spent light

Louis Kahn is transfixed by light: “The sun never knew how great it was until it struck the side of a building.”

To Kahn not only is light the principal descriptor of architecture, but all matter (the material of architecture itself) is spent light.

E = mc2

(E² = m² * c⁴ + p² * c²⁾
where E is energy, m is mass, and c is the speed of light in a vacuum. The formula is dimensionally consistent and does not depend on any specific system of measurement units. For example, in many systems of natural units, the speed (scalar) of light is set equal to 1, and the formula becomes the identity E = m; hence the term "mass–energy equivalence".[2] The equation E = mc2 indicates that energy always exhibits relativistic mass in whatever form the energy takes.[3]

Big Bang

According to the most recent measurements and observations, this original state existed approximately 13.7 billion years ago,[2][3] which is considered the age of the Universe and the time the Big Bang occurred.[4][5] After its initial expansion from a singularity, the Universe cooled sufficiently to allow energy to be converted into various subatomic particles. It would take thousands of years for some of these particles (protons, neutrons, and electrons) to combine and form atoms, the building blocks of matter.http://en.wikipedia.org/wiki/Big_Bang

Little Boy
Approximately 600 to 860 milligrams of matter in the bomb was converted into the active energy of heat and radiation (see mass-energy equivalence for detail). It exploded with an energy between 13 and 18 kilotons of TNT (54 and 75 TJ) (estimates vary).
