I am an EMT. I have joined this forum primarily because I have a question about pressure and volume when administering oxygen that I have already posted. That said, I do enjoy physics. I started an engineering degree in 2008 and have since switched over to medicine. Physics was always very interesting to me, but I have struggled with it. I have been better at math than physics. I greatly appreciate learning environments like this one and hope to understand new concepts by participating in this forum. Thanks to everyone who contributes to this important and valuable resource.
