Re: What is the different between pseudoscience and science?

Science is the investigation of the natural world. It emphasizes careful 
measurement, development of theoretical systems, testing of theories against 
evidence, and replication of claims by other investigators.

Pseudoscience is the attempt to present unproven or unprovable claims in a 
"scientific" wrapping. Consider these sites as sources of inforamtion about 
pseudoscience:

You may want to investigate the areas of silicone breast implants, chronic 
Ebstein-Barr infections, chronic immune dysfunction, and chronic Lyme disease as 
medical examples where a lot of pseudoscience exists. Sometimes it is very hard 
to draw the dividing line. A historical inquiry into the diagnosis of 
neurasthenia would be interesting. It seems to have been relabelled in recent 
years. I'm sure if you follow up the areas listed above you will stumble across 
its new name.
