How can the same dose of a drug be OTC and RX at the same time?
Bureaucracy and regulatory capture. Generic preparations of OTC drugs still have to pass FDA scrutiny.

What is the symbolic fear represented by dead young girls in the movies (e.g. The Ring)
Because children are innocent, loved and protected while adults can be monsters.

why does time seem to move quicker when I'm occupied?
The prevailing theory is that, when a brain is occupied with a task, then it has to spread its resources, leaving little to spend focused on the passing of time. However, if nothing in particular is occupying our conscious brain, it takes more notice of the time ticking by. The funny thing is, this slower vision is tho...
How a company can trademark a single word and prevent the word being used in anything?
You're a little confused about how trademark works. Trademarks protect the look and branding of a specific product or class of products. The protection they grant is limited in scope.

What would happen if we were more transparent with our national security plans?
If we say, "Russia can have the Ukraine and one of the little Baltic countries before we're mad enough to send over an army" that's an invitation to an adversary to commit mischief.

Why don't animals pull their muscles when exerting themselves?
IamA veterinarian. Animals over exert themselves all the time. My favorite example is the guy who came to see me for lameness in his 10yr old dog.

Why does an e-reader screen flicker so badly on each refresh?
There are two reasons for this. The pixels of an e-reader is based on the physical movement of the pigments to the back or the front of the screen.

Does your stomach stop telling you that you are hungry based on the weight of food you have eaten, the volume of it or something else?
The cue to stop eating is a combination of several factors. 1) Blood sugar reaching a certain level. Your blood sugar starts going up fairly quickly when you start to eat. Once you get to some minimal levels that is one signal that you have eaten enough. 2) Volume. Your stomach knows how full it is and it will signal t...
Why do we need surround sound, when we only have 2 ears? Alternatively: how do I know a sound is coming from the front or back from me?
You seem to understand that the ears can localize sounds based on the slight delay it takes to get to the near ear and the far ear. In cases where there is no delay - something in front or behind you - there are other mechanisms. The shape of your ear filters out different frequencies of sound differently, and it also ...

Why do people invest in gold and silver?
Personally, I do it to diversify. Gold and silver have held value throughout time, but who knows what will happen to various markets? & nbsp;I know that in the past, people flocked to it to hedge against inflation.

How do smartphones that run multi-core cpus stay cool with such a compact design and zero airflow?
Most smartphone CPUs are ARM based, which are designed to run cool and use a small amount of energy. Per Mhz, those ARM cpus will provide less computational than an x86 CPU of the same speed.

How are EULAs legal in the United States if you can't return the software after you've "purchased" it?

I'm not sure that it's true the people *always* give away their lies with some sort of bodily signal, but you're right that there are often signs. There are a few reasons for this. One is simply that lying is cognitively more difficult than telling the truth. Think about it this way, which is easier: reading from a scr...

How come the third rail on subway systems doesn't short circuit when it gets wet?
1. Water on the rail itself doesn't short circuit, as the rail is more conductive than the water. 2. The water doesn't bridge between the third rail and a suitable ground. It might drip off, but it won't form a continuous path like a wire very easily. 3. Water is an awful conductor, so outside of very high voltages suc...

Why is the sound of someone snoring so annoying when we're trying to sleep?
I imagine it's at least partly because the sound is irregular. Traffic, air conditioners, and rain are very rhythmic. Predictable sensory input is input that our brain ignores, which is why you only smell things for a short period of time. Snoring is jerky and hard to predict so you never adjust. I could also be wrong.

If someone stuck you with a needle and injected nothing, it would liter...

Why cant we just make up a number when we divide by 0 by 0
You could define it to be anything you want, but such a definition isn't very useful. Suppose that you decided to define multiplication in such a way that zero has an inverse. Then for any number x you would have: x=x *1 =x * = *0 =0 Therefore, if you allow zero to have an inverse, then either the only number in your s...
what is that noise we hear when we put our ear in an empty shell?
Cupped shapes focus noises. Think of the megaphone shape on an old phonograph, your ear, an owls face, or just turn a song on your phone, make a cup with your hand, put it between the speaker and your face and you'll hear the volume go up. That shell is esentially that same shape. Background noises, like wind, air cond...

When you don't have to worry about rotating your tires, you can tailor the kinds of tires for the application to inc...
Why can't "superbacteria" live outside hospitals
It's not that they can't live outside of hospitals, it's just that hospitals are great places to go if you want to catch antibiotic resistant bugs.
