竟岗生产核算员演讲稿;re thinking about what to have for dinner.your brain also has its own sense of what you should weigh, no matter what you consciously believe. this is called your set point, but thats a misleading term, because its actually a range of about 10 or 15 pounds. you can use lifestyle choices to move your weight up and down within that range, but its much, much harder to stay outside of it. the hypothalamus, the part of the brain that regulates body weight, there are more than a dozen chemical signals in the brain that tell your body to gain weight, more than another dozen that tell your body to lose it, and the system works like a thermostat, responding to signals from the body by adjusting hunger, activity and metabolism, to keep your weight stable as conditions change. thats what a thermostat does, right? it keeps the temperature in your house the same as the weather changes outside. now you can try to change the temperature in your house by opening a window in the winter, but thats not going to change the setting on the thermostat, which will respond by kicking on the furnace to warm the place back up.your brain works exactly the same way, responding to weight loss by using powerful tools to push your body back to what it considers normal. if you lose a lot of weight, your brain reacts as if you were starving, and whether you started out fat or thin, your brains response is exactly the same. we would love to think that your brain could tell whether you need to lose weight or not, but it cant. if you do lose a lot of weight, you become hungry, and your muscles burn less energy. dr. rudy leibel of columbia university has found that people who have lost 10 percent of their body weight burn 250 to 400 calories less because their metabolism is suppressed. thats a lot of food. this means that a successful dieter must eat this much less forever than someone of the same weight who has always been thin.from an evolutionary perspective, your bodys resistance to weight loss makes sense. when food was scarce, our ancestors survival depended on conserving energy, and regaining the weight when food was available would have protected them against the next shortage. over the course of human history, starvation has been a much bigger problem than overeating. this may explain a very sad fact: set points can go up, but they rarely go down. now, if your mother ever mentioned that life is not fair, this is the kind of thing she was talking about. (laughter) successful dieting doesnt lower your set point. even after youve kept the weight off for as long as seven years, your brain keeps trying to make you gain it back. if that weight loss had been due to a long famine, that would be a sensible response. in our modern world of drive-thru burgers, its not working out so well for many of us. that difference between our ancestral past and our abundant present is the reason that dr. yoni freedhoff of the university of ottawa would like to take some of his patients back to a time when food was less available, and its also the reason that changing the food environment is really going to be the most effective solution to obesity.sadly, a temporary weight gain can become permanent. if you stay at a high weight for too long, probably a matter of years for most of us, your brain may decide that thats the new normal.psychologists classify eaters into two groups, those who rely on their hunger and those who try to control their eating through willpower, like most dieters. lets call them intuitive eaters and controlled eaters. the interesting thing is that intuitive eaters are less likely to be overweight, and they spend less time thinking about food. controlled eaters are more vulnerable to overeating in response to advertising, super-sizing, and the all-you-can-eat buffet. and a small indulgence, like eating one scoop of ice cream, is more likely to lead to a food binge in controlled eaters. children are especially vulnerable to this cycle of dieting and then binging.several long-term studies have shown that girls who diet in their early teenage years are three times more likely to become overweight five years later, even if they started at a normal weight, and all of these studies found that the same factors that predicted weight gain also predicted the development of eating disorders. the other factor, by the way, those of you who are parents, was being teased by family members about their weight. so dont do that. (laughter)i left almost all my graphs at home, but i couldnt resist throwing in just this one, because im a geek, and thats how i roll. (laughter) this is a study that looked at the risk of death over a 14-year period based on four healthy habits: eating enough fruits and vegetables, exercise three times a week, not smoking, and drinking in moderation. lets start by looking at the normal weight people in the study. the height of the bars is the risk of death, and those zero, one, two, three, four numbers on the horizontal axis are the number of those healthy habits that a given person had. and as youd expect, the healthier the lifestyle, the less likely people were to die during the study. now lets look at what happens in overweight people.the ones that had no healthy habits had a higher risk of death. adding just one healthy habit pulls overweight people back into the normal range. for obese people with no healthy habits, the risk is very high, seven times higher than the healthiest groups in the study. but a healthy lifestyle helps obese people too. in fact, if you look only at the group with all four healthy habits, you can see that weight makes very little difference. you can take control of your health by taking control of your lifestyle, even if you cant lose weight and keep it off.diets dont have very much reliability. five years after a diet, most people have regained the weight. forty percent of them have gained even more. if you think about this, the typical outcome of dieting is that youre more likely to gain weight in the long run than to lose it.if ive convinced you that dieting might be a problem, the next question is, what do you do about it? and my answer, in a word, is mindfulness. im not saying you need to learn to meditate or take up yoga. im talking about mindful eating: learning to understand your bodys signals so that you eat when youre hungry and stop when youre full, because a lot of weight gain boils down to eating when youre not hungry. how do you do it? give yourself permission to eat as much as you want, and then work on figuring out what makes your body feel good. sit down to regular meals without distractions. think about how your body feels when you start to eat and when you stop, and let your hunger decide when you should be done. it took about a year for me to learn this, but its really been worth it. i am so much more relaxed around food than i have ever been in my life. i often dont think about it. i forget we have chocolate in the house. its like aliens have taken over my brain. its just completely different. i should say that this approach to eating probably wont make you lose weight unless you often eat when youre not hungry, but doctors dont know of any approach that makes significant weight loss in a lot of people, and that is why a lot of people are now focusing on preventing weight gain instead of promoting weight loss. lets face it: if diets worked, wed all be thin already. (laughter)why do we keep doing the same thing and expecting different results? diets may seem harmless, but they actually do a lot of collateral damage. at worst, they ruin lives: weight obsession leads to eating disorders, especially in young kids. in the u.s., we have 80 percent of 10-year-old girls say theyve been on a diet. our daughters have learned to measure their worth by the wrong scale. even at its best, dieting is a waste of time and energy. it takes willpower which you could be using to help your kids with their homework or to finish that important work project, and because willpower is limited, any strategy that relies on its consistent application is pretty much guaranteed to eventually fail you when your attention moves on to something else.let me leave you with one last thought. what if we told all those dieting girls that its okay to eat when theyre hungry? what if we taught them to work with their appetite instead of fearing it? i think most of them would be happier and healthier, and as adults, many of them would probably be thinner. i wish someone had told me that back when i was 13.thanks.(applause)i have the answer to a question that weve all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now its everywhere in the culture - the x prize, the x-files, project x, tedx. whered that come from?about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. thats one of the reasons so much of what weve come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.this includes the little system in arabic called al-jebra. and al-jebr roughly translates to the system for reconciling disparate parts. al-jebr finally came into english as algebra. one example among many.the arabic texts containing this mathematical wisdom finally made their way to europe - which is to say spain - in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.but there were problems. one problem is there are some sounds in arabic that just dont make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.heres one of the culprits. this is the letter sheen, and it makes the sound we think of as sh - sh. its also the very first letter of the word shalan, which means something just like the the english word something - some undefined, unknown thing.now in arabic, we can make this definite by adding the definite article al. so this is al-shalan - the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan cant be rendered into spanish because spanish doesnt have that sh, that sh sound. so by convention, they created a rule in which they borrowed the ck sound, ck sound, from the classical greek in the form of the letter kai.later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin x. and once that happened, once this material was in latin, it formed the basis for mathematics textbooks for almost 600 years.but now we have the answer to our question. why is it that x is the unknown? x is the unknown because you cant say sh in spanish. (laughter) and i thought that was worth sharing.(applause)尊敬的各位老师，同学们，大家好！我是法学院大四学生李明，我演讲的题目是我为什么要学法律很多人听到这个题目，一定以为我太把这次演讲比赛当做儿戏了。一个简单的专业选择的问题，与我们今天的主题“中国梦”能有多大的关联呢？其实在初入燕园之时，我也只曾在大众媒体和长辈的口耳相传中听得法律职业者的种种评价，也只曾知道“宪法是我国根本大法”之类的政治课本知识，也只曾在路过国徽高悬的庄严肃穆的法院门口时好奇的回望。而今，我即将从北大法学院毕业，成为一名光荣的北大法律人，我所应当肩负的责任是什么，我可能实现的人生价值在历史的坐标下又是什么？我想，这个简单的问题，不仅仅是我四年燕园求学中努力求索的精神真谛，而且将是指导我未来发展的永恒旗帜。法律人，应该有着怎样的中国梦，这需要我们用整个人生去回答。法律人的中国梦，是维护公民合法利益的权利之梦。法治，绝不应当仅仅是宏大的制度构建，而也应当构筑起公民权利的堡垒，让苦干多年农民工兄弟早日拿到血汗钱，让征地拆迁中的血案不再上演，让猖獗一时的刑讯逼供无处藏身。法学家耶林告诉我们，要“为权利而斗争”，因为当每个人都在强权面前退却的时候，整个共同体的利益将不得不被放弃。法律人站在公民权利与强权暴力交锋的战场，捍卫每个人的权利，捍卫每个人的中国梦。法律人的中国梦，是追求社会公平的正义之梦。坚韧的法律人，让苍南县政府做到了被告席上，与浙江普通农民包郑照对簿公堂。执着的法律人，让佘祥林、赵作海获得了他们应得的国家赔偿，使冤案昭雪，真相大白。让比太阳还要光辉的公平正义洒满人间，是法律人永恒的信条。法律人的中国梦，是让中华民族真正实现民主与文明的复兴之梦。法律人梦想着让每个人都有行使民主权利的机会，共享国家发展带来的成果；法律人希望能够用制度构建约束权力的牢笼，让腐木与蛀虫无处藏身；法律人希望能够走出一条具有中国特色的民主、法治之路，让中华民族以更加文明的姿态屹立于世界东方，让中国梦成为世界所景仰的精神价值。也许还有人仅仅是为了在诉讼和争议中获得利益，利用法律规避责任而无视事实真相的存在；也许还有人仅仅是为了粉饰太平，偏袒强者欺压弱者，息事宁人而将公平正义束之高阁；也许还有人仅仅是为了维护旧秩序的稳定，坐拥恶法，助纣为虐。但中国梦的号角已经吹响，驶向中华民族伟大复兴的巨轮已经起航，一切的不完美，都等待着我们去改变。我们怎样，中国便怎样。我们是什么，中国便是什么。我们有光明，中国便不再黑暗。在古希腊神话中，代表正义的女神是这样的形象：她双眼紧蒙，代表不受干扰和高贵的逻辑理性；她手握天平，代表绝对公平绝不偏袒；她手握利剑，代表践行正义绝不姑息。法律人，正是怀着崇高的理性精神，践行对社会公平正义的追求，在推进人类文明的道路上披荆斩棘，为公民权利而战，为公平正义而战，为社会进步和民族复兴而战！我为什么要学法律，我想，法律人的中国梦，已经告诉我答案。马岩松励志演讲稿：我们为什么要谈未来 20XX为什么演讲稿（4）我叫马岩松，我是个建筑师，我今天讲的是，我们为什么要谈未来，我曾经被一个很重要的批评家问过一个问题，他说，未来将会是什么，当时我就想怎么回答这个问题。最后我给他一个答案呢，就是未来就是过去。大概是XX年吧，这时候我已经在北京工作，我们做了一个竞赛，这个竞赛在中国的一个大城市，竞赛要求建一个四百米的一个楼，然后政府的人说，虽然我们写的是400米，但是呢，你们可以来表达你们认为的一个高度，他这个话呢大家都明白了，就是他想要一个更高的，他要一个更高的楼，来表达这个城市的一个信心。结果呢，所有的建筑师都
