Gregor Mendel Science

Gregor Mendel was also a skilled beekeeper and studied the inheritance of traits in honeybees, though this work wasn't as well-known as his pea plant experiments. elaborate

Sun Dialing Science

The accuracy of a sundial depends not only on its design but also on the observer's precise location and the equation of time, which accounts for the Earth's elliptical orbit. elaborate

Bill Nye Science

Bill Nye's full name is William Sanford Nye. elaborate

Toxicology Science

The LD50, a common measure of toxicity, represents the dose of a substance that is lethal to 50% of a test population. It's not necessarily a precise measure for humans, as species can react very differently. elaborate

Automotive Materials Science Science

Some car parts, like bumpers, use a type of plastic called polyurethane that's also found in foam mattresses. elaborate

Scientists and Innovators Science

Marie Curie's research notebooks are still radioactive and require special handling. elaborate

STEM Science

The first computer bug was a real bug—a moth found trapped in a relay of the Harvard Mark II computer in 1947. elaborate

Geology Science

The largest known single crystal is a beryl crystal found in New Hampshire, measuring over 18 feet long. elaborate

Molecular Gastronomy Science

Molecular gastronomy utilizes techniques like spherification to create caviar-like spheres of flavor, often from unexpected ingredients. elaborate

Paleontology Science

Fossil dung (coprolites) can reveal a surprising amount about a dinosaur's diet, including the types of plants they ate and even the presence of parasites. elaborate

Louis Pasteur Science

Louis Pasteur's work on vaccines stemmed from his initial research on fermentation, showing a connection between microorganisms and spoilage. elaborate

Meteorology Study Science

Meteorologists use weather balloons carrying radiosondes to measure atmospheric conditions at different altitudes, and these balloons sometimes reach the stratosphere – bursting only when the thin air can no longer support them. elaborate

Carl Sagan Science

Carl Sagan's ashes are entombed in a small, Urn-shaped container which also holds a sample of soil from Mars. elaborate

Light Curing Science

Light curing, used in dentistry and other applications, relies on a process called photopolymerization, where light triggers a chemical reaction that hardens a liquid resin into a solid. elaborate

Modeling Science

Many models use specific posing techniques to make their bodies appear longer and leaner in photos, even if they aren't actually that tall or slender. elaborate

Citizen Science Science

Citizen science projects have helped discover new planets orbiting distant stars. elaborate

Psychology Science

The "bystander effect" describes the phenomenon where the more people present during an emergency, the less likely any one person is to help. elaborate

Neil Degrasse Tyson Science

Neil deGrasse Tyson's asteroid, 13123 Tyson, is named after him. elaborate

Crystal Growing Science

The color of a grown crystal can be dramatically altered by adding tiny amounts of impurities, even at parts-per-million levels. elaborate

Scientists/Inventors Science

Isaac Newton's work on gravity was partly inspired by an apple falling from a tree, but there's no evidence he was bonked on the head by it. elaborate

Alexander Fleming Science

Alexander Fleming's discovery of penicillin was partly accidental; he noticed the mold inhibiting bacterial growth on a contaminated petri dish. elaborate

Astronomy Science

There are more stars in the universe than grains of sand on all the beaches on Earth. elaborate
