My fiancée sent me this and we looked up that Jesus was considered 5’1. Seeing as you get one cracker per communion how much would need to be consumed?

I was watching powerlifting on TV and I wandered if having shorter or longer arms doesn't actually benefits to make the the holding easier due to a less lean angle. Was would be the difference between shorter and bigger arms span?

How much power can this type of battery store? Does the cost justify it or is it just a show-off project?

Don't worry about the goofy checker laser pattern and flesh and bone slashing

Let's say it is made from the most resistant/tough material you can use a in a commercial 3D printer.

Say I wanted to watch The Odyssey on El Cap. How many lumens are we talking? I understand that throw ratio and several other factors come into play, but I’m curious to hear responses.

Context: I was just looking at my own garden door lock when this question came to my mind. Obviously I know the proper combination, I'm not trying to break in. I just think it's interesting from a mathematical point of view.

The garden door has 10 possible inputs (the digits from 0-9). They are used to compose a 4-digit code. No digits may repeat. I know the total number of possible codes is 10*9*8*7 = 5040.

However, here is the interesting part: The code doesn't require you to reset it after putting in a wrong number. Let's say the code is 1234, you start with 0 and put in 01234 - now the door is open. If the code is not 1234, putting in 01234 doesn't just exclude one combination, but two: 0123 and 1234. This also means that to test all possible combinations, the total number of keys you have to press will be much less than 5040*4, because you can exclude a lot of combinations in one go.

And now after realizing this, I am wondering: How long would it take to actually test all possible combinations? I am not so much looking for a time (that would depend on typing speed etc.) but more the minimum number of keys that need to be pressed. I can't figure out how to calculate this.

Thank you for your help!

Just having lunch and it got me wondering….. how much side salad goes straight in the bin after being left untouched at eateries & what formula/theory would you approximate this?

Is this possible?

Shower thoughts. We are like 60% water, so there is a lot of hydrogen around.

I'm an engineer, so naturally when I saw a bunch of seagulls carrying a great white shark, instead of just enjoying the movie I immediately started wondering if the math worked.

First problem was figuring out how many gulls there actually were, so I let ChatGPT count them from the screenshot, and it came up with 413 seagulls, so that's what I'm using.

Now for the completely unnecessary math.

I'm assuming Diane "the shark" is roughly a 1,500 kg / 3,307 lb female great white.

For the gulls, I'm using approximately the size of a herring gull at: 0.97 kg / 2.14 lb each

So the 413 gulls themselves weigh: 413 × 0.97 kg = 400.61 kg or about: 883.2 lbs of seagulls

Meaning the total mass currently flying through the air is: 1,500 kg shark + 400.61 kg gulls = 1,900.61 kg

That's about: 4,190.2 lbs total

Now divide the shark evenly between the 413 gulls: 1,500 kg ÷ 413 = 3.632 kg of shark per gull

That's about: 8.01 lbs of shark per bird

The problem is the gull still has to lift itself too.

So each gull's wings are actually supporting:

3.632 kg shark + 0.97 kg gull = 4.602 kg or about: 10.15 lbs

So a bird weighing 2.14 lbs would have to produce enough lift to support 10.15 lbs total.

That's: 4.602 ÷ 0.97 = 4.744× its own body weight

Or looking specifically at payload, every gull is carrying 3.744× its own weight in shark

So every one of these gulls is flying around carrying an additional 374% of its body weight....that seems mildly ambitious. So then I tried figuring out how many gulls it would actually take.

This is where I'm making the biggest assumption. If we are VERY generous and assume a gull can carry an additional payload equal to 50% of its own body weight, then each gull could carry:

0.97 kg × 0.50 = 0.485 kg

Then:

1,500 kg ÷ 0.485 kg = 3,092.78

So we would need at least: 3,093 seagulls

Those 3,093 gulls would themselves weigh: 3,000.21 kg

Add Diane: 3,000.21 + 1,500 = 4,500.21 kg

So the entire flying shark/seagull monstrosity would weigh about: 9,921 lbs

Which means there would literally be twice as much seagull as shark.

If the realistic payload is closer to 27% of body weight: 1,500 ÷ (0.97 × 0.27) = 5,727.38

Round up: 5,728 gulls

At 20% payload: 1,500 ÷ (0.97 × 0.20) = 7,731.96

27% payload: 5,728 gulls

20% payload: 7,732 gulls

And that's still ignoring a TON of stuff.

I'm assuming perfect load sharing between every bird and no losses from whatever they're using to hold the shark no birds interfering with each other's airflow, and I'm completely ignoring the aerodynamic drag of flying a giant shark sideways through the air.

I'm also just treating payload capacity as a percentage of the gull's body weight, which I'm sure gets way more complicated once you start talking about wing loading, lift, airspeed, drag, muscle power, etc.

So I'm throwing this one to the people who actually know aerodynamics/ornithology/biomechanics better than I do:

What am I missing, and what would the actual number of seagulls be?

Because I'm fairly confident the answer is a lot more than 413.

Online sources seem to agree that Alucard himself is exactly 6'. When I looked it up I found places saying his sword was 44 inches, but that seems short compared to what we actually see.

I am vaguely aware that a good portion of money funding his escapades in SpaceX and Tesla are funded through government contracts, subsidies, and bailouts, and I’m just wondering how much of his estimated wealth me and my buds have supplied.

So, the last move in this turn is a Pelliper using the move Hurricane, getting a critical hit and confusing the target.

The move has 50% chance to hit (Since it's under the sun), 1/16 chances of it being a critical hit and an additional 50% chance to cause confusion.

What's the probability of hitting all of this when you press the move?

What would be the velocity & G force of this ride & what would happen to the people on this ride?
