Before writing was invented, cities in the Indus valley and in Sumer (present Iraq) had developed sophisticated masonry. The Sumerians built tall buildings seven stories high with baked clay bricks (circa 4,000 BC). They were the Biblical builders of the ill-fated tower of Babel, also built with masonry, which was a city situated 20 miles south of present-day Baghdad. Further development of masonry were brought forth by the Babylonians, Egyptians and ancient Chinese. Many of their structures are still standing.
When can a d-dimensional rectangular box R be tiled by translates of two given
d-dimensional rectangular bricks B1 and B2? We prove that R can be tiled by
translates of B1 and B2 if and only if R can be partitioned by a hyperplane into
two sub-boxes R1 and R2 such that Ri can be tiled by translates of the brick Bi
alone (i = 1, 2). Thus an obvious sufficient condition for a tiling is also a necessary
condition. (However, there may be tilings that do not give rise to a bipartition of
Khối xây gạch đá (Brick or stone masonry) là tập hợp của những viên gạch đá riêng lẻ, được gắn chặt với nhau bằng vữa xây và được xếp thành hàng, thành lớp, nhưng toàn bộ tập hợp đó phải chịu lực (thường là các lực nén ép) như một thể thống nhất mà không có sự dịch chuyển của mọi viên thành phần. Vật liệu thành phần làm nên khối xây thường là những vật liệu ròn, chịu ứng suất nén rất tốt hơn rất nhiều chịu ứng suất kéo.
Do you know what Accounting Noise is? How about Illiquid? Bricks and Clicks? Any idea what GAAP, LBO, RFP, or SOW stand for? Let's face it: You can't survive the corporate jungle today unless you speak the language.
It's time to learn!
As mentioned before in my previous book, "Modern Kung Fu Karate", that the Brick Breaking and Iron Hand Training is not a necessary parat of Gung Fu training - this book deals strictly with self defense.

Old brick buildings, cobblestone streets, countless churches with clanging bells — charming Cremona in the northern Italian province of Lombardia is a town brimming with medieval relics. While small enough for ambling sightseers to explore in a single day, Cremona is world-renowned as the birthplace of Stradivarius and other master violinmakers. Even now, it is home to nearly 100 stringed instrument makers’ ateliers.
The preparation of this British Standard was entrusted by the Civil Engineering and Building Structures Standards Committee (CSB/-) to Technical Committee CSB/31, upon which the following bodies were represented: Association of Building Component Manufacturers Ltd. Brick Development Association British Precast Concrete Federation Ltd.
The unwritten record of history is preserved in buildings—in temples,
fortresses, sanctuaries, and cities constructed of brick and stone. Early
efforts to build permanent shelter were limited to the materials at hand. The
trees of a primeval forest, the clay and mud of a river valley, the rocks, caves,
and cliffs of a mountain range afforded only primitive opportunity for protec-
tion, security, and defense and few examples survive. But the stone and brick
of skeletal architectural remains date as far back as the temples of Ur built
in 3000 B.C.
The increased online presence of customers is making it imperative for traditional brick-and-mortar banks to establish themselves in the virtual space. Banks are moving toward virtualization by offering services on the internet and by mobile phone. The challenge today is to offer integrated financial services to customers across all delivery channels, introduce differentiated products to respond to and exceed customer expectations, and improve return on investment in a highly mature and competitive landscape.
Fair warning: This book is meant to be dangerous. Provocative. Arresting.
Like a brick thrown through the plate-glass window of the
CEO’s office, the meeting room of the board of directors, or the
faculty club of the business school that hits you up all the time for
alumni contributions. I argue that today’s competitive environment for
the business leaders is sufficiently hazardous and uncertain that you are
better off thinking of it not as business but as war.

At the same time, high tech professionals often perceive work as a “serious game” (Strannegård & Friberg,
2001), and not drudgery: they involve in playful behaviors at work (Hunter, Jemielniak, & Postuła, 2010).
Software engineers often participate in non-paid, open collaboration production (Lakhani & Von Hippel, 2003).
Modes of collaboration established in virtual and high-tech communities are similarly transforming
workplace relations in the brick-and-mortar organizations (Benkler, 2006).
Housing of course means homes. To most people this is their most
treasured possession. It is not just bricks and mortar or a financial
investment; it is a vital part of their life. ‘You mould the building and the
building moulds you’ as Winston Churchill is said to have put it. Home
is crucial to everybody’s daily well-being. As such it is normally treated
with pride, and its character and contents are an extension of their per-
sonality. The creation of a home is not therefore just an intellectual
design exercise detached from the occupant. It should be their design.
