19-year-old Student Preparing Georgian Pupils for International Young Physicists’ Tournament

17554720_1417909054942741_2046776670_n

V. Komarovi Tbilisi physics and mathematics N 199 public school has actively been preparing for the International Young Physicists’ Tournament (IYPT) for several months.

It should be noted that 19-year-old student Giorgi Tsereteli trains the Georgian school students for the responsible tournament.

The young physicist spoke about his activities in his interview with “Doctrina”.

Currently, Giorgi is a second-year student of the department of physics at Free University of Tbilisi. He showed a great interest in physics at an early age and has won a lot of prizes. For example : when he was a twelfth grade pupil, he became a member of the Georgian Olympic Team in Physics. Due to this fact Giorgi was enrolled in the University without requiring to take exams.  Since that time the young physicist has actively been participating in various conferences. Giorgi Tsereteli participated in Kakha Bendukidze Annual Conference on Physics this year and together with several other students he will participate in the International Conference of Physics Students that takes place in Turin, Italy on August 7-14.

Due to their experience in this field Giorgi and his friends have won a national tournament, too. Komarovi physics and mathematics N 199 public school asked Giorgi to lead the laboratory team. “It is incredibly pleased when I see how much progress our children make. The school has a relatively new and high-tech lab and together with the school students we are establishing much more interesting and diverse approach towards physics problems,” – Giorgi said.

This year tournament takes place in Singapore in mid-June and five participants, one trainer and one member of the international committee are taking part in it. However, the team has not been composed yet.

Giorgi Tsereteli and the pupils have solved a lot of physics problems. For example: if you pour honey or any other sticky liquid (for example, shampoo) from height, it makes coils (see : picture I). The pupils were tasked to learn the reason of this process. In addition, the pupils are currently working on the device giving the visualization of air density (see: picture II). It should be emphasized that the greatest problem the young students facing in this field, including technical or financing problems, goes beyond their capabilities.

“Very often there is the problem related to funding of the team participating in the national or international tournaments. Sometimes, schools provide us with funding, sometime we are funded by the City Hall or universities, however, I cannot say that the situation is stable. In addition, there is not a great number of schools willing to participate in the scientific tournament, despite the fact that any 15-year-old child is able to participate in it,” – Giorgi Tsereteli said.

“Mecnieri.me” – Georgian Student’s Project Aims at Improving Children’ Cognition

Tako basishvili

“Mecnieri.me” ( scientist me ) is another new project that aims to create scientific experiments for kids and teenagers. These low-budget experiments are easy to conduct at home. The experiments help teens deepen their knowledge in the fields such as astronomy, geology, meteorology, computer science, physics, mathematics and engineering.

“Doctrina” has interviewed project author – Tako Basiashvili.

Tako Basiashvili, who is just 19 years old, is a second-year student of the department of  biochemistry at the San Diego State University. She has already participated in the implementation of the very responsible and interesting project.

The project – “Mecnieri.me”  is a cognitive online portal for children aged under 12 years of age. There are interesting and simple experiments placed into the portal. The main charm of these experiments is that each of them can be done by the supplies that are easily available at home.


In order to better understand the project, let’s take one of these simple experiments : “invisible ink”. This experiment requires only a sheet and lemon juice. If a child writes any word on a piece of paper with a lemon juice and then dries it nothing will appear on the paper, but in case of reheat it the written word will clearly be seen. The process is not only fun, but also cognitive, because children are able to find the process explanation on the site and to understand more about it. The website provides them with relevant information about the process.

Thus, they learn that the lemon juice, as well as other fruit juice, contains carbon compounds. These substances are invisible at room temperature, but in the heat they may dissolve and release the carbon. In case carbon meets air, oxidation process begins and the substance turns into open or dark brown colored substance, which is the experiment’s result.

The following simple experiment is ,,giant soap bubbles “.  Probably every child dreamed of having large soap balloons, which actually is not as difficult as it seems. In order to achieve our goal, we need to mix one cup of water with two tablespoons of dish washing liquid, a tablespoon of glycerin (available in pharmacies) and a teaspoon of sugar, the mixture should be kept in a closed container for 1-hour period, and then, we have to mix gently and start forming giant bubbles with flexible metallic sticks.

“Studying science and technology at an early age will support violation of stereotypes about these fields in our country and it will be the guarantee of future growth and success of the fields of science and technology, “- Tako Basiashvili said in her interview with “Doctrina”.

Young Georgians’ Invention –  Device that Predicts Landslide

17454960_1323708924376675_1993876362_o

“Smart Kids”, the team of Georgian school students, was named a winner of the Millennium Innovations Award – MIA competition on February 27 of the current year.

The team members: Alexi Tkebuchava, Natia Shamatava, Dea Chitaia, Lika Kokaia and Gvantsa Chikovani are the students at St.Aleksi Shushania’s school-gymnasium in Senaki district of Samegrelo region of Georgia.

The competition aims to encourage young people in STEM fields. It will promote the development of these fields in the country. In April, the team will travel to the US NASA space center.

“Doctrina” has interviewed the team members as well as their mentor Uta Kilasonia.

“Our project – ,,geologic hazards”, aims to predict  danger of a landslide. This device is a notification system. We have used the Hall sensor, which shows the changes in magnetic field strength. Our project has many advantages: it’s cheaper, it’s suitable for all kinds of terrain, it’s accurate and reliable one. The most important thing is that it can be produced and introduced in Georgia. Magnets are placed on the ground, in a small ditch, Hall sensors are placed above the magnets, few millimeters away from them. The magnets are connected to a micro -processor and information is transferred to the central server by using the GSM System. An app that enables us to regulate the ground vibration limits, is loaded in tablets. When the ground vibration exceeds the limit, the device automatically sends messages to the mobile phones of registered population. It should be noted that the sensor device has no analogues in the world. This idea came to us due to the 2016 disaster in Senaki, the August flood and mudflow affected the district, in particular, the access road and the bridge of our school-gymnasium was collapsed”- the students said.

“We have studied the current equipment that cost millions of Gels. We think, that our device is cost-effective for the state. It costs just about GEL 10 000, and is more accurate than the existing ones, “- Uta Kilasonia, the team mentor, said.

The device is scheduled to be installed on the territory of Nokalakevi Protected Area and Archeological Museum.

It should be noted that the sensor device, created by the young Georgian school students from Senaki district, has a great response and positive assessments from the scientific community.

The young inventors will travel to NASA to undergo the educational program of the University of Space Center.

Smart Wooden Ring by Georgian Students Makes Life Easier and Safer

კნიკი

Georgian students have developed a smart wooden ring that can make people’s life easier and safer.

“The idea came to us at our University. Campus has a system of permits. We wanted something that would replace the identity card for allowing us to enter the building. Thus, we created the first ring and its first function was about entering the hall,” – Nino Gvazava, one of the authors of the invention, has said.

The students melted different cards, placed the RFID tags into the 3D printed ring and then, using it made payments at various stores.

,,Cnick“ is a smart ring that is made of ecologically pure wood and enables customers to choose own rings’ design, the inscription on it and the relevant colors. In addition, it is the only ring that substitutes a user’s wallet and cares for the life of the owner at the same time.

#CNICK is the first smart ring that unifies a pass, a debit card and a seasonal ticket and enables users to enter various organizations and offices, including sports halls, cinemas, entertainment centers, with only one gesture, at the same time, the ring saves the medical information about the person – blood type, past illnesses, allergic responsiveness etc. This is very important and it means the Cnick can save a person’s life.

The startup ,,Cnick” participated in the international investment conference Seed Forum 2016 which was held on December 14 at the center for innovation and entrepreneurship (iHUB) with the support of the Norwegian Ministry of Foreign Affairs.

Within the frameworks of the project the founders will be able to undergo trainings in Oslo, Norway in May and to introduce their idea to investors in order to obtain additional funding for improvement of the project and to make new connections.

Currently,,,Cnick” has not a payment function as it is required to undergo various certification processes with Visa and Mastercard  for mass production of the ring and it’s a matter of time. The startup is actively involved in this process and the ring will soon offer the function of payment.

Gaming Vest with Sense of Reality – Georgian Young Inventors’ Successful Project

ჟილეტი

Laser Combat — is the waistcoat, developed by three Georgian young students, enabling gamers to perceive games as real. 

“Doctrina” has interviewed Givi Beridze, one of the authors of the idea, who gave some details about the project.

Givi Beridze, Nikoloz Sikharulidze, Tornike Patskhashvili, students of faculty of computer science and mathematics, and Irakli Mskhiladze, a student of electrical engineering at the Agrarian University, are the authors of the project.

Childhood memories, when there was no feeling of reality during various games, have inspired the idea of creating the waistcoat. The Georgian students have decided to develop a vest, called Laser Combat, which gives gamers a sence of reality and at the same time, is safe and painless.

Laser Combat is fully equipped with sensors and when a laser beam falls on a sensor, the vibration engine is activated behind it and gamers have an impression that the bullet really hits them. It should be noted that this technology is extremely similar to the existing ordinary vests, but the feeling of realism distinguishes it from its rivals, such as – “Airsoft Paintball” and etc.

Apart from winning the “Innovation Camp”, Dubai investment companies “TURN8“ and  “I360 accelerator” imposed a monthly grant and in this way assisted the winning team in implementing the project.

Young inventors presented their idea to the “Start-up Georgia”, a government-initiated innovative business supporting program, and took the fifth place out of total 20 participant projects. Many investors liked the idea. The project has received Gel 100 000 in investment and the authors could market their product.

The young students hold negotiations in Georgia in order to open the first gaming club. They also plan to enter the European market.

Young Georgians’ Invention Helps Patients in Rehabilitation Process after Stroke

jj

A Glove declared a winning project at the Makeathon competition – “Your Start-up Idea in Reality” – held in November, 2016.  The Glove helps the patients, who have had a stroke, in rehabilitation process.

The authors of the project are two young brothers – Giorgi and Dimitri Tskhovrebadzes. 19 year old Dimitri Tskhovrebadze is a student of the department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), as for the younger brother, Giorgi, who is going to turn 18 soon, he is a student of school of Mathematics and Computer Sciences (MACs) at the Free University, Tbilisi, Georgia.

Mr. Giorgi Tskhovrebadze has told “Doctrina” that the new Glove idea was generated just when the Makeathon competition was taking place at the Ilia State University of Georgia (Iliauni).  Then the brothers elaborated the idea, which was approved by the jury.

The new device is designed for people who need stroke rehabilitation. According to statistics, 15 million people suffer stroke worldwide each year. Generally, people who have stroke lose their ability move. It takes several months to restore the moving ability, and the treatment process requires huge financial resources (more than USD 10,000).  The cost of the Glove, developed by the Georgian inventors, does not exceed USD 150.

How does the new Glove work? – A patient puts a glove on her/his damage hand and performs funny, simulation-based tasks. Sensors perceive the movement and tries to make the Glove to perform the same action, as a result, the Glove helps the damaged hand repeating the same movement.  Finally, the patient moves both hands in the same way, while brain starts restoring functionality and the movement ability is improved.

The winners attended the world congress of mobile technologies held in Spain in February of 2017.  They were fully funded.  ‘We have just been named among the ten best teams at the “Jacobs International Startup Competition” and in late March we’ll present our project in Germany, where a final stage of the competition is due to take place,” –  Giorgi Tskhovrebadze said in his interview with “Doctrina”.

So far, the prototype of the glove is being manufactured.  Afterwards, the device will be used in the treatment process and will undergo a special observation at the various hospitals.

What is Time?

გია დვალი

There is no unambiguous answer to this question, but there is a lot of speculation. Do we need time to feel and describe reality? Is time travel possible?

“Time is the parameter for describing the reality. People perceive themselves in space and time, therefore, our sense organs perceive the three spatial dimensions: length, width and height. However, according to some suggestions, there is the fourth dimension [of space] and it is time,” – famous Georgian physicist Gia Dvali has said. Currently, he is a professor of theoretical physics at New-York University and Ludwig-Maximilians-Universität in Munich, he is also the Director at Max Planck Institute of Physics and the CERN (the European Organization for Nuclear Research) scientist.

One of the founders of classical physics, Isaac Newton considered that there was no connection between space and time and generally, space is absolute. According to Newton’s law, time is invariable and flows equably without relation to anything external. Newton’s view on time and space is opposed by Albert Einstein’s theory of relativity, saying space has three dimensions, and the fourth dimension is time. This system of ideas has changed the fundamental views of the classical physics on space and time and their ties with the matter.

Physicist Gia Dvali notes that there is acceleration or deceleration of relative time – what does this mean? for example, the well-known “twin paradox”, one of whom makes a journey into space in a high-speed rocket (close to the speed of light, which is approximately 300 000 km /s), when he returns home he finds out that the twin who remained on Earth has aged more. It happened because of the time dilation, it’s an ordinary physical effect, which has been verified experimentally.

Deceleration and acceleration in different parts of the space occur due to gravity. If we come close to the black hole, our biological clock will slow down, because the area of the gravitational field is very strong. Scientists say the nuclear fuel can be exhausted in the solar core and everything can be absorbed due to the gravity. People have long been asking: is it possible to travel through time? As it was mentioned in the example of the twin paradox, it turns out that the theory of relativity makes possibility of time travel to the future. As for the travel to the past, many scientists believe that this is impossible. There will be the cause and effect problem here, for example, they are talking about the “grandfather paradox,” it is a paradox of time travel in which inconsistencies emerge through changing the past. The name comes from the paradox’s common description as a person who travels to the past and kills his/her own grandfather, preventing the existence of his/her father and therefore his/her own existence. British physicist Stephen Hawking has said that the fundamental laws of the nature rule out possibility of such travel. Georgian physicist Gia Dvali says : “I can sit in the spacecraft,  travel at light speed, then return back and I’ll appear in the far future because my biological clock runs more slowly and a thousand years pass on the earth. But I cannot come back. As for the travel to the past, I can tell you that it is impossible, because it does not gives us the self-coherence, by traveling to the past, you could change the present, while the nature does not like paradoxes.”

It should be noted that each individual perceive the flow of time differently. It flows slowly or quickly. Time perception depends on various factors, for example: psychological development, health condition, temperament, metabolism, age. Apart from a lot of theories and experiments, it is believed that time only exists in the human mind and does not exist independently. Humans have the demand of measuring time in general. That is why they have developed various time measuring devices, including the water, sun, sand, digital and mechanical clocks. The fact is that it is possible to measure the time and humans need it to establish order.

“Georgian as a Foreign Language” – E-learning Effectiveness

კომპიუტერებთან სწავლება

The programme on “Teaching Georgian as a Foreign Language”  is being developed at the Ministry of Education and Science of Georgia. The teaching and methodological e-materials which are developed within the program, provide a full package of teaching and learning the Georgian as a foreign language for students and teachers. The program is being implemented in cooperation with the Language Policy Division of the Council of Europe (LPD) and in accordance with the general European linguistic competence.

Scientific portal “Doctrina” has interviewed Marika Odzeli, the author and the head of the programme.

 

-There are a lot of analogical programmes in the various countries of the world, but it’s unprecedented one in Georgia. How the idea came up and what triggered the development of a platform in our country?

Several years ago we developed the European Language Portfolio (ELP), which includes linguistic competence, both in native and foreign languages. Primarily, it was intended for ethnic minorities living in Georgia who were interested in learning the Georgian language. Later, in 2012, the fragments, methods or approaches, offered by the program, encouraged the first standard of the “Georgian as a Foreign Language”.   Until 2012 there was neither level nor frequency based vocabulary in Georgia, respectively, the program is still in development and we are making attempts to improve it.

 

-As for the methodology, how the teaching process is being implemented?

– Based on the program’s German and French analogies we have elaborated the first textbook for the methods of teaching the Georgian as a foreign language. Afterwards, we decided to elaborate textbooks based on language levels. It should be noted that until that time there was not a monolingual textbook of the Georgian language for foreigners, therefore it must be stressed that it is not designed for self-study, but for individual or group trainings. There is the textbook “Aghmarti” as well as a relevant workbook, the material includes writing and listening tasks. The natural and lively dialogues, together with relevant instructions, allow the interested person to easily understand the basic specification of the language.

 

–  What about the statistics of the countries, which use the program and actively cooperate with you?

-Nowadays there are bachelor’s degree courses in Georgian language and literature in several cities of Turkey and there are two generations of the graduated students. 20 students are enrolled into each course, though we hope that the number will rise in the future.  Last year on the initiative of the Education Ministry the Turkish students visited Georgia for one week and we tried to familiarize them with the Georgian culture. The program is successfully used in Petersburg, where there are special courses in the Georgian language.  It should be noted that in order the learning process to become easier for their students, the above-mentioned countries try to adapt the program and make some modification in agreement with us.

Brazil, China, Iran, Russia are among the countries which use our program, but according to the statistics, the users living in Georgia are dominated.

 

-Whether the program has any restrictions or not and who has an access to it?

-The program is available to all individuals who visit our site geofl.ge, after visiting the site they will have free access to the online textbooks and other materials. They can also put us any questions and make comments.

 

-What was the global response to the program on Teaching Georgian as a foreign language?

-It is very important that we are contacted from different countries; they give us thanks for services rendered by us. Some of them have even published their reviews about us on their own will. One of them is Yasuhiro Kojima. Here is the quote from his review: “Internet books will be available for everyone around the world and this will be a unique opportunity for them to study Georgian language. The series will particularly be useful for Georgian children living abroad and more, I would like to use these books to my son in Japan as well.” (It is notable, that Mr. Yasuhiro Kojima’s spouse is a Georgian woman).

 

– Are there any planned changes regarding the program in the nearest future and

how are you working on the program development?

-Now, we think to develop a bilingual dictionary within the frameworks of the program. Simultaneously, we are improving the existing levels (A1-A2, B1-B2) and after that we’ll start working on the C-level appropriate materials.

Route Maps for Tourists to be Placed at Tbilisi Metro

სატრანსპორტო

Subway route maps will be placed at Tbilisi metro stations in the nearest days.

The project, which is initiated by the Tbilisi Transport Company and  the “Urban Laboratory“ organization, aims to offer more comfort to the citizens of Georgia as well as to the foreign visitors.

The bilingual maps contain route schemes and the capital’s sights, allowing passengers to easily plan their travel.

The competition for the maps’ design was announced few months ago.  Designers from the various countries participated in the contest, which was held in two stages. Young designer Iana Shavganchuk has been selected by the jury under the criteria, agreed with the Tbilisi City Hall and the Tbilisi Transport Company.  His work is notable for the synthesis of the capital’s sites and the subway route scheme.

Merab Mamulashvili, deputy head of the Transport Municipality Service, told media representatives that the maps would help not only foreigners, but also the citizens of Georgia, arrived in the capital from various regions of the country.

The project is financially supported by the NGO “Orbeliani” and the Swedish government.
