The ibm pc

In july of 1.980 IBM ( international bussines machine ), created the ibm pc, the personal computer most successful of all time.The start of this decade marked this rising tensions of the cold war.Also, made public the existence of AIDS.
This success was not expected by IBM because ibm created the computer fastly and buying components of low-end to other manufactures so that ibm pc didn´t absorb part of the market from more powerful computers ibm.The operating system on the ibm pc was hired to microsoft.
During the years 1.980 IBM forged four nobel prizes.

REPERCUSSION IN THE DAILY LIFE:

-With the marketing of the pc, informatics stopped being a hidder and mysterious science without any regard for the majority of people, to become a handy utility.Later we had to depend on it.

What do you think?

Is there any truth in this? How can imagination help scientists? Your opinions, please

Electron

The discovery the electron was made in 1897 by J. J. Thomson at the Cavendich Laboratory at Cambridge University (England), while he was studying cathode ray tubes.

The electron is a fundamental subatomic particle that carries a negative electric charge.
Electrons make up atoms together with protons and neutrons. When the electrons are not part of the structure of atoms are moving freely in vacuum. When free electrons move, there is a net flow of charge, and this flow called electric current

Electrons have an electric charge of -1,602x10-19 coulumb and a mass of 9.11x10-31 Kg.

In everyday live the electrical current in our homes is caused by electrons moving. The cathode ray of a television is based on in a electron beam.
In industry the electron beams are used in solders.
In medicine is used in radiation therapy for treatment of superficial tumours…
