Is there any demand out there for an astrophysics textbook? I'm 6 months into working on writing one and I just realized that I never looked into it, and that there may be no demand for it at all.

Pic is sorta related. Not my textbook, but an astrophysics textbook.

I'm still in highschool but I know alot on the topic. I watched Sagan and Tysson and Kaku. I've written 12 pages for my book so far

OP:

there is no demand for a book from a child who doesn't even have a PhD yet

sorry

>> No.5076411

There's lots of demand. I hear about lots of high school students who want to get to an extremely high level, but there's no book that builds the basics. They're too lazy to get multiple books and create a curriculum themselves, so they just give up.

So you do have a PhD in astrophysics?

I would be interested OP, except I will probably pirate it. The only reason I'd buy it is if it's the most awesome astrophysics textbook ever and no one has uploaded it on the internets

Could you please answer a question on relativistic astrothermodynamics?
It's about the hypothetical collision of celestial objects of very different temperatures.

>> No.5076490

As long as plasma physics isn't an integral part of it, astrophysics is more like fairy-tale science.

Consider two celestial bodies. For the sake of simplicity lets call them suns. One of these suns has a temperature of +9001 Kelvin (the temperature of lava), the other has a temperature of -9001 Kelvin (the temperature of ice). Both are moving at 0.999... c. What would happen, if they collided?

-9001 K is a theoretical temperature. From what we can observe, it doesn't exist. This is just a wild hypothetical I assume?

Lol that's a typo. I meant absolute zero. Besides, there is nothing lower than 0 K...

This needs to be a practice problem in a physics textbook. In the answers section in the back there would just be a trollface.

Do you not understand how Kelvin temperatures work and what they represent?

>> No.5076547

>>5076544

I think you should check the article I mentioned or the nasa site posted already. Perhaps you don't understand?

>> No.5076596

>>5076547
Negative absolute temperatures are hotter than positive ones, and they'll eventually change to positive ones regardless of their surroundings. Plus, they only pertain to very specific systems. They're theoretical, and incredibly implausible at that. Gravitons have a better chance of turning out real.

>> No.5076604

>>5076596

Wrong. It has already been physically observed. It is not "theoretical" or "implausible"

>At negative spin temperatures, ferromagnetic order has been found in silver. In this metal, the phase transitions occur at 560 pK and at -1.9 nK, respectively. In rhodium, 280 pK and -750 pK have been reached; these are the current world records of low temperatures.

>> No.5076616

>>5076604
Absolute Zero has never been reached and is only theoretical. We haven't gone lower than it without having reached it.

You are silly.

It was already proven.

Also, of course something can exist and not reach zero. Picture related. -1/x function. (consider x as temperature, if you please)

OP have you tried to strike a deal with any professors? Email all the appropriate instructors, and offer them a commission for requiring the book.

Many professors supplement their income by writing un-needed textbooks and requiring each student to purchase a new copy. You simply eliminate the need to write all those books.

If you succeed, you could write more textbooks in other fields.
