Collegium Musicum is a Slovak art rock band formed by Marián Varga in Czechoslovakia in late 1969. The band is reformed in 2008 and still plays.
Double bond
A double bond in chemistry is when two chemical elements are joined together in a chemical bond and share four bonding electrons instead of the usual two. The most common double bond is between two carbon atoms, and can be found in alkenes. There are many types of double bonds, such as in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In skeletal formula the double bond is shown as two parallel lines (=) between the two joined atoms. When this formula is printed, the equals sign is used.
Double bonds are stronger than single bonds and double bonds are also shorter. The bond order is two. Double bonds are also electron-rich, which makes them more reactive.
The two pairs of electrons involved in the bond do not behave in exactly the same way. One pair of electrons forms a stronger "sigma"bond, noted by σ and drawn as a straight line between the nuclei of the bonding atoms. While the other pair form a pi bond, π, drawn as two cloud-like areas where the electrons exist, as "orbitals".
Magny-Cours
Magny-Cours is a commune in the Nièvre department in central France.
It is best known as the home of the "Circuit de Nevers Magny-Cours", a famous Auto racing circuit. It formerly hosted the Formula One French Grand Prix. A campus of the Institut supérieur de l'automobile et des transports is also located on the city.
I Wanna Go
"I Wanna Go" is a 2011 song by Britney Spears. The song is the third single from her seventh studio album, "Femme Fatale". The song was released on June 13, 2011. It was an instant success, reaching the top ten of the "Billboard" Hot 100 a day after debuting. This resulted in a flash mob in Times Square. Spears also shut down Times Square for an unexpected performance.
The song has currently been downloaded over 1.8 million times in the US as of 2016.
The video premiered on June 22, 2011, and was directed by Chris Marrs Piliero. Spears is asked questions by paparazzi in a press conference and grows tired of them, eventually saying, "Fuck you" to all but one of them. She then goes for a joyride with actor Guillermo Diaz, known for his role in the television series "Weeds".

Jim Henson's Muppet Babies
Muppet Babies is an American children's animated series produced by The Jim Henson Company and Nick Jr. Productions, Kermit The Frog Productions and Marvel Productions which ran on Nickelodeon from 1984-1991, winning the Outstanding Animated Series Emmy for four consecutive years. The concept of presenting familiar Muppet characters as babies was introduced in a sequence of "The Muppets Take Manhattan". The movie featured puppet versions of Kermit the Frog, Miss Piggy, Gonzo, Fozzie Bear, Scooter, and Rowlf as babies (the puppet versions later returned one more time, for a home movie sequence in "A Muppet Family Christmas").
Cyclohexene
A cyclohexene is a six-sided (hexagonal) shaped hydrocarbon ring made when carbon atoms join with hydrogen atoms. It is flammable, toxic, and colourless liquid which does not dissolve in water. It will, however, dissolve in alcohol.
Mass spectrometry
Mass spectrometry (MS) is a process that measures the mass-to-charge ratio of charged particles.
You can use it to find out the mass of particles, and to find the basic chemicals in a sample or molecule. It can also tell you the chemical structures of molecules, such as peptides and other chemical compounds.
There are 5 main steps a mass spectrometer takes:
Using the information which the method can collect, you can find the "mass-to-charge ratio" of the particles, and the "relative abundance" (how many atoms of each type were in the sample you put in).
The first mass spectroscope was invented by the British physicist J. J. Thomson in 1912. His student Francis Aston developed the mass spectroscope for practical use. They are now widely used for agriculture, brewing, food processing, geology, petroleum exploration, medical drugs measurements and space exploration. They are often used with a chromatography system which helps prepare the sample for mass spectrometry.
Ashleigh Ball
Ashleigh Ball (born March 31, 1983 in Vancouver, British Columbia, Canada) is a Canadian voice actress and singer who is best known for voicing "Applejack" and "Rainbow Dash" in the television series and the character "Allura" in the television show Voltron Force. Ball is also the lead singer of the Vancouver-based indie pop/acoustic band Hey Ocean!.
She was the subject in the documentary "Brony: the Movie", which followed her through her first interactions with the Brony community at BronyCon 2012.
Ivan Kral
Ivan Kral (born Ivan Král; May 12, 1948 in Prague, Czechoslovakia – February 2, 2020) was a Czech-American guitarist, bass guitarist and songwriter. He has worked with Patti Smith and Iggy Pop. His songs recorded U2 and David Bowie.
Tornado warning
A tornado warning is an alert that means that a tornado or funnel cloud has been spotted around the area, and that people should take cover. When tornadoes have been spotted, the tornado sirens make sound in that place, letting people know that they have been seen.
Tornado warnings are higher than the warning of a Tornado watch, but there is an even "higher" level, which is a tornado emergency.
Tornado watch
A tornado watch is a warning that means that weather conditions are right for tornadoes to form. So people should be careful.
A tornado watch must not be confused with a tornado warning. It does not mean that a tornado has been seen; it just means that you should be careful because the weather is perfect for a tornado.
Dust devil
Dust devils are twirling masses of air that form in the desert and send sand spinning. The height of a dust devil can range from a few meters tall to more than tall. They are usually harmless, but occasionally they can cause some damage to both people and property.
A dust devil forms when hot air near the ground rises quickly through a small pocket of cooler, low-pressure air above it. If conditions are just right, then the air may begin to rotate. As the air rapidly rises, the hot air is stretched vertically and because of angular momentum, the spinning gets much more intense. Because the hot air cools when it rises, it eventually goes down to the base and expands horizontally, while more hot air shoots up the column to replace the lost air. The air that is displaced falls to the ground around the dust devil, creating a balancing force. Thus, a dust devil is formed.
