Latest research breakthroughs and innovations, science advances  and scientific discussion forum. We continuously update our contents to  provide worked physics problems and examples, organized by topic to provide  free physics related homework help to students.For students to develop the abilities that characterize science as inquiry,  they must actively participate in scientific investigations, and they  must actually use the cognitive and manipulative skills associated with  the formulation of scientific explanations. We hope worked physics problems  we provide in our site will help to easily understand the basic concepts  of solving physics problems. Also we have created dynamic physics tools,  which help you to find the answerer for many physics related problems. LivePhysics.Com offers a complete working tool for science teaching  and learning.LivePhysics.Com is all at once:A huge collection of online resources for students and teachersWe offer to science teachers and students a large collection of interactive  Flash™ animations, Flash™ dynamic tools to solve problems,  Java applet animations, interactive JavaScripts/ Ajax tools.A working tool for studentsEach animation comes together with scientific background behind the animation  and guidelines allowing the students to review the key functionality illustrated  by the animation.Latest Physics NewsNEWS25 OctBreakthrough for solar cell efficiencyScientists have just revealed the fundamental aspect of a new approach to growing InGaN crystals for diodes, which promises to move photovoltaic solar cell technology toward record-breaking efficiencies.25 OctNanoscale engineering boosts performance of quantum dot light emitting diodesDramatic advances in the field of quantum dot light emitting diodes could come from recent work. Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions.25 OctPhysicists observe the formation of a many-body system in experimentHow large does a group of particles have to be to render moot its exact number of particles? In experiments using ultracold atoms, physicists succeeded in observing the transition to a many-body system well described by an infinite number of particles. In philosophy, this problem is known as the sorites paradox. The essential question is when a collection of elements forms a "heap."25 OctPhysicists aim to make transition to quantum world visibleTheoretical physicists have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study
