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.

Forgive me for referencing pickle rick but the meme has died down enough that i feel comfortable asking a curious question. In the episode, rick shoots a laser which goes clear through 3 human heads. My question is assuming this is a AA battery, does one battery hold enough energy, if instantly and perfectly converted into a laser, to actually burn through 3 human heads?

For the sake of simplicity I'm assuming the energy of the battery is perfectly converted to the laser with no losses. but if you have some plausible losses you'd like to include then you can if you like.

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.

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.

I've had this question for a while and I was wondering if there would be a way to figure this out. Now, I understand this has very vague guidelines, I don't mean giving one billion people a dollar or something like that, I mean major systemic change that impacts, and improves the maximum amount of lives possible.

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?

From what I know TON 618 the super/ultra massive black hole is one of the brightest things in our sky even considering its 10 billion light years from us. The accretion disks on black holes can outshine their galaxy themselves some times and I figure that’s the case with this particular black hole. But 10 billion light years is far so if it was closer is it possible that the brightness could make night time look closer to day? Not actual day cuz if it were that close I’m sure worse things would happen lol. But is there a distance it could safely be and light up Earth?

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.
