In the history of the earth, the first thermometer was invented by Galileo Galilei using the principle of thermal expansion and contraction of water. It's just that the accuracy is very poor, and the practicality is not good. Later, after the modification of Galileo's friend Sanctorius, thermometers appeared in the sixteenth century.

However, the real practicality of the thermometer has taken almost 300 years, from water to alcohol to mercury and other materials to continue to experiment, to find the most suitable material, which is also the process of continuous exploration by science.

Although the thermometer looks ordinary, it is very practical, for example, Duke fired porcelain before, if there is a galvanic thermometer, there is no need for a fire magician to control the temperature.

Of course, Duke didn't want to make a couple thermometer this time, which is too much ahead of history, and Duke himself has no ability to do it. He approached Galileo just to create the most basic thermometer, which was the most convenient and basic medical tool for screening and determining the disease.

After making sure that the history of the development of the world's thermometers has not changed, Duke said with a slight smile on his face: "I have only heard about it, and I don't know everything." Galileo, I think this temperature measurement tool you invented is very valuable, for example, if you can accurately measure the temperature, then we can know the coldest time and predict the possible attack of the ice demon in advance. Moreover, this epidemic can also judge whether the temperature of the human body is normal, and the abnormal high temperature and fever may be contaminated with disease, so isolate in advance and so on. ”

Duke's words seemed to open the door to a new world for Galileo, he never thought that a thermometer that was just an experimental specimen would be so useful, and Stormcastle could be used directly.

But when he thought of the actual situation of the thermometer at present, Galileo immediately said with a frustrated expression: "My lord, I also hope that the thermometer I invented will one day be able to achieve the uses you mentioned. But now the thermometer is just a very rudimentary instrument, and the accuracy and practicality are very poor, which may disappoint you. ”

In Galileo's case, Duke certainly knew that almost three hundred years had passed between invention and application. Duke must not have been able to wait for 300 years, as a prophet of history, he knows that in fact, the working principle of the thermometer has not changed, it is nothing more than the change of the temperature measuring material inside.

It's like the story of Edison's invention of the electric light, which went through more than a thousand experiments, and finally solved two problems were vacuum and carbon filament. The same is true for thermometers, the final solution is sealing and mercury, as long as these two principles are known, the difficulty of manufacturing thermometers is still much lower than that of electric lights.

Duke did not hide it, and used a reminder to tell Galileo these two key points. But Galileo's face was full of doubt, he didn't know how Duke knew this, and he didn't know if what Duke said really worked.

However, it is up to Galileo to solve these things, after all, the biggest difference between Duke and the scientific pioneers of this world is that he knows the final result and even the principle, but he is not proficient in the process. Therefore, he can give a god-like guidance, but the final experimental process and success still need to be completed by the people of this era.

"My lord, I am angry and ask, how the hell do you know these things?"

In the end, Galileo did not suppress his inner curiosity, which may also be the common thinking of the pioneers of experimental science, curiosity is the driving force behind scientific progress.

In the face of Galileo's question, Duke said earnestly: "Galileo, do you remember a word I once said to you? This is science! Everything I know is taught by science, and the unknown and knowledge you are exploring now are also science, and one day you will carry forward the truth of science." ”

After saying this, Duke patted Galileo on the shoulder, and then turned around to leave him with a majestic back, quite uninhibited with deep merit and fame!

Galileo looked at Duke's back and kept repeating the word in his mouth. Slowly, his eyes began to burn, and he seemed to understand the meaning of the word.

That's right, the right truth I'm looking for is science!

After dealing with Galileo and their affairs, Duke returned to his side hall physically and mentally exhausted, what has happened in the past few days, it can be said that he has used his life's energy, he didn't expect that he really has a talent to be a lord, and sure enough, people are forced out.

Not long after Duke sat down, the maid Sophia came forward with food, and Duke, who was originally a nobleman, usually dined elegantly in the dining room in accordance with the aristocratic way. As a result, after all kinds of busyness, Duke doesn't even have time to go to the restaurant to eat seriously.

But then again, in the Middle Ages, many of these dark dishes have nothing to do with enjoying food, and eating is no longer for life, but more for survival, so it doesn't matter where you eat it......

Seeing Duke's tired face, Sophia did not choose to leave after putting down the food, but stood behind him and watched Duke's back. In the past few days, Duke has been busy with territorial affairs, and Sophia has seen it, which makes her impression of Duke completely reversed.

Is this still the same gentleman who only eats, drinks and has fun, and thinks about molesting the castle maid?

Especially the epidemic prevention operation that has just been launched, Sophia is even more grateful to this new lord from the bottom of her heart. In the past, when it came to winter like this, the previous lords didn't care about the lives of the civilians, because they had no intention of staying in such a dangerous territory for long.

Therefore, even if it is isolation, it is not the isolation of the sick from the ordinary people, but the isolation of the aristocratic class, including the lords, from the commoners. It can be said that for the civilians of Stormcastle, the direct casualties caused by the Ice Demon are far less than the cold and plague of winter. After all, the Ice Demon doesn't attack every year, and the number of times they have breached Storm Castle is only a handful in hundreds of years.

"My lord, shall I give you a shoulder press?"

Sophia finally whispered this, and her face turned red in an instant, she had been thinking about how to stay away from this new lord, and she never thought that one day she would take the initiative to approach him.

Hearing Sophia's words, Duke glanced back a little unexpectedly, this little girl saw herself before like a mouse seeing a cat, how did she change sex today?

But when I saw Sophia's little face flushed, there was a different kind of nervousness and cuteness. Duke's lewd nature suddenly concurrent, and said with a flirtatious smile: "Okay, little Sophia, I've been in pain all over my body recently, why don't you give me a full body massage." ”

Sophia, who had a great impression of Duke, immediately instinctively took a few steps back after seeing the familiar lewd smile on Duke's face.

At this time, Princess Jina rushed to the side hall quickly, and hurriedly said as she walked: "Duke, have you dealt with the epidemic matter?"

As a result, as soon as she entered the side hall, she saw Duke coveting Sophia's little white rabbit who had retreated to the side with the demeanor of a big bad wolf. This scene naturally reminded Princess Gina of Duke's previous tricks, especially in such a crisis situation as Storm Castle, Duke, a straw bag, was still in the mood to tease the maid?

So Ji Na said angrily: "Duke, don't you know that every day the epidemic is delayed, there is a risk of an outbreak?
