In a time, when nuclear energy and research are used for wheeling and dealing and each reactor breakdown leads to global panic, the scientific knowledge is necessary for all of us. As a physicist, I want to tell about this phenomenon and rebut some myths. (http://lcnp.org/images/nuclearpower.jpg) 1. The nuclear power plants are radiating. People living near are at risk of irradiation. All radiation created in reactor is held inside lead screens and concrete walls. Any type of radiation is able to penetrate these heavy shields. The only way for radioactive materials to get out is destruction of building. This is what mass-media are afraid for, forgetting that there were only two breakdowns in history: Chernobyl and Fukushima. Only two for 435 reactors on our planet. One of them was caused by failed experiment (meant to produce fuel for atomic bombs), and second by an earthquake. Without a serious cause, there is no chance for radiation to get out from nuclear power plant. 2. G

Wikipedia says that " Dance   is a type of   art   that generally refers to   movement   of the body, usually rhythmic and to   music,   performed in many different cultures and used as a form of   expression,   social   interaction   or presented in a   spiritual   or   performance   setting". (source: http://en.wikipedia.org/wiki/Dance ) Dance was discovered at the early stage of hominid evolution. Its styles have evolved and now we are dancing completely different that our ancestors were. But one thing doesn’t change – we use dance to express not only themselves but also the traditions and culture. Flamenco. Is a dance – but also o music – from Andalusia in Spain. It derives from old religious  oriental dances and is connected with three cultures which appeared in Iberian peninsula: Gypsy, Indian and Spanish. There are many types of flamenco, but the main features are emotional intensity, proud carriage, expressive use of the arms and rhythmic stamping of the f

Very few people bother to think what they really eat. This a great mistake, because food plays important role in our life. Only need to mention that e ating healthy helps to improve concentration and thinking, which result better grades at studies:) Many of us when hear about proper eating thinks  immediately   about low-calorie diet or  nutritional labels on packed food . However, e qually important   is to  be concerned about ingredients of   which   meal  is made. This we should do especially nowadays , when we can't check directly in what conditions  are grown  for example vegetables . In this post i will present  new types of food which you can find in  the shops. 1. Organic Food EU organic food logo Organic food is food grown through a process of farming without chemical pesticides and without artificial fertilizers. It is food grown in soil that is alive with billions of micro-organisms that convert the remains of vegetable l

GLOBAL WARMING Reposted from: http://oczyszerokozamkniete.files.wordpress.com/2009/12/gw.jpg , 16.05.2012 . Recently we hear a lot about global warming. Radio, press and television have recently moved the salable topic. But what , it really is global warming and whether they are really devastating consequences ? What is global warming?   Global warming - the phenomenon of increase in the average temperature of Earth's atmosphere and oceans. Since 20th century average surface temperature has increased by about 0.8 °C.   Global warming is caused by the discharge to atmosphere of greenhouse gases - mainly carbon dioxide and methane. In other words , instead of heat to escape into space, it is accumulated in the atmosphere like in a thick blanket , causing the temperature increase .   Reposted from: http://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Greenhouse_Effect.svg/750px-Greenhouse_Effect.svg.png 16.05.201

I was stuck in a traffic jam .....again!!! 20 minutes in traffic? One hour in a traffic? Half a day in a traffic? Annoying journey to school, work and from school or work? Constant traffic jams and clogged crossroads ... in a big city that situation is the norm during rush hours. Congested urban streets it's not happy and very frustrating everyday life for many of their inhabitants. Some metropolitan areas cope better with this problem, some worse. What causes traffic jams? What is their impact on our health? Prevent them or learn to live with it? I'll try to answer these few questions. The causes of traffic jams Causes of traffic jams are obvious to most people. A huge increase in the number of cars and a small amount of new roads( especially in Poland)- is the main reason. There are also quite immediate the causes of traffic jams, such as stenosis, repair of roads, accidents, etc.. According to researchers, there are three theories

How can we spent time in traffic jam? Traffic jams are the woes of a fast and speedy lifestyle with more and more people relying on their personal transport, there is an extremely high number of cars on the streets and this rush os only set to increase. Traffic jams always make us all a little bit crazy, even if we do not want to happen.  We all go through classic felling of anxiety, anger and rage, don't worry it is normal behavior. But we have a lo of better ways to spend your time while stuck in traffic, it could be  based on some sort of positive thought process.We must find ways to use the time productively.:) 1)KEEP SOME READING MATERIAL HANDY: You must keep some newspapers or books with you in the car. If you are very busy and don't have time to ready books, magazines, you can have chance to do it when you stuck in traffic jam, this is a good way to kill time,relaxing, forgetting about the situation in which you found and catching up on your reading.:)

E veryday we use natural resources of the Earth. We breathe, take a shower, walk, sunbathe, refuel. Are we aware of it? Are we aware that some of this resources end in the future? On the Earth we have a lot of resources, which we don’t know or we don’t think that we can use them in other way than normal. I will try to show you how we can use some of them. Water This is one of the most important resources on the Earth. Usually we use it to drink. But remember that, unfortunately, not everyone has an access to clear drinking water. According to research, above 2 million people(especially children) died, because of the lack of drinking water. Thanks to the water we can create an energy by building hydro-electric power station. http://pl.wikipedia.org/wiki/Elektrownia_wodna Water – power station in South America. How does it work in real? Have a look - http://www.youtube.com/watch?v=mB_J0EW-4-k Water can be so helpful for us. Not only by drinking everyday, but also i
