Warren Buffett được biết đến như một trong những nhà đầu tư chứng khoán thành công và có ảnh hưởng nhất trong lịch sử. Cách tiếp cận đầu tư của ông gần như không thể cho các nhà đầu tư cá nhân nhân đôi vì ông sử dụng đòn bẩy và cách tiếp cận dài hạn mà hầu hết mọi người thiếu ý chí và sự giàu có để tuân theo.[9]

HF spoler og transformatorer. Den nederste transformator er en kombineret langbølge- og mellembølge-transformator som bliver koblet som svingningskreds. Den fungerer også som antenne, da den kobler til LB og MB elektromagnetiske signaler via magnetisk kobling fordi ferritstaven ikke er lukket i en sluttet kurve.
English: Ferrite rod antenna loopstick (bottom) and RF chokes, coils and IF transformers (top) used in radio equipment. The ferrite antenna has two windings, to receive both the LW and MW bands. The loopstick and chokes at top right are wound with litz wire in a basket weave pattern, with adjacent winding layers at different angles, to reduce resistance due to proximity effect and skin effect.

A Royal Canadian Air Force (RCAF) CF-18 Hornet, 4-Wing, takes off from Cold Lake, Alberta, Canada during the second Tiger Meet of the Americas. The Hornet is carrying two types of Air Combat Maneuvering Instrumentation (ACMI) pods on the wing tips. The Tiger Meet of the Americas, first ever held in Canada, inaugurated in 2001 in the Western Hemisphere to carry on the Tiger tradition of the long-established European original experience; promoting solidarity and operational understanding between NATO members. The Meet attracted 400 participants and over 20 aircraft, with at least 6 fighter jets painted in distinctive "Tiger" schemes. For a squadron to be invited, only one simple criterion required, the unit must have a Tiger or other big cat on their unit's insignia or as a mascot.Location: 4 WING-COLD LAKE, ALBERTA (AB) CANADA (CAN)

Mentre la logica classica partiva da un punto A del tutto a priori rispetto all'esito del ragionamento (B), nella dialettica hegeliana il flusso logico che va da A a B, dove questo antiteticamente contraddice ma non annulla (aufheben), spinge ad arricchire la tesi iniziale in una sintesi onnicomprensiva (C).[36]

Imagine care a apărut pentru prima oară în ziarul nazist Völkischer Beobachter, înfățișând în mod ostentativ o germană din Sudeți din localitatea Asch plângând de bucurie în momentul în care Hitler a traversat în 1938 fosta frontieră ceho-germană. Propaganda aliată a folosit aceeași imagine în propriile scopuri.
For documentary purposes the German Federal Archive often retained the original image captions, which may be erroneous, biased, obsolete or politically extreme. Note: This description has been identified as biased or incorrect: Socialist propaganda.  Eger, beim Einrücken deutscher Truppen ADN-ZB-Archiv Nazi-Gruß in Cheb (Eger) Mit erhobenem Arm, dem Hitler-Gruß, stand diese Frau an der Straße, als die Truppen des faschistischen Deutschlands nach dem Münchner Abkommen (29./30.9.38) in diese Stadt einrückten. Dieser Gruß war nicht überzeugend, er war erzwungen. Diese Frau drückt es in ihren Tränen aus.- Tränen der Not, der Entbehrung und menschliches Leid. Was hat sie durch die Faschisten erleben müssen, was steht ihr nach diesem Tag noch bevor? [Besetzung des Sudetenlandes, Oktober 1938] Information added by Wikimedia users.English: This iconic picture of the Anschluss of the Sudetenland has been captioned and interpreted differently, depending on who published it. The Nazis, who first published it in autumn 1938 shortly after the Anschluss in their newspaper Völkischer Beobachter, claimed the woman cried tears of joy. See for instance this history of the Sudetenland, which seems to use such a caption: A Sudeten woman, overcome with emotion, pays homage as the Wehrmacht enters the Sudeten border town of Cheb. Also see the letter Lieutenant Earle A. Cleveland wrote to the Time Magazine (printed November 12, 1945). He wrote: The Nazi explanation was that here were portrayed the intense emotions of joy which swept the Sudeten Germans as Hitler crossed the Czech border at Asch and drove through the streets of the nearby ancient city of Eger, 99% of whose inhabitants were ardently pro-Nazi Sudeten Germans at the time... to which the Time editors commented ...sauce for the Nazi goose is sometimes sauce for Allied propaganda. The U.S. National Archives and Records Administration (NARA) provides this image (as #78) with the caption The tragedy of this Sudeten woman, unable to conceal her misery as she dutifully salutes the triumphant Hitler, is the tragedy of the silent millions who have been 'won over' to Hitlerism by the 'everlasting use' of ruthless force. which is similar in spirit to the ADN/Zentralbild (a GDR news agency) German caption preserved by the German Federal Archive. Translation: With her arm raised to the Hitler salute, this woman stood at the roadside when the troops of fascist Germany entered this town [Cheb] after the Munich Agreement (Sep. 29/30, 1938). The salute was not convincing; it was forced. She expresses it in her tears. Tears of misery, of deprivation, of human suffering. What has she gone through because of the fascists; what will she experience after this day?
