What Makes a Dune?

Wind and water can form sandy ripples in a matter of minutes. Most will be erased, but some can grow to meter-scale and beyond. What distinguishes these two fates? Researchers used a laser scanner to measure early dune growth in the Namib Desert to see. They found that the underlying surface played a big role in whether sand gathered or disappeared from a given spot. Surfaces like gravel, rock, or moistened sand were better for starting a dune than loose sand was. Each of these surface types affected how much sand the wind could carry off, as well as whether grains bounced or stuck where they landed. Every trapped sand grain made the surface a little rougher, increasing the chances of trapping the next sand grain. Over time, the gathering sand forms a bump that affects the wind flow nearby, further shaping the proto-dune. As long as the wind isn’t strong enough to scour the surface clean, it will keep gathering sand as the process continues. (Image credit: M. Gheidarlou; research credit: C. Rambert et al.; via Eos)

Small-scale sand ripples can form and disappear in a matter of hours.

husband), William A. Fowler & Fred Hoyle. The paper, one of the most-influential in #astronomy & nuclear #physics, reviewed everything then known about stellar nucleosynthesis, backed it up with astronomical & lab data & further explained how elements heavier than iron are made & the abundances of the various elements. Elements up to iron can be built up by nuclear fusion in stars & B2FH also explained how heavier elements are made. At the base of my print is a stellar absorption spectrum of

Sam Altman claims that science will be finished by AI in a few years. This is reminiscent of 20th century scientists who said similar things, but still, science is far from finished. I think the more we know about science, the more unanswered questions we will be left with.
