When I use words such as "prove", "proof", "certain", etc. I am using the meanings/definitions as described in the public dictionaries. I tend not to use personal private meanings which some deluded individuals use who think that you can't prove anything in science.
Oh Ted, you are a blast, but you're still wrong.
Here are two features of a proof, neither of these features exist in science:
1) A proof is final, a valid proof cannot be changed.
2) A proof is binary.
Your appeal to dictionary definitions is hilarious. Dictionaries are descriptive and not prescriptive.
Once again, you have shown your naivety in all matters related to logic, philosophy and science.
