310. Humanizing History - 赋历史以人性,访谈《奥本海默传》作者 Kai Bird

Blow Your Mind (BYM S02)

Our guest is historian and journalist Kai Bird, author of the book American Prometheus, for which he won the Pulitzer Prize. In 2023, the book was adapted to the biographical film Oppenheimer, directed by Christopher Nolan. In this interview, we covered - Oppenheimer's life, from leading scientific research at the Manhattan Project, to the security hearing after the war. - What lessons and warnings we should take from Oppenheimer's life. -Kai's experience writing the book, in collaboration with Martin Sherwin. -How did Kai become a biographer, and how he choose his subjects. In Chinese mythology, there too is a Prometheus-like figure, who taught the Chinese the use of fire. His name was Sui-ren (燧人). But there were three differences between Sui-ren and Prometheus: 1) Sui-ren was human, not a divine being like Prometheus; 2) Sui-ren discovered fire-making on his own, and 3) he was revered as a great teacher and leader for teaching people the use of fire. At the risk of over psycho-analyzing it, I can't help wondering how these ancient myths have shaped the diverging views on the relationship between Nature and human, scientific progress, and technology risks. 00:00 - guest introduction 00:57 - Oppenheimer's life before the Manhattan Project 09:44 - the Manhattan Project 22:54 - after the war; security hearing 36:10 - what makes for a good story arc 39:07 - collaborating with Martin Sherwin 43:53 - Hollywood came knocking 45:33 - the Nolan film 53:48 - becoming a biographer 56:32 - choosing subjects 63:05 - current project Blow Your Mind (BYM) is a Chinese and English bilingual podcast that covers a broad range of topics. Some of the recurring themes are: technology, economics, story-telling, history, entrepreneurship, creativity and mathematics. Past show guests include film-makers, authors, performing artists and AI researchers. Email: [email protected] ====== 本期嘉宾是历史学家兼记者凯·伯德(Kai Bird)。他是普利策奖得主, American Prometheus (中译本《奥本海默转》)作者。在2023年,这本书被改编成了传记电影《奥本海默》,由克里斯托弗·诺兰(Christopher Nolan)执导。 在这次采访中,我们讨论了: 奥本海默的一生,从领导曼哈顿计划的科研,到战后的安全听证会。 我们应该从奥本海默的生活中汲取哪些教训和警示。 凯撰写这本书的经历,以及与马丁·谢尔温(Martin Sherwin)的合作。 凯是如何成为一名传记作家的,以及他是如何选择传记人物。 在中国神话中,也有一个类似普罗米修斯的人物,他教会了人们使用火。他的名字是燧人。但燧人与普罗米修斯有三个不同之处:1) 燧人是人,不像普罗米修斯那样是神;2) 燧人是自己发明了钻木取火;3) 他因教人们使用火而被尊为老师和领袖。 这可能是过度分析了,但我不禁猜想这些古老的神话是否深刻影响了对自然与人类、科学进步和技术风险之间的不同看法。 00:00 - 嘉宾介绍 00:57 - 曼哈顿计划前的奥本海默 09:44 - 曼哈顿计划 22:54 - 安全听证会和战后奥本海默的生活 36:10 - 如何算作一个好故事线 39:07 - 与马丁·谢尔温的合作 43:53 - 好莱坞来敲门 45:33 - 诺兰执导 53:48 - 成为传记作家之路 56:32 - 人物选择 63:05 - Kai 的下一个传记选题 如果你对核物理以及原子弹诞生过程感兴趣,除了《奥本海默传》之外,还推荐这部《横空出世》。这是一本更为详尽的历史书,讲述了科学史上群星闪耀的半个世纪,两次世界大战,以及最终原子弹的诞生。此书也获得包括普利策奖在内的多项出版界大奖。 Blow Your Mind (BYM) 是一档中英双语播客,涉猎广泛的主题,包括科技、经济、讲故事、历史、创业、创造力和数学。过往的嘉宾包括电影制作人、作家、表演艺术家和AI科学家。 Email: bymclub(a)outlook.com

308. AI Safety and Explainability 人工智能安全,访谈图灵奖得主Prof. Sifakis

Blow Your Mind (BYM S02)

本期嘉宾是 Joseph Sifakis 教授。Sifakis 教授是知名的计算机科学家,在2012年获得达芬奇奖,并在2007年获得图灵奖。他的书作 Understanding and Changing the World 中译版《理解和改变世界》已经出版。 在这期播客中,我们讨论了多个话题,涉及计算机科学、哲学与AI及 autonomous system (自治系统) 对社会的影响。主要观点包括: -写书的缘起,来自 Prof. Sifakis 对哲学问题的兴趣和他觉得现有哲学文献的不足,特别是关于知识和信息概念有所不足。 -AI与可解释性:知识的本质。强调AI生成的知识缺乏可解释性,而通过科学方法产生的知识具备可解释性。AI与科学方法相比,无法提供强有力的保证。 -自治系统(autonomous systems)的测试与安全:AI系统的安全性是个大挑战,如自动驾驶,现有的系统缺乏可解释模型,而实践测试又有局限性。 -AI的伦理与社会影响:将AI投入实际应用的伦理考量,特别是对人类责任和决策的影响。 -AI在未来技术中的角色:AI在未来可应用于系统监测,以及与传统控制系统集成以提高可靠性和安全性。混合系统 (hybrid system)的优势和挑战。 -Prof. Sifakis 的职业生涯和研究兴趣:职业轨迹覆盖模型检查的理论研究到系统设计的实际应用,以及他是如何选择研究课题。 -AI在教育中的应用:AI工具(如聊天机器人)对儿童发展和学习的影响,倡导在教育中节制地使用技术。 -对大众的建议:负责任地使用AI,辩证评估AI产出的内容,维护人类的价值观和责任。 Blow Your Mind (BYM) 是一档中英双语播客,涉猎广泛的主题,包括科技、经济、讲故事、历史、创业、创造力和数学。过往的嘉宾包括电影制作人、作家、表演艺术家和AI科学家。 ====== Our guest is esteemed computer scientist Professor Joseph Sifakis.

306. 消失的法老 Horizon of Khufu - 令人期待的VR技术

Blow Your Mind (BYM S02)

We, the show hosts, went to see a virtual reality (VR) show "Horizon of Khufu" (in Chinese: 消失的法老). In this episode we discussed our thoughts on the show and VR technology. After being around for decades, VR seems finally within reach of wide consumer application, and this show is proof. While this show still has rough edges (abrupt scene transitions, little interactivity), one can extrapolate the potential, and anticipate much better works in just a couple of years. In terms of technology maturity, we are quite beyond the equivalent of The Great Train Robbery (1903). In the podcast we also talked about a related work "we met in virtual reality" (2022) -- a documentary shot entirely in VR. One of the show hosts, feng, was surprised at how expressive the avatars have become. The avatars are so good at delivering fine gestures that people can use sign language in VR. feng shared this moment: the day after seeing the show, I was sitting outside having a cup of coffee and taking in the warmth of the afternoon sun. right then, for a brief moment, i couldn't quite tell if this is VR or reality. the sun light streaking down between the tree leaves felt real enough, but barely more so than yesterday when I was perching at the top of the great Khufu pyramid in VR. The potential for a new form of storytelling is exciting. If the development of the film and TV industry can be of reference, the next couple decades will be a time when we figure out the grammar for this new medium, and its strengths. Shows like the Horizon of Khufu is an excellent early attempt. It also clearly carries the legacies from film-making and video games. 消失的法老, website: https://horizonkheops.com/en/ we met in virtual reality, imdb link: https://www.imdb.com/title/tt16378482/reference/

305. 如何养育一个「未来」的孩子| 做个“差不多”的爸妈

Blow Your Mind (BYM S02)

长效自护,领熠未来。感谢爱他美旗下顶配「领熠」对这一期节目的支持。这一期我们征集了听众关于育儿话题的问题来回答和分享。有了宝宝之后,我们花了很多时间学习“如何做父母”,并从身边做爸妈的朋友那里寻求经验和支持。对于很多问题感同身受,也有很多体验想要分享。 这一期中,我们主要回答了几个听众的提问: “怎么培养孩子的韧性和处理能力?怎么把握“育儿里的度”,不要太严使孩子叛逆、不要太松惹来麻烦?” “如何能够在保证孩子身心健康的前提下,协助起全面发展,同时家长还能保持不内卷不焦虑?” 育儿方式对孩子的未来有怎样的影响?什么是“对的教育”? 如果在幼年时期家长因为工作没有办法长期带娃,如何弥补缺失?怎么平衡工作和陪孩子? 当了爸妈之后对健康的认知有了什么改变吗? 我们也分享了一些我们自己在遇到育儿问题时候,会使用的方法。如何找资料。我一直觉得做新手父母这个阶段,人们不得不重新面对自己是谁这个问题。在养育孩子的过程中,人不得不面对自己的各种议题、要在每一个育儿的时刻,选择自己想要做什么样的父母、选择和自己的孩子建立怎样的关系。育儿中其实大多数的感受,无论是喜悦还是难过,大多数是关于自我的。 希望父母们都有充分的参与育儿的意愿,有感受幸福的能力,有一些自由感,做“差不多”的父母。 再次感谢「爱他美领熠」的支持。爱他美旗下顶配「领熠」,拥有百亿源自健康宝宝肚肚的原生活菌和益生元,菌元协同,组成专利乳黄金熠生链,助力宝宝快速建立健康的肠道菌群微生态,让宝宝拥有受益一生的自护力 也欢迎大家在留言中分享,你眼中的「未来式育儿」是什么?我们将在评论区的留言中,选出5位听众朋友,每人赠送 300g 爱他美领熠3段奶粉一罐。

302. 你拥有令天使羡慕的生活|Kevin Kelly 新书《宝贵的人生建议》

Blow Your Mind (BYM S02)

本期 BYM 是 FENG哥+孟岩+嘉宾 Kevin Kelly 录制的一期节目。Kevin Kelly 是《失控》作者,Wired(《连线》杂志)创始主编。这次我们聊了: - Kelly 的新书《宝贵的人生建议》;如何破解 “道理都懂,但仍然过不好生活” - Kelly 辍学后在亚洲的背包旅行;为什么他说 “这是我做的最好决定之一” - "The Silver Cord"是 Kelly 参与创作的一部科幻+奇幻的 graphic novel。其故事背景:天使羡慕人类的生活,不惜化身机器人来到人间 -AI 给创作带来的影响,以及 Hofstadter (GEB 作者)。Hofstadter 最近撰文表达了 AI 冲击下,对人类未来的悲观。但 Kelly 却对未来充满期待和乐观。节目最后,他分享了他的原因。 Kelly 参与过很多有趣的项目。本期节目内容也因此十分丰富。在所谈到的作品中,最打动 FENG哥的是: The Silver Cord。从古到今,东西方的故事中,“羡慕人类的生活” 是反复出现的主题。东方有仙女思凡、狐狸成精,西方有匹诺曹。似乎人类的生活是一个令人羡慕,并且需要付出千年修炼,经历诚实勇敢的考验,才能获得的礼物。 The Silver Cord 是对这主题的又一次诠释:天使们羡慕人类,又痛心于人类并不珍惜所拥有的生活,将生命蹉跎与无聊的事情中。最后天使不惜化为机器人以 “换成肉身”。 正在收听本期 BYM 的你,已经幸运的拥有令天使羡慕的生活。好好把握和享受吧!(或许 Kelly 的新书能够给你启发。) 谢谢中信出版提供了《宝贵的人生建议》全网最低价,链接:https://item.jd.com/13863267.html BYM 邮箱:bymclub(a)outlook.com
