Brief History of Bayerische Motoren Werke:
BMW, a German company is a producer of automobiles and motorcycles. Designed as an aircraft manufacturer and originally founded in 1913 by Karl Fredrich Rapp, the company was commissioned to build the V-12 engine for Austria-Hungary. In need of extra financing, Rapp reconstructed the company as the Bayerische Motoren Werke. In 1917, Rapp left the company and it was taken over by Austrian Franz Josef Popp who later named it BMW. BMW continued their endeavors in producing for the German panzer (airplane) and the motorized division of the German airforce.
It was not until after the World War that BMW was banned from manufacturing for three years. In 1952, they began manufacturing automobiles. In 1959 BMW found themselves in a tough financial situation, as they almost had to sell their interests to Daimler-Benz, the number one auto producer as well as their number one competitor. However, with the opposition of the workforce and labor unions as well as an individual named Herbert Quandt, shares were increased by 50% and the company did a turn-a-round.
As recently as 2004, revenues for BMW were $44 billion dollars with an employee base of 105,972 (HBR 2004). Today, BMW accounts for 10% of the market share with 70% of their sales from Europe and 30% of sales from United States and Japan. These figures equate to the success of BMW and have helped them gain brand...

The first four partial sums of the Fourier series for a square wave
In mathematics, a Fourier series (English pronunciation: /ˈfɔərieɪ/) decomposes periodic functions or periodic signals into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials). The study of Fourier series is a branch of Fourier analysis.

Definition[edit]
In this section, s(x) denotes a function of the real variable x, and s is integrable on an interval [x0, x0 + P], for real numbers x0 and P. We will attempt to represent s in that interval as an infinite sum, or series, of harmonically related sinusoidal functions. Outside the interval, the series is periodic with period P. It follows that if s also has that property, the approximation is valid on the entire real line. The case P = 2π is prominently featured in the literature, presumably because it affords a minor simplification, but at the expense of generality.
For integers N > 0, the following summation is a periodic function with period P:
Using the identities:
Function s(x) (in red) is a sum of six sine functions of different...

...The Balmer series is characterized by the electron transitioning from n ¡Ý 3 to n = 2, where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-¦Á, 4 to 2 is H-¦Â, 5 to 2 is H-¦Ã, and 6 to 2 is H-¦Ä. As the spectral lines associated with this series are located in the visible part of the electromagnetic spectrum, these lines are historically referred to as H-alpha, H-beta, H-gamma and H-delta where H is the element hydrogen.
Balmer Series (Second) (visible light) n=2 limit = 365 nm
n = 3, ¦Ë = 656.3 nm, ¦Á, color emitted: red
n = 4, ¦Ë = 486.1 nm, ¦Â, color emitted: bluegreen
n = 5, ¦Ë = 434.1 nm, ¦Ã, color emitted: violet
n = 6, ¦Ë = 410.2 nm, ¦Ä, color emitted: violet
Although physicists were aware of atomic emissions before 1885, they lacked a tool to accurately predict where the spectral lines should appear. The Balmer equation predicts the four visible absorption/emission lines of hydrogen with high accuracy. Balmer's equation led physicists to find the Lyman, Paschen, and Brackett series which predicted other absorption/emission lines found outside the visible spectrum.
The familiar red H-alpha line of hydrogen which is the transition from the shell n=3 to the Balmer series shell n=2 is one of the conspicuous colors of the universe contributing a bright red line to the...

...Journey of Life to Heaven
“Uphill” by Christina Rossetti is about the journey of life, or death, to heaven. The poem is an exchange of a series of brief and succinct questions and answers between two speakers: an inquiring traveler who asks many questions about the journey of life or death in which she is heading to (heaven), and an ex-traveler or guide who has taken that path before answering with a assured, and perfectly calm tone. In the poem, the poet uses difference devices such as quatrain, common meter , and perhaps it is written in strict iambic meter with lines vary in length and in the number of feet. The poet uses imagery, and symbolism (allegory)to express emotion and picture a traveler who has to take the road “uphill”, and who hopes to find an inn at the end of her travel. The poem sends a message that though find life hard but there are always comfort, help, and generosity along the way.
This poem illustrates two ways in which line length is varied in a strict meter. The first variation is seen in the first line, which has nine syllables. This is still a five foot line because feet are constructed by iterative parenthesis insertion from right to left, the leftmost foot is the last constructed and can fall short.The second variation involves the number of feet in each line. As can be seen in “uphill” all odd-numbered lines are pentameters, whereas the even-numbered lines vary in length between three and five feet, there are 5 trimeter...

...History of the World Series - 1919
Unfortunately, Francis C. Richter was a little off the mark. The 1919 World Series was, in fact, not honorably played by every participant, as was disclosed late in the 1920 season when confessions were made.
Eight members of the 1919 White Sox -- pitchers Eddie Cicotte and Claude (Lefty) Williams, outfielders Joe Jackson and Happy Felsch, first baseman Chick Gandil, shortstop Swede Risberg, third baseman Buck Weaver and reserve infielder Fred McMullin -- were charged with conspiring to fix the outcome of the fall classic against the Cincinnati Reds. The eight became forever known as the "Black Sox."
A sharp shift in the betting odds shortly before the start of the World Series -- the highly favored White Sox suddenly became underdogs -- aroused curiosity, as did swirling rumors that something might be amiss in certain players' onfield effort. But, overall, fans and other observers accepted the "public presentation" of the 1919 Series. Perhaps, as apparently was the case with Richter, they saw only what they wanted to see.
What everyone saw in Game 1 was a scintillating performance by the Reds' Dutch Ruether. Whatever "assists" he might have received from various members of the opposition, Ruether pitched a complete-game six-hitter and went 3-for-3 at the plate (two triples) with three runs batted in. Outfielder Greasy Neale, who went on to lead the Reds in hitting in...

...Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid,and plan an investigation to test it out.The Metals given:Calcium,Aluminium,Iron,Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period,the element change from reactive metals on the left to non reactive metals on the right.On the extreme right of the periodic table is the noble gases.Also calcium is Group 2 which is the alkaline earth metals and they are part of the reactive metals which is Group 1 and 2.Also out of all of the metals given calcium reacts more faster with air and creates a sparkling sight and can damage your eyes creating calcium oxide in word equation it is Calcium+Oxygen equals calcium oxide.In chemical equation it is 4Ca +O2 equals 2 Ca2o.Calcium also reacts more than zinc,aluminum,iron and magnesium with water and much more violent and quicker creating vapour and moves much faster than the other metal and creates a vigrous sizzling sound and fizzing in water and dissloves much faster than the other metals. The alkaline metals get more reactive as you go down the group and calcium is further down than magnesium so therefore it must be more reactive than magnesium. Calcium is in group 2 in the periodic table...
