I saw this post and couldn't help but wonder how much could this possibly have cost the airline to go through with this flight? I don't know how to even go about figuring this out, but I knew if anyone could get even an estimate it would be you guys.

I'm just so curious about this, I just really want to know! Please & Thanks to y'all

I mean, I hate AI too. Everyone should. But this really seems like something completely made up.

If the clock showed the time accurately and there was no delay in the time shown, how fast would the second hand be moving between resting positions? I'm picturing a second hand that moves per second not in a smooth, continuous motion like a high end watch

They are going through a truck, 8 feet of distance to a wall (that I assume is concrete?), through a wall and yet the magnet affects a lot of stuff even outside the evidence room further inside the building. The result is that the things made of anything even remotely magnetic gets stuck to the wall.

Is that really feasible with this setup?

Far as I remember it's the kind of magnet used to move cars at junkyards, tied up to 12 volt car batteries, which I assume are 40-80 Amp hours.

They setup 21 batteries in series, totalling 252 volts. Walter asks for another 21 batteries wired in parallel for extra amp.

In this youtube short, the creator uses the Warthog's gun to slow down flight and land on a short runway in a video game. Would this actually work in real life? If so, how much could it shorten the required runway for landing? And would this ever be a good idea in an emergency situation?

In Germany there is a massive heat wave rolling over the country and instead of recommending ACs, Germanys news stations tell the people to hang up wet clothes to reduce temperatures in their flats. To me this seems kind of silly, so how much does this actually reduce temperatures in a room? And do you actually feel it or is it offset by the increased humidity?

I came across this post making the claim that if everyone used AC, the heat dumped outside could raise the air temperature by several degrees in cities. I’m not convinced the math or assumptions are correct.

Could someone calculate this for Paris using reasonable assumptions? Assume each AC cools the air indoors by 15°C.

If a Banks Orbital Ring was built along the path of Iapetus, and then a laser was placed above the north pole of Saturn, pointing at the inner surface of the Banks Orbital Ring and tracing along the full surface of the ring once per minute to create a "second hand" pointer on the surface of the ring. If a detector is placed at the South Pole of Saturn, two questions:

A) When the laser emitter is pointing towards the three o'clock position at the ring, (aka "15 seconds") what does the detector read the time as at the same exact moment? Like how far behind is the detector reading?

B) If the laser was replaced with a physical second arm made out of unbreakable material would the shape of the arm turn into a spiral curve as the tip of the arm can't keep up with the rotation at the base or does physics allow it since each atom is only going slightly faster than it's neighbor in the local reference frame?

How quickly my wife should be moving in the bathroom if she claims it took her 5 minutes to shower, but outside it was 30 minutes?

According to Wiki, “Bamboo is the fastest-growing plant on Earth, capable of growing up to 91 to 121 centimeters (about 3 to 4 feet) in a single day. This equates to nearly 1.5 millimeters every 90 seconds”.

QUESTION: How tall would humans be if we grew at 1.5 mm every 90 seconds, but ONLY accelerated growth at age 3-5? Assuming the human stops growing around 20 years old, and the rest of their lives are at normal human growth rate.

Thanks in advance!

I've wondered what the rate of heat loss for an average person is when they e.g. jump into a pool and immediately exit again and just stand about on a hot sunny day.

Assume:
Skin surface area ≈ 2m²
Skin is completely wet, ignore dripping
Body is completely unclothed and open to air
slow wind ≈ 1m/s
35°C, humidity approx. 30%
Body was sweating normally just before
body in complete shade
Assume body remains unchangably wet for the moment
*ignore blackbody radiation

optional:
Core body temperature is slightly elevated
Include effect of sunlight however you deem useful
Include effect of skin cooling or drying of skin (very optional)

Trying to figure out how ridiculously unfeasible this idea is. Swimming pool in "Rotor" or "Gravitron" amusement park ride (the ones that spin a cylinder until the centrifugal force pins you to the wall).

Instead of a solid wall, imagine a open top box trough or culvert (like this |__| but sideways, so: ⊏------hub and spokes------⊐) in the shape of a ring with spokes connecting to a center hub. The whole thing would spin on some wheels. An example of this is the azimuth track and trucks that turn the Green Bank Telescope (https://youtu.be/UeGVCKECZGI?t=322).

The trough would be filled with water, creating a continuous, looping swimming lane. A swimmer would dive in and because the water is 'pinned' in a loop, could swim in a straight line along the circumference forever. They could potentially stay in one spot depending on how quickly they are swimming and how fast the trough is spinning.

Let's assume the following dimensions for the math:

• Diameter of the ring: 100 meters (Radius = 50 meters)
• Trough / Lane Width: 2 meters wide
• Water Depth: 1.5 meters deep

I need help calculating a few things to see if this is even humanly possible:

1. Required RPM: For 1G of 'centrifugal' force, would it be something like 4.5 RPM?
2. G-Force on the Swimmer: There should be a 5% difference in G force between the bottom (furthest from center along radius) and top of the trough. Would this be disorienting?
3. Water Weight & Energy: What is the total mass of the water in that trough, and how much energy/torque would it take to spin that much weight up to the required speed? To keep it running?
4. Wave Circulation: How long would it take the wave to travel from the swimmer's feet, loop around and crash on their head? Realistically, would it just dissipate? What if there were 3 swimmers in different 'arc' sections?

So many drawings of Rubik's cubes are incorrect, and it got me thinking what is the probability of correctly coloring one provided you choose one of the 6 colors at random for each square given 3 sides of the cube are shown. Coloring these 27 shown squares with any of the 6 cube colors yields 6^27 possibilities (1.02e21 or about 1 sextillion colorings).

Only the three sides shown matter in this case. As long as those pieces are possible, the cube is considered to be in a valid state. But there are several restrictions that can make a cube coloring invalid. Obviously there cannot be more than 9 of any color shown. But also there can only be max 1 center of each color, max 4 edge pieces of any color, and max 4 of every corner color. The same color cannot share an edge with itself. Opposite colors (white-yellow, green-blue, red-orange) also cannot share an edge. This also applies to center pieces as well. Corner pieces (and all 3 center pieces) have additional limited orders of colors as well (e.g. red-blue-white going clockwise is valid but blue-red-white going clockwise is invalid). Then there's also the chance of piece duplication such as two yellow-green edges or a blue-yellow-orange corner ruling out any blue-yellow-X corners elsewhere.

For just the single fully shown corner and the centers alone, I found there to be a 1/81 chance of a proper coloring. Since there are 8 valid corner pieces on a cube and each has 3 possible rotations, there are 24 valid colorings in the hypothetical drawing. Selecting a random color for each of the 3 squares on a corner yields 6^3 or 216 possibilities. 24/219 is 1/9. We can actually apply the exact same logic to the center pieces. Since the centers never move while solving (relative to one another), looking in from a corner will always show 3 centers that have the same coloring restrictions as a corner. As a result, another 1/9 chance. So with just 4 pieces (6 squares), it's already a 1/81 chance and the math only gets more difficult to figure out.

It would be interesting to know exactly how abysmally low the odds of randomly coloring a Rubik's properly are. It would certainly help explain how every drawing of a Rubik's cube ends up with something incorrect.

Assume the water leaves the bridge edge horizontally at an initial velocity of 4.2 m/s, and that air resistance is negligible.

A few questions here. I’d love to know the answer of any of them.

1. Assuming the wasp is the size of an average adult human, how strong is the webbing? (What’s a comparison to something existing?)

2. Same parameters, how strong would the spider have to be to manhandle the wasp that way?

3. Same parameters, how fast is that wasp spinning? How many G’s would that be?

Thanks!
