I'm reading the book of Silverman about elliptic curves. It describes the function field of a variety defined over K to be the quotient field of K[X]/I(V), then says that we may look at the function field of P^n (projective n-space) as the subfield of Kbar(X_0...X_n) consisting of ... | {} |

Abstract
Proving fixed point theorem in a fuzzy metric space is not possible for Meir-Keeler contractive mapping. For this, we introduce the notion of $c_0$-triangular fuzzy metric space. This... | {} |

Standard Error For Difference
Contents
Is it good to call someone "Nerd"? The standard deviation of the means of those samples is the standard error. We calculate the mean of each of these samples and now have a sample (usually called a sampling distribution) of ... | {} |
# \@startsection, hyperref and newunicodechar; protection needed?
When working with custom defined environments using \@startsection I found, after switching to newunicodechar for defining my unicode characters, that the sectioning headings give this peculiar output:

# Sorting Table Column
Suppose I have a table with say two columns. How can I sort its rows based on the first column? Is it possible in latex? If I do it in another application (like MS Excel) can I import the data from my worksheet into a tabular?
I would be very happy if you suggest me a way to handle this sorting,... | {} |
# [DR011] Neural Turing Machine

This popular work combines traditional neural network with an extra memory. By controlling the read heads and write heads, the network, or controller, is able to store and retrieve information from the memory. The memory accessing resembles Turing Machine writin... | {} |

# Finding Average Rate of Reaction
## Finding Average Rate of Reaction
Rate of reaction is a measure of how fast a reaction occur, or how much the reactant/product change in a period of time.
Rates of reaction = Quantity change of reactants/products Total time for the reaction
Example
In a chemical reaction, 2.5g of... | {} |

# Blackjack, what are the chances?
To start the game of Blackjack, players are dealt two cards at random from a shuffled deck.
You write the following code to simulate the act of dealing an initial hand. To test the code, you deal a hand $10^6$ times and record the number of times the player makes Blackjack on their ... | {} |
