How come when you make a “hooo” sound out of your mouth, the airs cold. But when you make a “haaa” sound, it’s hot air? | The velocity of the air. When you go "haaa" your mouth is wider and when you go "hooo" it's narrower, so if your lungs are compressing air at the same rate for each mouth shape the speed of the breath will be slower on your "haaa". Why does speed matter? Your breath is the same temperature regardless of speed . Well by... |
Where is all the crypto currency data stored? | For many of the popular crypto currencies, not every client is running a full "node" with a full copy of the blockchain. Many "light clients" exist, which largely operate by communicating with nodes that do have a full copy of the blockchain. , A transaction is typically a short message signed with the owner's private ... |
Why aren't we all putting our savings in tax shelters? | Beyond the obvious "What savings?" issue, most people don't make enough money that the tax rates on interest are that big of an issue.

Animals getting saved from extinction. | I believe the smallest population size to prevent inbreeding is ~4000 individuals. If the species is limited to < 1000 individuals then inbreeding will be a serious problem which might cause the species to die out completely. There are methods to slow inbreeding such as planned mating with less-related members, cross-b... |

This receptor is expressed on sensory neurons which transmit temperature. Upon menthol bindn... |
Why does smartphone screenes show micro abrasions when most metals cannot scratch it? | Although metals are tough, they are not quite as hard as you think. You can get a tough metal by quench hardening carbon steel, but even those are scratched by things like sand and rocks.
