The Walls of Jericho - Could They Have Fallen as the Bible Describes?

The Battle of Jericho is one of the more astonishing stories in the Bible. Some guys march

around a city, tootle their horns, the walls fall, and they storm in. Of course, scientific thinking

proves that story is totally implausible ... or does it?

Breaking the Wall s Joshua 6:3-5

You and your fighting menshould march around the town

once a day for six days.Seven priests will walk

ahead of the Ark,

each carrying a ram's horn.

On the seventh day you are

to march around the townseven times, with the priests

blowing the horns. When youhear the priests give one

long blast on the rams' horns,have all the people shout

as loud as they can.

Then the walls of thetown will collapse.

How Did the Jericho Walls Fall Down?

According to Joshua 6:2-5, the three simple instructions given to the Israelites were:

1. March around the city once a day for six days.

2. March around the city seven times on the seventh day.

3. After the marches are complete, the priests blast their horns and all the people shout together.

We know quite a bit today about scientific principles unknown at the time of the Israelites'

attack on Jericho. Specifically, the Jericho story references the principle ofresonance:

mechanical resonance and acoustic resonance, the two forces that collapsed thewalls of Jericho.

Mechanical Resonance

What Is Mechanical Resonance?

This is the simplest possible explanation I could find for mechanical resonance.

Every object has a unique natural frequency of vibration.

A periodic force occurring at the same frequency as the natural frequency of vibration of

an object may cause the object to vibrate. This is called mechanical resonance.

The force and the object being affected must come into physical contact for mechanicalresonance to occur.

Mechanical resonance may cause objects to fail.

In certain applications, parti cularl y in civil and mechanical engineering, anunderstanding of mechanical resonance is essential to prevent the failure of materials.

from Saskatchewan Education

Basically, when two objects that are touching each other vibrate

together, the resul t can be increased vibrations or decreased

vibrations, depending on the frequency at which each object is

vibrating. Vibrations can increase to the point of destroying theobjects vibrating.

Bridges Fail Because of Mechanical Resonance

Marching armies break lockstep on bridges so the bridge won't break.

The Angers Bridge in Angers, France, collapsed on 18 April 1850 when 478 Frenchsoldiers marched across in lockstep; 226 soldiers died in the river below. "Because the soldiers

were marching together, they caused the bridge to vibrate and twist from side to side, dislodging

an anchoring cable from its concrete mooring."[read more]

The Tacoma Narrows Bridge in Tacoma, Washington, collapsed in 1940. This is

commonly attributed to mechanical resonancebut is now known to have been due to

aeroelastic flutter, unrelated to any sort of resonance.

The Manhattan Bridge reacted dynamically to two recent mass pedestrian exoduses from

the island. The cables groaned and the bridge swayed visibly from side to side as masses of

pedestrians crossed the bridge after 9-11 and again during the blackout of 2003.

"Contrary to logic, pedestrian traffic is actually heavier than vehicular traffic. Pack people

into the same square footage of a car or SUV, and the humans weigh more than the

vehicle. What's more, pedestrian movement interacts with a bridge - vibrating it, inthe words of several engineers - in a much more chaotic and little understood way. While

cars and trucks move their weight in a smooth, uniform manner, pedestrians constantlyshift weight from side to side and strike the bridge in an up-and-down motion. Witnesses

observed the bridge reacting to both types of pedestrian stress on the day of the

blackout.

"Allan McRobie, a lecturer in engineering at Cambridge, says flatly that bridges are not

designed for the dynamics of crowd interaction. He called pedestrian traffic and bridgeengineering "a gray area" where a complex web of action and reaction is at work. "The

basic point is that engineers don't know what happens when a crowd walks over abridge,"he says.

"Ochsendorf of M.I.T. says he wondered about the bridge's load and reaction when he

watched the blackout coverage on television. For a decade, engineers have learned howfoot traffic vibrates a bridge. "The problem of lateral vibration has been noted for more

than a century, but no one has become concerned about it as a design problem until thelast couple of years." "

An Earthquake Machine

Nikola Tesla claimed to have built an earthquake-producing machine.

Nikola Tesla established a laboratory in New York. While experimenting with

mechanical oscillators, he allegedly generated a resonance of several buildings

causing complaints to the police. As the speed grew he hit the resonance frequency of hisown building and belatedly realizing the dangerhe was forced to apply a sledgehammer to terminate the experiment, just as the astonished police arrived.

The Discovery Channel's popular MythBusters show examined Tesla's claim that he had

created an "Earthquake Machine" in their 60th episode. They tested the physicalphenomenon known as mechanical resonance on a traffic bridge, which today are built to

withstand such forces. While a single I-beam of steel was deflected several feet in each

direction by their oscillator, and they reportedly felt the bridge shaking many yardsaway, there were no "earth shattering"effects. It is worth indicating that, in the time of

the event undertaken by Tesla, buildings were not built to withstand such resonance.

MythBusters: PLAUSIBLE

Will lockstep marching break a bridge?

There were some difficulties in testing this myth conclusively. During the first test, Jamie made

12 air-powered marching soldiers, but they moved too slowly. During the second and third tests,

the soldiers stomped too hard on the bridge, causing the bridge to collapse without any harmonic

vibration.

When this myth was revisited, it was proven plausible.

Acoustic Resonance

Acoustic Resonance Shatters GlassAcoustic resonance is more familiar to most of us than mechanical resonance. We've all at least heard of

sound shattering glass, even if we've never seen it in action. Here is a nice, simple-to-understand

explanation of how acoustic resonance makes music on glass rims, and the same principle can shatter

glass.

Glass Shattering in Slow Motion

This is SO cool! You can see the glass vibrating before it shatters!

Yes, Voices Can Shatter Glass Too!

And here is a little more dynamic demonstration of the principle that sound from the throat can shatter

solid matter!

The Walls Collapse Joshua 6:20

When the trumpets sounded,

the people shou ted,

and at the sound of the trumpet,

when the people gave a loud shout,

the wall collapsed;

so every man charged straigh t in,

and they took the city.

So What Broke Down the Walls of Jericho?

Could it have been mechanical and acoustic resonance?

Consider the story as outlined in the book of Joshua:

Thousands of men marching lockstep six times, over a space of six days, around a

city wall constructed of baked mud: mechanical resonance.

Thousands of men marching lockstep around the same walls seven times in a single

day: mechanical resonance.

A unified blast from the ram's horns as thousands of men raise their voices and yell

in unison: a shattering blast of acoustic resonance to walls weakened over a week's

worth of mechanical resonance.

Notice too that every man charged straight in- which means that they didn't batter downa section of the wall, but allthe walls shattered at once - like a glass shattering underacoustic resonance, so that everyone in the long line had access to the city immediately.

Joshua Fit the Battle of Jericho

by Golden Gate Quartet (yes, it's "fit")

Was I t a Miracle?

M ir acles are not contrary

to nature, but only contrary

to what we know about nature.

~ St. Augustine

So Did It Happen, or Not?

Could the walls of Jericho have collapsed as the Bible describes?

I don't really expect this little lens to convert anyone to my way of thinking. But I'd be

happy if you would just take this away with you: a document universally agreed to bethousands of years old (whether it is believed to be true is another matter, but even

naysayers agree that it is very, very old) has just described a perfect application and effectof an instance of mechanical and acoustic resonance; perhaps not in scientific terms but

certainly accurately enough to be recognizable.

How ever on earth could anyone from that era have known to make up a story using

just those circumstances, if it were not true?

So Was It a Miracle, or Not?

If the Jericho walls collapsed due to resonance, was it still a miracle?

I do not believe there is any conflict between science and the Bible. I know there are

true believers on both sides of that statement who will disagree with me violently! I standwith St. Augustine: "Miracles are not contrary to nature, but onl y contrary to what we

know about nature."God created nature and the laws of nature. Science is the study ofnature; therefore science is the study of how God did what He did, and not being

afraid of what is uncovered. Remember, the medieval church was afraid of Galileo'sscientific discovery that the earth revolved around the sun and thought it would break

people's faith. My God weathered that storm as He will weather many more.

So does understanding the principles of mechanical and acoustic resonance make the fallof Jericho somehow less of a miracle? Far from it - in fact, the reverse in my mind. Yes, it

is a miracle that a guiding principle of the universe may have been built around

accommodating this single week of history!

This is not so much saying that God has to, or does, work within the laws of nature, as it

is saying that the laws work around what H e wants to happen. In other words, what Godwants to happen ARE the laws of the universe. Think about it: if God created the universe

with Legos, He doesn't have to stick a Tinkertoy in somewhere to make happen exactlywhat He wants to have happen. God doesn't need to - nor does He - break His own

laws.

God does not play dice with the universe.
