Can a city or county legalize weed? | The city/county could legalize it for purposes of city/county laws, sure. That said, even local cops have a mandate to enforce state and federal laws as well.

The whole area would continue to have this kind... |

And why can some sections of track not have them | They hold the rails at a fixed distance - without them, the trains would push them apart.

Pumping 1500 times more volume against pre... |
Can someone explain if Native Americans would ever have advanced to modern technology like Europe, if they were left alone? Like I'm 5. | This question falls under the bias that technological advancement is somehow better or more superior than any other form of life.

The newer ... |
Why do they call them "radiators" when really they heat by convection? | Maybe, since in the end the whole thing is radiating heat??In practice, the term "radiator" refers to any of a number of devices in which a liquid circulates through exposed pipes .

Why do young children pick their nose and eat it | Not an expert, just my opinion, I think as infants our hands are like our tongues.

Why do phallic objects startle cats so easily? | Sorry to repost this from last week but this has been done before I've noticed with a couple of ours that long thin cylindrical objects spook them more than other shapes.

The humor in some Adult Swim programs. | Heh. Well, first off, Adult Swim shows tend to have a streak of surrealism in them. They're weird and out there because they are supposed to be.

Why can't Obama simply executive order all the things he wants to do? | A lot of it he *can* do. The problem is funding.

Why aren't spacecrafts constantly missing their marks when planets like Mars are basically infinitesimally small, moving targets that are speeding through outer space? | Because the orbits of planets are observed for a long period of time, their future position is really well predictable. With a lot of math, a high precision at launch of the spacecraft and well planed mid-flight corrections via swing by at other planets, the spacecraft could meet with planet, where it was predicted. So... |
Whah happens when something dries? Where does the water go? | It'll evaporate at a rate inverse to the humidity.

What happens if an astronaut were to fly away from a station | I think it's important to point out that it would be pretty difficult for an astronaut to end up "flying away" from a space station at any more than walking speed.

Why is Australia so desolate when it is the same relative longitude as African and South American rain forests? | It's really Papua New Guinea that's around the same longitude as the rain forests - that's why it has so many rain forests.

How does a flash bang work? Does it actually blind a person, or cause impaired hearing, or both? | it's very bright. it temporarily blinds the eyes. there's nothing much you can do about that. it's basically like if you shine a really bright LED flashlight into your eyes or look into the sun for a bit it's very loud. 170-180db loud. a pistol gunshot is about 140-150. the decibel rating system is logarithmic so 170-1... |
How come we use the word "they" when talking about a single person? | English does not have a way to refer to one person who is either male or female.

In the USA there were more mass shootings than days in 2015 where 4 or more people were shot. What constitutes what gets reported on and makes global/national news and not? | Most of those shootings are gang/drug related.

If all of my cells have the same DNA, how do cells become specialized? | The process of stem cells turning into particular cells is called differentiation. This causes different genes to be expressed in the cell which changes it from a stem cell, to, say, a skin cell. It's possible to activate certain proteins, and researchers have done this, to then turn a skin cell into a brain cell. [Pre... |
What is Software Oriented Architecture (SOA)? | SOA is Service Oriented Architecture.

Colin Kaepernick and now Megan Rapinoe protest the National Anthem for racial murder from police or in general? | Neither. They're protesting inequality for minorities in general .

There isn't one unifying body that decides how things should be hap... |
Could you please explain how evaporative cooling actually works? | Water needs a decent amount of energy to actually change phases. This is called the enthalpy of vaporization .

Why do Curiosity and other 'space cameras' take photos in individual RGB layers? | Cameras you're used to using are designed to be able to capture a full image quickly.

How did ancient civilizations and people like the Athenians establish trade routes to places as far as Britain? | A little bit at a time.

Eventually, some enterprising Greek got themselves a boat and skipp... |
Why can't I taste the inside of my mouth? | Neural adaption. Basically, your brain only cares about a *change* in stimuli rather than every stimulus that comes along.

The movements are repeating over the course of a measure, so for 4/4 time the conductor will repeat a motion of 4 beats. The conductor further adds in the... |
Why we haven't returned to the Moon | Its really really really **really** expensive to go to the moon and there is not really much reason to go back. The US has also slashed NASA's budget to spend the money elsewhere, so NASA really could not afford to start another moon trip project.
