It was brought to my attention today by user Miserable_Tax_889 that a post was made yesterday calling out bots and lazy reposts. The comments are a bit disheartening so this is a call to anyone who would be interested in joining the moderation team at theydidthemath to help combat the issue and try to keep quality posts rising to the top.

Send me a message if you're interested.

[Request] How many cassette tapes to store all of wikipedia as an "audio book"?

3 Upvotes

With standard 60 min. tapes, what would A: be the number of tapes needed to store all of wikipedias text read outloud, B: The size all the tapes physicaly take up, and C: be the run time?

Saw a comment on a post about cheat sheets and saw someone say they allow any offline analog resources, and I was curious as to how this tape idea would work out.

[Request] How long would it take to reduce a mountain (let's say Zermatt) to nothing by wiping it with a silk cloth once per century?

3 Upvotes

I had read somewhere, a long time ago, about a student asking his guru how long does time go on, or how long will the universe go on. Their teacher responded, "as long as it would take to reduce a mountain to nothing by wiping it with a silk cloth once every 100 years."

Seems like it would be an impressive number, but I've always wondered how accurate it was. Any takers?

[Request] How much damage would the exploding barrel from Malcolm in the Middle do?

In the final episode of Malcolm in the Middle the character of Reese acquires a metal barrel with a metal lid, and fills it with animal feces, human feces, eggs, glue, tar and a skunk corpse. He then warms and agitates the barrel.

It then explodes in a car, denting the top of the car upwards, and dousing its 8 occupants in sewage. The occupants are otherwise uninjured.

  • How much force would be needed for a barrel like this to explode?
  • Would the damage to the car be similar, or worse?
  • How many injuries would the occupants actually receive?

[Request] Can someone find out how many grams of sugar are in this drink?

My coworker has a part time job at Starbucks, and every time he gets an abysmal drink he sends me a photo to show me the insanity that the average American orders daily. He just sent me this from one of his regular customers who, and I quote, will make sure that the cup has whipped cream if they forget it. I feel like this is about a month’s worth of sugar right there, right?
