I have found that when people are passionate about physics the predominant attitude they have towards other people's opinion of it is comparable to to how people view their religion (though maybe not as strong). They consider physics as the subject most worthy, or even the only subject worthy of pursuing. They want everyone to acknowledge physics as not only the most interesting subject there is but also the one which makes everything in modern society possible. One of my physics professors made this attitude very clear in his first lecture by saying he feels very dissappointed whenever he isn't able to convince someone else to like physics. I used to have this attitude also until maybe a year or so ago. Since then I lost the enthusiasm to spread physics and instead I developed what could be called a "possesive love" for it. This turned out to be a much more stressful attitude to have because when I hear of someone whom I dont consider worthy of being part of the "physics elite" I feel like an atom whose electrons suddenly fell to the lowest energy state, in other words I feel it diminishes my passion. This is how I felt when I found out about Angela Merkel and Brian May being physicists. When I knew that a guy who I didnt get on with was coming to university in the same year as me I worried a lot about him doing physics (it was likely as he is that kind of smart, quantitative person), and was greatly relieved when I saw that he wasnt. Now this year my sister seems to be enjoying physics and maths a lot in secondary school and it's getting me very worried. It's not that I greatly dislike her but I just dont see her as "worthy". I feel that if she also chose to do a physics degree I would like it a lot less. Now I really dont enjoy thinking in this way, so I was wondering did anybody else here ever have this attitude towards their field of study and how did they deal with it? Any advise for not classifying people into worthy and unworthy? Thanks in advance for all contributions.
