# What does LC mean?
Oct 30, 2016
LC can mean Light Cylinder.
#### Explanation:
A light cylinder is a theoretical cylinder around a pulsar which is a rapidly spinning neutron star.
The radius of the cylinder is:
$r = \frac{c P}{2 \pi}$
Where c is the speed of light and P is the period of the neutron star.

# Trigonometry: Chords, Arcs and Angles [PDF]
Gerardo Sozio5
Trigonometry, as it is taught in high school using the trigonometric ratios, has an interesting history. Indeed, it is a relatively recent invention, going back roughly to the 1400's, although Arab mathematicians developed essentially the same ideas earlier... | {} |
# What is the bond polarity of h2s?
Dec 24, 2013
The short version: Sulfur is more electronegative than hydrogen, so the $\text{H-S}$ bond is polar with electron density higher on the sulfur atom.
#### Explanation:
This leads to $\text{H"_2"S}$ being a polar molecule.
However, the difference in polarity between $\... | {} |
# Values
Everything that can value, has a value scale. Some people claim to value everything equally (an impossibility with the human architecture, but let's assume they do), and so all values on the scale are the same. I consider that a wrong view to take, because then a human being is no more valuable than an electr... | {} |
# Prove or disprove the given equivalence [duplicate]
f(n) = n/100 = Ω(n) . I am new at proving asymptotic notations , especially at big-Ω. That's why I even didnt start the beginning myself. I tried to prove myself as looking at other proofs and searched on the internet to find same question but I couldnt find. I don... | {} |

# $f \in \mathcal S, f(0)=1$ then $\lim_{\epsilon \to 0} f(\epsilon x) = 1$
Let $f \in \mathcal S(\mathbb R^n)$ with $f(0) = 1$. Here $\mathcal S$ means the Schwartz class. Then how can I prove that $$\lim_{\epsilon \downarrow 0} f(\epsilon x) = 1 \; \text{(compact convergence)} \;?$$

# Why is ice made from boiled water clear?
A common trick to make clear water ice is to boil pure water prior to freezing it. Why does that work and what are the white inclusions in ice that was made from unboiled tap water?
