Introduction.
Hello dear readers!
From now on I will keep in the newspaper section "TRYNDETS.
By title you probably guessed what zde will be discussed. Well
if you have not guessed, then read on ...
Reading my section, you will get a lot of useful and
interesting information that you might need in life. In it I
will write about a variety of things, interesting logic
problems and any other utility.
If the readers will be interested in this category, it will
become permanent, but if you treat her indifferently, then I
think that it unfortunately will have to close. But I very much
hope that it is pleasant to you, and you give ME to die a new
idea.

Let's start ...
First, some interesting problems:
01. Three wise men
Three wise men, was very tired lay down to rest under a tree,
and while they were sleeping, some hooligans stained their
faces with charcoal. Prosnuvshis and looked at each other they
began to laugh, and no one is not worried because everyone
seemed to laugh with each other two over another. Suddenly, one
of the sages longer laugh, because he realized that his
forehead sobsvenny also stained. Q: How did he argue?
02. Puzzle
What should be put between the number of written numerals 2 and
3 to get a number greater than two, but three menfee?
03. What's the name the driver?
The train ride from Moscow to Leningrad passengers Ivanov,
Petrov and Sidorov. The same names are the engineer, fireman
and conductor of the train crew. It is known that: 1) A
passenger Ivan lives in Moscow 2) The guard lives halfway
between Moscow and Leningrad 3) Passengers, namesake of the
conductor, living in Leningrad 4) One passenger, who lives
near the residence
conductor than other passengers, earns
month, exactly three times the conductor
5) Passenger Petrov earns in a month of 2000 rubles
6) Ford (of teams) has recently won a fireman
Party billiards.
Q: What's the name the driver?
ANSWERS TO PROBLEMS IN SEARCH FOR THE NEXT ISSUE.
I think the reader will be interested to know how fast
move some of the animals:
snail 1.5 mm / s 5,5 m / h
Turtle 20 mm / sec 70 m / h
fish 1 m / sec 3.5 km / h
pedestrian 1.5 m / s 5 km / h
fly 5 m / s 18 km / h.
Hare 18 m / s 65 km / h
Eagle 24 m / s 86 km / h.
And for comparison:
sound in air 330 m / s 1200 km / h.
bullet √ 850 m / sec
Among the readers of course there are those who interisuyutsya
cars, but not everyone knows the following: In 1986, the road
race between Paris and Brest was achieved speed 20km/chas, ie 6
m / sekendu. This was considered in While the car a great
triumph. But aerez year vehicle speed has been doubled, and in
1907 avotomobili develop speed in five bolyushu - 30 m / sec,
or 108 km / hr. To make a clearer idea of this speed - 30 m /
sec, we observe that stone thrown because of all the forces of
flies for a second pervu half - 15 m. The competition cars in
1923 reach speeds of 219 km / hour in 1929 was achieved
unprecedented rate (at that time something!) at 370 km / h, ie
100 m / s Yet, this rate is not the limit. In 1932, the race
car reached the speed of 435 km / h!
Unscathed.
Put a coin on the big Polski plate, and pour so much
water so that it covered the coin, and ask someone to take
her not to wet Fingers. This seemingly impossible task, quite
simply solved by using glass and burning paper: light a piece
of paper, put it inside the glass and the glass quickly put on
a plate near the coin, BOTTOM TO TOP. Piece of paper will go
out and cup filled with white smoke and then the water itself
ssoboy meet with plates in a glass! Coin naturally remain in
place, and a minute later when she obsohnet, you can safely
take it, without wetting your fingers! And why is this
happening, try to guess for yourself! P.S. I note that the
piece of paper should be such that when you turn the cup (with
a burning piece of paper inside), it should not completely wet,
goryaschayaya part, must be dry. If someone not clear that
experience, I advise you to read a book "Entertaining physics,
or at worst - give me a call. Personally, I have this
experience has turned out the second time since I first read
the bad text.
And just in case:
The smallest interval of time, small date
can be measured: 10 000 000 000th of a second!
Oktyabrskaya Railway in the summer at 300 meters longer than the
winter!
Telephone line from Moscow to Leningrad in the winter for five
hundred meters shorter than in the winter!
Elib there was no atmosphere, it bullet flew to her instead of
Of Proposition four miles - for forty miles!
Radius of the globe: 6371000 meters.
The snail moves a thousand times slower than a man!
Well, I think that is enough for today. See you next time!
