今天的科学课作业就是用意大利面和棉花糖来去做一个高塔,现在正在搭第三层, 这是我们做的最后一层了。哇,总共用了四十八块。

台风烟花来了,上海中心的煮泥器晃动起来了。我也来模拟一下,为什么煮泥器能保护大楼呢?我用意大利面和棉花糖做了一个 高塔,当高塔震动以后。哇哇哇,真的好厉害啊,阻力器都晃起来了。来,看到仔细看塔的现象啊。好,现在我把阻力器拿掉,再晃动一下。看到吧, 这高塔换的更厉害了吧。原来这阻尼器能够保护高塔。我晃动的能量或者是风吹动高塔的能量被阻尼器分掉了一部分。 然后煮泥器是高高塔的保护器。你在家是不是也可以试试做一个比我漂亮一点的意大利面棉花糖。真的是棉花糖哎,不信我吃给你看。






several years ago, here at ted, peter skillman introduced a design challenge called the marshmallow challenge and the idea is pretty simple teams of four have to build a tallest free standing structure out of twenty sticks of spaghetti, one yard of tape, one yard of string and a marshmallow the marshmallow has to be on top and though it seems really simple, it's actually pretty hard, because it forces people to collaborate very quickly and so i thought this was an interesting idea and i incorporated it into a design workshop and it was a huge success and since then i've conducted about seventy design workshops across the world with students and designer is in architects even the ctos of the fortune fifty and there's something about this exercise that reveals very deep lessons about the nature of collaboration and i'd like to share some of them with you so normally most people begin by orienting themselves to the task they talk about it they figure out what it's going to look like they jockey for power then they spend some time planning organizing they sketching they lay out spaghetti, they'd spend the majority of their time assembling the sticks into ever growing structures and then finally just as they're running out of time someone takes out the marshmallow and then they gingerly put it on top and they stand back and ta da they admire their work but what really happens most of the time is that ta da turns into an uh, oh, because the weight of the marshmallow causes the entire structure to buckle and to collapse so there are a number of people who'd have a lot more uh oh moments than others and among the worst are recent graduates of business school they lie they the cheat they get distracted and they produce really lame structures and of course there's teams that have a lot more tadas structures and among the best are recent graduates of kindergarten it's pretty amazing as peter tells us not only do they produce the tallest structures, but they're the most interesting structures of them all so the question you want to ask is how come why what is it about them and peter likes to say that none of the kids spend any time trying to be ceo spaghetti ink right they don't spend time jocking for power, but there's another reason as well and the reason is that business students are trained to find the single right plan right, and then they execute on it and then what happens is when they put the marshmallow on top they run out of time and what happens it's a crisis sound familiar right okay what kindergarteners do differently is that they start with the marshmallow and they build prototype successive prototypes always keeping the marshmallow on top, so they have multiple times to fix in and build prototypes along the way so designers recognize this type of collaboration as the essence of the iterative process and with each version kids get instant feedback about what works and what doesn't work so the capacity to play in prototype is really essential, but let's look at how different teams perform so the average for most people is around twenty inches business school students about half of that lawyers a little better, but not much better than that kindergartens better than most adults who does the very best architects and engineers thankfully thirty nine inches of the tallest structure i've seen and why is it because they understand triangles and self reinforcing geometrical are the key to building self reinforced stable structures so ceos a little bit better than average but here's where gets interesting if you put an executive admin on the team they get significantly better that's incredible you know you look around you go that team's gonna win you can just tell beforehand and why is that because they have special skills of facility they manage the process they understand the process and any team who manages and pays a close attention to work will significantly improve the team's performance specialized skills and facilitation skills of the combination leads to strong success if you have ten teams that typically perform you'll get maybe six or so that have standing structures and i tried something interesting i thought lits up the anti once, so i offered a ten thousand dollar prize of software to the winning team so what do you think happened to these design students? what was the result here's what happened not one team had a standing structure not one had if anyone had built say a one inch structure that it would have been taken on the price so isn't it interesting that high speaks have a strong impact we did the exercise again with the same students what do you think happened then so now they understand the value of prototyping so the same team went from being the very worst to being among the very best they produced the tallest structures in the least amount of time so there's a deep lessons for us about the nature of incentives and success so you might ask why would anyone actually spend time running a marshmallow challenge and the reason is i help create digital tools and processes to help teams build cars and video games and visual effects and what the marshmallow challenge does is it helps them identify the hidden assumptions because frankly every project has its own marshmallow doesn't it the challenge provides a shared experience, a common language common stance to build the right prototype and so this is the value of the experience of this so simple exercise and those of you who are interested in me to go to marshmallow challenge com it's a blog that you can look at how to build the marshmallows are step by step instructions on this there are crazy examples from around the world of how people tweak and adjust the system there's world records that are on this as well and the fundamental lesson i believe is that design truly is a contact sport it demands that we bring all of our senses to the task and that we apply the very best of our thinking, our feeling and our doing to the challenge that we have at hand and sometimes a little prototype of this experience is all that it takes to turn us from an o o moment to a tada moment and that can make a big difference thank you very much。


大家好,我是庄文琪,总有同学私信意面怎么摆盘才好看?那今天就教大家两种意面摆盘的方法。 首先准备个长镊子,把意面卷在上面,用筷子叉子也可以卷好,先倾斜放在盘子上,慢慢竖着,抽出镊子,调整成小山的形状。顶部放个可食用鸡蛋, 打少许黑胡椒和帕玛森粉,点缀些装饰叶子。第一种,堆高意面摆盘就做好啦, 接着做第二种,先把锅里意面归笼好,夹起抖掉多余意面,慢慢卷起来,平行放到盘子上,扶着尾端把镊子抽出,稍微调整一下表面,撒干辣椒末,点缀些装饰液,提升视觉 效果。随意淋少许橄榄油,放上煎好的培根碎。第二种,长条形意面也完成,刚开始上手不容易,大家要多多练习。今天的乐逢法餐小课堂就到这里,你学会了吗?

大家好,我们现在讲一下中国图学学会第十六期全国闭幕技能等级考试一级的第三题。用体谅的方式创建高塔模型, 为标明尺寸不做要求。呃,然后模型的话以高塔加考生姓名来进行命名。这里的话给出了一个立面图,以及啊四个平面图。那这四个平面图分别是给出了这个体量的一些呃,俯视图啊,其实就是他的 这个模型线的轮廓线。那么其实这个题我们仔细观察的话,呃,首层至二十六层,他的这个,他这个俯视图,跟啊跟这个二十二 二十七层到三十六层的平面图啊,他们形状是一样的,只是有一些啊,尺寸不一样。所以你看到这个题,我们应该要想起要把底部这个 这个这个这个,呃,模型线画完之后,然后我们啊把它复制到二十七层啊,或者说复制到他顶部的二十六层,然后再用这个缩放的魅力把它缩小。 好,我们就这么做啊。那我们首先啊,我们按照这个立面图的要求,给他创建这几个标高。好,我们打开软件,我们选择新建,新建的话是用这个。呃,我们新建是用概念体量选择公制体量打开。 打开软件后啊,我们把需要用的视图点开立面图三维图。我们来到标高一。呃,这个标高啊,对我们标高一的话,呃,先不进行画图吧,因为我们先来到难立面啊,给他创建几个标高啊,选择这个标高一, 我们选中这个标高一啊,选中这个标高一,然后对他进行复制,从底部往上啊勾可以勾选,勾选多个约束, 然后往上进行复制。我们看第一个距离是呃,十万零四千的啊,十万零四千, 然后在下一个间距哎,四万,再来一个四万, 呃,然后就是两万八千, 两万八千好,我们画出这个两万八千之后,后面的标高其实呃,其实可以不用做了啊,其实可以不用,就是这上面这个尖尖啊,因为这个尖尖我们啊可以不用去做它。 好。假设就这样啊,我们就画这几个标稿啊,觉得好看的话,把这个参照平面可以拖上去啊,但是在参照平面在三个系统去拖到吧,选择这个参照平面啊, 然后啊,先解锁,解锁之后把它拖高好,这个方向拖高了,另外一个方向插在平面也是先解锁,然后把它拖高 好,超过这些标高就可以了。然后再锁上另外个叉的平面也锁上好。这个时候我们来来到标高一,这个时候我们在标高一里面啊,去把这个首层 到二十六层的这个啊,平面图给他画出来,我们仔细观察,其实他就是有两个正方形啊,两个正方形,然后正方形相交的地方有这个 半径为六千的一个圆弧啊。所以我们首先啊,使用这个模型线里面的这个外接多边形啊,选择四个边, 然后找到这两个叉叉平面的焦点,然后保持水平,先画水平方向的啊, 然后他的一半的话,你看保持水平方向,他的一半是两万一千,保持垂直输入两万一千,好,第一个画出来,第二个也是继续画啊,保持这个四十五度的这个轻角,然后输入两万一千 看一下啊,这个两万一千,然后这就插上平面就搞定了。然后在每个交叉的就是哪个相交的地方会有这样的一个弧啊,一个圆弧在这里。那我们好,我们直接使用这个 圆心端点弧命令啊,找到圆心,然后拾取到这个啊,一根线,然后输入六千的 一个半径啊,画到这根线啊。好,这个方向也画一次,保持垂直,失去到这个线,就是这个线变成蓝色,然后就可以输入六千回车确定,然后再画下来。好。其他的话我们就可以选中画好的这个弧,选择镜像 实习镜像轴啊,这边有了,另外一边也是一样啊。啊,选中这一根弧,选择镜像实际镜像轴啊,上面这一半就做好了。那上面这一半做好之后 啊,下面这一半其实我们也可以把它镜像出来啊。那我们先对它进行拆分图圆吧,这些直线啊,都要从中间给它拆开,给它拆开啊。拆开之后啊,我们再对它进行修 修,剪好点击修剪,延伸为角。呃,留下我们留下我们这。哎,这个地方少修了一下啊。好。 那么上面这一半就修剪出来了。那下面这一半的话,哎,其实我们看能不能框选住他,然后把这下面这一半直接删掉,然后整个选中上面这一半,然后再使用 镜像失去镜像轴,失去水杯方向的参照平面作为镜像轴,把下面就有了。好,这个时候别急着做他的模型,而是我们先选中他,选中这个模型线,来到立面啊,我就来到哪里面,然后选择复制啊,把它从这个标高一啊,一 是往上进行复制啊,我们这里取消约束啊,勾选多个啊,这里复制完再取消约束啊,再往上复制,再取消约束,再往上复制, 再取消约束,再往上复制。好。我们所有的标高都有了。我们就其实看这里需要几个啊,其实需要四个就可以了啊。我们最顶部这个其实是不需要的啊,顶部这个删了吧, 这上面这个我们这上这上面这个复制多了直接删了,选中他删掉啊,就是最最顶部这个魔性圈本来这个这个 这个标高上面也有个啊,模型线,我直接把它删掉了。好,这个时候我们再来到标高一,那我们可以先 对其进行缩放啊,比如说呃,标高音上面的是最底部的这个啊,最底部这个,然后其他的几个标高,其实我们没有, 我没有对他,我就没有把它显示出来。然后我们给他创建对应的视图,选择视图挪成平面,好把这个 这个式子都创建了吧。然后这里就多了几个标高啊,标高二上面这个模型线,我们看一下啊,选这个模型线,标高二上面的模型线,他的你看这水平方向的这个 这个这个这个角到这个角的间距啊,是一千啊,是一万六千啊,是一万六千,就是从这个角到这根线的距离是一万六千。好,我们我们来画一下啊,我们来 画一下 那数字方向。这这也也有标注啊,这里也有标注,我们选中它,点击缩放啊,点击缩放好,我们 shift 其实我们应该让他往中间进行缩放啊,往中间进行缩放。那中间这个的话我们看找到这个焦点啊,看这个焦点,看能不能找到。 好,我们从以中心为界啊,这边是这个字啊,要给他缩放进来,缩放进来来,找到正确的位置啊。好,我们看我们这里失去过来啊,这个刚好是两万一嘛,点一下鼠标左键,然后再往里面进行缩放, 这个字输入一万六,确定啊,这个时候我们看啊,从这个线到这个线的距离都变成一万六了,这说明就缩放好了。这个第一个缩放好了啊,那我们再来到标高三,用相同的办法 对它进行缩放,你看这个的距离现在是两万一的嘛。我们再选择这个模型线,对它进行缩放。选择 选择这个焦点啊,选择这个焦点,两个插到屏幕的焦点,点一下鼠标左键,保持水平,应该失去到 他的这根线啊,他有根虚线,有根虚线啊,失去到他。点击鼠标左键,然后往里面缩,这个时候再输入一万六千。哎,这个是一万六千吗?我们我们先 现在做啊,做这个图了,不是一万六了啊,是一万二啊,是一万二,差点看错了啊,一万二 确定好。还有标高四上面也是一样啊。选中这个,点击缩放,点击这个焦点好,保持水平到这个位置,点击鼠标左键,再往里面缩。这个时候是多少呢?这个时候是八千五百 啊,往里面缩,保持水平,输入八千五百,我就确定好,那确定一下啊,就这个是八千五百没错。 好,那我们从这里看的话,从三万速度看的话,哎,我们这几个模型线就全部缩放好了啊。所以我们选中最底部这个模型线,点击创建形状,选择实心形状啊,然后我们这里 只需要把它的高改一下啊,看根据这个标高改成十万零四千,改成十万零四千,好刚好到这个标高啊,到我们这个标高,再选择标高。二上面的这个模型线也是一样的啊,重复这个动作, 然后这个是四万回车确定好,还有一个,还有一个也是四万啊,选择这个参照啊,这个模型线啊,这是模型选模型线,选择模型线生成,然后再 好还有最后一个选中这个模型线,创建形状,选择实心形状,输入它的高度,两万八千, 两万八千回车确定好。最后我们再画他顶部的这个顶部的这个尖尖,这个尖尖的话,我们相当于给他旋转出来就可以了啊。好,我们来到栏里面 找到这个位置,选择模型,等模型线里面的这个直线命令啊,直线从这个顶部啊,往上面画,画他的总高度看一下啊,把这几个加起来,一个是 一个是这个一万六加八千,保持垂直等于一万六加八千, 好两万四啊。然后再看上面的这个宽啊,他总的宽都是八百,呃,一边一半,那就是四百。 回车确定,然后再倾斜下来啊,这个倾斜下来我们就要从他底部画了啊,实际上底部保持水平,保持水平啊,然后这个底部的话是四千,四千的一半的话就是两千啊,输入两千, 然后再画上去跟顶部这个四百这条横线啊,四百的一半,两百这条横线啊,给他相交起来。然后 我们再把这个圆球的形状给他画出来啊,这个这个这个圆球的形状,那么这一部分的话,哎,我们得找到 他的高啊,他的高也就是说在这个标高上面往上这个呃,一万六千。那我们就可以给他做个参照平面,或者做个标高。好,我们再做参照平面算了啊,做个参照平面给他十 取个线,然后偏亮的时候一万六千啊,然后把这个标高五往上面拾取一下啊,然后再用这个 啊,圆心端点弧啊,找到竖直方向线,跟这个叉叉平米的交点。好。然后我们再看他的半径是直径是四千四啊,那半径是两千, 保持可以保持垂直啊。输入半径是两千两百,直径是四千四百吗? 再画过来啊,只要跟这条斜线相交就可以了,跟他这条斜线相交啊,这个就基本上画出来啊。但是我们要对他进修剪,修剪之前的话,先用拆分涂圆,把这个斜线给他拆断啊,拆断了我们再好修剪,选择修剪 命令,上面修剪掉啊,下面也修剪掉,哎,就这么个形状。好。最后切记啊。因为要他旋转的话,我们的这个呃,题量里面还必须给他指定一个转轴啊。我们在上面把这个数字方向随便画一条这个 模型线啊,当做他的这个旋转轴。好,我们这个时候选中这条上面这个旋转轴,这个模型线。呃,再按住 ctrl, 选中这个啊,我们轮廓的模型线。那这个时候再点创建形状,创建实心形状。这样的话啊,这整个模型就画完了。 好,那我们这个图的话,这个提亮模型就是这么这样一个形状啊。最后看一下题目啊。最后看一下题目,我们对它进行命名,名称的话是 高塔加考生姓名呃,然后就点保存呃,高塔 然后加考生姓名,考生姓名就张三好,然后保存 好。那么这个题就讲到这里,谢谢大家观看。
