I grow weary of arguing against things which could be right, but I prepared this so might as well still post...

This is because they proved, after getting their degree, that they understand what they will "criticize".

20 years of being told sweet nothings from kindergarten maths to university graduation, is an awfully long time to remain on the fence. Also getting C- (or lower) isn't  proof of understanding.

If that were true, scientists weren't be fiercely trying to test all the current theories to the limit in this very moment.

In between all the worrying about jobs, pay, funding, prestige, career growth, peer pressure oops did I say pressure I meant review... A believable result might be more important than a novel result.

You'll be unsurprised to be reminded that I don't have much direct interest in either rigour or definitions. Aliens might discover real and then complex numbers in the same order those pesky humans did millions of years later. They might take a pass on complex numbers.  It doesn't change what it is.

The FTA has many proofs as I gather from some googling. 

See if you can invalidate one of the proofs.

That's not what I want to do or my point.

Here is a proof to get you started.

Oooh painful and long. Maths isn't really for me. (Though check out https://acdc.amherst.edu/view/octagon:144/CONTENT )

But that mathbitsnotebook Example 5 is a good example of my point about the 'supreme magnificence' of the FTA:


--- Quote ---Find the roots (zeros) of the polynomial function P(x) = x^4 - 16.
Factor. ... (x^2 - 4)(x^2 + 4) = 0
Factor again. (x - 2)(x + 2)(x^2 + 4) = 0

--- End quote ---

We make a polynomial out of factors (equivalent to saying "it was factored"). We then look for zeroes, which we just defined. We notice the 'positive' factors (eg x^2 + 4) cannot be factored further, so we define a solution. Then we get all excited that these solutions exist!

You can see that my problem is not with the x^2 + 4 = 0, but the evidence given in support being a circular argument. Similar to what penfold was saying.

Sounds like you'll never be happy.
You'll be bitterly disappointed that there is no mention of quantumelectrodynamics.

We are all eager to see Veritasium's Pt2.  And it might spur AlphaPhoenix to do his own promised Pt2 (but i doubt it)(chicken).

I have already pointed out on this here thread that Veritasium's lamp glows koz of induction tween the parallel wires, ie after a delay of  1/c seconds (ie 3.3 ns for the 3.3 ft gap).
And i have already pointed out that the primary cause of Veritasium's electricity flowing from the negative terminal of his lead acid battery (at the speed of light c) is due to my elektons (photons hugging the Cu). The elektic energy is mainly in my elektons, not in Veritasium's silly Poynting field. I have already explained that the Poynting Vector explains things, but duz nothing.

Anyhow, today i found that Bob de Hilster (a retired EE) has a youtube claiming that it his G1 particles that orbit a nucleus in a lead acid battery, & they then jump onto the lead terminal, & they then flow onto the Cu wire (at the speed of light c), his G1 particles being electrons that have lost their negative charge [see 2:40 of his youtube below].
My own theory says that my elektons are photons that were orbiting a nucleus in a lead acid battery, & they then jumped over onto the lead terminal (whilst retaining their negative charge) & they then flowed onto the Cu wire (at the speed of light c)(hence there is a similarity of sorts to his G1 particles).

Bob also says that the G1 flow gives emf, emf duznt give the G1 flow (i agree). Bob has lots of silly ideas, but he is getting warmer.
Anyhow, while waiting for Veritasium Pt2, have a look at Bob's footage.
