Answer 1

Respuesta:

- The compound microscope (1592)

Zacharías Hanssen, manufacturer of glasses of Dutch origin, and his son Hans Jannsen were the creators of the compound optical microscope in 1592.

The idea arose from an experiment in which they introduced lenses with magnification into a tube and discovered that the objects were observed better.

Subsequently, the invention was improved in 1655 by Robert Hooke.

Answer 2

Respuesta:

Before the development of the electric telephone, the term "telephone" was applied to other inventions, and not all early researchers of the electrical device called it "telephone". Perhaps the earliest use of the word for a communications system was the telephon of Gottfried Huth in 1796. Huth proposed an alternative to the optical telegraph of Claude Chappe in which the operators in the signalling towers would shout to each other by means of what he called "speaking tubes", but would now be called giant megaphones. A communication device for sailing vessels called a "telephone" was invented by the captain John Taylor in 1844. This instrument used four air horns to communicate with vessels in foggy weather

Johann Philipp Reis used the term in reference to his invention, commonly known as the Reis telephone, in c. 1860. His device appears to be the first device based on conversion of sound into electrical impulses. The term telephone was adopted into the vocabulary of many languages.

Credit for the invention of the electric telephone is frequently disputed. As with other influential inventions such as radio, television, the light bulb, and the computer, several inventors pioneered experimental work on voice transmission over a wire and improved on each other's ideas. New controversies over the issue still arise from time to time. Charles Bourseul, Antonio Meucci, Johann Philipp Reis, Alexander Graham Bell, and Elisha Gray, amongst others, have all been credited with the invention of the telephone

Alexander Graham Bell was the first to be awarded a patent for the electric telephone by the United States Patent and Trademark Office (USPTO) in March 1876. The Bell patents were forensically victorious and commercially decisive. That first patent by Bell was the master patent of the telephone, from which other patents for electric telephone devices and features flowed.

In 1876, shortly after Bell's patent application, Hungarian engineer Tivadar Puskás proposed the telephone switch, which allowed for the formation of telephone exchanges, and eventually networks

In the United Kingdom the blower is used as a slang term for a telephone. The term came from navy slang for a speaking tube.
