18. One of the first to discuss the possibility of an _______
______ temperature was Robert Boyle. His 1665 book
‘New Experiments and Observations touching Cold’,
articulated the dispute known as the primum frigidum.
He said that, "There is some body or other that is of its
own nature supremely cold and by participation of
which all other bodies obtain that quality”.
What was he discussing about?
24. In addition to his work in theoretical physics, X has been
credited with pioneering the field of quantum computing,
and introducing the concept of nanotechnology.
He developed a widely used pictorial representation
scheme for the mathematical expressions governing the
behaviour of subatomic particles, which later became
known as X diagrams.
He assisted in the development of the atomic bomb and
was a member of the panel that investigated the Space
Shuttle Challenger disaster.
X also became known through his semi-autobiographical
books (Surely You're Joking, Mr. X! and What Do You Care
What Other People Think?)

26. A literal translation of this word is "to make into
nothing". In Physics, it is used to denote the
process that occurs when a subatomic
particle collides with its respective antiparticle.
Since energy and momentum must be conserved,
the particles are not actually made into nothing,
but rather into new particles. Antiparticles have
exactly opposite additive quantum numbers from
particles, so the sums of all quantum numbers of
the original pair are zero.

28. According to folklore, in 1589 X dropped two weights from
the top of Y, one weighing 1 pound and the other 10
pounds, and measured the objects' fall and recorded the
following:
“Imagine two objects, one light and one heavier are
connected to each other by a string. Drop this system of
objects from the top of a tower. If we assume heavier objects
do indeed fall faster than lighter ones (and conversely,
lighter objects fall slower), the string will soon pull taut as
the lighter object retards the fall of the heavier object. But
the system considered as a whole is heavier than the heavy
object alone, and therefore should fall faster. This
contradiction leads one to conclude the assumption is false.”

30. __________ is the interdisciplinary science that deals
with the study of all mechanical waves in gases,
liquids, and solids including vibration, sound,
ultrasound and infrasound.
The word is derived from the Greek word ἀκουστικός
,meaning "of or for hearing, ready to hear“ and that
from ἀκουστός ,"heard, audible",which in turn derives
from the verb ἀκούω ,"I hear".

36. "For all these years, we have been looking at the wrong
number when we have been looking at X. X simply isn't
the most natural number that we should associate with
a circle . The proper number is Y. How much simpler
it'd be if we just used Y instead of X. The circle would
have Y radians, a semicircle would have half Y, a
quarter of a circle a quarter Y, and so on. You don't have
to think," Dr.Kevin Houston at the University of Leeds
told The Times newspaper.

40. This machine uses a powerful magnetic field to align
the magnetization of some atoms in the body,
and radio frequency fields to systematically alter the
alignment of this magnetization. This causes the
nuclei to produce a rotating magnetic field detectable
by the scanner—and this information is recorded to
construct an image of the scanned area of the body.
Strong magnetic field gradients cause nuclei at
different locations to rotate at different speeds & 3-D
spatial information can be obtained by providing
gradients in each direction.

His long, thin torso offers low drag.
His arms span 6 feet 7 inches (201 cm)—
disproportionate to his height of 6 feet 4 inches (193
cm)—and act as long, propulsive "paddles“.
His relatively short legs lower drag, and add the speed
enhancement of a hydrofoil.
His size 14 feet provide the effect of flippers.
His hypermobile ankles can extend beyond the pointe
of a ballet dancer, enabling him to whip his feet.

48. 1. After the core of an aging massive star ceases generating
energy from nuclear fusion, it may undergo sudden
gravitational collapse into a neutron star or black hole,
releasing gravitational potential energy that heats and
expels the star's outer layers. Alternatively a white dwarf
star may accumulate sufficient material from a stellar
companion to raise its core temperature enough to ignite
carbon fusion, at which point it undergoes runaway nuclear
fusion. Stellar cores whose furnaces have permanently gone
out collapse when their masses exceed the Chandrasekhar
limit, while accreting white dwarfs ignite as they approach
this limit (roughly 1.38 times the solar mass).

50. 2.The process begins with the compressor. Ammonia gas is
compressed until it becomes very hot from the increased
pressure. This heated gas flows through the coils behind it,
which allow excess heat to be released into the surrounding
air. Eventually the ammonia cools down to the point where it
becomes a liquid. Essentially, the expansion valve has such a
small opening that the liquid ammonia is turned into a very
cold, fast-moving mist, evaporating as it travels through the
coils. Since this evaporation occurs at -27 degrees F (-32
degrees Celsius), the ammonia draws heat from the
surrounding area. This is the Second Law of Thermodynamics
in effect.
As the evaporating ammonia gas absorbs more heat, its
temperature rises. The cool ammonia still draws heat from the
warmer objects in it. The ammonia gas is drawn back into the
compressor, where the entire cycle of pressurization and
evaporation begins anew.

54. 4.This consists of a gain medium inside a highly reflective optical cavity,
as well as a means to supply energy to the gain medium. In its simplest
form, a cavity consists of two mirrors arranged such that light bounces
back and forth, each time passing through the gain medium. Typically
one of the two mirrors, the output coupler, is partially transparent. The
output is emitted through this mirror.
Light of a specific wavelength that passes through the gain medium is
amplified ; the surrounding mirrors ensure that most of the light
makes many passes through the gain medium, being amplified
repeatedly. Part of the light that is between the mirrors (that is, within
the cavity) passes through the partially transparent mirror and escapes.
The process of supplying the energy required is called pumping. The
energy is typically supplied as an electrical current or as light at a
different wavelength.

56. 5.It result from emissions of photons in the Earth's upper
atmosphere, above 80 km from ionized nitrogen atoms
regaining an electron, and oxygen and nitrogen atoms
returning from an excited state to ground state. They are
ionized or excited by the collision of solar wind and
magnetospheric particles being funneled down and
accelerated along the Earth's magnetic field lines;
excitation energy is lost by the emission of a photon of
light, or by collision with another atom or molecule:
Oxygen emissions-
Green or brownish-red, depending on the amount of energy
absorbed.
Nitrogen emissions
Blue or red. Blue if the atom regains an electron after it has
been ionized. Red if returning to ground state from an excited
state.

60. 1.He is one of the founding members of the National
Geographic Society in 1888.
Both his mother and wife were deaf, profoundly
influencing his life's work. His research on hearing
and speech further led him to experiment with
hearing devices which eventually culminated in hi
greatest invention. In retrospect, he considered his
most famous invention an intrusion on his real work as
a scientist and refused to have it in his study.

63. 2. Albert Einstein kept a photograph of X on his study wall alongside
pictures of Isaac Newton and James Clerk Maxwell.
X established that magnetism could affect rays of light and that there was
an underlying relationship between the two phenomena. His inventions
of electromagnetic rotary devices formed the foundation of electric motor
technology, and it was largely due to his efforts that electricity became
viable for use in technology.
As a chemist, he discovered benzene, invented an early form of the
Bunsen burner and the system of oxidation numbers, and popularised
terminology such as anode, cathode, electrode, and ion.
Although X received little formal education and knew little of higher
mathematics, like calculus, he was one of the most influential scientists in
history.
He is referred to as the best experimentalist in the history of science.

the River _____, which flows close by his lab at the
University of Glasgow, Scotland.
He was the first UK scientist to be elevated to the
House of Lords.
He proposed the idea of “Heat descending from a body
A at the temperature T° of this scale, to a body B at the
temperature (T−1)°, would give out the same mechanical
effect [work], whatever be the number T. Such a scale
would be quite independent of the physical properties of
any specific substance.”
