Acetonitrile
Acetonitrile (also known as ACN) is a kind of chemical compound with formula CHCN. It is a clear liquid and is the simplest molecule in a group called nitriles. Acetonitrile is made when plastics are being made so is quite cheap. Chemists use it as a solvent for chemical reactions and in cromatography.
Acetonitrile is flammable and can hurt our eyes.
Ranunculales
Ranunculales is an order of flowering plants. Of necessity it contains the family Ranunculaceae, the buttercup family.
Ranunculaceae
Ranunculaceae is a family of flowering plants also known as the "buttercup family" or "crowfoot family". Members include "Anemone" (anemones), "Ranunculus" (buttercup), "Aconitum" (aconite), and "Clematis".
Interlingue
Interlingue is a constructed language. It was called "Occidental" between 1922 and 1947. Edgar von Wahl, one of the first Esperantists created it. Von Wahl was from the city of Tallinn in Estonia, which was in the Russian Empire but later became its own country. He spoke German, Russian, Estonian and French since he was a child and had natural ability in languages. He is often called "de Wahl".
Interlingue looks a lot like languages in the Romance language family: French, Spanish, Italian, and so on. De Wahl made a rule called De Wahl's rule that made changing verbs to nouns easier and more regular. For example, the word exploder (to explode) regularly changes its d to s (making explosion) when following this rule.
De Wahl was not happy with Esperanto. He decided to create a language called "Occidental". He published it in 1922. In 1949 the name of the language was changed to "Interlingue".
There were already many types of constructed languages during de Wahl's time. Some of them, like Esperanto and Ido, were called "schematic" because they followed their own design. Others, like Latino sine flexione and Idiom Neutral, were called "naturalistic" because they tried to look like natural languages. The difficulty was that creators had to choose between being regular or looking natural. Louis Couturat, the creator of Ido, wrote the same thing in 1903, and called it a paradox: "The international words are not regular, and the regular words are not international." The language that de Wahl made was meant to be a language that was both regular and international at the same time.
Because de Wahl announced his language in the magazine Kosmoglott in 1922, this is where the Occidental activities can be seen. However, de Wahl started making the language long before this. In between 1906 and 1921 he started experimenting with his own language, and it changed a lot. At the time he called it Auli, or "auxiliary language" (auxiliary means helpful). The other nickname for Auli is proto-Occidental (which means "old Occidental"). When de Wahl announced his language in 1922, it was almost but not quite done. He actually wanted to wait a bit longer, but there was big news in 1921: the League of Nations was looking at the idea of an international language. De Wahl had also sent a letter and got a positive reply from the League of Nations in September 1921.
Commitment scheme
In cryptography, a commitment scheme is a way for a someone to tell something to someone without letting other people know. Someone would do this to make sure they can prove who they are. Someone also might do this to make sure that someone does not cheat.
This is done by using a one-way function to change a string into a hash. This is called the "commit phase". Later, if someone needs to prove that they were the one who made the commitment, then they can tell people the original string they used. This is called the "reveal phase".
One-way function
In cryptography, a one-way function is a function that is very simple to compute (figure out) in one direction. There is a series of instructions that can be simply and easily applied to an input to give a complicated output. However the reverse of going from the output to the input is made to be as difficult as possible.
SHA hash functions
In cryptography, the Secure Hashing Algorithms are a group of cryptographic hash functions released by the National Institute of Standards and Technology (NIST). The algorithms take an input and produce a "hash" value (often shown in hexadecimal). The length of the "hash" depends on the digest length of the algorithm.
The Secure Hashing Algorithms, being Federal Information Processing Standard (FIPS) compliant algorithms are subject to the Cryptographic Algorithm Validation Program
Border Gateway Protocol
The Border Gateway Protocol (BGP) is the main routing protocol of the Internet. It decides how data gets from one place to another on the Internet. It was made to get rid of the EGP routing protocol to make the Internet more independent.
Most Internet users don't use BGP. It is the ISPs who use it to talk to other ISPs so they can send and get data from each other. It is one of the most important protocols of the Internet.
GPRS Tunneling Protocol
GPRS Tunneling Protocol (GTP) is a group of protocols to send and receive data over cellular phone networks.
Power metal
Power metal is a type of heavy metal music that mixes traditional metal with thrash metal or speed metal. There are two types of power metal. One comes from North America that sounds more like speed metal, and a more popular one from Europe (especially Finland, Germany, Italy, Scandinavia) and Japan that usually sounds happier and usually uses keyboards. It is usually characterized by high, clean, melodic vocals, fantasy based lyrics as well as complex and fast lead guitar solos.
Some of the most popular European style bands include:
Defense Support Program
The Defense Support Program (DSP) is a group of satellites that orbit the Earth. They are owned by the United States Air Force to run the "Satellite Early Warning System" used by the United States. DSP satellites are used to detect missile and spacecraft launches. DSP is also used to detect nuclear explosions. It does this by using infrared sensors on the satellite.
Blackheath
Blackheath can be any of the following:
Blackheath, Surrey
Blackheath is a village in Surrey near Guildford.
Bandipur National Park
Bandipur National Park is a national park in India. It contains Gaurs and Asian Elephants, as well as tigers. In 1973 it was decided that Bandipur National Park would be protected as a place for tigers to live safely, as part of a project called 'Project Tiger'.
The national park has an area of 874.20 km.
Urban legend
An urban legend is an often circulated story that is not necessarily based on truth, but merely conjecture and rumor. However, there may or may not be a grain of truth from which the story originated.
The Internet has made it easier for urban legends to spread, as people often spread them to their friends or family using e-mail. As a result, some websites such as Snopes.com and TruthOrFiction.com, among others, have been made that look at urban legends and try to see whether or not they are true.
