Wow I'm amazed I got all of this. I'm so far removed from my academic days. Thats a credit to the writing, interesting and informative graphics, and most of all the skill and engagingness of the presenter. Well done!
I watched this for the first time a little too drunk to really understand, but I'd like to explain what I learned from this: Nature is really, really smart. Well done natural selection.
Great work! I like your pace it is exactly the type of fast action crash review to get rapid conceptual understanding. I'm reviewing 10 per day. I took 1st year physics 20 years ago and I'm not interested in the details, but the conceptual underpinnings. I hope you go right into more advanced topics.
Sheah right like someone can hold a College Physics Book with just one hand in a angle where they could have a page open to read to find out near point
My near points for both of my eyes seem to be at about 12 cm. But I'm not nearsighted, at least not in my dominant eye. And even my weaker eye seems to be less nearsighted than the eyes of most people who wear glasses. I feel special. Maybe that's why I'm so good at finding four-leaf clovers.
What an excellent video. Engaging and validates all with mathematical proofs. Just one errata: at ~7:20 the presenter incorrectly describes reflecting telescope mirrors as "convex" . Reflectors have concave mirrors. (the post-production test and diagram correctly show convexity). Minor quible. This is college-lecture quality education with practical applications and examples. Subscribe and Like pressed.
5:21 the image used is misleading. Assuming that the lens materials are the same the objective lens should be thinner and have a longer focal length than the eyepiece. The instrument shown would have a fractional magnification. Also, the small angle approximation is only valid when using radians. This would also be confusing to a person trying to reproduce the calculations.
SPECIAL RELATIVITY!!! YUSSS! IT'S ABOUT _TIME_!!! Special relativity is my second favorite x_x XD Yes! I am so unbelievable exited right now. Like, I could not wait for next friday. Like, AHH! LORENTZ FACTORS! TIME DILATION! LENGTH CONTRACTION! DOPPLER SHIFTS!! AHH I legit cant wait. lol

Vittamar Akbin how about you make one yourself and our own way :3 also its read that way to trick you you think it would be 1,2,3,4 but its 2,3,4,1 both tell a different story also the biggest thing is last cause in dream when something really good happens you generally wake up after
You told us we could use angles instead of tangents (small angle approximation), then you went ahead and used tangents anyhow. Why bother with the approximation if you are not going to use it?

Im going to binge watch this Wholeeee playlist as a summer study for 11th grade.
Can you do a mathematics series
Bryson Handy no

These physics videos are a lifesaver! Thank you!!!

At 7:08, you say, "These mirrors are convex," but the mirrors you are referring to, primary mirrors in telescopes, are actually concave.
At 7:08 you said these mirrors are convex but they were concave.
Gr8 vid btw
I am learning optics and I watched 2 Crash Course videos about optics. They were very supportive! Thanks!!
Thank you for being so much nicer and more insightful than my real physics professor. TRULY you are the reason I am passing.
wow. visual aperture. such reflection. much refraction.
This is how you teach physics . i just loved it .....
me: this looks like something for kids. Ill understand it.
*ten minutes later*
me: wut
This is amazing! Can we do an organic chemistry course?
I love her accent
I SERIOUSLY LOVE YOUR LECTURES AND SHIRT
Sheah right like someone can hold a College Physics Book with just one hand in a angle where they could have a page open to read to find out near point
Did anyone else see ET when she was talking about subtending?
Very Helpful video since i study some optical physics.
OMFG BEST THUMBNAIL IVE EVER SEEN
nice explanation
Could you please make a video on the basics of Particle Physics?
Wow much doge. Learned much. Eyes blurry.
Takes me back to 2010.
would you do an episode on the physics of radars (for example: weather radars)?
nice presentation!!
Do a video about electromagnetic waves and spectrum please
I love it when I see ads for Crash Course when I am actually watching there video...
This video was proceeded by an advertisement for Crash Course. *Crashception.*
Ceprashashion
Cepcrashishification
Crashsepciption
Preceded
Good video thanks
Thankyou teacher
Thanks a million !
best physics teacher!
Such wow! many education. so phisics
Great Video. And many thanks for speaking bit slow and pronouncing the words completely unlike previous videos :) Good accent btw

Such Episode
Much Science
Very Smart

Nice video but i think you missed the important derivation of magnification i.e m=V/U(1+D/F) where D is the least distance of distinct vision.
I just got an add for crash course on this video
Coooool! I love physics, thanks!
I need a video on tension!!!
Shouldn't tan(theta')=Height of the virtual image/focal length of the eyepiece?
I agree!
She IS so freakin beautiful :(
the emphasis should be on "so" or "freakin" instead of "IS"
Nope
Much beautiful. Much Wow. Wow
No
Is she Southern Indian? I am unsure
That moment when you have astigmatism so nothing looks clear 😂
*POOFFFTT*
That was the sound of my mind being blown
Hope they talk about shadows and darkness.
What exactly is used to absorb photons in digital cameras?
Me eyesight is better than 20/20, my Optometrist said my eyesight is 20/12!
Two Of The Recent Videos are not Added To Physic Playlist
Episode 40 and 42
Do another medical series
Pedant here, is a camera the "Reason" we can see you?
Surely it is the tool used to capture the video, the reason is something else?
The reason is clearly because of the big bang; or whatever happened before it.
SPECIAL RELATIVITY!!! YUSSS! IT'S ABOUT _TIME_!!! Special relativity is my second favorite x_x XD Yes! I am so unbelievable exited right now. Like, I could not wait for next friday. Like, AHH! LORENTZ FACTORS! TIME DILATION! LENGTH CONTRACTION! DOPPLER SHIFTS!! AHH I legit cant wait. lol
Because even if you've never picked up a camera or a smartphone in your life, you're "probably" still using your eyes
Hey guys, look at the moon at 3:49- Spielberg would be proud
I want to help crash course by making videos like them I was thinking Math?
How to
James Soe I was thinking Math SUX!!!
Do you guys have a book i can download
Am I the only one who noticed that she never blinked when talking about what we learnt today.
Don't forget about astigmatism
anybody notice the hagrid on the moon 3:48
I think that's E.T, but well done for spotting it.
Optical instruments? Optican approves this message.
3:49 ET phone home
you took a picture of a *mongrel*
you end up with a picture of a *doge*
what sorcery is this?
a *donge*
YUP
Is it your guy's goal to take everything we learn in highschool and put it into video form?
Lol, people hating but the doge is the only reason I decided to watch this video xD
Nice thumbnail...such dank meme.
Where's the #40 episode?
Did anyone notice the man riding a bycicle at 3:49
look at the moon
1:31 to a physicist:
eye, eye, eye, eye, eye. All eyes.
In India hyperopia us call as hypermetropia
A good video but only a slight nod to Antoine Van Leeuwenhoek which is a pity.
😊
I see red and blue lines
Sorry for taking your opia Shini. I will give it back as soon as I can.
i dont get it :(
Mam can we make telescope at ur home to see moons & stars?
I see everything like game simulation or somhing!
Concave+Bats=Batcave
1. I woke up
2. I gained friends
3. I got a new puppy
4. I won the lottery
(read in the order of 2, 3, ,4 ,1)
the first comment I saw of this was from a person called Rhea Recai if your going to copy mention them plz
I want to see it spread
flutter grace nice to see credit where credit is do
and whats so special about that comment?
Vittamar Akbin its cleverly put together
I think it is just "meh". Why not read it 4,3,2,1? It is not that clever if other arrangements make the same sense.
Vittamar Akbin how about you make one yourself and our own way :3 also its read that way to trick you you think it would be 1,2,3,4 but its 2,3,4,1 both tell a different story also the biggest thing is last cause in dream when something really good happens you generally wake up after
My near point was around 12cm, who is included in the calculation of the average?
I can focus images at 8cm away from the eyes
what if I have astigmatism? My eyes are really crap-I can't see anything close or far away.
I like you more than my teacher 😉
Wow, she's beautiful.
How can you not click on the doge
Where is number 40?
Hold up. Slow it down coach!

hi
This was really really fast
You told us we could use angles instead of tangents (small angle approximation), then you went ahead and used tangents anyhow. Why bother with the approximation if you are not going to use it?
look at the moon
Rip Crash course Physics 😭
My near point (11 years) is 6 cms is that really weird?
Crash course. using memes for learning. good game crash course DAMN IT WHY CANT I TEACH PEOPLE HOW TO PLAY MINECRAFT WITH MEMES!
everything was fine until 6:00 when things got freaky
Why can't my professor explain things this well D:
Ow my eyes hurt now..
Ain't it hypermetropia
isn't this supposed to be #40 instead of#41
