What causes champagne to foam?

Not because of carbon dioxide, but because of dirt. In a perfectly smooth and clean glass, carbon dioxide molecules evaporate imperceptibly, and for quite some time it was believed that the formation of bubbles was caused by minor defects in the glass. Modern photographic methods have shown, however, that all these almost invisible nicks and cavities are too small for bubbles to stick to them, and that in fact the formation of bubbles is caused by microscopic particles of dust and fluff, which are invariably present in absolutely any glass. In the language of technology, it is the dirt / dust / fluff present in the glass that plays the role of condensation nuclei for the carbon dioxide dissolved in the drink.

According to Moet & Chandon, there are 250 million bubbles in any average bottle of champagne.

Chekhov's last words were: "I haven't drunk champagne for a long time."

German medical etiquette of that time required that the doctor, when there was no hope of salvation, offer the patient a glass of champagne.

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 ... >>

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. ... >>

Pedestrians are safer with robot cars 13.05.2012

Engineers from the Massachusetts Institute of Technology have found a way to solve the problem of communication between robot cars and pedestrians.

At present, many problems of automated transport have been practically solved: robots have learned to avoid obstacles, move in traffic, navigate on a map, and pass each other at intersections. However, it is impossible to introduce automatic road transport until the main problem - the safety of pedestrians - is solved.

Imagine the situation: you are standing on a pedestrian crossing and you see how a robot car rolls up to it, slowing down. Is it possible to transfer? Will the car stop or vice versa - it will rush forward? If a person is driving, you can understand whether he sees a pedestrian or not - in extreme cases, you can exchange gestures. With a robot, it's more difficult.

A group of engineers at MIT have developed a simple device that lets others know what's on the mind of a robot car. The system is equipped with several types of alarms. For example, when a car notices you, bright LED lights start flashing in different colors - from orange to red (depending on the distance). If the car does not see the pedestrian, then the lights are blue. Also, the robot-driver using the speakers can offer the pedestrian to cross the road or vice versa to stop. Thus, the robot can tell the pedestrian about his "plans" even more than a live driver.
