Inventions and Discorevies

 

A discovery is recognizing something that already exists for the first time, that nobody has found before,


Example:  how Christopher Columbus discovered the Americas.



An invention is creating something totally new with one’s own ideas and development. Although an invention is completely new to the world, the physical material needed for its production already exists, innovated from the ideas and experiences of the individual. Thus making inventions unique. Creating all the material into something with the concepts of + − × and ÷ is what invention is all about. 

Example: how Thomas Edison invented the light bulb.

The internet is a global system of interconnected computer networks that is used by billions of people worldwide. In the 1960s, a team of computer scientists working for the U.S. Defense Department's ARPA (Advanced Research Projects Agency) built a communications network to connect the computers in the agency, called ARPANET, the predecessor of the internet. It used a method of data transmission called "packet switching", developed by computer scientist and team member Lawrence Roberts, based on prior work of other computer scientists. 

This technology was progressed in the 1970s by scientists Robert Kahn and Vinton Cerf, who developed the crucial communication protocols for the internet, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), according to computer scientist Harry R. Lewis in his book “Ideas That Created the Future:(opens in new tab) Classic Papers of Computer Science(opens in new tab)” (MIT Press, 2021). For this, Kahn and Cerf are often credited as “inventors of the internet”.

In 1989, the internet evolved further thanks to the invention of the World Wide Web by computer scientist Tim Berners-Lee while working at CERN (The European Organization for Nuclear Research). According to CERN(opens in new tab), "the basic idea of the WWW was to merge the evolving technologies of computers, data networks and hypertext into a powerful and easy to use global information system." The development of the WWW opened up the world of the internet to everybody and connected the world in a way that it had never been before.

RELATIVE CLAUSES

Imagen
  Defining Relative Clause We use 'defining relative clauses' when we want to give more information about the person or thing we are talking about. Without that information, the sentence will be meaningless. Saying … “Send me the photo” is not the same as “Send me the photo which I took of you yesterday.” Examples… That's the woman who stole my coat. That's the man that I spoke to last week. Where is the apple that I told you not to eat? This is the cat which I adopted. The hospital where I was born is being knocked down. Remember… It contains essential information about the noun. If we eliminate the subordinate clause, the sentence does not make sense. We can substitute the relative pronouns 'which' and 'who' for 'that'. The pronoun can be omitted if it refers to an object. Non-defining Relative Clause We use non-defining relative clauses when we want to join two sentences into one. For example… The Queen will be 93 in April. Ella she loves skyd

The unreal conditional

Imagen
1. The Unreal Conditional is used when referring to unreal, imaginary or impossible conditions and their results. Both- If Clause and Result Clause, present the unreal result of the condition. Example:   If I lived in  palace , I would give parties all the time. ( But I don´t live in a palace, so I don´t give parties.) · If I had a car , I would drive everywhere. 2. The verb in the If Clause is shown in simple past tense. In the Result Clause the auxiliary Would + base form of the verb is used. Example:   If Luisa went to Cusco , she would spend a great time Note:  a. The If Clause uses the simple past tense, but the meaning does not refer to the past. · If I had money now, I would supply many things to myself. b. Do not use the auxiliary Would in the If Clause in present unreal conditional sentences. · If I bought some flowers to Mary, she would be happy. NOT: If I would buy ....... c. Use Were for all people when the verb in the If Clause is in the basic form (be). · If I were a king
