Welcome to acoustic science

This blog has been created with the objective to improve my English. This is part of the activities of my English 4th course. I would like that readers enjoy reading this blog so I have been thinking about it and I finally decide to write about the science in our lives, historical facts and other things…. For example, the first time that the clock was set forward one hour in summer and delayed in winter was in the First World War. Then there was a period when there were not any changes. However the change returns with the petroleum crisis in 1973 since now in order to take advantage of the sun light and to save energy. I explain this because tonight we have to change the clock, don’t forget it!!!
