If the wild allegations in the smearjob was hers, she does not rank very high on credibility. Going by what people say, it was not unusual at all to use false allegations of abuse (or adultery) in divorce proceedings at that time. Sometimes

Seems she isn't interested in dragging a bit of fame and recognition her way. It's a low effort way to do that when the other party cannot defend himself.

Very funny. You will probably be misunderstood though.

I would say read up a little so that you are in a position to make up your own mind. Also compare the video recordings and published book to figure out whose material it was. It's easy to throw muck at someone who is not around to defe

The stuff that the material in Feynman's book is not his is just made up nonsense. They follow his course lectures very very closely. The minutiae of writing may not be his, but the material certainly was his. Regarding domestic abuse

Note that this was before the times of no fault divorce. At that time it was common to allege extreme behavior (often mutually agreed upon), to Trump up the charges just to make the divorce go through.

Teller would misspell Fermi and Fuchs' names ? That would be strange.

His wife allegedly secretly reported him to the FBI as a potential spy, communist, security risk, fraud. It was an anonymous letter. Given how different this wife's (second wife) description of Feynman compared to others is, that there

To reconstruct the image one has to cut off those frequencies in the corrupted image where the signal to noise is poor. In many original images, the signal in high frequencies are sacrificable, so get rid of those and then invert. https:&#

Not necessarily. If, however, one just blindly uses the (generalized)inverse of the point-spread function, then you are absolutely correct for the common point-spread functions that we encounter in practice (usually very poorly conditioned)

Encode the image as a boundary condition of a laminar flow and you can recover the original image from an observation. If, however, you observe after turbulence has set in, then some of the information has been lost, it's in the entrop

It seems obvious now only because of significant mathematical discoveries of prominent mathematicians. If one is taught what those discoveries revealed then of course they would seem obvious. Arguing as you are, it would appear one can ca

Yes but it was a fundamental mathematical achievement to see this equivalence. That knowledge had to emerge, be discovered. This eventually led to the theory of Galois fields. The connection with rotation emerged naturally from a line of t

If you need to support zoom, scaling shows up very frequently. I can give an example from real life. A piece of code one of my colleagues was working on required finding a point on the angular bisector. The code became a tangle of trigonom

There's a significant advantage in using a tuple over a scalar to represent angles. For many operations you can get rid of calls to trigonometric functions, or reduce the number of calls necessary. These calls may not be supported by s

It entirely depends on what we mean for something to be a number. Humans over the passage of time have been recognizing that their earlier conception had been too restrictive, narrow minded. As one broadens the idea of what it means for an

Vector space over which field ? The reals ? In that case you have got a chicken and egg problem.

> I just don't like this characterization That's ok. It's a personal value judgement. However, the fact remains that rotations can "emerge" just from the desire to do additions and multiplications on tuples to be

Yes it's simple and I agree with almost everything except that arctan bit (it loses information, but that's aside story). But all that you said is not about the point that I was trying to convey. What I showed was you if you defin

When it doesn't, we yearn for something that will fill the void so that it does. It's like that note you yearn for in a musical piece that the composer seems to avoid. One yearns for a resolution of the tension. Complex numbers of

We as humans had a similar argument regarding 0. The thought was that zero is not a number, just a notational trick to denote that nothing is there (in the place value system of the Mesopotamians) But then in India we discovered that it can

Maybe. You disagreed with the parent comment that said "Rotations fell out of the structure of complex numbers. They weren't placed there on purpose. If you want to rotate things there are usually better ways." I see Complex

Twisted ? Rotated ?

by srean 9mo ago
Nope. (Just to imitate your style) There's more to it than rotation by 180 degrees. More pedagogically ... Define a tuple (a,b) and define addition as pointwise addition. (a, b) + (c, d) = (a+c, b+d). Apples to apples, oranges to orang
