When a musician says they are playing 2 steps down what does that mean? | [

Dictators and why people see to blindly believe in them? | [
"The simple answer is that by the time someone can be called a dictator, they've taken over the media, silence dissidents, censored the internet, murdered/jailed the opposition party and control information to the point that an alternative to the narrative doesn't really exist. Especially when so many people are ju... | [

"Rubber IS the best material for soles. Foam is winning because it makes money. They use foam because it's less expensive to manufacture. Foam in easier to form, the materials cost less, the result is more flexible and lighter weight. But fuck foam. Foam sucks. It may be cheaper but that savings wasn't passed on ... | [

How come superheated water doesn't appear to be boiling? | [
"Water molecules are terrible at figuring our what state they are supposed to be in. They need some external influence to show them what to do."
] | [
"> I would think any liquid in an airtight container such as a sealed can or bottle would cause more of an implosion than an explosion as the liquid contracts in the cooling. Water is weird compared to most molecules - it expands when it freezes, it doesn't contract."

Wouldn't all parasites be killed by our stomach acid? How do tapeworms and other parasites survive though the digestion process? | [
"The egg coating is thick enough to survive the stomach acid. But that breaks it down enough that they are able to hatch in the small intestine. Been watching the Monsters inside me on Netflix, be surprised what you can learn about these little critters."

"They can and sometimes do. But the lining of the intestines is very rich in lymphoid tissue. White blood cells can quickly access the area and contain the infection. Additionally, any infections arising from this area are likely to be not aggressive as we have lived with those bacteria our whole lives. In a manner... | eli5_question_answer | {

Why does some food/drinks taste best when served hot, others when served cold? | [
"Temperature is related to how our nervous system is able to process the signals for taste and smell. For instance sugar is much sweeter at high temperatures than low temperatures.
