Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

SUMMARY
=======
A timeline of United States inventions (before 1890) encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Colonial Period to the Gilded Age, which have been achieved by inventors who are either native-born or naturalized citizens of the United States. Copyright protection secures a person's right to his or her first-to-invent claim of the original invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution, which gives the following enumerated power to the United States Congress:
In 1641, the first patent in North America was issued to Samuel Winslow by the General Court of Massachusetts for a new method of making salt. On April 10, 1790, President George Washington signed the Patent Act of 1790 (1 Stat. 109) into law proclaiming that patents were to be authorized for any useful art, manufacture, engine, machine, or device, or any improvement therein not before known or used. On July 31, 1790, Samuel Hopkins of Pittsford, Vermont became the first person in the United States to file and to be granted a patent for an improved method of Making Pot and Pearl Ashes. The Patent Act of 1836 (Ch. 357, 5 Stat. 117) further clarified United States patent law to the extent of establishing a patent office where patent applications are filed, processed, and granted, contingent upon the language and scope of the claimant's invention, for a patent term of 14 years with an extension of up to an additional 7 years. However, the Uruguay Round Agreements Act of 1994 (URAA) changed the patent term in the United States to a total of 20 years, effective for patent applications filed on or after June 8, 1995, thus bringing United States patent law further into conformity with international patent law. The modern-day provisions of the law applied to inventions are laid out in Title 35 of the United States Code (Ch. 950, sec. 1, 66 Stat. 792).
From 1836 to 2011, the United States Patent and Trademark Office (USPTO) has granted a total of 7,861,317 patents relating to several well-known inventions appearing throughout the timeline below.

SUMMARY
=======
The election of President and Vice President of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the 50 U.S. states or in Washington, D.C. cast ballots not directly for those offices, but instead for members of the U.S. Electoral College, known as electors. These electors then in turn cast direct votes, known as electoral votes, for President, and for Vice President. The candidate who receives an absolute majority of electoral votes (at least 270 out of a total of 538, since the Twenty-Third Amendment granting voting rights to citizens of Washington, D.C.) is then elected to that office. If no candidate receives an absolute majority of the votes for President, the House of Representatives chooses the winner; if no one receives an absolute majority of the votes for Vice President, then the Senate chooses the winner.
The Electoral College and its procedure are established in the U.S. Constitution by Article II, Section 1, Clauses 2 and 4; and the Twelfth Amendment (which replaced Clause 3 after its ratification in 1804). Under Clause 2, each of the states casts as many electoral votes as the total number of its Senators and Representatives in Congress, while, per the Twenty-third Amendment ratified in 1961, Washington, D.C. casts the same number of electoral votes as the least-represented state, which is three. Also under Clause 2, the manner for choosing electors is determined by each state legislature, not directly by the federal government. Many state legislatures previously selected their electors directly, but over time all of them switched to using the popular vote to help determine electors, which persists today. Once chosen, electors generally cast their electoral votes for the candidate who won the plurality in their state, but at least 21 states do not have provisions that specifically address this behavior; those who vote in opposition to the plurality are known as faithless or unpledged electors. In modern times, faithless and unpledged electors have not affected the ultimate outcome of an election, so the results can generally be determined based on the state-by-state popular vote.
Presidential elections occur quadrennially with registered voters casting their ballots on Election Day, which since 1845 has been the first Tuesday after November 1. This date coincides with the general elections of various other federal, state, and local races; since local governments are responsible for managing elections, these races typically all appear on one ballot. The Electoral College electors then formally cast their electoral votes on the first Monday after December 12 at their respective state capitals. Congress then certifies the results in early January, and the presidential term begins on Inauguration Day, which since the passage of the Twentieth Amendment has been set at January 20.
The nomination process, consisting of the primary elections and caucuses and the nominating conventions, was not specified in the Constitution, but was developed over time by the states and political parties. These primary elections are generally held between January and June before the general election in November, while the nominating conventions are held in the summer. Though not codified by law, political parties also follow an indirect election process, where voters in the 50 U.S. states, Washington, D.C., and U.S. territories, cast ballots for a slate of delegates to a political party's nominating convention, who then in turn elect their party's presidential nominee. Each party may then choose a vice presidential running mate to join the ticket, which is either determined by choice of the nominee or by a second round of voting. Because of changes to national campaign finance laws since the 1970s regarding the disclosure of contributions for federal campaigns, presidential candidates f ...
