The spinning jenny had a big part in these developments. Once raw materials such as

cotton or wool were gathered, they had to be spun into yarn --

an often laborious task for people.

Niepce placed an engraving onto a metal plate coated in bitumen, and

then exposed it to light. The shadowy areas of the engraving blocked light,

but the whiter areas permitted light to react with the chemicals on the plate. When Niepce placed the metal plate in

a solvent, gradually an image, until then invisible, appeared.

Carrier stared through the mist and realized that he could dry air by

passing it through water to create fog. Doing so would make it possible

to manufacture air with specific amounts of moisture in it.

The United States Government began the serious undertaking

known then only as "The Manhattan Project." Simply put,

the Manhattan Project was committed to expediting research

that would produce a viable atomic bomb.

A cotton gin is a machine that quickly and easily separates cotton fibers from their seeds, allowing for

much greater productivity than manual cotton separation. The fibers are processed into clothing or other cotton goods, and any undamaged

cotton was used for clothes.

Bell's telephone transmitter (microphone) consisted of a double electromagnet, in front of which a membrane, stretched on a ring,

carried an oblong piece of soft iron cemented to its middle. A funnel-

shaped mouthpiece directed the voice sounds upon the membrane, and as it

vibrated, the soft iron "armature" induced corresponding currents in the

coils of the electromagnet.

The invention of the television was the work of many individuals in the 19th and early 20th century.

Facsimile transmission systems for still photographs pioneered

methods of mechanical scanning of images in the early 19th

century.

Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. With the continued

miniaturization of computing resources, and advancements in portable battery life, portable

computers grew in popularity in the 2000s.

In fact, some historians claim there were over 20 inventors of incandescent lamps prior to Edison’s version. However, Edison is often

credited with the invention because his version was able to outstrip the earlier versions

because of a combination of three factors: an effective incandescent material, a higher

vacuum than others were able to achieve and a high resistance that made power distribution

from a centralized source economically viable.

Steam-powered self-propelled vehicles large

enough to transport people and cargo were first

devised in the late 18th century.

The early history of radio is the history of technology that produced radio

instruments that use radio waves. The idea of wireless communication predates the discovery of "radio" with experiments in "wireless telegraphy" via inductive and

capacitive induction and transmission through the ground, water, and even train

tracks.

The first mobile telephones were barely portable compared to today's compact hand-held devices. Along

with the process of developing more portable technology, drastic changes have taken place in the networking of wireless communication and the

prevalence of its use.

The Technology Era


The Spinning Jenny was the most form of technology in order to make best clothing.


The Cotton Gin was invented by Eli Whitney was used to get the cotton fiber off the thorns.


The light bulb was introduced during this period to be able to see in the darkness.


The first camera and photography was taken during this time period were it was used to capture events.


The Telephone was the first thing that introduced distant communication.


The first automobiles took time to perfect, but once it was transportation was a lot easier.

20th Century and Modern World1914 CE-Present

Air conditioning was invented using humidity and moisture and release air for people to cool off.


The radio was invented and as well the first live broadcast as well.


Transmission of televised signals were introduced in order to bring motion picture on screens.


During this time there were also chaotic wars and the first atomic bomb was invented.


The digital computer was invented bringing communication a whole lot different.


The mobile cellphone was invented which helped with communication portable.
