In the 18th and 19th centuries scientists wrestled with identifying and describing the nature of the “stuff” that produced change. One concept that became popular for a while was that of “caloric” (what we now call heat). “Caloric was originally conceived of as a quantity that would flow from a hotter object to a cooler one that would warm up as a result. It answered the need for a way for the cause of warming to get from here to there. Not only did caloric serve as a cause for warming‚ it

Hot Weather Risks As the summers are approaching and the tempratures have started to rise‚so it will have its effects on our bodies.In order to perform our duties safely and efficiently we need to understand this change in weather and acknowledge the effects and risks associated with it. Because if we are mindful of the fact that our bodies need to adapt with this change only then we shall be able to do requisite measures to counter it. I will not be discussing the risks associated to ground/air
