The industrial revolution

Source a

In 1733, Mr. John Kay of Britain improved the loom used for weaving to such an extent that the demand for spinning thread increased drastically. From the business world it is clear that the greater the demand for a specific product (e.g. spinning thread), the better the price that can be obtained by the manufacturer (e.g. the spinner) for his product.

James Hargreaves was a woodworker and spinner from Lancashire in Britain. One day, his daughter, Jenny, knocked over the spinning wheel in the overcrowded house in which he, his wife and their seven children operated their cottage industry.

James realised that more spindles could be mounted on the axle and that more threads could therefore be spun at the same time. Hargreaves names his new invention the Spinning Jenny.

One Spinning Jenny, which had eight spindles, could do the work of eight people at the same time. Spinners who feared job

lessness broke into Hargreaves’s house and destroyed the Spin

ning Jenny. Hargreaves moved to Nottingham and opened a factory with larger and better spinning machines. His success with the Spinning Jenny motivated other inventors to also begin experimentation. In this way, a number of new and improved machines were developed.

The next step was the development of machines that could be operated with water power and steam power.

Written exercise:

  • Complete the following sentences on Source A.

The development of the Spinning Jenny was caused by an accident, namely that


The consequence of the accident was that Hargreaves got the bright idea to

The use of machines increased production, necessitating good roads for fast transport from the farm (e.g. fresh vegetables or wheat for bread) or factory (e.g. clothes) to the market.

John Loudon McAdam is still respected as a master road builder today. It is thanks to him that a network of excellent roads was built in Scotland and Britain.

Activity: chronology

All the following facts on McAdam are correct, but they are not in the correct sequence. Read through the points and rearrange the facts so that they follow on one another logically.

1. He returned to Scotland at the age of 27.

2. When John was 14, his father died and he went to live with his uncle in New York.

3. McAdam was born in Scotland in 1756.

4. When John was a child, he enjoyed making roads for his toy carriages.

5. Even after his death, his techniques for building roads remained available in the three books that he wrote on the topic.

6. In New York, McAdam eventually became a wealthy merchant.

7. Back in Scotland, McAdam began to experiment with road building on his own estate in Ayrshire.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
