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 :)

i fucking hate this you math nerds stay fuckin shit up

Lucy TRAILER 1 (2014) - Luc Besson, Scarlett Johansson Movie HD


Set in a futuristic world that is run by the mob, street gangs, drug addicts and corrupted cops, Lucy (Scarlett Johansson), a woman living in Taipei, Taiwan, 2069 AD, works as a drug mule for the mob. The drug she inadvertently takes goes into her system, changing her into a metahuman. She can absorb knowledge instantaneously, is able to move objects with her mind and can’t feel pain and other discomforts.

After 400 years, mathematicians find a new class of shapes
“ In the millennia since Plato’s time, only two other collections of equilateral convex polyhedra have been found: Archimedean solids (including the truncated icosahedron) and Kepler solids (including rhombic polyhedra). Nearly 400 years after the last class was described, mathematicians claim that they may have now identified a new, fourth class, which they call Goldberg polyhedra.”

Secret cinema found beneath Paris.
In September 2004, French police discovered a hidden chamber in the catacombs under Paris. It contained a full-sized movie screen, projection equipment, a bar, a pressure cooker for making couscous, a professionally installed electricity system, and at least three phone lines. Movies ranged from 1950s noir classics to recent thrillers.
When the police returned three days later, the phone and power lines had been cut and there was a note on the floor: “Do not try to find us.” (via)

This rock is the best fucking rock. It’s the best colour and it’s frosty which is my favourite and it makes these super cute stalagmites that look like Mario hills. It’s called Chrysocolla and it’s amazing.

FUN FACT!
Do you ever wonder why your lips and tongue sting a little when you’re eating pineapples? It’s because pineapples possess the enzyme bromelain, which breaks down meat proteins. 
Basically, when you eat pineapples, pineapples eat you right back.

Pineapples are so metal.
