Around the world there are several languages but few of them are essential to achieve a great life like English, German, French, Chinese, Spain, etc. if you master at least two of them you have a high probability to accomplish a good job and of course get to know about other customs and culture, so the pursuit of this post is to spread like wildfire that you can learn German totally free and come to mind that obviously taking a course is better because you are guided by a teacher and you can share your doubts immediately.

On the other hand many resources for self learners are available on the internet such as podcast, blogs, online courses, forums, facebook, etc. Thus, as a German learner I wish to share some practical tools which are free, the only thing you must do is download and try out!.

Firstly, iTunes provide plenty of podcasts trough its Online Store but how can I get it? well... type on the search box "learn German" and many podcast about this issue will be displayed an the next step is to download.

Second, I think this is the a GREAT!!!!! tool ever made for begginer learners according to the Common European Framework of Reference for Languages, I am talking about "Deutsch Interaktiv" offered by Deutsch Welle, it's a fantastic course for level A1.1 until B1.1, the main goal is provide a solid background on the daily German language throughout many activities. Once you have started the limit is set by self.

Finally, the Institute Goethe offers an online course together with Tell me more!, there are two kind of course, the L course for normal learners and the XL course for fast students. Actually, I am taking the second one and let me know you is a great course due to students work in depth phonetics, grammar, lexical and cojugation points encountered in the course.

I look forward hearing your opinions and contributions to Study German or any Language in a free way.

Esta información es relevante para quienes son estudiantes de los últimos semestres de las escuelas pertenecientes o afiliadas al Instituto Politécnico Nacional (IPN) debido a que uno de los documentos que nos solicitan para llevar a cabo la titulación es la liberación del servicio social. Es importante conocer el plazo máximo al que están obligados las autoridades del IPN para proporcionar la constancia de liberación del servicio social porque como egresado de la Escuela Superior de Ingeniería Mecánica Eléctrica (ESIME) campus Zacatenco es el trámite angular de la nueva titulación curricular debido al perido que tenemos para llevar a cabo esta modalidad de titulación que es de un año. Por lo general la oficina de Servicio Social tarda aproximadamente de 4 a 6 meses en entregar el susodicho documento y por consecuencia retrasa el trámite del acta de titulación.

Hace poco recibí un e-amil en el cuál exponian el plazo máximo de entrega y quede estupefacto porque solamente es de 30 dias hábiles!!!!
Esta información la pueden corroborar en la página de obligaciones de trasnparencia del IPN www.transparencia.ipn.mx o al siguiente link http://www.transparencia.ipn.mx/servicios/AreasCentrales/SriaExtencionDifusion/1T04serviciosDirServicioSoc.pdf.

A continuación anexo parte del e-amil, la verdad no he corroborado la veracidad del siguiente tip pero para aquellos que esten deseperados por acelerar el trámite de la constancia de liberación es una buena alternativa y ojalá funcione porque el que no protesta no es escuchado.

IMPORTANTE!!!

Este tìp es vàlido para cualquier escuela del POLI ya que los funcionarios que enuncio en las siguientes lineas son encargados de las liberaciones de todas las escuelas del POLI...

Para agilizar tu tràmite, debes ir PERSONALMENTE (por que sòlo asì te hacen caso) con el Dr. Omar Hernàndez Montes quien es el Jefe de la divisiòn de Servicio Social. El se encuantra en Av.

Urban Myth

Surfing on the internet, it can be found a lot of interesting facts, one of them is "A duck's quack doesn't echo". The premise is dubious because many sounds produce echo and why precisely a duck's quack. Fortunately in spring 2003 the urban myth fall down, Salford Acoustics was the source of the story being presented in the national and international media that revealed the

Concepts

Echo - The reflecting sound off a wall or inside a confined space so that a noise appears to be repeated.
Duck's quack - Each breed of duck generate particular sound and even the same breed is different male's quack from female's quack, then around the world exist plenty of quacks and how can't produce an echo?

Research

The centre of the acoustic research at the University of Salford in Manchester took place the research the popular urban myth. Daisy was the main character on the experiments because the research team use her quack. The first recording took place in anechoic chamber where Daisy's quack scatter without wave reflections in order to show what happen

The next step was to record at reverberation chamber with cathedral-like acoustics. The room is used to measure properties of building products.

Now, it's possible to simulate an open area such as cliff side where duck flying. By means of electronic box produced the sound expected.

Results

Both recording sounds can be clearly heard when an echo occurs. Consequently, a duck's quack does echo but it might be hard to hear. The tests revealed that a duck's quack definitely echoes, but the power sound is too low for human ears.
