It depends. Evolution by natural selection is a proven fact, but people have trouble with it on a larger scale.
Hell I'm as secular as they come and I have trouble with evolution on a larger scale. o_O

Trying to explain to an idiot I work with that a plane on a conveyor belt will indeed take off.
Please explain how. Unless the conveyor belt expells as much air as the plane would get underaround its wings if in motion I can't explain to myself how that can happend.

I just watched the mythbusters experiment and plane traveled some distance on the ground. I don't understand why they took it as a succesulf experiment.

A teacher tried to explain that three doors thing to me once, and I felt so slow for not getting it that I almost enlisted in the armed forces... (JK JK OH GOD JK)

Recently a friend of mine quoted "Glitter is the herpes of craft supplies, it never comes off!" and I said "haha Demetri Martin, nice reference (friend's name)" and she says "No that's off of 'some stupid show teenage women watch'." I then preceded to tell her "My bad, but they did take that from Demetri Martin.", and so we've been bickering about it for a couple of days...

Couldn't find a video to post to shut her up... Screw you Youtube!

I had to explain several times that while it has an equal and opposite force, Force equals Mass times acceleration, the bullet had a tiny mass and a lot of acceleration, the gun had less acceleration due to it's heavier mass.
Wouldn't that make the head (heavier mass) less accelerated?

This may be stupid compared to all of your science arguments but, I was playing pontoons(blackjack) with a group of friends, I had pontoons(ace+queen/jack/king/10) and my friend had a 5 card trick. So the rules are Pontoons>5card trick but they over ruled me and said his 5card trick beat my Pontoons, it took me 2sites stating the rules and me stating why would it be called Pontoons if something beats it.

One of my friends was stubborn and refused to believe my evidence.

Wow, people actually understood me when I explained the three door thing. Either that means they are more open-minded or smarter than your English class Mr. OP.

Which seems odd. If anything, it's easier to understand on a large scale. It's easy to imagine the continuum of evolution, of a species slowly changing into something else, of common ancestors sparking so many different variations like a modified blueprint...

For all the nerds out here, try The Blind Watchmaker. I managed to evolve a Space Invader at one point.

Story of my life, and yet my friends will still argue even when it would be better for them to agree. I don't open my mouth and assert facts unless I know they are true. If I don't know something I say that I don't. I am almost never wrong.

The conveyor belt doesn't actually impede the forward motion of the plane. The conveyor belt could be going 100mph and the plane would remain stationary while its wheel spin at 100mph in freespin. As soon as the plane turns on its engines, the propulsion from the engines moves the plane forward, regardless of how fast the wheels are spinning. It will then accelerate to takeoff speed and lift off the conveyor belt.

We were showed that one Monty Hall problem in school. And I didn't get it. Why the fuck would you switch door, the only door you know anything about is the opened one with a goat, how does that have anything to do with your knowledge of the others, the odds are 50/50 after they were 1/3!

The reason people get so bogged down in the goat problem is because no one really understands how to explain the solution. It's usually math minded people who get the solution, and they try to explain it in math terms. But, in reality, the solution doesn't have much to do with actual probability. It has to do with which door you chose and which one the car is in. The host is never going to offer to open your door and he's never going to offer to open the door with the car in it. THAT'S the solution and that's how the probabilities switch.

If people would just say that, we would have a lot more Let's Make a Deal winners.

I'd like to compound the question: what if, when the plane's engine turned on, the conveyor belt increased speed to match the speed of the plane?

Do you understand it now then?
If I understood it correctly, you are indeed wrong and that is the tricky part of that problem.
God I hate statistics.

I would say so. The bullet hits the head with x amount of force, which is equal to the force affecting the head. However, since the head has more mass, the acceleration is smaller than what the bullet has on impact.

I'll try to explain this simply (the picture in the OP helps)

When you first pick a door, the odds of getting the car are 1 out of 3, so the odds are essentialy 2/3 that you have picked a goat at the start.

Then he opens one door and eliminates a goat, this means either the one you have chosen has the car or the last remaining door. But we already know that you're most likely sitting on a goat (2/3), which means it's most likely the car is in the other door. By switching you change the more to likely option (2/3).

If it helps imagine the scenario with 100 doors, one with a car, 99 with goats. You pick one its most likely a goat, then he eliminates 98 goats, leaving the last remaining door to be most likely a goat. It's unlikely to get the car on the first guess,

It doesn't really help much that one of Darwin's most cited examples of natural selection (the dark vs light colored moths, which supposedly developed primarily dark coloration in response to industrialization covering all the trees with with soot) was actually a hoax - the differing coloration had nothing to do with camouflage (the ratio of dark vs light never changed and the moths didn't sit on trees during the day anyways) and the photographer had in fact just glued the moths to the trees to get those pictures.

Nor does the bit where science textbooks from when I was a kid were still teaching evolution 'facts' that were widely known to be completely false when my mother was in school (and of course they were still in her textbooks too).

Let me see if i can explain this simpler that it has. (i didnt understood it at first either)

The only chance of you losing if you switch is if you choosed the correct door the first time.

That was the experiment i was thinking of. I think it wouldn't.

Edit: On second thought, the plane will always move because of the air the turbines expell, unless in adition to the belt the plane is in an air tunel in wich the air will produce the same result that if the plane was moving, how paradoxical.

This, this, this. Even when you win an argument, you lose a lot of respect from said person. Arguing is never effective because even if you can definitively prove you're right, the other person will only resent you for it.

But how do we know that one door is more likely to have a car than the other?

That's nice. It will still run. When the engine is on, there is very little friction between the wheels and the belt. That's WHY a plane will still fly. Unlike a car, which has wheels that push off the ground, a plane moves by pushing off the AIR using the propeller. It would be like asking what would happen if you dragged your hand along a conveyor belt in the wall that matched your speed.
