The Potato Paradox | #1minutemaths | Mathematigals
Переглядів 4,6 тис.3 роки тому
A farmer gathers 100kg of potatoes which consist of 99% water. He leaves them out in the sun and the water fraction decreases to 98%. What is the new weight of the potatoes? Would you believe us if we told you it was 50kg? That's HALF of the original weight! Watch our video to understand this paradox!

I feel like the same pluse, some similar concepts could prove. outter space as we know it, has an end 🤔
Hello give you mobile nomber..... Lottry thai speak 3up
Terimakasih
I have seen this "proof" before (including Wikipedia and other sites that are copying this "proof"). I believe this flaw has been perpetuated by people because it makes them look smart, but I believe there is a flaw in your thinking. BTW: We do know the radius of the Earth (average 3,959 miles). Note that adding C + 6 does not make sense in your equations because it should be converted to an actual unit of measurement, not just "R". You cannot cancel out the "R" the way you did if you use real measurements. If you convert R1 to feet and then calculate r2 = R1 + (height), you will see the difference. The concept that R is irrelevant to the solution doesn't make any sense. Instead of trying to cancel out the R values, replace them with "feet" and you will get a more reasonable answer. There is no paradox if you do it right. The fact is that the larger the R value, the more the increase in the size of the belt will affect the height of the new belt above the old belt. Try it with a basketball and then something else larger.
The problem here is your assumption that R / (R+10) is a constant is incorrect. Note: 2 / (2+10) = 2 / 12 = 0.167. Note: 100 / (100+10) = 100 / 110 = .909. Can you do this? It is not a conundrum, just an assumption that believing that because R / (R+10) seems to be a constant, it is NOT a constant when putting real numbers in there. Also, you have to use real measurements. The usage of 6.28 feet in your video is incorrect. How did you come up with feet if you cancelled out R? Try the entire calculation using feet (convert miles to feet first), then see what you get. Sorry to burst your bubble.
The units come from the amount you want to raise the rope. It's a simple, algebraic expression. 2*pi*R where R=r+1m so the full expression is 2*pi*(r+1) the 2*pi distributes. and to see how much more we need we subtract off the original 2*pi*r <- note the lowercase, to get 2*pi*r+2*pi*1m-2*pi*r = 2*pi*1m or aprox 6.2m
I'm less intelligent now than before i watched this. This is wrong ❌ in every way possible
Please elaborate
I don't know maybe your problem is like mine, because at first reading I understood like 1%of water evaporates, but it's not. It's become 98% of water so in this case it's really 50
@@renatarossokha3119Isn't it 1% overall?
The important thing to note in this whole paradox is "Initial weight remains the same and every drying process keeps adding weight to it."
Trinston was here.
Mind breaking.

Interesting 😃.

There are a billion billion atoms to 1 square cm of air, I think there's way way more atoms out there. Good example tho 👍
The Monty Hall problem, however, is a fiction that doesn't actually exist in real life.
That is true. The reason for this is that in order for switching to be advantageous, you have to know the host's method of play. Will the host _always_ open one of the other doors with a goat, then switch. Will the host only open one of the other doors if your initial door had the prize, don't switch. Will the host open a random door? Switching is 50/50. As long as the host's method of play is not made known, all the information you have is that there are only two doors left. So, 50/50.
You have one try, one door. The House has two tries, two doors. The house then gets rid of one bad door. IF the house had the one good door, they will always get rid of their bad door thus leaving their good door for you to trade with. ( I'm using "House" as a casino reference.)

Nice. Once the rope is raised off the ground, how fast does it need to be rotating around the earth in order to stay suspended against the pull of gravity?
You don't need to just let all the 1 meter penguins hold the rope by their head all around the Earth. hahaha
@@carlrodalegrado4104 Yep. The penguins will take over the world and build a giant snow continent covering thr entire earth. That continent will come to be known as Pengea!

helpful thanks for the additional info
Is it that easy really or im just a bit high 😅
This was the best explanation of The Monty Hall Problem, great job!
I think this explination is easier to understand ua-cam.com/video/jYM1qtK1324/v-deo.html
Really well done! Thanks for the explanation :)
