[i] “… the body of the Archduke of Austria…”
“Franz Ferdinand (December 18, 1863 – June 28, 1914) was an Archduke of Austria-Este, Prince Imperial of Austria and Prince Royal of Hungary and Bohemia, and from 1896 until his
death, heir presumptive to the Austro-Hungarian throne. His assassination in Sarajevo precipitated the Austrian declaration of war. This caused countries allied with Austria-Hungary
(the Central Powers) and countries allied with Serbia (the Entente Powers) to declare war on each other, starting World War I.
In 1889, Franz Ferdinand’s life changed dramatically. His cousin Crown Prince Rudolf committed suicide at his hunting lodge in Mayerling, leaving Franz Ferdinand’s father, Archduke
Karl Ludwig, as first in line to the throne. However his father renounced his succession rights a few days after the Crown Prince’s death. Henceforth, Franz Ferdinand was groomed to succeed.
On June 28, 1914, at approximately 11:15 am, Franz Ferdinand and his wife were killed in Sarajevo, the capital of the Austro-Hungarian province of Bosnia and Herzegovina, by Gavrilo Princip, a member of Young Bosnia and one of several (a few) assassins organized by The Black Hand (Црна рука/Tsrna Ruka). The event, known as the Assassination in Sarajevo, triggered World War I.
Franz and Sophie had previously been attacked when a bomb was thrown at their car. It missed them, but many civilians were injured. Franz and Sophie both insisted on going to see all those injured at the hospital. As a result of this, Princip saw them and shot Sophie in the abdomen. Franz was shot in the jugular and was still alive when witnesses arrived to his aid, but it was too late; he died within minutes.
The assassinations, along with the arms race, nationalism, imperialism, militarism, and the alliance system all contributed to the beginning of World War I, which began less than two months after Franz Ferdinand’s death, with Austria-Hungary’s declaration of war against Serbia.”

[ii] …”force field”…
“Originally a term coined by Michael Faraday to provide an intuitive paradigm, but theoretical construct, for the behavior of electromagnetic fields, the term force field refers to the lines of force one object (the “source object”) exerts on another object or a collection of other objects. An object might be a mass particle or an electric or magnetic charge, for example. The lines do not have to be straight, in the Euclidean geometry case, but may be curved. Faraday called these theoretical connections between objects lines of force because the objects are most directly connected to the source object along this line.
Examples of force fields:
- A local Newtonian gravitational field near Earth ground typically consists of a uniform array of vectors pointing in one direction—downwards, towards the ground; its force field is represented by the Cartesian vector , where points in a direction away from the ground, and m refers to the mass, and g refers to the acceleration due to gravity.
- A global Gravitational field consists of a spherical array of vectors pointing towards the center of gravity. Its classical force field, in spherical coordinates, is represented by the vector, , which is just Newton’s Law of Gravity, with the radial unit vector pointing towards the origin of the sphere (center of the Earth).
- A conservative Electric field has an electric charge (or a smeared plum pudding of electric charges) as its source object. In the case of the point charges, the force field is represented by , where is the position vector that represents the straightest line between the source charge and the other charge.
- A static Magnetic field has a magnetic charge (a magnetic monopole or a charge distribution).
- The electromagnetic force is given by the Lorentz force formula, which in SI units is.”
