- Hertzsprung–Russell diagram (Wikipedia)
The Hertzsprung–Russell diagram (abbreviated as H–R diagram, HR diagram or HRD) is a scatter plot of stars showing the relationship between the stars’ absolute magnitudes or luminosities and their stellar classifications or effective temperatures. The diagram was created independently in 1911 by Ejnar Hertzsprung and by Henry Norris Russell in 1913, and represented a major step towards an understanding of stellar evolution.

Jurassic Park is a 1993 American science fiction action film directed by Steven Spielberg, produced by Kathleen Kennedy and Gerald R. Molen, and starring Sam Neill, Laura Dern, Jeff Goldblum, and Richard Attenborough. It is the first installment in the Jurassic Park franchise, and the first film in the original Jurassic Park trilogy, and is based on Michael Crichton’s 1990 novel of the same name, with a screenplay by Crichton and David Koepp. The film is set on the fictional island of Isla Nublar, off Central America’s Pacific Coast near Costa Rica, where a wealthy businessman John Hammond (Attenborough), and a team of genetic scientists have created a wildlife park of de-extinct dinosaurs. When industrial sabotage leads to a catastrophic shutdown of the park’s power facilities and security precautions, a small group of visitors, including Hammond’s grandchildren, struggle to survive and escape the now perilous island.
