TED英语演讲：每天一秒钟
TED英语演讲：每天一秒钟你的生命中曾经有过很多美妙、欢乐、或伤感的时刻，那么你是如何记录这些时刻的呢? 栗山-塞萨尔导演(Cesar Kuriyama)发起了一个项目，每天都为自己录制一秒钟，记录下生活的瞬间。
Cesar 认为虽然之前有人尝试用图片记录生活点滴，但是视频包含了声音和动作，更加直观生动。
试想一下,如果你现在开始记录生活中的每一秒，20xx年后，你相当于为自己拍了一部约2 小时的电影。
下面是小编为大家收集关于TED英语演讲：每天一秒钟，欢迎借鉴参考。
演说题目：One second every day演说者：Cesar KuriyamaSo, I'm an artist. I live in New York, and I've been working in advertising for -- ever since I left school,so about seven, eight years now, and it was draining. I worked a lot of late nights. I worked a lot of weekends, and I found myself never having time for all the projects that I wanted to work on on my own.我是一名艺术家。
我住在纽约，从事广告设计，从毕业开始我就一直做这行，至今已经七、八年了，慢慢的感觉有点厌倦了。
我熬了很多夜，在办公室度过了很多的周末，我发现自己一直没有时间来做我真正想做的个人项目。
And one day I was at work and I saw a talk by StefanSagmeister on TED, and it was called "The power of time off," and he spoke about how every seven years, he takes a year off from work so he could do his own creative projects, and I was instantly inspired, and I just said, "I have to do that. I have to take a year off. I need to take time to travel and spend time with my family and start my own creative ideas."有一天我在工作的时候看到了施德明(Stefan Sagmeister)在TED上的演讲，主题叫“时间流逝的力量”，他提到他每过七年，就拿出一年时间来休假，抛开工作，做自己的富有创造力的项目，我的思路被他打开了，然后我说：“我也要这么干，我要休一年的假。

毫秒微妙缩写
毫秒微妙缩写【篇一：毫秒微妙缩写】秒（second）是国际单位制中时间的基本单位，符号是s。
有时也会借用英文缩写标示为sec。
国际单位制词头经常与秒结合以做更细微的划分，例如ms（毫秒，千分之一ms（百万秒）和gs（十亿秒），但实际上很少这样子使用，大家都还是习惯用60进制的分、时和24进制的日做为秒的扩充。

radian per second单位
radian per second单位The unit "radian per second" is a measure of angular velocity, representing the rate of change of an angle over time. It is commonly used in physics and engineering to describe the rotational motion of objects, such as wheels, gears, and motors.“弧度每秒”是一个角速度的单位，表示角度随时间的变化率。
在物理学和工程学中，它常用于描述物体的旋转运动，如车轮、齿轮和电动机。
When an object rotates, it traces out a circular path, and the "radian per second" unit quantifies how quickly this path is being traced. Specifically, one radian per second means that the object is rotating through an angle of one radian every second. Radians are a unit of angular measure, and they represent the ratio of the arc length to the radius of a circle.当物体旋转时，它会描绘出一条圆形路径，而“弧度每秒”这个单位则量化了这一路径被描绘的速度。
具体来说，一弧度每秒意味着物体每秒旋转过一个弧度的角度。
弧度是角度的测量单位，它们表示圆弧长度与圆半径的比值。
a second 用法
"a second" 这个短语在英语中有一些常见的用法，以下是其中几种常见的用法：
1. 表示时间单位：
- "a second" 可以表示时间单位，意思是一秒钟。
例如："Wait a second, I'll be right back."（等一下，我马上回来。
）
- "in a second" 可以表示在将来的某个不确定的时间，意思是很快，马上。
例如："I'll be there in a second."（我马上就到。
）
2. 表示次要的或辅助的事物：
- "a second" 也可以表示次要的或辅助的事物。
例如："His main job is teaching, and his second job is writing."（他的主要工作是教书，而副业是写作。
）
3. 表示排名或序号的次序：
- "second" 在这里表示第二的意思，用来表达排名或序号的次序。
例如："She came in second in the race."（她在比赛中获得了第二名。
）
希望以上解释能够帮助到你理解 "a second" 这个短语在英语中的常见用法。

1秒电阻电流
1秒电阻电流
（原创版）
目录
1.电阻和电流的概念
2.1 秒电阻电流的计算公式
3.1 秒电阻电流的实际应用
正文
电阻和电流是电学领域中非常基础的概念。
电阻是电路中对电流流动的阻碍程度，用欧姆（Ω）表示。
而电流是电荷在单位时间内通过导体横截面的数量，用安培（A）表示。
在电路中，我们常常需要计算 1 秒电阻电流。
这里的 1 秒电阻电流，指的是在 1 秒的时间内通过电阻的电流大小。
要计算 1 秒电阻电流，我们需要知道电阻的阻值和电压，然后使用欧姆定律进行计算。
欧姆定律的公式为：I=U/R，其中 I 表示电流，U 表示电压，R 表示电阻。
假设一个电阻的阻值为 100 欧姆，电压为 12 伏特，那么在 1 秒内通过这个电阻的电流可以用以下公式计算：I=U/R=12V/100Ω=0.12A。
也就是说，1 秒内通过这个电阻的电流为 0.12 安培。
1 秒电阻电流在实际应用中有很多用处，比如可以用来计算电器的功率、电能消耗等。
例如，如果一个电器在 1 秒内通过的电流是 0.5 安培，电压是 220 伏特，那么这个电器的功率可以用公式 P=UI 计算，即
P=220V×0.5A=110 瓦特。
总之，1 秒电阻电流是电学中非常基础的一个概念，它对于理解和分析电路中的各种现象具有重要意义。
