List of purification methods in chemistry
Purification in a chemical context is the physical separation of a chemical substance of interest from foreign or contaminating substances. Pure results of a successful purification process are termed isolate. The following list of chemical purification methods should not be considered exhaustive.

Etymology of chemistry
In the history of science, the etymology of the word chemistry is debatable. It is agreed that the word derives from the word alchemy, which is a European one, derived from the Arabic al-kīmīā (الكيمياء). The Arabic term is derived from the Greek χημία or χημεία. However, the ultimate origin of the root word, chem, is uncertain.
According to the Oxford English Dictionary, the majority theory is that al-kīmīā is derived from χημία, which is derived from the ancient Egyptian name of Egypt (khem, khame, or khmi, meaning "black earth", contrasting with the surrounding desert.) Therefore, alchemy is the "Egyptian art". However, it is also possible that al-kīmīā derived from χημεία, meaning "cast together".
Traditionally, the science of alchemy was once considered to have sprung from great Egyptian figure named by the Greeks "Hermes Trismegistus" (the "thrice-great" Hermes, celebrated as priest, king, and scholar), who is thought to have been the founder of the art. Reputed to have lived about 1900 BC, he was highly celebrated for his wisdom and skill in the operations of nature. In 1614 Isaac Casaubon demonstrated that the works attributed to Hermes – the so-called "Hermetic corpus" – were actually written pseudonymously during the first three centuries of the Common Era.

List of The New Batman Adventures episodes
Three years after the second season of Batman: The Animated Series ended production, the show was moved (as The New Batman Adventures) from Fox to The WB channel, which was airing and producing Superman: The Animated Series. These shows were merged as part of an hour-long segment called The New Batman/Superman Adventures. The WB wanted more episodes of Batman, so 24 new episodes were produced, which featured a different format and more focus on Batman's supporting cast.
In addition to the network's demands, the producers decided to make the show match the graphic style of Superman: The Animated Series, so all the characters and objects were redesigned as more "animation friendly" with fewer lines, usually referred to by the fans and creative staff as the "revamp" (or alternately, the "new look"). A similar graphic style was used in the rest of the DCAU later on.
The DVD box set of the series is labeled Batman: The Animated Series – Volume Four (from The New Batman Adventures), most likely to establish the connection with the original series.

Chemistry (Smash)
"Chemistry" is the sixth episode of the American television series, Smash. The episode aired on March 12, 2012.
Plot
Ivy (Megan Hilty) comes down with laryngitis, Julia (Debra Messing) keeps bumping into Michael (guest star Will Chase), Eileen (Anjelica Huston) and Ellis (Jamie Cepero) talk at a bar, Karen (Katharine McPhee) performs for a bar mitzvah.
Production
Recurring guest stars include Will Chase as actor Michael Swift.
One of the cover songs already announced is "Shake It Out" by Florence + the Machine performed by Katharine McPhee. Additionally, "History is Made at Night" performed by Megan Hilty, Chase and the cast of Marilyn will make a reappearance in this episode, having first been heard in the episode "The Cost of Art", and Hilty's solo version of "Let Me Be Your Star" first heard in the pilot will be heard in the episode. Also, Hilty's version of Jessie J's "Who You Are" was also in the episode. Only "History is Made at Night" was made available as a single on iTunes.

Flight dynamics
Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.
In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.
Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.
Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.

List auf Sylt
List auf Sylt (known as List until 31 December 2008) is the northernmost municipality in Germany, located on the North Sea island of Sylt close to Denmark in the district of Nordfriesland in the state of Schleswig-Holstein.
Etymology
List derived from the Middle Low German Liste (ledge, bar or edge).
History
List was originally a Danish settlement. It was first mentioned in 1292 (Lystum). The original village was destroyed by the great flood of 1364. The settlement was rebuilt further east from the previous location. In the mid-15th century, a church named St. Jürgen was mentioned. In a treaty of 1460, Schleswig and Holstein were linked to the Danish crown, but List remained part of the royal enclaves, small areas of the Kingdom of Denmark situated within the Duchy of Schleswig, but directly controlled by the Danish king.
From the 16th century, the people of List mostly made a living from Oyster farming, raising sheep and collecting and selling gull eggs. At the time, List was an important protective anchorage. In 1644, a Swedish-Dutch fleet of 26 ships commanded by Admiral Thijssen was attacked in the Lister Tief and defeated by Danish ships commanded by king Christian IV of Denmark. The anchorage north of today's town was named Königshafen to honour this event.

Jousting
Jousting is a martial game or hastilude between two horsemen wielding lances with a blunted tips, often as part of a tournament. The primary aim was to replicate a clash of heavy cavalry, with each opponent endeavoring to strike the opponent while riding towards him at high speed, if possible breaking the lance on the opponent's shield or jousting armour, or unhorsing him. The joust became an iconic characteristic of the knight in Romantic medievalism. Jousting matches were notably depicted in Ivanhoe(a novel).
The term is derived from Old French joster, ultimately from a Late Latin iuxtare "to approach, to meet". The word was loaned into Middle English around 1300, when jousting was a very popular sport among the Anglo-Norman knighthood. The synonym tilt dates ca. 1510.
Jousting is based on the military use of the lance by heavy cavalry. It transformed into a specialised sport during the Late Middle Ages, and remained popular with the nobility both in England and Germany throughout the whole of the 16th century (while in France, it was discontinued after the death of King Henry II in an accident in 1559). In England, jousting was the highlight of the Accession Day tilts of Elizabeth I and James I, and also was part of the festivities at the marriage of Charles I.

The Origin of the Elements
The world around us is made of atoms. Did you ever wonder where these atoms came from? How was the gold in our jewelry, the carbon in our bodies, and the iron in our cars made? In this lecture, we will trace the origin of a gold atom from the Big Bang to the present day, and beyond. You will learn how the elements were forged in the nuclear furnaces inside stars, and how, when they die, these massive stars spread the elements into space. You will learn about the origin of the building blocks of matter in the Big Bang, and we will speculate on the future of the atoms around us today.

In fantasy stories, charlatans in fancy robes promise to turn lead into gold. But real alchemists weren’t just mystical misers. They were skilled experimentalists, backed by theories of matter.
And they played a huge role in the development of knowledge about one of our fundamental questions: “what is stuff?”

Dr Stephen Wilkins discusses the origins of the chemical elements. Almost all the elements have an origin in astrophysics from the Big Bang to neutron stars.
A lecture by Dr Stephen Wilkins, University of Sussex
07 November 2019 6PM GMT
https://www.gresham.ac.uk/lectures-and-events/periodic-table-150
In this talk, coinciding with the UNESCO International Year of the Periodic Table, Dr Wilkins will discuss the astrophysical origins of the chemical elements, almost all of which have an origin ranging from the big bang, to exploding white dwarfs, the collapse of massive stars, and the merger of ultra-compact objects, neutron stars. This final mechanism is responsible for many of the heaviest and rarest elements including gold, silver, and uranium, and was only recently confirmed through observations of a merger event first identified using gravitational waves.
Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters. There are currently over 2,500 lectures free to access. We believe that everyone should have the opportunity to learn from some of the greatest minds. To support Gresham's mission, please consider making a donation: https://gresham.ac.uk/support/

The word SCIENCE is derived from a Greek word 'Scio' means to know.Science is associated primarily with the attempt to know something that is to acquire knowledge. It is the part of human nature to try to understand our ENVIRONMENT and also around us what changes are going on.
Compelled by the natural instinct, we explore the space outside our bodies. Outside our body the immediate thing around us is EARTH.Beyond the earth there is the SUN,the MOON.Beyond them there is our solar system.Beyond the solar system it is the UNIVERSE. And beyond the universe, as per our limited knowledge who knows what is there.

The world around us is made of atoms. Did you ever wonder where these atoms came from? How was the gold in our jewelry, the carbon in our bodies, and the iron in our cars made? In this lecture, we will trace the origin of a gold atom from the Big Bang to the present day, and beyond. You will learn how the elements were forged in the nuclear furnaces inside stars, and how, when they die, these massive stars spread the elements into space. You will learn about the origin of the building blocks of matter in the Big Bang, and we will speculate on the future of the atoms around us today.
Speaker: Dr. Edward Murphy, University of Virginia

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
In the history of science, the etymology of the word chemistry is debatable. It is agreed that the word derives from the word alchemy, which is a European one, derived from kimiya (كيمياء) and alchemy al-kīmiyāʾ (الكيمياء). The Arabic term is derived from the Ancient Greek χημία khēmia or χημεία khēmeia. However, the ultimate origin of the root word, chem, is uncertain.According to the Oxford English Dictionary, al-kīmiyāʾ is derived from χημία, which is derived from the ancient Egyptian name of Egypt (khem or khm, khame, or khmi, meaning "blackness" Therefore, alchemy is the "Black Art". However, it is also possible that al-kīmiyāʾ derived from χημεία, meaning "cast together".
