The theory of happiness. Accidents are nonrandom

The theory of happiness. Accidents are nonrandom 3r3618. 3r3-31. 3r33584. I continue to acquaint Habr's readers with chapters from his book “The Theory of Happiness” with the subtitle “Mathematical foundations of the laws of meanness”. This is not a published popular science book, very informally telling how mathematics allows you to look at the world and life of people with a new degree of awareness. It is for those who are interested in science and for those who are interested in life. And since our life is complex and, by and large, unpredictable, the emphasis in the book is mainly on probability theory and mathematical statistics. Theorems ...

We only fight with death, and you? Or companies that develop fantastic medicine

We only fight with death, and you? Or companies that develop fantastic medicine
 3r33434.
 3r33434. Hi, Habr!
 3r33434.
 3r33434. I want to talk about companies engaged in development and research in the field of age-related and aging diseases. It seems to me that it is necessary to draw people's attention to the problems of medicine, health care and aging in general, since these problems bring enormous harm to humanity in all its spheres. Aging and death are those things that unite humanity, no matter what your world view, material condition, status, race, age or health. Immediately I warn you that there may be many new and incomprehensible terms ahead, even though I tried to decipher ...

Numerical modeling in a large industrial company 3r3119. 3r31-10.  
Hello, Habr and his dear readers! 3r31-10.  
3r31-10.  
I was lucky. I work in a large metallurgical company, where innovations are valued, there is modern equipment, a good laboratory base, and partners all over the world. But this does not mean at all that it was easy to introduce and make needed a new research tool. I want to tell why we took up this topic, what obstacles we faced, what results we managed to achieve and where we want to develop. I will pay special attention to the question of why, with numerical simulation, we came to our clients. Welcome under the cut! 3r31-10...

Easily accessible levitation in ultrasound

Easily accessible levitation in ultrasound 3r3143.  3r3151. However, I just repeated the finished device described by in this article 3r3r79. . 3r3143.  3r3151. Brief information on the device and experiments with levitation are shown
in my video r3r379. (experiments 3r3321. begin at 2:0?
). 3r3143.  3r3151. 3r3143.  3r3151. The most important element of this device are ultrasonic piezo-emitters, which can be taken from a sufficiently popular ultrasonic distance sensor (on the aliexpress, search for “ultrasonic distance HC-SR04” at a price of 70 rubles). 3r3143.  3r3151. 3r3143.  3r3151. ...

I recently threw a cry in facebook 3r36363. and in 3r3133. Group "Severe techie" with a request to suggest what are the rescue systems at high speeds and at low altitudes. That's what managed to dig for this issue. The spread is large - from fiction to space systems, let's see what can be useful derived from this. 3r37474.

 3r31062. 3r31054.  3r31062. The vital question was whether this reaction could become self-sustaining. The temperature inside the ball of a nuclear explosion was supposed to exceed everything that was once observed on Earth. Is it possible that we will throw a match in a pile of dry leaves? 3r31054.  3r31062. Roger Penrose would resist this argument, believing that something unusual is happening in the brain at the quantum ...

China confirms leadership in the Asian lunar race

China confirms leadership in the Asian lunar raceIn the zero years in Asia, the second "moon race" began. Unlike the first, when the USSR and the USA competed in the 1960s, there were more participating countries, but budgets were smaller, and the general terms were longer. At the start there were three participants - India, China, Japan. Now a clear leader was determined. China took the lead in 201? having made a soft landing first and landed a lunar rover. The Chang'e-4 automatic interplanetary station flying to the Moon will make the first landing on the far side of the moon (which required a separate mission to provide communication) and ...

J’Accuse! Janna Kalman's 122-year longevity record - fake?

J’Accuse! Janna Kalman's 122-year longevity record - fake?For many gerontologists, Jeanne Kalman is almost like Jeanne d'Arc for the French. Symbol, legend, shrine. Record Jeanne d'Arle by life expectancy at 122 years and 164 days every true fighter with aging knows. It was installed in 1997 and since then nobody even managed to get close to it - the second place barely exceeds 119 years, and the third place is 117. Of the now-living survivors, the oldest are only 115 years old. Given that after 100 years of age, the annual probability of dying fluctuates around the 1/2 mark, the chances of sentiaries live to be 122 years old are incredibly small...
