Lec 1 | MIT 18.03 Differential Equations, Spring 2006

[kylemichaelbecker]

this guy condescends far too much for my liking

[dirtydan1993]

I wish my teacher was more like this guy. :/

[TurtleboyTom]

I love the MIT lectures and wish I had teachers like these, but this guy sucks.

[devnullnor]

LOL at 22:18. No wonder he has little hair, he scratched it all off doing sign errors.

[carlingbusch]

@devnullnor hha thank you for that

[tadm123]

At 45:41 shouldnt it be x+C instead of XC?

[tadm123]

i wish i had a teacher like him.

[donkaru1]

thank you so much for the video the professor is a pro,,please tell him that i am very gratefull for his lectures,,,so in return let me share an idea that u may already be to familiar with ,,watch all the 34 videos and take down notes ,understand it within 17 days,equivalent of watching and takeing down notes for 2 videos a day,,,,,,so lets see u understand the whole sylabus in 17 days while others take 6 months , just imagine the power,,,i mean the knowledge u will have

[Fickingmit]

It is too coarse to read.

*****

[waterskippers]

It would REALLY be nice if this were reshot in better picture quality.

[XxXxYourselfxXxX]

this is why i am joining the military

[slimjijo123]

u r god to me

[NedraKasifr242]

cool is ja cool

[dnzmaral]

Thanks for video,greetings from Turkey!

[violetmoonster]

thanks for posting this video.

[XYZSagitarious]

Great Teacher he is...... I wish that he is my teacher.....

[frosties01]

I thought people studying in MIT learned Differential Equations in kinder garden

[nicenow25]

@frosties01 Ive watched videos here and at harvard and the way the teach them they prepare them so well for their exams compared to us in the UK. They expect so much here but there they dont. I would love to study there

[flyscrews]

unbeliable, I never looking a lection like this, In italy is for undergraduate

[Gutsyndicate]

I like that he is wrting in big letters

[dearchiv]

I have the following question: Have a look to MIT "Lec 1 | MIT 18.03 Differential Equations, Spring 2006" at the time-point at about 18 minutes and 24 seconds. My problem at this point is not the drawing of a line, where the slope of the function f(x,y) is a constant value named c. My problem is: Why do You call such a line an "isocline" and not an "isoslope"? Thanks for an answer. My e-mail address is webmaster@dearchiv.de.

[mariomaruf]

@dearchiv "Cline" is a root word meaning slope as in incline, decline, or recline. To my knowledge, isoslope is not used as a synonym for isocline very widely, if at all, and all of the textbooks I've surveyed mention isoclines when referring to the method described in this lecture.

[youngdones]

I don't know ANYTHING about computer programming.

[youngdones]

What can you do with a math degree other than become a math teacher at a high school or college?

[yosefbrody]

@youngdones you can plan algorithms useful for computer programming

[finalfantasiest1234]

@youngdones

"What can you do with a math degree."

Well like all subjects in college, there is a division of labor...(dull economics speech)...and mathematics itself is subdivided into various categories. You have pure, applied, computational, and discrete math (which are further subdivided, and further subdivided then)—but I'm guessing you'd be most interested in the second. Applied math is fundamental in most (perhaps all) fields in science: physics, economics, engineering, etc. PM me for more.

[AssassinsCreedVids]

@youngdones Math degrees are ridiculously versatile. They are used in actuarian sciences, technological fields, academics, engineering, finance and business and economics, government jobs, you name it. Math is the language of the universe.

[HJP007]

Differential Eqns. was an easy class even though my professor was horrible. I still wish I studied at MIT :(

[yonatanalemayehu]

Cool 

[MrScanit]

THANK YOUUUUUUUUUUUUU VERY MUCH SIR

[305746148]

what  happen in MIT ???

[LinkEX]

i lol'd at 33:22 :D

[prittwitz1]

Thank you Professor Sturm, sein Lektor war gunstig und gibt mich viel Hoeffnung. Kuessen zur Sein Weisheit!!

[MAZLOTV]

how old are you

[TrollMeTimbers]

@lmarcus461 The underlying concepts MUST be taught before going to real world applications, otherwise the students' creativity and use of the theory will be pigeonholed to what the professor specifically told them what equations to use for certain situations. Your way of teaching would be the death of ingenuity, so don't claim that an MIT professor doesn't have a clue when you don't even know what you're talking about.

[TrollMeTimbers]

@lmarcus461 A thorough understanding of the general theory is necessary to be able to apply it to real world problems without having to be given a specific equation for a specific situation with specific conditions like many teachers do. Too many teachers just give students equations that they don't even understand and say "Here use this equation when given this, use this equation when given this, and use this equation for this problem." What is that teaching?

[njin72]

that's some great chalk

[ThePistin]

I couldn't get enrolled in a university, who cares ?

[purpleleach1]

@ThePistin I wouldn't care at all whether or not you were enrolled into MIT or not; however, I would love to go there for many different reasons. It won't be the end of my life if I am not enrolled into MIT, but it would still be nice to go there. I still have until January to apply as a freshmen in their undergraduate program and will not find out if I'm accepted until much later.

[ParadoxAnonymous]

Great lecture.

I wish I had been accepted to MIT....

[ilya150]

@ParadoxAnonymous

You have.... Just click the subscribe button :)

[Lan5in6]

MIT uses blackboards? pathetic

[pitzi06]

you're a hypocrite.

[FDQureshi]

What is the course book of 18.03?

[FDQureshi]

What is the course book of 18.03?

[Liaomiao]

Is there a lecture on solving exact equations in this course? I haven't been able to find it.

[Liaomiao]

hmm I jus came here after finishing the 18.02 series of lectures. I dont really have any calculus experience other than the 18.01 and 18.02 lectures as well as those calculus lectures from Khan academy which I watched over the past few weeks and understood for the most part. I'm having trouble following the geometric representation of differential equations here. Anyone help me out?

[frostwow]

again the technician ruins a fine show with 15 frames per sec

[CostaDelBarto]

A terrific lecture. Thanks!

[xpplayax95]

damn man I'm 15 and after watching this, I was so confused but inspired to know about all these things

[CostaDelBarto]

@xpplayax95 - awesome!

It's fantastic stuff! Keep having fun and soon it'll be like a second language.

[MashkaZelandiashi]

Pink, or whatever thiscolour is. Pink you got p0wned.

[tripocrise]

22.36 a useful way to make sure if students are awake

[UnitedPebbles]

High school? I learn this in middle school, old man. Ahahaha, j/k.

[wallofsext]

I can't imagine not being able to ask questions and have back-and-forth with my professors. Take the on-screen correction for instance. Many students might not have caught that, whereas in my classes someone would say something almost immediately.

[BYMYSYD]

I'm a computer and i find this lecture offensive

[UnitedPebbles]

@BYMYSYD

YES! and YES! I too found this resemblance of a caveman doodle on his cave with his own poops. Too primitive for computer. For God's sake, man, this is the 21th century.

[jieleazar]

@BYMYSYD you are stupid or what

[19ykcub]

neone else watching this the day b4 a diff. equ. test? lol

[fruitytuterjjc]

(529)^(1/2) people won't know I'm making fun of them.

[sintje21]

@fruitytuterjjc it took 20 seconds to mentally calculate :) :P 20x26=520 3^2=9 your turn to laugh. (23)

[terrencemcg]

@sintje21 i thought he meant the sqrt of 529 = 23?

[xpplayax95]

@fruitytuterjjc haha that was clever

[FacultyBob]

@fruitytuterjjc I see what you did there

[rickyzmkuo]

@fruitytuterjjc the number has remained unchanged for at least 5 months already lol. no people would let you make fun of them any more lol

[100LEGIONS]

@rickyzmkuo Hey let me ask you a question. Can these you tube videos help you out if you are taking a course?

[rickyzmkuo]

@100LEGIONS i personally feel they might since there are some parts that my lecturer did not really go through in detail, and i also find that my lecturer tended to go straight into the algebra and didn't emphasize enough on the geometric interpretations of DEs as what s done in this video series.

[lolololort]

@100LEGIONS

Yes, they can. I just aced my Linear Algebra today with a little help from Strang :)

Dude is a mathpimp

[100LEGIONS]

@rickyzmkuo the course

[ifeanyiboy23]

@fruitytuterjjc LMAOOOOOOOO

[terrencemcg]

@fruitytuterjjc make that 576

[johnsgamestation]

@fruitytuterjjc 23?

[DirtbagEconomics]

@fruitytuterjjc lol @ all 23 people.

[STEVEGET]

dam he got slow, lost his own crib sheet, lol, lolz.

[STEVEGET]

ask him what a minus times a minus =,

ahh he will get confused and think it = nought

[1adnanbhatti]

loool these differential equation like 1st order , 2nd order, 3order differential equation i have solve in eight grade . lol

[astronomy10]

@1adnanbhatti and yet you cant make a sentence with proper grammar

[solchris1]

I have only one word to describe this lecture - WOW!

Love the way this professor teaches and justifies his sentences with examples.

[restorationsanity]

great lecture! if only we could all be so fortunate as to study at MIT

[johntkooz]

@restorationsanity we sort of can thanks to ocw....also this guy sort of resembles phil jackson in an on odd way (maybe a few mannerisms)

[johntkooz]

@johntkooz In many ways there's no resemblance whatsoever, but I just randomly thought of phil jackson, had to be some mannerisms or gestures he used that were mutually similar maybe voice, or something? idk.

[restorationsanity]

lolololol 3:32

"slanty-er" 32:30

[restorationsanity]

lolololol 3:32

[axepuzzle]

insightful and entertaining 

[naturallymagic88]

thank you so much! isoclines are so helpful!!!

[naturallymagic88]

great lecture :) i laughed out loud when he wrote c = -1 instead of c = 1.

[Wigmoso]

even the chalk is better than my uni

[blackphosphor]

bravo to the camera man/woman! very well done in capturing what the professor is focusing on!

cheers

[bmx391xmb]

a little spassy for my liking as a professor. ive only started watching the series though. i liked the 18.01 prof. though.

[MsWtfisgoingon]

this aint for 2006, its for 2003 ! 13:56

[pinkwind0617]

FINALLY script sync begin to work at 7:00.

[adkinsjr]

Around 6:20 he says this is a review of highschool? What? They have diff EQ in highschools? That's wierd. I didn't even take trig in highschool, lol. I just learned that stuff on my own and started with calculus in college. But you don't take Diff EQ until after calc 3.

[kauboibiboppu]

THANK YOU MIT

[vaf88]

i understand this stuff, purdue is okay i guess

[doughauf]

Doug Hauf Start at 15.40

[kadmany]

Now I got a QUESTION

Does this lec supposed to deal with predicitng directions?

Like the direction of an energy field for example?

Thanks!

[zestron]

I don't take math, but this guy seems like an amazing professor

[Zee96969696]

well, i wish i understood what the guy was talking about

[Chaossspirit]

I am so grateful I could die

[mariomaruf]

RECALCITRANT

[elchafa]

The date's wrong, at some point he mentions it's 2003.

Great video, thanks for uploading and sharing!

[GuntaiSama]

Fabuloso, si al menos el "prof" Murillo (ESFM, IPN) hubiera empezado así su curso de EQ.DIF. tal vez otra hubiera sido mi historia en esa clase! jejeje como odie ese maldito librito amarillo que solo se dedicaba a transcribir en el pizarrón.

[yesilful]

Seems only specific schools have courage to put thier lectures on the web.

[wagsman9999]

Just finished this course. I have had the opportunity to view all the MIT math courses - they are excellent, but this one stands out. Prof Mattuck is...well...brilliant. I may even buy his book if I can find the right price. Thank you MIT.

[STEVEGET]

Think of all the money plp waste going to school, with useless teachers and very often liberal indoctrinators

This is better save your money and don't have your head filled with pc mush

[boozman0315]

@STEVEGET Have you ever enrolled with a university? I think if you have you wouldn't say this and my head is not filled with "PC mush" it's all relevant.

[STEVEGET]

INTERESTING

[Yami7761]

a heartfelt happy teacher;s day

[lkbstvxq]

se ve interesante la clase... pero alguien se tomaria la molestia de sub titularlo porfavor ... muxos estudiantes latinoamericanos lo agradecerian... gracias

[Taowhr]

For the world best university for science, they sure got poor recording qualities.

[youngdones]

What kind of careers can an math degree be used for?

[kashmiriguycali4nia]

@youngdones the question is what can't a math degree be used for? an MIT math degree anyway

[lucienshand]

@youngdones

# Astronomy and space exploration

# Climate study

# Medicine

# National security

# Robotics

# Animated films

[abz998]

@youngdones professional wanker?

[birsutube]

I cannot thank MIT for doing this.

And I wish I had a porf Like Dr. Mattuck the first time I took differential equations a decade ago. I learnt (and assimiliated) more from this one video than I learned from that entire course possibly,a t least what I I retain from that class.

[mrsezori]

@ashleylovesdaddy: The thought of things being priceless seems like a huge step in the future and inevitably things will turn out that way when people come to grips with the underlying reasons behind the monetary system. However, with that being said, people are going to always, in one way or another, feel that the knowledge that they retain has some capital value to it and charge extreme amounts for it. Why can't things now be free (food, clothing, knowledge, etc) when it's all received free?

[matandcs]

great channel 

[aurocati]

I know it will sound boring but... the last integral was wrong: he forgot a minus but everything would be the same; I'm not demeriting just notifying.Good initiative and class

[shogun996]

@EasternMerchant. Have you ever just sat there and wondered that the way you believe so blindly in your own religion that you are no different than a crazy Muslim extremist and that in a different set of circumstances you'd be the one with a bomb strapped to your chest claiming it's "God's will."

[TheNova5]

wtf. i just watched a lecture on differential equation but i read comments talking about God. Did we all just watch the same video???!

[ZufuruTube]

That kicks ass! I'm astonished...

[yt1952]

I wonder if lecture attendance of maths students across the world is down because of this lol

[Lolleka]

Anyway, that professor is my favorite person of the week.

[Lolleka]

14:01 -> "[...] This being 2003 [...]"

Title -> "Lec 1 | MIT 18.03 Differential Equations, Spring 2006"

WUT?

[VanillaShoelace]

He says most of the people learned Differential Equations in highschool??? my school didn't even offer calculus!

[horrabletypoe]

@VanillaShoelace Woah, really? I'd say 95% of my peers have a fairly firm grasp of at least basic diff/antidiff, with a reasonable group doing university-level mathematics (vectors, cplx numbers, diff. equations, etc), and I haven't left highschool yet. I can't imagine a year 11/12 math class not teaching calculus; what did your teachers manage to spend all the time on?

[03Kabbotta11]

@VanillaShoelace If your school didn't offer Calculus then that is a huge problem for your school, but when he refers to knowing diff. eqns he just means stuff like,

y ' = 2x. Those are covered in any basic calculus class they just aren't usually referred to directly as differential equations.

You should petition your old school for a Calculus program..it's pretty much....ESSENTIAL.

[JakabBigShow]

@VanillaShoelace he didnt mean differential equations as a course, he meant understood the meaning of dx, dy, integrals etc or basically calculus. He went on to say that if you didnt learn in highschool then you learned in 18.01 which is in fact Calculus 1

[Ljlualmiao]

I like this guy way better than my De-Fe-Q professor.

[sphtut]

MIT forever!

[master308308]

can you tell me on which year of studies students of mit learn differential equations???

[tttybhgf]

@master308308 Probably first. Do you think otherwise?

[ashleylovesdaddy]

This is the beginning of the future of University education. If every professorial lecture was available free to everyone, the entire degree system will have to be revised. I think this is a good thing. No one should be able to own knowledge. It should be available for free for everyone and we shouldn't have to purchase a degree to be qualified for a job. Self-education can be sufficient if one applies themselves. Thumbs up if you want college to be free!

[Iamatheist1234]

@ashleylovesdaddy exactly, and what do you think of the evaluation of the academic performance of individual student? how should they do it?

[ashleylovesdaddy]

@Iamatheist1234 I would say there would have to be Professors as there are now. Their teaching would form the backbone of the next generation of professors. Perhaps a body of educators in a Senate-like structure, but for each area of expertise. Each Professor could be in an apprenticeship under more experienced Professors forming an ever-larger body of knowledge. But a common, long-term goal has to be established for Earth's population. With no common goal, there's no direction.

[Iamatheist1234]

@ashleylovesdaddy interesting, so do you think we should get rid of the degree system?

[ashleylovesdaddy]

@Iamatheist1234 Not necessarily get rid of it. I just think it clearly needs to be readdressed to better describe the level of comprehension a person has in a particular field. I know many people with B.S. in Sociology or various other things that clearly know nothing about the field. I picture an ideal situation would be sitting around the expert, asking questions. Imagine Socrates standing in the middle of the room, surrounded by young disciples which he trains for their whole lives.

[Iamatheist1234]

@ashleylovesdaddy that is an marvelous thought,I am actuall interested in teaching, so I might be a part time teacher in a community college after i get my ph D, the reason I like community college is that students have more access to instructor's assistance and there are more interaction between students and instructor, exactly the kind of education we need, unlike some big U , 1 of my friend actullay had to study online himself becuz there was no room for him to even stand in the auditorium.

[ashleylovesdaddy]

@Iamatheist1234 I think the idea of Apprenticeship needs to be revisited. Maybe on a larger scale. Forging a common human goal will make educational advancement automatic. The only way to achieve anything long term for all of humanity is to educate everyone and give them free creative capability with no limitations. The only think keeping this from happening is...well two things, Money and Religion. Money inspires greed and crime. Religion fights scientific thought and divides people.

[Iamatheist1234]

@LogicalFlawDetector for your information I am major in physics and I am aiming for being theoretical physicist, what is wrong with free social services and education? there are people who long to get an education but is unable to do becuz they are poor(me 2 years ago for instance), faggots like yourself take life for granted , there are a lot of people who are not as lucky as you so suck it up asshole, is not like we are stealing from the government I am preparing myself to serve in the future

[Iamatheist1234]

@LogicalFlawDetector your detector is definitely made in China, why don't you go back to where you come from and let us Americans run our own country. FUCK YOU

[ashleylovesdaddy]

@Iamatheist1234 Your achievements could be measured similarly to how Gamer Points are recorded on modern video games. Imagine earning achievement points for reading Einstein or building your own Tesla Coil. Getting credit for every educational step you take in life and being measured against everyone else. It would be a new form of credit and social status. A number you could flash to identify yourself as educated and worth listening to. Politicians would have to have high numbers.

[Iamatheist1234]

@ashleylovesdaddy omg that's awesome! that's awesome! this idea should totally be heard by the education department! damn!

[ashleylovesdaddy]

@Iamatheist1234 I'm glad you like the idea. I hope you're someone with power that can steal my idea and make it happen. No one ever listens to me in real life. But I get a lot of feedback on youtube and facebook. Thanks for the compliment. What a world.

[Iamatheist1234]

@ashleylovesdaddy mosty definitely, I am into education field and I sure hope people from all over the world can have more access to learning!

[ashleylovesdaddy]

@LogicalFlawDetector I do read books. I don't care about Obama or any other politician. I'd love to go to MIT but I can't afford it. I don't suggest anyone try to do advanced research by watching videos of youtube. I agree there is more to a degree than just a job. I just can't tell why you've decided to attack my thoughts. It was just a comment. You don't think education should be free? Why should only some people get educated? Is it just about the money?

[ashleylovesdaddy]

@LogicalFlawDetector Why are you so politically angry at me? I just think it's a shame there are so many talented people in the world that can't get the education they need because they simply can't pay for it. I have many ideas about how to monitor the level of someone's education electronically. I'm sure you could imagine an Algebra app for example. I take this issue seriously. Please don't attack arguments I'm not making. It just confuses people that may be reading this.

[ashleylovesdaddy]

@LogicalFlawDetector Why would you tell me my comments is moronic? It's just a comment that turned into a little discussion. No one had to respond. And don't tell me what these videos are for. You didn't post it/them. I admitted I didn't understand the content of this. But it's inspiring to me just the same.

[gregor121]

@ashleylovesdaddy

like in germany. I pay nothing, well the small burocratical fee

[RaZuA1989]

@gregor121 :")

You pay taxes that pay for your education. Nothing is free.

[DigtBrain2]

@ashleylovesdaddy getting the knowledge is NOT the problem nowadays - finding the time to really get it is. Mathematics is a great example - it's very easy to find free lectures and books on the intro. stuff. BUT it takes a extreme long time for a normal-intelligent person to get it ALONE. But it's very easy to do in the academic enviroment (lectures, tutorials, exercises, test, learning-circles, assistant/prof.-hours, etc.)

[mystyr0]

@DigtBrain2 I wouldn't say it's "very easy."

[Mrsaysyou25]

@ashleylovesdaddy No offense, buIf every one can get a degree for free, how are professors going to make a living, and the universities? Without income form tuition, professors will be dicouraged from teaching which is definitely negative for further advance of science.

[naturallymagic88]

@Mrsaysyou25 if everyone has an equal opportunity for education, then there will be more people available to advance science :)

[boozman0315]

@ashleylovesdaddy then where is the motivation to teach, fools.

[the0fart0machine]

To solve a differential equation involved the time honoured method of guessing! For a weight on a spring, an intelligent guess suggested a sine wave. I wish I had known this years ago.

[lvngdead]

You can read what he';s gonna say before he says it!!!

MIT is so advanced!!! yah!

[tassaduq009]

@lvngdead hehe future in now

[tassaduq009]

@lvngdead hehe future in now

[tekerirem]

@lvngdead

yea I gave you a down thumb

[muffinod]

Does MIT have some deal with youtube regarding the videos?
