Sidney Gottleib and the CIA

The gentle and intelligent expression you see on this man’s face runs completely counter to his actual deeds. This is Sidney Gottleib, one of the most powerful CIA officials in history, and he created a vast operation to develop mind-control experiments that involved torture and death — the casualty rates of which remain unknown.In the […]

Barry James Marshall and His Ulcers

It’s difficult to make a hero out of Edward Jenner, the doctor who developed one of the earliest types of vaccinations (for smallpox), but did so by experimenting on a nine-year old kid (James Phipps, the son of Jenner’s gardener). That kind of callousness fuels the fire of all sorts of negative stereotypes about scientists,

Walt Disney’s City of Tomorrow

Who could showcase the spirit of American trust in mid-20th-century corporate capitalism more than Walt Disney? His ambition and vision propelled him to wild success at a myriad of ventures in his lifetime. One of these great ideas failed to pan out however, and you see that portrayed here. These watercolor images are mock-ups by

Planet Nine

Planet Nine

We all know (some of us might still be sad about it) that Pluto was demoted to a “dwarf-planet” status back in 2006. In other news, however (and mayhaps this could make up for Pluto’s decline), some scientists have speculated that another planet — known as Planet Nine — might be orbiting our sun.Ideas about

Cleopatra the Alchemist

Cleopatra the Alchemist

This Ancient scientist was championed by intellectuals across time, and by the 1600s was known in Europe as one of the most important alchemists of Ancient history: Cleopatra “Chrysopoeia” the Alchemist (aka not the Pharaoh). Thought to have been active in the third century BCE, Cleopatra was praised in the early 1600s as being one

Otzi

Otzi “The Iceman”

Here’s a reconstruction of the oldest European mummy, called Ötzi, named for a region where he was found in the Alps back in 1991. His body had been preserved by his glacial environment for 5,300 years, and has been extensively studied by scientists who have put together a fascinating picture of the Iceman and his

Burdock in Shenandoah National Park

This is “Arctium lappa,” aka burdock. Originally from Eurasia, it is now an invasive species in North America — this beautiful specimen was flowering yesterday in the Shenandoah National Park, and July and August are typical months when the spiny bulbs blossom in lavender and purple. Although burdock root has long been used in cuisines

Earliest Sundials

The Earliest Timepieces from Ancient Egypt and the Hebrews

This Ancient Egyptian “shadow clock” dates to the Ptolemaic Period (330-306 BCE), but is representative of the earliest known timepieces. The earliest extant dates to about 1500 BCE, but this fragment is much more interesting to look at. Check out the parallel and oblique lines engraved on the sloping face: one would have placed a

William Ramesey’s Illustrations of Parasites

We who have been raised in a culture with microscopes and electronic microscopes take for granted the existence of a universe of minutiae that shape our surroundings (SARS-COV2, to pick an example we are all exhausted about). Before Antony van Leeuwenhoek developed his microscope around 1668, however, this was impossible.And so it was that a

view of the Duquesne Incline for railroads

Duquesne Incline

Pittsburgh’s unusual geography — with three rivers that conflate at different spots amidst steep hillsides — made it difficult for pedestrians to traverse. Starting in the 1870s, German immigrants started building funicular railcars to make getting around easier. Today only two of these remain, and the one featured here is the Duquesne Incline.   Built

Appearances of Homo Sapiens

I love how scientific technologies are helping us understand the earliest millennia of human history ever better. This drawing, for instance, features an artistic re-creation of skull fragments dated in 2017 that have helped to overturn our understanding of human evolution.   Basic questions, such as “how long have Homo Sapiens been around?” And “where

The Linear Astrolabe of al-Tusi

You are looking at an artist’s rendition of a device known as “the staff of al-Tusi” which sounds like a magical weapon straight out of Tolkien but in fact was a genius scientific tool made by one of the most important mathematicians in history.   Sharaf al-Din al-Muzaffar al-Tusi (c. 1135-1213) lived in various cities

Clovis Culture and Migration

When you were a kid, did you learn that the first humans in the Americas crossed over the Bering land bridge about 12,000 years ago? Scholars have overturned this chronology completely, but it held away for many years in part because of this type of spear- or knife- head technology featured here, which is the
