The Top 10 Scientific Discoveries that Changed the World

17 Jun

Back in February, after having a bad day, I shelled out $13 for the special National Geographic (get them for free via my Grandfather). 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.

Best example, I have the username and you don’t. I am keeping you out of my bank account. Noticed the lock next to the sign in.

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.
