After Rebirth, I Am the White Moonlight of All The Big Brothers

Jiang Fuyue still kept a high frequency of flipping through the exam papers.

On the other hand, Chiba Hamasaki is completely the opposite. From the theoretical part to the experimental part, in the order of the first question to the last question, each step is read twice.

Sure enough, as Matsuda-kun (the leader of the R country) said, there is no flaw.

He doesn't believe it.

Start a third time.

The more I look, the more my heart sinks, but there is no expression on my face.

Fortunately, there was no movement on Jiang Fuyue's side.

He is very confident that he will not be caught by the other party.

If he really depends on the "necessary steps" in the end, his streamlining will not necessarily lose to Jiang Fuyue.

Now just waiting for the last ten minutes to pass...

But at this moment-

"I have found it."

Chiba Hamasaki's eyelids jumped.

The executive chairman motioned to the staff to send a microphone to Jiang Fuyue.

Yan Zhenfeng and Qin Libin looked at each other, is there really something wrong?

But the revision group is not a vegetarian, why didn't they find out at the time?

The leaders of other countries also had the same doubts, their eyes looking at Jiang Fuyue became more focused, and... full of expectations.

Anyone who can sit here today is a physicist with expertise.

What could make them more excited than the collision of ideas?

In the final analysis, their minds and visions are not limited to their own countries, but to the broader world of physics.

Cherish talents, love talents, no matter whether this student is from China or R country, they all treat them equally, without any partiality and selfishness, let alone the slightest bit of nationalism.

because--

Knowledge knows no borders, and geniuses should be respected!

Executive Chairman: "Jiang Fuyue, please elaborate."

"In the third question of the first question in the experimental part, and in the sixth and seventh steps, Hamasaki Chiba used the abbreviation ppm. According to the IPhO syllabus, the text of the test question must use SI units. But ppm is not an SI unit."

SI unit, International System of Units, also known as the International System of Units, formerly known as the "Universal Metric System", is the most commonly used standard system of measurement and measurement in the world [1].

The International System of Units is formed according to the principle of the consistent measurement unit system, that is, multiples and fractional units can only be formed through the SI prefix.

According to the above rules, such as capacity unit liter, weight unit ton, brightness unit nit, etc. do not belong to the SI unit [1].

Jiang Fuyue: "Of course, Chiba Hamasaki didn't use these, he used SI derived units."

"The SI derived units include both those units that have been given special names by the International Congress of Weights and Measures, such as Newtons, Watts, Volts, Lumens, etc.; and those units that have not been given special names, such as meters per second, joules per Kelvin, radians per second ."

"Where the SI unit for dimensionless quantities is the ratio of two identical SI units. For example: refractive index, kinetic friction factor, linear strain, relative atomic mass, number of protons, power magnitude, plane angle .[1]"

"In this question, the refractive index expressed by Chiba Hamasaki, its SI unit is the ratio of the SI units of the two speeds, that is, m s/(m s) = 1. Its multiples and fractional units are not used in The SI prefix is ​​formed, so it should be a power of 10. Of course, the mathematical symbol % can be used instead of 10, or 10 can be replaced by similar units such as micrograms per gram (μg/g) and milliliters per cubic meter (mL/m), but The ppm abbreviation should not be used."

"So—" Jiang Fuyue slowly swept over the people present, and finally her eyes fell on the baby's face on the opposite side, and she paused, "Hamasaki Chiba did not answer according to the exam rules, and points should be deducted here!"

Three shifts, a thousand words, writing is really brain-burning.
