Which mathematician accurately predicted the day of his death using an arithmetic progression?

The English mathematician Abraham de Moivre, in his old age, once discovered that the duration of his sleep was growing by 15 minutes a day. Having made an arithmetic progression, he determined the date when it would reach 24 hours - November 27, 1754. On this day he died.

Was Tsar Ivan the Terrible a great ruler?

Some historians believe that it was, but what is its greatness - they explain rather confusingly. At the beginning of his reign, Ivan the Terrible won two wars - he conquered the Kazan and Astrakhan khanates. All other wars started by Grozny were successfully lost. The capture of Kazan and Astrakhan somewhat weakened the Tatar threat, but did not eliminate it at all.

Fifteen years after the capture of Astrakhan, the troops of the Crimean Khan approached Moscow. The tsar, who was stationed with an army in Serpukhov, fled to Aleksandrovskaya Sloboda, and from there to Rostov, leaving Moscow to its fate. Moscow was burned, more than 200 thousand people died in the fire, about 150 thousand more Tatars were taken away in full.

What Ivan was really great in was his cruelty, which amazed people even in those merciless times. During the capture of Kazan, almost the entire male population of the city was slaughtered. When the tsar undertook to subjugate Novgorod, allegedly about to surrender to the hand of the Polish king, more than a hundred thousand people were killed in the city. People were executed in the most brutal ways, along with their wives and children.

Mass executions accompanied Ivan's entire reign. He left behind a devastated, bloodless country.

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. ... >>

Furnace for radio lovers 01.07.2015

With the transition of mass broadcasting to online mode, the use of radio frequencies has become the lot of taxi drivers (for listening to Road Radio) and employees of large logistics companies (for searching for goods using RFID tags). However, thanks to a new invention, radio waves will soon be able to return to every home - to heat food.

The American company Freescale Semiconductors is one of the pioneers in the production of semiconductor components. In its 65 years of existence, it has become a leading player in the automotive, embedded systems and communications equipment markets. At a technology forum just held in Austin, Texas, the firm unveiled the world's smallest single-chip module for use in the "Internet of Things" - a future computing network of physical objects ("things") equipped with embedded technologies to interact with each other or with the external environment.

Among such things, Freescale Semiconductors sees kitchen ovens. But not the usual microwave ovens, but ovens operating on radio frequency. Unlike microwave ovens, which use magnetrons, which generate microwaves when an electron stream interacts with a magnetic field, the Freescale oven, or rather, its prototype, uses radio frequency emitters. They are based on technology developed by the company years ago to power cell towers.

RF radiation allows for more precise control of cooking cycles, heat distribution and doneness.

According to the company, such an oven is able to quickly and evenly bring raw or frozen food to the desired condition. In addition, the same emitters are able to determine the degree of readiness of food. And the “radio oven” does not interfere with Wi-Fi, because it operates at much lower frequencies than the 2,4 GHz inherent in microwaves. The company's ambitions include partnering with supermarkets and turning the stove, modestly called Sage - "Sage", into the main node of the "Internet of Things". But for now, it's still a prototype.
