Why do countries with nuclear weapons have significantly more nukes than there are cities that they'd ever even consider nuking? | [
"Because once a nuclear war starts your first move is to go for the other guys nukes. So, if you have three times as many as you need, then you can afford to have 2/3rds of your subs, silos, and bombers destroyed. In the same respect, nuclear missile defense also lowered the effectiveness of nuclear weapons, causin... | [
"The simple answer is that the major super powers that would be involved in a world war all have nuclear capability and it would mean the end of the world as we know it. There wont be any agreement that we will go to war without using nukes."

How do Japanese and Chinese people use all of their languages' characters on a keyboard? | [
"What amounts to autocorrect. I don't have experience with Chinese, but for Japanese, you type sounds; and the computer \"corrects\" a consonant and vowel sound into hiragana; and then when you finish a word \"corrects\" hiragana into the appropriate kanji. I assume Chinese works similarly."
] | [
"It's not really the language itself that's simplified: when spoken, there's absolutely no difference. It's the character system, which has been simplified to make it easier to write and read."

Why does the world never react to terrorist attacks in 3rd world countries, like they do to attacks in wealthy countries? | [
"Same reason as why you referred to the West as \"the World\": you identify more with those you regard as close to you. Closeness can be geographical, political, cultural... I doubt many in Sri Lanka care too much about this Paris thing, for instance. Just like most Westerners didn't care about the Tamil tigers."

Why didn't a snake get poisoned by its own venom? | [
"Venom and poison are different. Venom is not 'poisonous' so you can eat it and it is fine. It has to be injected into the blood stream to harm you."
] | [
"Poison is either absorbed through the skin or swallowed; venom is injected, like a snake would. As the old saying goes: if you bite it and you die, it's poisonous; if it bites you and you die, it's venomous."

How is a diesel engine such as the VW TDI able to obtain better fuel economy than an unleaded engine? | [
"One of the factors which affects the efficiency of an internal combustion engine is the degree to which the working fluid (the hot gases) are allowed to expand, which is related to the compression ratio. Diesels use a much higher compression ratio, so they start off with a higher maximum efficiency. Add to that di... | [
"Diesel is also known as fuel oil. It’s more of a light oil than gasoline. Diesel engines rely on compression rather than ignition to burn. They don’t have spark plugs like regular gasoline engines. In larger engines diesel is better because you can get better mpg than gasoline engines. The larger engines have mor... | eli5_question_answer | {

Do you get electrocuted if you touch overhead electrical wires? Why? | [
"> Wouldn't the wires be coated in rubber or something similar? They are not coated. To do so would be prohibitively expensive and would make them much heavier, requiring more structure to support them. Touching power lines absolutely can electrocute you, which I was under the impression was ubiquitously known."

Why do some Li-Ion batteries in storage hold their charge for years, while others die after a few months and become permanently unusable? | [
"Lithium ion isn't one type of battery. It's a whole family of batteries that use lithium based electrolyte.
