hidden diamond
Rosenberg stood in the corridor, pacing back and forth, feeling hesitant, and after a while, he seemed to have made up his mind.Rosenberg put on his white gloves, opened an oak door, and slipped in quietly.

This is Rosenberg's boss's office.Due to frequent access, he could open every drawer of the desk. He found the key from a brown leather bag, then removed the bookcase, entered a string of passwords, and then used the key to open the hidden safe.

After making sure that no one was around, Rosenberg took out a small black box from the safe, put the three diamonds inside into his pocket, and quickly restored everything to its original state.Finally, Rosenberg checked it carefully and made sure that there were no traces left, so he trotted all the way back to his home.

Once Rosenberg returned home, he began looking for a safe place to hide the diamonds.Finally, he opened the refrigerator, took out the ice maker, filled it with water, put the diamond in the first compartment, and put the ice maker back in the freezer.After the water in the ice box freezes, the diamonds are not easy to find.

After finishing all this, Rosenberg let out a long sigh of relief.He took a shower, then fell into bed and fell asleep.It wasn't until 7 o'clock in the evening that Rosenberg was awakened by a knock on the door.

It was the boss of the company who came in.He kindly said to Rosenberg: "Son, we couldn't find you this afternoon, where did you go?" Rosenberg propped up his body on one arm, and said with a sleepy face: "I have a headache today. , slept in the room all afternoon."

The boss continued: "The diamonds I put in the safe were stolen. Not many people know the password. Do you have any clues?" Rosenberg's heart beat quickly.When he saw the boss staring at the refrigerator, his chest felt stuffy and painful as if he had been hit by a sledgehammer.

"Let me think about it..." Rosenberg stood up calmly and poured two glasses of Coke, then opened the refrigerator, took out the ice maker, put the ice cubes in the first compartment into his glass, and picked another one Ice cubes were placed in the boss's cup, and he pretended to be helpless and said, "I can't think of any valuable clues!"

What is Rosenberg's flaw?
Normal ice cubes will float on the top of the cola, while ice cubes with diamonds will sink to the bottom of the cola glass because of their weight.It was when the boss discovered this that he determined that Rosenberg was the one who stole the diamonds.

Assist in identifying the body
Dr. Ross was entrusted by Police Chief Bank to assist the police in investigating an unidentified dead body case.

It turned out that this unnamed corpse was salvaged from a pond next to F Town, and the corpse was decomposed and unrecognizable.It was midsummer, and the chief of police had to send the body to the crematorium for incineration, leaving only a few photos and a simple autopsy record.Items recovered with the body indicated that the deceased was a local.

Dr. Ross looked carefully at the photos and noticed some distinct black patches on the bones of the man's body.He asked the police chief: "Is there a smelting plant nearby?" After receiving an affirmative answer, Dr. Ross said decisively: "Mr. Chief, you send someone to investigate the area where the smelting plant is located. The deceased was probably in that kind of plant when he was alive." working people."

According to Dr. Rose's instructions, the chief of police found out the name and identity of the unknown corpse in a lead smelting factory, and quickly solved the case using this as a clue.

The black spots on the deceased's skeleton are traces of lead sulfide, which proves that the deceased had been exposed to a large amount of lead-containing dust before his death.Invasion of the lead in the body will form insoluble lead phosphate deposits in the bones.As the unnamed corpse sank at the bottom of the pond, the hydrogen sulfide gas produced by the decay of the pond mud and the corpse reacted chemically with the lead in the bones to form lead sulfide.

Based on this, Dr. Ross concluded that the deceased may be an operator of a heavy metal smelter.

Cleverly discern the direction
Terry is a senior undercover agent of the intelligence agency. He has been hiding in a drug cartel for many years, and finally succeeded in obtaining information that can destroy the drug cartel. But when he wanted to leave, he fell short and was pointed out as an undercover agent. They surrounded him and seized him.

Now Terry is locked in the dark and dank dungeon, his left arm is wounded and painful.Is he going to die here with evidence in his arms?Terry knew that if he didn't run out before dawn tomorrow, he would die.The reason why the drug dealers didn't kill him was because they were waiting for the boss to come back and execute him.

At this time, the little man guarding the dungeon suddenly said to him: "My friend, I can't help you escape, but you can go by yourself. Follow this direction, and go 8 kilometers north to the town, where there is a police station. You You'll be safe there." After speaking, he threw a hacksaw from the window.

"Who are you and why are you helping me?" Terry was surprised and delighted.

"I used to be a peaceful fisherman around here," the little man said with a sigh, "and they put a gun to my head to sell drugs. I deliberately procrastinated, so they let me guard this dungeon. Now, needless to say, you must move quickly, I will change shifts in three hours."

After the little man left, Terry quickly sawed up against the iron bars of the dungeon. After a while, two iron bars were sawed off.Enduring the pain, he bent down and got out of the iron bars, and slipped out of the drug traffickers' camp along the back door of the dungeon.He ran all the way, and he didn't know how long he ran before he stopped panting.

At this time, he found himself in a dense primeval forest without a single ray of sunlight. So, where is the north?If he could not find the north, he would end up starving to death in the forest.

In a distressed mood, Terry searched all over his body, but couldn't find anything that could indicate the direction.There was only a paper clip, a lighter, and a silk handkerchief in my pocket, but they were of no help.

Suddenly, Terry saw a puddle of water on the ground in front of him. With an idea, he immediately made a compass with all the things in his hand, found the direction, and escaped from the forest.

How does Terry's compass work?
Terry snapped off a section of the paper clip and rubbed it vigorously on the silk towel so that the needle became magnetic.Rub the needle twice on the forehead, dip it in a little oil, and put it in the water.

The tension of the oil can make the needle float on the water surface, and the action of the magnetic pole will make the needle point shake. When the shaking stops, the direction indicated by the needle point is north.Of course, there is an error between the North Pole of the magnetic field pointed by the needle point and the geographical North Pole, and the closer the distance is to the Arctic Circle, the greater the error.
