How Viruses Are Discovered
嗨，我叫迈克尔，
我将在不到一分钟的时间内 描述病毒是如何被发现的。
你知道病毒是如何被发现的吗？
你可能会像我以前那样想。
找到一个病人， 采集他们的粘液样本，
然后从他们的粘液中分离出病毒。
如果你和我一样也是这么想的， 那你就百分之百错了。
病毒学家实际上是找到一个病人， 采集他们的粘液样本，
将粘液加入细胞培养物中， 再向细胞培养物中加入有毒化学物 质，
最后减少细胞培养物的养分， 让细胞挨饿。
做完这一切之后， 他们注意到细胞死亡了，
然后声称里面一定 有某种病毒。
接着，病毒学家提取一小部分 细胞培养物样本，
将其输入机器中 以获取基因片段，
将这些碎片输入软件， 然后尝试将它们拼接在一起，
从而生成新的病毒基因组。
你认为这位病毒学家的 发现过程是可靠的科学吗？
你确信病毒真的存在吗？

Original transcript (English)
Hi, my name is Michael, and I'm going to describe how viruses are discovered in one minute or less. Do you know how viruses are discovered? You might be thinking like I once did. Find a sick person, take a sample of their mucus,
and separate the virus from their mucus. If you thought this, just like me, you would be 100 wrong. Virologists actually find a sick person, take a sample of their mucus, add that mucus to a cell culture, add toxic chemicals to the cell culture, and finally reduce the food to the cell culture, starving the cells.
After doing all that, they notice the cells die, and then claim there must be a virus in there somewhere. Virologists then take a small sample of the cell culture, feed that into a machine to get pieces of genetics, feed those pieces into software, which then tries to fit things together,
creating a new viral genome. Do you think the virologist's discovery process is valid science? Are you convinced viruses exist?
