1. How did life originate?
For 80 years now we are told that the first self-replicating molecules appeared in the primordial soup in the Earth’s shallow waters, which happened 4 billion years ago. This “soup” was composed of amino-acids, polypeptides, and nitrogenous bases of nucleotides formed as a result of electrical charges, high heat and cosmic radiation.
However, the experiments to replicate similar processes have given mixed results: the basic monomers began to form substances that prevented the expected complexity to exist in this “soup” of polymers.
Later, the problem seemed to have been simplified by the “RNA world” hypothesis, but the probability of spontaneous formation of RNA, which would Continue reading
Over the last decade great attention to the functioning of the cerebral hemispheres and its effects on the process of learning was paid. This interest has to do with the fact that traditional teaching models are based on the functioning of the left hemisphere i.e. the development of language and logic, without taking into account the characteristics of the right hemisphere, such as intuition, spontaneity, and imagination.
Although the famous French mathematician Poincare argued that “the logic proves but the intuition creates” and although the Hungarian scientist Michael Polanyi talked about mental beauty and passion in the process of knowledge discovery, only recently science began to recognize the role of Continue reading
Intelligence emerged as a result of a genetic accident – this is the most common conclusion among researchers who study human evolution. Their studies would also have to answer why the brain remains, in spite of all the important tasks it performs, a sleeping giant since neurological research shows that we only use 5-7% of its potential.
Human intelligence is the result of a huge number of interconnected neural functions, producing manual dexterity, a highly sophisticated and clear stereoscopic vision, recognition and use of complex symbols (abstract thinking) and a very long memory. Nowadays, the predominant scientific view is that there are many degrees of complexity intelligence (some of which are present in all mammals) and that humans share with apes and dolphins a lot of characteristics that, until recently, were considered unique to human beings.

Learning of a second foreign language is particularly beneficial not only for one’s curriculum but also for the brain, according to a new scientific research, which comes to confirm previous studies claiming that knowledge of foreign languages is a beneficial form of education of the brain, which enhances concentration, attention, memory, etc.
Researchers from the Northwestern University of Illinois, who published the study in the journal of the National Academy of Sciences (PNAS), concluded that bilingualism affects the brain and fundamentally alters the way the nervous system reacts to sounds, as shown by the laboratory experiments.

Before you start reading this text, look carefully at the keyboard of the computer you are using right now. Pay more attention to the left side, just under the key “1”. These first letters of the keyboard from left to right: Q, W, E, R, T, and Y have given name to the so-called “Qwerty effect”.
British and American scientists found out that people prefer words consisting of letters located at the right side of the keyboard than at the left one. It has to do with the Continue reading
Today there are many ways to learn a foreign language quickly. Here are the most effective ones.
The easiest and fastest way to learn a foreign language is to learn it in its natural environment. Everyday situational communication in a foreign language in all spheres of life is a guarantee that within a year you’ll be fluent in spoken language. So use every opportunity to go abroad at least for a little time on study or across multiple programs of experience exchange.
Today the most common way of learning a foreign language is to follow language courses or take individual lessons with a private tutor. Which method is more convenient and effective?read more
LanguageTool is an Open Source language checker for English and German language.
This is a rule-based language checker that will find errors for which a rule is defined in its XML configuration files. Rules for more complicated errors can be written in Java.
You can think of LanguageTool as a tool to detect errors that a simple spell checker cannot detect, e.g. mixing up there/their, no/now etc. It can also detect a limited amount of grammar mistakes. It does not include spell checking.
First of all, it depends on your native language and foreign languages you know. For example, if you know Latin, it is easier to learn languages of the Romance group. If you know French Spanish will seem easy. However, there are ways to estimate a Continue reading
Which language to learn today to benefit in future and make a successful career? Professors of leading educational institutions believe that in the next 10 years the most useful languages in international business will be English, Spanish, Chinese and Arabic.
English is easy and logical – it’s clear. Today it dominates thanks to a big role of Internet. As a global language English strongly intrudes into all the national languages by means of mass communication. This situation is not going to change in the next years as far as English remains Continue reading
