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:

  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.
  2. 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.
  3. 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.
  4. 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.
  5. 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 :)

‘The right to be handsome’: Clothing for gender non-conforming people on the rise

A great bit by PBS about finding that perfect-fitting outfit through customized/tailored clothes.

Rachel Tutera says it wasn’t until she started wearing boy’s clothes as a pre-teen, that she started to feel like the most authentic version of herself. Yet the 29-year-old says shopping for clothes in the men’s department left her feeling insecure and self-conscious. Nothing ever fit her proportions. So she was resigned to thinking that’s just the way it was.

So she approached the New York based made-to-order-men’s suit company, "Bindle and Keep" convincing the owner that he was overlooking an under-served market…Not only masculine women, but also transgender men and other gender non-conforming people who want well-fitting, men’s suits.

Model Andreja Pejic comes out publicly as a transgender woman, shares her experience with media and Facebook fans
By Dani Heffernan, Media Strategist at GLAAD |


July 24, 2014





Fashion model Andreja Pejic tonight shared her life and experience as a transgender woman exclusively with Entertainment Tonight, People.com and Style.com. The acclaimed model who has appeared on covers of Elle and French Vogue, announced that she will only be modeling women’s fashion going forward and that her agency supports her transition. She also told the press that she is supported by her family in Australia and friends around the world.
Andreja drafted a message for her Facebook fans and Instagram followers. She will now be tweeting from @andrejapejic.
GLAAD worked with Pejic and her team this week as she prepared to tell her story.
She told GLAAD:  "To all trans youth out there, I would like to say respect yourself and be proud of who you are. All human beings deserve equal treatment no matter their gender identity or sexuality. To be perceived as what you say you are is a basic human right."
She also posted a selfie on Facebook with a message to her fans:"As a transgender woman I hope to show that after transition (a life-saving process) one can be happy and successful in their new chapter.”
Pejic has received international attention modeling men’s and women’s collections on runways and in ad campaigns. She began modeling in 2007, and since then has been named to the Out 100 and received a NewNowNext award for style. She has been on the covers of Elle, New York, and many more, and walked the biggest international runways. In 2013, she co-starred in David Bowie’s music video, “The Stars are Out Tonight,” alongside Tilda Swinton.
Pejic is one among many trans models finding growing acceptance as visibility of trans people in the media increases. In 2008, Isis King made headlines as the first trans woman model to compete on America’s Next Top Model. In 2010, model Lea T came out to the world as transgender in French Vogue. In January of this year, a Barney’s New York ad campaign featured all trans and gender non-conforming models. Earlier this year, supermodel Naomi Campbell spoke out at the GLAAD Media Awards in support of Carmen Carrera and other trans models.
As blogger and advocate Monica Roberts has pointed out, the way was paved by trans models like Caroline Cossey, Tracy Africa Norman, and Roberta Close in previous decades, and now models like Ines Rau, Arisce Wanzer, Valentijn De Hingh, Geena Rocero, and many more are a growing presence in the fashion world.

I haven’t been active lately…

I have been at home. My mom is touring the east coast doing healthcare stuff with her organization. So it’s been me and my brother alone at out house for the past week and a half.

I’m trying to repair out relationship and so far so good. I’m skeptical because I have seen the worst that can come out of his mouth. He said he loved me and that he initially hated that I was trans. Now he accepts it. He did say this while very drunk, he normally says horrible things when he drinks so it’s a change.

I have been sick(fever,cold) since last Saturday,so I haven’t been going out. Hopefully I am fine by tomorrow, a bunch of friends are going out and we are checking out comic con events.

I saw that there is a orphan black event tomorrow. I haven’t seen the show but I see it on tumblr all the time so it must be good.
