Ok he's a freight-train but some of those pivots were incredible too !!

Now, now Greogory, troll is convenient label for all manner of folk who use the internet like crack cocaine....

I must concur with the spider not playing a pivotal role in the bio-train. If this project were halted by otters, snakes, owls, mice or beavers I could understand the fuss....Hell, even fleas or mosquito threatened would be cause for major alarm but a rare species of fucking arachnid?? Stomp that squishy, worry about the karma later, and build the fucking bypass!

....unless some arachnologist can find a biochemical compound it produces that cures cancer maybe....or maybe repairs livers "I dunno, JUST DON'T SQUASH IT!!"

ecstatic states. focus. the unwobbling pivot.

This sufi dancer is known as a Whirling Dervish, and this dance is a form of dhikr (or remembrance of God) among a Persian Sufi order known as the Mevlevi. They are followers of Rumi, a 13th-century poet and among one of my favorite poets of all time.

How can he -not- fall over?

Ok, so some cultural illumination seems like a good idea about now.

A battered sav: A sausage covered in batter then deep fried. The idea here is that the gymnasts penis is a sausage being dipped in batter and/or the method of cooking the battered sav into boiling oil as he drops towards the ground.

Party/crazy date: Date is an anus. The Party/crazy date, when one pivots and spins flashing his date for all to see.

Spinning date: A backflip.

Hello boys: This is where the gymnast opens his legs and seemingly presents his testicles. Onlookers would no doubt say, in the Carry On tradition, "Hello boys".

Flatbag: bag meaning scrotum. Self-explanitory.

A bit of a goose: A goose means a fool. To be "a bit of a goose" means to have done something a little foolish or embarrassing. This is used when the gymnast performs what looks like a goosestep ala Nazi soldiers.

Hope this helps without being condescending.

Went to Magic Mountain in CA years ago and got on a ride similar to this, except it was the giant Viking Ship/Space Shuttle, etc which swung back and forth, as well as up and over. This type of ride has two sides of passengers facing each other, blocked by a central wall (where the pivot arm is attached). As we went up and over, although we couldn't actually see the people on the other side, we could tell that they were spitting, potentially covering people on our side with spit once we swung back down. Everyone was getting pissed and yelling at them to stop. Once the ride ended, we all piled out, ready for a fight, only to be greeted by an army of green-faced, empty-stomached Japanese tourists exiting the other side of the ride. So, yeah....it wasn't spit...

This plane is balanced on a pivot point. It doesn't take much to tip it.
Not once does it leave the ground.

Really, it's just an example of incompetency as aircraft should be tied down when not in use.

May I suggest replacing the embed with this clip which includes the "Pivot questions".

You can always use the 'start' param in the embed code to skip O'Donnell's intro.

Shameless self *promote on what I see as the pivotal discussion of our time.

pilot error. not enough altitude and he didn't execute the maneuver very well - the chopper should have pivoted around at the end of the upward curve and straighten itself in the direction of flight thus giving the rotors a chance to provide lift as soon as possible before it starts loosing too much height. altitude of the terrain was also a factor, but the pilot should have calculated that in ...

Lesson here is to kiss cop ass alt all costs. I always do, even if those costs are my freedom, dignity or human rights. I will gladly submit to the position of circle jerk pivot man if told to do so.
If they pepper spray my mom though, I will get a punch in if it's the last thing I ever do.


With these cops "getting a punch in" might actually be the last thing you do.

This whole situation is retarded, if they suspect the guy is drunk, breath test him. If they feel he was driving dangerously, regardless of alcohol level, arrest him for that. The whole "sobriety test" thing you have in the USA seems like a throwback. I mean, I know it's a dirty word but use some science for fucks sake.

Either way there's no call to taser him and certainly no call to pepper spray his mom.

Not caused by being either drunk, or clumsy. Merely stupidity (admittedly though, potentially caused by drunken clumsiness)
I watched this a couple times and thought to myself "Hell, I've jack-rabbited my bike a more than a few times, why the hell did he get so much air on a wheelie right away?"
Upon closer inspection, I realized he's sitting stupidly far back on his bike, and if you watch in full screen it becomes clear that he's actually sitting on his passenger seat. Meaning that his center of mass is located directly above his rear wheel, the one that gives the power. After that it just becomes simple pivot physics.
jack-rabbiting, taking off very quickly from a dead stop.


Aye. Noticed he was sitting WAY too far back from the get go. What a knob

A mechanical gyro causing the movement would have delay and the balls would roll slightly. Assuming the table is above the ship's roll centre, the table would have to over correct for the ship's movement in order to keep the balls exactly in place. Most likely electronic gyros and good hydraulics with no stiction and powerful enough to not be affected by players putting pressure on the table.

Not really. Not saying it wouldn't be expensive, but the technology to do this has been around for a while: a few accelerometers, a gyroscope, and lots of actuators. And someone who knows a little control system programming.
Still pretty cool though.>> ^Spacedog79:
To work that precisely must take some serious engineering. I bet they're really expensive!


Actually, and judging by the title it is what it uses, but this can pretty much be done with a pivoting table and a large spinning gyro placed in the table. Much like a top, the spinning gyro would resist movement. There is probably something else that auto corrects the tilt for any time it is off (a gyro resist forces that try and tilt it, but if it finds a new tilt degree forcefully, it will keep it). It is really hard to tell from just seeing this video. Also if you went with the actuator route, something as simple as the actuators and an ipod alone could be used.
the most expensive part would probably still be the pool table, and the act of building the pool table mounted to the auto level device.
