Ripple reflections on Bull Creek cliff

Not having been to the main section of St. Edward's Park for a long time, I went there on the morning of June 24th. At one of the access points to Bull Creek I noticed that sunlight was reflecting off ripples in the creek and creating shimmers on the cliff. Those shimmers of light in turn appeared upside down as they reflected off the surface of the water on their way to my eyes and to the camera that I put between my eyes and them.

Southern maidenhair ferns (Adiantum capillus-veneris) created the horizontal green band of foliage across the cliff just above the water level. Starkly uneven lighting (which I could only partly even out while processing the image) produced a strange effect: the ferns in the right half of the photograph are clearly reflected in the water, while the main group of ferns in the left half doesn't have an obvious reflection.

One of the most important developments in the study of racial inequality has been the quantification of the importance of pre-market skills in explaining differences in labor market outcomes between Black and white workers. In 2010, using nationally representative data on thousands of individuals in their 40s, I estimated that Black men earn 39.4% less than white men and Black women earn 13.1% less than white women. Yet, accounting for one variable—educational achievement in their teenage years—reduced that difference to 10.9% (a 72% reduction) for men and revealed that Black women earn 12.7 percent more than white women, on average. Derek Neal, an economist at the University of Chicago, and William Johnson were among the first to make this point in 1996: "While our results do provide some evidence for current labor market discrimination, skills gaps play such a large role that we believe future research should focus on the obstacles Black children face in acquiring productive skill."

That's from Roland Fryer's June 2022 article in Fortune magazine entitled "It's time for data-first diversity, equity, and inclusion." That passage supports what I've been saying for decades: the single most important thing our society can do for underprivileged children is give them a good education. Instead, the people in charge of education keep making excuses and adopting policies which practically guarantee that those children won't learn much. It's a disgrace.
