Mathematics are the result of mysterious powers that nobody understands, and which the unconscious recognition of beauty must play an important part. Out of an infinity of designs, a mathematician chooses one pattern for beauty's sake and brings it down to earth.

Programming is just recursion a lot of the time, so I think it's the most important concept for programming.

[@chris-pee]

Small correction: the Big O notation doesn't specify how fast something is. A constant time complexity of O(1) doesn't mean that the operation/algorithm is fast, but that the speed is constant as the input scales. As a consequence, an O(n^2) algo can be faster than an O(n) algo, for some range of small inputs.

[@pawer122]

Besides this notation is overly used and too often big theta and big omega notations are omitted. Big O is the worst case scenario complexity, it does not make much sense for algorithms which don't do conditional breaks and skips inside a loop.

[@markpeschel8958]

@@pawer122 That's not quite true. You're right that O(f) is an imprecise "worst case" complexity, but not because some algorithms can skip conditionals or loops. O(f(n)) means precisely "the set of all functions g(n) such that there exist some constants c and n0 such that, for all n >= n0, f(n)

I hated math in school, I avoided learning complex equations and algorithms when first learning to program, but once I saw a few of Sebastian Lagues videos where he does stuff in Unity, and started messing around with equations and learning to translate them from paper to code, I literally began to feel like I'm casting magic. Its so amazing what just a few dependent variables can change

Some people require an actual use case for their brain to be willing to learn something. Which is a shit thing to have in school, but it is what it is.

[@Bluemoon_wav]

@@ChivGmailI am that kind of person, also same with math I literally swore to never do math again since high school, here I am happily binge watching math related videos

[@ChivGmail]

@@Bluemoon_wav I feel like a lot of interesting subjects are ruined by our current educational system. Our system isn't about learning, it's about seeing how good you are at forcing yourself to remember stuff you're not interested in.

[@do_not_at_me_bro]

​@@ChivGmail I agree. A person cannot simply retain a textbook of information at all times, the amount of information we retain are limited to capacity and how long we can retain that information for. As the environment and times we are in changes, so does our selection of information that we retain in a given place at a given time. The only information we retain is that which is most relevant to our situation and where our attention is focussed. While I am driving, I do not retain the words Shakespeare invented, because that information is not relevant to the situation I am in. When you go to a library to study a subject, you select books that are relevant to what you are studying. Yes all that information is stored in our memory like books in a library, but the point is our brain selects information from that memory that is relevant to the situation a person is in, the time and place and the environment. I could explain on more levels like how the retained information can be compiled to make a plate of decisions to choose from, and how we can assess those decisions before making a judgement which would cause us to do a thing, but I'll leave you with this thought. Humans learn by their own sensemaking.

[@eliavrad2845]

4:10 In math it's more common to use a different base (ln(x)), but it's easy to change by multiplying the result by a factor, so it's not really important if you're working in base 2, 10, or Euler's number.

[@ladymercy5275]

Log base 2 of x is ln(x)/ln(2). Log base 10 of x is ln(x)/ln(10).

[@eliavrad2845]

@@ladymercy5275 Yep! and for completeness, ln(x) = log10(x)/Log10(e). This means that an algorithm which is O(n log10(n)) is the same as O(nlog2(n)), because nlog10(n)=nlog2(n)/log2(10), and we ignore any constant factors in O notation O(Cn)==O(n). When we want to look at an algorithm, we can choose whichever base is most convenient, like using logarithms in base 3 to describe a tree with 3 children per node.

[@obviouslyblack]

yeah. base e stuff is MUCH more common in math because it was discovered through math itself and has a ton of beatiful properties built in. base 10 stuff is there for just for convenience of humans who count with 10 fingers and base 2 stuff is convenient for computers that count with on/off switches.

4:56 Set Theory is one of the foundations that enable defining the continuous structures of geometry, topology, and calculus.

When you explain base 10 to begin explaining how bases in general work I think it might be better to think of it as each place's decimal value is equal to the number in that place which is less than the base value(10 for decimal) multiplied by the base to the power of the index(with this index starting at 0). This explanation should be easy to understand for programmers since any programmer should understand indexes that start at 0. To express this briefly you can say the decimal value 'D' is the place value 'P' multiplied by the base value 'B' to the power of the index 'I' or D = P*B^I. This is how I like to think about this and it works for any base. EX: for 1011 we have a base value of 2 and index 0, 1, 2, 3 from right to left. to get the decimal value we have D=((1*2^0)+(1*2^1)+(0*2^2)+(1*2^3)) = (1+2+0+8) = 11. Hopefully this helps someone and makes sense.

If you can grasp the concepts, you're a good way into passing maths. Most people who "aren't good with maths" have an aversion to it that holds them back. Get past that, study until just one thing clicks and realise that you were never bad with maths to begin with. The thing is: everybody's starting point is different.

Depending on what you want to do with programming you may not need most of these concepts or you may need much much more than that. Programming is a vast field.

The first ever video I have watched at velocity x0.75. And going to watch again. Bravo!

[@rabik_dev]

Using logs to explain logarithm, brilliant ❤

[@madhououinkyoma]

Took your comment for me to realize 🤣

[@lasham111]

Fireship actually have ability to convince me that I need certain subject or tool for my career

[@abdelsamie.bousba]

Wow, you will be VERY familiar with all of these concepts if you got a CS degree, I got one and now and only now I understand why we get to know those concepts, thanks.

[@A.Belkhir]

i can't believe how great your videos are as physicist we learn some similaire, we basically learn same maths the difference is in the amount of focus on those sub-section just wanted to point one thing which is in linear algebra you skipped one level which is tensors. good luck and keep up the learning and sharing

One of the best fireship video!

[@siphamandlambokazi331]

Broe, I wish I had you as my math teacher, you make it so simple!!

[@giovannironchi5332]

I am a math teacher in a high school teaching to students studying informatics curriculum. Thanks a lot for this one!! 🙏🏻

[@fbodirector7464]

This may be the best maths for programmers video I have seen so far. Surprisingly detailed for how quickly and consistently you go through each concept.

[@cielolov2356]

Thanks for your dedication ant effort for this kind of videos!!

[@k_klaffi1900]

That was probably the most useful and educative video I've seen so far

[@badhbhchadh]

joins are NOT set unions/intersections. In particular, the way you displayed left/right joins would mean they just return the original tables, which is obviously not the case. SQL *does* have UNION and INTERSECT operators for queries. But an INNER JOIN e.g. is the graph of the relation defined after the ON, and the other ones are unions (!) of the latter with elements of A x {null} or {null} x B

[@HolyRamanRajya]

Keep in mind tho, the practical realizations are not always consistent across all DBMS and versions for ANSI SQL. I had the displeasure having to work with a version of OracleDB that was made during their transition to ANSI and results were often ridiculous and an approximation and extensions of their bad non-ANSI Join operators(+,-).

[@passportbro904]

Great video, im gonna learn all of these concepts in 10 minutes with notes each using chatgpt and put it on my resume, if i get a job where i feel ill need it, at least ill know the concepts at least.

[@DiegoBM]

Could you please provide your favourite sources/courses to learn those topics? In particular statistics. Thanks! Great video!

[@johnplays9654]

Chat GPT can decrypt the message instantly. It also explains that it is encrypted in Base64 which is a common encoding scheme used to represent binary data in ASCII format. It even corrects misspellings in the encryption.

[@slowgoins]

I used basic differential equations all the way through my PhD. But if I’m not using particular maths a lot then the core of the concept may not stick. So I love watching other people explain math concepts and you made byte binary make concrete and intuitive sense. Loved the idea of thinking of it as each position is a yes or no at a power of 2 and adding the result.

[@ironCheval]

Literally explained the most confusing part of binary to me in 10 seconds. Finally made the connection lol. Thank you!!!

[@marckraw]

This is so good, it's like a math teacher is actually trying to teach you something instead of flexing his math muscle :D

[@deepjoshi356]

Linear algebra for RSA. I think linear algebra is more related to AES.

[@d3line]

Yup. Cryptography in general is mostly number theory, specifically finite fields.

[@danypell2517]

Diving deeper of the harder topics here would be nice, like a 15 minute linear algebra video or something

[@Dragonaud]

You are true chad of explaining things. Good job as always!

[@UltraMaXAtAXX]

Small nitpick: linear regression isn't just for lines. Fitting a polynomial or some linear combination of functions makes it linear in the linear algebra sense.

[@krast0gaming40]

I am amazed by how programmers are still avoiding math.

[@russianvideovlogguy]

I don't think they do tho

[@mrgalaxy396]

The ones that don't have a formal education in STEM fields, yeah. The rest of us didn't have a choice when it came to learning the math bits haha It's a shame though, because math is so incredibly useful and honestly very interesting when you strip away all the formalities and focus on the concepts themselves. That's kind of the problem though, math isn't really math unless it's strictly formal and the formal definitions often don't make it obvious what they actually mean in a practical sense, which prevents people from seeing the bigger picture that is so valuable. That's why many people get turned off by it, if you don't have a good teacher or do your own research you lose the value in the noise of the formalities.

[@herikaniugu]

Only game dev and data scientists love math

[@elitegamersiddhu5684]

PLEASE DO MORE VIDEOS LIKE THESE. Maybe dive deeper in the chapters shown in this video, it will be extremely helpful. For someone who wants to slowly start learning about neural networks, going to 3Blue1Brown and watching their series can get overwhelming due to so much maths on screen, ur graphical and creative methods are much less brain loading.

[@nandantyagi]

U killed it Fireship! C ur using AI to level up. Well done...inspiring.

[@landotter]

I wish I knew more about all this years ago.

[@devon9374]

So you know it now or will you say the same thing again in 10 years 🤔

[@TheGuyvatzian]

Small nitpick: RSA doesn't involve linear algebra at all. I think you might have meant to say AES instead, which represents the data to be encrypted as matrices and involves matrix multiplication in the MixColumns step

[@jasdfpasdfakdsjhfa]

Yeah was thinking the same. Number theory would've been a much better section title.

[@IvanDimitrovDimitrov]

Thank you very much for this video! As usual you delivered the right amount of information with the speed that my brain can understand and not understand at the same time. I am not a programmer ,but recently I started working on a problem to predict the results of soccer matches using customized knn algorithm with bootstrapping. basically I label the homewin draw and away win in three label 1,2 and 3 of my custom database that I created .What I found out is that with the usual databases I can't get it to more than 21% accuracy,but when I created the database and included the parameters that I think are relevant for football I managed to get it to 51 percent . Do you think I should use another algorithm to boost It even more . So far I have inputted almost 500matches in the database it's a long process but I think it will be worthy.

Mr. Fireship, forget math. You are magic. I have hated math since I was 7 but you just lit up a flame in me with this video and every other video you make!
