I admit that on its face it sounds ridiculous for a court to order parents to p... |

Growing up my mother always told me to never start a pot of boiling water from hot tap water only cold. What's the logic behind that if any? | I'll attempt to sum up all the reasons: 1. Lead and other contaminants dissolve much more easily in hot water. This can lead to unwanted tastes, and could possibly build up to harmful amounts of chemicals in the bloodstream if consumed routinely. 2. The hot water tank isn't necessarily a clean place. A sludge made of m... |
Why are talking animals so ubiquitous in children's media? | Honestly, I think it's to bypass uncomfortable stereotypes. Imagine if the Big Bad Wolf were a specific race or class and how that would play out it in today's world. |
How come I can remember things from years ago but can't remember if I locked the door 5 minutes ago? | Part of the reason is muscle memory. When you've done something so many times you can literally do it without thinking. Your brain can compartmentalize what it deems unessential or easy enough to do without your concentration. It happens all the time. It's the same mechanisms as when you're driving somewhere you've dri... |

If space shuttles have a specific orbital speed & trajectory, how were astronauts able to maintain the same speed/trajectory as the shuttle while performing untethered spacewalks? | > how were astronauts able to maintain the same speed/trajectory as the shuttle while performing untethered spacewalks? Because once you're moving at a specific speed, you will keep moving that speed forever unless some force slows you down . When the astronauts exist the space shuttle, they're still moving at the same... |
Could someone explain Buddhism to me LI5? | By the way, atheism doesn't preclude Buddhism. Buddha didn't care for figuring out if there were any gods that existed, he just focused on living the good life and escaping from suffering. So really, you can be an atheist and be Buddhist.

How does running help you live longer if it wears your heart down? | the point is that overall fitness will increase your lifespan because obesity is bad for your health. there's really no research that shows the heart is suspected to wear and tear, unless you're really raising the heart rate to extremes. |
when we first started measuring temperature how did we decide how large a degree would be? Was it merely and arbitrary figure that worked, or was there a specific reason behind it? | I assume you mean the Farenheit scale. Fahrenheit's scale was based on the work of Ole Rømer. In Rømer's scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees. Fahrenheit multiplied each value by four in order to eliminate fractions and increase th... |
The structure of middle eastern music | could you be more specific on what you want to know? I might be able to give an answer, but it really depends on specific countries and if you're talking about how the music is composed, put in order, performed. |
