Title: Time
1Time
- Is there a clock anywhere?
2Yesterday is but a memory Tomorrow is but a
dream Today is the reality
3As you read this sentence, from start to finish,
you may or may not recognize the flow of
time. Did time really flow, or was that just an
illusion?
4Is the future open and changeable, until it
becomes the present?
5Is the past really fixed?
6J.R.R. Tolkien said that there were different
levels of reality. One level of reality is that
of a past which really did happen, even though it
may or may not be known.
7J.R.R. Tolkien said that there were different
levels of reality. One level of reality is that
of a past which really did happen, even though it
may or may not be known. Another (second) level
of reality is that which is known (or believed)
by everyone, even though conflicts with the first
level of reality.

the second level of reality was the only one
that had validity.
9Albert Einsteins theories of relativity suggest
that there is no one single piece of time, and
that all moments are equally real.
10Is time fundamentally real? An analogy is
thisis a chair fundamentally real?

acts real. Is is made of Wood and leather, which

is his glamour shot.
19- Make time, or get rid of it.
- Sir Issac Newton had three great laws
- Things like to keep doing, what they are already
doing, in straight line.
20- Make time, or get rid of it.
- Sir Issac Newton had three great laws
- Things like to keep doing, what they are already
doing, in straight line. - Force equals Mass times Acceleration
21- Make time, or get rid of it.
- Sir Issac Newton had three great laws
- Things like to keep doing, what they are already
doing, in straight line. - Force equals Mass times Acceleration
- Each action has an equal and opposite reaction
22- Make time, or get rid of it.
- Sir Issac Newton had three great laws
- Things like to keep doing, what they are already
doing, in straight line. - Force equals Mass times Acceleration
- Each action has an equal and opposite reaction
- With thiseveryone had to agree that there was a
sequence of events - Example with the equation force mass x
acceleration. - An object is given a mass of 10 kg.
- The object is given a velocity (say zero)
- A force is applied
- The object accelerates
- There is a flow to the sequence of events. Time
gives it an order. - The object cannot accelerate BEFORE the force is
applied
23Time must also have an idea, or a notion, or
duration. An example is that Tony and Tina both
left home for 3 hours. In order for them to
meet back at the same time, an hour has to mean
the same thing to both of them. An example is
that Tyson is going to eat 25 chicken wings in
one hour. Time has to endure for an hour to find
his wing eating rate. In order to find the rate,
time has to endure, even though it is in the past.
24Newton said (but not in so many words), that the
world exists within the confines of an enormous
clock, and everybody works within that
clock. That clock said, if Newton is correct,
that time a. Has order
25- Newton said (but not in so many words), that the
world exists within the confines of an enormous
clock, and everybody works within that clock. - That clock said, if Newton is correct, that
time - Has order
- Has continuity
26- Newton said (but not in so many words), that the
world exists within the confines of an enormous
clock, and everybody works within that clock. - That clock said, if Newton is correct, that
time - Has order
- Has continuity
- Has duration
27- Newton said (but not in so many words), that the

time - Has order
- Has continuity
- Has duration
- Has simultaneity

time - Has order
- Has continuity
- Has duration
- Has simultaneity
- Has flow
- Has duration
- Taken as a whole, this is
- called time.
30Assaults on the castle time. Ludwig Boltzmann
(an Austrian) reasoned, and proved, that Newtons
equations worked equally well going forward or
backward in time, so time must not have a built
in arrow.
31- Assaults on the castle time.
- Einstein showed, in his special theory of
relativity, that - What two people are doing at the same time
depends upon the speed at which they are moving. - Events dont happen in a place or at a certain
time, but they happen in a union of space and
time, called spacetime.
32- Assaults on the castle time.
- Einstein showed, in his general theory of
relativity that . - If the theory of special relativity, and
spacetime put a heavy load on the idea of a
master clock, called time, then the theory of
general relativity crushed it. - The introduction of gravity as a distortion tool
for time makes it impossible for any two clocks
to be synchronized, even if they started out that
way.
33- A summary of time, according to Einstien, would
say that either - There are no clocks in the universe
- or
- b. There are many clocks, and each works with
only a very small part of the Universe, or to a
particular object.
34- Quantum Time
- Quantum Mechanics says that, there are
probablilities of different outcomes. - Time is that thing that makes the contradictions
of probabilities happen. - A rolled dice cannot have both the 3 and the 6
showing. - Changes in quantum fluctions must be chromatic.
- Quantum mechanics provides for quantum
probabilities and possibilities for all of space
at the same time. - Entanglement implies spooky action at a
distance, and is dependent upon a master
universal clock. - This is why Einstien hated, hated, hated quantum
mechanics
35- Quantum mechanics, which is
- Tested
- Proven
- Gives unerringly correct results
- The basis for computers, light science and
statistical experimentation - needs for the Universe to have a Master Clock
- General relativity, which is
- Tested
- Proven
- Gives unerringly correct results
- The basis for nuclear physics, astronomy
- expressly forbids a Master Clock
36Do we really need time? Time is a placekeepper,
like dollar bills. Our class will let out in 375
heartbeats. Light travels 240,000,000 meters per
beat
37- Schrodingers Cat
- If we get rid of time, it can be
- Dead with respect to itself
- Alive with respect to the person in the room
- Dead with respect to another person in the
hallway - The situation (life and death) of the cat is
never resolved.
