四、课堂讨论题
1. 老师,讲稿里说电视雪花里有1%是宇宙大爆炸的残留物造成的,这里的 'accounted for' 具体该怎么理解?是‘解释为’还是‘归因于’呀?
2. 我注意到 'tune' 既可以说调收音机频率,也可以说乐器音准,这两个用法在语境上有什么细微的区别吗?
3. 文中提到 'dancing static' 指的是静电干扰,那 'static' 在这里除了指‘静电’,还有没有其他引申义?它和普通的 noise 有啥不同?
4. 为什么 Dicke 团队能迅速发现彭齐亚斯和威尔森的咳嗽其实是受背景辐射干扰影响,而这两位天文学家自己却一直没意识到?这里面的原因分析是啥?
5. 讲稿最后说 'You can always watch the birth of the universe',这句话除了字面意思,在科学传播或者科普语境下,还有什么更深层的趣味或意义吗?
五、Discussion Questions (English)
1. Teacher, the transcript says 1% of the TV static is caused by the remnants of the Big Bang. How exactly should I understand 'accounted for' here? Does it mean 'explained as' or 'attributed to'?
2. I noticed that 'tune' can refer to both adjusting a radio frequency and tuning a musical instrument. Is there a subtle difference in context between these two usages?
3. The text mentions 'dancing static' referring to electrical interference. Besides 'static electricity', does 'static' have any other extended meanings here? How is it different from regular 'noise'?
4. Why was Dicke's team able to quickly identify that Penzias and Wilson's coughing was actually affected by background radiation, while the two astronomers themselves didn't realize it? What's the reason behind this?
5. The transcript ends with 'You can always watch the birth of the universe.' Besides the literal meaning, does this sentence have any deeper significance or appeal in the context of science communication?
