Science And Environment

Hello Friends, Welcome back. As the Christmas is approaching near, all of us were planning to celebrate it and we also planning for the gifts that we want to present to our dear ones. But what about our most dearest one ........... What you planned to gift her? Still didn't understand. I am talking about our "Mother Earth".  The holiday season is full of good times with friends and family, with lots of food, treats, gifts, decorations, and more. But, have you ever thought about how much trash gets thrown away and how much energy is used during this time of year? What happens to the wrappers on all of the candy you get, the food scraps from your turkey dinner, the bows and gift wrapping from presents, the used up tape dispensers, the dried up wreaths and Christmas trees? Most of it gets thrown away and there's no getting around it, it's a lot of waste. You can help the environment this holiday season by using less stuff, less energy, and turning trash in...

  Hello Friends, Welcome Back, Today I am going to share some steps of keeping out earth green and pollution free. Today we all are concerned with our earth's bad condition which is going worst and more worst as the time is progressing. Today we all are listening about the global warming and the various effects of global warming on our lives. In this article I am going to discuss about various pollutants which is making our earth's condition bad. One of the primary pollutant i s   solid waste. Solid wastes are organic and inorganic waste  material such as product packaging, grass  clippings, furniture, clothing, bottles, kitchen  refuse, paper, appliances, paint cans, batteries,  etc. produced in a society, which according to individual perceptions does not have any value. Now the question arises how we can get rid of solid waste.  There are several steps to having an effective waste management strategy. This includes: 1.  Sou...

Hello Friends, Welcome Back, Well today I am going to tell you about the history of our vast and endless universe. How did it came into existence. Well you all will be amazed to know that our this vast universe had started from a point as small as our skin pores. Now we are seeing so many galaxies separated by thousands of light years, humongous stars, planets and uncountable solar systems, but this all started from a single point as small as our skin pore. Science has advanced to the point where we can infer something about the entire universe. This has been a great challenge considering how unimaginably vast the universe is. The countless stars you see in the darkest sky constitute merely 3000 neighbors out of about 300,000,000,000 stars in our galaxy, and as many as 100,000,000,000 galaxies exist in the universe. Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the beginning of this past cent...

Hello Friends, Welcome back. Today I am going to share my knowledge about black holes with you all. From my childhood I always remained fascinated with the universe and all its mysteries and always tried to know about it, answers to my general questions of my childhood about universe sometimes comes from my father or sometimes it is from a book. Still today I am curious to know about the various mysteries of the universe. And today I am going to tell you about one of those mysteries i.e   BLACK HOLES A black hole is an object that is so compact (in other words, has enough mass in a small enough volume) that its gravitational force is strong enough to prevent light or anything else from escaping. A black hole is born when an object becomes unable to withstand the compressing force of its own gravity. Many objects (including our Earth and Sun) will never become black holes. Their gravity is not sufficient to overpower the atomic and nuclear forces of their interiors, which res...

Does God exists? This is one of the biggest and mysterious questions of our life that we are always confronted with. Many of  us believe that God exists   but some of us don't believe in him and always arises questions on his existence. Even scientists denies the presence of God but today I am going to explain some of the reasons based on science that does God really exists or not.. But first consider this. If a person opposes even the possibility of there being a God, then any evidence can be rationalized or explained away.   1. Does God exist? The complexity of our planet points to a deliberate Designer who not only created our universe, but sustains it today. Many examples showing God's design could be given, possibly with no end. But here are a few: The Earth ...its size is perfect. The Earth's size and corresponding gravity holds a thin layer of mostly nitrogen and oxygen gases, only extending about 50 miles above the Earth's surface. If Earth were smaller,...

Hello Friends  Welcome back. Today I am going to tell you something about natural particle accelerators, how does they work and what are their uses? We all had heard about the particle accelerators or even read about them in our science books, such as Cyclotron and more recently all of us had heard about the LHC through various sources of media, whether it is a print media or through television.  These all particle accelerators are made by man. The question arises, What is a particle accelerator?  A  particle accelerator  is a device that uses  electric fields  to propel  charged   particles  to high speeds and to contain them in well-defined beams. An ordinary  CRT  television set is a simple form of accelerator. Had you ever heard or even think about the particle accelerators existing in nature?  Yes it is true, that nature has also its own particle accelerators and today in this topic...

Hello Friends, Welcome Back, Today we all are screaming "save forests, save earth" , but do we actually saving them or trying to save them. Just sit down calmly and give a thought upon it. Never has the planet been more in need of forests. Never have the forests been under greater pressure than they are today. As man learnt about nature he started to interfere with the laws of nature. He cut off the forests for agriculture and tamed wild animals for his food and clothing. The history of the growth and spread of civilisation is also the story of deforestation. Farming which started some 12,000 years ago, invariably took place on land previously covered by forests. Agriculture, in turn, was was a precondition for the growth of cities. Man was able to conquer nature, yet he cannot control it. A balance exists between all living and non-living things in nature. Ecological disasters are bound to happen if there is any disturbance in the natural equilibrium. Increased ind...

Hello friends, Welcome back. TIGER : At first as we think of this creature, our mind fills with fear from this enormous gigantic dangerous predator. But if we think for a moment then we realize that not this creature is dangerous for us but we are proving dangerous for the existence of this creature. At the turn of the 20th century, according to sources, India had an estimated 40,000 tigers in the wild. In 2002, based on pug mark census, this number was 3,642. As per the monitoring exercise by Wildlife Institute of India in association with National Tiger Conservation Authority (NTCA), Government of India using camera traps, in 2008 we were left with only 1,411 tigers. This number is so small that they will be gone soon if we don’t wake up to the crisis. The tiger is not just a charismatic species. It’s not just a wild animal living in some forest either. The tiger is a unique animal which plays a pivotal role in the health and diversity of an ecosystem. It is a top predato...

Hello friends, Welcome back. Today I am going to tell you about one more new discovery in the field of science. It is a quite amazing discovery and a very useful one also Electronic components that exploit the phenomenon of superconductivity could allow us to study the collective behaviour of large numbers of neurons operating over long timescales. That is the finding of scientists in the US, who have shown how networks of artificial neurons containing two Josephson junctions would outpace more traditional computer-simulated brains by many orders of magnitude. Studying such junction-based systems could improve our understanding of long-term learning and memory along with factors that may contribute to disorders like epilepsy. The human brain consists of some 100 billion nerve cells known as neurons, each of which receives electrical inputs from a number of its neighbours and then sends an electrical output to others – a process known as "firing" – when the sum of its ...

Hello Friends, Welcome back, Today we all are talking about the world's end in 2012. Many films has been made and released on this topic. We all know about the Mayan's calendar and their horrifying predictions of the end of Earth and off course the human race. Today I am going to discuss with you all those reasons, on which Mayan's did the predictions and I will prove them baseless and purely bull shit. So following are the ten reasons which Mayan's described as the basis of of their predictions of the Earth's end. The ten top 2012 doomsday scenarios: 10. Changes in the Sun's magnetic field will lead to powerful flares. So what else is new under the sun? The sun goes though a well-documented 11-year sunspot cycle that is driven by its magnetic field entangling, reforming and flipping polarity. Yes, the peak of the next cycle is in 2012 (or 2013), and some predictions suggest it might be 30 to 50 percent stronger than the last peak. But experts sa...
