Apart from plants, animals and animals, we see different things around us. We see the sun, moon and stars in the sky. But there was a time when these things were not there. That time was before the Big Bang event. At that time there was neither time nor space. 12 to 14 billion years ago, our entire universe was confined to a single point. Now the biggest question is that when nothing existed in the world, how did so many things come into existence?  We will try to answer these questions through Big Bang theory. Big Bang      The Big Bang theory was proposed by Georges Lemaître in 1927. In 1929, a scientist named Edwin Hubble analyzed and studied this theory. Stephen Hawking explained it like this, about 15 billion years ago, the entire universe was reduced to a single point. Or simply understand that the particles and energy due to which the creation of the whole world became possible, were included in a small ball-like thing. Then suddenly an event happened and the ...

In economics, a luxury good (or upmarket good) is a good for which demand increases more than what is proportional as income rises, so that expenditures on the good become a greater proportion of overall spending. Luxury goods are in contrast to necessity goods, where demand increases proportionally less than income. Luxury goods is often used synonymously with superior goods. Definition and etymology The word "luxury" derives from the Latin verb luxor meaning to overextend or strain. From this the noun luxuria and verb luxurio developed, "indicating immoderate growth, swelling, ... in persons and animals, willful or unruly behavior, disregard for moral restraints, and licensciousness", and the term has had negative connotations for most of its long history. One definition in the OED is a "thing desirable but not necessary". A luxury good can be identified by comparing the demand for the good at one point in time against the demand for the good at a differ...

A transition is any event in life that alters your plans, your place in that plan, or your sense of purpose. Transitions can be stressful, and come with feelings of fear, anxiety, and anger. Coping mechanisms and self-care can help you navigate life transitions successfully. It may be cliché, but if there’s one constant in life, it’s change. We all change as we get older and go through different seasons in life. But that change, and the transitions it brings, can be really stressful. While transitions can be stressful, apprehension about the transition can even be scarier than the change itself. But by recognizing the transition period you’re in, understanding why it’s challenging for you, and having coping mechanisms to get through it, you can learn to successfully navigate the various transitions in your life. Typical Feelings During a Major Life Transition All of it brings a level of uncertainty that’s roiling with a gamut of uncomfortable feelings, thoughts and physical se...

From time to time, we face smaller or bigger obstacles in our life. All people need to deal with challenges and failures on their way, and their attitude towards those challenges plays the most important part. The person with positive attitude towards obstacles gradually becomes stronger and more successful. And in contrary, the person with negative attitude becomes more and more depressed, weak and unhappy. Here is a story about an inspiring challenge. Mbah Sadiman, the Figure Behind the 11,000 Plants on the Slopes of Mount Lawu. Sadiman or familiarly called Mbah Sadiman (68) is a figure who is still active in protecting and caring for the environment around the slopes of Mount Lawu, Central Java. Even though he is no longer young, this does not prevent him from continuing to contribute to protecting the environment. For more than 20 years or since 1996, Sadiman has devoted himself as a silent worker in restoring ecosystems on the slopes of Mount Lawu. At least 250 hectares of land in...

  The human body is made up of all the living and nonliving components that create the entire structure of the human organism, including every living cell, tissue and organ. On the outside human anatomy consists of the five basic parts, the head, neck, torso, arms and legs. However, beneath the skin there are countless biological and chemical interactions that keep the human body machine ticking over. For the human body to exist on its own as a self-sustaining entity, it is made of eleven elements in total as macro and micro constituents or nutrients. The first six major elements are carbon, hydrogen, oxygen, nitrogen, calcium and phosphorus. The next five elements in minute requirements are potassium, magnesium, sulfur, sodium and chlorine. A deficiency in any of these nutrients will result in acute health problems. Rickets is caused by lack of calcium and phosphorus. Goiter as the enlargement of the thyroid gland is caused by a lack of the element iodine. Sickle cell anemia is ca...

  If we look up at the Britannica dictionary, it’s said nature is the physical world and everything in it (such as plants, animals, land, air, water, mountains, oceans, stars, etc.) that is not made by people.     And the word nature refers to the interaction between the physical world and the life within it. Now I want you to close your eyes and imagine that you are outside, anywhere you want. You can be at the beach, wood, mountain, or you can simply be in a garden. now, what do you see in your imagination? Everything we see, eat, touch, hear, or feel comes from nature. Life of nature Nature keeps changing form season to season, from minute to minute. The nature has not always looked the way it looks today. In other words, the carrot one billion years ago was in a totally different shape than it is today!! There is another proof, so why is Greenland called Greenland if it is icy? Back then, thousand years ago, green land is greener.    But nature is keep chang...

  The world has change and it means to be ready to succeed in the future has also change. That means our model of learning must change. Like remodeling a house, we have to strengthening what works and fixing what doesn’t. that is why we need a new way of teaching and learning. For example, we can use student centered learning model. What is student centered learning? Is an instructional approach that places focus on the students, instead of the teacher. Its missions is to create independent and responsible learners for the feature. SCL is a modern way of teaching where the role of the students is deemed to be very critical in constructing their own understanding from new information and prior experiences. Why is student centered learning? There are many positive benefits that using a student centered learning model. Research has shown that students learn how express themselves and articulate their individual ideas. This learning environment allows students to be more engage...
