Who creates the globe/sphere where you can walk inside of and it rotates in place, to track position in a game

it was on discrovery channel (well on daily planet which is on discovery channel) go to the discovery channel website and go to the daily planet section you should find it. That thing was super cool but 50000 for a goming controler is a little out of my leauge. try buying the ddr dance mats for PS2 and play games not ddr its crazy fun tetris is nutty and crash bandacott or spyro the dragon are just insanely fun.

These are called map wheels.

A mag-levs route is lined with magnets and they use the polarity to move -- almost like a model or toy train; except this is done with magnets. They don't come in contact with anything though they do have retractable rubber wheels but those aren't used when they are moving.\n\nEDIT: P.S. Aproov -- anyone can copy and paste...\n\nThere's more info in the below link:

Artificial gravity in space is created using something called centripetal force. Most people call this centrifugal force and assume it flings things outward from the center of motion, but this is a misconception.\n\nWhat is actually happending when you are on a playground merry go round, going through a loop in a roller coaster, or are on a space station of the future, is this:\n\nAll objects, when set in motion, want to go in a straight line. If you attach a clay ball to a string, and swing it around in a circle, and the string breaks, the clay ball does not fly outward from the center of revolution, but it flies out tangent to the radius of the circle from the point that the string broke at. To see what a tangent line is, draw a circle, then pick a point on the line of the circle and draw a staight line....kind of like if you were to draw a ball sitting on a table, the table is tangent to the ball. \n\nSo, once the string breaks the clay ball will no longer go in a circular motion but in a straight line (though here on Earth gravity would have it fall the the floor of course). \n\nNow, the only reason the clay ball travels in a circular motion is because of the string. Every time the ball tries to go in a striaght line, the string yanks it back in a different direction. If you could see the forces at one point in time as this is occuring, you'd see that the force of the string is actually pulling the ball towards the center of motion. This force is called the centripetal force and it is an inward force.\n\nThe same thing applies when you are on a futuristic space station. Though there isn't a string attached to you, your body wants to move in a straight line, tangent to any given point along the circular path you are traveling, and the centripetal force that prevents this is coming from the floor of the space station, pushing you inward towards the center of motion.\n\nIf suddenly the floor were to break away, you'd fly out on a path tangent to that point.\n\nSo, to answer your question, if the space station and core were able to spin seperately, it'd need to be the outer part of the soace station, if I understand your question correctly.

Hi Mooma, I'm thinking it could be the Crystal Maze, does that ring any bells? Even I'm interested to find out although I'm sure it defiantly could be the Crystal Maze.

Initially, the ball is pushed, it slides. There is no rotation, as stated in the problem/question. This means there is no rotation at all. That all the velocity is translational.\n\nFor this scenario think of the ball as a solid block that has been pushed and it sliding across the floor.\n\nAs stared, at some time (t1) the ball begins to roll.\n\nAt this time, the ball's motion is both rotational as well as translational. In other words, it rolls as well as moving forward. This motion is what takes place at the *contact point* of the ball to the floor.\n\nIf the ball rolls, it is not slipping.\n\nIndeed, the friction causes the linear motion to decrease, and eventually stop the ball.\n\nThe rotational motion of the ball is also undergoing friction. A rolling sphere's motion is very subtle and often misunderstood. By virtue of the ball's mass there is a very tiny (tiny is relative to the mass and material) flat spot between the ball and the surface upon which it rolls, whereby a small torque gives rise to a resistance of the motion. This is why a rolling sphere slows. But.....since there is friction, the velocity of translation, is related to that of rotation by the following:\n\nv^2 = 2gh/(1 + I/Mr^2)\n\nWhere M is the mass of the ball and "r" its radius, I its moment of inertia. This is common notation. If there is no rotation, then the moment of inertia term drops out (I = 0) and you are left with a velocity which is strictly that of a translating body......kind of like free-fall.\n\nIf the ball is given one initial push to give it the initial velocity Vo, then unless there is some other forcing function at work, friction will act to decrease the motion of the ball, and all said velocities thereof. None of the velocities will increase.\n\nIf you know of a situation where such a case can exist where the ball increases velocity without doing anything to it.....make sure you mention my name when you pick up the your Nobel Prize.\n\n:)

I am working at a Research Insitute in Artificial Intelligence. We are now researching a brand new technology that may one day erradicate the sedentarism. The unification of matter principle has been used to create a volatile spherical ball a few centimeters in diameter, which can penetrate every kind of material object (think of it as a radiation coordinated though satelite). This has only been experienced on mice, but one day such an object will move with speeds of up to 3m/second on the shorest way towards you. Of course, a pain ensues uppon contact (and maybe some minor tissue damage), so this would make people more active - trying to avoid the sphere.

The referee.  He directs the rest of the activity in the basketball court.\n\n(This is not a very good analogy!  If your teacher is telling you that a cell is like a basketball court, he's a worthless git;  I'd like to see someone use one of these "city" cell analogies to explain mitosis.  LOL).

Here are two (see refs.). Note that the second one is a rotating 3-D model.

Its a bit rounder. The panels on the Teamgeist ball makes it the roundest ball ever produced

Its called the "Teamgeist"

That question makes no sense.  A ball, or sphere, is a 3-dimensional object.  A circle is a 2-dimensional object and doesn't exist in real life.  A ball is not a circle.
