16-cell

16 cell structure – Trinh Do

In four-dimensional geometry, a 16-cell or hexadecachoron is a regular convex 4-polytope. It is one of the six regular convex 4-polytopes first described by the Swiss mathematician Ludwig Schläfli in the mid-19th century. It is a part of an infinite family of polytopes, called cross-polytopes or orthoplexes. The dual polytope is the tesseract (4-cube).Conway’s name for a cross-polytope is orthoplex, for orthant complex. Geometry It is bounded by 16 cells, all of which are regular tetrahedra. It has…

“Space is limited” Trinh Do

In mathematics, four-dimensional space (“4D”) is a geometric space with four dimensions. It is typically meant to mean four-dimensional Euclidean space, generalizing the rules of three-dimensional Euclidean space. It has been studied by mathematicians and philosophers for over two centuries, both for its own interest and for the insights it offered into mathematics and related fields. Algebraically it is generated by applying…

120-cell structure – Trinh Do

  In geometry, the 120-cell (or hecatonicosachoron) is the convex regular 4-polytope with Schläfli symbol {5,3,3}The boundary of the 120-cell is composed of 120 dodecahedral cells with 4 meeting at each vertex. It can be thought of as the 4-dimensional analog of the dodecahedron and has been called a dodecaplex (short for “dodecahedral complex”), hyperdodecahedron, and polydodecahedron. Just as a dodecahedron can be built up as a model with 12 pentagons, 3 around…

HORIZON - THE HAWKING PARADOX

A remarkable story – Stephen Hawking

FAMED astrophysicist Stephen Hawking believes humans are capable of time travel. Claiming he is not as concerned about being labelled crazy as he once was, Hawking has publicly aired his second startling theory in two weeks, after last week claiming it was “entirely reasonable” to assume aliens existed. Preparing for the debut of his Discovery documentary, Stephen…

Time travel

“The secret of time” – Mr.T

  HELLO MR.HAGUE Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, generally using a theoretical invention, namely a time machine. It has a commonly recognized place in philosophy and fiction, but has a very limited application in real world physics, such as in quantum mechanics or wormholes. Although the 1895 novel The…

Australian literature

Australian literature is the written or literary work produced in the area or by the people of the Commonwealth of Australiaand its preceding colonies. During its early Western history, Australia was a collection of British colonies, therefore, its literary tradition begins with and is linked to the broader tradition of English literature. However, the narrative art of Australian writers has, since 1788,…

Porifera – Sponges

  Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/; meaning “pore bearer”). They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohylsandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in…

Archimedes’ cattle problem

Archimedes’ cattle problem (or the problema bovinum or problema Archimedis) is a problem in Diophantine analysis, the study of polynomial equations withinteger solutions. Attributed to Archimedes, the problem involves computing the number of cattle in a herd of the sun god from a given set of restrictions. The problem was discovered by Gotthold Ephraim Lessing in a Greek manuscript containing a poem of forty-four lines, in the Herzog…

Millennium Prize Problems – Mr.T

As we have known, mathematics and physics have been developed strongly since 19th century. Eventhough we could recognize many special theories, such as: quantum mechanics, relativity theory,…, there are still 7 unsolved problems. Especially, you can get 1 million dollars from the government if you can solve it as well. Generally, we can this topic…

“Death is not an end” – Trinh Do

Nowadays, human has explained many mysteries because of he modern technology. However, that doesn’t mean we could explore everything. Of course, there are still some unsolvable issue, some are nearly completed but some look like…impossible forever. Some problems look like easy too much but be careful with it.

freshwater-lungfish-500

Lungfish

Lungfish (also known as salamanderfish[1]) are freshwater fish belonging to the subclass Dipnoi. Lungfish are best known for retaining characteristics primitive within the Osteichthyes, including the ability to breathe air, and structures primitive within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton. Today, lungfish live only in Africa, South America and Australia. While vicariance would suggest this represents an ancient distribution limited to the Mesozoic supercontinent Gondwana,…

Biology

Some basically biological issues – Trinh Do

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent field.…

Tensor analysis of Mr.T and Sir.H

All objects have to stay in a 4 dimensional space, 3 of space and 1 of time. That is easy to imagine 3 dimensional space but really hard for you to think about time. Eventhough the object isn’t moving in space dimension, it is still moving in time dimension. It looks like impossible for me…

Theory of relativity

The theory of relativity, or simply relativity in physics, usually encompasses two theories by Albert Einstein: special relativity and general relativity. (The word relativity can also be used in the context of an older theory, that of Galilean invariance.) Concepts introduced by the theories of relativity include: Measurements of various quantities are relative to the velocities of observers. In particular, space and time can dilate. Spacetime: space and time should be considered together and in…

I feel lazy to talk about black holes

Properties and structure The no-hair theorem states that, once it achieves a stable condition after formation, a black hole has only three independent physical properties: mass, charge, and angular momentum. Any two black holes that share the same values for these properties, or parameters, are indistinguishable according to classical (i.e. non-quantum) mechanics. These properties are special because they are visible from outside a…
