Cohabitation with the police flower: the student against the sky

The old professor was taken aback by Ling Jie's words, there are still people who want to join SC these days, silly!

However, the old professor just had this thought in his heart and didn't dare to say it out.

After all, now that he wanted Ling Jie, how could he be so stupid as to scold Ling Jie.

"Okay, since you're not interested, I can't help but force it! Come here and help me with this question! If you can help me solve it, I will thank you very much." The old professor greeted Ling Jie to the desk go.

Ling Jie nodded and followed behind him.

The wisdom of this old professor is well known in CUHK.

Even he can't answer it, presumably this question should be difficult!

……

Walking to the seat, he sat down, opened a document, and said, "This is the question, please help me solve it!"

Afterwards, the old professor made room for Ling Jie.

After Ling Jie sat down, he frowned and looked at the question in the document.

This question, the topic is very simple.That is to say, if you squeeze hard, how can you protect the egg in your hand from being crushed.This problem may seem common, but it is very difficult to practice.Eggs are pinched in the hand, as long as they are gently pinched, they will generally break.Not to mention, I squeezed it hard with my hands.

In other words, facing such a quiz, Ling Jie was also very puzzled, which bastard was the one who came up with the quiz.

Everyone knows that this egg will crack if you put it in your hand and squeeze it lightly.Moreover, there cannot be any objects outside the egg.

……

Seeing Ling Jie frowning silently, the old professor was also very depressed. This question has troubled him for a long time.The eggs at home have been crushed a hundred times, but I still can't find a way.

……

"This egg can't be covered with something, right?" Ling Jie asked.

"Yes!" said the old professor.

"I thought of a way! In this way, you put the whole egg in the pot and boil it until it is 5 minutes cooked. Then, you immediately fish it out. Put it in the freezer of the refrigerator and freeze it for about 5 minutes! In this way, you can Also, there is nothing on the egg, no ice flakes. I promise, if you pinch it vigorously at this time, it will definitely not crack...!" Ling Jie said excitedly.

Ling Jie still understands the principle of thermal expansion and cold contraction.

The eggs are in the pot. During the 5 portions of cooking, the eggshells have gradually absorbed the high temperature outside the eggshells.At this time, remove the eggs, put them in the refrigerator, and freeze for 5 minutes!

That is, keep this heat rise temperature inside the eggshell!

However, the resulting layers of resistance are thinner.

In fact, this is not really resistance.It's just that the strength of the palm is dispersed according to the temperature of the heat rise!In this way, it is possible that the eggs will not break quickly.

However, Ling Jie has never tried this experiment, he guessed it.

Logically speaking, it should be fine.

However, this is still a bit difficult to implement.

First, the medium-rare heat should be kept well.Second, the freshly cooked eggs should not take more than 2 seconds to arrive in the refrigerator.The principle is to seize the time within these two seconds.Otherwise, the effect should not reach the theoretical result.

Hearing Ling Jie's words, the old professor frowned and pondered for a moment, and said, "What do you mean, using the invisible power produced by the sudden encounter of heat with ice? Is that the case? And, the most important thing is to get the eggs out of the pan." During the time in the refrigerator? Ling Jie, why did you think of this? This method, I think it should be possible...!"
