Hello everybody, this is my first post here (or anywhere for that matter)
This is slightly off topic but i may be able to clear up one query in this thread. The instiute of physics is a UK based organisation that promotes physics education and research to other scientists and the public. Membership of the institute of physics has several grades. The affilate grade is open to anyone with an interest in physics, other grades require proof of a physics qualification. For example i was a graduate member of the institute as i graduated with an astrophysics degree, i had a chartered physicist to act as a supporter and sent off my cheque for membership. Membership of this organisation does back up your credentials but does not mean you are an expert in all areas of physics.
