Puzzle (2010 film)

Puzzle (Spanish: Rompecabezas) is a 2010 Argentine drama film directed by Natalia Smirnoff. It was nominated for the Golden Bear at the 60th Berlin International Film Festival.

Plot

A middle-aged housewife, Maria del Carmen (Maria Onetto), suddenly finds she has a gift for assembling puzzles. Unbeknownst to her husband (Gabriel Goity) and two college-age sons, she begins practicing for a tournament with a man (Arturo Goetz) she met through an ad in a puzzle shop. The thrill "of a woman discovering her special gift and rejoicing in it" is just one of the surprises in store for Maria, as she starts to look differently at the pieces of her life, and to try new things.

Reception

Critical reception to the film was mostly positive, according to reviews cited at IMDb, with the notable exception of V.A. Musetto in the New York Post who said, "If the plot of the Argentine soaper Puzzle seems familiar, that's because it's nearly identical to the story in the French movie Queen To Play." Comparing this film to Lucrecia Martel's The Headless Woman, in which Maria Onetto starred in 2008, Stephen Holden of The New York Times said, "Although Puzzle is a much smaller, less ambitious film without the ominous political subtext of Ms. Martel's masterwork, its story...has implications about sexual inequality in Argentina's middle class." Holden also notes that Smirnoff served as Martel's casting director on the 2008 film. The A.V. Club says, "its conclusion is pleasing and not at all pat, a portrait of a woman who's learned she deserves to keep some things for herself."

Puzzle (1974 film)

L’uomo senza memoria (internationally released as Puzzle and Man Without a Memory) is a 1974 Italian giallo film directed by Duccio Tessari. It was written by Ernesto Gastaldi. La Stampa defined the film as "full of ideas and with a strong storyline".

Euler–Lagrange equation

In calculus of variations, the Euler–Lagrange equation, Euler's equation, or Lagrange's equation (although the latter name is ambiguous—see disambiguation page), is a second-order partial differential equation whose solutions are the functions for which a given functional is stationary. It was developed by Swiss-Russian mathematician Leonhard Euler and French-Italian mathematician Joseph-Louis Lagrange in the 1750s.

Because a differentiable functional is stationary at its local maxima and minima, the Euler–Lagrange equation is useful for solving optimization problems in which, given some functional, one seeks the function minimizing (or maximizing) it. This is analogous to Fermat's theorem in calculus, stating that at any point where a differentiable function attains a local extremum, its derivative is zero.

In Lagrangian mechanics, because of Hamilton's principle of stationary action, the evolution of a physical system is described by the solutions to the Euler–Lagrange equation for the action of the system. In classical mechanics, it is equivalent to Newton's laws of motion, but it has the advantage that it takes the same form in any system of generalized coordinates, and it is better suited to generalizations. In classical field theory there is an analogous equation to calculate the dynamics of a field.

EL34

The EL34 is a thermionic valve or vacuum tube of the power pentode type. It has an international octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. The American RETMA tube designation number for this tube is 6CA7. The Russian analog is 6P27S (Cyrillic: 6П27C).

Specifications

In common with all 'E' prefix tubes, using the Mullard-Philips tube designation, the EL34 has a heater voltage of 6.3V. According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with 800V plate voltage can produce 90 watts output in class AB1 in push–pull configuration. However, this configuration is rarely found. One application of this type was in "Australian Sound" public address amplifiers commonly used in government schools in Australia in the 1950s, using four EL34s for ~200 watts. More commonly found is a pair of EL34s running class AB1 in push–pull around 375–450V plate voltage and producing 50 watts output (if fixed bias is used), while a quad of EL34s running class AB1 in push–pull typically run anywhere from 425 to 500V plate voltage and produces 100 watts output. This configuration is typically found in guitar amplifiers.
