The science and technology of human civilization can develop so fast that it can go out of the earth and explore the universe by leaps and bounds in a short hundred years. These achievements are inseparable from the contribution of scientists to human beings. In order to praise and reward scientists who have made contributions to mankind, the Nobel Prize appeared. There are many categories of Nobel Prize, such as economics prize, physics prize, chemistry prize and so on.
In fact, there is a special category of Nobel Prize, that is, the funny Nobel Prize. Many people may not have heard of this award and do not understand how to choose this funny Nobel Prize? The so-called funny Nobel Prize is actually to select the kind of research that “makes people laugh at first sight, and then makes people think deeply”. Therefore, those who can win this prize are often some senior physicists. Many of them have won physics prizes and some previous Nobel Prize winners.
There is no limit to this award. As long as your research can meet the requirements of “making people laugh at first sight, making people think deeply afterwards”, you may win the funny Nobel Prize. What we want to share with you today is the story of someone who won a funny Nobel Prize because of a deep thought caused by noodles.
I don’t know if my friends have ever done such a seemingly chatty thing in their daily life: folding noodles means folding noodles from both ends inward. Of course, it must be raw noodles. It is estimated that no one will be bored to fold noodles, and Xiaobian has never done so. If you’ve ever tried to fold spaghetti, you’ll find a very interesting thing, that is, you can’t fold the spaghetti into two parts. No matter how hard you try, you’ll get a lot of breaks in the end.
The biography written by the famous physicist Feynman once recorded such a thing: one night, Feynman felt very bored, so he began to fold spaghetti, but Feynman found that no matter how to fold, suddenly or slowly, he could not fold the spaghetti into two parts, because when the spaghetti was about to be broken, it would break from the middle, so it was often broken When Dali was broken, it became three or more pieces, but it couldn’t be broken into two pieces. Feynman tried all night, but failed.
Is this a magic thing? Why can’t spaghetti break in two? If ordinary people look at it, they will smile: what’s so strange? Spaghetti itself can’t be broken in two. Few people will think about some of the scientific reasons and find out how to break spaghetti in two. A lot of scientific reasons come from daily life. For example, Newton sat under a tree and thought when he saw the falling apple. Finally, he put forward the law of gravity.
We ordinary people naturally don’t care about why spaghetti can’t be broken into two parts. For some researchers, there are many people who are interested in it. In 2005, a French research team continued to study the experiment of Freeman’s breaking spaghetti. In the process of research on Italy, the research team found the problem.
When the strip is bent from both ends, it will break near the middle part. The initial fracture will cause a kind of “rebound” effect and a kind of bending wave or vibration, which will further damage the object and make it break further. The discovery revealed why spaghetti couldn’t be broken into two parts, and the French scientific team won the 2006 Ig Nobel Prize.
The key to the problem is how to break the spaghetti into two parts? After many experiments, mathematicians at Massachusetts Institute of technology in the United States finally found a method, and published the research results in the journal Proceedings of the National Academy of Sciences. The method is to twist the spaghetti as much as possible, and when the two sections are folded in half, it can be folded in half.
And this twisted spaghetti angle is 270 degrees. When the spaghetti is twisted 270 degrees and then bent, the spaghetti will break into two parts. This phenomenon actually stems from two kinds of effects: rebound effect (because of the twisting effect, the rebound effect in the opposite direction is reduced when bending), reverse torsion effect (when twisting, the spaghetti wants to return to the original straight state, This releases part of the energy and prevents further fracture).
From the above example, we can see that science comes from our daily life. In our daily life, there are many things that we think are very normal and take for granted. But these ordinary things often contain profound scientific truth, and even contain the truth of the world and the truth of the universe.
Science comes from life. As long as you carefully observe everything in daily life, you will find many things that can not be explained by modern science. As long as you can crack any one of them, you will not only make great contributions to the progress of human civilization, but also have the chance to win the Nobel prize. Of course, to crack these, you need to work hard to learn scientific knowledge, only in your brain Rich scientific knowledge, you can uncover the truth, otherwise, even if you encounter such a situation as apple landing, you will not discover the law of gravity like Newton.
