Einstein’s Special Theory of Relativity

• “Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore.”

Albert Einstein

Dramatic Space and Time

• Einstein’s Special Theory of Relativity

• The Relationship Between Relativity and the Dramatic Experience

• The Dramatic e = mc2


• Einstein’s Special Theory of Relativity

• The Relationship Between Relativity and the Dramatic Experience

• The Dramatic e = mc2


• If you are moving away from a clock and look back at it, the light you see must catch up with you. If your motion is near the speed of light, the clock you see will be slow.

• A clue to the flexibility of time itself.

Understanding Relativity

• The speed of an object varies with the speed of the train. The train above is travelling at 30 mph, and the man on the train throws the ball in the direction of the train’s travel at 20 mph.

• To the man on the ground, the ball is travelling at 50 miles per hour.


• However, to the man on the train, the ball is only travelling at 20 miles per hour.!


• No matter how fast the above train travels, the light from the man’s flashlight will still travel at 300,000 km/sec!

• For both the observer, and the man on the train, the light travels at 300,000 km per second!

• The speed of light is constant!

• If velocity = distance/time, and both the distance the light travels, and the velocity of the light are the same for both observers, then time must be different for each observer!

• "The relativistic analogy can be carried to its logical end. Since time begins to slow down with higher speeds, it can be shown that at the speed of light it stops totally and beyond that begins to run backwards! Similarly, matter having contracted more and more, ultimately vanishes. But beyond the speed of light it is difficult to imagine negative matter with infinite mass."

-Albert Einstein

Einstein’s Special Theoryof Relativity


• As c approaches 300,000 km/sec, time slows down.

• If c = 300,000 km/sec, time stops

• If c > 300,000 km/sec, time goes backward

• We could travel forward in time!

• Spaceship travel close to the speed of light would cause time to s-l-o-w d-o-w-n .

The Relationship Between Physical Space/Time and Dramatic Space/Time

But isn’t this exactly what happens in the dramatic experience?

Antony and Cleopatra:28 spaces in three days!


=

?• Inside it feels like we are not moving, and time is progressing

normally• We are aware of another world where time and space are

compressed


c = d/tOr, if c is constant,

time = d/c!

“c” is a very important part of the

dramatic experience!

The Frame of Reference for a Theatre Audience

Frame of reference:

1: an arbitrary set of axes to which the position or motion of something is described or physical laws are formulated

2: a set or system (as of facts or ideas) serving to orient or give particular meaning”

• The theatre building, audience, seats, other audience members, etc.

• Time passes normally according to a watch

• The dramatic setting of the play

• Time passes according to a set of dramatic rules

PhysicalSpace and Time

DramaticSpace and Time

The transition from the Physical space/time to the Dramatic space/time is accomplished in the

Exposition of the play!


• Space is determined by physical scenery

• Time is relative to an outside reference (clock)

• Space and time are relative to each individual

PhysicalSpace and Time

DramaticSpace and Time

Notice how dramatic time conforms more closely to Einstein’s understanding of relativity


• "Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity.”

-Albert Einstein

ct1


• It is a constant similar to the speed of light or the speed of electromagnetism

• Since it is constant in the formulac=d/t

we can freely manipulate distance and time in the dramatic frame of reference!

• Next: transforming physical mass using “c”...

• “c” is the speed of dramatic imagination

The Dramatic e=mc2

• "It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -- a somewhat unfamilar conception for the average mind. Furthermore, the equation E is equal to m c-squared, in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned before. This was demonstrated by Cockcroft and Walton in 1932, experimentally."

• Energyis equal to

• Massmultiplied by the ratio of

• Distanceto

• Time

The Dramatic e=mc2

• 1: vitality of expresssion

• 2: the capacity of acting

• 3: power forcefully exerted

• 4: the capacity for doing work

Energy:

Energy: the life-force of the drama, or the vitality of dramatic expression

The Dramatic e=mc2

• “1: a complex structure of interdependent and subordinate elements whose relations and properties are largely determined by their function in the whole;

• 2: an individual constituted to carry on the activities of life by means of organs separate in function but mutually dependent.”

Organism:

Energy: the organism or life force of the drama; the vitality of dramatic expression

The Dramatic e=mc2

• “the property of a body that is a measure of its inertia, that is commonly taken as a measure of the amount of material it contains, that causes a body to have weight in a gravitational field, and that along with length and time constitutes one of the fundamental quantities on which all physical measurements are based”

Mass:

Mass: the physical entity of the drama: the inert actors, scenery and costumes

The Dramatic e=mc2

• “Quickness of motion”

• v = d/twherev = velocityd = distancet = time

VelocityThe Dramatic e=mc2

Space:

• “1. a period of time

• 2. a limited extent in one, two, or three dimensions: Distance, area, volume.”

Distance:

Distance is a measure of space.

• “a separation in time.”

The Dramatic e=mc2

• “1: the measured or measurable period during which an action, process, or condition exists or continues”

• 7a: rate of speed: TEMPO b: the grouping of the beats of music: RHYTHM ”

Time:

The Dramatic e=mc2

• “c” is the ratio of two very similar, but complementary quantities, space and time.

• “c” is the factor responsible for placing the dramatic mass in motion;

• “c” is squared in the formula e=mc2 because it has an exponential influence on the creation of the life force energy of the play.

• “c” reveals mass through light and sound, as perceived by the eyes and ears;

Velocity

Velocity: The ratio of space to time (d/t); the space time continuum; transmitted by sound and light, and perceived by the ears and eyes

The Dramatic e=mc2

• Dramatic mass put into motion by space and time creates the life-force or energy of the play.

Light and Sound, Space and Time

• The speed of light is a constant:300,000 km per second

• Note that the speed of light is always measured and defined relative to the observer (e.g., a time reference)

• It remains constant for all observers, regardless of the relative velocities of the observers.

Source: http://csgrad.cs.vt.edu/~chin/speed.html

The speed of sound, however, is dependent on the space that conveys it. The speed of sound varies depending on the medium that conveys it.



Light-particles accelerated, on the other hand becomes mass. Light, then, must be unequivocally anchored in space.

• whereas,• The speed of sound is measured and defined relative to

the space that conveys it (i.e., a spatial reference).

• Note that the speed of light is always measured and defined relative to the observer (i.e., a time reference);



• Light reveals space by defining it relative to time

• Sound reveals time by defining it relative to space

Reconciling Dramatic Space/Time with Physical Space/Time

• …is very difficult to do! • Aristotle proposed limiting dramatic space/time

through the unities of time, place, and action• Continued in mid 18th Century neo-classicism,

and in the development of the “box set” and rise of Realism

• All dramatic ideas do not conform so well to a drama of limited time, place and action!


• Periaktoi (Sophocles) • House-platea staging and pageant wagons of medieval

drama• Perspective scenery of the16th and 17th century theatre• Stage machinery of the 18th century• Lighting in the 19th century• Modern theatre (with its fly system, traps, wagons,

projections, etc.)

• The history of theatre is one of different attempts at reconciliation:


• Shakespeare “required a fluid stage where space and time changed freely and quickly.”

• Limited the physical space time (e.g., scenery, costumes, etc) requirements.

• Late 19th and early 20th century designers such as Appia, Craig, and Meyerhold developed innovative solutions to free the physical space/time in support of a fluent dramatic space/time.


• The development of Film

• Film allows space and time to change as quickly as the dramatist requires.

• Film is chiefly limited to two dimensions, however!


• 20th-21st century explorations of time in the visual arts

• The development of the music-video of the MTV generation

• The development of the film editor as “visual percussionist”


• 20th-21st Century explorations of space in the sonic arts

• Monaural sound, stereo, 5.1. 7.1, 9.1, 10.2.• It would “take about 1,000,000 channels to fully

capture one space and reproduce it in another in all its detail…”

• The audio pixel: a regular array of transducers on a two-dimensional grid…(of) hundreds or thousands of transducers

Conclusion

• "Relativity teaches us the connection between the different descriptions of one and the same reality.”
