1635 – Robert Hooke – bio

Robert Hooke was born in 1635 on the Isle of Wight in England. He was known as an architect and philosopher, but made contributions in many fields. He discovered Hookes Law of elasticity which describes the compression and extension of springs. He collected observations made with magnifying lenses, of both small objects and distant objects, […]

-3500 – glass

Naturally occurring volcanic glass (obsidian) was use before we learned to make glass around -3,500 in Egypt and Mesopotamia. The earliest form of glass made by humans was probably glazes that were used on ceramic pots. By mixing crushed quartz with calcite (calcium carbonate) from limestone, a solution is produced which can be fired into […]

1632 – van Leeuwenhoek – bio

Antony van Leeuwenhoek was born in Delft, the Netherlands in 1632 and is known for creating the field of microbiology. While he did not invent the microscope, he worked to improve it and was the first to document the world of single celled organisms. Van Leeuwenhoek learned to work with glass and discovered that by […]

Magnetic Resonance Force Microscopy

MRFM (Magnetic Resonance Force Microscopy) is similar to MRI (Magnetic Resonance Imaging) but with resolutions that are one hundred million times better. It offers three dimensional imaging of live biological samples at the extreme limits of microscopy. Researchers at IBM developing this technology have been able to create a 3D image of a virus. A […]

1595 – microscope

While optics and the principles of magnification had been studied for hundreds of years, the first real microscope was crafted by three lensmakers in Holland around 1595. PRECURSOR: SUCCESSOR: 1608 – telescope 1632 – van Leeuwenhoek
