It's really not easy, there are still instruments I know in the laboratory! I just looked at so many laboratories, which are full of incomparably tall intelligent equipment, and now a balance suddenly appeared, Shen Yibin felt very kind, so he turned his head and asked the staff here, "Excuse me, can this let me play for a while?" ”

"We don't really use this much, you can play as much as you want." The experimenter pursed his lips and smiled, in fact, the instruments in this are all bought by Shen Yibin with money, who can stop him if he wants to play? Besides, this balance doesn't have a lot of money, so even if it breaks it, it's not a big deal.

"Good! Come, Ha'er, Erdan, sit down, I'll teach you how to play this! Shen Yibin vaguely remembered the operation of some balances, reset the game code to zero, adjusted the balance left and right, then looked at the things on the experimental table, found a piece of eraser and put it in the tray on the right side of the balance, and then picked up the tweezers and prepared to clamp the weights and put them in the tray on the left for weighing.

"Mr. Shen, the ...... If you put the weight and the weighing object in the opposite direction, generally speaking, the tray on the left should be placed on the object to be weighed, and the weight should be placed on the right, so that it is easier to add weights. Seeing this, the experimenter couldn't help but remind that if his experimental dog made such a low-level mistake, he would definitely be kicked out of the laboratory immediately!

"Hehe, it's been a long time since I graduated, and I forgot about it!" Shen Yibin's old face turned red, this is a big mess! Fortunately, there were not many people in this laboratory, and Shen Yibin's skin was still relatively thick, so he insisted on it and quickly changed the position of the weight and the object.

"Well, place the object and the weight at each end of the scale, and wait until the balance is back level, and you can measure the weight of the object! Look, simple, right? After the experimenter's correction, Shen Yibin finally remembered the correct operation method and quickly measured the weight of this eraser.

"Hmm~" Ha'er yawned, as if he thought this thing was so boring, it was better to go to Bear Mountain to play with his relatives, but the second egg watched it with relish, and stretched out his paws to touch the weight.

Generally speaking, moving weights need to use tweezers, so as not to corrode the weight with sweat on the hand and cause the accuracy to decrease, but since the second egg is happy, let it play, it's a big deal to let the laboratory sell another set of weights, and these weights seem to be very good at the anti-corrosion process, and there should be no problem to catch it once or twice.

"This is one hundred grams, this is fifty grams, this is ten grams, this is five grams......" Every time Erdan picked up a weight, Shen Yibin glanced at the number on the weight and reported its weight, and after a while, Erdan played with the whole set of weights, and then looked left and right, trying to find a suitable object to weigh.

"Well, why don't you try this?" Shen Yibin handed over his mobile phone, well, Shen Yibin still remembers the weight of this mobile phone, if I am not mistaken, it should be one hundred and forty-five grams, use the balance to weigh, just need to put a hundred grams of weights on the right tray, two twenty grams of weights and a five grams of weights, or use a hundred grams and a fifty grams, and then adjust the code for weighing.

"Tsk~Tsk~" Without waiting for Shen Yibin to put the phone in the balance tray, Erdan took it first and tossed it on his paws, as if he was weighing it, not to mention, this little guy's posture is also decent.

"Oh, you can try it!" Yo he, I see how many times you can measure the correct weight, Shen Yibin smiled and handed over the weight.

Erdan gently put the mobile phone on the tray on the left, and then picked up a hundred-gram weight and put it on the tray on the left without hesitation, and then stretched his paw to the twenty-gram weight, which made Shen Yibin slightly surprised, I go, how did it find it so accurately? If you let me try, I might be able to get a fifty-gram weight the second time!

What surprised Shen Yibin even more was still behind, Erdan didn't seem to have thought about it at all, and directly picked up a twenty-gram weight and a five-gram weight and put it on the scale, and then looked at Shen Yibin and screamed twice, as if he was showing off, look, am I measuring accurately?

I'll go, you're much faster than me! Shen Yibin's eyes popped out when he saw it, there was still this kind of operation? Ma Dan, how can I say that I am also a college student, and there is no beast who can play the scales well, which is simply unreasonable!

"Come on, try this again!" Shen Yibin put the power bank on the table again, it must have been a coincidence just now! Well, it's definitely a coincidence, I won't lose to a brute! Do you have the ability to measure the weight of this?

Throwing the power bank to Erdan, Shen Yibin took back his mobile phone and opened the browser, and began to search for the weight of this power bank, and soon found accurate data on the official website, the weight of this power bank is three hundred and sixty-nine grams! Haha, this weight is not very easy for you to weigh with weights, maybe you have to use the yard.

But if you don't plan to use the game, but plan to measure all with weights, it's not impossible, but the number of weights to be used is a bit too much, and even a gram or two of weights will be used later, I don't believe that the second egg can even measure such a tiny weight!

This time, the power bank weighed on the paws for a little longer, about half a minute, and the second egg put the power bank on the balance tray, and then did not hesitate to put the 200-gram weight on the right tray, and then took another 100 grams, 50 grams and 10 grams.

"Mr. Shen, you raccoon is so smart!" At this time, the experimenters in the laboratory also stopped what they were doing and gathered around to watch Erdan's performance.

"Hey, if you're smart, it's time to adjust the game code next, then you still need to fiddle with the weights so hard!" Shen Yibin pretended to smile disdainfully, in fact, he praised the second egg to the sky in his heart, second egg, hurry up and come on! Hurry up and measure the accurate weight of the power bank.

"It's okay to talk about five grams, but I'm afraid that the weights weighing one gram and two grams are not good to weigh out by claws, right? I guess it's going to take a few weight changes before it succeeds. The experimenter who reminded Shen Yibin to put the weights and weighed things backwards said that in fact, at about this time, you can consider using the game code for accurate measurements, but everyone is very considerate, you really can't ask too much for a raccoon.

However, Erdan still surprised them, Erdan did not hesitate to take a five-gram weight and two two-gram weights and put them on the tray on the right, the balance quickly regained balance, and the experimenter quickly glanced at the number on the weight on the right tray, "Three hundred and sixty-nine grams!" ”

"This power bank is so heavy!" Shen Yibin directly showed his mobile phone and showed everyone the specifications of the power bank.

"I haven't changed the weight once, even if you let me go, I can't!" The experimenters shrugged, believing that they could not accurately measure the weight of an object by hand, but of course they could use the code to do so, and it was not necessarily slower than Erdan.

"Let's try this again, I just measured this, it's 274.4 grams!" Now the experimenters seem to have found a funny thing, an experimenter took a piece of wood from the side, it smelled faint medicinal smell, it should be some kind of experimental raw material!

"Well, this weight is good, and the requirements for accuracy are much higher than just now!" Shen Yibin nodded and praised, if you want to put the weights without changing them at one time, you must require the measurement accuracy of the second egg claw to be more than 0.1 gram, which is a bit difficult, right? It's worthy of being engaged in research, and the brain is better than mine.

"Hey, try it!" Shen Yibin handed the wooden block to Erdan's paws.

"It shouldn't work this time, right? In the past, those gold medal salesmen could weigh candy by hand, but they could measure the money at most, but they couldn't be accurate to 0.1 gram! "Money is an ancient Chinese unit of weight, about five grams per coin, this accuracy is amazing enough, but Erdan's performance just now has greatly exceeded this limit.

"Well, I also know that some herb grabbers in Chinese medicine pharmacies can catch the exact weight of medicinal materials with a single grab, but they are not much better than the salesperson you just mentioned, and they definitely can't weigh one gram by hand!" Since it is a research institute for medicine, it must be indispensable to study traditional Chinese medicine, so soon some people remembered the medicine masters in the big pharmacy, and their skills are only higher than those gold medal salesmen.

"Well, the gold medal salesmen you mentioned have gradually disappeared since the nineties, but these medicine masters are still staying in the pharmacy, but people's skills have been accumulated for decades, how old is this little guy? How did you come up with this quest? "Compared with Erdan, the age of those medicine masters is really alive to Erha.

"Shhhh As soon as he saw Erdan's paw reaching for the weight, the discussion in the laboratory came to an abrupt end, and the big guys stared at Erdan's paw with wide eyes, watching it place the weights on the tray on the right without blinking.

Two hundred grams, fifty grams, twenty grams, then two two grams, and finally the second egg stretched his paw towards the 0.5 gram weight.

Well? The weight of this piece of wood is 274.4 grams, and the weight of your weight is 274.5 grams! Is Erdan finally wrong?
