嘿!你的大脑是不是也渴望一场说走就走的“知识自助餐”?你是不是也想把那些晦涩难懂的科学原理,变成像嗑瓜子一样轻松过瘾的碎片?

欢迎来到 《知识“嗑”学家》!我是金卫,你的专属知识“嗑”学官。

在这个充满好奇心的实验室里,我们不讲教科书,不背枯燥定义。我将化身你的“科学常识说明书”,帮你把:

生活中的小疑问(为什么眼睛会“看到”星星?蚊子为什么总叮我?)

网络上的大谣言(震惊!XX真的有害吗?XX是不是骗局?)

宇宙里的真奥秘(黑洞到底吃什么?时间旅行可能吗?)

前沿科技的酷炫原理(AI为什么能下棋?量子计算到底在算啥?)

通通“嚼碎”了,用最有趣、最接地气的方式,送到你耳边。

在这里,知识不再是高冷的名词,而是像扭蛋机里掉出来的惊喜小玩意儿,让你每听一期,都忍不住想“再嗑亿点点”!

订阅《知识“嗑”学家》,让好奇心驱动大脑,跟金卫一起,轻松解锁你不知道的科学真相!我们不是科学家,我们是知识... more

该音频分享了一种利用人工智能进行深度学习的精细化方法,强调了在提问前进行议题拆解和思考至关重要,因为这能为AI提供必要的上下文(context),避免生成平庸的答案。作者认为,AI的应用将成为像使用Office软件一样的基本技能,而目前的AI能力已经足以深刻改变人类社会。作者的具体学习流程包括:先深度拆解议题并撰写包含思考的提示词(prompt),然后利用GEMINI等模型进行深度研究(deep research)生成多份聚焦报告,接着将报告导入NotebookLM等工具中,通过问答完成AI辅助... more

该音频深入解读了一项由协和医院神经内科团队主导的、针对安宫牛黄丸疗效的高质量多中心双盲临床实验。文章揭示,尽管这种传统药物被广泛视为“神药”,但该实验以严格的科学标准来评估其对中重度脑梗患者减少梗死体积和脑水肿的效果。核心结论指出,安宫牛黄丸在临床上被证明是安全的,但在减少梗死或水肿体积方面没有统计学上的显著疗效,尤其强调判断疗效的关键在于P值是否低于0.05的及格线,而该药的大部分评估指标均未达标,只有在大动脉粥样硬化型(LAA)患者的亚组分析中显示出轻微的积极信号。资料旨在用数据和严谨的科学... more

该音频围绕一个听众关于固态电池必要性的提问展开,卓克通过分析电动汽车在不同驾驶条件下的实际续航表现来回应。文章指出,尽管现有电动车在城市中能达到较高的续航里程(如700公里),但在高速公路等对续航有硬性要求的场景下,为了确保安全冗余,现有电池技术仍无法满足长途驾驶者的需求。固态电池的成熟体能够将续航提升1.4倍,使得最严苛条件下也能达到640公里以上,从而跨越了“里程焦虑”的门槛,并且在安全性上远胜传统液态电解质电池。虽然固态电池在实验室中已成熟,但目前的主要挑战在于如何找到稳定可靠的批量生产方... more

该播客深入探讨了Sora 2带来的三个颠覆性创新——Remix二创功能、Cameo客串功能和社交化产品设计,认为这些进步将彻底重构内容创作和广告行业。Remix功能让用户能够轻松地对AI生成的视频进行二次创作,将每个视频变成可无限修改的模板,从而极大地降低了创作门槛。Cameo客串功能允许用户提供自己的影像和声音,将自己“召唤”到任何AI视频中,这不仅使人人都能成为“数字演员”,也预示着一个全新的**“数字肖像权”市场的诞生。最终,Sora 2作为一个名为“Sora”的新App被设计成一个AI版... more

该音频解读了 2025 年诺贝尔生理学或医学奖,该奖项授予了美国科学家玛丽·布伦诺(Mary E. Brunkow)、佛瑞德·拉姆斯德尔(Fred Ramsdell)和日本科学家坂口志文(Shimon Sakaguchi),以表彰他们对外周免疫耐受的研究。文章详细区分了中枢免疫耐受(发生在胸腺中的T细胞筛选训练)和外周免疫耐受(在身体外周发挥作用的“刹车”机制),并指出中枢训练并非万无一失,仍会输出可能攻击自身细胞的中等亲和度T细胞。坂口志文发现了这种“刹车”机制的关键执行者是调节性T细胞,而布... more

该音频是对 2025年诺贝尔物理学奖 的深入解读,此奖项授予了约翰·克拉克、米歇尔·德沃雷特和约翰·马丁尼斯,以表彰他们在电路中发现“宏观量子隧穿”和“宏观能量量子化”的杰出贡献。作者卓克指出,这项基础理论支持了量子计算中的一条关键技术路径——超导量子比特,因此该奖项被视为科学界对量子计算未来发展前景的一种预测与认可。文章随后详细解释了宏观量子隧穿效应(即一个由大量电子构成的宏观电路自发越过能量壁垒产生电压)和宏观能量量子化(即宏观电路像单个原子一样,对电磁波的吸收有离散的能量分级),并阐明了这... more

该音频是对 2025年诺贝尔化学奖 的详细解读,该奖项授予了日本的北川进、英国的理查德·罗布森和美国的奥马尔·M·亚吉,以表彰他们在 金属有机物框架 (MOF) 开发领域的开创性贡献。这种全新的化学结构内部遍布巨大的孔洞,能够实现对分子的 选择性进出,其发明可以追溯到罗布森在制作分子模型时产生的“上帝视角”设计理念。文章详细介绍了三位科学家的关键贡献:罗布森是该领域的创始者,北川进通过实验验证了MOF孔洞的柔性和可逆吸附能力,而亚吉则通过细致微调扩大了这种材料的应用范围,尤其是在芯片制造等高附加... more

该播客音频记录了 2025年诺贝尔生理学或医学奖 的宣布及其背景,该奖项共同授予了 Mary Bronco、Fred Ramstell 和 Shimon Sakaguchi,以表彰他们关于 周围免疫耐受 的发现。免疫系统必须在有效对抗微生物的同时,避免攻击自身组织,从而预防 自身免疫性疾病;三位获奖者的工作揭示了免疫系统如何通过 调节性 T 细胞(T-regs)来实现这种平衡。Sakaguchi 首先发现了这些具有保护作用的 T 细胞,而 Bronco 和 Ramstell 则确定了对 T-re... more
