While sitting in a moving bus, if we throw a ball upwards, why does it still come back to our hands instead of falling behind?
Basically, your question centers on the idea of a reference frame. When you are sitting on the bus, you feel like you are not moving, right? But, actually, you are. You're just not accelerating. In fact, at no time in your life have you ever been sitting still--the whole time, you've been moving at the same rate as the earth as it spins around its axis and revolves around the sun.The reason you don't notice this motion is because everything around you is also moving with the earth. The earth is your reference frame--that is, the only motion you actually notice is something moving differently from something else, like watching a car driving down the road. The road is “still” in your reference frame, so the car is “moving.”The same idea applies on the bus. If the bus is moving at a constant velocity (a constant speed in the same direction), everything on the bus seems to be unmoving, including you and the ball in your hand. That's because you and the ball and the seat you're sitting on all have the same velocity as the bus. When you throw the ball up in the air, you don't change how fast it moves forward, so it continues at the same speed as the bus and drops back into your hand.If the bus were to accelerate in any x-direction (if it increased or decreased it's speed or turned right or left) while the ball was still in the air, the ball would “move” in the opposite direction, because, not being in effective contact with the bus (the air is a non-viscous fluid, so the ball can move through it without being greatly effected), it would continue with the x-velocity it had when you first threw it, because “an object in motion tends to stay in motion unless acted on by an outside force.” And that's the basic reason. Newton's First Law.
As a married couple, do you sometimes sleep in separate rooms just so you can both get better sleep?
I am so happy I found this question!Yes, my husband and I sleep in separate rooms.In the beginning of our marriage we slept together every night. We would cuddle, hold hands, make love and sleep. But after the honeymoon phase was over, I realized a few things.1) My husband snores and it has gotten worse with age. On the other hand, I’m a very light-sleeper. I can actually hear my cat walk across the carpet and jump onto the bed. So there would be nights when I only got a few hours of sleep because of his snoring and I’d still have to work in the morning.2) My husband likes to be cool and I like to be warm. He would throw the comforter off the bed at night because he was too hot and I would get cold and wake up. Then I started putting the quilt on my side of the bed, but he hated that because it was too heavy. So there was always a struggle over cool/warm at night.3) He tosses and turns all night and because I’m a light sleeper, he would wake me up. So again, I only get a few hours of sleep before my alarm went off.4) He likes to get up early and I like to sleep in (weekends only) so he jostles the bed and uses the in-suite bathroom, which wakes me up.5) It takes me 30–60 minutes to fall asleep and my husband is asleep as soon as his heads hits the pillow. And because of his snoring, it takes me even longer to fall asleep.6) SEX; I enjoy having sex, but not as often as he does. I enjoy sex about once a week and he wants sex every night. Sometimes I just want to sleep. He also likes sex first thing in the morning, which I HATE. If I was sound asleep and he woke me up for sex, I considered that to be unbelievably selfish.So after my daughter moved out of the house, I immediately turned her room into a guest bedroom and I sleep in there almost every night. My husband sleeps just fine without me and I get a FULL nights sleep, before going to work. I visit his room once a week for love-making and everyone is happy.
What is the worst car crash you've ever seen or experienced?
20 years ago - 1996 I think it was - I was driving back home with my then gf from Auckland (I lived 160km away). It was raining and I was speeding because I wanted to get home in time to watch the X-Files. I was an idiot.I came zooming round a corner at 120kmh and found a bus stopped in the middle of the road. I found it very interesting just how time really does slow down in these high-adrenaline situations. In the second or so before I hit the bus, I saw a car coming the other way on the other side of the road and immediately weighed up that overtaking the bus was a bad idea as that would mean a head-on with the oncoming car, which means greater combined force. On the side of the road was a deep ditch and again I realised going that way would be certain death. My only option for survival was hitting the bus. As I made my decision, I turned to my gf and said, “I'm really very sorry about this.”All this in about a second!We hit the bus but unfortunately the bus was high up and instead of smacking into the back of the bus, we went under it!The force of the collision tore the side struts off the car windscreen and crumpled the roof. By sheer dumb luck my car hit the bus's back tires, and this stopped our progress. The back of the bus ended less than an inch from my face. Another foot or so…I ended up with a tiny scratch on my thumb. My gf was less lucky being seated further forward. The top edge around the windscreen hit her head so she was bleeding rather profusely but fortunately not seriously (headwounds are messy). Later when she was taken to hospital we found she also had whiplash.The fire dept were already there due to road flooding (which was why the bus was stopped). One of the firemen cheerfully offered me my car's radiator cap - he found it 2 cars in front of the bus. This should give you some idea of the force of the collision.Had I driven for the road conditions - say at 90kmh - we would have missed the first 5 or 10 minutes of that evenings X-Files episode. As a result of rushing we missed the entire episode, destroyed the car and ended up spending half the night at the hospital. Oh, and I got a traffic infringement ticket.There's probably a moral in there somewhere…

X-files episode written by Stephen King?
Does anyone know the season or name of the episode of the X-Files that Stephen King wrote? I remember the storyline was with 3 deformed brothers and they tried to reproduce with their mother.
