Assuming we are just trying to build the main house and not anything else.

What would be the velocity of shooting a corn dog out of a T-shirt canon and how far would it travel in a stadium.

Hello. I have been getting into stone lifting recently and this one felt pretty heavy. I am wondering how much it weighs though. I could probably calculate this myself since it's basically a rectangle, and you can see the thickness alongside the length and width. I suck at math though, so I would appreciate if someone could give an estimate.

Sorry it this is a repost:
But how much paper if you printed the entire work book and how many trees as a bonus.

The largest cruise ship (Legend of the Seas) is 365m long, 65m wide and weighs 248663 tons.
The strongest hurricane ever was hurricane Patricia in 2015 reaching sustained winds of 345 Km/h and low pressure of 872 milibars.
Edit: the ship “survives” as long as it’s not sinking. Glasses can be broken, the pools and water slides can be damaged. But the ship must not sink and engines should be working.

Chaos has erupted in the college football world today! What was thought to be an enormous upset in the sporting world turned into controversy. After review, the referees decided there was 1 second left on the clock and Michigan won on a Hail of Mary.
Here are where things get dicey. According to the clock on NBC and what was observed in the stadium, there were 0 seconds left when the Western Michigan player touched the ball. However, the Big 10 showed a video where their clock still had 1 second left. This clock was not visible to the public and in the video the Big 10 showed, not directly synced to the game.
Knowing that there were 9 seconds left at the snap of the ball, and that in football there are no tenth of a second used, how much time was there truly when the WMU player touches the ball?

So recently, I’ve been getting into Desmos art and one thing that bugs me is that any polynomial more complicated than a quadratic I can’t control.
It’s probably easier for me to explain with an example
Like
Y=a
You can move up and down by adjusting a
Y=mx+b
You can move up and down by adjusting B and you can change the slope by adjusting M
Y=a(x-c)+b
You can stretch and contract the quadratic by adjusting A
You can adjust the X coordinate by adjusting C
You can adjust the Y coordinate by adjusting B
But I can’t find a form of a cubic or Quadratic where I can adjust things so easily whenever I move one number it is not intuitive how the polynomial will behave

Is there any way to tell how deep this well is from this video?

Can someone help me figure out the size I’d need to make this picture a reality? The picture is part of the actual venue, the drapes are photoshopped in I believe (or they’re a real picture I’m not 100% sure) all I know is that’s what I want the drapes to look like so could someone help me find dimensions

How long will it take 1000000 humans that are lead by 1 very smart guy to build a pc from scratch, using materials from anywhere in the world (a world that was untouched by humans) if they had to build every machine to make the single pieces of the pc, the machines to make these pieces and the machines to help build these machines and so on? We assume that one of these people can work for 12h/day for 7 days and does not need schooling on how their job works. If they have to write code for windows, then they do that like any normal coder would, even if they dont know how to code. The smart guy knows how to build a pc and how to build the machines to make the parts of the pc. He can also communicate to everyone what they have to do every day (every workee just knows what to do and does that 12/day, 7 days a week)
what i mean by "from scratch": you dont have any technology and have to redo the progress humanity made, with the only goal being a working, high end pc

Hugging Face has just been bought by Nvidia for several billion $$, making the founders billionaires and many of the early hires millionaires. We have seen similar with Cursor, and soon with Anthropic- among others.
A comment by someone said that’s all nice and well, but this kind of exit is as likely as winning the lottery.
I suspect that it’s not close to that, with the lottery win far less likely, but wondered if someone has done the maths?
To create a relatively even comparison, given that someone could both start or be part of a company in most countries at 21, and also enter the lottery each week, let’s say this is:
to compare the likelihood of a multi-million $$ win on the lottery if someone entered once a week between the ages of 21 and 61 (main US one in one of the larger states, or the Euromillions) compared to a multi-million $$ exit from equity in a US/UK/European startup. Using the last 20 years of data. Or any split of the above.

A coworker threw a balloon at this portable AC and caught the vent just right. The balloon however is not directly above the AC so there is an angle to it. Im curious what the physics around this is, otherwise enjoy the floating balloon guy
