Jiang Fuyue continued her high-frequency flipping through the exam papers.
Meanwhile, Chiba Tosaki was completely the opposite. He started from the theoretical part, then moved to the experimental section, reviewing each step from the first question to the last twice over.
As Matsuda, the leader of R country, had said, there was no flaw to be found anywhere.
He didn’t believe it.
He began a third round.
The more he looked, the heavier his heart sank, but he maintained his composure on the surface.
Thankfully, there was no movement from Jiang Fuyue’s side either.
He was confident that she wouldn’t find any faults with him.
If it came down to “necessary steps” in the end, he might not lose to Jiang Fuyue because he streamlined his process.
All he had to do now was wait for the final ten minutes to pass…
But just then —
“I’ve found something.”
Chiba Tosaki’s eyelids twitched.
The presiding chairman gestured for the staff to bring a microphone to Jiang Fuyue.
Yan Zhenfeng and Qin Libin exchanged a glance. Had she really found a mistake?
But the grading committee was not easy to deal with. Why hadn’t they noticed it earlier?
Other country leaders shared the same doubts, looking at Jiang Fuyue with increasing focus and… anticipation.
Everyone sitting here today was a physicist with professional knowledge.
What was more thrilling than a clash of minds?
After all, their minds and visions were not limited to their own countries but to the broader world of physics.
Because —
Knowledge knows no borders, and genius should be respected!
The presiding chairman: “Jiang Fuyue, please explain.”
“In the first question of the experimental section, in the third sub-question, steps six and seven, Chiba Tosaki used the abbreviation ‘ppm.’ According to the IPhO exam regulations, the text of the test must use SI units. However, ‘ppm’ is not an SI unit.”
“SI units, International System of Units, also known as the metric system, is the most widely used standard measurement system in the world.”
“The International System of Units is constructed according to the consistent measurement unit principle, which means that only SI prefixes can be used to construct multiple and fractional units.”
“According to the above rules, units such as liters, tons, and lumens are not included in the International System of Units.”
Jiang Fuyue: “Of course, Chiba Tosaki did not use these, but instead used SI derived units.”
“SI derived units include units with special names assigned by the International Committee for Weights and Measures, such as newtons, watts, volts, and lumens, as well as those without special names. Units like meters per second, joules per kelvin, and radians per second.”
“For dimensionless quantities in SI units, these are ratios of two identical SI units. For example: refractive index, coefficient of dynamic friction, linear strain, relative atomic mass, proton number, power magnitude, and plane angle.”
“In this question, the refractive index expressed by Chiba Tosaki uses SI units as the ratio of two velocities in SI units, namely m·s/(m·s)=1. The use of multiples and fractional units should not use SI prefixes, but instead use powers of 10, mathematical symbols such as %, or similar units such as micrograms per gram (μg/g) and milliliters per cubic meter (mL/m), but not the abbreviation ‘ppm.'”
“So —” Jiang Fuyue swept her gaze over everyone present, finally locking eyes with the doll-like face opposite her, enunciating each word clearly, “Chiba Tosaki did not answer according to the exam rules. Points should be deducted here!”
