Chapter 23 A Sudden Inspiration
For the next two days, Li Ang remained in Maple Leaf Town.
Complete the experiments on the tricks mentioned in the book "0-Ring Universal Magic and Basic Potions".
However, from an economic perspective, Li Ang spends more time experimenting with and optimizing spells that do not require casting materials.
Li Ang plans to experiment with and optimize spells like [Fire Spell] and [Freezing Ray], which require money, when he has more time and resources.
On the morning of the third day, Li Ang memorized the contents of "0-Ring Universal Magic and Basic Potions," hid it in a secluded place, and then, taking the short sword he had seized from the witch hunter team, activated [Interdimensional Travel] to return to America.
The familiar apartment room, the familiar wide and soft bed.
Li Ang returned to 1960.
At the same time, a message flashed on the system panel: [Countdown: 18:12:24].
Li Ang glanced at the short sword in his hand and the Earth Flame Stone powder in the pouch at his waist, enough to unleash two [Burning Fire] spells.
"This time, the cooldown time for the teleportation is much shorter than last time."
"In terms of item value alone, this medieval 'antique' short sword, along with the two sets of spellcasting materials, should be worth no less than the silver coins from the Kingdom of Frank."
"The cooldown time is now far less than 72 hours, meaning that even items of the same value will have their cooldown time shortened if carried around for an extended period."
"I wonder how much of a 'shortening' this is. Maybe next time I can try bringing back more stuff from Ioria."
Without being able to guarantee the survival conditions in Ioria, Li Ang did not plan to bring firearms or similar items there.
The risk and return are not proportional.
After a brief recap of what he gained from this trip to Ioria, Li Ang, despite having a day off today, still doesn't intend to waste any time.
Study math at home first, then go to the gym in the evening to try and complete the physique quest. If you still have time, go to Martin's General Store and ask Martin to help you collect medieval "antique" short swords.
As for the upcoming wizard apprentice gathering in Ioria, considering the time flow conversion between the two realms, Li Ang has no need to rush.
……
Li Ang sat at his desk, flipping through his math book.
[Your hard work has earned you +1 math experience]
[Your hard work has earned you +1 math experience]
It's quite amazing, actually. In Ioria, Leon activated [Mental Focus], which temporarily boosted his mental strength, allowing him to assist in spellcasting or intimidate other wizard apprentices.
At this time in America 60 years ago, he still possessed "mental focus" and was able to study mathematics without distraction.
There wasn't the slightest sense of unease in my heart.
This feeling of traveling between two worlds and studying magic and science respectively fascinated Li Ang.
As his mathematical experience points gradually increased, even though he hadn't yet reached level 2 in mathematics, Li Ang felt that his understanding of mathematics was constantly deepening.
He is particularly keenly interested in the algebra-related material he is currently studying.
In fact, Li Ang had considered bringing the well-known mathematical theorems of later generations to 1960 to help him make a name for himself.
For example, the famous Seven Conjectures proposed by the Clay Institute in 2000.
In 1960, the very act of conjecturing was a game-changer.
Not to mention the Poincaré conjecture, which has already been proven.
The key issue is that although Li Ang was quite good at mathematics in his previous life, and usually got full marks in tests, he had never actually encountered anything related to mathematical conjectures.
A perfect score on the Mathematical Analysis and Advanced Algebra exams is still far from being a true mathematical genius.
But now everything is different.
After activating [Mental Focus] and continuously improving his mathematical experience, Li Ang looked at the operator symbols on the book in front of him and felt a feeling he had never experienced before.
This area looks familiar.
"Oh right, it's the last question I helped Nicole with yesterday."
"Gaussian elimination based on block matrix structures might be able to construct a new framework that combines Weisstein factorization and Schur complement theory."
In linear algebra and matrix theory, the Schul complement of a submatrix of a matrix is a matrix of the same size as the other submatrixes…
"In the process of Gaussian elimination, we then introduce recursive decomposition using Schul complement..."
Li Ang's eyes darted quickly across the math book. He didn't know how much time had passed, but he felt a headache coming on and couldn't help rubbing his temples.
He seems to have discovered something novel in linear algebra.
However, this is currently just an idea, and due to his current level of mathematical ability, he is not yet able to fully develop it.
Li Ang understood that such inspiration was fleeting, and if he missed this opportunity, he didn't know when he would encounter it again.
He quickly took notes with pen and paper.
"Hmm... First, we should prove the equivalence theorem between block Gaussian elimination and Weinstein factorization..."
'Perhaps we can optimize in the direction of M-matrix or H-matrix.'
Li Ang pondered how to proceed, or whether to produce a paper based on his research findings.
Li Ang had given serious thought to the idea of publishing a paper in the United States.
He has an academic superstar system, so publishing papers is something he can't avoid in essence.
However, Li Ang thought that it would be enough to publish papers in the early stages to help improve his reputation. Once he "rose up" in Ioria, there would be no need for him to continue publishing papers in America.
It's a bit of a waste of time.
Even the best scientist can't compare to a wizard.
Of course, this is just Li Ang's long-term vision. Right now, if he wants to publish a paper, others might not accept it.
"Wait, wouldn't it be better to use Schur complement recursive decomposition to preprocess the matrix structure here...?"
A sudden inspiration struck Li Ang, and he picked up paper and pen to continue his calculations.
When studying mathematical problems, a solid foundation is important, but a sudden flash of inspiration is even more crucial.
Sometimes, with the right inspiration, a problem that has troubled mathematicians for decades or even centuries can be solved in an instant.
Li Ang felt enveloped in inspiration, and with the added boost of the skill [Mental Focus], he quickly wrote down one arithmetic symbol after another on the draft paper.
At the beginning, Li Ang wrote very quickly, faster than he had in the past few days when he was studying mathematics.
As expected, an hour later, he got stuck.
"It's already quite impressive that you were able to record this much."
"Once I find inspiration again, or accumulate more mathematical experience and improve my math skills, I might just figure it out directly."
"By the time we finish the paper, publishing it in a journal will cost money, right? We'll need to figure out how much to charge later."
"Now... go to the gym to trigger a mission!"
Li Ang stretched and looked at the draft paper on the table covered with calculations, feeling quite pleased with himself.
Now that he had come to America in the 60s, Li Ang should adapt to local customs and not flaunt his gray wizard robes all day long.
Wearing a clean tracksuit, he picked up his backpack, hesitated for a couple of seconds, then opened it and put the medieval "antique" short sword inside.
If I have time after my workout, I'll let Martin take a look.
