The central atom is in the centre of the triangle, with the ends of the electron clouds at the corners of the triangle. The non-bonding pair of electro... | {} |

# Poynting vector
Dipole radiation of a dipole vertically in the page showing electric field strength (color) and Poynting vector (arrows) in the plane of the page.
In physics, the Poynting vector (or Umov–Poynting vector) represents the directional energy flux (the energy transfer per unit area per unit time) or pow... | {} |
Simple (postscript) printer setup in OpenBSD 4.3
Printing in UNIX may sometimes be somewhat of a hurdle. This is also very dependent on which type of setup you want (local or remote and which software to use) and which type of printer you have.
In general you need; a properly configured printer driver towards the pri... | {} |
# Can O2 combine with H2 to form water without activation energy?

Let say that I have hydrogen gas and oxygen gas mix together, is there any chance that some H2 and O2 will react to form water without doing anything to it? I know that there needs to be activation energy to start the rea... | {} |
# Bounding the “spikiness” of a probability distribution
Are there any well-known conditions that guarantee that a probability distribution isn't too "spiky"?

Given a function $$f(x)$$ and $$\frac{\partial f(x)}{\partial x_i}=\frac{f^2(x1,...,x_i+\pi/2,...,x_n)-f^2(x1,...,x_i-\pi/2,...,x_n)}{f(x)}$$. When $$f(x)\to0$$, $$\frac{\partial f(x)}{\partial x_i}$$ could be infinitely large. ($$f^2(x1,...,x_i+\pi/2,...,x_n)-f^2(x1,...,x_i-\pi/2,...,x_n)$$ is always non-zero)

67.14 Devissage of coherent sheaves
This section is the analogue of Cohomology of Schemes, Section 30.12.
Lemma 67.14.1. Let $S$ be a scheme. Let $X$ be a Noetherian algebraic space over $S$. Let $\mathcal{F}$ be a coherent sheaf on $X$. Suppose that $\text{Supp}(\mathcal{F}) = Z \cup Z'$ with $Z$, $Z'$ closed. Then ... | {} |
