Why is Maxwell's Theory so hard to understand?
The modern view of the world that emerged from Maxwell's theory is a world with two layers. The first layer, the layer of the fundamental constituents of the world, consists of fields satisfying simple linear equations. The second layer, the layer of the things that we can directly touch and measure, consists of mechanical stresses and energies and forces. The two layers are connected, because the quantities in the second layer are quadratic or bilinear combinations of the quantities in the first layer. To calculate energies or stresses, you take the square of the electric field-strength or multiply one component of the field by another. The two-layer structure of the world is the basic reason why Maxwell's theory seemed mysterious and difficult. The objects on the first layer, the objects that are truly fundamental, are abstractions not directly accessible to our senses. The objects that we can feel and touch are on the second layer, and their behaviour is only determined indirectly by the equations that operate on the first layer. The two-layer structure of the world implies that the basic processes of nature are hidden from our view.

How to Read Mathematics
Mathematics has a reading protocol all its own, and just as we learn to read literature, we should learn to read mathematics.  Students need to learn how to read mathematics, in the same way they learn how to read a novel or a poem, listen to music, or view a painting.  Ed Rothstein’s book, Emblems of Mind, a fascinating book emphasizing the relationship between mathematics and music, touches implicitly on the reading protocols for mathematics.

Deep Learning in a Nutshell – what it is, how it works, why care?
the big challenges with traditional machine learning models is a process called feature extraction.. Deep learning is one of the only methods we can circumvent the challenges of feature extraction.. because deep learning models are capable of learning to focus on the right features by themselves, requiring little guidance from the programmer.. Finding out what those weights should be is the hard part of the problem, and that's done through a process called training.

This short introduction to category theory is for readers with relatively little mathematical background. At its heart is the concept of a universal property, important throughout mathematics. After a chapter introducing the basic definitions, separate chapters present three ways of expressing universal properties: via adjoint functors, representable functors, and limits. A final chapter ties the three together.

[Matthew Kirk] Why did I write a Machine Learning Book in Ruby?
This is the network effect. Basically the tool is useless unless people use it. But the network effect doesn’t apply to coding. Sure there is some benefit to being able to google the solution to a particular nltk error code you are getting. But Ruby has similar tools as well. The main difference is that you don’t get everything in one easy-install command. For instance Ruby has libsvm, ruby-fann (neural networks), tlearn (neural networks), ai4r, algorithms (k-d tree to do KNN), bayes_motel, NArray, NMatrix (new but promising), and others. If you really want more you can use JRuby to get into the massive amount of Java code that sits out there."

[Setosa] Markov Chains - A visual explanation by Victor Powell
Markov chains, named after Andrey Markov, are mathematical systems that hop from one "state" (a situation or set of values) to another. ... on top of the state space, a Markov chain tells you the probabilitiy of hopping, or "transitioning," from one state to any other state ... real modelers don't always draw out Markov chain diagrams. Instead they use a "transition matrix" to tally the transition probabilities. Every state in the state space is included once as a row and again as a column, and each cell in the matrix tells you the probability of transitioning from its row's state to its column's state. So, in the matrix, the cells do the same job that the arrows do in the diagram. ... One use of Markov chains is to include real-world phenomena in computer simulations."

[知乎專欄] 如果看了這篇文章你還不懂傅里葉變換,那就過來掐死我吧 - 與時間無關的故事
如果我說我能用前面說的正弦曲線波疊加出一個帶90度角的矩形波來,你會相信嗎?你不會,就像當年的我一樣。但是看看下圖 ... 隨著疊加的遞增,所有正弦波中上升的部分逐漸讓原本緩慢增加的曲線不斷變陡,而所有正弦波中下降的部分又抵消了上升到最高處時繼續上升的部分使其變為水平線。一個矩形就這麼疊加而成了。但是要多少個正弦波疊加起來才能形成一個標準90度角的矩形波呢?不幸的告訴大家,答案是無窮多個。不僅僅是矩形,你能想到的任何波形都是可以如此方法用正弦波疊加起來的。這是沒有接觸過傅里葉分析的人在直覺上的第一個難點,但是一旦接受了這樣的設定,遊戲就開始有意思起來了。"

The 960 Grid System is simply a way to lay out websites using a grid that is 960 pixels wide. The reason it’s 960 pixels wide is because the number 960 makes for a lot of clean divisions utilizing whole numbers when factoring in column widths and margins. And it fits nicely on the majority of screens. ... When you look at the diagrams above, consider each of the dark blue horizontal bars as a CSS class in the 960 Grid System.

[The Biggest Ideas] You Have Three Brains
One thing is clear though: you have three brains. There are three brains nested within your skull: the lizard brain, the dog brain, and the human brain... Consider this: language lies in the human brain, but emotions lie within the separate dog and lizard brains. So the emotions are in a different world from language entirely. Not only that, reason too lives in the new human brain while emotions live in the older brains... The older brains cannot speak. They can only feel and act. This is where the self-contradictory nature of so much human behavior comes from... The way the neo-cortical memory degrades while the limbic memory lasts may also have something to do with the differing ages at which certain human capacities peak... Can we better integrate our three brains? It turns out that meditation integrates the brains. It rewires and harmonizes them."

Infinity (symbolically represented with ∞) comes from the Latin infinitas or 'unboundedness.' It refers to several distinct concepts (usually linked to the idea of 'without end') which arise in philosophy, mathematics, and theology."

[Wikipedia] The Emperor's New Mind
a 1989 book by mathematical physicist Sir Roger Penrose. Penrose presents the argument that human consciousness is non-algorithmic, and thus is not capable of being modeled by a conventional Turing machine-type of digital computer. Penrose hypothesizes that quantum mechanics plays an essential role in the understanding of human consciousness. The collapse of the quantum wavefunction is seen as playing an important role in brain function."

[Wikipedia] Empirical limits in science
In philosophy of science the empirical limits of science define problems with observation, and thus are limits of human ability to inquire and answer questions about phenomena. These include topics such as infinity, the future and god."

[Wikipedia] Chaos theory
chaos theory describes the behavior of certain dynamical systems – that is, systems whose state evolves with time – that may exhibit dynamics that are highly sensitive to initial conditions (popularly referred to as the butterfly effect)"

[Wikipedia] Cognitive science of mathematics
the study of mathematical ideas (concepts) using the techniques of cognitive science. It proposes to ground the foundations of mathematics in the empirical study of human cognition and metaphor, and to analyze mathematical ideas in terms of the human experiences, metaphors, generalizations, and other cognitive mechanisms giving rise to them... If human intuition appears to be inconsistent with formal mathematics, this gives rise to the question of where formal mathematics comes from."

[Wikipedia] Self-reference
Self-reference is possible when there are two logical levels, a level and a meta-level. It is most commonly used in mathematics, philosophy, computer programming, and linguistics. Self-referential statements can lead to paradoxes."

[石頭閒語] 維根斯坦眼中的數學並非不可言的
維根斯坦在《邏輯哲學論》中說「'語言的邊界就是世界的邊界'」。數學所能表達的意涵有其邊界,在邊界以外之事,「'不要想,但要看'(《哲學研究》)」。" - comments 的部份也不錯。

[聽雨塵心@含藏識] 【數學故事】哥德爾不完備性定理淺釋
彭羅斯對強AI質疑的論點主要基於兩個方面,第一個方面來自數學和邏輯學,他使用著名的哥德爾不完備定理(Godel Incomplete Theorem)和圖林的停止問題(Turing's Halting Problem)證明了帕拉圖理念世界(Platonic World)裡存在著大量不可計算的問題,即不能使用計算機算法獲得由人類直覺天才取得的大多數數學成果,而這,尚不包括人類對藝術等領域的認知和理解。... 彭羅斯一步一步地把嚴密的數學推理用到證明計算機不能代替人腦作數學思維。彭羅斯這一推理雖然只用在數學直覺上,卻也可以同樣用在人的其他意識經驗上面,例如,領會特徵(sensory qualia)、痛苦和快樂的感受、意志的感情(feelings of volition)、意向性(intentionality)等上,只是因為這些意識特徵不像數學直覺一樣,有與邏輯較明顯劃分的界線和符號推理工具,能夠被彭羅斯拿來作為有力的武器罷了。"

[CCIM-網絡基督使團] 哥德爾不完備性定理(theorem of incompleteness):人間邏輯與神聖三一邏輯
什麼是真呢?在哥德爾之前,都相信凡是真的都能被證明,這以大數學家希爾伯特(David Hilbert, 1862-1943)為代表的形式主義(Formalism),主張一切數學都必須被證明建立在公理化的基礎上。主張邏輯原子主義(Logic Atomism)的羅素(Bertrand Russell, 1872-1970),則相信一切語言都可建立在最基本的意義原子層次上,並以邏輯符號表達... 哥德爾的傑出貢獻在於提出:凡是命題為真的,不見得一定可以被證明。"

[Wikipedia] Gödel's incompleteness theorems
two theorems of mathematical logic that state inherent limitations of all but the most trivial axiomatic systems for arithmetic. They state that any effectively generated formal theory in which all arithmetic truths can be proved is inconsistent; hence, any such consistent formal theory that can prove some arithmetic truths cannot prove all arithmetic truths." - 二十世紀最重要的數學定理,影響力橫跨科學與人文,直指人類心靈的內在運作。

[Wikipedia] Reductionism
化約主義 "A)an approach to understanding the nature of complex things by reducing them to the interactions of their parts, or to simpler or more fundamental things B)a philosophical position that a complex system is nothing but the sum of its parts... A contrast to the reductionist approach is holism or emergentism. Holism recognizes the idea that things can have properties as a whole that are not explainable from the sum of their parts (emergent properties).
