Astro Boy (アストロボーイ・鉄腕アトム , Asutoro Bōi: Tetsuwan Atomu , lit.
 "Astro Boy: Mighty Atom") is a remake of the 1960s anime series of the same name created by Osamu Tezuka, which was produced by his company, Tezuka Productions, Sony Pictures Entertainment Japan, Dentsu, and Fuji Television network.
 It was also shown on Animax, who have broadcast the series across its respective networks worldwide, including Japan, Southeast Asia, South Asia, East Asia, and other regions.
 It was created to celebrate the birth date of Atom/Astro Boy (as well as the 40th anniversary of the original TV series).
 Under the original English name (instead of "Mighty Atom"), it kept the same classic art style as the original manga and anime, but was revisioned and modernized with more lush, high-quality, near-theatrical animation and visuals.
 It combined the playfulness of the early anime with the darker, more serious and dramatic Science fiction themes of the manga and the 1980 series.
 The anime broadcast in Japan on the same date as Atom's/Astro's birth in the manga (April 6, 2003) across Animax and Fuji Television.
 It was directed by Kazuya Konaka and written by Chiaki J. Konaka at the beginning of the series.
 Other writers included were Keiichi Hasegawa, Sadayuki Murai, Ai Ohta, Hirotoshi Kobayashi, Kenji Konuta, and Marc Handler, who was also executive story editor.
Ruler X (also Governor X) is the designation given by archaeologists to a pre-Columbian Maya ruler at the site of Rio Azul, whose name glyphs have otherwise not been satisfactorily deciphered.
 Ruler X is associated with Tomb 1 located in Structure C-1, where a mural inscription on the walls of the tomb carries the Long Count date of 8.19.1.9.13.
 This date, equivalent to September 27, 417 CE in the proleptic Gregorian calendar, has been interpreted as the birth date of this ruler.
Hippolytus or Hipolit (died c. 1027) was an early medieval archbishop of Gniezno.

Thomas Day Singleton (Birth date unknown – November 25, 1833) was a United States Representative from South Carolina.
 He was born near Kingstree, South Carolina but his birth date is unknown.
Smith was born in Macon, Georgia, likely into slavery, and he and his mother moved north in 1865.
 His birth date is given as 3 May 1860, but since he supposedly did not begin boxing until he was 19 and claimed the title in 1876, the birth year likely is spurious.
 Some sources cite 1869 as the year his boxing career began, and others 1879, which would have been three years after he claimed the championship.
