Starting in 1931 with the invention of the electron microscope, the nanoworld became visible to us. The nanoworld contains items as small in diameter as 1 micrometer (1 micron) to a diameter 1,000 times smaller, a diameter of 1 nanometer. The nanoworld includes the smallest single celled organisms, the smallest bacteria as well as viruses,

With the invention of the microscope, humanity became aware of the microworld which is defined as 1 to 1000 microns. A micron is equal to one thousands of a millimeter. A cell is about 10 microns wide. Paper is about 100 microns thick. The unaided human eye can see items as small as 50 microns,

The earliest known magnification dates back to the first century. These simple early magnification devices consisted of using natural crystals or a glass globe filled with water. It is reasonable to assume the use of natural crystals for magnification was around for many thousands of years. One possible specimen is the Nimrud lens dating back

7,000 Generations Ago All humans today share a single grandma, circa 175,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup L genes — from our X chromosome. She was one of many thousands of women living in eastern Africa. Many maternal lines survived for many generations but ultimately over time
11,000 Generations Ago All humans today share a single grandpa, circa 275,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup A genes — from our Y chromosome. He was one of many thousands of men living in eastern Africa. Many paternal lines survived for many generations but ultimately over time

The “out of Africa” migration took place in many waves of which two are widely recognized: 130,000 to 100,000 BCE, and the Southern Dispersal around 70,000 to 50,000 BCE. Through genetic DNA testing we know that none of the genetic differences prior to circa 70,000 BCE exist in today’s humans.

Genus Homo: Rapid brain growth in our human ancestors started about 800,000 BCE. Now, by rapid brain growth we mean about 600,000 years! Larger complex brains helped early humans to survive. They interacted with each other and their surroundings in new and different ways.

70,400 Generations Ago (from 2020 CE) By about 1.76 million BCE, early humans began to create hand axes. They would strike really large flakes, then continue to shape them around the edges. On the right, the hand axe pictured dates to circa 1.1 million BCE. It was found at Isampur, India.
