2. Earth mover's distance - Wikipedia

   en.wikipedia.org/wiki/Earth_mover's_distance

   Earth mover's distance. In computer science, the earth mover's distance (EMD) [1] is a measure of dissimilarity between two frequency distributions, densities, or measures, over a metric space D. Informally, if the distributions are interpreted as two different ways of piling up earth (dirt) over D, the EMD captures the minimum cost of building ...

3. Hiring Movers? This Is How Much to Tip Them - AOL

   The answer depends on your move. The general rule of thumb is to tip your movers 15 to 20 percent of the total cost of the move. For example, if your invoice comes to $2,000 altogether, you should ...

4. Wasserstein metric - Wikipedia

   en.wikipedia.org/wiki/Wasserstein_metric

   In mathematics, the Wasserstein distance or Kantorovich – Rubinstein metric is a distance function defined between probability distributions on a given metric space . It is named after Leonid Vaseršteĭn. Intuitively, if each distribution is viewed as a unit amount of earth (soil) piled on , the metric is the minimum "cost" of turning one ...

5. Comoving and proper distances - Wikipedia

   en.wikipedia.org/wiki/Comoving_and_proper_distances

   Comoving distance and proper distance. Comoving distance is the distance between two points measured along a path defined at the present cosmological time. For objects moving with the Hubble flow, it is deemed to remain constant in time. The comoving distance from an observer to a distant object (e.g. galaxy) can be computed by the following ...

6. Hubble's law - Wikipedia

   en.wikipedia.org/wiki/Hubble's_law

   (The numerical value of the Hubble length in light years is, by definition, equal to that of the Hubble time in years.) The Hubble distance would be the distance between the Earth and the galaxies which are currently receding from us at the speed of light, as can be seen by substituting D = cH −1 into the equation for Hubble's law, v = H 0 D.

7. Geographical distance - Wikipedia

   en.wikipedia.org/wiki/Geographical_distance

   t. e. View from the Swabian Jura to the Alps. Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.
