  Milky Way : The Milky Way is (confined in with gravity) a massive disciplined system that is composed of uncounted stars, dust ,interstellar gases, plasma and massive disappeared things. In an ideal Milky Way contains from ten million to one trillion stars of which all revolve in a one centre of the gravity .Without isolated stars, there are a many constellations ,nebulae in the Milky Way. Almost of the Milky Way’s diameter from hundreds light years to thousands light years and the middle distance of Milky Ways is all but a million light year .Disappeared things are responsible for almost 90 % weight of the Milky Ways, although there have a great uncertainty of their existence and formation .More than 100 billion Milky Ways in our observation limits as a matter of fact. The death of the Milky Ways: The Milky Way comes forward to death when dearth of gases is precise at the time of new star’s creation .Scientists say, two kinds of milky ways are visible .One is Blue Milky Way and ...

 Structural road system is a such kind of scientific based sample of any road through which is done expanded the length of any road and curtailed the excessive cost of road maintenance acclimatizing environments.Besides, to keep space on either two sides of the road in consideration of pedestrian's safety and to evade accidents.Moreover, whether roads are possible or not to take the load of the vehicles that is needed to notice. To make effective plan/design of road and implementation of it are crucial.But then, it is very sorrowful for us that almost of the road of our country are never made in proper way following road constructional system in spite of our government's a high amount investment every year in this sector. Corruption is a main obstacle on it's development way.The authority from high stages to lower levels (contractors, raw materials suppliers, engineers) both road management system and constructional system are associated in corruption and burden of their ev...

    Atmosphere refers to layers mixed with different kinds of gases that surround the world and the world retains atmosphere   by the force of gravity. It’s main function is to absorb ultra- violet rays from the sun and its main purpose is to protect organism existence .Atmosphere retains temperature and warms the earth .Emission of augmentative warmth gases accelerate greenhouse effects that occurs global warming. Atmosphere becomes   flimsy increasing its height . Air is made up of the main three gases –nitrogen ,oxygen, argon and other gases are made up of by the combination of three gases .Besides, minimum chemical compounds are included in the air. Moreover, in the air the presence of these gases (mineral   vestige ,organic matter, pollen ,cocoons ,aerosols, sea spray, volcanic ash) are visible. The presence of amounts of gases in the atmosphere Name Amount Nitrogen 78.084% Oxigen 20.946...

 Now all over the world is facing Covid 19 crisis.  A massive crisis is now awaiting for the world. In where the world is being ended in smoke to confront with the crisis having stood up in the position how the world will deal with climate change. Global warming is increasing in such a way that will go five cores years back very soon that is beyond our imagination .In that situation no human beings will survive and wildlife as well as food chain will face imbalance. All gases, deleterious and inauspicious for nature and all carbon, nitrogen based molecules and their emission and influences upon nature and human beings go without saying how much inclement consequences will be. True fact is, In air pollution Bangladesh has taken the first position but before that place is occupied with Dilhi of India. Specially the dimension of air pollution of Dhaka is so extreme that to think to going out without musk is behind of our's imagination.The storm of dust flows away incessantly obvi...
