    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 :)

    Goodbye #Montrose… For eight years you kept me safe and loved… close to Coffee Groundz, Caroline Collective and more… surrounded by friends who changed my life. I’m ready for new adventures with Tirza in our home in Meyerland! The adventures continue…!

    LEGO has announced that they will produce a female scientist minifigure set!

    After last year’s release of a single female scientist minifigure by LEGO, designer Alatariel Elensar submitted concepts for a full minifigure set of female scientists to the LEGO Ideas competition. This week, after more than ten thousand people voted for Elensar’s project, LEGO announced that they are putting the set into production for late summer 2014!!

    The figures above (still concepts, not the final sets) are doing what female scientists do, devoid of pink, and full of awesome. As Maia Weinstock notes at Scientific American in her rundown of the LEGO project, toy companies have an enormous amount of power to determine what children think, helping them form their ideas about how the world is, and how it should be.

    I’m proud of my favorite toy company for doing their part to inspire young minds. Sounds like we’ve got the perfect holiday gift idea, for young girls AND boys :)



    This is not a Half Pipe

    Good morning.

    Pride in Nationality. On Reddit they say this is from the World Values Survey. And someone provided a version for those who are colorblind. 

    Where is the version that accurately represents Muricans?! JK.

    This is a bit future-shock …

    A small consumer-level molecular scanner lets you analyze the objects around you for relevant information, from food calories or quality, medicine, nature etc … This could be the start of the Internet of Everything

    The Kickstarter was launched yesterday and made it’s $200,000 goal within 24 hours - the potential for this tech is huge. Watch the video embedded below to see the potential:

    Smartphones made it easy to research facts, capture images, and navigate street maps, but they haven’t brought us closer to the physical environment in which we live – until now. 

    Meet SCiO. It is the world’s first affordable molecular sensor that fits in the palm of your hand. SCiO is a tiny spectrometer and allows you to get instant relevant information about the chemical make-up of just about anything around you, sent directly to your smartphone.

    Out of the box, when you get your SCiO, you’ll be able to analyze food, plants, and medications.

    For example, you can:

    • Get nutritional facts about different kinds of food: salad dressings, sauces, fruits, cheeses, and much more.
    • See how ripe an Avocado is, through the peel!
    • Find out the quality of your cooking oil.
    • Know the well being of your plants.
    • Analyze soil or hydroponic solutions.
    • Authenticate medications or supplements.
    • Upload and tag the spectrum of any material on Earth to our database. Even yourself !

    You can find out more about the product at it’s Kickstarter page here
