Did you know about tube false mri scans that surgeons use for spine space disc measurements which can cause the high rate of Failed Back Surgery http://tinyurl.com/34bg4a Now upright spine disc space measurements are more accurate http://tinyurl.com/fqb67 more info. http://tinyurl.com/9s5hu would you challenge your Dr. if he wants you to get a tube mri scan ? vs a upright mri scan that rountley finds the complete pathology that tube mri scans overlook

I was just reading that there is a repulsive force to gravity that may be responsible for the universe expanding at an increasing rate. Doesn't this make Gravity Dipolar, like magnetism? Maybe the poles aren't oppositely aligned, and the force is a different type of field, but if that is right, it is an interesting point.

There is a quest to understand all these forces, to work them together into one "unifying theory." I believe the only way to get this theory to work is to try things that seem like scientific heresy, like finding the ways the gravity and magnetism are similar. Everyone is so convinced that gravity can't possibly have anything in common with magnetism, but they are looking for ways to unify them! That makes no sense!!! They have to be related somehow or there is NO way to unify the theories!

Correct me if I'm wrong, but if there is a unified theory, wouldn't that allow us to mathematically see the relationship between the forces?

Thoughts?

Construct one function (call it f) with all of the following properties:

i) f has exactly one vertical asymptote located at x=(3/2)
ii) f has an oblique asymptote at y=18x+28
iii) f has exactly two roots, both of which are non-real
iv) f has exactly two point discontinuities, one at x=(4/3) and one at x=-15/2)
v) f has a y-intercept at (0,-1)

Project Criteria: The size of a shoe box. ~The protection for the egg must be engineered, not just filled with stuff.~No type of packing material will be allowed. This includes but may not be limited to such items as : bubble wrap, cotton balls, tissue , styrofoam pellets, cronstarch pellets, pillows, stuffed animals, shaving cream, paper, ballons or egg crate foam. No type of food may be used as packing material. This includes : jello, marshmallow, popcorn, or peanut butter,~ No wooden or metal boxes~No parachutes or helium filled balloons will be allowed~The egg will be provided at the time of the drop which you will then have to insert it into your project~ No boxes will be accepted that are preloaded with an egg. And it must have physics behind the design. Including Newtons laws of motion, terminal velocity, momentum, and gravity.

Thanks for the help ahead of time.
