### Moving a Mandelbrot couch around a corner.

You have a rigid Mandelbrot set shaped couch and you want to move it around a 90 degree corner hallway where the width from the corner to one wall equals the

### Re: Birthday cake

You can assume the candles are mathematical points and none is at the exact center so the probability of a cut intersecting a candle is zero. Mark

### Re: Birthday cake

Is it allright if any of the cut splits a candle in two - equal or unequal - pieces? What if the unlucky candle is green?Tofique Fatehi tofique.fatehi.US

### Re: Ocean planet with humongous fish

When I posted this, I was thinking along the lines that gravity causes mass to be bouyant within the field. The fish are denser, but their own momentum around

### Birthday cake

Seems like no one came up with the "easy" solution to my birthday cake problem. Hint: it doesn't require any calculus or equations. ********** A round cake is

### Re: Ocean planet with humongous fish

The fact that swimming too slow makes them fall towards the center, makes me think the fish are denser than the water. I'd think the gravitational forces

### Compound cog in non uniform field of symmetric objects

I've been working on this problem for the past week. In an Archimedean uniform gravitational field, with an equilateral triangle, divide it in two equal parts

### Re: Point mass center of gravity in non uniform fields.

My first explanation was correct. I said "the centroids of the fulcrums is the center of gravity of the points". I need to clarify this. In my original

### Re: Point mass center of gravity in non uniform fields.

This is a little more complex than what I originally posted. More construction involvement. If the complexity for a normal construction of the centroid for 3,

### Amendment to my last post

If the summed vectors v1 and v2 meet at point C1 and v1+v2=v3 at point C1, rest of these summed vectors from C2 to C(n-1) when all summed at the point CoG,

### Point mass center of gravity in non uniform fields.

I'm gonna give a crack at this before I forget. Please forgive me that I don't know all the terminology, but I'll try to make it as clear as I can. If V(v)=Av

### Vector magnitude scaling operator V and general centroids in gravita

Define the operator V(v) as a vector magnitude scaling of v by the scalar function of V. Example 1) If the vector v1 has a magnitude ||v1|| and V is a scalar

### Re: Inverse vector (clarification)

Maybe a "vector magnitude inverse"? Is there already a name for this? Since if A1=||E||/(||v1||^2) and A1v1=v2, the inverse magnitude of v1 with respect to
