Humans have harnessed fire, created and tamed electricity, and invented antibiotics… the list of human achievements is seemingly infinite. Each discovery of this magnitude changes the usual course of things, without a doubt, and is a step toward a better future. The same is expected of nanotechnology – a young science that studies objects on the atomic scale. It all started with a single lecture.
OYLA, the kids magazine, is a unique periodical filled with knowledge and information useful to kids like me.Every topic is discussed with clarity and focus, giving importancs to its origin and development. It has not ignored the little toothbrush to the game of tic-tac-toe-explaining its history and usage.That the contents come closer to my curriculum, helps me relate to subjects of my study. While the pictorial representation and description is an added advantage, the quality of the pictures cannot be left unappreciated. On the whole, Oyla, page to page is wrapped with facts and intelligence. I genuinely take this opportunity to appreciate their legitimate hardwork and efforts in preparing the magazine for young readers like me. Wish you many more years of knowledge sharing.
I like OYLA so much; it gives me knowledge, fun and sometimes I have seen funny pictures. In OYLA I like the May issue(#5) as it came during summer holidays.I got interested when I saw the topics " How about a coffee" and " A cup of Coffee" in the table of content. So far, I thought coffee was a bush, but it is a tree. I was so surprised to read that the most expensive coffee was made from coffee bean found in an animals excrement. People of Finland drank a little too much of coffee while Canadians drank coffee least in the top 10 countries; but India does not even show up in the list. OYLA advised me not to drink an espresso because it is bitter. Cappuccino is what I drink but it is a littlt different; it is made of milk and had foam, sometimes they draw on the foam. And there are a lot more that I never knew. In another article. I learned that Japanese cant pronounce "L" or evenanything that starts with the letter "L". I used to watch anime, and it is real that Japanese dogs do bark "Kian-Kian". And in anime, OYLA says, that they speak perfect Japanese. It is not real! The voice actors speak like they are half- Japanese.
Each issue of OYLA has a load of fascinating topics that attract readers of all ages. Topics explained in simple language and the concepts are easier to grasp. Able to gather lot of information from each topic of very few pages. Each topic is discussed in different perspectives and the coverage is superb. Helps to get the glimpse of topics that are unknown to me and they are starting points for further exploration. Best science magazine ever read. makes me eagerly waiting for the next issue.
Let us consider a circle and a point that does not belong to it. Connect all points of a circle with the given point by line segments and draw perpendicular lines through their midpoints. These straight lines will fi ll a part of the plane as if bending round the untouched areas. In the case when the selected point lies inside the circle, the envelope boundary will be an ellipse, and if the point is outside the circle — a hyperbola. A similar operation can be performed with a straight line and a point that lies outside it. In this case, the boundary will be a parabola.
MoreIn Dan Browns novel Angels and Demons, villains steal a gram of antimatter from CERN and threaten to blow up Rome. Now we know that when a substance meets antimatter, both masses disappear, turning into radiation strictly according to Einstein's formula: E = mc2. As you can see, there is a monstrous magnitude in this formula — 300,000,000 meters per second, which is the speed of light, squared. This makes antimatter much more powerful than a thermonuclear bomb. Calculations show that the annihilation of that stolen gram of antimatter would be equivalent to 430 kilotons of TNT!
MoreThe brighter — the warmer? Life experience tells us that these two concepts are inseparable. however, the laws of chemistry refute this interdependence: matter can glow “cold,” with no heating at all. And what is most surprising — such phenomena occur literally everywhere. To illuminate a room, you can switch on a light bulb, but if you are in a dark grove, you will have to build a fire. The bigger the fire, the more light there is. You can also warm yourself up if the night is cold. In the morning, a natural light source will be back — the sun, heated up to 6000 K, giving Fluorite crystals can glow when heated — the process of thermoluminescence. Fluorite is a typical fluorescent mineral, but when it is warmed up or irradiated with ultraviolet light, it starts to phosphoresce. For matter to fl uoresce, an electron in its atom must reduce its energy, that is, move to a lower energy level, emitting the excess energy as a particle of light, a photon. But first, the electron absorbs energy and gets into an excited state. It stays there for a while and, at an arbitrary moment, jumps down, emitting a photon. There are many electrons, so photons are emitted almost at all times, and the substance glows continuously and gradually dies away while the number of excited electrons decreases.
MoreThe heart is an essential organ of the human body. Scientists say that with age, the heart increases in size directly proportionally to the growth of a persons own fist. Ancient people thought that the heart was the chief organ which controlled the whole body and so people used to believe everything related to the human condition and relationships was connected with the heart. Now, of course, we understand that this is the work of the brain. Certain expressions emerged, such as “stout-hearted,” “a warm-hearted person,” and “I love you with all my heart,” though it would be more accurate to say “I love you with all my brain.”

Superconductivity is a phenomenon that has shaken up the scientific community on numerous occasions throughout the 20th century-even bringing different researchers Nobel Prizes on seven separate occasions. Thanks to these studies, we have high-speed bullet trains, tomography, supercomputers, and the Large Hadron Collider. Furthermore, in New York in 2008, the first superconducting power line in the world was established. Its capacity is 10 times greater than that of conventional copper conductors. So what is special about this phenomenon, and what causes superconductivity?

The concepts of acid and base are introduced to students in school. These substances find use in daily life. Substances like tamarind, vinegar, lemon and other citrus fruits are acidic in nature and are sour to taste. Similarly bases are bitter in taste.
