Isaac Asimov wrote a huge amount of science fiction over the years, and is known for many of his books such as the Empire Series, and most famously for the Foundation Series. The 3 main Foundation books were the ‘Foundation’, ‘Foundation and Empire’, and ‘Second Foundation’. It was later, in order to try and fill more details, that Asimov wrote more books for the Foundation, that include books that were both prequels and sequels. The last such book that he wrote was called ‘Forward the Foundation’, and was released in 1993, a year after Asimov died. Forward the Foundation was a sequel to ‘Prelude to Foundation’, carrying on with the story of Seldon’s search for how to develop the story of psycho-history.

In end of Prelude to the Foundation, Hari Seldon learns that Otto Demerzel, the powerful advisor to the Emperor ‘Cleon 1′ is actually a robot. He solicits Demerzel’s help for continuing the research into psychohistory, and Forward the Foundation continues into that effort, and is meant to show 4 different time stages in Seldon’s life. The novel starts 8 years from the end of Prelude to Foundation, as Seldon gets more involved in politics, helping Otto fight off attempts, and then moves a further 10 years down the line. Demerzel has vanished, and Seldon is now First Minister. However, after the assassination of Cleon 1, Seldon slowly starts losing his family members. His wife, Dors, is killed when trying to save him from an assassination attempt, his adopted son (the 12 year he met in Prelude to Foundation) dies elsewhere in another violent act, his assistant Yugo Amaryl dies of over-work, and it is left to Seldon and his grand-daughter Wanda to try and set a process in place to guide events when Seldon is no more. And so starts the story of 2 different Foundations, one of the physical base, and the other, a society of mentalics.

The ancient world was replete with fights and wars. Armies travelled long distances to fight, and warfare was often with massive casualties. One of the most famous kings of the ancient times was Xerxes The Great (Xerxes 1 of Persia), and he was involved with one of the most famous battles of historic times. This was the Battle of Thermopylae (wikipedia), where a much smaller contingent of Greek troops led by the King Leonidas I of Sparta fought till the end to hold off a much larger contingent (in the millions) of Persian troops led by King Xerxes. This was a battle that is part of modern strategy because of the use of terrain planning to level the odds of superior armed forces. King Leonidas was also fighting a rear-guard battle with his Spartan council to get them to support him over this battle, and he wanted to shame them with his valiant sacrifice to take action. In the end, he was betrayed by a traitor (Ephialtes) from within the Greek citizenry who revealed a small path that allowed the Persians to outflank the small Greek army.

The movie is a copy of a graphic comic-book style novel by Frank Miller (with the novel having the same name), and is not a re-telling of the actual battle. It is a heavily dramatized telling of the story, and hence also became controversial. In Iran, the movie was heavily criticized because the movie did not portray the Persian army and its King in a very positive light. The movie was directed by Zack Snyder. The movie was also shot in a novel way, with the characters acting against the background of bluescreens in a Studio (shot in a digital backlot technique). This was seen as very innovative and got a lot of publicity. The score of the movie was also controversial because after release, it started becoming clear that the score seemed to be heavily inspired from other movies, and was eventually acknowledged by Warner Bros. Pictures in an official statement.
The movie is about the conflict between King Leonidas of Sparta and the Persian Emperor Xerxes. Xerxes wants the Greeks to acknowledge their submission to him, something the proud Spartan king refuses to accept. Leonidas now anticipates war, and wants the support of the Council of Sparta and the priesthood (Ephor), but the Ephors do not support him (they have been bought over by the Persians). Without this support, Leonidas sets out with a small force to fight at a superior terrain where we can fight and hold off the numerically many times superior Persians. And hence the battle starts at Thermopylae. where Leonidas refuses riches by Xerxes and promises to make him bleed. The Spartans used their tight formations to defeat the many thrusts by the Persians, but look set for defeat when they are betrayed and a secret path is shown to the Persians.
In Sparta, the Queen is trying to rally support, and eventually manages to get the Council united in battle against the Persians. Eventually, the Spartans are beaten by the sheer force of the Persians, but by this time, the Greeks send in a force that has a much higher number of warriors. With memories of losses against 300 Spartans, the Persian army is low on morale, and eventually lose the final battle, the Battle of Plataea (Wikipedia).

El Cid, the legendary hero of Spain was a real person named Don Rodrigo Diaz de Bivar ((c. 1040, Vivar, near Burgos – July 10, 1099, Valencia)). He lived around 1035 A.D. Although he spent much of his time fighting on the side of the Moors, he became identified as the best incarnation of the true Castilian Christian spirit. His name came from the Arabic “sayyid” meaning “lord” or “chief.” He was a nobleman, who was educated in the royal court of Castile, and was one of the leading warriors of Alfonso VI against the Moors. He is considered the national hero of Spain.
As is expected, a movie made on such a hero is always made more romantic than reality, with acts of heroism and valor magnified, and when the movie has such actors such as Charlton Heston and Sophia Loren, the movie seems much more romanticized than the original. The movie was released in 1961 and earned 3 Oscar nominations, but was unable to win any Oscars.

The movie was directed by Anthony Mann, and was shot primarily on location in Spain (including the historic castles of Belmonte (Cuenca) and Peñíscola (Castellón)), with a smaller number of scenes being shot in Rome. The movie used real swords during the shooting, so you would expect that the action scenes needed a much better control and thorough safety measures.
El Cid was part of an aristocratic family, but not very powerful or high in the Spanish royal court. However, he became famous as a man who was a warrior at the same time as he was a peacemaker, willing to spare enemies if they swore their allegiance to his king. This was a time when there were many royals, with many of these royals fighting for power, and fighting for the throne. And this was also a time when the Moors were fighting for gaining space in Spain, in their quest to introduce the power of Islam inside Spain.
He was to fight back charges of treason, and eventually loses favor at the royal court, becoming a mercenary when his king Alfonso abandons him. He even fights on the side of the Moors, but eventually comes back to support his king when he is called back. He also came to command much more influence among the common people, earning their respect, and forming his own army composed of both Christians and Moors, forming his own fiefdom comprising the city of Valencia and its neighboring regions.
The book had some great scenes, such as the fight between two single warriors to get control of the city, which was a great fight. Shooting on location imparted some incredible majesty and splendor to the movie.

To read a science book can be dreary or boring; or it can be enlightening, imparting a wonderful education. It all depends on the author, and Carl Sagan was a wonderful author in this regard. He explains the concepts and ideas thoroughly, dosing an imparting of humour into the whole explanation and making it actually fun to read. Evolution is a heavy topic, and is also a political hot potato in the United States, where many bible groups believe that God (or intelligent design) is the creator of all life in the world, and more detrimentally to science, evolution is just a theory with no proof, a postulation by atheist scientists who do not recognize the importance of a supreme being in the whole aspect of creation.

Carl Sagan does not go against religion, he is more for the use of common sense and logic, backed by a scientific bent of mind, which looks for proof and theories that can explain life and its mysteries. So, Carl Sagan takes the theory of evolution, from the primordial single cell creatures to the age of reptiles to the evolution of highly intelligent species such as humans. He also takes on the human fear of reptiles, suggesting this fear to be based on early human’s struggle against predators. Sagan also does a lot of detailing on subjects such as the search for a quantitative way of measuring intelligence (using the brain to body mass ratio), the evolution and structure of the brain, why do humans dream, etc.
The book won a Pulitzer Prize, and was a continuation of the Jacob Bronowski Memorial Lecture in Natural Philosophy which Sagan gave at the University of Toronto. The chapters of the book are:
