Are you bored, mortals? Ask A.I., "how to become immortal?"..

Spoken Into Existence
The God of programmers (and anything else) calls it recursion https://en.wikipedia.org/wiki/Recursion_(computer_science) ..programmers make code.. If ChatGPT knows all of quantum physics, then say "create a software simulation of the entire Universe".. https://www.scienceforums.net/topic/128282-chatgpt-logic

LaTeX practice
If you want to reply something that is controversial, turn off the PC/mobile and wait until you sober up or so.. This is not dependent on the members here. Older forum software allowed you to preview math equations before posting. A newer forum update screwed that up.

Mortals can't handle it.. Not really. People are suspended for days, weeks and months. For breaking the rules. Usually for being rude. Don't be rude, and you can get up to 100 negative reputation points if you want

LaTeX practice
A few years ago, I sent a MySQL programmer (i.e. Oracle dev team) a source code that contained only ~ 1000 lines of x64 machine code and told him "analyze it, find the error, this is what I will do this evening/night" (he had previously told me that he had spent a whole month writing 30 lines of C/C++ code at his previous company).. My only concern about this code was the amount of beer on the table that I had. Some people took it too literally and began to offer me to write programs for beer....

LaTeX practice
Some (lazy) users use LaTeX online editors https://www.google.com/search?q=latex+online+editor (not me) (I can even write code in x86/x64 assembler)

LaTeX practice
Looks good so far. use \frac { xxxx }{ yyyy } to get division.. e.g. [math]f(x)=\frac{1}{x^2}[/math] If you see that some other member has used LaTeX, RMB on his equation, pick up Show Math As > TeX commands, copy'n'paste and learn from it.

solid state hard drive
When the HDD has to stop, the header has to land somewhere, this is header-landing-zone. https://www.google.com/search?q=hard+drives+landing+zone When there is an accidental shutdown of the computer without properly shutting down the computer (e.g., a power failure), or when you have a hard drive in your laptop and are moving it, the head will hit some random spot on the platter and may cause damage. Modern HDDs are less prone to damage than older designs (>= 20-30 years old), which could not survive any single move without some damage. A laptop with an SSD, you can move it any way you want without worrying about damaging the platters.

Early Universe Nucleosynthesis
For clarity, write a description of all variables and their dimensions/units.

Vertical rocket landing via helium ?
You would have to have liquid helium containers and balloons that are popped from the top and filled with gaseous helium (after it's heated) for this to make any sense.

ChatGPT logic
I saw a video where the author asked ChatGPT to write a program in C++ (exercise from a university student manual). ChatGPT generated the C++ program in a few seconds line by line. Then the author said there was a bug in your code - dividing by zero was not handled correctly - without a line number there was an error. ChatGPT generated a new program with corrections. Maybe you should ask ChatGPT to write a program in C++ that uses the TCP stack to connect to the Internet? If it is not given, give material from the tutorial on how to do it. Then expand on how to connect to HTTP. Analyze the network structure to which ChatGPT is connected, etc. etc. *Sigh*.. all I see are just words.. ask about the math i.e. provide the mathematical equations.. ask for details of what the parameters mean.. and whether ChatGPT understands them.. etc.

MathML test
RMB = Right Mouse Button. LMB = Left Mouse Button. Click in studiot's first post, on the regular PC, on the chemical formula he used as an example.
-
MathML test
It is MathJax https://en.wikipedia.org/wiki/MathJax After RMB on studiot or joigus math equation, you can pick up Show Math As > Math ML Code. You start it by [ math ] tag and [ /math ] tag as the end (remove spaces). Inside you use LaTeX.

MathML test
No. What I posted was not MathML. I simulated MathML functionality using superscript button. Web forum editors usually filter HTML tags, as this is a potential security vulnerability if the user can enter any tag.

You can use only what is supported. Or make screen-shot of MathML online editor, clip to small size, and add here image in the reply.

MathML test
d3nxd3npρ(x,p) How did I do it? I copied and pasted your mathML into online MathML editor, and noticed 3n are superscript, selected them in pressed x2 button in tool box. For such simple formula as you used, it was enough without bothering about LaTeX..

Electricity
"Full battery" has charges (electrons) with a certain amount of energy.. "Empty battery" has charges (electrons) that released this energy.. Connect the plus electrode with the minus electrode and you will have fire or so.. because of the extensive release of energy in a short period of time..

Electricity
What does this change? The charge is just a property of the particles that participated in the whole action.. Q=Ne In the end, the charge is const.

Designing better spaceships ?

Designing better spaceships ?
My concerns were not primarily about space radiation shielding. I was on the subject because his structure would/could not work.. What is wrong with you today? You cannot have two objects with just vacuum inside - they would collide each other after acceleration of any of them.. ps. Have too much time on vacations from work for government? Buy a 3D printer.. The structural integrity between the outer surface and the inner surface is none, because there is a vacuum between them and nothing else.... This should be obvious to any physicist (or former physicist)..

Designing better spaceships ?
If you have a larger sphere with an inner smaller sphere and a vacuum between them, and the inner sphere will be accelerated, they won't fly together until the inner sphere hits the body of the outer sphere, so you would have to have some structure/mechanism to separate them and accelerate them together. At the moment, human use water as layer of protection against harmful cosmic rays. https://www.google.com/search?q=human+water+layer+protection+cosmic+rays "Currently, NASA and other space agencies plan on using water as a shield against radiation since it is already necessary for human missions. Water has been tested thoroughly and has been proven to be effective." https://en.wikipedia.org/wiki/Health_threat_from_cosmic_rays

Particles are Visible!
The annihilation of positrons with electrons is an important source of energy emitted by the Sun. ~ 7.8% of the all emitted by the Sun, at the moment. More than ordinary Hydrogen-1 fusion (0.42 MeV per reaction, in which part (half) of energy is took away by neutrino). https://www.scienceforums.net/topic/85656-solar-fusion-neutrinos-and-age-of-solar-system/ Electrons can be captured by the nucleus. https://en.wikipedia.org/wiki/Electron_capture Eventually, even rarer, double electron capture: https://en.wikipedia.org/wiki/Double_electron_capture Electron and positron can be transformed into electron neutrino and antineutrino. Instead of the usual annihilation into gamma photons.

Particles are Visible!
Old CRT television (century age technology) use a beam of electrons that is emitted from an electron gun toward a fluorescent screen. When the electrons hit the screen, they are decelerated and photons are emitted, which can be seen as an image on the screen. When photons hit atoms in your eye, the atoms are excited and converted into electrical impulses.
