What rare word did the museum owner use to get rid of slow visitors?

One day, Phineas Taylor Barnum, the greatest American showman of the 19th century, decided that visitors to his "American Museum" in New York were looking at the exhibits for too long. He ordered signs to be posted with the inscriptions "This Way to the Egress", which translates as "This is the way to the exit." The point was that the word "egress" is quite rare, much more often the exit is denoted as "exit". Most visitors thought that these signs lead to the most interesting exhibition, but, following them, they found themselves on the street.

 Random interesting fact from the Great Encyclopedia:

What is a molt?

When an animal sheds its skin or feathers, replacing them with new ones, we call this molting. Beasts, reptiles, birds, and even some insects molt. Birds grow a whole range of different feathers in their lifetime. Upon reaching adulthood, the plumage takes on a typical adult appearance, after which, as it wears out, the old feathers fall out and new ones grow in their place. The same thing happens after pulling feathers. In addition, some birds grow bright new feathers during the mating season.

Thus, most birds molt twice a year: before and after the mating season. Since almost all birds do not shed many "bearing" feathers at the same time, they do not lose the ability to fly during molting.

In addition, in order not to disturb the aerodynamic balance, the feathers are dropped in pairs: one on the left, one on the right. The exceptions are ducks, geese and swans, which lose all their feathers during molting and cannot fly. But since they are waterfowl, in order to elude danger, they do not need to take off, it is enough just to go into the water.

During molting, brightly feathered males often take on a solid color, which provides them with additional camouflage.

The snakes are very interesting. They do not shed all the skin at once, but only a small extreme part. The snake rubs its head against something to free itself from the skin around the mouth, then it hooks the exfoliated parts of the skin on stones or branches and crawls out of the old skin head first, leaving it inside out.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Hidden identification with invisible QR codes 01.09.2023

A team of researchers from the Massachusetts Institute of Technology has introduced an innovative identification system called BrightMarker, which has unique properties. These tags, visible only in the infrared spectrum, open up new horizons in secure tagging and tracking technology, which is considered more reliable than the widespread traditional QR codes popularized amid the global coronavirus pandemic.

The essence of the technology lies in the introduction of unique marks into objects during their production using special fluorescent threads. It is important to note that these labels have absolutely no effect on the characteristics and functionality of objects. To detect such tags, a number of hardware devices have been developed that are easily integrated with smartphones and virtual reality headsets.

The researchers believe BrightMarker technology has potential for a variety of applications. Invisible tags can authenticate items and track their movements, while still providing the functionality of regular QR codes. However, it is worth noting that BrightMarkers can only be applied to objects created using XNUMXD printing, which limits their scope.
