while more conventional references are made in Ludacris and Jermaine Dupri's popular single "Welcome to Atlanta". The 2003 Ang Lee-directed Hulk film saw discussion of the character's appeal to Asian Americans. The Taiwanese-born Ang Lee commented on the "subcurrent of repression" that underscored the character of The Hulk, and how that mirrored his own experience: "Growing up, my artistic leanings were always repressed—there was always pressure to do something 'useful,' like being a doctor." Jeff Yang, writing for the San Francisco Chronicle, extended this self-identification to Asian American culture, arguing that "the passive-aggressive streak runs deep among Asian Americans—especially those who have entered creative careers, often against their parents' wishes." There have been explorations about the real-world possibility of Hulk's gamma-radiation-based origin. In The Science of Superheroes, Lois Grest and Robert Weinberg examined Hulk's powers, explaining the scientific flaws in them. Most notably, they point out that the level of gamma radiation Banner is exposed to at the initial blast would induce radiation sickness and kill him, or if not, create significant cancer risks for Banner, because hard radiation strips cells of their ability to function. They go on to offer up an alternate origin, in which a Hulk might be created by biological experimentation with adrenal glands and GFP. Charles Q. Choi from LiveScience.com further explains that, unlike the Hulk, gamma rays are not green; existing as they do beyond the visible spectrum, gamma rays have no color at all that we can describe. He also explains that gamma rays are so powerful (the most powerful form of electromagnetic radiation and 10,000 times more powerful than visible light) that they can even convert energy into matter – a possible explanation for the increased mass that Bruce Banner takes on during transformations. "Just as the Incredible Hulk 'is the strongest one there is,' as he says himself, so too are gamma-ray bursts the most powerful explosions known." Other Marvel Comics characters called the Hulk Prior to the debut of the Hulk in May 1962, Marvel had earlier monster characters that used the name the "Hulk", but had no direct relation. In Strange Tales #75 (June 1960), Albert Poole built an armor he called the Hulk. In modern-day reprints, the character's name was changed to Grutan. In Journey into Mystery #62 (Nov. 1960) was Xemnu the Living Hulk, a huge, furry alien monster went by the name of the Hulk. Coincidentally,
