1. Let the distance between Los Angeles and new york be S, and the flight time of birds is s/( 15+20), so the flight distance of birds is s/( 15+20)*30. The answer is 6/7 of the distance from Los Angeles to new york.
2. The maximum probability of putting 1 red balls in one jar and other balls in another jar is1/2+1/2 * (49/99) = 74.7475%.
3. Take out 1, 2, 3 and 4 pills from four cans in turn. Needless to say, the result!
Because the mirror is placed vertically when looking in the mirror, and the mirror is symmetrical, it will not be inverted vertically, but only horizontally. Imagine if the mirror is flat on the floor and people stand on it. Everyone in the mirror is normal, with their heads down and swinging from side to side.
5.3 Wear it for more than one person and think for yourself. How many people have worn it several times?
6. Cut and straighten the big circle. When a small circle revolves around a big circle, it becomes rolling from one end of a straight line to the other. Because the length of the straight line is the circumference of the big circle and twice that of the small circle, the small circle has to roll twice.
But now the small circle rolls along the big circle instead of a straight line, so it also rotates at the same time. When the small circle rolls 1 circle along the big circle and returns to its original starting point, the small circle rotates 1 circle at the same time. When the small circle rolls inside the big circle, the rotation direction is opposite to the rolling direction, so the small circle itself rotates 1 time. When the small circle rolls outside the big circle, the direction of rotation is the same as that of rolling, so the small circle turns three times by itself.
A mathematician's famous saying
1, infinity! No other problem has touched the human mind so deeply.
2. This is a reliable law. When the author of mathematics or philosophy works writes in vague and abstruse words, he is talking nonsense.
Give me five coefficients and I will draw an elephant. Give me six coefficients and the elephant will wag its tail.
Mathematics is the most accurate science, and all its conclusions can be absolutely proved. But this is only because mathematics does not try to draw absolute conclusions. All mathematical truths are relative and conditional.
5. Mathematics is a tool of knowledge and a source of other knowledge tools. All the sciences that study order and measurement are related to mathematics.
6. I have heard that I am an opponent and an enemy of mathematics, but no one respects mathematics more than I do, because it has made achievements that I have never made.
In the world of mathematics, what matters is not what we know, but how we know it.
8, a science, only the successful use of mathematics, can achieve a truly perfect level.
9. As long as a branch of science can ask a lot of questions, it is full of vitality. Without questions, it indicates the termination or decline of independent development.
10, some beautiful theorems in mathematics have such characteristics: it is easy to sum up from facts, but the proof is extremely hidden.
23. Mathematicians are like lovers. Give a mathematician the least principles, and he will come to a conclusion that you must agree with, and he will draw another conclusion from it.
