We will assume that the functions whose graphs we need to build are always located in columns. Moreover, in column a, let there be the values of the variable x, and in columns B, C … the values of the functions f1.f2,… respectively.

Excel has a special chart type called “graph”. With it, you can plot the dependence of data in a column (for example, In) on the line number. Regardless of which category axis labels we set. (Even if the values from column A are signed on the X-axis, the graph will not express the dependence f1(x) in the general [...]

Plotting functions and planes in Microsoft Excel

Microsoft Excel is the leading spreadsheet program. Spreadsheets allow you to process numbers and text, set formulas and functions for automatic execution, forecast a budget based on a scenario, present data in the form of diagrams, publish worksheets on the Internet, etc. In this regard, the computer is one of the means of applying the most important of the principles of learning — visibility. The application of this program forms and develops imaginative, visual, spatial thinking, which facilitates the task of perception, understanding, comprehension and assimilation of educational material.

In my work, I used the Microsoft Excel program to create graphs [...]

The concept of testing

Testing is the language used when writing SMS. Its characteristics:

An abundance of abbreviations (Spocky noki!- good night!)

Disregard for the rules of spelling and punctuation (Che chiba nada)

Highlighting the telephone argot. (Change your SIM card, I’ll use it)

The presence of profanity.(Well, you’re a kazel!!!)

Transmission through words and signs of various emotions (for example, three exclamation marks at the end of a statement convey anger or delight) – (Where the hell are you!!!)

Using numbers to denote a part of a word (to4- exactly)

Linguistic aspects of SMS

Text compression. The volume of SMS is limited, so you need to figure out how to put [...]

History of SMS development

The history of SMS development is very interesting. For 14 years this service remained unclaimed, and then in a short period of time it became almost the main source of additional income for most operators. It all started back in 1991, when the Telecommunications Standards Institute (ETSI) proposed a mechanism for exchanging small blocks of text information between mobile subscriber stations. In December 1992, Vodafone engineer Neil Papworth sent colleagues the world’s first SMS message containing a short congratulations on the upcoming Christmas from his phone. A technology was born that subsequently changed the mobile lives of millions of people [...]

History of SMS messages development

A person’s life does not stand still. The end of the 20th century is a time of scientific and technological revolution, the end product of which is the appearance of a cell phone in our lives. Until now, this necessary item exists, it is unlikely that it will disappear from use or something new will appear, it only continues to improve.

At the end of the 20th century, the availability of communication facilities was high, but there were many places in the world where these facilities were not available to people. For example, two-thirds of the world’s population did not have [...]

Female gamers behave like men in order to be taken seriously 5.5

Today, about half of all computer game lovers are female, but in the public consciousness it is still considered predominantly male entertainment. As a result, female gamers, in order not to be treated down and taken seriously, are forced to demonstrate stereotypically masculine character traits in order to gain recognition from other players.

Computer games have become a mass hobby for people of all genders and ages for many years, but social stereotypes are indestructible: when the word “gamer” most often there is an image of a young guy “stuck” to the monitor. Women are usually credited with a hobby except [...]

“Angry? Bad? Good!”: what is the ethics of artificial intelligence and how it helps to make algorithms useful and safe for people 5.3

How can AI have ethics at all? He’s inanimate! Of course, by itself, it cannot distinguish between good and evil. The task of humanity is not to make AI look like a human, but to teach it to act based on the principles of justice and morality, and not at all as most people usually do. Naked Science answers popular questions about who and why formulates ethical principles for AI, and where and how they are applied.

Ethics is something from philosophy, isn’t it? What is it all about?

Indeed, initially ethics is a philosophical discipline about the norms of behavior towards [...]

Dreams of the spring of artificial intelligence

By the fall of 2022, the editors of Naked Science looked around and decided that it was time to launch a series of articles about artificial intelligence. We start with a large article, the subtitle of which could be the phrase “a brief introduction to the history of AI — from medieval monks to deep learning.”

Artificial intelligence (AI) — almost everyone knows these two words, but few people can give a clear definition and explain what it is. Our ideas about AI are formed more by Hollywood cinema than by a real understanding of the technologies behind this word. Cinema, [...]

“Non-elementary bitumen”: will the participants of the IT competition be able to come up with a solution that will help influence the construction of high-quality roads? 5.5

“Gazpromneft – Bitumen Materials” together with ITMO University with the support of the Digital Downstream Accelerator from Gazprom Neft will hold an IT competition for programmers. The purpose of the hackathon is to develop a mathematical model for predicting the quality of a component (namely a high—tech binder) for the construction of Russian roads.

Gazpromneft — Bituminous Materials, being the technological leader of the industry, cannot but focus on the expansion of IT technologies for automation and digitalization of operational processes. In addition, it is important for such enterprises to continuously improve the quality of products — hence the idea of [...]

The android was taught a sense of humor 5.5

Japanese scientists have developed an artificial intelligence system for the android Erica, which allows her to react naturally to the laughter of the interlocutor. Now Erica can not only recognize a person’s laughter, but also determine whether she should laugh in response and what type of laughter to use for this.

Scientists from Kyoto University (Japan) have developed an artificial intelligence system that allowed the Japanese android robot Erica to respond appropriately to the laughter of the interlocutor. At the same time, scientists did not seek to make Erica detect laughter or respond to a joke, but tried to endow artificial [...]
