Richard Dawkins: “Not accepting the theory of evolution is crazy!”

The great ethologist, evolutionary biologist and popularizer of modern science, Richard Dawkins, in 2012, met with Archbishop Rowan Williams on one of the airwaves, who convinced and continues to convince everyone around that life on Earth appeared by the will of God.

Richard Dawkins carefully listened to the archbishop’s fantasies and conjectures, and then told his interlocutor about the theory of evolution and told the details of the origin of life on Earth. Airtime was limited, so Dawkins presented the information in a compressed form, but that was enough.

“I am inspired by the elegance of your explanation. Your arguments are beautiful and I can even agree with some of the above. However, the Universe, creating a person, was guided by clear principles and this can speak of a certain higher mind, ”said Rowan Williams.

“I can’t understand why believers do not want to see beauty in the fact that life could have been born from scratch and absolutely by accident. Isn’t that a stunning and not a great idea? Why does everything need to be distorted? Not accepting the theory of evolution is crazy, ”Dawkins responded.

The discussion between the archbishop and the scholar lasted more than an hour and at the end of the dialogue Dawkins admitted that on a 7-point scale he considers himself an atheist at 6.9. In other words, Richard Dawkins will be ready to believe in God if believers provide irrefutable evidence.

Why are we all addicts

Do you want a little happiness euphoria and joy and absolutely legal? Just find what you like to do, do it regularly and gradually increase the dose. It can be anything: computer games, flipping instagram feeds or TV shows. The bottom line is pleasure. But if so, then it turns out we are all really addicts? In general, yes. And that’s why.

Almost all substances that change consciousness aim at the brain reward system, achieving the release of dopamine and the pleasure of artificially. Over time, the brain decides: “something is a little too much dopamine, but will you die of happiness?”. In response, it begins to independently produce fewer neurotransmitters and reduces the number of receptors in the same promotion system. This is called chemical tolerance. It works as a guard against madness and forces addicts to constantly increase the dose in order to achieve the same effect as before. This leads to serious changes in neurons and other brain structures. In the long run, all this will cause severe health damage.

However, drugs are different. In addition to the standard objects of addiction, which immediately come to mind like gambling, alcohol, cigarettes and, respectively, opiates, American scientists also include addiction to a smartphone, caffeine, shopaholism, workaholism, and even sports. But here they also recognize that the line between addiction and obsessive-compulsive disorder is very thin. And this is a topic for a separate study.

The sports example, by the way, is very revealing. Right before training, your brain prepares for the worst. He doesn’t care what exactly awaits you. Heart palpitations, shortness of breath, dizziness, cramps, muscle pain. For the body, this is stress in any way, and in order to protect itself from it, the brain produces BDNF protein. It is because of it that after training we are almost happy. In addition, endorphin production increases in response to stress. They block pain and give us a feeling of euphoria.

Dr. Carter Stout, a Los Angeles-based psychotherapist, is expanding our list of addictions to the limit. In his opinion, the obsessive need for sarcasm with an increase in the scale of problems should be attributed there, as well as longing. Here, scientists include the most important drug addicts – mothers of newborn children. The fact is that during childbirth, both the mother and the child increase the level of endorphins to an incredible level. At the same time, the hormone of love, oxytocin, is produced, which is responsible for ensuring that the mother loves and protects her offspring. So at first, the woman seemed to be under soft drugs, otherwise it would not work. You can go crazy with such stress.

In general, your good mood and happiness depends on four substances: dopamine, serotonin oxytocin and endorphins. Well, of course, the development of natural opiates in the body can be promoted. For example, according to the data center of the memorial Sloan kettering cancer center in New York, patients who inhaled vanilla aroma before an MRI scan in 63 percent of cases were less likely to experience anxiety. Participants in another 2013 study inhaled the scent of lavender and noted improved sleep quality, a significant reduction in symptoms of depression, insomnia, and unmotivated anxiety. And ginseng performed well in the fight against physical fatigue and mental stress. All thanks to the stimulation of the production of endorphins.

In addition to satisfaction, calmness and happiness, we can experience positive emotions from stress. For example, excitement, the joy of victory or the pleasure of risk. Norepinephrine is responsible for them. Not to be confused with adrenaline. This is the main mediator of the sympathetic nervous system, which controls motor activity and our internal organs. During stress, emotional and physical stress, and generally large energy costs. A special example of its action: it is difficult for us to sit still if we are stressed and nervous. This is the effect of norepinephrine.

In general, our body is maximally imprisoned for positive emotions and to learn how to experience them regularly is possible and even necessary without artificially stimulating substances. The main thing to remember is that it is not necessary to constantly feel happy. It’s normal to be sad. After all, nature has rewarded us with a wide range of emotions for a reason, and that we use it. Everything is good in moderation.

India will send a humanoid female robot into space

India plans to launch a test unmanned mission with a Viom Mitra robot on board in December 2020.

The Indian Space Research Organization (ISRO) for the first time showed a prototype of a half-humanoid robot that they plan to send into space as part of the ambitious Gaganyaan national program, informs Times of India.

The humanoid robot’s name is Vyom Mitra (Vyommitra: viom (translated as “space”) and mitra (“friend” or “deity”). According to Vyom Mitra herself (this is a female robot and she can speak both English and in Hindi), she is able to “imitate” the activities of astronauts, conduct conversation and answer questions.

As ISRO scientist Sam Dayal explained, Viom Mitra is considered only half humanoid, since she has no legs, she can only lean sideways and forward. “The robot will conduct experiments and liaise with the command center,” the representative of the Indian Space Agency added.

They plan to send a female robot into space at the end of 2020 – this launch will mark the first unmanned flight of the Indian spacecraft Gaganyaan as part of the eponymous program. The second unmanned launch with Viom Mitra on board is scheduled for June 2021, and the Indian astronauts themselves can go into orbit before the beginning of 2022.

“Our country has made great strides in space. But our scientists have a dream. In 2022, when the 75th anniversary of independence approaches, an Indian – no matter whether a man or a woman – will go into space with a three-color flag in his hands, ”said the country’s Prime Minister Narendra Modi in 2018.

Russia has volunteered to help implement these plans and train Indian cosmonauts. Four male pilots have already joined the Gaganyaan launch mission, and the Geosynchronous Satellite Launch Vehicle Mark III booster rocket, which will launch them into space, has previously completed three successful launches.

This is how China manages to turn the bus terminal of 30,000 tons in 90 degrees

In our era of giant construction giants, it is an equally impressive engineering feat when a building weighing thousands of tons is demolished again. Can the human ingenuity increase by surpassing such triumphs? Yes, it can. For example, if you decide not to simply demolish a building that stands in the way of a construction project, but relocate it in one piece. Watch the video below.

The bus station you see in this video is located in Xiamen, China. The building as a whole weighs 30,000 tons, which makes these scenes even more impressive: this weight corresponds to 170 Boeing 737. Together with a central point, the entire terminal was rotated 90 degrees, which corresponds to a distance of 288 meters in its outermost extension.

The complex got in the way of the planned construction of a station for high-speed trains and, therefore, had to give way. Now, behind this relocation, contractors hold the world record for the “longest arc rotation of a pivoting building”, made possible by hundreds of hydraulic supports mounted on a rail system, as shown in the video.

An impressive technical achievement from which one can only take off his hat, and above all, these are images that one does not see every day.
