why does it look like big (really big) things fall slower than smaller things? | They appear to move slower relative to themselves. Consider a ball 1 cm across, and one 10 meters across. In the first second of falling, each will fall the same distance; about 5 meters. But the first ball will have gone 500 times it's diameter, while the second will have traversed barely one of it's radii, appearing ... |
If all polar caps melted, would we be able to consume seawater due to the reduced salinity? | nope, because even a few meters increase in Sea level is far less than a 1% increase in total ocean volume. The ocean is really really big. So we would still be fucked without the added benefit of extra drinking water. If anything it might reach some near coast lakes and ruin those. |
Some people tell me I'm legally required to pay income taxes, and some tell me it's unconstitutional.

How is it possible to self-plagiarize yourself? | The concept is poorly named by people with a limited vocabulary. Your instinct that the sin of plagiarism lies primarily in taking other people's work is right--that is the origin of the term.

How can the Sun's gravitational pull be strong enough to keep Pluto in orbit but not just pull Mercury into it? | The Sun's gravity is pulling Mercury, but the planet is traveling so fast that it can't fall fast enough to ever hit the Sun. Mercury's orbit is elliptical though, so it does vary in distance from the Sun. As it gets closer to the Sun the pull from the Sun's gravity does increase, but so does the orbital velocity of Me... |
How can or why would someone consider themselves being transgender without being pre-op or post-op? | I'm no expert - but surely it's possible for someone who was born a man to feel like a woman, to chose to live her life as a woman, dress like a woman, and identify as a woman, but not want to undergo major surgery? And vice versa. All surgery is risky. I would imagine that your friend would have their genitals changed... |

What happens to an embassy when the country it represents gets declared war on | International law would dictate they are given safe passage back to their home countries, but in practical terms, whatever the country they are in wants.

Why does combining a gyroscope and an accelerometer only give me the pitch - roll orientation and not yaw? | You can measure yaw just fine. The issue is that based purely on accelerations, you can't have a stable yaw reference over time. What's being measured is only the _rate_ of rotation, not the orientation itself. Any errors or noise in the sensor data or the integration process will add up over time to wreck your referen... |

Why do movies look smooth at 24 fps but video games look choppy under 60 fps? | A computer frame is a rendering of an exact point in time.

My Windows 95 computer from '96 can run Doom and stream music in the background, but my Windows 10 2016 Xbox can't. Why? | It can, technically speaking hardware wise. The thing is that its Operating System is not coded/configured to do it, as a choice from the developers.
