1
So, physics.
2
Ah, right.
3
Physics.
4
Physics, physics, physics.
5
You get into all this?
6
We have been talking about doing Crash Course Physics for a long, long, long, long time.
7
You've wanted it, we've wanted to do it, and now, thanks to our friends at PBS Digital Studios, we're doing it.
8
There's just one thing.
9
I'm hosting Crash Course Philosophy, but I do know someone super qualified for the job.
10
Hi.
11
Hi.
12
This is our host for Crash Course Physics, me.
13
I'm gonna go have a corn dog and host philosophy.
14
Take it away, Shinny.
15
I'm Dr. Shinny Somara, a mechanical engineer and fluid dynamicist by qualification.
16
For the last few years, I've been hosting science and tech shows on TV like Techno, Tomorrow's Food, and The Health Show.
17
Want to know more about me?
18
There are links in the doobly-doo.
19
So, let's talk physics!
20
I love physics, and chances are you do too, even if you don't know it yet.
21
So I'm really excited to host this series of Crash Course.
22
In this series, we'll be covering AP Physics 1 and 2 mostly, but we'll also have a little time for other things along the way.
23
Everything you do, build or say, will be governed by physics, so wouldn't it be nice to read the rulebook?
24
A rulebook that will help you through life.
25
Physics is elegant.
26
It's also practical and fun.
27
Understanding time, position, velocity and acceleration and how they all work together can help you understand your place in the universe.
28
Literally.
29
And I'm sure you've heard of Newton's laws, like his first law.
30
An object in motion will remain in motion.
31
an object at rest will remain at rest, unless acted upon by a force.
32
But what does that mean?
33
And what does it have to do with acceleration?
34
And what are vectors?
35
Scalars?
36
And what does this mean?
37
Kinetic friction and static friction?
38
What's the difference?
39
We'll explain all of that, but what's more special is getting to figure out why understanding these things is so valuable.
40
Understanding how the world, the universe, works gives us a richer and more immersive experience in life.
41
it gives us the opportunity to see the beauty in nature in vast and unexpected ways.
42
Now, a lot of people think physics is hard, but it's easy.
43
Well, as easy as we can make it.
44
So join me, Dr. Shinise O'Mara, this year on Crash Course Physics, which was produced in association with our good friends at PBS Digital Studios.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
