Crazy, Cool and Weird Stuff

In Marvel movie The Avengers, it is stated that the Tesseract contains an unimaginable power and can be used as weapon of mass destruction if the power can be unlocked. Well, the tesseract that i'm refering to is not in the movie but rather the one in field of geometry.

According to wikipedia, a tesseract is a four dimensional analog of the cube and sometimes is called 8-cell, regular octahoron or cubic prism. Tesseract is a four dimensional hypercube, (cube with dimension higher than 3) and first proposed by Charles Howard Hinton, a British mathematician in the 19th century.

A tesseract can be unfolded into 8 cubes in 3D space, the same as a cube unfolded 6 squares in 2D surface. The image below shows how a tesseract can be build from 1 dimensional space until the first cube projection in 4 dimensional space.

How to draw a tesseract from a single point ie one dimension.

There are other types of tesseract for example truncated tesseract and rectified tesseract in which they have different Schlafli Symbol and Schlegel diagram.  The existence of higher dimension is by far an abstract concept and none have observed these higher dimensions. Nonetheless, the mathematics suggests the possibility and therefore could exist in this vast universe.


p/s: I read somewhere in which lower dimensional object couldn't possibly see the higher dimension but the higher dimensional object can definitely see the lower one. Not sure how this implicates the existence of higher deity though. 

For the past hundred years, many scientists tried to do alchemy, in which the ultimate aim is to create a philosopher's stone, an object powerful enough to convert normal metal to gold or silver. The stone also is believed to hold the secret of immortality through elixir of life. Though not all part from alchemy is understood nowadays, it did provide a foundation for modern science and chemistry.

Nonetheless, people are still trying to find ways to create gold because after all, gold is considered high value item and represents the wealth of an individual. Unfortunately, the status may change due to recent finding at Michigan University. The finding, which is a bacteria named Cupriavidus metalliduransc (right?) is found to be able to produce gold nugget through microbial processes.

"Gold nugget" after the microbial alchemy

Well, the amount, as you can see from the picture is not much compare to the gold that you'll find in nature but with more research, the capability to turn something into gold, though amazing, may bring impact to world's economy.

Gold nugget found in nature

The researchers presented their finding as an art project called The Great Work of Metal Lover by using a portable lab house where the bacterium performs the "microbial alchemy" thingy. And luckily, the researchers said that replicating the bacterium's actions on a larger scale would be impractical and cost prohibitive.

Dawn chorus refers to a phenomena that occurs during sunrise and with proper but unsophisticated equipment, you can hear a music played by the Earth.


The music is believed to be generated by interaction between high energy electrons that trapped in the Earth's magnetosphere and electromagnetic field from solar wind. Well, ignore the scientific jargon for now, chill and listen to the song of the earth.

P/s: I'm not grasping the how this music is created just yet. But you are welcome to read about it here and here.
