New Dye was Adopted Quickly in the 18th Century

Despite this being a "scientific"age, not everything is known about the technology of the past.  New research shows that adoption of new things was quite rapid in the 19th century  For example, a dye was being used industrially only four years after its invention.
Methyl violet dye used to make a 19th century dress
Examination of purple threads from dresses by molecular spectroscopy shows that shows that it was widely used by consumers. Before synthetic dyes were developed only royalty could afford purple dresses as existing dyes were made from molluscs.

After analysis using thin layer chromatography, energy dispersive x-ray and enhanced Raman spectroscopy a dye was identified in three dresses as being methyl violet. It was invented in 1861 and in shops by 1865, Even today getting a new product to market is usually only done with computer related merchandise.

Albert Einstein's Genius Was Due to His Unusual Brain

Albert Einstein wasn't only a genius her was a very odd human being. His brain shows peculiar differences from the norm; it had many more folds than the average person. This gave the brain a greater surface area. It is like using a larger computer to do calculations. Upon his father's death in 1955, Thomas Einstein gave the pathologist permission to preserve the brain of Albert Einstein. It was photographed then dissected into 2,000 ultra-thin slices. The slices and slides of them were later distributed to researchers. The brain had more neurons and glia cells, well outside of the normal range; pariental lobes were unusual in the pattern of ridges and grooves. Einstein only had a brain of average size. The area controlling the tongue and face was larger, as was the region that involves attention and planning. Overall, Einstein's brain was complex. Many people think in words. He said his thinking was like a physical activity. If selection based on "healthy...

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...
