Not sure if true, but allegedy he insisted his son not go into maths, as he would simply end up in his father's shadow as he deemed it utterly Impossible to surpass his brilliance in maths :'D
Definitely true but also bad parenting. Gauss was somewhat of a freak of nature when it came to math. Him and Euler are two of the most unreasonably productive mathematicians of all time.
Nepotism existed since time immemorial but for a mathematical genius, what was the nepotistic deliverable for the child? A sinecure placement at university?
Doubly so when the rationale is “I’m so fucking awesome”
Triply so when it’s something you’re passionate about, presumably inherently.
Quadruply so when it’s your child. Its tough as a kid hearing your parents come up with elongated excuses why you can’t dream and work towards a future.
When you let people find their own way, you might even learn something from it (ex. 70 yo Gauss learns he didn’t need to tie his mental state to his work because his son doesn’t suddenly become depressed from not matching dads output)
Re: second half, sounds about right, confused at relevancy though (is the idea the child would only do it to pursue nepotistic spoils and an additional reason is the spoils aren’t even good?)
So, a nepotistic delivery was beneficial for his family, and advising his son to seek excellence outside the shadow cast by Gauss himself wasn't stamping on dreams (in my view) it was seeking the happiest outcome.
Without overdoing it, the suicide rate for rich kids with famous parents isn't nothing. There are positive examples, Stella McCartney comes to mind. She isn't wings.
In contrast, Gauss disliked teaching and also tended to hoard those good ideas until he could go through all the details and publish them in the way he wanted. Which is a little silly, as after a while he was already widely considered the best mathematician in the world and had no need to prove anything to anyone - why not share those half-finished good ideas like Fast Fourier Transforms and let others work on them! One of the best mathematicians who ever lived, but definitely not my favorite role model for how to work.
Of course, irascible brilliance and eccentricity has an honorable place in mathematics too - I don't want to exclude anyone. (Think Grigori Perelman and any number of other examples!)
They, Newton included, would often feel that their work was not good enough, that it was not completed and perfected yet and therefore would be ammunition for conflict and ridicule.
Gauss did not publicize his work on complex numbers because he thought he would attacked for it. To us that may seem weird, but there is no dearth of examples of people who were attacked for their mostly correct ideas.
Deadly or life changing attacks notwithstanding, I can certainly sympathize. There's not in figuring things out, but the process of communicating that can be full of tediousness and drama that one maybe tempted to do without.
As if phd students need more imposter syndrom to deal with. Ona serious side, I wonder what conditions allow such minds to grow. I guess a big part is genetics, but I am curious if the "epi" is relevant and how much.
There's a spread of farmers, railroad and telegraph directors, high level practical infomation management skills in the children.
In my view the Fourier Transform is still useful in the real world. For example you can use it to analytically derive the spectrum of a given window.
But I think the parent is hinting at wavelet basis.

Not the first time I've heard this on HN. I remember a user commenting once that it was one of the few perspective shifts in his life that completely turned things upside down professionally.
As to the listed patent, it moves uncomfortably close to being a patent on mathematics, which isn't permitted. But I wouldn't be surprised to see many outstanding patents that have this hidden property.
* not a legal definition, IANAL.
On a more mundane note: my wife and I always argue whose method of loading the dishwasher is better: she goes slow and meticulously while I do it fast. It occurred to me we were optimizing for frequency and time domains, respectively, ie I was minimizing time so spent while she was minimizing number of washes :-)
I'm probably just slow, but I'm not following. Do you mean because you went fast, you had to run another cycle to clean everything properly?
If you haven't already, you should watch the Technology Connections series on dishwashers.
That lower bound is the uncertainty principle, and that lower bound is hit by normal distributions.
Of course some differences exist (e.g. basis vectors are fixed in FFT, unlike PCA).
I guess if you want to use different modulations you treat the complex number corresponding to the subcarrier as an IQ point in quadrature. So you take the same symbols, but read them off in the frequency domain instead of the time domain.
And I guess this works out quite equivalently to normally modulating these symbols at properly offset frequencies (just by the superposition principle)
After all, what Copernicus showed is that the mind bogglingly complicated motion of planets become a whole lot simpler if you change the coordinate system.
Ptolemaic model of epicycles were an adhoc form of Fourier analysis - decomposing periodic motions over circles over circles.
Back to frequencies, there is nothing obviously frequency like in real space Laplace transforms. The real insight is that differentiation and integration operations become simple if the coordinates used are exponential functions because exponential functions remain (scaled) exponential when passed through such operations.
For digital signals what helps is Walsh-Hadamard basis. They are not like frequencies, they are not at all like the square wave analogue of sinusoidal waves. People call them sequency space as a well justified pun.
My suspicion is that we are in Ptolemaic state as far as GPT like models are concerned. We will eventually understand them better once we figure out what's the better coordinate system to think about their dynamics in.

> The unreasonable effectiveness of The Unreasonable Effectiveness title?
kingkongjaffa•17h ago
FTs are actually very reasonable, in the sense that they are a easy to reason about conceptually and in practice.
There's another title referenced in that link which is equally asinine: "Eugene Wigner's original discussion, "The Unreasonable Effectiveness of Mathematics in the Natural Sciences". "
Like, wtf?
Mathematics is the language of science, science would not compound or be explainable, communicable, or model-able in code without mathematics.
It's actually both plainly obvious for mathematics then to be extremely effective (which it is) and also be evidently reasonable as to why, ergo it is not unreasonably effective.
Also the slides are just FTs 101 the same material as in any basic course.

ok but it's not the FTs that are unreasonable, it's the effectiveness
I think we all understand at this point that "unreasonable effectiveness" just means "surprisingly useful in ways we might not have immediately considered"

It's not easy to separate cause and effect from direct and strong correlations that we experience.
The job of a scientist is not to give up on a hunch with a flippant "correlation is not causation" but pursue such hunches to prove it this way or that (that is, prove it or disprove it). It's human to lean a certain way about what could be true.
Certhas•16h ago
If that is what you are saying I suggest that you actually go back and read it. Or at least the Wiki article:
https://en.wikipedia.org/wiki/The_Unreasonable_Effectiveness...
By means of contrast: I think it's clear that mathematics is, for example, not unreasonably effective in psychology. It's necessary and useful and effective at doing what it does, but not surprisingly so. Yet in the natural sciences it often has been. This is not a statement about mathematics but about the world.
(As Wittgenstein put it some decades earlier: "So too the fact that it can be described by Newtonian mechanics asserts nothing about the world; but this asserts something, namely, that it can be described in that particular way in which as a matter of fact it is described. The fact, too, that it can be described more simply by one system of mechanics than by another says something about the world.")
kingkongjaffa•16h ago
> Wigner's first example is the law of gravitation formulated by Isaac Newton. Originally used to model freely falling bodies on the surface of the Earth, this law was extended based on what Wigner terms "very scanty observations"[3] to describe the motion of the planets, where it "has proved accurate beyond all reasonable expectations."
So despite 'very scant observations' they yielded a very effective model. Okay fine. But deciding they should be 'unreasonably' so is just a pithy turn of phrase.
That mathematics can model science so well, is reductive and reduces to the core philosophy of mathematics question of whether it is invented or discovered. https://royalinstitutephilosophy.org/article/mathematics-dis...
Something can be effective, and can be unreasonably so if it's somehow unexpected, but I basically disagree that FTs or mathematics in general are unreasonably so since we have so much prior information to expect that these techniques actually are effective, almost obviously so.
Certhas•4h ago
And no, this is unrelated to whether math is invented or discovered. If anything this is related to the extreme success of reductionism in physics.
As a general point of reflection: If an influential article by a smart person seems silly to you, it's good practice to entertain the question if you missed something, and to ask what others are seeing in it that you're missing.

So, biology and medicine are not sciences? Or are only sciences to the extent they can be mathematically described?
The scientific method and models are much more than math. Equating the reality with the math has let to myriad misconceptions, like vanishing cats.
And silly is good for a title -- descriptive and enticing -- to serve the purpose of eliciting the attention without which the content would be pointless.
hogehoge51•15h ago
Which means, the language of some fields can’t be math.
However, I don’t think the original presenter was asserting those fields aren’t science, that’s an unreasonable interpretation. More so , ideally they would be use math as it is a language that would help prevent the silly argument “so, Y is not X?, or is Y only X provided Y is in the subset of X that excludes Z? “
(Even in Engineering, we hit this cognitive limit, and all sorts of silliness emerges about why things are or are not formalised)
cubefox•17h ago
I agree this is getting old after 75 years. Not least because it seems slightly manipulative to disguise a declarative claim ("The Fourier transform is unreasonably effective."), which could be false, as a noun phrase ("The unreasonable effectiveness of the Fourier transform"), which doesn't look like a thing that can be wrong.
