The great physicist Bohr once said, "My greatest merit is that I am not afraid to expose my stupidity in front of my students." Daring to be wrong is a kind of courage, but also a kind of wisdom. People are a piece of unshaped jade, in the long journey to gradually grind into a rare jade, and dare to make mistakes is the quality of that dexterous carving knife, little by little, carved out those beautiful form, life will become colorful.
Dare to be wrong is a courage to recognize the self of the courage. The first thing you need to do is to make sure that you have a good understanding of what you are doing and how you are doing it. Life can avoid having mistakes, but to experience the wrong life is not necessarily wrong. All people have mistakes, the key is whether you dare to admit. Soghridi said, "Life without scrutiny is worthless." A life that is afraid to even face their mistakes is sad and ridiculous; they lose to themselves. If you refuse to see that mistakes exist, then you will only sink deeper and deeper into the mire of mistakes. Don't let the mistakes of life brew a wrong life.
Dare to be wrong is a positive attitude to life. Dare to try to have results, perhaps the process is full of pain and suffering, perhaps the final result is unsatisfactory. But as long as the heart has done, what is all this? Once fell down, once struggled to stand up, once frustration and error, the achievement of our strong heart and beautiful life accumulation. Mistakes can at least let us know a wrong way, these are the years and those fearless heart of the gift, life lessons and experience is not to get from the comfort of ease? To err is a give and take, only a gain. And life is full because of it.
Dare to make a mistake is a kind of wisdom of great enlightenment, make a mistake so that people are wise, make a mistake so that people wake up. The real wise people are those who are good at learning from mistakes, they know that the pretense of perfection will only ever stagnate. Einstein has a famous "big circle, small circle" theory: the average person knows is a small circle, and he knows is a big circle. Although he knew more, but outside the circle of contact with the unknown world is also more, so he did not know more than ordinary people. What a deep wisdom this is, a profound sense of life issued after recognizing the infinity of the universe and the insignificance of human beings. If we truly understand this true meaning of life, then we do not have to be woefully embarrassed by it when we are wrong, who can easily judge what is wrong and what is right? If you still have the courage to show your mistakes, at least it may prove that you still have wisdom.
You can not have a brilliant mind, you can not exceed the normal talent, but you must have the courage to make mistakes, because mistakes are also a kind of spirit! The first time I saw this, it was a very good idea to get it right! I'm not sure if I'm going to be able to do that! I'm sorry, but I don't know what to say.)
There is a kingdom of stamps hidden in my little stamp album. These stamps are of different sizes and colors. My favorite, to count the "ancient towns in the water towns" group of stamps.
This group of "Ancient Towns in Water Towns" stamps was issued on April 7, 2001, printed by the Beijing Stamp Factory, the whole set of **** there are six, contains six ancient towns in the Jiangnan water towns, Wu Xian Jiaozhi, Kunshan Zhouzhuang, Wujiang Tongli, Tongxiang Wuzhen, Huzhou Nanxun, Jiashan Xitang. This stamp is a painter called Huang Li painted, black and white color, the intensity of the appropriate, written in the middle of the stamp "water township" two calligraphy words, but the use of bright red, so that this set of stamps appear both rustic and elegant and full of oriental charm. Its face value is different, adding up to only 68 yuan, the circulation *** is 17 million sets, the specification is 30mm × 40mm, each stamp is printed below a small "T", on behalf of this set of stamps is to be kind of stamps.
Whenever I open the philatelic book, I will turn to the "water towns" this side of this group of stamps apricot blossom spring rain, green hills and water, the river is longitudinal, stone bridges such as the moon, green brick tile, boats such as shuttles, the Jiangnan water towns is how beautiful ah! Show us a picture of the ancient appearance of the landscape still exists. Zhejiang Jiashan Xitang town, the morning dew, the narrow waterway is clear, blue waves, reflecting a building contains a strong ancient flavor, and a tree through the vicissitudes of life.

Getting the nutrients we Also, trying to balance the calories we consume from food with the calories we burn through physical activities is the foundation for healthy eating. Also, trying to balance the calories we consume from food with the calories we burn through physical activities is the foundation for healthy lifestyle.
Senior Chemistry, UrgentNH3 has a molecular weight of 17 and a molar mass of 17 grams per mole
5.1 grams is 5.1/17 = 0.3 mol
CO2's molecular weight 44, molar mass 44 g/mol
17.6 g is 17.6/44=0.4 mol
1 mol=NA particles ≈ 6.02x10^23 particles
This gives a molecule number ratio of 0.3NA:0.4NA=3:4
Under the same conditions, at the same temperature and pressure, the volume ratio is equal to the matter ratio
Volume ratio is 3:4
1 NH3-1+3=4 atoms-7+1x3=10 protons-10 electrons
1 CO2-1+2=3 atoms -6+8x2=22 protons-22 electrons
This gives a ratio of 0.3x4:0.4x3=1
Proton, electron ratio = 0.3x10:0.4x22=3:8.8
For example, if all of them contain 22 electrons, nNH3=22/10= 2.2mol
nCO2=1mol, mass ratio 2.2x17:44x1=37.4:44
High school chemistry rush!
(NH4)2CO3 + 2NaOH == heating == 2NH3(gas) + Na2CO3 + 2H2O
NH4HCO3 + 2NaOH == heating == NH3(gas) + Na2CO3 + 2H2O
(NH4)2S + 2NaOH == heating == 2NH3(gas) + Na2S + 2H2O
NH4HS + 2NaOH == Heating == NH3(gas) + Na2S + 2H2O
So it is 2:2:2:2 i.e. 1:1:1:1

Math Junior's Urgent 。。。。That square one says, triangle three sides for ABC,then the three squares area are A square, B square, C square, S1 + S2 = S3, that is the sum of the two small area of the square for the large area of the square, and in the right triangle, the square of the hypotenuse will be equal to the sum of the two sides squared, so it holds. A similar proof can be done for the remaining two. Hopefully adopted *^_^*
Urgent Q6600 To upgrade?The performance of these two processors is more than enough for you to play 2d games, the performance of Q6600 used to be intel's high-level products, the performance is certainly in the 440 above, overclocking, then, stability is very important, so the power supply of your motherboard, power supply, heat dissipation, etc. There are certain requirements, the Q6600 is a relatively old model of the processor, although the 2 cache is higher, more can be super, but after all, it is the old process, the heat is very high, but it is the old process. The Q6600 is an older processor, the heat is greater than the new processor, small super to 3G after the performance is still close to the preset Q9400. if if the business package to open the 4-core, and you have experience in overclocking, the price of 6600 is too much higher than the 440, I recommend that you buy the AMD440, but open the core is still a little risky. If you don't want that much trouble, the cheaper Q6600 is still worth buying.
