Two classes ago Mr.Calvert taught us a about some type Greek guy who found out about Amber, I thought that it was really cool because when you rubbed the wool on the pvc pipe, you can attract paper with it, it turn out that the negative forces and the positive attract each other and two of the same kind repel each other, I thought this was like you and your best friend and your worst enemy. Like you always stick with your best friend and always away from your enemy. Also, I found it quite surprising that we found out about this more than 2000 years ago, this just shows that how smart we humans really are. It also, shows how lucky we are to have all these inventors who make life easier for us, for example, Thomas Edison’s light bulb would you imagine how much we would not have!
