We really love the ‘ask a physicist’ section where you can ask any question you want and get a real answer from an expert. You can also search through hundreds of scientific articles. The physics buzz section is fairly good but they don’t post daily which is shame. However, the ‘ask a physicist’ section makes up for the buzz (blog’s) lack of daily posts.
