I think my Fitbit is trying to tell me something…
Mathematically Correct Breakfast - How to Slice a Bagel into Two Linked Halves. If a torus is cut by a Möbius strip it will split up into to interlocking rings.
It is not hard to cut a bagel into two equal halves which are linked like two links of a chain. Figure 1:
- To start, you must visualize four key points. Center the bagel at the origin, circling the Z axis. A is the highest point above the +X axis. B is where the +Y axis enters the bagel. C is the lowest point below the -X axis. D is where the -Y axis exits the bagel.
- These sharpie markings on the bagel are just to help visualize the geometry and the points. You don’t need to actually write on the bagel to cut it properly.
- The line ABCDA, which goes smoothly through all four key points, is the cut line. As it goes 360 degrees around the Z axis, it also goes 360 degrees around the bagel.
- The red line is like the black line but is rotated 180 degrees (around Z or through the hole). An ideal knife could enter on the black line and come out exactly opposite, on the red line. But in practice, it is easier to cut in halfway on both the black line and the red line. The cutting surface is a two-twist Mobius strip; it has two sides, one for each half.
- After being cut, the two halves can be moved but are still linked together, each passing through the hole of the other.
It is much more fun to put cream cheese on these bagels than on an ordinary bagel. In additional to the intellectual stimulation, you get more cream cheese, because there is slightly more surface area.
Topology problem: Modify the cut so the cutting surface is a one-twist Mobius strip. (You can still get cream cheese into the cut, but it doesn’t separate into two parts). See more at: Mathematically Correct Breakfast: How to Slice a Bagel into Two Linked Halves by George W. Hart.
Maybe, that’s one of the reasons why I love bagel :)
Just stuffed my face with my first attempt at chillies relleños con pollo. Still need to tweak the recipe some before I post it but soon.
2 cups raw almonds
2 tbsp Sriracha
2 tbsp tamari (or soy sauce)
2 tbsp olive oil
Preheat oven to 300F. Combine Sriracha, tamari, and oil. Mix well. Add the almonds and toss until completely covered. Spread almond mixture in a single layer on a parchment paper lined baking tray. Bake for 30 minutes stirring halfway through. Cool on a paper towel.
With a show that’s been around for as long as Doctor Who has, there have been a lot (A LOT) of episodes. And maybe at some point you’ve thought to yourself “Hey, I wonder what episode premiered on my birthday!” We think things like this all the time.
Up until now the question plagued our minds with no easy answer. We spent many sleepless nights pondering the thought, tossing and turning in our Adipose beds thinking “What episode premiered on our birthday? What episode premiered on our birthday‽ How can we possibly find out‽”
This was a clear moment of weakness, as we forgot that the internet existed and it was something we could just search. But why do that when you can just go to tardisday.com? Enter your birthday and bam! It’s as easy as
How cool is this?
The perfect metaphor for life.
