History of joule
History of joule
James prescott joule was an outstanding British physicist. He is best known for his research in electricity and thermodynamics. Amongst other things, he formulate a law for the heating effect of electric current.He also verified experimentally the law of conversation of energy and discover the value of mechanical equipment of heat .The unit of energy and work called joule ,is name after him.
Nitrogen cycle
Nitrogen cycle
Nitrogen gas makes up 78% of our atmosphere and nitrogen is also a part of many molecules essential to life like protein nucleic acid (DNA and RNA) and some vitamins.
Nitrogen is found in other biologicall -y important compounds such as alkaloids and urea too. Nitrogen is thus an essential nutrient from all life forms and life would be simple if all these life-forms could use the atmospheric nitrogen directly. However, other than a cube from of bacteria life forms are not able to convert the comparatively inert nitrogen molecules into form like nitrates and nitrites which can be taken up and used to make require molecules.
These nitrogen fixing bacteria may be free living or be associated with some spices of dicot plants. Most commonly the nitrogen fixing bacteria are found in the root of legumes (generally the plants which give us pulses)in special structures called root nodules.
Other than this bacteria,the only other manner is which the nitrogen molecules is converted to nitrate and nitrite is by the physical process.
During lightning,the high temperatures and pressures create in the year convert nitrogen into oxide of nitrogen. These oxides dissolved in water to give nitric and nitrous acid and fall on land along with these are there in utilised by various life forms.
What happens to the nitrogen once it is converted into forms that can be taken up and used to make nitrogen containing molecules?
Plants generally take up nitrites and nitrates and convert them into amino acids which are used to make proteins. Some other biological pathway are used to make the other complex compounds containing nitrogen and other complex compounds .
These protein and other complex compoundare subsequently consumed by animals. Once the animals for the plant dies,other bacteria in the soil convert the various compound of nitrogen back into nitrites and nitrates.
A different type of bacteria converts the nitrites and nitrates into elemental nitrogen does there is the nitrogen cycle in nature in which nitrogen pass from this element from in the atmosphere into simple molecules in the soil and water which get converted to more complex molecules in living being and back again to the simple nitrogen molecules in the atmosphere.

Water cycle
Water cycle
Water cycle is the most important cycle on the earth . Water is the life of Humans , excluding humans, plants and animals also need water to live. Water cycle help us to maintain the capacity of water on the earth. On the earth there is a 71% water and 29% of land . From 71% of water 97.5% is saline water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface that human can drink. So we can understand the the importance of water.
Saline water is used to produce electricity , it contain large amount of salt that's why it can't use for drinking as a resource.
So now we want to come on our topic water cycle you have learn this in 5th standard that what is water cycle but now we will learn it in the deep:
The process in which water change into water vapour is called as evaporation.
The process by which air get convert into water droplets is called as condensation.
The process in which solid get convert into air without changing in water state is called sublimation.
In the process instead of water droplets ,snow come out from the cloud , called precipitation.
The process in which the plants leaves produce water vapour this process is called as transpiration.
By the transpiration of plant water goes up in the atmosphere and form clouds with the help of evaporation. Then clouds run of the snow this snow stuck on the mountain and at the time of sunny weather it get converted into water from long distance water come back in the ocean and plants absorb that water, this goes on & our water cycle form. It's also called a transpiration water cycle.
By The evaporation ocean water get converted into gaseous state and this air mix in the atmosphere and form a cloud ,by the precipitation the snow runs from the cloud and stuck on the mountain again in the sunny weather is converted into water and come back into ocean,again this ocean water turn into vapours and come down as snow and water droplets and water cycle take place.
peptic Ulcer and Nobel prize
Peptic ulcer and Nobel prize
For many years , everybody used to think that peptic ulcer which causes acidity related pain and bleeding in the stomach and deudanum,were because of lifestyle reasons .Everybody thought that stressful life lead to a lot of acid secretion in stomach, and eventually causes peptic ulcers.
Then to Australian made a Discovery that bacterium, helicobacter pylori was responsible for peptic ulcers.

Australian doctors |
Reborn Bahrain -born 1937 a pathologist from preth ,Australia, saw this small curved bacteria in the lower part of the stomach in many patients. He notice that signs of inflammation were always present around this bacteria.Barry Marshall born 1951 a young clinic fellow, become interested in warrants finding and succeed in cultivating the bacteria from the source.

For this achievement Marshall, and Warren received the Nobel prize for psysiolodgy and medicine in 2005 |

Happy time , receiving Nobel prize |
Dolton atomic theory
Dalton atomic theory
According to Dolton atomic theory all matter whether an element a compound or a mixture is composed of small particles called atoms .The postulate of this theory may be stayed as follow:
- All matter is made of very thin particles called atoms which participated in chemical reaction.
- Atoms are indivisible particle which cannot be created or destroyed in the chemical reaction.
- Atoms of a given element are identical in mass and chemical properties.
- Atoms of different elements have different mass and chemical properties.
- Atoms combine in the ratio of small whole numbers to form compound.

Categories of cast
Brahman divided cast into four categories
- Brahman
- Kshatriya
- vaishya
- Shudra
Brahman
{ Vishnu is the preserver of the universe, while Shiva's role is to destroy it in order to re-create. Brahma's job was creation of the world and all creatures. His name should not be confused with Brahman, who is the supreme God force present within all things. Brahma is the least worshipped god in Hinduism today}

Why Babasaheb Ambedkar seat outside the classroom?
Why Babasaheb Ambedkar seat outside the classroom?
Because babasaheb Ambedkar was dalit and that time Hinduism was followed by many peoples and they believe on black magic, they doesn't treat people equally, bramhan divided The peoples on cast basis and rituals.
Brahmin divided the people on the basis of caste that are:
* In detail we will learn soon.
Babasaheb Ambedkar biography
Babasaheb Ambedkar biography
Babasaheb Ambedkar was from mahu .The childhood of this great personality was very hericuras .He was the son of Ramji Ambedkar and bhimabai.Babasaheb Ambedkar biography was very heart touching because no other personality take risk as he take ,
Frist of all we will learn his childhood:
As we know that babasaheb Ambedkar born at mahu, district-indor .
Babasaheb was interested in studies so his father Ramji request to the teacher of pathsala to allow Bhimrao to enter pathsala to study , after hard discussion with his father teacher allow . But there is another problem the students of that pathshala was not behaving good with Ambedkar because he was dalit .
Teachers also not allow to enter in classroom , Bhimrao seat outside the classroom and listen the the lessons that was teach classroom ,
Teachers also not allow to enter in classroom , Bhimrao seat outside the classroom and listen the the lessons that was teach classroom ,
At the time when teacher ask questions no one student can answer ,but babasaheb was able to answer . You can See that babasaheb was seat outside the room and answering the questions , this is the sign of brilliant student.
