You would think in this day and age, there would be a lot less people attending college now that subjects taught in college are not restricted only to college classrooms any more, but instead college attendance has increased dramatically in the past 50 years. In the early 20th century, only 3 percent of the population went to college. Now 25 percent of the population attends college. I know you won't be able to get a job in physics without an advance graduate degree in physics. However, it is possible to perform physics experiments in this day and age where the latest scientific research papers are available on demand to everybody and not only available to the physics community and where different versions of lectures on physics , from introductory physics to general relativity popped up on the web everyday, and there is ample software available like matlab,mathematica, and maple to model your experiments. You can easily communicate your scientific ideas to members of the physics community via the web. People at the LHC give lectures and seminars on the experiments at LHC /.Hey, If Einstein was able to developed his ideas for Special Relativity in a swiss patent office and Issac Newton was able to developed his ideas on motion and gravitation on his Uncle's farm, why a mere mortal who doesn't possess Einstein's and Newton's genius who resides in the information age can't developed there own ideas related to physics. ? autodidacticism should be promoted more and encouraging kids to attend college should not be promoted as much, especially since most college graduates never used there degree in the field they decide to have for a career. You save lots of money by simply looking at the information provided by some universities and other individuals online, why s attend college and drown in thousands of dollars worth of debt once you obtained your degree when every subject taught in college is also available outside the ivory towers of college? Colleges today are not like Plato(or was it Aristotle ) academy where discussion of ideas between students and professors were often promoted more than given students grades , tests, homework, etc. In fact, I don't even think plato's academy gave out grades to students back then. Students and the teachers would meet together in a group and have discussions on there topics of interests.
