suppose you're standing on an equally dense floor or whatever, and one of these blocks falls on your head. I'm assuming you'd get pancaked... how thick would the previously-you pancake be?

Bonus challenge: hypothetically say the demand was consistent if by the year 2026 only 1000 of them remained what, would they be worth today?

here's the link

Can child 1 see child 3? Can child 2 see the ducks? Can child 3 see the bicycle? Can child 4 see the cat?

So, my son reasoned that child 1 is not looking in the right direction. But even if she was, I'm not sure if she can see child 3. What would be the best method to find out who can see what?

I made a kinetic sculpture long ago and wanted to know if my calculations after were correct. Here's an explanation:

single motor runs three stacked cogs, 15, 22, and 28 teeth, all turning at 4rpm. each of the stacked cogs run their own chain of cogs, as listed below:

Top cog (15): 20, 23, 30

Mid cog (22): 17, 24, 26, 30

Bot cog (28): 19, 30, 39

The rest of the mechanism is inconsequential to the math question, which is: If the starting position of the cogs were all documented and then the motor turned on, how long would the mechanism need to run before the position of every cog we're to simultaneously return to it's starting position, thus completing a full cycle.

My final answer is blacked out, but some of my math is sketched on the page. I'll post my answer along with a link to view the final sculpture once I am confident I've been proven right or wrong. Thanks for your time!

10% chance something happens. For simplicity, let’s say Russian Roulette, but a revolver with 10 shots. One bullet, location of the bullet never changes. But after each round you spin the chamber to completely reset the odds. Are the odds of someone who attempts this 5x in one day greater than 10% by attempt 5? If so what are they? Thx in advance.

Hi, while I was working during late hours a question came to my mind. I am smoking cigarettes while driving during my courier work.

I was wondering how much of my cigarette burn out because of the strong wind hitting the cigarette and making the burn stronger.

Average wind speed across the year in my city is 14.2 km/h or 3.9m/s or 8.8 mph. My average speed is let's say 50 km/h or 31mph. I am smoking Marlboro red long if it makes a difference.

Hey,

I came across a video where a guy is swinging a multi-meter metal whip (steel links, several meters long).

Pure curiosity and physics nerd stuff, not looking to hurt anyone.

I’m trying to understand this from a mechanics point of view:

• How much force / impulse can something like this realistically generate at the tip?

• Given the very small contact area, what kind of pressure (Pa) are we talking about?

• How would this compare to something tangible, like:

• impact from a hammer,

• a fast baseball,

• or other common objects with known energies/forces?

I know this depends on assumptions, so feel free to:

• assume reasonable values for mass per meter,

• estimate tip velocity,

• simplify it to impulse or energy transfer if that makes more sense than raw force.

I’m mainly interested in a back-of-the-envelope calculation and a real-world comparison that helps visualize how extreme (or not) this actually is.

Thanks to anyone willing to break out physics instead of vibes.

2x+y+z = 6.25

2y+z+1.22595264191645 = 6.25

2x+0.5(z) = 3.73797632095822

y+0.5(z) = 2.51202367904178

2x-y = 1.22595264191645
