Inspiring hope and contributing to a greater well-being of patients through creative teaching, integrated with our clinical practice, education and evidence based research. However, there are several things, such as heat, light and other forms of energy, that are not considered matter because they lack mass. It is neither a solid, liquid, or gas.
