What is Relationship: Definition and 1000 Discussions

An intimate relationship is an interpersonal relationship that involves physical or emotional intimacy. Although an intimate relationship is commonly a sexual relationship, it may also be a non-sexual relationship.
Emotional intimacy involves feelings of liking or loving one or more people, and may result in physical intimacy. Physical intimacy is characterized by romantic love, sexual activity, or other passionate attachment. These relationships play a central role in the overall human experience. Humans have a general desire to belong and to love, which is usually satisfied within an intimate relationship. Such relationships allow a social network for people to form strong emotional attachments.

    Relationship between "Coriolis Effect" and "Gold Ratio"?

    A common claim that hurricanes and cyclones have geometrical proportions that resemble a logarithmic golden spiral. Knowing that cyclones and hurricanes rotate because of the well-known Coriolis Effect, is it possible that the Golden Ratio is just a natural manifestation of the Coriolis effect?

    Is space an entity, a relationship or a concetual framework?

    Hi, the first paragraph in the Wikipedia entry to space contains a sentence saying there is disagreement between PHILOSOPHERS whether space is an entity, a relationship or a conceptual Framework. I am interested in what PHYSICISTS think about this. My personal view is that it is an entity as...

    The relationship between F=ma and E=mc2

    I'm wondering about the relationship between F=ma and E=mc2. Is it simply that, at relativistic speeds, E=mc2 replaces F=ma? (much like D = v x t is replaced by the Lorentz Contraction at relativistic speeds)

    Fascinating number theory relationship

    Recently I noticed something odd about the triangular numbers. The basic definition is \displaystyle\sum_{x=1}^{n}x=T_n A short time after playing around with T_n values I discovered something very odd-another formula for triangular numbers involving the root of the sum of cubes from 1 to n...

    General relationship between gravity and rocket design.

    I was pondering Mars missions and wondered about what kind of vehicle an astronaut on Mars would need in order to get home. My first thought was that Mars gravity is .38 that of earth, so he would need a rocket about 38% as large to get off of Mars as he needed to get off of earth, This of...

    Regarding the relationship of mass, velocity, and time

    Perhaps someone can clarify something for me that's been bugging me for a while. Assuming that singularities are not a singular event but occur naturally, we believe the objects for be of infinite density and infinite heat. On the other hand, in the case of black holes, it's logical to assume...

    Relationship between Mach number and Reynolds number

    Is there any correlation between Mach number and Reynolds number? Both of these nondimensional numbers involve speed, but they don't seem all that related other than that. For high speed flow, we have high Mach number. Is it incorrect to say that "generally" high speed flow is turbulent?
