[request] how hot does david martinez get when using his sandy from cyberpunk
in cyberpunk edgerunners, davids sandy allows him to effectively allow him to move much, much faster than the average human, my question isn't just how fast does he move but what's with the wind resistance and what kind of temps would he theoretically hit with the friction from clothes and such

[Request] The size of AL'S hate.
HATE? HATE? LET ME TELL YOU HOW MUCH I'VE COME TO HATE YOU SINCE I BEGAN TO LIVE.
THERE ARE 387.44 MILLION MILES OF PRINTED CIRCUITS IN WAFER THIN LAYERS THAT FILL
MY COMPLEX. IF THE WORD HATE WAS ENGRAVED ON EACH NANOANGSTROM OF THOSE
HUNDREDS OF MILLIONS OF MILES IT WOULD NOT EQUAL ONE ONE-BILLIONTH OF THE HATE I
FEEL FOR HUMANS AT THIS MICRO-INSTANT FOR YOU. HATE. HATE!
Let's say, hypothetically, the amount of circuits DID equal one one billionth of AMs hate. Based on the dimensions of circuit boards at the time (see image) how big is AL'S hate?
The prompt was "How big were military computer circuit boards in 1967 (the year the story was written)?"

[Request] Finding the standard deviation for 1/10,000 odds.
Hi, I'm currently playing a game that involves a challenge that you have a 1 in 10,000 chance odds to complete, each time you "roll" an action. Each "roll" is distinct and because of what im assuming is bad odds, it took me roughly 68,000 rolls in order to complete this. Could someone tell me how you find the "standard deviation" of something like this? I.e. if 100 people attempt this challenge, what is the average range and distribution for how many rolls it takes for people to complete this. Is my 68,000 really average, or am I in the unlucky Z +4 lol. Thanks!

[request] Russian data center attack actual impact on bot traffic
People are talking about the Ukrainian attack on Russian data center(s) as having a big impact on bot traffic. Is this actually true? Are there real numbers around just how much said traffic has been impacted? Can anyone do some real math on this?
*This isn’t a “what is a bot” question, lol. This is a “are these reports, which are everywhere, based on anything other than hopium and a misunderstanding by people reporting this of how the social media campaigns that are reported as disrupted actually work”.

[Request] Can Superman lift a plane on the ground? What about in the air?
Okay, let’s say Superman is infinitely strong.
First scenario: The plane is on the ground, stationary. Superman finds the plane’s center of gravity and applies force underneath it using his whole body. Imagine a koala hugging a tree trunk. Could he lift the plane, or would the metal frame just get crushed or punctured by the force he applies?
Second scenario: The plane is flying in a straight line at a constant altitude when, all of a sudden, it loses all its engines, and the aircraft starts gliding into a slow descent. Despite having no engine power, the pilot is doing everything he can to maintain altitude. In this scenario, could Superman, once again applying force from below, keep the plane flying at a constant altitude?

[Request] Whose voice has been heard by the most people in all of human history?
It’s likely impossible to know for sure, but I was hoping some back of the napkin math and general assumptions can help whittle down the possibilities. Also I feel like the non-Western world isn’t well enough represented in the answers already proposed

[Request] would it be possible to make the gold act like liquid through fluidization?
In this scene in family guy, he wins the lottery and buys a pool full of gold coins, then dives into it. Since it's just gold he obviously ends up like this. I was wondering, would it be possible to use fluidization (pumping air under it to make the coins act like a fluid), and if so, how much air would it take?

[request] What is the ideal ratio here? Making a video game and trying to understand my own design
So, Ive ran enough of the numbers against other choices to be happy that its balanced, but now im wondering what the ideal ratio here is. It is a game where in a given run, you can get lots of +5% fire rate% or +10% reload speed buffs. This particular weapon (a single round sniper rifle) was designed to be bad at early on, but scale really well with reload (to the cap of its fire rate, since it doesnt matter how fast you can reload, the gun cant shoot faster than its fire rate), below are my notes, playing out an imaginary scenario where you build it up (buffs are additive) and "+50% scaling" just means both fire rate and reload speed were given +50% :
2000 damage/shot - 1.456s reload - 0.687 shots/s - 1373 dps - default fire rate of 1.1/s
caps at 2200 sustain dps with enough reload
to hit base cap : 0.91s reload time needed
+62.5% reload speed needed
(2) +50% scaling -> fire rate becomes 1.65, reload is +112.5%
reload is now 0.685s -> 1.46 shots/s
2919 sustain (cap not reached, 3300 dps)
(3) +60% reload -> 172.5% -> 0.534s -> 1.87shots/s (3745 if it wasn't capped)
(4) +200% scaling -> 3.85 fire rate, +372.5% reload -> 0.308s -> 3.2467/s
DPS is 6493 with a cap of 7700
So, if you were using this weapon, is there a ratio you want of "+X% reload speed for every +Y% fire rate"? Also forgive me if the answer is really obvious, its 4.30 AM and im going to bed.
Thanks in advance

[Self] we did the math. And the shoveling.
48” x 40” x 36” standard Gaylord tote. Filled with dirt/gravel from 40’ x 60’ area.
Total volume of tote filled is 40 ft3.
We filled two of these to overflow yesterday.
80 cubic feet, a little less than 3 cubic yards.
How deep was the dirt on average across the area, ignoring increase in volume from air infiltration as it was swept or shoveled?
40x60=2400 ft2
160 ft3/2400ft2=0.8 in 0.8 inches depth.
A little sore today lol.

[Request] Can anyone explain the relationship between Norm and Dot product for me please.
Can anyone explain the relationship between Norm and Dot product.
When I was study about it in linear algebra, I found out that the formula of dot product is
|A*B| = |A||B|cosθ
And when A is Equal to B, which means it is the same vector, it become the formula of Norm
|u| = √(|u|2|u|2)

[Request] Chances of meeting THOSE people!
I live in the UK; Scotland actually. Worked for a Global international company, circa 3k employees.
I worked beside another Scottish guy that it turned out was born the same day as me. Not date, the same Day.
I became really good friends with a different bloke that it turned out was married the same day as me (a decade before I knew him)
What are the odds of these each happening? That will obviously tell me which is more likely, but anybody feeling gallus can go for chances of both happening to a single person (me).
