United States Students Lag in Math and Science United States high school seniors scored near or at the bottom of a multinational study of student performance in science and mathematics, according to results released on February 24, 1998. Final results from the Third International Mathematics and Science Study (TIMSS), said to be the most comprehensive ever, also showed that U.S. students' aptitude for mathematics and science declines as they get older. Conducted in 1995, TIMSS tested student abilities

real analogy in the everyday world. The quantum theory that describes the behavior of electrons is a cornerstone in modern chemistry. Quantum theory can be used to explain why atoms are stable, why things have the color they do, why the periodic table has the structure it does, why chemical bonds form, and why different elements combine in different ratios with each other. Light and electrons both behave quantum mechanically. To understand the experimental basis for the quantum theory, we have to begin

Global pandemic: Of the Purple Cocci March 1st 2014 Abstract Hard to believe that a very common bacterium that is nearly present on everyone’s skin has been the cause of thousands of deaths every year. It has gained virulence that helps it survive a host’s immune system and many common antibiotics. This bacterium produces biofilms and toxins which allows it to survive in a host’s body. This bacterium has increasingly new strains that have evolved genetically. With new genetic strains it because

elevate the quality of our life altogether? We know that chakras are energy centers that are spinning like a wheel. They move energy around as they spin and bring life force into every part of us. We have many chakras, each cell and every molecule is a chakra and each atom and every particle is a chakra. When chakras move in a synchronized manner with each other, energy flows freely and we experience a sense of centeredness and confidence. However, when some chakras
