had been
lacking a soul mate for the past 10 years. Recently his wish was granted when a
wildlife conservation team was able find his soul mate named Y from the rain
forests of Bolivia .Till she was found X was supposed to be the last member of
that specific species which would otherwise have been extinct in the next five
years.
• ID X and Y , the ideal couple.

• Called Computed Axial Lithography (CAL), the process starts with a Computer-
Aided Design (CAD) model. Researchers use projected photons to illuminate the
syrup-like resin, creating a continuously shifting video of projections as the vial
rotates. The projection is calculated at each angle, researchers run an
optimization algorithm and the result is a series of images that appears as a
rotating video projection that can be played at a rate adjusted to the rotation of
the resin vial. After several minutes, ___________ appears, the researchers stop
the exposure and drain the uncured liquid, leaving only the finished product.This
process can roughly be termed as the reverse of a CT scan.What is the technique
used for?

16. • 3D PRINTING USING LIGHT

17. 8.
• Similar to the optical tweezers scientists at University of Bristol have found a
novel method to manipulate ___X___ to create a force field which is capable of
moving objects and in a recent breakthrough they were able to sew threads
making use of this technique opening doors to a whole new level of research in
drug delivery and surgery.At present a crude form of this technique is quite
common in several medical institutes to cure certain ailments, but with the above
research the applications are unbound. FITB

18. • SOUND AGAIN

• Alcometer is a device which makes use of the principle of differential absorption
of wavelength by a sample.In the case of Alcometer an infrared cell is used as the
source to allow infrared radiation to pass through the sample a detector is kept at
the otherside to measure the the intensity of the light received. If the intensity of
light received is less then sample is said to have a high content of X otherwise the
detector will flag the sample to be normal.Im sure many of you would have
encountered this device.What am I talking about?

20. • ALCOMETER MEASURES THE AMOUNT OF ALCOHOL IN THE BLOOD

21. 10.
• In the following video the working of a NIST 4 balance or Kibble balance has been
illustrated , In recent news these terms were trending as it brought about a
radical change for the scientific community but not much of a change to the
common man.What historic event are we blabbering about?

23. • REDEFINITION OF THE 1KG

24. 11.
• This dream project of India which will put India in the front lines of this specific
race is a portmanteau of two hindi words X and Y with the latter one loosely
meaning Boat in hindi. This project XY requires enormous man hours to complete
and has a considerable amount of risk involved. Give XY

• Microsoft is now working on a project called Natik which aims at providing data
connectivity to
• the costal regions.A moonshot as they claim it to be employs cutting edge
technology to anchor the self sustained Datacenter under water , Natik makes
use of tidal waves to generate electricity. At present there are 864 servers
arranged in this shipping sized container submerged in the seafloor close to
Scotlands Orkney Islands.Eventhough the team has confusions regarding the
economic viability of the project there is certainly one factor in this project
compared to other land based data centers which saves them a lot of money.Put
FUNDA.

• Modern X typically consist of four thin layers: backing, release coating, primer,
and adhesive, . Flexible backing materials are usually about 50–100 µm thick and
include paper, polyethylene or polypropylene films, cloth, metal foil, vinyl, or
foam. Backings have a coating on each side. The release coating, often a polyvinyl
carbamate, prevents the X from adhering to itself when pulled off itself. The
other side of the backing is covered with a primer that has an affinity for the
adhesive and allows it to attach to the backing.What common household item are
we talking about?

• Read through the following physics limerickand identify which ill fated term
Einstein tackled which he later called the biggest blunder of his life
“Though Einstein's equations were firm,
There was one thing that did make him squirm.
A cosmos expandable
Was not understandable,
So he tacked on that ill-fated term”

• The word Oumuamua has its origin in Hawaiian ou, meaning 'reach out for', and
mua, reduplicated for emphasis, meaning 'first, in advance of' .Basically
Oumuamua means a messenger or scout sent from the distant past to reach out
to us.Why has this odd name caught our attention since the October of 2017 ?
And why is it baffling the scientific community?

39. • Oumuamua is the first and
currently only interstellar object
detected passing through the
Solar System.
• Scientists cant figure out its
origin or its heading as it seems
unaffected by the gravitational
fields

40. 19.
• A particular reaction involves the use of a pigment called the luciferin
and an enzyme called luciferase, which produces a modification of the
original pigment with the release of a characteristic form of energy. It
is found commonly in marine organisms, and is believed to be a
mechanism for self defense through startle, as a burglar alarm or for
mate attraction. What is this phenomenon called?

41. • Bioluminiscence

42. 20.
• The lobsters underbelly is made of chitin, a thin stretchy substance. It
is made of 90% of water which lends the material elasticity. Stretching
the material, actually makes it stiffer and it has a layered arrangement
of the membrane, so cuts and gouges do not propagate into the
interior.
• This property has enabled the lobsters belly to be used as an
alternative to making what?

43. • Car Tires.
