Irrigation
(SISTEMAS DE RIEGO) Is the artificial application of water to the land or soil. It allowed for a greater yield of crops year round making larger populations possible.
Plow
(SISTEMA DE ARADO)This tool allowed farmers to till much more land in one day. This made it take less people and time to complete the task.
Printing Press
(Prensa de impresión) Developed around 1440 by Johannes Gutenberg. It was able to create as many as 3,600 pages per day. This helped make books available for anyone, poor or rich.
Compass
(Compás) Originally invented in China, by the 14th century. It provided explorers with a reliable method for traversing the world's oceans, a breakthrough that ignited the Age of Discovery and won Europe the wealth and power that later fueled the Industrial Revolution.
Paper Currency
(Moneda en papel) Ushered in a new era of international monetary regulation that changed the face of global economics.
Steel
(metal) It fueled the Industrial Revolution and built modern cities.
Electric Light
(Luz eléctrica) It was Thomas Edison who patented the first long-lasting light bulbs in 1879 and 1880, liberating society from a near-total reliance on daylight.
Domestication of the Horse
(Domesticación del caballo) Horses have been inextricably tied to human development. They enabled people to travel great distances and gave different cultures the chance to trade and exchange ideas and technology.
Transistors
(Transistores) Originally used in radios, they have since become an elemental piece of the circuitry in countless electronic devices including televisions, cell phones and computers.
Magnifying Lenses
(lentes de aumento) This lenses have since led to new breakthroughs in an abundance of fields including astronomy, biology, archaeology, optometry and surgery.
Telegraphy
(telégrafo) The ability to send messages rapidly across great distances made an indelible impact on government, trade, banking, industry, warfare and news media, and formed the bedrock of the information age. Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed the electrical telegraph system.
Antibiotics
Like penicillin, vancomycin, cephalosporin and streptomycin have gone on to fight nearly every known form of infection, including influenza, malaria, meningitis, tuberculosis and other transmitted diseases.
Steam Engine
(Máquina de vapor) It's basic principle of energy-into-motion set the stage for later innovations like internal combustion engines and jet turbines, which prompted the rise of cars and aircraft during the 20th century.
Gunpowder
(la pólvora) Revolutionized warfare by being used to produce projectile weapons like cannons and guns.
Camera
It's innovation lead to other innovations like moving picture shows.
Cotton Gin
A machine that quickly and easily separates cotton fibers from their seeds, allowing for much greater productivity than manual cotton separation.
Refrigeration
The ability to keep foods preserved longer.
Windmills
Wind energy was important to people before electricity. It can grind grain or pump fresh water and irrigate crops.
Internet
A mass storage of information accessible almost anywhere can greatly help the technological innovations of society.
Longbow
The most deadly weapon well into the 16th century. It could decimate entire legions from 400 yards away.
Arch
Building buildings using this invention allowed for larger structures to be built.
The Wall
Constructed around cities protected citizens from outside threats.
Rail Road
This form of transportation allowed society to ship large quantities of materials and people across vast distances of land at a high rate of speed.
Automobile
Is a wheeled, self-powered motor vehicle used for transportation. Henry Ford revolutionized the mass production of automobiles in 1914 making them available for everyone.
Airplane
Is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. The Wright brothers flights in 1903 showed people that man could fly. Air travel is now the most convent way to travel long distances
Computers
The first ones were developed in the early 1940's and today almost everything is run by this revolutionary invention.
Highways
Connected high traffic areas with reliable safe roads. The first was the German Autobahn and it was created for military purposes. This allowed for the fast transport of military equipment and personnel.
Spacecraft
Is a vehicle, vessel or machine designed to fly in outer space. The space race was a big part of American cold war history. This invention allowed access to the moon and stars. It showed American dominance in technology.
