The charge of an antiparticle equals that of the corresponding particle, but with opposite sign. Quarks have fractional charges of either â 1â3 or + 2â3, but free-standing quarks have never been observed (the theoretical reason for this fact is asymptotic freedom).
Michelangelo di Lodovico Buonarroti Simoni (6 March 1475 â 18 February 1564) (. [mikeËlandÊelo]), was an Italian sculptor, painter, architect, poet, and engineer of the High Renaissance who exerted an unparalleled influence on the development of Western art.Considered as the greatest living artist in his lifetime, he has since been held as one of the greatest artists of all time.ichelangelo, with Leonardo da Vinci and Raphael, is one of the three giants of the Florentine High Renaissance. Although their names are often cited together, Michelangelo was younger than Leonardo by 23 years, and older than Raphael by eight.
Born 13 years after da Vinci, Michelangelo followed in his footsteps as a Renaissance man. He was an accomplished artist, poet, architect, and engineer. His best-known work is probably the sculpture David, which was completed in the opening years of the 16th century.
