教授会武术，流氓挡不住！ Professor will martial arts,Rascal stop!

　　只见他，左手按砖，右手抬起。手落砖断！川大副教授魏骁勇课堂上这一幕，在网上彻底颠覆了人们对教授的印象。教授不是眼镜和柔弱斯文的代名词！

See his,Left hand to press brick,The right hand is raised.Hand fall brick break!Associate professor su WeiXiaoYong class this scene,In the online overturned thoroughly people to the professor's impression.Professor is not synonymous with glasses and weak sven!

　　而学生们，看了表演听了讲解，对复杂的物理学原理产生了浓厚兴趣。不过麻烦也来了，有人以为他是武林高手，下了挑战书，要一决胜负。

And the students,Saw the show to explain the,For complex physics principle have great interests.But here comes trouble,Some people think he is martial-arts expert,Off the challenge,For a showdown negative.

　

　课堂断砖 学生惊叹 Class broken brick by students

　　讲台上，他操着一口流利的英语教授物理知识，年轻帅气。不时翻动幻灯片，给学生们上课。

podium,He speaks English professor physics knowledge,Young handsome.From time to time flipping slide,Give the students in class.

　　他叫魏骁勇，35岁，川大副教授。

His name is WeiXiaoYong,35 years old,Associate professor su.

　　讲着讲着，他一阵摩拳擦掌后，摇摇头、甩甩脚、掰掰手。“我来表演个单手劈砖……”魏老师要劈砖？没听错吧？同学们瞪大了眼睛，拍起了巴巴掌。

Spoke about the,He was after fight,Shook his head/Jilt left foot/BaiBai hand."I come to show a single hand split brick……"Wei teacher needs to be split brick?Didn't listen to wrong,?Students stare big eyes,Clap up babar palm.

　　魏老师拿出一块长、宽、高分别为20、10、5厘米的红火砖，砸碎一颗核桃，“不会还要用头来检验嘛”。他把砖块放在课桌上，一端留在桌上，一端伸出桌面，脱下外套后，马步扎了不到一分钟，“哈！”随着一声吆喝，魏老师抬起的手臂猛地砍向砖块，砖应声断成两截。

Miss wei took out a piece of long/wide/High were 20/10/5 centimeters of red brick,Smash a walnut,"Won't will head to well test".He put the bricks on the desk,End on the table,End reach out desktop,Took off his coat after,"Ma bu" or horse stance taken less than a minute,"ha!"With a voice call,Miss wei lift arm suddenly cut to bricks,Brick answered and broken into two pieces.

　　哇撒，魏老师真牛啊！教室里再次传来掌声，这位大学副教授，仿佛瞬间变成了武林高手，同学们纷纷围了上来，询问魏老师手有没有受伤，痛不痛。关键是一个子不高、长相斯文的大学老师，怎么能做到单手劈砖？

Wow and,Miss wei the true cow ah!The classroom applause came again,The university associate professor,As if moment became martial-arts expert,The students have surrounded up,Ask miss wei have injured hand,hurt.The key is a child is not high/Looks sven university teacher,How can do single hand split brick?

　　

劈砖 Split brick

　　为讲科学工程实践 Speak for science and engineering practice

　　这是大约半个月前，发生在川大望江校区“科学工程实践”课堂上，副教授魏骁勇运用物理原理单手劈砖的一幕，被同学们拍成视频后发到了网上。视频中， 老师授课内容被同学们翻译成中文，并配有字幕。

This is about half a month ago,Happened in su wangjiang campus"Science and engineering practice"class,Associate professor WeiXiaoYong using physical principle single hand split brick scene,By students made into a video to online backwardness.Video in, The teacher lectures translated into Chinese by students,And equipped with subtitles.

　　“不是功夫，不是娱乐，只是科学，每个人都能做到”。魏骁勇一句话道出玄机，他是综合运用了初、高中学过的杠杆原理和冲量定律实现劈砖的。

"Not kung fu,Not entertainment,Just science,Everyone can do it".WeiXiaoYong word what mystery,He is the integrated use of initial/High middle school the lever principle and law of impulse to realize split brick.

　　把单手劈砖用在课堂上，源于魏老师的一次散步。魏老师告诉记者，现在很多学生都是90后，讲大道理还不如做个实验，让学生们眼见为实，为此他也一直在思索怎样提高教学效率和教学效果。上学期他在校园散步时，看到校园施工场有砖块时，突然来了灵感。于是，他抱了10块砖块回到实验室做起了实验。研一学生张晋说，他很喜欢魏老师的讲课风格，经常很复杂枯燥的原理和公式，魏老师善于用浅显易懂的方式让人快速明白。也有学生表示，以前学不懂时就死记硬背，记得快，但忘记也快。

Put one hand split brick used in the classroom,Miss wei from a walk.Wei teacher told reporters,Now many students are after 90,Speak truth than do a experiment,Let the students seeing is believing,For this he has been thinking about how to improve teaching efficiency and teaching effect.His last semester in campus walk,See the campus construction field when bricks,Suddenly to the inspiration.so,He hugged 10 block bricks back to start the laboratory experiment.Research ZhangJin one student said,He is very like wei the teacher's lecture style,Often very complex boring principle and formula,Wei teacher is good at using a simple way to make people understand quickly.Also have students said,Before learning do not understand it by rote,Remember fast,But forget to also fast.

　　

曾经学过武术 Once learned martial arts

　　走红后有人挑战劈砖 After rising challenge someone split brick

　　视频一出，立即引起了众网友热议。魏老师也很快火了起来，有网友赞叹魏老师真有心。“这样的老师太棒了，上课生动，气氛活跃，老师讲的吸引人，同学们也喜欢听”。视频的评论中，有调侃，但更多的是佩服。目前，这段记载着川大老师劈砖教学的视频，已在优酷网得到了31万的点击率。

　　此外，魏老师的身份也让网友琢磨不透，他到底是大学教授？还是武林高人？魏骁勇也透露了个秘密，他的确会一点武功，但是不精。小时候常利用课余时间，到体校和武术馆内训练，但多是表演类的套路，“花拳绣腿”。2002年开始，他又迷上了太极。不过，他一再强调这和单手劈砖没有关系，因为他没有练过气功。

In addition,Wei teacher identity also let netizen elusive,He really is a university professor?Or wulin superior?WeiXiaoYong also revealed a secret,He did a little fighting skill,But none.When I was a child often use their spare time,To the sports school and martial arts training,But many are performance class routines,"HuaQuanXiuTui".2002 start,He fascinated by tai chi.but,He has repeatedly stressed that this and single hand split brick no relationship,Because he didn't know qigong.

　　甚至还有网友觉得魏老师是世外高人，校园只是他的世外桃源，有网友下发挑战书，想要会会魏老师，比试单手劈砖谁最厉害。

There are even netizens feel wei teacher is a superior,Campus just his xanadu,Have net friend issued challenge,Want to meet miss wei,Have a competition single hand split brick who is the most severe.

　　“比啥武喔，我只是一名老师”。魏老师幽默地表示，他不是少林寺的高僧，只是一名在四川大学任教两年的老师。“我也是接到同学的电话，才晓得传到网上去了。” 成都商报记者 安利平 图据网络视频截屏

"Than what wu oh,I'm just a teacher".Miss wei humorously said,He is not the shaolin temple monks,Just a name in sichuan university two years of the teacher."I also received students telephone,Just know that on Internet went to."

单掌断砖的秘密 Single palm off the secret of brick

　　在于砖的一头翘起一点 In brick of a head tilted a little

　　方法A 砖块全部放在桌面上。这样，手劈向砖块时的冲力，通过砖块形成压力扩散到桌面上，力量分散，不易劈断。

Method A brick all on the table.this,Hand split toward bricks of impulse,Through the bricks formation pressure diffusion to the table,Scattered forces,Split off not easily.

　　方法B 砖块的一端留在桌面，另一端伸出桌面。这样，手劈向砖块时行成“剪力”，把砖块折断，不过这需要很大的力量，一般常人很难做到。

Method B bricks at the end of the stay in the desktop,The other side out of the desktop.this,Hand to make bricks split into"shear",The broken bricks,But it takes a lot of strength,General ordinary people difficult to do.

　　方法C 将砖块的一端放在桌面上，用手按住，另一端伸出桌面，并抬起来一点点。 手劈向砖块时，力量用在砖块抬起的顶部，在最短的时间内以最快的速度劈向砖块。

Method C will be at the end of the bricks on the table,Put my hand on,The other side out of the desktop,And up a little bit. Hand to split the bricks,Power in the top of the lift with bricks,In the shortest time with the fastest speed to split toward bricks.

　　{1}劈末端

{1}Cleft end

　　根据杠杆原理，手掌击在砖块最末端，会产生最大的冲击力

According to the lever principle,Palm struck the bricks the end,Will produce the maximum impact force

　　{2}微翘起

{2}Micro tilt

　　根据冲量原理，砖块要跟桌面有一定距离，这样才能产生更大的力

According to the principle of impulse,Bricks with desktop to a certain distance,This can produce greater force

他还发明“点名系统” He also invented"Call the roll system"

　　拍照就可查谁翘课 Photos can check who to skip class

　　魏老师还研究了一套“点名系统”。运用这套“点名系统”，上课老师只需要对着教室分区域照几张照片，然后将照片上传服务器就完成点名了。照片上传服务器后，会自动拼接成一张大照片，然后系统自动对照片里的学生头像自动编号和识别，与后台数据对比，就知道哪些人来上课了，哪些人没有来上课。“当然，目前的人脸识别的准确率还不能做到100%，加上照片的角度等问题，系统还做不到100%自动识别上课的学生。

Miss wei also study a set"Call the roll system".Use this"Call the roll system",In class the teacher only need to the classroom points area as a few photos,Then will photo upload server can finish a calling.Photo upload server,Will automatically splicing into a big photo,Then the system automatically photos to the students in the head portrait automatic Numbers and identification,And the background data contrast,Know who comes to class,What people do not have to come to class."Of course,The current face recognition accuracy is not to get 100%,Add photos of problems such as Angle,System also do less than 100% automatic identification class students.
