Most societies that developed in ancient civilizations were centered around some form of imperial administration and Imperial Rome (31 B.C.E.-476 C.E.) and Han China (206 B.C.E.-220 C.E.) were no different in this sense. Both civilizations had a network of cities and roads‚ with similar technologies that catalyzed cultural amalgamation and upgraded the standard of living‚ along with comparable organizational structures. Additionally‚ both civilizations had problems managing their borders and used

Edward Jenner does not deserve the greater credit in his discovery compared to both Louis Pasteur and Janssen & Hans. One thing I truly agree with is that the discovery by Edward Jenner was timely as small pox is now a thing of the past and the many deaths associated with the disease are now forgotten. However‚ refusing to give even bigger credit to the discovery of the microscope by Janssen and Hans. Louis Pasteur is one of the fathers of modern medicine. Without his work and discoveries in the

Mission 1 History of Biology Mission 1 of the game‚ “History of Biology” is on the scientist‚ Zacharias Janssen‚ who was born in 1580. Janssen was a Dutch spectacle-maker from Middelburg‚ credited with inventing the first microscope‚ which at the time was a tremendous increase in technology and allowed for detailed drawing‚ sketching‚ and recording. His microscope was very simple‚ hand-held‚ and consisted of three draw tubes with lenses inserted into the ends of the flanking tubes. The lens for

the invention of the microscope when they discovered how to grind lenses during the 1300’s‚ and as a result‚ created the first spectacles. The first microscope was developed in 1590 by two Dutch lens grinders and spectacle makers Hans Janssen‚ father‚ and Zacharias Janssen‚ son‚ when they put two grinded lenses inside a tube. Later in the 1700’s‚ many discoveries were made to improve the microscope. One was that lenses combining two types of glass could reduce the chromatic effect the previous microscopes

Their development is credited to three individuals: Hans Lippershey and Zacharias Janssen‚ who were spectacle makers in Middelburg‚ and Jacob Metius of Alkmaar.[4] Galileo heard about the Dutch telescope in June 1609‚ built his own within a month‚[5] and greatly improved upon the design in the following year.

SCIENTIFIC INVENTION ASSEMBLY LINE: Primitive assembly line production was first used in 1901 by Ran some Eli Olds (1864-1950)‚ an early car-maker (he manufactured the Oldsmobile‚ the first commercially successful American car). Henry Ford (1863-1947) used the first conveyor belt-based assembly-line in his car factory in 1913-14 in Ford’s Highland Park‚ Michigan plant. This type of production greatly reduced the amount of time taken to put each car together (93 minutes for a Model T) from its
