Объяснение:
Edinburgh-born scientist Alexander Graham Bell patented his invention of the telephone in 1876. The following year, the great American inventor Thomas Edison produced the first working telephone. With telephones soon becoming rapidly available, the days of letter-writing became numbered.
Computer (20th Century)
The computer has been another life-transforming invention. British mathematician Charles Babbage designed a form of computer in the mid-1830s, but it was not until more than a century later that theory was put into practice. Now, a whole generation has grown up with calculators, windows, icons, computer games and word processors, and the Internet and e-mail have transformed communication and information.

Фотография (начало 19 века)
Леонардо да Винчи описал фотографические принципы камеры-обскуры в начале 1515. Но только в 1835 француз Луи Дагер создал камеру для фотографий. Системы постепенно совершенствовались в течение многих лет, на радость счастливых любителей фотогрфировать и отчаяние тех, кто вынужден преодолевать просмотры бесконечных фотографий праздников друзей.
Телефон (1876)
Рожденный в Эдинбурге, ученый Александр Грэхем Белл запатентовал свое изобретение телефона в 1876 году. На следующий год великий американский изобретатель Томас Эдисон произвел первый рабочий телефон. С доступностью телефонов, написание писем стало исчезать.
Компьютер (двадцатый век)
Компьютер стал еще одним изобретением, преобразующим жизнь. Английский математик Чарльз Бэббидж разработал форму компьютера в середине 1830-х годов, но только более чем столетие спустя, теория была введена в практику. Теперь, целое поколение выросло с калькуляторами, окнами, значками, компьютерными играми и текстовыми процессорами, а также Интернет и электронная почта изменили общение и информацию.
