Learn English - Weekly Tip 12 for Chinese Speakers - to fly or to fire kite? (with subtitles) - Duration: 2:12.
Hello everyone, and welcome back to 'One
English Tip in One Minute for Chinese
Speakers (along with its many varieties).'
In these videos I discuss, each week, one
common English mistake made by Chinese
speakers...and this is video number 12.
As I've said before, I think it's a very
smart, cool and practical thing to do to
work to improve your English. In these
videos I show you a slide, and on the
slide there are two sentences: One is the
correct way that someone who speaks
English natively would say it,
the other is the wrong way that many
Chinese speakers might say it. Your
job is to decide which one is correct. So
do that now. Read the sentences,
listen to me read the sentences, pause
the video, think about your answer and I
will discuss the answer in the slide that follows this slide.
So in an ideal world you got this
without much trouble and you can sort of
move on without spending too much time
on it. But it's not an ideal world, is it?
I'm sure many of the viewers of this
video got it wrong, which is not a big
deal all. It just simply means you
have to study. I've given you three
sentences you can study from. It's a very simple
beginning, I know. Memorize the sentences,
review them -- always, always review, it's
very important -- and put into practice
what you've learned through speaking or
writing or both.

Schrödinger equation 6: Exponential function and Imaginary exponents - Duration: 10:10.
Hi!
This episode, we're going to be looking at something that
comes up a huge amount in physics,
especially quantum physics and thermodynamics,
namely, the exponential function e to the x.
Now, don't be frightened. You've already seen it.
I just didn't call it by its name.
It'll help out quite a lot with the notation in the next few episodes
It's sometimes written as exp of x,
usually to avoid having a ton of stuff jammed into a tiny superscript.
It's just another way of writing exactly the same thing.
You might have heard of e as an example of an irrational number,
about 2.718,
and that by putting any number to the power of a whole number
is the same as multiplying that first number by itself,
the second number of times,
and while that's sort of true,
it doesn't really matter here, and confuses things quite a bit.
We're going to start from a more relevant definition of e to the x,
which is that:
e to the zero equals one
and for all values of x, the rate of change in e to the x,
with respect to changes in x, is itself.
In other words, it's derivative is also e to the x.
This may seem like a strange definition,
but there is exactly one function that satisfies these two criteria,
even supposing we don't assume anything about what an exponent is,
and it's actually how e to the x originally came to prominence.
By the first criterion,
the value is one when the exponent, x, is zero,
and by the second criterion,
at that point, the slope must also be one.
As x increases, e to the x increases, initially at the same rate as x,
but as its value increases,
by the second criterion, its slope must also be increasing.
If we take a huge number of tiny steps along,
each time, getting the value, and then updating the slope,
to figure out how fast to go up on the next step,
we can trace out the function.
As the size of steps approaches zero,
the values we will get approach the true values.
We can do the same thing in the opposite direction, to get values for when x less than zero,
just moving down and updating the slope, instead of moving up.
This doesn't work with any other number as the base of the exponential, either.
For example,
the derivative of 2 to the x won't be 2 to the x.
It will be off by some constant factor.
For noise-free quantum physics,
the exponential function is most
commonly used in a very particular way
and we've already seen one we just
weren't calling it that X can be
anything
so if we just replace all axes with
another value let's say five x the
equation should still be true and we get
this this says that the rate of change
in each of the five x with respect to
changes in 5x is equal to eat at the 5x
what's d 5x though
well suppose we start with some value of
x let's call it X 0 and then we add some
amount DX to it
how much did 5x change well 5x starts
out as 5 x 0 and after increasing X it's
five times x0 plus DX or five x 0 plus
5dx that means 5 x increases by 5dx when
x increases by DX
in other words d 5 x equals 5dx that's
just a long-winded way of saying that if
you multiply two numbers by five
the difference is five times larger than
it was
replacing the 5x with 5dx gives us this
so then we can multiply both sides by 5
and get this the number five was
arbitrary so this works for multiplying
X by any value a even if it's a complex
number the case that comes up over and
over in quantum physics is where a is an
imaginary number
like I or negative 7 I but what does
that mean what is e to the power of an
imaginary number
let's suppose a is I since multiplying
by i rotate something a quarter turn in
phase this says that as X changes each
of the IAC's always changes in a
direction whose phase is a quarter-turn
different from the value of e to the ikx
we know that at x equals 0 e to the I
acts will be e to the 0 which is one and
as we saw in previous episodes if you
only ever change something in a
direction that's a quarter-turn
different from its current value it
doesn't change the magnitude it only
rotates the phase at a rate equal to the
magnitude of the derivative which in
this case is 1 Radian per meter since
the magnitude of e to the I ax is 11 x
equals 0 and it never changes its always
magnitude 1 and the phase rotates at one
Radian per meter everywhere
this means that each of the I acts for
any value of x has a phase of X radians
and magnitude 1 if we have e to the ikx
the magnitude of the derivative is k +
the derivative is still a quarter turn
from each of the ikx so the magnitude
would still be one everywhere that the
phase would rotate at k radians per
meter everywhere at position acts the
phase would be KX radians
as you can see each of the ikx is
exactly the starting wave from last time
an interesting property of this is that
since we can reverse the phase rotation
by replacing I with- I and the complex
conjugate of a number just has the phase
negated we know that each of the
negative ikx must be the complex
conjugate of e to the ikx since the
magnitudes of both each of the ikx and e
to the negative x KX r1 and their
complex conjugates of each other
multiplying them together gives the
constant value 1 e to the ikx describes
the initial state of the wave we looked
at last time but we also observed that
the phase changed over time as the wave
move forward since the phase-change by-
h-bar over 2 m times K squared every
second multiplying by time t in seconds
gives the total phase change after time
T combining this phase with the phase KX
from the initial wave means that this
wave function at position X and time T
can be written like this that's super
script is a bit awkward to read so we
can write it using X which means exactly
the same thing as e to the power of the
thing in the parentheses but is easier
to read in this case I sometimes write
at one way and sometimes the other way
depending on how bulky the exponent
books you can double check that if you
plug in 0 for the time one of the terms
disappears so it simplifies back to our
initial wave as i mentioned at the
beginning of this episode this notation
looks a bit complicated but just
remember that whenever you have eaten
the I times anything it has magnitude 1
and the phase is whatever the is x in
this case the phase changes at a
constant rate as you move along X and it
changes at a constant rate as time moves
forward so we have exactly the simple
wave moving forward that we saw last
time
it's just written in a different way
that can be used consistently in other
equations if you remember back
we also found an episode 5 that the
second derivative of the initial wave is
negative K squared times the wave itself
or in this notation the second
derivative of e to the ikx is just
negative K squared times e to the ikx
you can find the same thing by taking
the derivative twice and realizing that
you can take any constant factors from
inside the derivative to outside because
just as we saw before the tip of an
arrow that's k times as long
we'll have to move k times as fast to
rotate the same number of radians per
meter and if the arrow is rotated by a
quarter turn the direction it's moving
will also be rotated by a quarter-turn
if we have multiple variables and we're
only taking the derivative with respect
to one you can just treat the others as
constant values instead of variables for
example these are the derivative with
respect X and the derivative with
respect to t for the time-dependent
solution i glossed over some details
here but I wouldn't worry too much about
them right now we've been using
lowercase K for the angular wave number
in radians per meter when people have an
angular velocity in radians per second
namely how fast something is rotating as
time progresses it's often notated using
the lowercase Greek letter Omega this
wave is rotating at negative H bar over
2m times K squared radians per second so
that would be the angular velocity for
this way we'll be using this notation a
lot in the next few videos because it
will make it much easier to reason about
these waves mathematically when it
starts becoming difficult to visually
follow everything that's going on
see you later

2016 Wasn't That Bad - Duration: 9:29.
Hey y'all
So...
Yeah.
Hey y'all, so, sorry for no video last week
I was busy preparing for two family
Christmases and I was just kinda in this messy state.
So... I didn't really have like a festive video planned,
so I just thought, you know, I'd take a week off.
So excuse me for being a bit cheeky.
I'm not really sure if my lighting's good
'cos I'm at my dad's house, but I mean,
location change! Keeping it fresh on my channel.
Now since this video is going up on the first of--
the first day of the new year,
I would firstly like to say, happy new year y'all!
Welcome to 2017.
And secondly, I would like to say that 2016 wasn't that bad.
For me, you know, 2016 was shit, but...
girl
There were still so many good moments for me.
And, for me, I had a choice of
making a video where I rant about all
the bad things that happened this year,
which I'm probably gonna end up making at some point anyway,
or, I make a really positive video.
My friend Claudia made a video about her feelings about 2016,
especially going into 2017.
That kind of summarises what I think of 2016,
so I'll go link her's down below.
I think that it's important to remember all of the
good things that happened this year.
Don't get me wrong, 2016 was tremendously terrible
but I think that there were some good moments in it.
And I want to share some of my good moments from 2016
to...
I don't know, it sounded like a good video idea.
So this is probably one of the happiest if not the happiest
moment for me this year, well in 2016,
and that was going to see Troye Sivan live.
It was a Tuesday and that kind of...
whole week had been like really shitty.
And it wasn't really something that I was planning to go to,
it was more kind of like something which was like very last minute
because, one of my friends, shoutout to you, Sian
you're amazing girl.
One of my friends was like
'Yo, I got two tickets, you wanna have them?'
and I was like, 'oh my God... God bless.'
So I went with Claudia, and it was just an amazing night
that we both shared and that we both experienced,
and everyone in the room felt and experienced,
and it was... I don't know, it's unexplainable.
So another really happy moment of 2016
was when I asked my to-be boyfriend, to be my boyfriend,
and he said yes.
Side note: Girl, he dumped me like a week later
like, whatever
That moment -- it was like, I remember it very clearly,
it was like a Monday... Lunch time?
I was in an English class and we were like messaging like
back and forth, 'cos he lives in the U.S.
And prior to this, we'd been like messaging like non-stop
for like a week.
And this is gonna sound like
really really cliché but, you know
when I asked him, and he said yes,
like, time just like seemed to stop, you know?
I was like, girl, what is this Maui Wowie
that you got me on, like, girl.
But then of course, he, like, dumped me, and stuff,
but I mean, girl.
Like I've kind of come to understand how much
of like a shitty guy he was.
Girl, I cannot deal with that like, girl, just
Bye!
In the words of Titus Andromedon,
Au revoir les felicias
Bye
Another really happy moment for me
wasn't really one that, when I was like
in it and living it and experiencing it
I was like, oh my God, this is so happy.
But one that I look back on fondly...
one that I now look back fondly on...
If that makes any sense.
But it's a memory that makes me happy thinking back on it.
And that was being in my school's production of
"The Tragical History of Dr. Faustus".
Basically it was in a theatre class,
and we all had to choose two areas of stagecraft.
So I chose acting, 'cos, I'm an actor.
And I also chose sound design.
Acting-wise, I played four characters.
I played the Pope, girl I was the gayest pope ever.
A kind of, like... physical embodiment of, like, lust.
Like, the character was called "Lust", and was kind of like a stripper-esque...
Kind of -- girl, I wore fishnets, it was fabulous.
I also played a scholar and a student.
Music-wise, I composed half of the music for the production
and worked with two other super awesome amazing people
to actually, like, make all the sound,
run all the sound, make sure it all worked for the night, etc. etc.
We were basically like a sound team, like, the three of us.
Ooh shit.
But yeah, obviously during -- it was like a few month kind of process,
but especially like those few show nights,
like I think we did a Thursday and a Friday night,
that was really nerve-racking, really stressful.
But looking back on it now,
now that I know that everything worked out well,
I could say that it was one of
the happiest moments -- the happiest experiences of my life.
I really did enjoy working with those people and, I mean
shout out to all of you, and our fabulous teacher, like.
If y'all are watching, girl I love you.
I think I might be giving away my love too easily.
All well.
This is just a side note
and this isn't related anything to anything in this video,
but I've been watching Shadowhunters on Netflix,
it is so fucking good.
It started off like, it was like this
kinda trashy, like, rip-off of like every teen superhero
TV show or film ever,
but it's, like, really developed into this amazing, really good thing.
I really want to read the books that it's based off of.
And oh my God, I am team Malec all the way, like
Malec is like OTP like
I don't think I've ever had a ship that I've wanted so much
since like ever.
Everyone's like, oh, da-da-da and da-da-da,
and I'm like, yeah, okay, I see it, but
M A L E C
is
*orgasms*
Y'all know what I'm talking about, episode 12,
episode 12... Got me in the feels.
Oh my God, I just remembered this other really fun, cheeky moment.
Basically, my friend and I, we went to
this store, this clothing store, where my
other friend works, and they were working there that day,
and basically, my friend and I who had gone there together,
We like -- we like gave a mannequin a make-over,
we like put on new pants for her
like, put on like a top, and oh my God.
We probably embarrassed her so much (the friend that was working there),
but it was so much fun.
And we almost stole, like, a cardboard cut-out,
this giant cardboard cut-out of like this giraffe or something.
But yeah, oh my God,
that was actually so much fun.
I think you get the point of this video, basically...
Obviously, I come from a place of privilege in that
nothing too drastic happened to me this year
I really want to actively try and make a change
and I think that, you know,
this year was -- this year was crap, this year was
fucking terrible, like, fuck mate.
The Aussie bogan's coming out of me, that's how bad it is.
But at the same time, like,
I learned so many things this year
and I experienced so many things this year
I'm finally coming to understand who I am
and I think that it's important to take those things with me into 2017,
I think that we shouldn't just forget 2016 ever happened,
because so many great things did happen this year.
For me at least, 2017 is going to be
a year of fun and happiness,
kindness, and learning and listening
I think most of all, I really want 2017 to be a year of love.
Girl, I'm tearing up.
As everyone else does, I want the world to be
a better place, you know,
I want 2017 to be a great year,
and I'm definitely going to try my fucking hardest,
fuck, try and stop me girl, like
I'm gonna try my fucking hardest to make it
the best year that I possibly can.
And I know life throws a lot of shit in your way,
but I mean, whatever, like.
Girl, what's new?
But anyways, I hope you all have a really happy New Year,
and a happy holidays, a safe holidays.
And I want you to remember to --
*click*
Stay fierce ladies
Bye.
