In an interview, Prof. Dan Shechtman, the recent Nobel laureate, expanded on his teaching in the field of education: "The State of Israel needs to invest a lot of its wisdom and money from kindergarten, through elementary school to high school" and also reveals how he helps high school students get to know science through the posters of the Nobel Prizes in the decade the last
The field of crystallography has now gained momentum thanks to the Nobel Prize awarded to Prof. Dan Shechtman of the Technion, however, in an interview with the Hidan website, Prof. Shechtman says that although he made the initial discovery, in order to provide a physical and mathematical explanation for it, he needed the partners who helped him convince the scientific community: "He needed the This recognition, the Nobel Prize is the ultimate recognition for any science, but I am a spearhead and on my side There are thousands of scientists who are working on this subject. Thousands of people have worked and are working on it. In particular, I would like to mention several people to whom I am sorry that they are not partners with me: Ilan Belch, who wrote the first paper with me and in which the physical explanation was laid out John Kahan and Denis Gratias who published the first article with me - just a little anecdote, the article with Blach was sent first but the second article was published before it because it The magazine was informed that the processes there are faster."
In all the interviews given by Prof. Schechtman since the announcement of the winning discovery, he has focused on the crisis in education. Today's education system hardly educates for excellence, and he also has something to say about the part of the media that ignores science and hides this possibility from teenagers who are in the process of searching for their future.
"The State of Israel needs to invest a lot of its wisdom and money from kindergarten, through elementary to high school. We need to prepare our candidates well for university. This is the main role of the education system in Israel. What is our future without an excellent education? I don't understand security and health, I do understand science We need to invest a lot of resources and wisdom, it's not a political matter, it's a matter for all of us." Prof. Shechtman said.
"As I said on television, in order to raise a generation of scientists, you have to start in kindergarten. We need good teachers from kindergarten through elementary school, through middle school and up to high school so that the universities will have many good and ready students. We are producing great engineers, look at Israeli high-tech But to get there, the engineers of tomorrow have to go through the entire educational chain In certain periods of time, science was revered by everyone - one is the media, mainly television, and the other is the education system."
What is the role of the teacher?
"The role of a teacher is first of all to be a role model. The behavior of the teacher in the classroom tells the students in a non-verbal language how a person behaves. If they come from a home where the behavior is not what we would like to see in public, then the school has to correct it by A personal example. I have not yet talked about what should be taught to the children, but what personal example should be given to the students, so the teachers should be chosen in such a way that they will serve as role models. Why not Because the salary that is paid to teachers is such that many people who could be teachers cannot afford it even if they want to be teachers because it is impossible to support a family with such a salary. This is one of the roots of the problem. We need teachers who know how to act as role models , who change the bad behavior at home and know how to act as leaders in their class. Then they will come to the Technion and other wonderful universities in Israel - Weizmann, Hebrew, Tel Aviv, Bar Ilan - people who are cultured, who have a background in mathematics, physics, chemistry, English and biology to become the scientists of the future and those who, after completing their first, second and third degrees, will become top scientists."
Teachers don't know how to deal with wild classes
"Already today, top scientists are coming out, but without proper preparation, the flow will dwindle. I had good principals and teachers at my school (I think there were more male teachers than female teachers, and today that doesn't happen anymore. I don't think a female teacher is any less good than a male teacher, but the fact that there are almost no teachers is simply due to From the difficult conditions a teacher has to deal with and of course from the salary conditions, the teacher is also expected to deal with the classroom where discipline is a difficult problem The teacher has to deal with wild classes because if he doesn't know how to deal with it, he can't teach and can't serve as an example."
"I believe that the teachers know the material, but we need to create a situation where they can pass it on to the students and we need to bring in good people to teach and we need to start very early. Children need to start reading in kindergarten and reading books because many children don't read books at home, with us the thing that takes up the most space at home are the books But there are houses that the children do not read.
How surprised were you by winning?
"I was completely surprised. First of all, I did not know that this was the day when the Nobel Prize in Chemistry is announced. I never know, and I was not told. They talked to me about yesterday and consoled me that I did not win the Nobel Prize in Physics. In the end, I won in chemistry - this field falls between The two, it belongs to chemistry as it belongs to physics. To be honest, I thought I wouldn't get the Nobel Prize because it's been many years and I'm living very well without a prize Noble, I may live less well now."
How do you intend to use your status as a Nobel laureate on the public stage?
"I am a Zionist and the State of Israel is very important to me, the success of the State of Israel is a personal success. I am the grandson of the people of the second aliyah, my grandparents are from the 10% who stayed in Israel and did not emigrate. My grandfather, Zeev Ashur, was one of the founders of the labor movement in Israel. The group that included Ben-Zvi, Ben-Gurion, Rachel Yanait, Zerubbabel and others. My grandparents are among the founders of the State of Israel and I owe them a great debt, I am here and I feel it that I must contribute to our heritage."
"Everything I do is for the State of Israel and voluntarily. Every year I send the posters of the Nobel Prize Committee that explain in simple language the essence of the prize to 600 high schools, I translate them. More than 10 years ago I called the prize committee, I spoke With the Swedes and I said - you publish such a great poster in Swedish and English, you allow me to translate it into Hebrew to distribute it to high schools to promote science In Israel? They told me: "No, we will do it for you". They send me the original in English and I correct the Hebrew (after all, there are things that need to be changed from language to language). I send the file to Sweden. After that, I have a direct contact with a graphic artist who works with the prize committee. He builds and sends me the file. I had a hard time with him at first because he didn't catch it Everything is the other way around, I approve the poster, they print it and send me a package of half a ton. After that, we distribute them to schools, large organizations and science museums, with the Israeli Academy of Sciences paying for these shipments."
This time you will get to translate a poster that you are the star of...
Prof. Shechtman: "They will also consult with me about my poster. I know they are doing this because Ada Yonat, the winner of the 2009 Nobel Prize in Chemistry, told me."
"A second example of a volunteer project that I have been conducting for 25 years: this is a technological entrepreneurship course at the Technion whose goal is to encourage our graduates to open start-up companies. They have the technological training but they also need training to be entrepreneurs. I try to infect them with the entrepreneurship bug. Initially I had to Fight to teach the course. Today it is a large course of 300 students. The course is based on guest lecturers and many of the leaders of the industry in Israel and lecturers in the course, including the president of the Technion."
"Besides these areas of volunteering, I sit on committees, and take positions in the Israeli Academy of Sciences. For example, I served as the chairman of the division for natural sciences. Today I represent the Academy in the Organization of Asian Countries. I am doing it for the glory of science in the State of Israel."
You talked about the education system, what about the media?
There is a senior role for television in education, because the youth watch a lot of television. I propose to prepare a project and even manage it, within the framework of which films will be produced describing scientific professions, what a mechanical engineer does, what a scientist in biotechnology does from morning to evening. In the USA - the NIH took it upon themselves to make such films about the medical professions and episodes in which they follow, for example, a biotechnological scientist, a doctor who is also a researcher, what does one who studies the human genome do. In my opinion, these films are not good. Although the people filmed in them are real scientists, they do not have Chaim, like one who is single, without children, and she explains her science. No girl wants to be like that. I would choose women or men who have good looks family, and start the film in the morning at home when, for example, you take the children to school. Then, of course, you can continue in the laboratory with a scientist in a white coat or a mechanical engineer discussing the airplane wing or the chip project."
"The idea came up a few years ago: I was returning by train from Ben Gurion University and I was sitting by a young and happy man. I started a conversation with him, it turns out that he is going to the BKOM to be released. I asked what you will do next - I don't know, I will go study accounting. I have an uncle who is an accountant and earns well, I will be too. I asked him what he studied in high school, and he answered: 'I was a good student in high school, math, physics, chemistry was just fine.' If so, then why don't you go study engineering? I asked and his answer was: 'I didn't think about it, I don't know any engineer.' And that needs to be broken, we need to teach a lesson in schools that will be called a subject lesson and in which they will teach the students what the options are before them." Prof. Shechtman concludes.
And of course it is impossible without the scientific aspect, the Nobel Prize Committee highlighted the connection between the golden ratio and your discovery. What is the relationship between quasicrystals and the golden ratio?
You need to go into a long and drawn-out analysis of what is happening. The golden ratio is a discovery by an Italian scientist named Fibonacci of Pisa and he published in 1202 a mathematics book in which he described what was later called the Fibonacci series: a description of rabbits that breed according to a certain rate and the series that is obtained in each breeding cycle. Let's say that each cycle lasts a month - it is a series of numbers that has many interesting properties, but what is relevant to our interest is the ratio between the number of rabbits in a certain month to the number of rabbits in the previous month to the number of rabbits in the previous month. The ratio obtained when aiming for infinity is an irrational number. This ratio is an irrational number called the Fibonacci number and also the golden ratio. …1.618033988 and so on to infinity."
"Some claim that the golden ratio describes a special aesthetic (1.618...). Some painters used it in their paintings and sculptures. I don't know much about art, but it is definitely an aesthetic number. The Fibonacci series describes a quasi-periodic series in one dimension. This means that it has no motif It is impossible to find a group of digits of any size that repeats itself. If such a group existed, it would be a number Rational and the series was a cyclical series. Here it is a non-cyclical series."
As mentioned, the Fibonacci series is quasi-cyclic in one dimension. If you want to describe a two-dimensional series, you can refer to the Penrose tiles, named after an English scientist of our time - Rothschild Penrose. This is a series in which no repeating motif can be found and it paves the plain in a quasi-cyclic manner without intervals. If you want to find an example of a 3D quasi-periodic series - it's a quasi-crystal, and that's how it communicates.
Do quasi-crystals have exemplary applications in the fields of computing or space?
"The applications of periodic quasi-crystals are few and unimportant. Applications of a material depend on its properties. For a material to have applications it has to excel in something and overcome other materials in the same field. Quasi-crystals excel in some fields but others beat it. The importance is not in the applications but in the scientific discovery itself, in the fact that we did not fully understand the possibilities in which atoms can arrange themselves in solid matter, and now we understand better and therefore also the definition of A crystal changed following the discovery."
Comments
heat,
You should try to talk to Prof. Shechtman, he will confirm what I wrote. And I repeat my words, Shechtman saw a phenomenon and did not understand it, and only after Prof. Ilan Blach explained the phenomenon with the help of a mathematical-physical model he built, did others also understand its meaning.
I am sure that Prof. Shechtman is a brilliant, important and great scientist, but as far as this discovery is concerned, the prize should have been divided between him and Belach (and I am not talking about money, it is not important)
Success has many fathers but failure is an orphan.
Even though there are great geniuses, there is still one
who discovered and pushed the discovery and credit is due
In the second round you should give the physical genius Ilan Belach
Also a credit and maybe also research grants because he is such an appreciated physicist
But only one discoverer validated his discovery and pushed his discovery.
And that is Schechtman.
Well, his actions as his words?
The respect that Professor Shechtman brought to the State of Israel in general and to the Technion in particular is tremendous. However, Prof. Shechtman says in a number of press and television interviews, and I quote from an interview he gave to the Haaretz newspaper on March 24, "On that day, the understanding that it was something new, but I didn't know what it was yet," he says today. And later Prof. Shechtman notes and I will quote again "I knew my observations were fine. I could not explain the phenomenon, but I knew it was a substance that no one had seen before, an impossible substance according to the laws of crystallography." And only one person, Prof. Ilan Belach, in a short time developed a physical model that explains the phenomenon...
And Prof. Shechtman continues and says "only then did he feel confident enough now to publish an article on the subject"
And the article was of course published together with Ilan Belach.
Before us is a case in which Prof. Shechtman saw a certain phenomenon but was unable to understand it and certainly not to explain it. Another brilliant scientist in his field (and all members of the Technion faculty will confirm this), understood, and developed a model that Prof. Shechtman and others could also understand.
It is true that Prof. Shechtman points out and quotes again "I would like to mention several people to whom I am indebted and regret that they are not sharing the award with me: especially Ilan Balch who wrote the first article with me and in which the physical explanation was laid out" is not enough, Prof. Shechtman should contact the committee in Stockholm and demand The distribution of the prize to the years, to Ilan Belach and to himself. In doing so, he will receive great honor, the Technion will also receive a special honor and the State of Israel will receive another Israeli bridegroom for the important award.

A million euros, currently it's about 1.4 million dollars
I understood that it was about $1.5 million, or is that all?
If he really thinks and believes this, shouldn't he share the prize with them in some way?

There is a more orderly way of doing things and in this way you can enjoy all the worlds.
My two sons studied in Bar Ilan's project, did a 5-unit matriculation in mathematics in the Yod class and then went to university at the same time as high school when the matriculation was already behind them.
Ron Gabrieli:
They should also know material studied in high school and not only infi.
Important, for example, on geometry. In the university, you usually don't bother with this, but it is an important and beautiful part of mathematics (unfortunately, even in high school today less geometry is studied than in my time and this is another mistake of the Ministry of Education).
If a student is really talented there is no reason to exempt him from matriculation in mathematics. After all, the intention is that he knew the material - right? If he really knows, then what difficulty does he have in passing the exam?
Matriculation in mathematics has an educational value and you have to go through all the stages in high school.
If you skip the matriculation in mathematics, it has a bad educational value.
A good friend of mine Prof. Avshalom Elitzur skipped the graduations and degrees and got a direct doctorate. So he invents and has ideas and is a genius. But I do not recommend this route in any way to any physicist.
A physicist has to go through all the steps - one by one - from beginning to end.
The academy is like a guild and the student is like an apprentice and also learns methods that are not explicitly stated in the lessons. And some of these methods are: "Go through all the steps, solve all the exercises, sit in all the labs and solve the exercises again and again and only then will you be an exemplary physicist."
And one of these stages is the matriculation in mathematics and physics.
Children who play at an early age with black holes, wormholes or the theory of relativity are creative and go outside the box, but they need to be educated that they need to work hard and go through all the stages - because there is an educational value in that.
Ron,
I also believe that the state should take care of all the students, including the children at the various ends. My argument is simple
The fact that there is no science class for children of primary school age is not a failure of the Ministry of Education. By the way, as far as I know, this is not the case either. There are special frameworks for gifted children funded by the Ministry of Education. In this framework they take
Children from elementary school go to a different setting one day a week where they are shown and they conduct scientific experiments and also learn mathematics at a different level.
so that
1. The Ministry of Education does take care of the children in the elementary school for scientific education. At least in some places in the country.
2. There is almost no connection between winning the Nobel Prize and being exposed to science in elementary school. The Ministry of Education has many problems that need to be addressed before complaining about the lack of exposure to science at the elementary school age.
3. The Ministry of Education does not need to translate websites. By the way, Kahn Academy is also a private initiative.
jelly,
In my opinion, the framework of university studies for high school students is a blessing. Such a framework did not exist several years ago and then every high school student who wanted to study at the university had to face multiple bureaucratic and social difficulties. The program of completing university degrees before the army has great success. Personally, I know a number of talented young people who completed a master's degree before the recruitment and from my acquaintance with them they do not suffer from a lack of general or specific knowledge in any profession, on the contrary their general knowledge is very broad and many times they surprise me in its scope. Therefore, in high school, each student should be allowed to progress according to his ability, and in this the Ministry of Education has greatly improved.
By the way, how is going to markets in school?
My argument was that the education system should not be blamed for failure if there is no exposure of children to science at elementary school age. Today there are many more options that include television and the Internet, although in my opinion personal intention is better, which can expose children to science. By the way, your claim that children in elementary schools do not have programs for exposure to science is not accurate (see my answer to Ron).
Michael,
I agree with you about a high school where learning can be accelerated, for elementary school children the school has other roles beyond imparting knowledge. At school, the child is exposed to the company of children of his own age and learns how to cope and behave in society. Acquiring knowledge can indeed sometimes be compressed into short periods of time, but the same cannot be done for the social side. By the way, also in imparting knowledge, there were attempts to reduce the duration of a bachelor's degree to two and a half years for talented students, and this was a partial failure. Many times it also takes time to digest the knowledge even with swallowing it without chewing.
Why is matriculation in mathematics important if the child gets a good grade in Infi at the university? Why not give a solution from matriculation to those who studied more advanced material successfully at university?
I do not agree that the state should only take care of the normal students, and that the parents should finance classes for the gifted and genius students. The state's responsibility for education is for all children, including the children at the edges. Special education should be the right of every special child, if he does not get along with the study material because it is too difficult or because it is too boring and easy.
If the Ministry of Education (or a private entity) were to translate, for example, the lectures and exercises b http://www.khanacademy.org In Hebrew then children could study on their own, and skip classes in specific subjects in their free time.
sympathetic,
My typo. electron and positron.
The debate here has become interesting and it is good that we are talking about the issue of science education because it is important.
My eldest son is 16 years old in the XNUMXth grade (here you will meet the whole family... and in a little while I will also tell about our dog Shuki... 🙂 😉 )
Last year he started studying at university. I didn't think he should start studying at university. In my opinion, a child in class Iod should not start studying at the university. There are other children from his school who started studying at the university - there is a special program at Haifa University for high school students and there is a program at the Open University. And it turns out that the students are not doing so well because of the stress in the final exams. This year I told my son not to enroll in courses at another university, it would hurt his matriculation this year in the 11th grade. And he didn't enroll.
What happened is that students who started studying at the university in the iodine class thought: "I study infin at the university so I no longer need a matriculation in mathematics". Then they invested in university studies and deteriorated in school studies. And actually this thought is not true. Because you need the matriculation and matriculation in mathematics even if you take the course of differential and integral calculus.
Therefore, going to university at the same time as high school is not wise!
What is really smart is the plans of the Ministry of Education for students. Like for example my son is going to the vault burning competition at the Weizmann Institute. This is a great physics program. And there are other science programs that are within the Ministry of Education and are adapted to the child's age.
sympathetic:
What I suggested in this regard is that perhaps it would be worthwhile to advance everything - including the study of the mathematical basics.
In my opinion - in one year at the university they cover more material than in elementary and high school combined and I am not sure that this situation is forced by reality.
Michael,
I also had good teachers that I remember from the beginning and it is possible that they influenced the course of my life. I also remember scientific questions
that interested me at that age. A good teacher is something that is important to have regardless of what he teaches.
The main point of my argument was against accusing the Ministry of Education of failure by not promoting science in school
the elementary For this purpose there are classes, parents who can ask questions and even television programs. There is no connection between primary education
and Nobel Prizes. A problem with the Ministry of Education is that it follows changing fashions and does not teach the basics.
We need to support more people in the Ministry of Education and the character of the teacher in general, maybe then more good people will come to teaching
Although in today's society most things if not all are measured in money and therefore maybe only high salaries will solve some of the problems.
sympathetic:
Although one should be careful (in my opinion - there is no reason to avoid it completely) in learning things before the foundations have been laid - but this has nothing to do with age.
In other words - it is definitely possible that it is worth teaching everything earlier and that nothing bad will come of it.
Something interesting from my personal experience as a child:
Part of my time in elementary school (the part where I stayed in Israel) was spent at State School D in Neve Magen - Ramat Hasharon.
My teacher for Teva was Tova Messer - Hagit's mother Messer Yaron (Hagit was in the same class).
I remember her teaching us about ideal gases. Still without the kinetic model of the gases and showed us how to deduce the existence and size of the absolute zero as a result of the linear decrease of the size PV as a function of the temperature.
Some time after that we learned about conductivity and resistance coefficients of different materials as a function of temperature.
On a personal initiative, I took the coefficient of resistance of one of the materials we learned about (I don't remember which one) and checked for myself if the resistance would reach zero at the same temperature where we discovered that PV would reach zero for ideal gases.
Amazingly, I got the same result and there was no limit to my joy.
All of this happened without knowing anything about the derivation of the ideal gas formulas from the kinetic model of gases, but there is no doubt that it was an enriching experience that increased my love for science (and yes - you could say that I "predicted" superconductivity, without knowing anything about quantum theory).
I didn't understand. How would experiential science, which was acceptable to me, solve the test case you left at the beginning of your words? Your son didn't ask you questions about experiential science but about "what happens when an electron and a proton inhale?". Would experiential science give an answer to these kinds of questions? Basically I think to teach the basics and also to stimulate the children's curiosity. This can be done in the circle of experiential science but is not necessary. Again, the Ministry of Education should not be blamed for failures, it just has real failures that must be corrected.
By the way, a class for yoga, chess, drawing, computer graphics, basic programming, juggling, cinema are all classes that should have been included in the basics. There is no limit to the demands, because parents are consumers and the customer is always right.
post Scriptum.
An electron and a proton do not annihilate, only a particle and an antiparticle do annihilate, i.e. an electron and a positron.
I would actually start science programs for children in elementary school as part of the curriculum. Especially experiential science, i.e. science in the laboratory: physics and experiments. Discovery Channel had Mythbusters. Laboratory classes in physics and chemistry are suitable for children of elementary school age: experiments for children in physics and chemistry.
A children's robotics laboratory, suitable for children of elementary age, in preparation for entrepreneurship.
It is experiential science, science and technology through the senses and learning through it is excellent science.
If I were a school principal... (which I probably won't be... :)), this is what I would do in my school: introduce laboratory classes in physics and chemistry and a laboratory in entrepreneurship.
jelly,
The Ministry of Education does not and should not have a science plan for elementary school. The Ministry of Education has not failed in this matter! As a rule, children of elementary school age lack the knowledge necessary to study science at such an age, all that is needed is to arouse their curiosity and give them basic tools. Soon parents will demand algebra lessons in kindergarten and blame the kindergarteners. Of course this is about the rule, there are always exceptions to the rule and they should be treated in special frameworks funded by the parents and not the Ministry of Education.
The state should have no interest in teaching elementary school-age children science. Some Nobel laureates
Received a basic scientific education? I am ready to guarantee that not even one of the Israeli winners received a scientific education
Fundamentally. When you read biographies of the great scientists, you see that they did not receive a basic scientific education
It was always a relative who recognized the talent and challenged them with questions as children.
Talented children will develop and become great researchers even if they only start studying in high school. It is important to give
For children to grow and develop naturally so they can communicate with their peers. Experience teaching science at a level
High in elementary school is pathetic and even worse dangerous. As I already wrote, to the Ministry of Education
There are many sick people but this is not one of them, in this matter it is not a failure.
Yehuda:
I also only agree 100% with Ehud's last response (the one I thought you were responding to).
In my opinion there is a place to give the child a sense of theories that he does not yet have the tools to understand and analyze in depth and on the condition that he is explained that this is what is being done and that it is not a substitute for in-depth study.
In fact we all learn this way at one level or another.
We all sometimes operate devices that we do not fully control the mechanism of their operation.
This is obvious when it comes to electrical devices, but on a certain level it is also true for mental devices.
Michael,
I will pass the questions on to my child…. 😉 🙂 😉
to love About my little son. He is particularly strong in mathematics and calculations. And with him this is exactly the failure of the Ministry of Education. The Ministry of Education has no plans for children like him in elementary school. So he reads alone the books that are at home and what is on the computer.
In high school they have an excellent program for mathematics and physics 5 units increased. My older son also has excellent teachers at the Carmel Beach School for these subjects. My son is going to the Shalhab vault competition at the Weizmann Institute - and these are great programs. Last year the school had a robotics competition and there are always science and technology competitions and science and technology programs.
But the elementary school does not, simply does not have programs for science. And this is exactly what I wrote, that the Ministry of Education has failed with the children who are gifted in science in elementary school.
On second thought
Not to all of Ehud's words
I am of the opinion that science and the theory of relativity should be taught earlier in the higher grades of elementary school.
Happy Holidays
Sabdarmish Yehuda
Dear Mikael
My words refer to the article to the words of Avi and Shechtman. Well spoken
On second thought also to Ehud's words
(:))
Happy Holidays
Sabdarmish Yehuda
I find it appropriate to clarify that Yehuda's words probably refer to Ehud's last response (which I completely agree with you) and the fact that my response managed to get in front of them is an unfortunate coincidence.
Well done
Well spoken!
Sabdarmish Yehuda
jelly:
Following Ehud's words regarding the riddles, here are some questions you can ask your son so that he can progress in self-reflection:
One man finishes his work every day at 16:00 p.m.
At the end of work, he gets on the train (exactly at 16:00) and gets off at the station closest to his home.
His wife leaves the house with her car and arrives at the train station with him.
He gets off the train straight to the car and they go home.
One day (on the holiday) there was less work and he left work an hour earlier (ie at 15:00 PM).
His wife did not know about this and left the house at the usual time, so when he reached the train station, he started walking towards the house.
At some point along the way he met his wife, got in the car, and they returned home.
When they got home he looked at the clock and saw that they had arrived 10 minutes earlier than usual.
Assuming that the speed of the train is constant, the speed of the car is constant, the walking speed is constant and no time is wasted on stops - how long did he walk?
Are there two non-bald people in the State of Israel who have the same number of hairs on their heads?
Assuming that friendship is a symmetrical relationship (explain to him what a symmetrical relationship is) - must there be two children in each class whose number of friends in the class is the same?
A man is standing in an elevator that begins to fall in free fall.
He can reduce his fall speed by dodging (which reduces his fall speed relative to that of the elevator).
Assuming that he can see the ground, his distance from it and the speed of his fall - what is the right moment to jump?
Why do palm scales balance when the weights on both paws are equal and why - when the weights are different - they get an angle that characterizes the weight and do not stand perpendicular to the ground.
Why - when you fold a sheet of paper - is the resulting fold always a straight line?
To everyone else:
These are questions for Gali's child and don't try to answer them here.
Regarding the employees of the Ministry of Education:
In Israel, unfortunately, there is no educational tradition and the tendency is to get carried away by passing fads.
The social perception is the consumer, the parents and the students see themselves as consumers of knowledge and
The teacher is responsible for providing it. Since the customer is always right, parents feel entitled to intervene in the children's education and say
For teachers what and how they should teach.
Regarding the teachers, Prof. Shechtman is right, most of the teachers today are female and why is this so?
The basic assumption is that teaching is not a main profession but a temporary profession intended
to supplement the family's livelihood. Teaching is a field for a mother who wants to do something but
Also wants to prepare lunch for her children and be with them. This is not a profession where there is an option
To promote a professional challenge and therefore also the salaries accordingly.
The state does not invest enough in education even though recently the situation is improving, why?
Poltkas do not tend to make long-term investments because in their current term they do not
They will see the fruits. Therefore, it is possible to save money by taking it out of long-term projects
Like defending against fires and earthquakes for example. If a fire or earthquake occurs
Adama can be blamed on the previous governments, because they also neglected the issue and thus
avoiding hospitality. Even in education, this phenomenon is prevalent when failure or successes are an issue
of many years.
Fortunately for us, the Ministry of Education still does not teach students about black holes, quanta and relativity in elementary school, and it might even be desirable to avoid this in high school. Science is built on levels of knowledge. If you don't understand the basic level in terms of the math and the basic equations, there is no point in talking about the levels above. A student who has not studied basic mechanics and talks about general relativity has no idea what he is talking about. Quoting from Wikipedia or learning definitions are not equivalent to understanding.
Fortunately, the Ministry of Education has not yet fallen into this trap. Studying science from popular science books creates an illusion of understanding and mental shallowness. In order to start studying science, a basic curiosity about the world of phenomena accessible to us is needed, an attempt to understand why the world we see behaves the way it does. Questions and riddles are a good way to encourage curious youngsters. Anyone who gives popular science books to children or is enthusiastic about their wishes on concepts that they do not understand at an adequate level encourages mediocrity and shallowness of thought.
Prof. Shechtman's entrepreneurship course is an amazing thing!
It's just a shame that it is not accessible to those who are not students or faculty members at the Technion:

I forgot the second part...
The role of the teacher is to fulfill the role that the parent cannot fulfill. Science programs for elementary school age and a professional and good science teacher at school can target students who are curious about science from an early age. And the education system has no answer for students who are curious about science. No, there is simply no answer for students like my little son and that's why he is like this with a lot of questions in science and reads Wikipedia that is not suitable for his age. There are simply no programs in the education system that are suitable for children like my son.
My father, you look good next to Shechtman... maybe a little of the Nobel will stick to you? 😉 🙂
My little 9 and a half year old son already reads science books by Michio Kaku and The Particle Hunter by Yuval Naman and encyclopedias of science and reads Wikipedia entries in science. He can explain to you what black body radiation is, about black holes, the big bang, the theory of relativity, quanta, virtual particles. And he also performs long mathematical calculations. He asks me questions and I don't have the strength to answer all the scientific questions because there are so many questions a day. And I have to cook, tidy up and walk the dog and think about other things and think about the dishes I need to put in the dishwasher and think about whether someone has set foot on me today and how I plan my trip and how I go to this conference and how I do it... and then he explains I have his long math calculation and in the middle I'm thinking about the lecture I'm going to give. And then, mother, you don't listen to the virtual particles and I think there won't be any virtual particles, and what happens when an electron and a proton inhale? Then I think about the egg that boiled on the gas and then another question comes to me, Mom, what is Casimir power? Then he answers me: When you don't answer me right away, then I go to Wikipedia and there I immediately find the answer. This is how it is to raise a child who is so talented in science and math and I just can't keep up with him because I have to function as his mother. So he reads alone…
