Wednesday and a relatively short blog post after two rather long posts in the preceding two days. The first topic concerns the limits to government spending. The second brief topic reports on research where it was found that the music of AC-DC confounds Lady Beetles and soybean aphids. Who would have thought! Which was by far the most interesting research paper I have read this week after dealing with the likes of Stuart Holland on Monday and Tuesday. And then some music from around the world to smooth out the day.
