Nikola Tesla was obsessed with the number 3 and often did things in sets of 3.

Charles Darwin ate every animal he discovered during his travels, including iguanas and giant tortoises.

Thomas Edison was afraid of the dark and always slept with a light on. After a while, he switched from gas lights to electric lights since he made electric lighting available.

Leonardo da Vinci was ambidextrous and often wrote backwards. He was also known for demonstrating feats of strength.

Rosalind Franklin’s X-ray crystallography data was used by James Watson and Francis Crick to discover the structure of DNA, but she was not given credit until after her death.

Astronomer Carl Sagan wrote a novel, “Contact,” which was later turned into a movie starring Jodie Foster.

Neil deGrasse Tyson was once a competitive ballroom dancer.

Werner Heisenberg, the physicist behind the Heisenberg Uncertainty Principle, was also a talented pianist.

The father of microbiology, Antonie van Leeuwenhoek, was also a successful cloth merchant.

Margaret Mead, an anthropologist, once famously said, “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.”

Marie Tharp, a geologist, helped map the ocean floor, and her work revealed the Mid-Atlantic Ridge and helped prove the theory of plate tectonics.

Edwin Hubble, the astronomer who discovered the expanding universe, was also a skilled basketball player and played on the University of Chicago team.

Ada Lovelace, a mathematician who is considered the world’s first computer programmer, was also an accomplished musician and writer.


Richard Feynman, the Nobel Prize-winning physicist, was known for playing bongos and cracking safes as hobbies.

Max Planck, the physicist who originated quantum theory, was also an accomplished pianist.

Alfred Wegener, the scientist who proposed the theory of continental drift, was not widely accepted in his time but is now recognized as a pioneer in the field of geology.

Margaret Hamilton, a computer scientist, led the team that developed the software for NASA’s Apollo missions and coined the term “software engineering.”

Rosalyn Yalow, a physicist and medical researcher, was the first woman to win a Nobel Prize in Physiology or Medicine in 1977.

Alan Turing, the father of computer science and artificial intelligence, was also a skilled long-distance runner and cracked the Nazi’s Enigma code during World War II.

Katsuko Saruhashi, a geochemist, was the first woman to earn a doctorate in chemistry from the University of Tokyo and discovered the harmful effects of nuclear testing on the environment.

Paul Erdős, a mathematician, was known for his nomadic lifestyle and collaborative work with other mathematicians around the world.

Jocelyn Bell Burnell, an astrophysicist, discovered pulsars but was not awarded the Nobel Prize for her work, which went to her male supervisor instead.

A human sneeze can travel up to 100 miles (160 kilometers) per hour.

The strongest muscle in the human body is the masseter muscle, which is used for chewing.

Human hair can stretch up to 30% of its length when wet.

The human nose and ears continue to grow throughout a person’s entire life.

The human body has enough fat to make 7 bars of soap.

The human body contains enough iron to make a 3-inch (7.5 cm) nail.

The human heart creates enough pressure when it pumps blood to squirt blood up to 30 feet (9 meters) away.

The human body has enough salt to fill an average-sized salt shaker.

The human body can produce about a quart (1 liter) of saliva per day.

The liver is the only organ that can regenerate itself completely.

The human body produces about 25,000 quarts (25,000 liters) of blood in a lifetime.

The human body has enough carbon to make 900 pencils.

Human eyes are capable of distinguishing over 10 million different colors.

The average human farts around 14 times a day.

New Chemicals

In 1965, the CAS Chemical Registry System listed 211,934 synthetic chemicals. In 2006, that number rose to 88,758,285 and it’s still growing. Many of the chemicals are in products you use everyday from cosmetics to plastic toys.

Many soak through our skin or are breathed in and can be detected inside our bodies. For instance, researchers sprayed the common household oil, WD-40, on volunteers’ fingertips, and detected it in their blood five minutes later.

The average American male has a sperm count 75% lower than 40 years ago. Could this be partially due to these chemicals?

The Extent of Human Capacity

We remember one trillion things in our lifetime.

Computer scientists say our brains have a storage capacity approximately the same as an 11-terabyte hard drive, which with current solid-state technology can be stored in an area about the size of a fingertip.

Our eyes are each equivalent to a 137-megapixel camera, roughly ten times higher resolution than a typical modern digital camera.

These comparisons are a bit rough, because humans are made from wetware, not hardware. For instance, the retina has much greater sensitivity near the center than at the edges, while a camera has uniform sensitivity. The memory of a hard drive is digital. Each ‘cell’ in a hard drive can hold a one or a zero. Each cell in the human brain is more of an analog mechanism, firing or not based on many input factors.
