Calculating Orbits of Groups: SO(3)

Click For Summary
Calculating the orbits of groups, specifically SO(3), involves understanding group actions and their corresponding orbits. An orbit is defined as the set of all images of a point in a group under the action of the group. For example, the orbit of the rotation group SO(2) is a circle. Resources like MathWorld provide additional explanations and examples for further understanding. Clarification on these concepts can help in calculating orbits effectively.

group theory : orbits

hi.

I'm trying to calculate the orbits of some simple groups. I have found many explanations of what they are, but no example calculations. does anyone have any ideas where to look. I'm trying to calculate the orbit of SO(3).

thanks

What in heaven's name is the orbit of a group ?
Could you explain; please ?

group theory : orbits

if you let A be a group and G be an action on that group with a being a point in A. The set of all the images of the permutations of x by g in G on A is the orbit.

and here's the obligatory mathworld link: http://mathworld.wolfram.com/GroupOrbit.html

example : the orbit of the rotation group SO(2) is a circle.

( ... but I've been teaching myself all this, so there is a chance that I am completely wrong)

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
