当代物理学素养
The eternal mystery of the world is its comprehensibility. – Albert Einstein
世界为什么有规律可寻,而非混沌无规?一个混沌的宇宙大概无法诞生生命,乃至演化出试图理解其自身的智慧生命,也就无法提出这样的问题,即所谓的“人择原理”。可为什么人类可以理解这些规律?组成个体的细胞也可以理解其所存在与构成的个人本身吗?作为宇宙而言,又为什么要演化出试图理解其自身的智慧生命?宇宙存在的意义是什么?人类或许可以通过创造生命与智慧,乃至新的地球,来理解我们自己的存在,但我们要如何理解宇宙的存在?

时间之矢(Entropy)、全息原理(Information)、量子纠缠(Entanglement)
梅森哲讲座是康奈尔大学邀请知名学术或公众人物所做的系列讲座,由Hiram Messenger于1924创立。最初形式为讲授者一年讲12节系列课程,现在则演变为在一学期内讲授3或6节系列课程。最出名的是费曼在1964所讲的7节课程:物理定律的本性(The Character of Physical Law),讲座内容后来成书出版。

- It from Qubit(IfQ)
万物源于量子比特(It From Qubit)是由西蒙斯基金于2015年起所组织的集合量子物理、引力理论与量子信息等领域科学家的跨学科合作项目。项目名称源自著名理论物理学家约翰·惠勒所提出的“万物源于比特(It from Bit)”的猜想,认为信息才是物质世界的基础,粒子或场由于观测者的参与才实现其存在(“参与性宇宙”)。

- Do black holes have interiors? Does the universe exist outside our horizon?
- What is the information-theoretic structure of quantum field theories?
- Can quantum computers simulate all physical phenomena?
- How does quantum information flow in time?
It from bit. Otherwise put, every it — every particle, every field of force, even the space-time continuum itself — derives its function, its meaning, its very existence entirely — even if in some contexts indirectly — from the apparatus-elicited answers to yes-or-no questions, binary choices, bits. It from bit symbolizes the idea that every item of the physical world has at bottom — a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe.
Information, Physics, Quantum: The Search for Links – John Wheeler(1989)
We are participators in bringing into being not only the near and here but the far away and long ago. We are in this sense, participators in bringing about something of the universe in the distant past and if we have one explanation for what’s happening in the distant past why should we need more?
- Black Hole Initiative(BHI)
黑洞倡议(Black Hole Initiative)是由邓普顿基金会于2016年在哈佛大学组织的综合的跨学科黑洞研究项目,集合了天文、数学、物理、哲学各学科的领军人物,如视界面望远镜(EHT)项目负责人Sheperd Doeleman、知名数学家丘成桐等。
If determinism — the predictability of the universe — breaks down in black holes, it could break down in other situations. Even worse, if determinism breaks down, we can’t be sure of our past history either. The history books and our memories could just be illusions. It is the past that tells us who we are. Without it, we lose our identity.
— Stephen Hawking, BHI Inauguration(2016)
Theoretical Minimum
理论底限(The Theoretical Minimum)系列是由弦论创始人之一、著名理论物理学家莱昂纳德·萨斯坎德(Leonard Susskind)在斯坦福大学所讲授的继续教育课程。主要针对了解基本代数及分析知识,对理论物理感兴趣却又没有机会学习的人,讲述理解现代物理所需的最低限度的物理及数学知识,用于填补深度不足的科普与艰深晦涩的教材之间的空白。系列共包括6门核心课程及一系列补充课程,内容涵盖经典分析力学、量子力学、狭义相对论、广义相对论、宇宙学、统计物理、粒子物理、弦论、量子纠缠,此外还配套发行有相关书籍。
