Norman Zada

Zada obtained a PhD in Operations Research at the University of California, Berkeley and worked at IBM. He was an adjunct mathematics professor at Stanford University, Columbia University, UCLA and University of California, Irvine, writing articles on applied mathematics as well as the 2020 book ''Hold'em Poker Super Strategy. and the 1974 book Winning Poker Systems''. After teaching, he won both backgammon and sports handicapping championships and later became a money manager. In the 1980s he ran a number of financial competitions, including the United States Investing Championship. Zada made headlines in 1996 when he offered $400,000 for anyone successfully refuting his claim that balancing the United States federal budget over a multi-year period without an accompanying substantial trade surplus would be effectively mathematically impossible. ==Perfect 10 magazine==

Zada launched Perfect 10 magazine, an adult magazine focusing on women without cosmetic surgery, after a friend was rejected from Playboy magazine because her proportions did not fit the magazine's tastes. He estimates losing approximately $46 million on Perfect 10 since 1996, when the magazine was first published. It has been claimed that these losses have been borne by Zada because of the deductions this allows against gains made in the money market. The company also sued Giganews, Inc. It has been claimed that Zada spends minimal time – 40 to 50 hours a year – creating content for the site, but "8 hours a day, 365 days a year" on litigation, leading some to call Perfect 10 little more than a copyright troll – by 2015, the company had filed 20 to 30 lawsuits. ==Personal life==

Zada is the son of Lotfi A. Zadeh, a computer scientist who coined the term fuzzy logic. Zada at one time owned a large mansion in Beverly Park that he sold in 2010 for $16.5 million. Zada apparently uses the name "Dr. Norman Zadeh" in connection with the United States Investing Championship. In a press release for the competition issued on December 28, 2018, Zada is referred to by that name. ==References==
