First exposure - letters that Zvi Yanai wrote to his twin children inspired by nature

This week marks two years since the death of Zvi Yanai (1935-2013) * For seven years, Zvi Yanai wrote letters to his two young children, the twins Daniel and Yael Hochberg Yanai, when they were at the Kimama summer camp. The letters were the thing he was waiting for the most. * The letters courtesy of his partner Dalia Hochberg and the website of thoughts

Zvi Yanai, as Ariana Melamed wrote, was, quite simply, one of the greatest people of the clusters and spirit who lived here: a perfect autodidact with an intellectual curiosity that knew no rest until the day of his death; A rationalist, a devout secularist, a humanist and a skeptic from the core of his soul, who knew how to mediate between distant scientific worlds and laymen who are hungry for knowledge.

Zvi Yanai, served as Director General of the Ministry of Science and won the Sapir Prize in 2008 for his book "Your Sandro". Edited the journal "Mechvot" and designed the interdisciplinary line of this journal on science, culture and thought. His formal education was 10 years of study and Prof. Asa Kosher said that his education is equivalent to at least 5 second degrees.
His huge library was donated by Dalia Hochberg, his partner, to the high school in Dalit al-Carmel. She established the site not as a monument or commemorative archive, but as a living and breathing manifestation of ideas. No, they didn't get old.

Recently, the journal website was launched Thinkil thoughts And a page on Facebook containing all the writings of the late Zvi Yanai - five books, dozens of issues, hundreds of articles and thousands of issues of thoughts, as well as audio and video clips and many other materials, which left a mark on social life, culture, science and art in Israel.

For seven years, Zvi Yanai wrote letters to his two young children, the twins Daniel and Yael Hochberg Yanai, when they were at the Kimama summer camp. The letters were the thing he was waiting for the most.

First of all, correcting a mistake. I attributed the Valentine's Day to Tu Bashvet (which is the holiday of the Ilanot) instead of Tu Bab (which is the Valentine's Day), which means that I love you twice a year. Actually, the mistake is not that big. Although plants do not speak and do not write love letters to each other, they certainly pass messages to each other in the chemical language.

For example, swarms of moths lay their eggs on birch trees in northern Scandinavia. The larvae that hatch from the eggs feed on the spores of the tree's leaves, but the whitefly does not go over this predation in silence. He transmits a chemical transmitter to his neighbors, and they send him back by sending pest control chemicals to strengthen his defense against the larvae. In another case, when caterpillars attack a bush of tomatoes, the leaves release chemical compounds that repel the caterpillars and at the same time warn their neighbors about the pest attack.

And on another matter, yesterday I saw the Israeli film "Howl of the Wolves", which tells the story of a pair of wolves and their offspring in the Golan Heights. The photos are spectacular, the puppies are cute, but the film itself is one big bore, and it's good that I spared you watching it, because the attempt to tell about the lives of the wolves from the mouth of the tribe leader is stupid and childish. Even Lola got bored when I told her about the movie (by the way, I was the only viewer in the cinema).

And if we are talking about wolves, the domestication of gray wolves began 15 thousand years ago, and they are the parents of 400 different breeds of dogs all over the world (including Lola). As amazing as it sounds, all of these breeds, from the dwarf terrier (the size of a beer can) to the giant Dane (the height of a donkey), are of the same species. That is, basically everyone can violate everyone. Despite the huge differences in appearance, one gene is enough to determine whether the dog will look elegant and long-legged like a waisted starling or squat and short-legged like a dachshund.

It's only been a few hours and I miss you already.

The first day is always the hardest and most annoying. Until you arrange your rooms, until you arrange your clothes, until you get down to business - everything is a bit stressful. So take a deep breath and think that within a day or two everything will be fine. Just think that a bee's brain is one millimeter in size, and it only has a million cells (compared to our 100 billion), yet it has to build cells for babies and cells to store the nectar and find the source of the nectar and identify the area route, and all this without getting stressed. So use the many cells in the brain and help each other.

The cute Daniel and Yael

This time a sad story. Yesterday they showed cute dying dogs on TV, abandoned by their owners in a field or on the street on the way to their flight abroad. Every year this cruel act repeats itself. People go on a trip abroad, and instead of depositing their dogs in kennels, they simply take them by car to a place far from home and leave them in a field or even tie them up to die of thirst and hunger, in order to save money that they would have had to pay to the kennels for their care in their absence from the country. Some of the dogs were saved thanks to good people who picked them up and brought them to a dog clinic, where they received an infusion and recovered from the ordeal. We have already talked about it several times. Raising a dog at home involves a lot of responsibility. The dog calls its owner like a child calls its parents, but since it is "just a dog", it is mercilessly abandoned. In my opinion, those who are cruel to animals will end up being cruel to humans as well.

Time runs fast. The weekend is almost here. According to the report we received from Kimama, you are very busy. I was happy to read that the Maya tribe visited the sea turtle rescue center. These animals are very interesting and special, partly because of their sea journeys, and this time I want to tell you about one of these species.

Tortoises leave Central America on a journey of thousands of kilometers towards a small island in the ocean. There they lay eggs on the beach, cover them with sand and return to their country. Two months later the little turtles hatch. There is no one to take care of them and no one to teach them what to do, because their mothers left the island a long time ago. Despite this, they know that they must run with all their might toward the sea, because those who do not enter the water quickly enough will be devoured by birds of prey.

And this is where the great puzzle begins: how do these little ones know that they should return to their mother's country of origin in Central America, a place they have never been to? How do they know how to navigate their way on a sea journey of 3,000 kilometers, towards a shore they have never seen? In fact, although most of them are devoured on the way by marine predators, the survivors manage to land on the exact same beach that their mothers left. There they will grow, and not long after, the young mothers will leave for that small island in the ocean to give birth to a new generation of turtles.

Another wonderful chapter in nature's fascinating adventure book.
