How is this allowed in America?

Literally a black crack selling gun toting gangbanger bastard son of a single mother is somehow admitted to a university, accepted into a PhD program, appointed a prestigious teaching post and accepted into mainstream academia

How would you feel as a colleague of this guy...at the same salary grade?

How in the fuck can you admit to selling crack cocaine to children and shooting people yet hold a federally funded position of authority and trust over teenagers/young adults?

I am a patent attorney, everything I work on is secret until published, 18 months after first filing. If the military finds the invention interesting, they can essentially take control, and the case is pretty much out of the hands of the applicant/inventor.

This happens, and has a name: Zeitgeist. It has been known to happen since the dawn of civilisation. The Leibniz/Newton dispute over calculus is well known but it also happens in our age. It also happened to a client of mine.

It is said that the speed of light is the same in all reference frames. It is also said that light travelling around a massive object opposite its direction of rotation will be slower. Are these laws not in conflict? Which one is wrong? Is the "slower" light still moving at the same speed, but taking a less efficient path?

As a second question, does light travelling IN the direction of a rotating massive object (appear to) exceed the speed of light (from one or all reference frames)?
>>13487942
It's literally true. Light travelling in the opposite direction of a rotating black hole is slower. This should not happen, as the speed of light is constant in all reference frames, as I am sure you are aware.

>>13487947
if a massive object is rotating, then the geodesic lines of spacetime, which light travels in, are distorted as the object rotates, therefore it is possible for light to travel at the same speed, but travel a longer or shorter distance as these lines curve

I would say it would also be slower no matter the direction of light because of this reasoning

>"slower".
It's simply taking a longer spacetime path to get from A to B. But the speed at which it's traveling the path is the same. To us, which are sitting in a non-distorted region of spacetime, you could say it "seems" slower. It's more of a misuse of language.

A professor once told me that real numbers cannot be added. How can this possibly be the case? Do I not add real numbers together all the time? What strange beasts lurk in his functions, what manner of definitions is he playing with, to convince him that the reals cannot be worked with? Was he joking, or referencing some obscure work by one of his rivals? Please, educate me on this.

/shrug. Physical or metaphysical, theories that are built of first order logic should at least attempt to be internally consistent. How far do you mentally fractal zoom on the line you represent with the sqrt(2) before you give up and pretend you got there?

In addition the Wiki states
>In addition to measuring distance, real numbers can be used to measure quantities such as time, mass, energy, velocity, and many more

How quickly do our imprecise definitions make for shaky foundations in our physics.

The Babylonions, with their obsession with exact numerals (you get less '...' numbers in base 60 btw) highlights that we have something to learn from reexamining the foundations of our thought.

Doesn't it make sense too? we are about 30 years into the internet age. The Descartes, Euclids, Ramanujans got perhaps a handful of books, now we get the best of 1000's of thinkers at our finger tips, I say we dare to think we can build a better foundation, so that we can build higher the areas we have been stuck in for the past 40 or 50 years

For me its that were given real numbers to algebra with, but are than red pilled into floating point land when we try to do it in JS or Python, and why I'm learning maths from wildberger. Cant even do 1.2 - 1.1 precisely on an adding machine

Idk. I'm part of the review process and thought this shit was retarded. Came down to one person saying "I want Elon's dick" not really but mostly, I'm drunk. But anyway, yeah, the whole time I thought it would go to Dynetics with their better overall approach and not a lame ass giant fucking dildo landing on the moon to impregnate it. As usual, money, not science, wins the day.
