Languages in Flight

Saturday, January 21st, 2012

The most current research on language and language learning reveals, once again, that it’s much more complicated than anyone could have imagined.  There are those who have an unusual capacity, who seem to absorb words almost immediately.  A few days in a new Latin American country, and they are ready to begin a job in Spanish translation.  They are the anomalies.  In most cases, even with people who have a high capacity for learning new languages, it takes time and energy.

 

The bad news is that there isn’t a secret lock in the brain that will open the capacity for language the way it works for those rare types.  It is a cognitive science, and athough the structures of languages might be within intuitive reach, a massive vocabulary is not.  It’s not likely to learn a language on the plane between one place and the next.  But practice and repetition do work, and any time is a good time to begin, even if that happens to be on the airplane.  A little familiarity with the grammar, and a decent Spanish dictionary, and one can do an awful lot in a new place.  This is provided that they don’t stray too far off the beaten path.  For those who do want to see new places and meet new people, but not in the way that it’s meant to be experienced for tourists, then some more intensive work is absolutely necessary.

 

At least for the time being.  The studies in cognitive processes do keep revealing that the brain is a complicated and endlessly baffling instrument, and the more that scientists know, the more unknowable it all seems.

 

It’s very unlikely that anyone could be genetically programmed with that secret gift for picking up languages instantly, but the brain does seem to know more than one might think.  A great deal of work on the way word order processing works in learning another tongue reveals that there are rational and intuitive things going on simultaneously.  From a very early age, it seems, and perhaps even in the womb, the brain chemistry changes slightly when in a situation where the native language is not being spoken.  Also, and even more compelling perhaps, is that the brain seems to be able to grasp how the language is structured very quickly.  So even if it doesn’t know the words, it can recognize that the subject and objects, and the verbs and modifiers, fall into a certain pattern.  Maybe another generation might have enormous benefits from what linguistics is teaching now, but until then, poring over a phrase book in mid-flight is a very good idea.

 

Tungsten Carbide Has Many Uses

Monday, May 30th, 2011

With a melting point of 5200 degrees Fahrenheit, tungsten carbide is an extremely durable metal and is pretty much indestructible. It takes a temperature of over 10,000 degrees Fahrenheit to make the substance boil. Because it is a composite of tungsten and carbide, it can be made at different grades, depending on how much of each element is present and how high a temperature was used to create the metal.

Each grade of tungsten carbide is designed for specific uses. Its durability and resistance to heat, cracking, and scratching makes it ideal for many military applications. It is also a common material in the production of tools, especially those instruments used for cutting.

Common household items may be made of tungsten carbide. As in the case of tools, blades are a popular household application of the metal. This includes items like razor blades and kitchen knives. It can also be found in many ballpoint pens.

There has been a recent increase in demand for tungsten carbide rings , especially engagement and wedding rings. The durability of a ring that is ten times stronger than gold is an important symbol of the endurance of marriage while also being a practical consideration. Rings are meant to last a lifetime and tungsten carbide is going to resist dents, scratches and wear much longer than other metals. It is also available in a variety of beautiful finishes and composites that make it visually attractive.
