World Changing Science Discoveries : That have Changed the World History


Here are the top 10 most important scientific discoveries that changed the world all taken from the master list of 100 from National Geographic.



1.  Nanolithography (1999) 
Nanolithography is a way of manipulating matter on the scale of individual atoms in order to create circuit boards fro a variety of electronic. Basically, this helped in making computers smaller and computer programs. I don’t really understand it but it sounds cool and it is why we have cell phones, computers, and GPA systems.


2. Carbon Nanotubes (1991)
Carbon nanotubes are made up of rolled sheets of carbon atoms. The tubes may find use in tiny electrical components. One property of carbon nanotube is their strength. Their resistance to stress is five times that of  steel.


3.  World Wide Web (1990) 
I don’t really need to explain this one. Only in the face that it has changed everyone’s life. Basically, it links us together as human beings and is the whole reason for story telling. We can tell stories to everyone share ideas and research. We can also do things that destroy this idea by playing games or shopping online. The web connects us to everything.


4. Buckyball (1985)
Scientific name: Buckminterfullerene or Fullerene, for short
That molecules form geometrically regular cages and form a dome, which is a construction made of lattice of triangles.



5. Global Positioning System or GPS (1978) 


6. Personal Computer (1977) 

7. Augmented Reality
Augmented reality is designed to enhance the real world by superimposing audio, visual, and other elements onto your senses. Used in GPS and smart-phones. Best example is from the 1988 film Who Framed Roger Rabbit. Another example, is the yellow arrows that announcers use on televised football games when analyzing a play.
  

8. Public Key Cryptography (1976) 
A certificate authority simultaneously create a public and a private “key”. Much as a key unlocks a door, these keys are particular values that unlock encrypted data. The private key is given only to the person requesting it, and the public key is made publicly available. The private key is used to decrypt information that has been encrypted with the public key. This happens so that data is remind protected.


9. Molecular Electronics (1974)
Refers to the use of molecular components to build electronic devices.

10. Cell Phones (1973)
We all have a cell phone, no need to explain this one.
 

Here’s a look at some more discoveries that have changed the world. It’s nearly impossible to rank their importance though.


Penicillin

 Everybody knows the story – or at least, should – the brilliant yet notoriously absent-minded biologist Sir Alexander Fleming was researching a strain of bacteria called staphylococci. Upon returning from holiday one time in 1928, he noticed that one of the glass culture dishes he had accidentally left out had become contaminated with a fungus, and so threw it away. It wasn’t until later that he noticed that the staphylococcus bacteria seemed unable to grow in the area surrounding the fungal mould. Fleming didn’t even hold out much hope for his discovery: it wasn’t given much attention when he published his findings the following year, it was difficult to cultivate, and it was slow-acting – it wasn’t until 1945 after further research by several other scientists that penicillin was able to be produced on an industrial scale, changing the way doctors treated bacterial infections forever. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections.

Oxygen


Discovered by: Carl Wilhelm Scheele
Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had discovered it by about 1772. Scheele called the gas “fire air” because it was the only known supporter of combustion, and wrote an account of this discovery in a manuscript he titled Treatise on Air and Fire, which he sent to his publisher in 1775. However, that document was not published until 1777. Meanwhille, oxygen was also identified by Joseph Priestly in 1774. Priestly discovered a colourless gas from heated red mercuric oxide. He found this gas was highly combustible. He called it dephlogisticated air. Priestly shared his discovery with the French scientist Antoine Lavoiser. Lavoiser was able to show oxygen supported animal life respiration.

Gravity

Discovered by: Isaac Newton
Isaac Newton, an English mathematician and physicist, is considered the greatest scientist of all time. Among his many discoveries, the most important is probably his law of universal gravitation. In 1664, Newton figured out that gravity is the force that draws objects toward each other. It explained why things fall down and why the planets orbit around the Sun.

Fingerprints


Discovered by: Evangelista Purkinje
The discovery that fingerprints are unique to each individual, are left behind on objects a person touches and can be lifted off those items is nothing short of miraculous. This discovery completely changed the way that law enforcement conducted investigations. In today’s modern age, Jack the Ripper would eventually be caught. Even though it was 1823 when Jan Evangelista Purkinje noticed how unique our fingerprints are, it took some time for law enforcement to figure out ways to use this knowledge. Today, this discovery is used in everyday police work.

Electricity


Discovered by: Michael Faraday
If electricity makes life easier for us, you can thank Michael Faraday. He made two big discoveries that changed our lives. In 1821, he discovered that when a wire carrying an electric current is placed next to a single magnetic pole, the wire will rotate. This led to the development of the electric motor. Ten years later, he became the first person to produce an electric current by moving a wire through a magnetic field. Faraday’s experiment created the first generator, the forerunner of the huge generators that produce our electricity.

Alien Life


Discovered by: NASA
NASA’s paper, along with pictures of the microscopic earthworm-like creatures, were published in Feburary,2011 in the peer-reviewed Journal of Cosmology. A NASA Scientist Richard Hoover opened fragments of several types of carbonaceous chondrite meteorites, which can contain relatively high levels of water and organic materials, and looked inside with a powerful microscope. He found bacteria-like creatures that he calls “indigenous fossils,” which he believes originated beyond Earth and were not introduced here after the meteorites landed. “He concludes these fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies,” said the study. “The implications are that life is everywhere, and that life on Earth may have come from other planets.” The journal’s editor in chief, Rudy Schild of the Center for Astrophysics, Harvard-Smithsonian, said Hoover is a “highly respected scientist and astrobiologist with a prestigious record of accomplishment at NASA.”  Earlier in december 2010 NASA began to tease us with tantalizing hints regarding the Cassini-Huygens spacecraft– which is currently sending back massive amounts of data from Saturn—had confirmed the existence of microscopic life on Saturn’s moon Rhea. Well then that would be the first example of extra-terrestrial life. That study drew plenty of criticism, particularly after NASA touted the announcement as evidence of extraterrestrial life. Scientists are currently attempting to replicate those findings.
