Rear behold

Bible
Bible

Phraseologism: Rear contemplate.

Meaning: Not to see the true face of something, to know something is unfounded.

Origin: An expression from the Bible: God said that people should not see his faces, and if anyone looks, he will be stricken with death, only he allowed Moses to see himself only from behind: "Behold my back" (Exodus, 33:20 -23). Hence the expression "back to contemplate." "Our economists contemplate the back of the working class." (G. V. Plekhanov, Preface to "Vademecum" for the editorial board of "Working Class".

Random phraseology:

Simple as a moo.

Meaning:

About something primitive, extremely uncomplicated (jokingly ironic).

Origin:

From the "Prologue" to the tragedy "Vladimir Mayakovsky" (1913) by Vladimir Vladimirovich Mayakovsky (1893-1930): "Come to me, everyone who tore the silence // Who howled because the loops of noon are tight, - // I will open to you with words simple as a bellow, Our new souls, buzzing like lampposts."

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Methyl found in space 07.07.2023

Although the existence of active methyl cations in protoplanetary disks was suggested 40 years ago, it is only now that this important compound has been discovered and confirmed.

In 1977, a hypothesis was formulated that the monovalent methane radical, namely the methyl cation (CH3+), plays a decisive role in initiating chemical processes in the interstellar medium. However, detecting this molecular formation outside our solar system has proved extremely difficult.

Perhaps this is due to the high activity of methyl: its average lifetime in the free form is usually less than a thousandth of a second. As a result, it is unlikely to find a large number of such cations in one place and at one time, so that they can be detected using terrestrial telescopes.

However, thanks to an international team of astronomers, traces of methyl have been found in the protoplanetary disk d203-506, located in the Orion Nebula, using data from the James Webb Space Telescope and spectroscopic analysis. Star formation processes are actively taking place in this region, and d203-506 is the embryo of a relatively small star system: the mass of its star is approximately five times less than the mass of the Sun, and the mass of the protoplanetary disk is ten times the mass of Jupiter.

Where does this active cation come from in the protoplanetary disk? The researchers suggested that the reason lies in the strong ultraviolet radiation of Orion's Trapezoid, a compact cluster of stars located nearby. Under the influence of such radiation, hydrogen molecules (also found in the d203-506 composition) go into excited vibrational states, which makes them very active and facilitates their interaction with carbon, resulting in the formation of free methyl.

However, as the scientists note in an article published in the journal Nature, there are still several questions related to the excitation, chemical properties and spectroscopy of this molecule. Additional research is needed to definitively understand the role of CH3+ in the organic chemistry of the cosmos. This is important for elucidating the mechanisms of formation of more complex compounds in young stellar systems.
