2. You are just a wheeled, self-powered motor vehicle usedfor
transportation. Most definitions of the term specify that cars
aredesigned to run primarily on roads, to have seating for one to
eightpeople, to typically have four wheels, and to be constructed
principally forthe transport of people rather than goods.-Carth
vader

had beendesigned in 1878.

13. An airplane or aero plane (informally plane) is a powered,
fixed-wingaircraft that is propelled forward by thrust from a jet
engine orpropeller. Airplanes come in a variety of sizes,
shapes,and wing configurations. The broad spectrum of uses for
airplanesincludes recreation, transportation of goods and people,
military, andresearch. Most airplanes are flown by a pilot on board
the aircraft, butsome are designed to be remotely or
computer-controlled.

15. Wright Flyer III was capable of fullycontrollable, stable
flight for substantialperiods.
16. The first 'operational' jet aircraft was theGerman Heinkel
He 178, which wastested in 1939.

26. Mechanizedagriculture is theprocess ofusing
agriculturalmachinery to mechanize the workof agriculture,
greatlyincreasing farmworker productivity. Inmodern times,
poweredmachinery has replacedmany jobs formerlycarried out by men
oranimals such as oxen ,horses and mules.
27. A mechanical seed spacing and depth placingdevice that
increased crop yields and saved seed
28. Steam power wasapplied to threshingmachines in the late19th
century. Therewere steam enginesthat moved around onwheels under
theirown power forsupplying temporarypower to stationarythreshing
machines.These werecalled road engines.
29. Mechanized AgriculturePresent
30. A cotton picker at work. The first successfulmodels were
introduced in the mid-1940s andeach could do the work of 50 hand
pickers.
32. Air conditioning (often referred toas A/C, AC or aircon) is
the process of altering theproperties of air (primarily
temperatureand humidity) to more comfortable conditions,typically
with the aim of distributing the conditionedair to an occupied
space to improve thermalcomfort and indoor air quality.
33. The 2nd-century Chineseinventor Ding Huan ofthe Han Dynasty
inventeda rotary fan for airconditioning, with sevenwheels 3 m (9.8
ft) indiameter and manuallypowered.
34. In 1902, the firstmodern electricalair conditioningunitwas
invented byWillisCarrier in Buffalo,New York

37. 3. Evaporative Cooling 4. Free Cooling
38. Refrigeration is aprocess in which workis done tomove heat
from onelocation to another.The work of heattransport
istraditionally drivenby mechanical work,but can also be
drivenbyheat, magnetism, electricity, laser, or othermeans.
39. ICE HARVESTINGBefore 1830, few Americans used ice
torefrigerate foods due to a lack of ice-storehousesand iceboxes.
As these two thingsbecame more widely available, individuals
usedaxes and saws to harvest ice for theirstorehouses. This method
proved to be difficult,dangerous, and certainly did not
resembleanything that could be duplicated on acommercial
scale.

44. Materials science, also commonlyknown as materials science
and engineering,is an interdisciplinary field which deals withthe
discovery and design of new materials.Though it is a relatively new
scientific fieldthat involves studying materials through
thematerials paradigm (synthesis, structure,properties and
performance), its intellectualorigins reach back to the emerging
fields ofchemistry, mineralogy and engineeringduring the
Enlightenment.

46. Graphene. It is a one-carbonatom thick. It islike a paper
sheet ofcarbon. Because of itsunique composition andstructure it
also hassome uniquecharacteristics andbecause it is unique itmeans
some of thesecharacteristics onlybelong to graphene. Ithas many
