      BACK to PLATO's CAVE: A HERMES/URANIA JOINT - Part One

                      PLANES, TRAINS and AUTOMOBILES

                    MOMUS APPROVED/ALETHEIA BLESSED

    by Richard DePersio and Aphrodite/Citizen Journalist Janus Calliope

          (the first DePersio with the late 'Wolfman'* Collaboration;

              let's hope that it is a Harbinger of Things to Come**)

 

(Part Two follows...Part One will continue in Part Three). 

In part two, RD inadvertently offends Zeus; here, in part one, he

further apologies. Is time in reverse!?! There's a FOX NEWS ALERT

concerning it at www.rickcmtsite.blogspot.com 

RD: I got it! Saturn's (in Greek Mythology: Kronos --- BOO!!!; that should

please Zeus) Shepard's: Type One - moons outside of the ring system 

whose perturbations cause gaps in the rings - Daphnis is responsible for

 the Keeler Gap and our friend Pan (www.pan-multiverse.blogspot.com )

claims credit for the Encke Gap, both in the 'A' Ring; Type two - moons

near edge of a ring causes them to enjoy sharp, crisp/more definition

edges -- Promethesus' post is the inner while Ponderous (the first

human female created by Zeus) handles the outer 'F' Ring and it was

thought that Atlas*** was given boss duties regarding 'A' ring but it turns

out the that our buddy Janus and Epimetheus have that honor and power.

 (Atlas disgraced. HOORAY! That should please the King of the Gods

(capital 'G').

(RD: "When in high school, I was in college-level program at a planetarium

and was assigned a project regarding the Gaps (not jeans). This  section

afforded me the opportunity to brag! Never a slave to fashion: never wore

 jeans or dungarees. Boasting again!).

 

What does it have to do with Al's Relativity!?!

Wind Drift: What happens if there is wind blowing against your airplane?

 "Nothing works out as it ought to work out. In crosswind flight---does

the air press harder against the airplane's windward side than against its

leeward side?" When it comes to flight --- leave common sense on the

ground! A pilot would say: It is futile to try to counteract drift!!!

      "It helplessly participates in the motion of that air mass, it 'drifts'

with the wind." When force isn't force. The plane is moving because the

wind is pushing it. "The wind can't blow against the airplane because

the airplane doesn't present itself to be blown at; it yields without any

resistance: it moves with the air. A pure example of this kind of motion,

drift, is the travel of the free balloon. Here is one kind of aircraft that has

no motion at all through the air (other than perhaps climb or descent)

but moves only with the air. The free balloon has no 'air speed,' no

relative wind'. To its pilots, it always seems to be flying in a complete

dead calm. Even though it may be flying in a gale and drifting across the

country at 50 m.p.h., there still won't be even the gentlest breeze in the

basket. This is because it yields so completely to the motion of the air,

and it participates in it: the balloon does not push against the air, and

neither does the air push against the balloon; hence no forces arise."

WHAT!!! The wind can't exert a force on the balloon by virtue of the

fact that the balloon is drifting; drifting nullifies all wind forces on it. If

you blow against a ball, the ball moves as you placed a force in it. On the

other hand, if the air around the ball moves and the ball moves with it -

no force has been exerted on the balloon. No force; total surrender (or

yield. Still not convinced?

      You're no longer in an airplane or a balloon. Now, you're safely on

the ground, well, in a railroad car. You walking in the railroad car is

just like an airplane flying in a wind. Think in terms of steady motion:

you are moving at the same speed and in the same direction. You

wouldn't be able to tell if you were moving or standing still (for our

thought experiment (Al loved to think and explain by TE; we will ignore

 jolting and bouncing due to roughness of track).

      You find that you can walk forward or backwards or sideways with

ease; if you don't look outside you couldn't tell in which direction that

the train is moving. Draw the blinds. If the track were smooth, you

would wonder if you are moving or standing still. You don't even have

to struggle to balance if you move "cross-train," left to right in the car.

The motion of the train doesn't concern you.

      "When a pilot flies in a wind, the wind is his railroad coach, but we

shall see about that later."

      There is your motion relative to the train and the motion of the train

to the rest of the USA outside --- of course, you being carried by train

at say 75 m.p.h. You walk to the dining car, eat and return to your seat

and say, "I'm back where I started from" (we apologize, dear readers for

ending a sentence with a preposition. as regards, female readers,

no apology, consider it a strange proposition!). In one sense, you would

be right and in another wrong. The seat to which you have returned has

in the meantime moved something like 50 miles. It's a paradox. Whether

or not you are truly back to where you started from "depends, in highbrow

words" on your "frame of reference," that is which side of the facts {you}

choose to regard, and which side {you} choose to disregard; whether

{you} judge your position by reference to the train, or by reference to the

United States outside.

     "...an airplane that flies in moving air is like {you} who walks within a

moving train. Just as {you are} "contained" by the railroad coach {car}

and cut off from the scenery outside, so is the airplane, once in flight,

entirely "contained" by the surrounding air and cut off with all connection

with the ground. Its propeller {or engine} propels it, not by acting on the

ground, but by acting on the surrounding air. Its wings hold it up, not by

acting on the ground, but by acting on the surrounding air. Thus the

cubic mile or so of air in which the airplane {or jet} flies is to it exactly

what the railroad coach is to the train passenger {you}. The only

difference is that the railroad coach surrounds  {you} visibly, while the

air surrounds the airplane invisibly."

     Hence, whatever is true of you when you walk within a moving train

"is equally true of an airplane that flies within a mass of air which is

itself in motion. The airplane, too, has two motions, both at the same

time. It has a motion though the air, which corresponds to {you} walking

through the train. It has a motion with the air, called drift, which corresponds

to the travel of the train." A pilot can focus his attention on one motion

or the other and, with time, can hold both in mind simultaneously and not

experience confusion.

     "Look first at his motion through the air: in a sense this is the all-

important motion, since it is what makes the air strike his wing and

produce lift; what makes the air strike the tail surfaces and gives him

stability and control. And incidentally, it is the motion that registers on the

air-speed indicator."

    "This motion of the airplane through the air is in no way affected by the

fact that the air itself is in motion---any more than {you} walking within the

train is affected by the travel of the train." You walk in train in all directions

and experience no need for special balancing and no sensations. "In the

same way, the airplane can not 'feel' any difference between down-wind

and up-wind flight and cross-wind flight. It feels the same; the engine has

to pull no harder; the air-speed indicator indicates the same; the lift is

the same."

    You can draw the blinds and not know which way train is moving. Pilot

can draw the blinds --- not look at ground or get above a solid overcast.

The pilot would not know if he were flying in a gale or a calm. "In short,

the wind does not have any effect on air speed, lift, stability, and control:

an airplane, once in flight, can not 'feel' the wind.

    No matter what you do within train - you helplessly participate in its

motion; regardless of pilots maneuvers, he helplessly participates in the

motion of the air mass; it 'drifts' with the wind. It is helpless like the

free balloon discussed way back a the beginning; there is no force on

plane by wind because plane is completely yielding.

    Flying a Heading: direction on compass; Flying a Track: direction that

you are moving over the ground; Flying a Course: It is the intended path.

    Student pilot looks at ground and sees plane veering eastward and

wants to take action to 'counteract drift' by use of rudder. This is

a waste of time and could change your heading. Is the situation

hopeless; are we victims of DRIFT!  Nay! A trick can save the day.

"Nothing in the world will keep an airplane sliding eastward as long as

it is flowing in westward flowing air {crosswind)" Does it mean that a

plane can never reach its destination!?! "...you can outfox this effect,

and the experienced pilot does so automatically. Upon noticing the

eastward drift, he points his airplane slightly west of north...when the

eastward motion with the air adds itself to this northwesterly motion

through the air, the resulting motion over the ground will be exactly

north."

    Let's take it further...You're in a spacecraft with no windows. Is it

moving at a constant speed or accelerating at the same rate and

moving in the same direction --- or is craft sitting on the earth?

    CJ enters cars, sits and says, "I'm out of here - for now. To be

continued at Part Four...Part Two follows."

 Without explicitly saying so, the Wolf taught some Albert Relativity.
