What an underrated channel
Comment from : Callum van Heerden

Would Dijkstra's algorithm pertain to the concept of finding the cheapest route from point to point? That only finds the shortest path, but isnt the shortest path usually cheapest?brbrI guess you would need a different Greedy Algorithm for that idk
Comment from : Hasch

nice video to explain a novice about the Algorithms thumbs up :)
Comment from : Chitrank Dixit

I used to always ask how many times i was supposed to "repeat"
Comment from : glub glub

He is killing me when he says "understand" hahha amazing
Comment from : baprejmer

He sounds kind of like Shrek! :-D
Comment from : mayur1234560

Jep!
Comment from : mavinn3000

The shampoo example at the beginning, I think
Comment from : Jaclyn Brockschmidt

what is the differance between wash and rinse?
Comment from : ChunkOfNorris

The example he used to show what a algorithm is was a algorithm on how to wash your hair
Comment from : nickm2137

Wry neck ? He looks kinda stiff
Comment from : CastelDawn

No you can't, not arbitrarily There are algorithms that have been proven to be mathematically undecidable See: Collatz Conjecture
Comment from : J P

and how is it different than other sequential and imperative programming?
Comment from : Chen Sun

I find that once I get my program running I'm mostly out of the woods It's not like Segmentation fault (core dumped)
Comment from : Ferroneoboron

I wonder if it would be possible to subtitle this man, as he has somehow a difficult accent for non-native english speakers Thanks in advance
Comment from : Fredi Vallina

You neglect that software patents are often not to common-sense as going from place to place When fewer people know how to do a thing, there becomes scarcity, which is the source of an economy If the methods for doing something are hard to discover, patents encourage people to discover them for economic gain If done right, this can increase the quality of everyone's life in addition to the discoverer's
Comment from : Nathan Bendich

That's hardly the point

Comment from : Jan Cajthaml

Pfft, most people don't do a good job learning mathematics or physics
Comment from : WintersunForever

Just great, thanks for sharing!
Comment from : Filax Kun

most people dont realy want to either but our schoolsystems all over the western hemisphere are horrible for children indoctrination is the keyword nowadays providing basics and encouraging exploration of talents and interests is completly gone even the existing curiculum is based on minmaxing ideology now and i dont see how teaching programing should be mandatory for anybody
Comment from : Zishy

Did this video have a different description 4 months ago?
Comment from : MultiPaulinator

I've always wanted to try 40-year-old Scotch! Is he single malt? Can we keep him?
Comment from : MultiPaulinator

I can finally explain my job to my family with that video
Comment from : Bruno

From reading the title, I assumed this was going to be about 3d generated hair
Comment from : KaslarProductions

Sounded to me like shrek explaining to donkey! :)
Comment from : Anirudh Ramanathan

I love his accent
Comment from : Nine Inch Heels

funny accent
Comment from : CastelDawn

holy crap, I want that orange chair in the background Where can I buy it????!!!!!
Comment from : GAGANBable

That's funny, but the guy seems really smart, an I like listening to him
Comment from : iismitch55

Interesting fact: Given a description of an arbitrary computer program, you cannot detect whether the program will finish running or continue to run forever
Comment from : Delryn

Best comment ever! You win the internet for today
Comment from : Elcrapocrew

where did the "hair" part come in?
Comment from : Spike Spiegel

NOW 2 months after i wrote that, my inbox is back lol! :D
Comment from : HeavenOfGaming

lol nope it did not NOW 2 months after i wrote that, my inbox is back lol! :D
Comment from : HeavenOfGaming

I've got this crazy video bar on the side of the video and it won't disappear
Comment from : Jonathan Weber

Put subtitles on these videos please
Comment from : Primus Productions

They should,
Comment from : Primus Productions

I expected Computerphile to have English subtitles like Numberphile because I can't hear you clearly I'm not a native English speaker
Comment from : Chanchana Sornsoontorn

but some extra footage for more advanced people would be great
Comment from : R4stafa

nevertheless, they should
Comment from : spj

Sounds more like Galloway to me
Comment from : Scotty

I envisage this man would be a regular here :) one would hope
Comment from : daedra40

I think the analogies were a waste of time Explaining how to make a set of instructions to sort a series of numbers would have been much more instructive, while still being something that most people could follow And the real meaning of cost and performance would have been easier to illustrate
Comment from : Riplash

what language is he speaking? it sounds interesting i wanna learn that language
Comment from : scikick

Tell him to look at the camera instead of you :D
Comment from : Ben Anderson

why is there so much line bar paper floating around lol
Comment from : treaps

I would've said Billy Connolly lol
Comment from : InfinityDz

Well, if they suddenly start explaining code to people not knowing any of it, it would be meaningless But yea, people who can actually understand that will love it :D
Comment from : Soumya Pattanayak

This is only an introduction
Comment from : Jay Wilkins

If you are learning algorithms it is exactly like a math class! (complete with proofs, yay!) If you are learning programming, not so much There is a difference between the two
Comment from : Jay Wilkins

This is a channel run by numberphile
Comment from : Simon Burgess

Scottish accent Gonna guess Glasgow but I'm not all that good at getting it down to areas within countries Am I right? :)
Comment from : SlimThrull

saw your comment and LOL'D
Comment from : invertedpixel

Mono is an implementation of the Net Framework that is cross platform C# is a much more powerful and unique language than most give it credit for It may have started out rough, but it's matured nicely But like I said, without the tight IDE integration it can feel awkward to work with MonoDevelop is pretty close to VS but still lacks a bit of that integration that makes C# so popular in the Windows world

Comment from : azzburgers

love them accent
Comment from : Anisotropy

Though, I admit, it's a shame
Comment from : Raattis

Most people don't learn programming at school like they learn mathematics and physics
Comment from : Raattis

as a computer scientist i love this channel
Comment from : torosyan

Oh man I can't stand C# though might be because I'm a linux coder ;) I know 16 (not an expert in all though), but I've been doing this for over 10 years so that helps! If you ever want to try something new which isn't your standard sequential language (C, C#, Java, etc) take a gander at Prolog if you haven't already It's quite a fascinating language :)
Comment from : psychovez

Imho I don't think so Being an experience programmer myself, I have preferences to certain languages, but a favorite? The languages are but tools and you need to pick the right tool to suit the job Having a favorite is biasing yourself towards using that one all the time and I've seen many Dev's fall in that trap "I'LL SOLVE EVERYTHING WITH JAVA!!" I personally have a preference for python, C and ASM, since I know them very well But lets say I want to do complex math, well haskell it is
Comment from : psychovez

That's like asking a mechanic which screwdriver is his favorite
Comment from : psychovez

I ignore instructions :P Also every shampoo bottle I've seen says repeat as desired or something like that :p
Comment from : Zukaro Travon

I'm expecting this to go deeper as they cover the subjects Got to start somewhere
Comment from : Lan Sandwich

That is who runs this channel And if you are being sarcastic, don't hang around these channels, they are meant for education, not your sarcasm practice
Comment from : Jared Bennett

The guy that runs Numberphile should take over this channel He's do it better
Comment from : BON3S McCOY

This is like having computers explained by Scrooge McDuck
Comment from : arleas

Can you do an episode about P vs NP?
Comment from : Caffeinated Code Monkey

The title to this video isn't very informative - I would suggest "Just what is an algorithm?" Great video!
Comment from : Sylvielmna Zjsch

How about doing some short video's on specific algorithms and design patterns?
Comment from : noxure

It's "Repeat as needed"
Comment from : immasmashyourface

This an introduction, they still might go into the specifics in a future video
Comment from : Martin Zhang

so?
Comment from : FappyGnome

well clearly you do understand his accent
Comment from : TheJaredtheJaredlong

"while alive breathe" describes the dependency between living and breathing backwards
Comment from : TazG2000

I like the concept of this channel and the first videos seem to be extreme basics, which are needed, but later on, could you guys go more in-depth?
Comment from : Guraski

okey? okey? okey? okey? I've seen thing you wouldn't believe okey?
Comment from : Jan Cajthaml

love this new chanel
Comment from : Car R

It's really funny to hear that as a German; it sounds like a old north german dialact^^
Comment from : Hypatia Secunda LB Svaira Sophia Diotima von Sva

Dwarven English :D
Comment from : MK Warlock

he's speaking English
Comment from : TheJaredtheJaredlong

Computerphile? Like numberphile, but with computers?? :DDDDDDDDDDDDDD
Comment from : Taking1n1

Multithreading! Yay, there's the solution ^^
Comment from : Levi G

Lather Rinse Repeat As a Computer Engineer, I actually used to wonder, why should we repeat it and till when is it supposed to be repeated Stupid instructions :|
Comment from : Copper

Just throw in a simple control variable below the function, and remove the recursive command (as well, so your hair doesn't stay wet forever)
Comment from : Stained Shuriken

I was actually kind of bummed I was hoping to see some info on actual algorithms for physics based hair materials in regards to computer graphics :(
Comment from : name

Fully agree Baby steps Back when I started college for my Computer Science degree, this was the first this they told us when we started programming
Comment from : name

This is good But I like Hal Abelson's (MIT) what is computer science lecture Its available in youtube Its also designed for non-technical audience It contrasts declarative vs imperative knowledge to make people understand what is an algorithm
Comment from : zenerd

For anyone interested in more in depth algorithms I suggest you check out Week 4 of CS50, some minor C experience is pretty much mandatory though
