Chapter 295: She Makes No Mistakes, Crush the Enemy in Public (Part 3)
Jiang Fuyue continued to flip through the test paper at a high frequency.
Chiba Hamasaki did the complete opposite. He started from the theoretical part and then went to the experimental part, and read each step twice in order from the first question to the last question.
Just as Mr. Matsuda (the leader of the R country team) said, there was no flaw at all.
He doesn't believe it.
Start the third time.
The more I looked, the gloomier my heart became, but I remained expressionless.
Fortunately, there was no movement from Jiang Fuyue.
He was very confident that the other party would not be able to catch him.
If we really have to look at the "necessary steps" in the end, his simplification may not be inferior to Jiang Fuyue's.
Now we just have to wait for the last ten minutes to pass...
But at this moment——
"I've discovered something."
Hamasaki Chiba's eyelids twitched.
The executive chairman signaled the staff to hand the microphone to Jiang Fuyue.
Yan Zhenfeng and Qin Libin looked at each other. Is there really something wrong?
But the grading team is not a pushover, why didn’t they notice it at the time?
Team leaders from other countries also had the same doubts, and their eyes looking at Jiang Fuyue became more focused and... full of expectations.
Everyone who can sit here today is a physicist with professional knowledge.
What could excite them more than the collision of ideas?
After all, their minds and vision are far more than limited to their own country, but look to the broader field of world physics.
They cherish and love talents. No matter whether the student is from China or Country R, they treat them equally without any favoritism or selfishness, and without any nationalism.
because--
Knowledge has no borders, and geniuses should be respected!
Executive Chairman: "Jiang Fuyue, please elaborate."
"In the experimental section, question 1, sub-question 3, steps 6 and 7, Hamasaki Chiba used the abbreviation ppm. According to the IPhO syllabus, the text must use SI units. However, ppm is not an SI unit."
SI units, International System of Units, also known as the International System of Units, formerly known as the "International Metric System", is the most commonly used standard measurement unit system in the world [1].
The International System of Units is constructed according to the principle of a consistent system of units, that is, multiples and fractions of units can only be formed using SI prefixes.
According to the above rules, units such as liters for volume, tons for weight, and nits for brightness do not belong to the International System of Units [1].
Jiang Fuyue: "Of course, Hamasaki Chiba didn't use these. He used SI derived units."
"SI derived units include those that have been given specific names by the General Conference on Weights and Measures, such as the newton, watt, volt, and lumen, as well as those that have not been given specific names, such as the meter per second, joule per kelvin, and radian per second."
"The SI units for dimensionless quantities are the ratio of two identical SI units. Examples include refractive index, coefficient of kinetic friction, linear strain, relative atomic mass, proton number, power magnitude, and plane angle. [1]"
In this question, Hamasaki Chiba expressed the refractive index using the SI unit of the ratio of two SI units of velocity, i.e., m·s/(m·s) = 1. Multiples and fractions are not constructed using SI prefixes, so powers of 10 should be used. Of course, the mathematical symbol % can be used instead of 10, or similar units such as micrograms per gram (μg/g) or milliliters per cubic meter (mL/m) can be used instead of 10, but the abbreviation ppm should not be used.
"So—" Jiang Fuyue slowly scanned the crowd, finally landing his gaze on the baby-faced figure across from him. He spoke each word with emphasis, "Hamazaki Chiba didn't answer the questions according to the exam rules, so points should be deducted!"
Three updates, one thousand words, really brain-burning writing.
