Why hasn't Leonardo Dicaprio won an Oscar? | He's pretty much always been nominated in tough, competitive years. 2013 was stacked with great performances and it's hard to argue against Forest Whitaker for 2006.

why do some find human euthanasia so objectionable while they seem to have no problem with it for their pets? | There is some sense that animal well-being is entirely physical, while human well-being is existential.

I understand trying to prevent suicide, but ... |

Why Puerto Rico is still an unincorporated territory of the United States? | The simple answer is because their government has not requested a change in their status.

What defines a different species ? | This is actually a very [hard question] because the real answer is that nature doesn't provide a hard, definitive line.

why do some people's joints "crack" easier than others? | I can tell you from personal experience that when my joints crack a lot it's when I'm out of shape and spend too much time sitting down. I rarely exercise and I usually sit for 8 hours+ a day, so when I stand up my joints always crack! This wasn't the case when I was more active. When I stand up and stretch it sounds l... |

But everything else was a normal size because they pri... |

The numbers specify coordinates in the sky relative to Earth's equator: the right ascension is 18h 28m and the declination is 26° 50'. It's more in... |
Why we have megabits and megabytes and why they haven't/can't be consolidated | Because different things are important in different places. Networks don't care about bytes. You could invent a completely new type of computer that had 10 bits to a byte, and your network would be fine with it. All the network cares about is how many ones and zeros go by, so it is much more meaningful to talk about me... |
How does scent travel? Look inside | The short answer is that there is always airflow. It's just on the microscopic rather than macroscopic scale.

Why do whales surface to exhale, and when do they inhale? | Exhaling under water decreases buoyancy. Try it next time you're at a pool - humans generally float with full lungs but sink after fully exhaling. Exhaling *before* surfacing makes it more difficult to surface. |
If I attempt something with 1% probability 100 times, I don't get a 100% proability. What probability DO I get and how do I calculate that? | This kind of thing is called a [Bernoulli Process], which is complicated and hard to ELI5. But in this specific case, if you're asking “what's the probability that I win *at least once* in 100 attempts” the easiest way to answer it is to reverse the question: “what's the probability that you don't win at all in 100 att... |
What is going on in the UK regarding their internet and even uses of Snapchat/Imessage/whatsapp | The government is planning new laws which the media are calling the "snooper's charter". The basic gist of it is that they want the ability to decrypt any message sent over the Internet. To do this they want every company that provides encrypted services to build in a "back door" which allows them to access users\' mes... |
How does the show “planet earth” get their shots without scaring the animals | The telescoping lenses they use are INSANE basically, a large part of it is zooming in really really really close from really really really far away. other parts of it is remote infrared sensing cameras that record when something near it moves . finally they can use drones to get some shots, possibly combined with the ... |
How could an additional source of light make the light from my phone or TV easier on my eyes? | If the room is overwhelmingly dark, except for the TV, then your pupils will be wide open to let lots of light in. If the room is relatively bright, your pupils will be smaller and thus let less light in. The idea is that this lets less "harmful" TV light in, although TVs themselves shouldn't give off too much harmful ... |
Why does a microwave take more time to cook multiple things (thing pizza rolls or something), but an oven does not? | An oven works by heating the air within to a certain temperature say 350 F, doesnt really matter. 1 pizza roll surrounded by 350 F air will cook in 3 minutes. If i put 2 pizza rolls in the oven, both are surrounded by 350 F air and will still cook in 3 minutes. regardless of how many pizza rolls are in the oven the air... |
how come lobsters became so expensive? They used to be poor man's food. | Say there are 100 school kids and they all enjoy cheap cheap jello. When 4 of the kids decide they want all the jello - It's tasty - It's sexy - It makes them feel rich - religious reasons. Supply and demand kicks in. They buy up all the jello and that drives up the price. Fun fact : Shark fin soup has very little tast... |
What makes the Venezuelan national debt of 60 billion so much worse than the US national debt of 20 trillion? | The inability of the Venezuelan government to pay interest on that debt, and keep their own government functional. In the same way that $1M in debt by Microsoft wouldn't really impact anything, but $1M in debt by me would be crippling. |
Why did people build cities along earthquake fault lines? | Most of the fault lines are near or run along the coastlines. People liked building cities on the coastlines because of the water access was necessary for transport and travel. All of New Zealand pretty much sits on a fault line so they're hooped regardless. But people didn't know this two, three hundred years ago when... |
