Why do modern fighter aircraft have their wings mounted higher than in the past? | A simple answer is that most fighter aircraft today have a "[blended wing]" design. This means that there is less surface area on the plane that comes in contact with airflow, and reduces interference between airflow over the wing root and the adjacent aircraft body. Again, this is just one of many design reasons for t... |

Why do speedometers always exceed a car's top speed? | It is aesthetics--car manufacturers want to have the speedometer needle pointing straight up when you're at highway speeds to make it easy to see.

Will a bullet fired in space have a curved trajectory because of its spin? | **Edit**: It appears that I am **incorrect**, and that in the absence of gravity or atmosphere acting on the object in OP's theoretical gravitationless space, **it would not change direction**. I apologize for the incorrect response; it was given in good faith. My original response, is below. **See the follow-on commen... |
Why is SpaceX attempting to land on a barge rather than land? | It's all about the trajectory. The Blue Origin rocket went straight up and down, so it could land on it's own launch pad. All it did, trajectory-wise is go up and down. SpaceX rockets go to orbit, which involves an awful lot of sideways, so when it comes back down, it's nowhere near it's launch pad. So the barge is dri... |
why you would buy spf30 sunscreen when spf50 is the same price and same time of protection? | SPF30 is likely to be less thick than SPF50. That is one selling point to a lower SPF. SPF30 is usually cheaper than SPF50, however, this is not always the case. Furthermore, more expensive brands are not always more effective than cheaper brands.

Why does sled retain speed if a person falls of from it sideways? | The momentum of the sled doesn't stay the same. The total momentum of the system is conserved. So Susan's momentum + empty sled's momentum= the original momentum. The important thing here is that horizontal and vertical speed are independent of each other. As long as Susan leaves perfectly sideways, the original speed ... |
What are the chances the U.S. dollar will devalue and the U.S. will enter into another Great Depression. Why and why not. | The chances are near 100%. The question is not *if* the question is *when*. The reasons is because this is the nature of economies. They have slow growth, big booms, and times of declining size. Will the US have another great depression, yes.

Why do you want to get 'Married' | My wife and I have been together for 16 years; we got married two years ago.

As our bodies (eyes) grow, does our field of view increase? Or do our eyes remain the same size throughout our lives? | No. You have the same field of view. It differs with the person. The Army Air Corps tested for field of view in potential pilots. The air force still may do it. The eyes grow a bit.

For televised football games, how do the lines and graphics on the field work? | The answer is a huge amount of computing power. A 3D model of the field must be programmed into the computer first, indicating where each yard is, as well as where all the bumps and slopes on the field are. The cameras are mounted on special rigs that monitor every movement the cameraman makes. The computers are progra... |
filibustering. What is it, how is it used, and why? | A filibuster is a parliamentary tactic used to stall legislation. The traditional filibuster arose from the fact that Senate rules had no limit for how long a debate could go on. Whereas the House has limits on that, so you can only debate a given bill for so many hours, the Senate does not. People realized that you co... |
Why does imagining running water increase my urge to pee? | I would imagine it's a conditioning response, very similar to Pavlov's infamous dog experiment. From the time we first start learning to use a toilet, we associate the sound of water noises with urination. We pee, it makes a certain noise. You hear that over and over again for years, the two become linked in our brains... |
How does Hyrdofoil work? | A hydrofoil is a wing shape that produces lift through it's path through the water.

I can rarely understand the words in modern music. Do I have a mental issue, or is it like this for everyone? | So many musicians don't know how to enunciate. It's annoying. Too many people think their mumbling is good music. Now, I loved Nirvana's sound, but Cobain couldn't get three words out with enough fluency for my ears. Weird Al is someone I love to listen to because I miss fewer words. He knows his music is ridiculous, s... |

I've seen Mr. Smith Goes to Washington. But can someone explain a modern-day filibuster? Like I'm five? | There are 100 votes in the Senate. It only takes 50 of them to pass a law, but it takes 60 of them to decide that they have learned enough to pass a law.

What is the evolutionary purpose of having two nostrils? Why isn't it just one hole? | That's a bad way of looking at it. Evolution doesn't go around fixing what's "wrong". It just tends to eliminate the stuff that decreases the chance for survival. Nothing about having 2 nostrils is having an adverse effect on those animals that have them. There's even a benefit. Most people have experienced having just... |

Probably from tinted moisturizers, as most men who use them are told not to use it around their eyes, leaving them with a reverse-raccoon look.Add in the blindingly white teeth and you've got yourself Rich Man's Oompa Loompa syndrome. Donald Trump does it pretty poorly as well. |
Why are mobile bandwidth caps much lower then Fixed line bandwidth caps ? | There are two issues.

Why does the United States keep interfering with other countries in conflict ? | Others will probably say something about humanitarian efforts or that we have alliances to protect, but as my high school history teacher always said, "It's about money."

Why are weigh-ins always several days prior to a fight, allowing fighters to potentially enter the ring at a completely different weight, rather than right before the fight? | Basically it gives fighters time to adjust their weights, not take the fight, work out new terms of the fight, etc. If you held it prior to the fight, and someone didn't make weight, you would have a stadium full of people and a maybe fight.

What's going on in China right now? | Through some general imperial shadiness, the British took Hong Kong from the Chinese. To give it some authenticity, they signed an unimaginably long 99 year lease with the Chinese government. A few years back, that lease expired and the British gave Hong Kong back to the Chinese. Because Hong Kong had spent a century u... |
The cable companies arguement to "Data Cap" my monthly internet usage is to prevent congestion of the system during peak hours. Can it really be congested? | Yes, it's true.

Why do the fork, knife and spoon seem universal? Where did they originate from? | The book [The Evolution of Useful Things] is a brilliant book that covers this topic and many others.

EDIT in a little more explanation: It was quite co... |
Why aren't there hyper-realism paintings from decades/centuries ago? | Smaller talent pool. Nowadays there are billions of people who can have access to quality art supplies, and share their work worldwide easily. Many centuries ago the number of people who had the ability to spend free time painting was much smaller, so the top 1% of them weren't as good as the top 1% today. Also, you're... |
Why do we look down on HGH users when it is perfectly acceptable for women to use hormone replacement therapy. | I think HGH is looked down on because it is linked to cheating in athletics and sports.

How Wendy's is able to not give management breaks, legally. | Federal labor laws don't require any company to provide breaks for their employees.

Whenever it got a little busy, breaks and lunches were cancelle... |
How do I tell it a survey-based sweepstakes is bullcrap? | Read the fine print. Sometimes, it's the real deal. But most of the time, there's a reason behind it.

Additionally, the battery chemistry matters, so your normal alkaline battery will have more resistance t... |
The ultimate microwave question. Why does it take 3 minutes to cook my hot pocket/lean pocket in the microwave but 30 minutes to cook in my oven? | It's not a comparable means of cooking. Microwaves agitate the molecules in the food and produce heat through this agitation.
