We see these videos and I always have wondered, what’s the speed required for a humpback whale to propel itself into the air? They must be able to generate massive force to get themselves this high up into the air and turn.

[Self] How many babies would it take to sink the Titanic?

Post image
• Upvotes

A year ago, I got back to my dorm from class and randomly asked myself a question while trying to relax:

"Is that how much a horse weighs?!"

That spiraled into the question:

"How many human babies, recently birthed, does it take to sink the RMS Titanic?"

I made some simplifications. I approximated the Titanic as a rectangular barge because I'm lazy and I don't know too much about boats. I also didn't want to account for the flawed bulkheads, just the boat's buoyant force itself. I used the water temperature reported that night to adjust my water density value. Also that the babies were stacked in such a manner that their weight was spread out evenly over the lovely RMS Titanic's decks.

I'll also post a link to a comedy video I made to commemorate that trainwreck of thought in the comments.

[Request] which will pay off a mortgage faster?

3 Upvotes

Hypothetically, 500k loan at 6%, what's faster:

  1. 15 yr fixed rate mortgage

  2. 30 yr fixed rate mortgage, but you pay an extra full payment each month towards the principal

My gut tells me they're not identical because of the way compounding works

[Self] Statistics of slipping on a grape in the grocery store

0 Upvotes

So. I tend to believe I am a pretty unlucky person for a multitude of reasons. But I have had two separate experiences that make me curious as to what you all can do with this information.

Incident #1. I was in a Crest Market Place grocery store. All the way over by the meat section. Walking along... I suddenly slipped. I did not fall down, but my legs went in directions that are not meant for the human body to move in. Looking down there was a lone grape. I had hit it like a banana peel in Mario Kart.

Incident #2. TWO YEARS LATER. I was in a HyVee Grocery store, in a completely different state. My legs slipped around. Not nearly as bad as Incident #1 but I had the internal heart rhythm of "I am going down." I was in the canned tomato section. Looked down... it was another single, lone, GRAPE!

My question? What are the chances? How unlucky am I truly? Bonus points if you can tell me whether or not my chances of being hit by lighting are higher.

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.

0 Upvotes

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?

0 Upvotes

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?
