In a conversation between the Marstons and Byrne, Byrne quotes her aunt: “A woman must not be told how to use her freedom she must find out for herself. They also do this to hide their own insecurities and self-doubt.īyrne and Diana share other similarities. At times both Byrne and Diana appear to use their physical beauty to mask their abilities and appear less threatening to men. Her assessment that Byrne has to be nice to men she has no sexual interest in is based on Byrne’s fear of being labeled a “slut.” Diana, similarly, is a gorgeous Amazon who people cannot stop looking at, but no one suspects her hidden depths as a result. She recognizes that Byrne has intelligence and value beyond just being beautiful, but she also knows that men only see her physically and make their judgment based on this. In conversation with her husband, Holloway comments that Byrne’s beauty is a burden. In this case, Minerva’s lack of recognition stems from her looks: her mild-mannered appearance and meek personality contrast with the more dominant ideals of the time. In the same way, we meet Barbara Minerva as a new geologist who is unrecognized by her peers despite her work. We learn that Holloway is unhappy that she can only be granted a doctorate from Radcliffe and not the more prestigious Harvard because of her gender despite the two schools being of equal academic rigor. The film begins with Marston as a professor at Radcliffe College, the female-associated institution of the male-only Harvard. To begin, Robinson posits that the lives of Marston, Holloway, and Byrne were dictated by DISC theory. But the correlation between Robinson and Jenkins’ films appears to be all the more curious. Jenkins herself has spoken at length in documentaries about her admiration for Marston’s work and his progressive ideals that made Diana who she is. Robinson’s film suggests that Marston pulled much from his life, along with those of his wife and lover, to create the world of Wonder Woman. Diana wishes for her lost love Steve Trevor (Chris Pine) to come back to life, while her colleague and new friend Barbara Minerva (Kristen Wiig) wishes to be more like Diana. Her life is made difficult when powerful businessman Max Lord (Pedro Pascal) steals a wish-granting stone that gives you your heart’s desire but takes something from you in return. Meanwhile, Patty Jenkins’ 2020 blockbuster sequel Wonder Woman 1984 follows the titular hero living in ‘80s Washington, D.C., under the alias Diana Prince (Gal Gadot), curating history exhibits for the Smithsonian and occasionally stepping up as a superhero when injustice calls for it. The comic books were Marston’s way of injecting his psychological theories into people’s minds via the ever-popular medium of comic books. According to Robinson’s film, this was the catalyst for creating Wonder Woman. Along the way, Marston and Holloway hire Olive Byrne (Bella Heathcote) as an assistant before they both discover feelings for her, learn that she reciprocates those feelings, and begin a polyamorous relationship. Marston and his wife Elizabeth Holloway Marston (Rebecca Hall) also worked on perfecting the systolic blood pressure test, a precursor to the polygraph lie detector test. Marston’s theory follows his belief that people are happier when they are willingly submissive to authority, that the four “stages” bring about an inner peace by the end. His main area of concern was the DISC theory, a behavioural theory that dictated that there were four personality traits that people obeyed: Dominance, Inducement, Submission, and Compliance. Robinson’s film posits that William Moulton Marston (as played by Luke Evans) was a radical feminist academic. Its release coincided with the first major film outing for the character in Patty Jenkins’ groundbreaking action blockbuster Wonder Woman. The origin of Wonder Woman was depicted in the 2017 film Professor Marston and the Wonder Women by writer-director Angela Robinson. Few know that Superman was the creation of nerdy friends Jerry Siegel and Joe Shuster, or that behind Batman’s cowl was a bitter dispute between writer Bob Kane and artist Bill Finger over who should receive credit for the character’s creation.Įven fewer, though, would know that Wonder Woman, perhaps the most famous female comic book character, was created in strange and radical surroundings. For other comic book writers, this isn’t the case. Not a person alive today doesn’t cheer when they see him on screen. Lee is perhaps the only household name in comic books, trademarked by his mustache, two-tone hair, and big sunglasses. Stan Lee, ever the showman, made himself so inseparable from his comic book creations that no film was complete without a gracious and knowing cameo from the man himself. The game is based on an enhanced version of the IW engine developed by Infinity Ward with increased development on audio and visual effects. A new feature to the series was the addition of a cooperative mode, which supports up to two players locally and four players online, as well as the introduction of the Zombies mode.ĭevelopment for World at War took two years and began after the release of Treyarch's previous title, Call of Duty 3, which was also set in World War II and was their first title they developed for the series. The game also contains downloadable content called "map packs", which can be purchased online. Vehicles, in the form of tanks, that players can control appear on certain multiplayer maps. The multiplayer component of the game contains various game modes and a leveling system that allows the player to unlock additional weapons and rewards as they progress, similar to Call of Duty 4 and repeated in many following Call of Duty entries. Miller, US Navy Petty Officer Locke and Red Army soldier Private Dimitri Petrenko, and is based on several historical battles. It is told from the perspectives of Marine Raider Private C. The narrative for the campaign mode focuses on the Pacific and Eastern Front theaters of World War II, involving the United States, Empire of Japan, Soviet Union, and Nazi Germany. A Windows Mobile version was also made available by Glu Mobile. It was the first game in the series to feature the zombies mode featured in later sequels. World at War received ports featuring different storyline versions, while remaining in the World War II setting, for the Nintendo DS and PlayStation 2. The game is also the first title in the Black Ops story line. It is the fifth main installment of the Call of Duty series and returns the setting to World War II.

The missions themselves are great, I played through the first one in the demo and was glad to see I could pick up with the second after purchasing the full game. I've never played Commandos or Desperados, but I really love Japan in all regards and enjoy strategy. This game really came out of the blue for me as well. I'm actually really liking the story as it develops, too. The characters are really great (I'm only 3 missions in) and voiced very well. PSA 2: Play with Japanese audio and subtitles.

1/31/2024 0 Comments Xsection 8 applicationParticles like neutrons are actually quantum clouds that pass through each other or interact with an energy-dependent probability - the likelihood of collision has little to do with a solid, cross-sectional area. It is as though the neutrons change the area of their cross section mid-flight. But soon, disparities arose: Neutrons are more likely to collide with certain nuclei when they are moving slowly than when they are fast. Rutherford’s experiment, which collided alpha particles and gold nuclei in 1911, revealed that nuclei are much smaller than previously supposed. When Xerxes darkened the sky with arrows at the Battle of Thermopylae, the probability of getting hit by an arrow was very high.Įarly collision experiments were intended to measure the size of particles from their collision rate. The collision probability for a cloud of projectiles is simply the ratio of area covered by them to the total area of the cloud. Subatomic particles are so small that aiming individual particles at each other is out of the question - the best anyone can do is to shoot a lot of them in the same general area. When marbles or billiard balls are rolled at each other, the probability that they will collide is proportional to the size of the balls, unless they are precisely aimed. In the early days of particle physics, particles were thought to be tiny indestructible balls. How did particle physicists come to use “cross section” in such a strange way? It’s a long story. For instance, when CMS physicists measure the “proton-proton to top-antitop” cross section, they are counting how many top-antitop pairs were created when a given number of protons were fired at each other. A particle physicist might use the word this way, but more often it is used to mean the probability that two particles will collide and react in a certain way. In everyday speech, “cross section” refers to a slice of an object. The term “cross section” is a berry of particle physics - its technical meaning is very different from the common usage. Talking to a botanist friend of mine, I learned that tomatoes are berries, but strawberries are not - the scientific meaning of a berry has more to do with the reproductive structures of the plant than the way it tastes. Sometimes, everyday words are co-opted by scientists and used as technical terms. |
