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.

    I Mass-luminosity relationship for red giants and AGB stars?

    Hello! I'm attempting to find the mass of a red giant and an AGB star. I have their luminosities, radii, and the masses of their cores. I'm looking for some kind of mass-luminosity relationship. Do you know of any, or do you know of a good place to look for such equations? Thanks!

    Wavelength to Frequency Relationship in Musical Notes

    Hi people, So I've been digging into music theory and want to understand the basic reasons for how it is constructed. I've come across a particular relationship but I can't understand the reason it exists. A quick musical lesson: Imagine you've got a pure musical note: let's say C. From a low...

    I Relationship between EM and matter fields in QED

    It seems that QED treats the matter and EM fields as independent yet coupled fields. On the other hand the EM field equations emerge immediately under local change of the phase of the matter field, exactly as required to reestablish local (gauge) invariance. From that perspective it almost seems...

    Great. I will be moving into general relativity next. Before that, I will touch on one more topic: energy and mass, a topic of special relativity, and the formula ##E=m c^2##. There is rest mass ##m_0## (the amount of stuff an object is made off, an invariant) and the inertial mass...

    I E & B field phase relationship in EMR

    Common diagrams for the magnetic and electric field components of EMR show the fields at right angles in space with peaks aligned along the axis of propogation, for example Wikipedia here: https://en.wikipedia.org/wiki/Electromagnetic_radiation. However, Faraday's law says the E field depends...

    I Relationship between Planck Distribution and Quantization of Energy

    I came to understand that Planck Distribution is necessary to explain UV catastrophe. With that necesity in the background, the distribution equation eventually suggests that the energy emitted by black body has discret values. But I wonder how that's related to E=nhv. I understand that "n" also...

    Confused by the relationship of work and kinetic energy

    So the equation for work is W = F * s F = m * a, so W = m * a * s Transferring this to units of measurement gives us: J = kg * m * s-2 * m Or simplified: J = kg * m2 * s-2 Transferring back to units of quantity: W = m * v2 How can that be correct? Obviously Ekin = 1/2 * m * v2. Where did that...

    Relationship between k and E when deriving the density of states

    Number of states in that volume of k-space, ##n(k)dk## is: $$n(k)dk = (\frac{L^3}{4 \pi^3}) \cdot 4 \pi k^2 dk = \frac{L^3}{\pi^2}dk$$. Then the notes state that by defintion, ##n(k)dk = n(E)dE##, and hence $$n(E)d(E) = \frac{L^3}{\pi^2}dk$$. I don't quite see why this is true - isn't it the...
