New Zealand Smoking Law
Politicians often create silly laws to pretend that they (politicians) are needed for anything other than screwing you over by collecting salaries.. How is this even supposed to work? In 2030..2040...2050, an adult goes to a store and the clerk asks for an ID card to see if the year of birth is < 2008 or >= 2008.. ? https://www.google.com/search?q=new+zealand+smoking+population "The drop of New Zealand's overall smoking rate to 8% would place it among some of the world's lowest prevalences." "New Zealand/Population 5.123 million (2021)" * 8% = 410k

Please name some practical solutions to combat littering.
People bother about their own property - they would not allow littering on their own property - but if somebody does it on a 3rd party - whatever..

The things that intrigue me most about the human body.
True. Cells have a lot of ancient, useless junk in their DNA to these days.. ps. You have no idea how hard it is to erase a whiteboard I have not erased for 20 years..

The things that intrigue me most about the human body.
Isn't that too easy to grasp? There are even self-modifying computer programs.. https://en.wikipedia.org/wiki/Self-modifying_code ps. Now you sound like a humanist.. "the cell wants this or that" (i.e. giving the cell a human mind, perception and the ability to consciously do something).... In what language?

Please name some practical solutions to combat littering.
PET plastic bottles can be converted into filament for a 3D printer. i.e. from "trash" you can make something valuable, which can be used to produce anything you need at house, or which you can sell and/or give away.. Littering is the result of having to pay to take trash out of the trashcan.. (and not enough trashcans everywhere, or not enough taken away regularly) Conclusions? If it is for free, then (at least ordinary) people will not litter in the woods, etc. places.. A few years ago, I came up with the idea of making automatic trash garbage cans (small, the one used in forest parks) that have wheels and detect how much trash they have inside. When they are full, they start moving to the garbage truck. Empty automatic trash cans come out from the garbage truck and replace them. They should have solar panels on them to have power. So you want China's route everywhere.. From drones and satellites too? Because people have to pay for it..

LaTeX practice
@Lorentz Jr ...or you can press (also several times) ctrl+ on your keyboard to change the zoom level of your web browser (ctrl- to reverse, or click on the percentage in the title to reset it back to 100%).. I like it. I reviewed your TeX commands - you don't need {} in some places i.e. a_{0} can be a_0, c^{2} can be c^2 etc. Basically {} tells that there is a bigger sequence.

Fusion energy breakthrough...
The essential key to performing effective fusion is ultra perfect mirrors that will reflect as much light as possible from them toward to the center.

@Lorentz Jr You can do it better - use nested frac commands..

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

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....

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.

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.

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.
