ulvyp | To Viking experts: What was the music like? | I came into a discussion with a friend about Viking metal and we talked about what actually gives us a feeling about Vikings when we listen to it because many of the instruments and sounds used in this genre are very modern. In my brief research in original Viking music, I stumbled upon "Drømde mig en drøm i nat" and ... | AskHistorians | http://www.reddit.com/r/AskHistorians/comments/ulvyp/to_viking_experts_what_was_the_music_like/ | {

fq1kyp | How does soap remove compounds besides lipids? | With everyone being told to wash your hands, I wanted to understand more about the mechanism by which soap works. I understand with lipids (fats, oil, COVID-19) the lipophilic characteristic of soap will bind with lipid layers. Once bound, they are then removed when rinsed away or torn apart via mechanical action.

14o2kl | Is it unrealistic to assume all intelligent life would be humanoid? | You see in almost all scifi that intelligent life is bipedal with arms with dexterous hands, a head, etc. It seems like life could be in all shapes and sized, but so far, the things that make us humanoid are also what makes us intelligent life.
