I wish to meet all of the people who say "math is useless to programmers"

And give them a day of my current job, for which I am rewieving trigonometry, Fourier transforms, Laplace transforms, studying Clarke's and Park's transforms and generaly banging my head against the whole mathematics syllabus I alread beaten into submission during my Engineering student days (which are long gone and the knowledge faded).

It will depend on what you work with. But I think people that are bad at maths probably make bad programmers, since logics is so important.

Ooh, signal processing? That is cool. Every day is a learning day... recently I had to use Welford standard deviation to calculate a running standard deviation. I did not even know that was possible without storing all of the numbers.

Brushless motor control, which is signal processing (especially when factoring in PWM sinusoids and EM emission control).

Every time I'm asked to do some math, I always start at 1+1 and work my way from there. I always like math at school, got good grades even if I was never really good at it, (or felt like it). Anecdotal, I crapped a test on Fourier Transform in one of our Theoretical Computer Science course, We had to do something with it to reduce some equations, but I indexed one of the sequence at 1 instead of 0, it never converged. :rolleyes:

I think a lot of the time maths is no necessary in much of what we do as developers, but having a mind that is good at maths does seem to make people better developers. Perhaps it's something to do with being able to work with abstractions or recognise logical patterns. P.S. I do not have a naturally good mathematical mind.

It all depends on the field in which you end up. I think all programmers (who do it as a full-time job) end up acquiring expertise in a domain that is not, strictly speaking, related at all to programming. Mathematics would be one of those domains. Personally, I got shafted when I was accepted to university, provided I took a chemistry course, which they had decided was a prerequisite for computer science - chemistry was the only science course I did not take while in high school. To make a long story short, the schedule for that chemistry course conflicted with my other courses, and neither teachers nor university administration gave a damn; I dropped out during the first semester and went to college for 3 years instead. Decades later, I've never had a job that required any sort of chemistry, and I certainly don't feel like I've missed out on anything.

Since I can't figure out superscripting, please read B^2 as B squared ... Let A = B Multiply both sides by B: AB = B^2 Add B^2 to each side: AB + B^2 = 2B^2 Subtract 2AB from each side: B^2 - AB = 2B^2 -2AB (B^2 - AB ) = 2*(B^2 - AB) 1 = 2 QED.

Makes sense, perhaps I should have tried that ... :-O

I wish to meet all of the people who say "soil research is useless to programmers." My client just called me and told me that their indicative beet cyst nematode research does not display the eggs per larva per 100 ml correctly. Also, if I can create a report showing yearly infections of rostochiensis, pallida, or both. Meloidogyne is going pretty well though.

Years ago, in the 1980s, and in a land far, far away, New Jersey, I developed a radar display on a PC for the FAA. Those were the days of the '286 and they were s-l-o-w and floating point was an unavailable hardware option. In order to keep up and display the data in a circle, I had to re-derive the standard SIN, COS, and TAN functions to recognize 0 degrees as the positive Y-axis instead of the traditional positive X-axis. Or, to put it succinctly, how well do you understand trigonometry and integer processing?

I would never say math is useless, but when people find out I write software, a frequent reaction is, "Wow, you must be really good at math." I think I'm above average in numeracy, but I sort of maxed out at calculus, so no, I'm not really good at math, but this is a common misconception. So I explain that, while developing some types of software requires very high math skills, other skills are more universal. For example, being able to anticipate how your users will use your software is very important regardless of the type of software.

I ended up working for a bank, and they have some really weird calculation structures. Whenever anything more than basic maths was required I pointed them a the quants who live in that space. In 30+ years of building business solutions I never required any of the mentioned maths. What the bloody hell have they got you doing and why?

I wouldn't say "math is useless to programmers" - rather "math is of little significance to a large number of programmers, especially those doing line of business stuff and e-commerce. I have zero use for laplace transforms or matrices or trig. I have minimal use for even basic algebra 95% of the time. Math is a tool - like all tools, it has jobs it's fit for and jobs it's less fit for.

Surely not useless but I don't think it deserves the emphasis it has, when I needed FFTs I learnt them, I never had a need for Laplace so I don't know it, I remember some basic trigonometry and I never had a need for something remotely as "advanced" as what we did in school. School taught me to learn, what I learnt is largely irrelevant to me now. If I could go back and chose to not have some math classes, I would do it

I also had to re-derive sin, cos and tan functions to properly apply a vectorial control in real time... multiple times for different projects :D from simple "closest value in LUT" to "linear interpolation between adjacent values".

Motor control. If you want to have a brushless DC motor running you have to pilot 3 phases with adequate currents - and we can't use the standard 6 point drive because it is noisy.
