it was just a splinter of wood,
đó chỉ là một mẩu gỗ nhỏ,
people had found

No, we got this.

It's kind of important.

That's amazing -- if it's true.

Why you should listen
The history of science is "brimming with tales stranger than fiction," says Latif Nasser, who wrote his PhD dissertation on the Tanganyika Laughter Epidemic of 1962. A writer and researcher, Nasser is now the research director at Radiolab, a job that allows him to dive into archives, talk to interesting people and tell stories as a way to think about science and society.
