Introduction.

There is no exact date for the birth of mathematics, it is only known that it appeared before our era. Mathematics is not classified as a natural science, but it is fundamental. It is used in almost all spheres of human life. The development of mathematics began along with the fact that a person began to use the numbers two apples and two oranges, despite all their differences, have something in common, namely, they occupy both hands of one person - a qualitative achievement of human thinking. People began to use numbers to calculate time, days, months, the number of certain items, etc. After some time, knowledge of mathematics filled our world and was used in various activities, primarily in trade, construction, and the production of various items, including weapons.

In the modern world, mathematics is very necessary, because we are surrounded on all sides by computers and numbers.

With the help of mathematics, you can analyze texts, extract information and find meaning.

A high level of development of mathematics is necessary for the progress of many sciences. It is difficult to find a field of knowledge where mathematics would not play any role.

Military mathematics, that is, mathematics adapted to military needs, already existed among the Babylonians. Many sections of modern mathematics have also been developed from military tasks.

The ancient Greek scientist - Archimedes made many discoveries not only in mathematics and other sciences, but also showed how it is used for military purposes.

“Mathematics is the gymnastics of the mind,” said the great commander Suvorov.

“Mathematics is just why it is necessary to teach, that it puts the mind in order” - these are the words of our famous and brilliant Lomonosov.

Based on the foregoing, we have chosen a topic for writing the project "Military Mathematics"

We have set ourselves the goal of:

1. Development of interest in mathematics.

2. Development of attention, logic, thinking.

3. Familiarization with the use of mathematics in military affairs.

Stages of work:

1.Choose a theme

2. Search for information

3. Analysis of the collected material

4. Evaluation of the work done

Project objectives:

Acquaintance with the problems of mathematics used in military affairs.

Great mathematicians.

Attempts to apply mathematics in military affairs are found in ancient times. In the military-theoretical works of Xenophon (Greece), Polybius, Vegepius (Rome), Sun Tzu (China), there are elements of a quantitative approach to the analysis of certain issues of military affairs. A significant contribution to the development of mathematics was made by the ancient Greek scientist Archimedes (about 287 - 212 BC), whose knowledge of mechanics, physics, and military affairs was combined with the use of mathematics to solve practical problems. The use of mathematics in ballistics was first described in the books of the Italian N. Tartaglia "New Science" (1537), "Questions and Discoveries Related to Artillery Shooting" (1546).

In the late 18th - early 19th century, in connection with the increase in production and improvement of weapons for mass regulatory armies and navies, the widespread use of mathematical methods in the field of design, research and production of weapons began.

A. N. Krylov successfully applied the mathematical apparatus in the theory of shipbuilding, as well as to calculate the longitudinal oscillations of the barrel of an artillery gun when fired.

The application of mathematics in aerodynamics, which originated in connection with the needs of aviation in the early 20th century, ensured the development of scientific theory and the creation of methods for calculating the wing lift.

During the Great Patriotic War, Soviet mathematicians made a great contribution to the development of military equipment. Thanks to the work of M. V. Keldysh, M. A. Lavrentiev, and later A. A. Dorodnitsin, topical problems of theoretical and experimental aerodynamics were solved, which played an important role in the development of military jet aviation. The works of A. N. Kolmogorov on the application of mathematical methods in the theory of shooting are widely known. A group of researchers led by S. A. Khristianovich, on the basis of mathematical calculations, carried out work to increase the accuracy of powder rockets.

The Leningrad Institute of Physics and Technology was entrusted with developing methods for protecting ships from mine and torpedo weapons. The idea of ​​demagnetization was proposed and implemented by scientists led by Academician A.P. Aleksandrov, the Saami having rendered great assistance to the Naval Forces.

Works by V.V. Golubev on the theory of vortex formation behind a body streamlined in a stream, for example, a wing or fuselage of an aircraft, helped develop measures to bring the aircraft out of the "corkscrew" state.

Andrei Nikolaevich Kolmogorov solved the problem of increasing the effectiveness of artillery fire. Probability theory was used to locate enemy aircraft and submarines, to indicate routes to avoid enemy submarines.

M.V. Keldyshev and a group of scientists solved the problem - the destruction of aircraft due to vibration. The complex mathematical theory of flutter provided the aircraft with reliable protection against the appearance of vibrations.

The history and current state of the application of mathematics in military affairs show that the connection between military science and the practical activities of the armed forces and mathematics is an objective process continuously developing in time. The number of military tasks solved with the help of mathematical methods and means of automation, especially in the field of forecasting the development of military science, military equipment and weapons, as well as in the development of solutions, is constantly growing.

Mathematics for military purposes.

Mathematics is one of the powerful tools for understanding and using the laws of armed struggle in the theory and practice of military affairs. Mathematics can ensure the further deep development of military affairs. Mathematics makes it possible to analyze in detail the essence of the processes of armed struggle, to identify its quantitative patterns and, consequently, to find optimal solutions and options for combat operations.

The effective use of mathematics in the field of military art has become possible thanks to the use of electronic and computing machines capable of solving complex and time-consuming problems associated with finding optimal solutions in a short time.

The point of using mathematical methods in the processes of command and control of combat operations of troops is to use knowledge of the laws, regularities and principles of armed struggle to reduce the time for preparing decisions and improve their quality, to achieve the best results of combat operations with the available forces and means. The use of mathematical methods in combination with electronic computers makes it possible to solve problems of this kind, providing a sufficiently fast and reliable forecast of the course of hostilities for analyzing any possible solutions.

Mathematics in modern conditions plays a very important role in the study of armed struggle and the use of identified dependencies and patterns that manifest their effect through the principles of military art.

Mathematics makes it possible to take into account and implement these principles most fully by developing quantitative recommendations based on the specific real conditions of combat reality. This is where the possibilities of mathematics lie, since the analysis and accounting for specific quantitative changes can lead to qualitative changes.

Military art is the focus of combat experience accumulated over many centuries. To identify and establish the patterns of armed struggle, it was necessary to study and analyze the centuries-old experience of warfare.

Before the advent of electronic computers and combat simulation methods, this was the only correct way. There were no other ways. However, as applied mathematics develops, the situation changes.

Mathematics makes it possible to simulate combat operations, and, consequently, to reveal the main connections in the processes of conducting armed struggle. In other words, mathematics makes it possible to reveal and establish the patterns of armed struggle by using electronic computers and building various models.

Combat simulation is an excellent tool in the hands of military leaders to predict the possible outcomes of hostilities. If the simulation of combat operations is a universal method, then other mathematical methods provide ample opportunities for solving particular problems when implementing the principles of military art.

The use of various methods for optimizing the combat operations of one's own troops is precisely the essence of the application of mathematics in military affairs.

The task of mathematics is to take into account quantitative changes most accurately. Consequently, mathematics and computers give commanders of all ranks the opportunity to link the main philosophical categories: quantity, measure and quality, and thus become in the hands of the commander the most important weapon designed to help him achieve success in solving assigned tasks.

Entertaining tasks.

1. Crossing problem.

A small detachment of soldiers approached the river, on the banks of which there was a small boat and two boys. How, with the help of boys and a boat, did the detachment cross over to the other side, if one soldier or two boys can sit in the boat?

Solution.

2 boys swim first. One remains on the other side, and the second returns and the soldier crosses. Then the boy from the opposite shore swims back to the detachment and takes his comrade, who, in turn, returns again and the second soldier crosses, etc.

1. Three battalions problem.

During the offensive operation, the brigade of soldiers was divided into three battalions: the first battalion consisted of 450 fighters, the other 130 fighters less, and in the third battalion there were 2 times fewer soldiers than in the first and second combined. What is the total size of a brigade of soldiers?

Solution.

450 - 130 = 320 - people in the 2nd battalion.

450 + 320 = 385 - people in the 3rd battalion.

450 + 320 + 385 = 1155 - total people in the brigade.

Answer: 1155 people.

1. Task "Bridge over the river".

Two military units located on the same bank of the river at different distances from it urgently need to cross one bridge to the other side of the river. Where should the temporary bridge be built so that it is at the same distance from the military units?

Solution.

On the median perpendicular to the segment connecting the two military units.

1. In besieged Leningrad, children under 12 were given 150 g of meat for 10 days, and a worker - 2 times more. How many grams of meat did a worker get for 10 days?

1. The maximum speed of the Soviet wartime fighter Yak-3 is 720 km / h, the German fighter Messerschmidt - 109 is 120 km / h less than the speed of the Yak-3 and 30 km / h more than the speed of another Focke-Wulf 190 fighter -BUT". Find the speed of the German fighters and compare them with the speed of the Yak-3.

1. The maximum speed of the T-34 tank, which was the best in the world during the war years, is 55 km/h, and the speed of a fascist tank of the same class T-III is 40 km/h. Will our tanks manage to capture the crossing if, according to intelligence, the fascist tanks are at a distance of 20 km from it, and ours - 24 km? At the same time, it must be taken into account that on the path of Soviet tanks there is an impassable section 4 km long, which can only be overcome at a speed of 30 km / h.

1. The reconnaissance officer, moving as part of the squadron, was given the task of surveying the sea area for 70 miles in the direction of the squadron's movement. The speed of the squadron is 35 miles per hour, the speed of the scout is 70 miles per hour. It is required to determine how long the scout will return to the squadron.

1. The Great Patriotic War began on June 22, 1941. An amazing square will help you find out how many days the war lasted. Choose one number from each row and each column, find the sum of the selected four numbers, and you will get the answer to the question.

413 218 474 567

569 374 630 979

195 0 256 349

221 26 282 375

10. Great hopes in the war were placed on tanks. For the crossing of 80 tanks across a river 720 m wide, there is one crossing facility. The duration of one flight of the ferry vehicle is 15 minutes, the ferry vehicle returns empty in 5 minutes, two tanks are simultaneously transported. The time of loading and unloading tanks from the ferry facility is taken into account. To reduce the time of tank crossing, part of the tanks can be transported under water along one route (figure). The speed of movement of tanks under water is 72 m / min. Determine the time for the tanks to cross the river.

11. The partisan detachment, located in the Smolensk forests, must transfer part of the ammunition to the partisans from near Minsk. What path must the partisans of Smolensk overcome if the distance on the map, the scale of which is 1:25000000, is 2 cm?

Conclusion.

There are many situations in life where the application of mathematical knowledge is required. Not only for military purposes, but also for other professions. There are still quite a few mathematicians of antiquity, which proves the importance of this science.

Mathematics makes us think, analyze. There are no lies in mathematics. All formulas and proofs have a rigorous proof. Mathematics develops the ability to think logically, which allows a person to live interestingly and never be bored.

The conclusion from this can be drawn as follows: the development of human intellect is necessary for the development of civilization.

Like an air,

Math is needed

Courage alone is not enough for an officer,

Calculations! Volley!

And the target is hit

Mighty blows of metal...

Literature.

Building

There are two teams participating in the competition. At the command of the toastmaster, they must line up by height, by age, by foot size, by the number of buttons on clothes, by name (in alphabetical order). After each construction, the toastmaster checks its correctness. A point is given to the team that completed the task faster without errors. The team with the most points wins.

Relay "February 23"

Two teams participate in the relay race (more possible). Each team is given Chinese sticks and a tray on a chair. Opposite each team put a chair with a plate of peanuts. At the command of the toastmaster, the first participant runs to the chair, takes the nut with chopsticks and runs back to the team with it, puts the nut on the tray so as to write the number 23 with the nuts.

Then the sticks are taken by the next member of the team, who runs after the next nut. If the nut falls, then the player returns to the plate for another nut. The first team to place the number 23 on the tray wins.

Drill

Tamada gives commands (to the right, to the left, around, equal). Participants must quickly and correctly perform them. Whoever makes a mistake is out. The pace of the teams is gradually increasing. The winner is the participant who never makes a mistake.

Army ranks

There are two teams participating in the competition. Tamada distributes cards with army ranks to both teams (one card for each player). It is necessary to line up in order of rank (private, corporal, junior sergeant, sergeant, senior sergeant, foreman, warrant officer, senior warrant officer, junior lieutenant, lieutenant, senior lieutenant, captain, major, lieutenant colonel, colonel, major general, lieutenant general, general Colonel, General of the Army, Marshal of the Russian Federation).

Shoulder straps

Several men participate in the competition (preferably those who served in the army). The toastmaster gives each participant a set of cards with the image of shoulder straps. Some of the images are correct, honor is not. It is necessary to choose the right shoulder straps. The winner is the player who completes the task faster than others without errors.

Running in uniform

Two or three teams participate in the competition. The toastmaster gives epaulettes to each team. The first participant puts them on his shoulders and runs a certain distance with them. Then he passes the shoulder straps to the next participant. So all the players of the team must run once. You cannot hold shoulder straps with your hands. If shoulder straps fall, they must be picked up, put on the shoulders, hands removed, and then run on. The fastest team wins.

Troop insignia

Several people are participating in the competition. The toastmaster demonstrates to the participants the images of the insignia of the troops. Participants must correctly name the army to which it belongs.

Emblem of the Air Force

wounded soldier

Several couples are participating in the competition. Men will play the role of a wounded soldier, women - nurses. According to the scenario, the soldier was wounded in the leg. It is necessary to bandage the leg with a bandage (toilet paper), wrapping the entire roll around it (the soldier is sitting on a chair).

Then you need to help the soldier get to the hospital (to a conditional place). At the same time, the soldier cannot step on the foot (he must lean on the nurse). The first couple to arrive at the hospital wins.

Get ready - sing!

Several men are participating in the competition. Each toastmaster gives out a toy gun, a screwdriver, batteries (in the amount necessary for the operation of the gun). It is necessary to charge pistols with cartridges (batteries) at speed. To do this, you must first unscrew the bolt of the cap that closes the battery compartment, insert the batteries and tighten the cap with the bolt.

Whoever did all this, signals this by pressing the trigger (the gun should make a beep). The toastmaster checks the quality of the work (how the bolt is screwed). The one who completes the task first wins.

Strategist

There are two people in the competition. In front of them, the toastmaster pours a box of matches on the table. Players take turns taking 1, 2 or 3 matches (how many to take, the player decides) at a time until one match remains. The player who takes the last match loses.

Cryptographer

Each player is given a message encrypted in Morse code (dot-dash) and the Morse code itself. The message needs to be decoded. Whoever does it first wins.

Suitable scenarios for the holiday:

• Toastmaster: Hard in teaching, easy in battle, Men are taught this way in the army, preparing ...

To keep the mind sharp, it needs training. And for this, tricky puzzles will always come to the rescue. We have prepared for you 10 Soviet riddles of varying complexity: some are quite simple, some are more difficult, and some will have to seriously break the brain. All tasks will be in pictures and will require attention and logic from you. These puzzles come straight from the USSR, but still have not lost their relevance and intricacy. Postpone everything: now your brain will have a full charge.

1. Let's start with a warm-up, it's easy. So take a look at the picture

The children went out into the forest to go ice skating and skiing. A hare jumped out to meet them, sat down in fear and rushed on. The guys chased after him, but lost sight of him. But the hare did not run away, he is still in the picture. Find?

Yes, here he is! Between boy and girl

2. Now it's more difficult. Meeting on the street

2 friends met on the street:
- Hello, Styopa. Where are you going?
“I’m going to house number 23,” Styopa says. — Where are you, Petya?
- And I - to my friend Vanyusha. He lives in house number 7, - Petya answers.
Now tell me: which of them is called Styopa, and which is Petya.

Styopa is a boy in a cap. Why? Pay attention to the house number - 19. If you go from the first house on the street, then the houses with odd numbers will be on the left side, the boy in the cap moves towards the houses with large numbers, 23 is more than 19, which means that this is Styopa.

3. Whose Murzik?

There are three girlfriends in the picture: Ira, Tanya and Galya. The cat Murzik is with them. But whose is he? Who is Murzik's mistress?

Murzik belongs to Galya, a girl with one bow. She gave the second to Murzik.

4. Names of children

There are five children in the picture. One of them is called Kolya, and he is standing on the edge. If Nyura stood next to Volodya, then Petya would be next to his namesake. Who is standing where?

So, in order: Kolya, Volodya, Petya, Nyura, Petya.

5. Riddle about watering cans

The boys went with watering cans for water to water the garden. Which one will bring more water?

Despite the fact that one of the boys has a larger watering can, their spouts are located at the same level, above which the water in the watering can does not rise (recall physics and the law of communicating vessels). So they will bring the same amount of water.

6. Where is the train going?

In the figure you see a section of the Moscow-Smolensk railway. Here the direction of the road coincides with the direction of the arrow shown above, the ends of the arrow pointing west and east. Everything happens at the beginning of April. Where does the train go: from Moscow to Smolensk or vice versa?

The snow has not melted yet, it lies on the northern slope, which means the train is moving from east to west. It turns out that from Moscow to Smolensk.

7. And now let's look for errors and inaccuracies in the picture

The artist drew a street, but here's the bad luck: he made 5 mistakes in the drawing. Can you find?

1. The trolleybus is missing one rod.
2. A traffic light has 2 lights, but it should have 3.
3. The house number is also wrong - there are no zero houses.
4. Cars are not driving in the same direction as when driving on the left. And we are on the right side.
5. Well, the date - September 31 cannot be.

8. Travel mystery is probably the most popular on the Internet

Look at this picture and answer the questions:

1. How many people currently live in this camp?
2. When did they arrive (today or a few days ago)?
3. How did the tourists come?
4. How far is the camp from the nearest settlement?
5. Where does the wind blow: from the south or from the north?
6. What time of day is shown?
7. Where did Shura go?
8. Who was on duty yesterday (name)?
9. What date is shown (day, month)?

1. 4 people. 4 cutlery, 4 names on duty list.
2. A few days ago, a cobweb had already appeared between the tent and the tree.
3. On the boat. See the oars near the tree?
4. Near. There is a chicken in the lower left corner, which means that some settlement is nearby.
5. The wind blows from the south. We determine by the flag on the tent and spruce branches, where they are thicker, there is south.
6. Morning. We have already understood where the south is, which means that we will also find the rest of the world. Shadows from objects fall to the west, which means the sun is in the east. And this is morning.
7. Shura catches butterflies with a net.
8. Kolya. He is digging in the backpack with the letter “K”, Vasya is taking pictures of something (a tripod is visible in the backpack with the letter “B”), Shura is catching butterflies, which means that Petya is on duty today. And yesterday Kolya (look at the duty schedule).
9. 8 August. 8 - because Petya is on duty, August - because the watermelon is lying.

9. Riddle about a boy and dad in the apartment

1. What season is in the picture?
2. What month?
3. Does the apartment have running water?
4. Who else lives in the apartment, except for the son and father?
5. What is dad's job?

1. Winter. A boy in felt boots, the stove is heated (the air vent is open)
2. December. The last page of the calendar is open.
3. The boy uses the washstand, which means there is no running water.
4. There are dolls in the picture, which means that there is a girl in the apartment, most likely of preschool age.
5. Doctor. A hammer on the table and a phonendoscope in his pocket.

10. Crossing (but this is already difficult)

1. Is this picture late fall or early spring?
2. Do cranes fly north or south?
3. What time of day does it all happen?
4. Is this river navigable?
5. In what direction does it flow (north, south, west, east)?
6. Is the river deep near the shore where the boat is standing?
7. Is there a bridge nearby?
8. Is the railroad far?

1. Early spring. There is sowing in the field. Autumn sowing occurs when there are leaves on the trees, but in the picture the trees are bare. So it's early spring.
2. In spring, cranes fly from south to north.
3. Early in the morning, people rush to work, shadows fall to the northwest.
4. There are buoys on the river (devices that look like buoys), which means that the river is navigable.
5. Looking at the shadows from the objects and how the water goes around the buoy, we conclude that the river flows from north to south.
6. The boy is fishing on the shore, his float is far enough from the hook, which means that the river is deep.
7. If the crossing is so well established, then there is no bridge.
8. At the crossing there is a railwayman, which means that it is not far.

And bonus, it's very easy. What is the purpose of this poster?

For Kolya to go out into the yard, obviously! And if it's not obvious, read the letters!
