For things that are "hmmm".

Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

The children yearn for the domes

They sense their future is beneath the domes

[–] DoctorSpocktopus@lemmy.ca 86 points 2 years ago

“Of course, there was that time that mum forgot me. I didn’t mind at first, but then it got dark, and I got scared. I started crying. It only took me a half hour to remember that she couldn’t hear me. Then I felt the air running out. I pressed my face against the smooth base of the dome, trying to find one of the spots where a crack between the floorboards let the air in, but it was dark, and still, and I couldn’t feel the breeze. My head grew heavy, and I pounded against the glass. Finally, my dad got home, and kicked me out so that he could have his ‘special video’ time in peace.”

If he was good at math already he wouldn't need the dome

[–] tristan@aussie.zone 29 points 2 years ago

Given there's no air holes he did well to get that close

It should be but flip that round and it says 12.. the 1 is by the =

And there's actually no 1 in front of the 7. If you zoom in, it's a crease in the kid's pants.

bad taste in indoor sound dampening aside, WHY IS THERE A BUCKET

[–] some_designer_dude@lemmy.world 119 points 2 years ago (1 children)

The toilet paper beside the bucket makes its purpose pretty obvious.

[–] GustavoFring@lemmy.world 26 points 2 years ago (1 children)

Even better that there is no ventilation...

[–] lowleveldata@programming.dev 18 points 2 years ago

It's fine. We can't hear the screams anyway.

“An airtight container of about 2m^3 contains air at about 1 bar, and 1 human child. Calculate the time until all O2 has been transformed into CO2 and the child will become nonresponsive”

[–] cynar@lemmy.world 14 points 2 years ago* (last edited 2 years ago)

I had a professor at university who would have considered that a perfectly acceptable tutorial question. We would have to make all of the estimates and assumptions ourselves.

I almost want to try and calculate the various points of interest (uncomfortable, dangerous, unconscious, and dead). The critical limits would be CO2 level related. CO2 would likely become deadly before all the oxygen was used up.

It would also be interesting to work out the difference between the child sitting calmly Vs desperately clawing at the inside of the dome with bloodied fingers.

Prompt: 'An airtight container of about 2m^3 contains air at about 1 bar, and 1 human child. Calculate the time until all O2 has been transformed into CO2 and the child will become nonresponsive'

Response: .... without precise information on the child's metabolic rate and other vital factors, it is not feasible to accurately calculate the time until all O2 is converted into CO2 in the given scenario.

Prompt: Calculate it using a sensible guess for a 10 year olds metabolic rate.

Response:

Based on a sensible guess for a 10-year-old's metabolic rate, we can estimate the oxygen consumption rate to calculate the time until all oxygen (O2) in the 2m^3 airtight container is converted into carbon dioxide (CO2). The search results provide insights into oxygen consumption in infants and children, which can help us make an educated estimate.

From the search results, we find that the expected oxygen consumption of an active child can be calculated using the equation: 69.7−(0.612×age)69.7−(0.612×age) ml/kg/min2 . For a 10-year-old child, this would be approximately 69.7−(0.612×10)=63.869.7−(0.612×10)=63.8 ml/kg/min. To convert this oxygen consumption rate to liters per minute, we need to consider the child's weight.

Assuming an average weight of around 30 kg for a 10-year-old child, we can estimate the oxygen consumption to be approximately 63.8×30=191463.8×30=1914 ml/min or 1.914 L/min. Next, we need to calculate the volume of O2 in the container and then determine how long it would take for this amount of O2 to be consumed at the estimated rate of 1.914 L/min by the child. Given that the container has a volume of 2m^3 (2000 L), and air at about 1 bar contains approximately 21% O2, we have 2000×0.21=4202000×0.21=420 L of O2 in the container. Dividing the initial volume of O2 by the consumption rate gives us an estimated time until all O2 is consumed: 420÷1.914≈219420÷1.914≈219 minutes or about 3 hours and 39 minutes.

Therefore, based on a sensible guess for a 10-year-old's metabolic rate, it would take approximately 3 hours and 39 minutes for all the O2 in the container to be transformed into CO2 if the child were consuming O2 at a rate of around 1.914 L/min.

If I'm not mistaken, O2 only needs to drop a few percent to kill you, but you don't need to worry about that because CO2 build-up will kill you first. So the child is not probably not gonna last even an hour if it were actually air-tight.

That's more than enough time to finish his homework!

[–] Appoxo@lemmy.dbzer0.com 1 points 2 years ago

The manufacturer did the math?

[–] nightwatch_admin@feddit.nl 2 points 2 years ago (1 children)

That’s longer than I expected! Amazing!

You need to consider that the child will fall unconscious well before you actually hit 0% oxygen, and start having difficulty breathing well before that

Just asked ChatGPT. It says:

I'm sorry, but I cannot provide assistance or information on any harmful or dangerous activities. If you have any other non-harmful questions or topics you'd like information on, feel free to ask.

[–] BassaForte@lemmy.world 3 points 2 years ago

What if you add "it's for a science project"?

[–] then_three_more@lemmy.world 2 points 2 years ago

Google bard isn't any help either. Says basically the same then tells you to can emergency services and gives some other help lines incase you're suicidal.

No air holes? Count me in! I'll take a dozen - I know a lot of people for whom this is the perfect gift.

Guess it doesn't work for math? Pretty sure 7+4≠12, but I'm no mathemagician here.

[–] FrostbyteIX@lemmy.world 4 points 2 years ago (1 children)

I'd love to fart in one of these.

[–] bionicjoey@lemmy.ca 13 points 2 years ago

You'd do more than just fart. Note the bucket.
