reconstructed skull of ardipethicus ramidus

Ardipithecus ramidus

In the US, Mother’s Day is this Sunday, so I thought it appropriate to introduce this fine specimen, representative of what many Paleo-anthropologists consider the earliest known mother of all hominids (including us Homo sapiens). This is the Ardipithecus ramidus, and she lived about 4.4 million years ago in what is now modern Ethiopia. Her […]

design from medieval manuscript depicting the positions of the earth, moon, and sun during the solar eclipse

The Solar Eclipse

Yesterday, I was fortunate to experience the full solar eclipse from the Pymatuning State Park Reservoir in western Pennsylvania. The light turned silvery as the sun neared total obfuscation, and green colors emerged and reds dimmed, the effect of our eyes’ cones coming offline and employing the rods more. Shadows close to the ground sharpened

Voynich Manuscript

The Voynich Manuscript

Finding a more arcane and mysterious text than the Voynich Manuscript would be difficult. Written in 1420, the script has thwarted the world’s best cryptogrographers – linguists have failed alongside computer A.I specialists to decode the 200-page book. Just yesterday a story broke that a British linguist has solved the code – he claims the

Trofim Lysenko

Trofim Lysenko

Trofim Lysenko, the Stalinist-era biologist who tailored his scientific ideas to suit the Soviet communist party. Denying natural selection and arguing that character traits developed in a parent’s lifetime could be passed onto offspring (like Lamarck), Lysenko put the study of biology in the Soviet Union back by decades. Many actual scientists he competed against

Eclipses and the Theory of Relativity

This picture of the solar eclipse of May 29, 1919, is not only beautiful but also scientifically important. It was taken by British scientist Arthur Eddington (1882-1944), and was the first physical test of Albert Einstein’s General Theory of Relativity. Of course, in retrospect, over 100 years later it might seem obvious that massive objects

Chamberlain-Kahn Act of 1918

This is a photo from 1943 of a detention hospital for infected women in Leesville, Louisiana. And I’m about to deliver a really sad story about the U.S. government’s treatment of women during the 20th century. This is about a series of laws that came to be known as “The American Plan,” and they resulted

Lechuguilla Cave

The Lechuguilla Cave in south-eastern New Mexico (you can see a photo of part of it in the first slide) is the second deepest in the US (at 1,604 feet), and it runs underground for 150 miles. Located in the Carlsbad Caverns National Park, the cave isn’t open to regular visitors because it includes an

Yersinia Pestis

Yersinia Pestis

This baddie not only flourished in 14th and 15th century Eurasia. It also killed millions in the 6th cenuury, and struck again in 19th century China. Scientists are now thinking it might have caused a bottleneck in the population of Europeans in the Neolithic era too!
