Electromagnetic Induction [1831]
A man named Michael Faraday
discovered a way to generate
electricmotive force from a
conductor and a magnet. This
would go on to become the very
basis of how almost all of our
electrical power is generated today.Penicillin [1928]
Alexander Fleming was the first to be able
to isolate the effects of penicillium mould.
This effect of supressing bacterial growth
will soon come to use as the first group of
antibiotics that will be effective against the
normal baterial infections.ICE: Internal Combustion Engine [1794]
The ICE was the first engine to run on
liquid fuel. Today, ICEs drive some of
the largest electric generators that
power electric grids.The World Wide Web [1991]
Starting in 1980, Tim Berners-Lee created
the WWW project at CERN. His invention
of the HyperText Treansfer Protocol (HTTP)
and the HyperText Markup Language
(HTML) are the foundations of today's
webpages.Steam Engine [1781]
James Watt patented a steam engine that
produced rotary motion with the power
of 7500W. It was the first steam engine to
make use of steam at a pressure just above
atmospheric to drive the the piston.Nitrogen Fixation [1863]
As one of the most important biochemical
processes on the Earth, Hermann Helliriegel
is credited to the discovery of the tubercles
on the roots as the agency through which
nitrogen fixation takes place.Refrigerator [1856]
The first practical vapor compression
refrigeration system was built by James
Harrison. His original patented version
was for compressing ether, alcohol, or
ammonia.Pressure Cooker [1679]
A French physicist named Denis
Papin accidentally created the first
pressure cooker he named "steam
digester" in an attempt to cook
food more quickly. Inmodern
kitchens, pressure cookers
become essential to certain
dishes thatwould otherwise take
a long time.Windows XP [2001]
Perhaps the most familar version of the
Microsoft Windows OS in this generation
is the Windows XP, codenamed "Whistler".
This version was a major advance from the
MS-DOS based versions of Windows, giving
a significant upgrade in security, stability,
and efficiency. It also had a greatly
improved GUI.Oculus RIft [2012]
The Oculus RIft is a virtual reality headset
that was widly popular from its kickstarter
page and even after its launch. It was, to
many, a big step into the world of virtual
reality and its related hardware.
