It's not the force, it's the vacuum. Did you properly make a seal with your hand when you hit it? And did you bring it up to your hand, or bring your hand down to it?

took me a few tries, but I got it. Thanks for pointing it out, haha!

You could stalk them through their past posts and find personal information. Then if you have enough information, you use Google to find them. Or you pose as a potential friend, contract them, and learn more about them. Or you find places like school or church and image-match with a selfie they've taken, if they've posted one. Or you find someone who knows someone who knows someone who's friends with the website's team and ask them for a favor and get the IP address from them. Or you straight-up crack the site. There's other paths, too. For example, if I track back through your posts, you're pretty good at leaving your personal info vague, so I'd probably try to find other accounts you have online and check for more info there and/or hire some Anonymous members to do the cracking for me. If I didn't mind wasting weeks obsessing over you and collaborating with people I see as internet terrorists, that is. Which I do. It all depends on what you're willing to do.

It's generally not worth the time and energy, though, so unless you really, really piss someone off, or you've got a really, really obsessed stalker, the internet's still anonymous enough.

To a point. It basically operates on the principle of conservation of momentum. That is, the speed of the ball bearing hitting the magnet will be the speed of the ball bearing that leaves the chain. The magnets increase the speed by pulling on the ball bearings, and that's how you get up to speeds faster than you would by just flicking the ball bearing with your finger. I don't know at what point, if at all, the ball bearing would be going too fast for the magnet to really add any bonus, but adding more at least shouldn't make it slower. You'd need to upgrade to a yardstick, however.

Step 3) tape the magnets down
Step 4) roll the free ball bearing at the first magnet. When it hits, momentum is conserved, and the ball bearing on the end of the chain is knocked free and instantly sucked to the other magnet. When it collieds, the ball bearing on the end of that chain will be knocked free, and the physics continues from there until the final ball bearing is launched off the ruler.
Step 5) Don't shoot your eye out.

Just look up "Gauss Gun." Or I can give you a reaaaaaally simple one right here.
Step 1) Get a ruler, four magnets (not quite as big as the width of the ruler), ten metal ball bearings (about as big as the magnets), and some tape.
Step 2) configure the magnets and ball bearings on the ruler like this ([]=magnet, O=ball bearing)
O []OO []OO []OO []OOO
They should be spaced so that the last ball bearing in each chain is being pulled by the other magnet, but not quite strong enough to rip it from the ball bearing it's currently magnetized to, and the last ball bearing on the end is near the edge of the ruler

Again with that "the Bible said this common everyday thing is wrong too" argument! Hasn't anyone explained yet the history of the Bible, why those rules are there, how Jesus's sacrifice caused some of them to be "done away," and basically why comparing "God said homosexuality is wrong" to "God said eating shrimp is wrong" is comparing apples and oranges? You can support equality, but please use a valid argument! Try "the intent of 'freedom of religion' is based in letting people live how they want to as long as it doesn't threaten others. You're free to believe what you want about those with non-heterosexual sexualities, but that doesn't give you the freedom to persecute them." Or "God also taught forgiveness and loving your neighbor. None of His teachings requires you to be a jerk towards sinners." Or you can go for an insult: "even if you think they're going to hell, if you decide to make their life a living hell by squashing their rights, that must make you the devil."

I was referring to how Saints Row gameplay lets you punch cars and send them flying. But now that you mention it, that does look like Elizabeth doing the punching.

dddddddd, he didn't bash others for being obsessed with it. He was talking about the book.

True, but the timing kinda sent another message. It happened after American diplomats were refused by China, and right after Obama set new economic sanctions on Russia for their role in the Ukraine conflict. Basically, China said "you're not powerful anymore" and Russia said "oh cute, you're going to intimidate us a couple pennies at a time? Here's our reply: we're getting richer!"

This has nothing to do with gender and everything to do with a scumbag getting comeuppance.

"love hungry people"
You just described everyone ever. That's why everyone's obsessed with it. That doesn't mean it's good (I haven't read it yet, so I can't give my personal opinion), but it does explain why it's popular.

Assuming that "log" is the common logarithm (base 10) and that the angle is in radians, x=1.160501. I cheated, though, and used a graphing calculator once I got it down to -12xlog(x+1/4)=tan(x+4). Summer has blitzed my mind and I've forgotten the necessary calculus to solve this completely by hand. (I'm pretty sure calculus can solve it, at least.)

I'm glad I stopped on a whim to read this single comment. I haven't audibly laughed from a comment in a long time! Good on you, sir/ma'am!

As different guest, I personally think that the person who made this post wanted to find a way to call a two-dollar coin by its amount. Two bucks.
