Learn About Wine Legs or Tears

What does it mean when a wine is said to have legs or someone refers to tears of wine? Wine legs or tears of wine are the droplets that form in a ring on the glass above the surface of a glass of wine or other alcoholic beverage. The drops continuously form and fall in rivulets back into the liquid. You can see the effect in the shadow of this glass of wine. Cause of Wine Legs While some people think wine legs are related to the quality, sweetness or viscosity of wine, they are really indicative of the alcoholic content of the wine and are caused by the interplay between adhesion, evaporation and surface tension of water and alcohol. How Wine Legs Work Capillary action draws a small amount of wine up the surface of the wine glass above the liquid. Both alcohol and water evaporate, but the alcohol has a higher vapor pressure and evaporates faster, producing a region of liquid that has a lower concentration of alcohol than the rest of the wine.  Alcohol has a lower surface tension than water, so lowering the concentration of alcohol raises the surface tension of the liquid. The water molecules are cohesive and stick together, forming droplets that eventually become heavy enough to fall back down the glass in streams into the wine. History of the Explanation of Wine Legs The effect is called the Marangoni or Gibbs-Marangoni Effect, in reference to Carlo Marangonis investigations into the effect in the 1870s. However, James Thomson explained the phenomenon in his 1855 paper, On certain curious Motions observable at the Surfaces of Wine and other Alcoholic Liquors. Test It Yourself The Marangoni effect more generally refers to the flow of liquid caused by surface tension gradients. You can see this effect if you spread a thin film of water over a smooth surface and add a drop of alcohol to the center of the film. The liquid will move away from the alcohol drop. Swirl a glass of wine or liquor and observe the wine legs or tears of wine on the glass. If you cover the glass and swirl it, wine legs eventually will stop forming because the alcohol will be unable to evaporate.

Professional Development And Education Development Essay Example For Students

Professional Development And Education Development Essay IntroductionProfessional development, in its most simple definition, is learning opportunities. Under professional development, individuals are open to a wide array of these opportunities in order to gain knowledge and improve. The learning opportunities that make up professional development take up many forms. Conferences that aim to teach new skills and methods, formal pieces of academic material, training methods provided by an external or internal organizations are all learning opportunities through which professional development is attained. Professional development is a continuous process, that requires adapting to new techniques and approaches to improve a person’s technical capabilities. The National Staff Development Council (2009) shed more light on professional development in education. The definition put out by the NSDC (2015) in a proposed modification to the elementary and secondary education act, states that professional development is â€Å"a comprehensive, sustained and intensive approach to improving teachers’ and principals’ effectiveness in raising student achievement† (Gilbert, 2009).Professional Development and Education Education is the bedrock of building a well functioning society. It provides the fundamental and advanced knowledge needed to improve the well-being of a country. Education is critical to the development of a country’s youth, as the popular saying goes, children are the future. The education received from teachers can either leave a lasting impact or have little or no effect on understanding. The Woodrow Wilson National Fellowship Foundation asserted that there is a need for â€Å"new paradigms, new practices and new people† (as cited in Holaday et al, 2007, 99).

The manner in which students have been taught in the past, stifled any form of creative energy and freedom. The information that was passed on was abstract and only needed to be understood enough for the purpose of graded exams. However, an understanding of material, brought about by teachers’ taught to cater to the distinct needs of their pupils, demonstrates the enormous benefits of professional development. Whilst the need for professional development is clear, it is often unrecognized by the authorities that can implement such strategies, especially in education. Professional development is a tool that should be used more widely. Its use in education shows the benefits of such programs and show that it can be applied in fields where management and leadership are required.
