Cool analysis if you happen to have cylindrical onions and infinitely long knives laying around.
I store them in the same non-euclidean drawer as my spherical cows.
Do not forget the tessaract
I keep mine next to my frictionless planes and point masses, but somtimes they roll away into the fourth dimension.
Extending the study to an onion’s actual shape, the conclusion would be conical cuts…
Banach-Tarski may be relevant here… https://en.m.wikipedia.org/wiki/Banach–Tarski_paradox
They also completely missed the point of the two additional cuts method and made the lowest cut about where the highest cut should be.
Me:
Only way this’ll make ya cry is if you stuck your hand inside while chopping.
“You’re gonna love my nuts.”
I throw it up in the air and hit it with the cleaver twice, perfectly diced everytime
Tried this method. Any recommendations for repairing a broken window and getting a cleaver out of my neighbor’s dead body? It’s, like, really stuck in there.
And here I am using a food processor to chop my onions into little uniform bits.
my knife isnt sharp enough for this
why do all that when you could just do this? it’s much faster.
Besides the fast chopping, that guy also knows that his time is worth more than the piece of onion that he discards at the end.
if you cut an onion horizontally, you’re just fighting it’s already natural layers. no good onion cutting technique cuts horizontally imo
You can get around that by quartering the onion, making the vertical cuts, turning it so the vertical cuts are horizontal, then making more vertical cuts. :)
Here’s my fav way: https://yewtu.be/watch?v=CwRttSfnfcc
Very easy, imo!
Of all things you could learn in school after all the bullying and the huge tuition cost…
Ten years later…
A new mathematics field dedicated to slicing has resulted in 3D printable replacement heart and other vital organs.
Bad testing regime. Missed whole categories, food processor, mandolin, alternating depth, etc. Include time taken and clean up needed. I cut radial, alternating 50% depth and 100% depth cuts.
I’m not fully understanding the last bit, why alternating depths?
I think I get their point. The layers closest to the center of the onion have the smallest radius, so by only going all the way with every other cut, the smaller pieces toward the center of the onion get cut half as many times.
Using my mandolin where you slightly rotate the onion after each cut works wonderfully.
I just stick it in the whirry blade thing.
For actual cooking, chop off the root part (it holds all the layers together), then perform two cuts to chop the onion in four equal pieces. Then press each quarter with your finger and it will separate into individual layers thin enough to fry in a pan.
You can even do it with two half-onions, but you’ll squish some layers when separating them, or you’ll spend too much time carefully separating them with a knife or a spoon.
I have always said that the horizontal cuts were useless, I’m glad the math backs me up.
The horizontal cuts are supposed to go much lower. Look at the diagram again and imagine the cuts below the lowest cut they did.
