A Flammarion wood engraving by an unknown artist that first appeared in Camille Flammarion's L'atmosphere: meteorologie populaire (1888). The image depicts a man crawling under the edge of the sky, depicted as if it were a solid hemisphere, to look at the mysterious Empyrean beyond. The original caption translates to "A medieval missionary tells that he has found the point where heaven and Earth meet..."

Color-enhanced Scanning Electron Micrograph (SEM) of the surface of a marijuana (Cannabis sativa) plant, showing glandular cells called trichomes. These are capitate trichomes that have stalks. They secrete a resin containing tetrahydrocannabinol (THC), the active component of cannabis when used as a drug. Magnification: 35X when printed 10 cm wide.

This image is a composite of different SEM images of cells from the immune system to illustrate a cytokine storm. The small cells are different types of leukocytes; the large ones are macrophages. During a normal immune system reaction, the immune cells produce cytokines that attract other cells, which also release cytokines. In a cytokine storm (also called hypercytokinemia), the immune system releases very high concentrations of cytokines.

December 7th, 1968.This image of a proton-photon collision was obtained with a bubble chamber at the Stanford Linear Accelerator Center (SLAC), showing the collision between an hydrogen nucleus (proton) and a high-energy photon. The collision has taken place in the area at center right; the track of the photon is not visible because only charged particles leave tracks in a bubble chamber. Nine particles (in red) are seen branching from the collision site heading towards the bottom of the image. The tight spirals scattered in the frame are electrons whose trajectories are strongly curved by the magnetic field of the bubble chamber. The high-energy photon was produced by allowing SLAC's 2-mile electron beam to strike a target, releasing th...

Nat Turner (October 2, 1800 - November 11, 1831) was an enslaved preacher who led a rebellion in Southampton County, Virginia, beginning August 21, 1831. Rebel slaves killed from 55 to 65 people, at least 51 being white. The rebellion was put down within a few days, but Turner survived in hiding for more than two months afterwards. When found, he was tried, convicted, sentenced to death, hanged and possibly beheaded

Weaponry used by the Knights Templar. Catapult (extreme left), battle-axe (center right), mace (above battle-axe) longbow (top right) and many of the knights are seen brandishing the broadsword. Officially endorsed by the Catholic Church (1129), the Knights Templar became a favored charity throughout Christendom, and grew rapidly in membership and power. In their distinctive white mantles with a red cross, they were among the most skilled fighting units of the Crusades.

Harriet Tubman, seated in chair, facing at her home in Auburn, New York. Harriet Tubman (1822 - March 10, 1913) was an American abolitionist and political activist. Born a slave she escaped to Philadelphia, then returned to Maryland to rescue her family. Using the Underground Railroad she rescued about 70 people, family and friends. Tubman met the abolitionist John Brown in 1858, and helped him plan and recruit supporters for the raid on Harpers Ferry. When the Civil War began, Tubman worked for the Union Army, first as a cook and nurse, and then as an armed scout and spy. The first woman to lead an armed expedition in the war, she guided the raid at Combahee Ferry, which liberated more than 700 slaves. No photographer credited, 1911

An Eglin Air Force Base F-35A Lightning II receives fuel from a KC-135 Stratotanker assigned to MacDill AFB approximately 100 miles off the Gulf Coast March 2, 2016 following the 58th Fighter Squadron's first successful munition employment at a nearby range. Airmen from the 33rd Fighter Wing were able to complete modifications to the aircraft ahead of schedule to enable the use of inert munitions instead of simulated weapons, advancing the fifth-generation fighter's syllabus and ensuring pilots receive the most comprehensive training before they support a combat-coded F-35A unit. The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters undergoing final development and testing...

Dr. Pierces' Tonic. While this tonic's claim to transform the listless invalid into a vigorous and healthy being might not have been tempered under the Food and Drugs Act, its opium and alcohol would have to be labeled after 1906. Besides manufacturing patented medicines and selling them through mail-orders, Ray Vaughn Pierce was considered a prominent doctor who founded a sanitarium and authored a home-diagnosis manual called, The People's Common Sense Medical Advisor in Plain English; or Medicine Simplified, which sold more than four million copies. He served in the 46th Congress in 1879-1880. His congressional bio says he "engaged in the manufacture and sale of proprietary medicines and established the Invalids' Hotel and Surgical Ins...

Bust of Mithras, circa 200 AD, found in London. Mithra is the Zoroastrian divinity (yazata) of covenant and oath. He is also a judicial figure, an all-seeing protector of Truth. The Romans attributed their Mithraic Mysteries to Persian or Zoroastrian sources relating to Mithra. However, since the early 1970s the dominant scholarship has noted dissimilarities, and those mysteries are now qualified as a distinct Roman product. Like most other divinities, Mithra is not mentioned by name in the Gathas, the oldest texts of Zoroastrianism and generally attributed to Zoroaster himself. As the divinity of contract, Mithra is undeceivable, infallible, eternally watchful, and never-resting

Neutrinos ("little neutron" in Italian, coined by Enrico Fermi) reveal themselves when one strikes an atom and generates a flare of light, but the event is rare. A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe.
