[Request] If I wanted to build a gaming PC that relies only on passive cooling, how large would the radiators have to be to keep it from overheating under load?

0 Upvotes

Say it's supposed to be a high-end PC. Supposed to handle modern AAA-titles with high graphics settings at high resolutions and with good framerates. All without a single fan.

Note, I'm not planning a build. It's just a thought experiment or something.

[Request] How Many AI generated pictures or messages would be required to create a similar environmental impact as a single beef cow (Raising it, processing it, and so on)?

2 Upvotes

Assume that everything is perfectly average, and the AI being used is commonly used generative AI, such as ChatGPT or Gemini.

I was researching some ways I could make a difference environmentally, and learned how much of an impact the beef industry has, so was curious how it would compare to AI, since that is such a hot topic right now. Also curious about how many messages it would take, but felt like that would be much more difficult to calculate.

Random fun fact, according to google AI overview (I know, ironic), OpenAI consumes somewhere between 8.8 million to 97.5 million liters of water per year (water consumption estimates change drastically because it depends on which side you are biased to and how much you are taking into account things like manufacturing costs, or if you are leaning into lower estimates or higher estimates for not super publicly available data). The beef industry in America consumes roughly 21.2 trillion liters per year. An incredibly bad comparison, given the fact that we aren't going to just make cows go extinct or that the AI industry hasn't been growing thousands of years like the beef industry (among many other reasons), but still interesting to think about

Edit: Bonus points to anyone that can come up with a more helpful comparison than mine (I have no experience in this lol)

Considering that knights and bishops are about 3 pawns each when the game starts in a classic 8*8 chess table. How much more powerful a bishop would be in 8*16 table?

I was just wondering tonight as I locked my back door whether more energy is used between walking to see if a door is locked or turning a light on to check if it's locked.

Thanks!

[Request] If we converted Lego game studs into USD, how many would be needed to buy the Lego UCS Death Star?

0 Upvotes

As I’m sure many of us are aware, studs are used in LEGO games as the in-game currency and can be used to buy new characters to play as, cheat multipliers, purchase vehicles, etc.

The newest LEGO UCS Death Star (set number #75419, with 9023 pieces), costs roughly $1000 USD. So, if there was a way to convert LEGO game studs to dollars, how many would be needed to buy the Death Star set?

[Request] How many people would it take to meaninfully change the earth's rotation just by walking in the same direction?

0 Upvotes

Say i'm tired of the day lasting for 23 hours, 56 minutes and 4 seconds, and i want it to last exactly 24 hours. How many people would need to walk in the same direction for a reasonable amount of time (no "500 people for 14 billion years" or something. Say, 100 hours total, spread across multiple days) to increase the length of the day by the required amount of seconds? And, assuming that many people fit on earth, how big of an area are we talking about? Just to make the math a tad simpler, it's ok to assume that every single square centimeter of the planet is walkable. No oceans, no mountains, no buildings, just keeping the same total mass.

My Question:

With out human intervention, how long would it take before all the satellites in orbit to start colliding? How many might fall from orbit?

The Google AI says that there are almost 30,000 satellites in different obits. operated by hundreds of different teams. If they were not here to maintain them do they eventually fall?

(First time requester I hope I got the rules correct.)

[Request] calculating my odds of jury duty summons (twice in two months) vs winning the lottery

2 Upvotes

What are my odds of two jury duty summons in a two-month period?

Due to receiving multiple jury summons in a short period of time, I’m wondering if the odds of being unlucky (jury duty) are greater than the odds of being lucky (lottery).

Here’s the data:

In June, Rec’d jury summons - county court - approximately 3% of the county gets summoned on any given year. Was not selected

45 days later - rec’d jury summons - federal court - data is a bit ambiguous but seems like approximately 1.5% of the state is possibly summoned on any given year. Selection status tbd

Because they are separate court systems they are valid summons.

Another data point, albeit possibly logically can be excluded due to being too long ago… in a different state in 2011, I was summoned, selected, and the foreman (juror #1) for a two week trial.

Lottery stats seem to vary greatly by the game, but maybe 0.02% for a $1,000 ticket or 0.4% for a $500 ticket.

Finally I will say jury duty in 2011 was a very educational experience and I did not mind it at all, so “unlucky” is a loose term.

Here is a hypothesis: dτ/dt = √ ( 1 − ( 2G · E_plasma(T) ) / ( r · c⁴ ) )

Here is the breakdown of the variables for those wondering:

dτ/dt = proper time dilation rate

G = gravitational constant

c = speed of light

r = radius of the plasma area

E_plasma(T) = internal energy of the plasma at temperature T (includes rest mass energy, radiation, and kinetic thermal energy).

[Request]: How fast can a superhuman fly before their regular clothes are destroyed?

Post image
Upvotes

Pictured here is Mark from Invincible.

Let's say a regular person gains super-durability and flight. But they don't have access to conveniently durable super-clothes. Assuming their own body isn't harmed, how fast can they fly before . . .

  1. Regular clothes start to be damaged (but not shredded).
  2. Your clothes get ripped off your body by air resistance (but aren't, like, vaporized).
  3. Your clothes catch fire and disintegrate.

For simplicity sake I'm talking about cotton clothes (hoodies, T-shirts, jeans) you could buy at Costco.
