Internet Statistics In Germany
•Germany has the 6th highest number of internet users at 65,125,000 ▫This number accounts for 79.9% of the
population (81,471,834) and 3.1% of the worldwide users
▫In 2000 Germany only had 24,000,000 internet users
▫Worldwide there are 2,110,765,810 which only accounts for 30.5% of the total population
X-ray• On December 28, 1895, Wilhelm
Rontgen published a paper on a major discovery. The X Ray was invented by Germany scientists who examined cathode rays in 1875. Those scientists were Philip Lennard, Wilhelm Rontgen and Johann Hittorf. Mr. Rontgen is a physics professor who lived in Germany. He used Crookes tubes to study the electromagnetic rays. Crookes tubes are known to generate electrons to create x-rays by ionization of air. He named the ray as X because it is still unknown.
Jet Engine• Hans von Ohain obtained his patent on the jet
engine in 1936 • He was responsible for the first jet fighter
▫Heinkel He 118 ▫After WWII he moved to America
• Under his supervision the technology for VTOL aircraft was designed ▫Harrier ▫JSF-35
Harrier JSF-35
MP3• Invented by the
Fraunhofer Reaserch institue in 1993
• It is a form of file encoding ▫ Using lossy data
compression to minimize the size of the files
• It was a collaborative effort by several different organizations and is still being improved everyday
• Currently considered the Standard audio file
LCD Technology
•LCD technology was first discovered in 1888 by Friedrich Reinitzer
•It was later improved by Otto Lehmann which led to the development of simple LCD displays
•This technology has slowly progressed into the modern LCD TVs we have today
Radar• Christian Huelsmeyer
discovered that radio waves could be bounced off of metallic objects in 1904 ▫ He called this device the
telemobiloscope▫ Which was later
improved into what we know today as RADAR Radio Detection and
Ranging▫ He used the writings of
Heinrich Hertz to help him discover radar
Catscan• Godfrey Hounsfield built the
first CT scan machine in 1970 and it was first used in medical practice in 1971▫ CT stands for Computed
Tomography ▫ It views the object in slices
and creates a 3d image • In 1975 the first full body
scanner was built• CT scans are very widely
used with 72 million scans in the US in 2007
• CT scans use X-rays where MRIs use magnetic feilds
Programmable Binary Computer• Konrad Zuse created the
first programable binary computer in 1938▫ He called is the Z1 and
had about the same computing power of a simple pocket calculator
• Between 1938 and 1950 he developed 3 more computers Z2, Z3, Z4
• The computers were massive and required 4 people to assemble it
• Zuse also created software to help guide bombs
Auto Technology• Germany has always been a
pioneer in auto technology• The first gasoline powered
auto was built in 1889• Rudolf Diesel created the
diesel engine in 1893 and it still widely used today
• Germany has also been pioneers in car safety ▫ Accident avoidance
systems ▫ Adaptive cruise control ▫ Laminated glass▫ 3 point safety belt
