** I wrote some APL at work and I like historical fiction **
This summer my oldest kid — 8 years old — asked to learn more about programming. They’ve already got about a full time job’s worth of experience with Minecraft’s red stone, Super Mario Maker 2, Logo, and Scratch so I knew we weren’t starting from nil, but, despite having done a bit of teaching about programming with kids in the past, I hemmed and hawed.

奥运乒乓球决赛,为什么莫雷加德的衣服干爽而樊振东却大汗满身?
作为一名纺织品化学工程师,我就从纺织材料这个角度来和大家好好聊聊这个问题。

全篇干货没废话,先说下我个人的3个结论

1)衣服看起来出汗明显≠速干效果差,反而可能更好

2)日标的速干衣标准更适合剧烈运动出汗场景

3)樊振东是真的爱出汗体质

一:速干衣为什么比常规的衣服更加容易干燥?

很多消费者都会吐槽涤纶、尼龙这类化学纤维做的衣服穿起来闷热不透气,但实际上恰恰相反,涤纶、尼龙是运动速干衣的主流材料

在问题开始前,有个核心知识点一定要给大家讲清楚,那就是大众所说的“面料透气”是个非常复杂指标,不是面料孔隙多穿上去透气(直接测试透气性其实是防风指标)。

穿着透气不闷汗的本质, 其实是让面料尽可能的吸收皮肤上的汗水,只要皮肤表面干爽你就会觉得穿着透气我们日常觉得棉T吸汗透气,是因为棉花的公定回潮率有8.5%(100g棉花能吸收空气中8.5g的水蒸气),你可以简单的理解成“饼干受潮变软”的这个过程。

樊振东 0-2 落后选择更换球衣,随后找回状态完成大逆转,更换球衣从战术和心理层面有多大影响?
同为世界排名前十的对手,樊振东和张本智和的差距并不算太大。尤其是在这种巅峰对决中,双方的技战术几乎都是透明的了。即便是樊振东的胜面相对比较大,但是临场发挥的能力决定了这次比赛的胜负。由于王楚钦意外爆冷被淘汰,男单的压力就落在了樊振东的身上。

比赛有悬念,竞争更激烈,观众们才更喜欢看,也更符合比赛的本质。在万千人瞩目的焦点战,樊振东一开始就承受了额外的压力,导致失误不断,两局落后。一方面承受着巨大的压力,另一方面连续两局失利,压力陡增。如果任其继续下去,后果将不堪设想。好在短暂的离场更换球衣,能够暂时的从压力中脱离出来,重新投入战斗。

不要小看这短暂的离开,这几乎是胜利天平的转折点。因为运动员一旦压力过大,就发挥不出平时的水平来的。这也是王楚钦之前失利的重要原因。对于如何缓解压力,最有效的方法莫过于暂时的离开当下的环境。根据心理学的研究,人的压力跟比赛成绩,是呈倒U形曲线的关系。最开始的时候 … ⌘ Read more

2024 巴黎奥运会开幕式主火炬采用热气球点火腾空方案,有什么寓意?
#巴黎奥运会#巴黎奥运今年主火炬是个热气球,很多博主科普说,其灵感来源于蒙戈尔菲耶兄弟的热气球。

1.经济的发展:

他们居住的小镇阿诺泰,当时是法国造纸产业核心,制造业要求他们学习化学。

↳ In-reply-to » Bought a motorcycle this summer, I did not want two cars, and Marlyn would like to have the car more when I'm at work. So I bought a new cheap motorcycle, KTM Adventure 390. It's been 10 years since I last had a motorcycle (back then I had a KTM 990cc). Here I am with my daughter on the new bike :) My kids love to go for rides, so does Marlyn as well, so it's a lot of fun for all of us. Media

@bender@twtxt.net It cost what you mentioned here too, but they had a special discount, and the shop gave 20% discount for all the gear we needed (since I bought the bike + gear for two persons), so all in all I got a really good deal on it. Also interest rate is locked for 3 years (low rate) so that was also a good deal.
I just took the longest time I could on the loan, to have a low price each month, and then i just pay extra whenever I can to get it payed down faster.
Luckily the Marlyn, my son, and my daughter all fit the same gear, so the 3 of them share that, that saved a lot of money too :)

When i met Marlyn (before we had kids) I asked here to go on her first trip with me (I had a bike before I met her back then), and we went on a 2 week ride from Norway to Italy and back (venice) through the alps and all that. Was super fun, and I think it’s pretty cool of her to say yes to a 2 week trip as passenger :)

历代的《三国志》里有哪些细思恐极的细节?
看了一圈没有说三国志12的,三国志12人气这么低吗?补充几句。

1. 高览在本作是单挑王,战法一开无人能制,不愧是“河北四庭柱”之一。如此看来,设计组应该研究过张国良的《评话三国》 。

【The K 聊汽车安全(2)】汽车工程是如何进行人体伤害评价的?
汽车碰撞安全设计主要考量的,就是在发生碰撞事故时保护乘员和行人等道路弱势群体,减轻事故给乘员和道路弱势群体造成的伤害。

我们在上一讲中已经对全球主要的汽车安全法规和C-NCAP类第三方评价规程进行了详细的解读。

The K:【The K 聊汽车安全(1)】带你认识全球汽车碰撞安全法规

不管是什么安全法规,判断安全性能好坏的标准,都是以人为本,从人可能受到伤害的严重程度出发,综合评价,从而给出车辆的安全等级。

那么,如何对人体所受伤害的严重程度进行评价呢?

总体而言,人体伤害一般分为两个评价维度:第一,人体各部位所能承受的机械载荷限值。第二,根据伤害风险曲线来判断载荷作用下发生伤害的可能性。

一般来说,我们按不同的区域将人体的损伤度量区域分为头部、颈部、胸部、下肢。

2.学习完全呼吸法,多深呼吸少浅呼吸;
