Tool

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.

History

Anthropologists believe that the use of tools was an important step in the evolution of mankind. Because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.

Stone artifacts only date back to about 2.5 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago.

Luiz Inácio Lula da Silva

Luíz Inácio Lula da Silva (Portuguese: [luˈiz iˈnasju ˈlulɐ dɐ ˈsiwvɐ]; born 27 October 1945), known simply as Lula, is a Brazilian politician who served as President of Brazil from 1 January 2003 to 1 January 2011. He is a founding member of the Workers' Party (PT – Partido dos Trabalhadores) and ran for president three times unsuccessfully, first in the 1989 election, then again in 1994 and 1998. Lula achieved victory in the 2002 election, and was inaugurated as president on 1 January 2003. In the 2006 election he was elected for a second term as president, which ended on 1 January 2011. Succeeded by his former Chief of Staff, Dilma Rousseff, he left an enduring mark on Brazilian politics in the form of Lulism.

He is often regarded as one of the most popular politicians in the history of Brazil and, at the time of his mandate, one of the most popular in the world. Social programs like Bolsa Família and Fome Zero are hallmarks of his time in office. Lula played a prominent role in recent international relations developments, including the nuclear program of Iran and global warming, and was described as "a man with audacious ambitions to alter the balance of power among nations." He was featured in Time's The 100 Most Influential People in the World for 2010, and has been called "the most successful politician of his time."
