I Can Meet with Dead Scientists

Looking at Xiaoli, who keeps talking about science incessantly.

Old Li eventually had to give up the idea of arranging a match for his daughter.

Actually, this is quite normal.

After all, in a normal course of events, the union of Xiaoli and Zhao Mingcheng had its reasons.

They were certainly in love, but there was also a certain level of interest exchange on the family level:

Zhao Mingcheng's father, Zhao Tingzhi, was a member of the Yuanfeng Faction, staunchly supporting reform or the New Laws faction, which opposed Li Gefei for a long time.

However, at this time, Emperor Huizong had just ascended the throne, and the two opposing factions were relatively restrained, with many choosing to marry to ease relations.

The union of Xiaoli and Zhao Mingcheng was influenced by certain factors, otherwise, Old Li wouldn't have agreed so quickly.

Of course.

In later generations, when discussing the marriage of Xiaoli and Zhao Mingcheng, people rarely mentioned the exchange of interests.

After all, for literary youth, love should be pure and untainted.

But in ancient Huaxia.

How many men and women born into official families could truly pursue untainted love?

For example, many in later generations knew that Xiaoli and Zhao Mingcheng were exceptionally loving, a model couple, an immortal match.

But few knew they lived apart shortly after marriage:

In just over a year, Emperor Huizong would employ Cai Jing, purging Sima Guang's old faction whom he loathed.

At that time, being a protégé of the old faction's prominent Su Shi, Li Gefei naturally was assigned to this faction, lost his job, and was sent back to his hometown.

Meanwhile, relying on his Yuanfeng faction background, Zhao Mingcheng's father, Zhao Tingzhi, was promoted three levels, becoming exceedingly prominent.

At the time, Xiaoli even sought Zhao Tingzhi's help, asking her father-in-law to exonerate her father.

Who knew.

What she awaited was not her father's pardon but Zhao family's declaration of boundaries:

Utilizing the court's new policy that "members of the Imperial Family must not marry into the Yuanyou Faction," even though not part of the Imperial Family, Zhao family expelled Xiaoli from the Capital City.

Xiaoli's phrase "burning hands can warm the heart" was written against this backdrop.

A few more years later.

Cai Jing was dismissed, Yuanyou Faction members were restored, allowing Xiaoli to reunite with Zhao Mingcheng in the Capital City.

However, the world is unpredictable. The following year, Cai Jing returned to office, and Zhao Tingzhi, who had been contending against Cai Jing for power, suddenly passed away.

And so.

Cai Jing acted, and the entire Zhao family was thrown into prison.

Among them, Zhao Mingcheng spent a few months in jail but was released due to lack of charges, though he lost his job and home.

Thus, he could only follow Xiaoli to seclude in Qing Prefecture, which was the most loving ten years of their marriage.

Later on, Zhao Mingcheng's revival, and as soon as he was away from Li Qingzhao's gaze, as they were seeing less and less of each other, Zhao Mingcheng soon took several concubines—some later defended this as a norm in ancient times, but would you read Li Qingzhao's "Feelings·Preface"?

A few more years later.

Zhao Mingcheng made the scandalous move of abandoning his city and fleeing while serving as a prefect, prompting Xiaoli to write her most resolute line: "Even now, I think of Xiang Yu, preferring not to cross the Jiangdong."

Since then, Xiaoli and Zhao Mingcheng's affection plummeted to an all-time low, ultimately leading to Zhao Mingcheng's death due to depression.

It can be said this way:

Their love began with affection and ended with contempt.

Can one say that such a Xiaoli...

Was truly happy?

Clearly, in those ten years at Qing Prefecture, yes, no one can deny that.

But what about those six years expelled from the Capital City, and the years post-separation?

The entire marriage?

Xiaoli's subsequent poems are enough to tell the whole story.

In later generations, Xu Yun loved a phrase: nightmares are better than dreams.

Because nightmares, after all, are dreams.

No matter how desperate the scenarios you encounter in your dream, once you wake up, at least nothing gets worse.

But beautiful dreams are different.

Once shattered, the gap can crush a person entirely.

Though middle-aged Xiaoli wasn't crushed by the shattered dream's shock.

However, from her words, it is not hard to see that her state of mind underwent quite some pessimistic changes.

Therefore, maybe in this timeline, Xiaoli not meeting Zhao Mingcheng could be a blessing.....

Of course.

At this moment, Xu Yun was unaware of these occurrences at the Li Mansion.

After leaving the mysterious man's house, he went straight back to Old Su Mansion to start preparing his lesson plan.

The next day.

Xiaoli arrived on time, whereas Xiaozhao, as Old Su had predicted, was nowhere to be seen.

At the same time, Xu Yun also noticed.

Something seemed off about Xiaoli's mood, underneath the excitement was a hint of melancholy.

However, Xu Yun didn't choose to probe further, for as long as she was attending class, it meant the young lady was okay.

"Today we are discussing acceleration, a physical quantity that describes how fast a velocity changes..."

The basic concept of acceleration isn't too hard; simply put, it is a vector generated by force.

In later textbooks, it's primarily explained through the motion state of an object, then extended to uniform circular motion and such.

But to actually understand acceleration, starting from its units might be even easier, a small technique of Xu Yun:

The unit of acceleration is m/s², speed is m/s, and time is s.

A change in speed over a period divided by that time shows m/s/s=m/s², representing acceleration's unit.

After more than an hour.

Seeing Xiaoli's bewildered face, Xu Yun smiled slightly:

"Miss Li, isn't it very simple?"

Xiaoli stared with eyes like spirals:
