TECHNOLOGIESCameron’s abyssTim SkorenkoThe highest point of the globe – Mount Chomolungmu – has been conquered by 4,000 people to date: one might say, not a mountain, but a courtyard.

THE SCIENCEElectric tasteIt often seems that everything useful is necessarily tasteless, and everything tasty is harmful. But what if the dullest cottage cheese or the most boring oatmeal, which will seem divine, crispy fries? .. Or ice cream? .. So everyone will become a fan of healthy eating! It remains to wait for the Singapore engineer Ranasinghe Nimesha to complete the development of the electric taste simulator.

THE SCIENCEKind brother MorphiaLife is pain, and sometimes, alas, it is not at all metaphorical. Some patients have to wage a constant and almost hopeless struggle with it.

TECHNOLOGIESAnd supersonic againWhen the era of Tu-144 and "Concordes" ended, it was customary among aviation experts to express themselves extremely skeptically about the revival of civilian supersonic sound.

GadgetsThe near future is on handAlexander the GreekOne of the main trends in the watchmaking world is the appearance of such a modern material as carbon composites in the models of the upper class. Carbon is considered the main material of the 21st century. Two already synthesized materials are graphene (for the creation of which the Nobel Prize has already been awarded) and carbon nanotubes. Composite materials created on the basis of the latter, with similar strength characteristics, are five times lighter than steel and three times lighter than titanium. In addition, carbon composites are non-magnetic and hypoallergenic, which is important for watches. In addition, while this material is quite expensive: the price of nanotubes exceeds $ 15,000 per kilogram, that is, they are only half the price of gold.

ARTWhat is natural is beautifulThe history of architecture and design is the history of styles. Style is more than just a collection of artistic devices, techniques or technologies. Baroque, classicism, empire style, modernism, rationalism, minimalism and other styles influenced not only how buildings, interiors, clothing and even weapons looked in these eras. They have completely defined the society’s ideas about beauty. Parametric, or algorithmic, architecture has existed within the framework of avant-garde design for more than a decade, but recent advances in computer technology have allowed it to claim to be the leading style of the new digital age. This is definitely not an instant fashion.

THE SCIENCESchool of the XXI centuryAlexander the GreekOur children have to learn much more in school than we do. And their heads are the same size as those of their parents.

But even this memory is enough to unmistakably recognize her.

EDITORIALWhat do crayfish and satellite TV have in common?People are rightfully proud of the structure of their eyes, although mantis shrimp have more reason for this. Our vision relies on the work of only three color receptors, and in crayfish their number can be up to 12, partly covering infrared waves and ultraviolet light. We are unable to imagine the variety of shades that shimmer in the coral reef in these complex eyes. But crayfish, as if this is not enough: thanks to special filters, many of them are able to distinguish and the circular polarization of light.

THE SCIENCEModern biological laboratory: the future is hereYulia KondratenkoIf a scientist tells you that he is doing his research in a cloud lab, he is not referring to cloudy weather at all.

When they are told what they were doing in the morning, they will be very surprised. "How? What? I was asleep! "
