一 | FTX founder Sam Bankman-Fried believed in utilitarianism and thought rules against lying or stealing inhibited his ability to maximize the greatest benefit for the most people, his former girlfriend and co-worker testified Wednesday at his federal fraud trial."He didn't think rules like 'don't lie' or 'don't steal' fit into that framework," Caroline Ellison, Bankman-Fried's on-again, off-again girlfriend, said.She said Bankman-Fried's belief caused her to accept behavior she recognized as wrong."I think it made me more willing to do things like lie or steal over time. When I started working at Alameda, I don't think I would have believed if you told me I would be sending false balance sheets or taking customer money," Ellison, who served as CEO of Alameda Research, said. "Over time it became something I was more comfortable with."Bankman-Fried faces seven counts of fraud, conspiracy and money laundering centered on his alleged use of customer deposits on the crypto trading platform FTX to cover losses at his hedge fund, Alameda Research, and to buy lavish real estate, among other personal expenses.On the witness stand for a second day Wednesday, Ellison walked the jury through Alameda balance sheets which, by October 2022, showed Bankman-Fried's private hedge fund owed FTX customers nearly $14 billion."We had a lot of risk on and we owed a lot of money to FTX customers," Ellison said. "We had no way to repay it."She said Bankman-Fried thought about trying to raise money from Mohammed bin Salman, the Saudi crown prince, or by selling shares in FTX, which would collapse in bankruptcy the following month, in November 2022."I was in a state of dread. I was thinking, worrying, imagining every day what would happen if people tried to withdraw too much money at one time," she said. "I was imagining all the FTX customers who we worked with who would get hurt by this."To shore up Alameda's precarious financial position Bankman-Fried told Ellison to repay Alameda's loans with money it borrowed surreptitiously from FTX customers, she testified Wednesday."He directed me to continue repaying Alameda's loans," Ellison said."How?" prosecutor Danielle Sassoon asked."By taking money from FTX customer funds," she replied.When Sassoon asked her if she knew it was wrong, Ellison replied, "Yeah I thought it was wrong," but continued to do it because "Sam told me to."By that point, Alameda had taken about $10 billion from FTX and Ellison said she worried its lender, Genesis, would find out."We had been borrowing increasing amounts of money from FTX customers and I didn't want Genesis to know that," Ellison said. "I didn't want Genesis or others to know that Alameda was borrowing a lot of money from FTX."Ellison said Bankman-Fried cautioned her against putting anything in writing, once telling her, "Anything we put on Slack should be something we're comfortable seeing in The New York Times."Ellison also described a "large bribe to Chinese government officials to get some of our trading accounts unlocked." Alameda had two trading accounts worth about a billion dollars on exchanges based in China, which were both frozen in 2021 as part of a Chinese government investigation into money laundering.It was a substantial amount of Alameda's trading capital at the time and Ellison accused Bankman-Fried of saying "that we should send the cryptocurrency transfers" equaling about $100 million.。1月12日消息1月11日，英国皇家学会发表讣告。英国著名数学家迈克尔·阿提亚爵士于当日去世，享年89岁。
二 | 阿尔泰爵士于2018年9月宣布，他已经证明了黎曼猜想，这在数学界引起了轰动。作为英国数学的“教父”，阿泰爵士是菲尔兹奖和亚伯奖的双料得主。虽然阿尔泰爵士在海德堡奖得主论坛上提出的黎曼猜想尚未得到广泛认可，但阿尔泰对数学，特别是代数几何作出了贡献。杰出贡献，被誉为当代最伟大的数学家之一。阿泰纳爵士曾任英国皇家学会主席、剑桥大学三位一体学院院长、爱丁堡皇家学会主席，并当选为多国科学院外国院士。他的早期工作主要集中在代数几何领域。与isado singer合作证明的atia-singer指数定理被认为是20世纪最重要的数学成果之一。自20世纪70年代以来，他的兴趣转向了规范场理论。近30年来，量子场论和弦理论对低维拓扑和无限维流形几何的研究受到了极大的启发。他是这个新兴领域的主要倡导者之一。
三 | 小科学普及：黎曼的猜想是什么？黎曼猜想是关于黎曼函数零点分布的一种猜想。这是里曼在1859年提出的。
四 | 这个猜想是世界上七个主要的数学问题，由克里数学研究所奖励。这七个世界问题分别是NP完全问题、霍奇猜想、庞加莱猜想、黎曼猜想、杨米尔斯存在与质量差距、纳维尔-斯托克方程和BSD猜想。
五 | 如果阿提亚爵士的证据没有问题，这七个问题将得到一百万美元的奖励。他将得到一百万美元的奖励。黎曼认为，素数在所有自然数中的频率都与一个复函数密切相关，也就是说，u（s）=1 1/2s 1/3s 1/4s，称为黎曼齐塔函数。黎曼猜想认为所有素数都可以表示为一个函数。_（s）=0位于一条垂直线上，称为黎曼猜想。一百多年来，无数人试图证明黎曼的猜想，但到目前为止，还没有人能达到顶峰。1900年，德国著名数学家希尔伯特在巴黎国际数学家会议上提出了20世纪数学家们应该解决的23个数学问题，即著名的“希尔伯特23问题”，被认为是20世纪数学的制高点，包括里曼C。
