I had an interesting question raised to me last night that I didn't know the answer to...somebody asked me "since you have your civil PE license now, does that mean you could theoretically go get an electrical or mechanical engineering job and use your PE there? or does it only count towards civil engineering applications?" and i didn't know the answer...is the PE stamp valid for any type of engineering or just your discipline? the certificate/stamp doesn't specifically say which type of engineer you are, but i would think it would be unethical to be stamping plans pertaining to a subject in which i have very little knowledge.
