If they did,

No if about it, they do.

No, nothing like that is required to comply.

There is no requirement for that much glass.

You are welcome to have no glass at all if you want to go that route.
Inca walls. According to various luminaries, they were either machined or
cast from concrete:

We know they are done with stone.
http://en.wikipedia.org/wiki/Inca_architecture#Masonry_and_construction_methods

We even know how to do stone walls like that now.

Those aren't anything like luminaries, just complete and utter loons.

And even if they were concrete, and they aren't they
have clearly lasted for a lot longer than 1000 years fine.

Just because someone claims something, doesn't make it gospel.
You really should read the book (about $24).

No thanks, I know its just plain wrong.
His previous book is just as interesting, but I don't know about the
prices:
<http://www.alibris.com/They-Built-t.../13863111?matches=2&cm_sp=works*listing*title>
I paid about $15.

I wouldn't pay a cent for something that is so wrong.
As far as ground load, it would work.

And as far as the modern building and seismic codes
are concerned, there arent any of those if he did it there.
The problem is that to make his scheme work, there will need to
be caretaker, guard, and possibly a staff of maintenance workers.

No, none of that was necessary with the pyramids, those inca walls,
or hordes of other places that have last more than 1000 years fine.
You could fortify the structure, but the pyramids
are a good example of how that doesn't work.

And those inca walls show that you don't need anything like that.
Nobody would want to live in the Australian desert.

Try telling that to those who do. Don't be too
surprised when they just laugh in your face.

And you don't need anyone anyway.
Would you invest in a company, who's facilities
were located in the Australian desert?

Plenty have been doing that for more than a century now.

And he isnt talking about getting anyone
to invest in any company anyway.
I would see it as a handicap, rather
than a benefit or requirement.

Then you need to get out more and see whats
happened on that for more than a century now.

Incidentally, the Aus desert location has been tried before. See

There are in fact plenty still doing that.

Well, let's grind the numbers and see how close we come to meeting the
soil support capacity for a pyramid. I try for the biggest, Khufu's
pyramid, which is 756x756 ft at the base, and 481 ft high.

Volume of a pyramid = 1/3 area_of_base * height
V = 1/3 * 756 * 756 * 481
V = 91.6*10^6 cubic-ft.

Limestone is about 170 lbs/cubic-ft.
91.6*10^6 cubic-ft * 170 lbs/cubic-ft = 1.56*10^10 lbs

Ground loading = Weight / area_of_base = 1.56*10^10 / (756 * 756)
= 27,300 lbs/sq-ft

The average single story home weighs in at about 300 lbs/sq-ft
including the foundation but not the live load. Local code for my
clay soil area is 2,000 lbs/sq-ft maximum. I believe that on sand, it
can pass at up to 4,000 lbs/sq-ft max but I'm not sure.

The Khufu pyramid exceeds the ground loading code limit by a factor of
about 10 and will probably fail the plan check or get red tagged.

Easy enough to say, but not so easy to accomplish.

Its completely trivial to drill a hole in the stones and analyse
it chemically. Concrete is completely different to stone.

And we can see where they quarried the stone too and
check that whats left there is stone and not concrete too.
Do you have a photo of a modern wall built with similar
construction techniques and similar close fitting stones?

Irrelevant to whether they are stone or not.
I couldn't find any.

Because once we invented stone tools, there was no point
in doing walls using that very much more laborious process.
I wonder what went wrong here:
<http://aboutfacts.net/History/H70/Stock.xching/603596_11287651_IncaStoneWall.jpg>
Looks like an original Inca wall at the bottom,
and some kind of repair or reconstruction on top.

Or someone just decided to make it much higher later on.
As for the Egyptians using copper tools, there aren't
enough such tools found in museums to build a small
tomb, much less a major structure like a pyramid.

All that shows is that copper was too valuable to just discard.
If copper tools, which become dull very quickly, were used
to quarry the pyramid stones, they should be more abundant.

Or they just wore out.
Also, please find me one reference that actually believes
that copper chisels were used to quarry granite:
<https://www.google.com/#sclient=psy-ab&q=copper+tools+to+cut+stone>

Having fun thrashing that straw man ?

The Incas did those walls without any copper tools at all.
I went though the first 2 pages of hits and didn't find a single one
that even suggested that it was possible. Most suggest that they
used an abrasive (sand) with copper drill and saws. Yet when I
tracked down people who have actually tried to do something
more than a trivial attempt at grinding through stone, they all
showed that it didn't work too well.

It clearly worked fine for the Incas.
Also, I failed to find any YouTube videos showing how
expansion of water soaked wood wedges will split stone.

All that shows is that your searching 'skills' are woefully inadequate.
Cool. Got any photos of modern stone walls that fit
together like the Inca stone walls? I couldn't find any.

Because it's a much more laborious process than using
metal tools to do stone walls the way we do them now.
Well, that's true, but the opposite is also true. Just
because you claim I'm wrong, doesn't make it wrong.

I didn't just claim you are wrong, I proved that the claim
that those inca walls are concrete is just plain wrong.

There is no point in those very complicated shaped blocks
if they were concrete. There is when you have to start with
the existing fractures in the rock and grind the rocks back
to what will fit so beautifully together.
I try to provide some substantiation to my claims.

ALL you did is wave around some loon claiming something
that completely trivial to prove is just plain wrong.
You simply declare me to be wrong.

Everyone can see for themselves that that is a lie
with the post you are replying to right now alone.
How do you know if you haven't read it?

Because it makes absolutely no sense at all to do those very
complicated shapes that are seen in the Inca walls if you are
making them with concrete. It makes a lot of sense when you
realise that since they did not have any metal tools, that they
had to exploit the existing fractures in the rock the started with.
I spent quite a bit of time reading about things I disagree with,

It makes a lot more sense to read what those who have worked
out how the Incas did those walls have to say about how its done.
and about things I know little.

Everyone knows little about how the Incas did those walls at one time.
It's not enough to know everything about your position.
You should know something about the point of view
expressed by those with whom you disagree.

ALL we need to know is that stupid claim that those Inca walls
are concrete and the evidence that proves that they are not.
The Egyptian tombs were entered by looters and
treasure hunters long before they were 1000 years old.

Some of them were, plenty of them weren't.

And that didn't stop the pyramids continuing fine anyway.
Most of them worked on building the tombs, making it an inside job.

You don't know that.
Only Tutankhamen escaped the pillaging.

And they are ALL still standing fine with the later ones.
It took a while longer with the pyramids, mostly because the
original potential looters knew that there was nothing of value
inside. Entry required gunpowder and then modern tunneling
equipment to get around the hard granite barriers, via the
softer limestone blocks. Given sufficient incentive, nothing
is impervious to a determined looter or archaeologist.

And those Inca walls didn't need any guards or maintenance crew either.
The Inca walls did not have anything of value inside to protect.

So you don't have anything of value to protect in his cryo system either.
My guess(tm) is that after only 100 years, any sealed
structure will become an archaeological target.

That hasn't happened with hordes of stuff older than that.
Certainly by 1000 years, the curiosity seekers
and treasure hunters would have broken in.

How odd that they didn't with those Inca walls.
I'll have to take your word for it.

No you don't, I gave you the cites that show that plenty do.
I've never been there and have no plans to visit.

We do have this funky system called the internet
that allows you to check that any time you like.
I was under the impression it was sparsely populated.
<http://en.wikipedia.org/wiki/Northern_Territory>
233,000 population over 1/2 million square miles, with
half the population in Darwin, does seem a bit sparse.

Irrelevant to your original where your claimed
that no one would want to live there. Plenty do.

Well, let's grind the numbers and see how close we come to meeting the
soil support capacity for a pyramid. I try for the biggest, Khufu's
pyramid, which is 756x756 ft at the base, and 481 ft high.

Volume of a pyramid = 1/3 area_of_base * height

Isn't that for a three sided pyramid?
V = 1/3 * 756 * 756 * 481
V = 91.6*10^6 cubic-ft.

And why not just get the real numbers for the SANDSTONE blocks, and the
LIMESTONE capstones.

Just get the tonnage and block counts from the historical record.
Limestone is about 170 lbs/cubic-ft.

It differs depending on the region it is quarried from.
91.6*10^6 cubic-ft * 170 lbs/cubic-ft = 1.56*10^10 lbs

Ground loading = Weight / area_of_base = 1.56*10^10 / (756 * 756)
= 27,300 lbs/sq-ft

Guesstimations are fun. I think sandstone weighs more.
The average single story home weighs in at about 300 lbs/sq-ft
including the foundation but not the live load. Local code for my
clay soil area is 2,000 lbs/sq-ft maximum. I believe that on sand, it
can pass at up to 4,000 lbs/sq-ft max but I'm not sure.

The Khufu pyramid exceeds the ground loading code limit by a factor of
about 10 and will probably fail the plan check or get red tagged.

Haven't seen it sinking or tipping yet. After many many centuries.

Hi!

I'm planning a robotic facility [3] that needs to maintain hardware
(exchange defective parts) autonomously for up to 1000 years. One of the
problems is to maintain firmware and operating systems for this period.
What methods do you think are suitable?

Top priority is it must work about 1000 years. Price is not a big issue,
if necessary.

I thought about this:

ROMs/PROMs, replacing them when checksum fails.

ROM/PROM masters, being copied once a year to flash ROM.

1000 flash ROMs, refreshing once a year from the ones that still have a
valid checksum.

Non electronic masters:

Microfilm/microfiche
HD-Rosetta (ion beam engraved nickel disc)
glass CD/DVD
Paper [2]
punched cards

The drawback of the non electronic masters is their reader system which
can fail mechanically/optically (dust, gears, ...) and requires
electronic components/firmware themselves.

Is it possible to make robots or their spare parts that suffer only
minor degradation when kept as spare parts for 1000 years at good
storage conditions? semiconductors, inductors, (non electrolytic)
capacitors, circuit boards, plastic/metal structures, CCD/CMOS cameras,
actuators, solar cells, thermo couples, etc. Batteries are probably
difficult.

Thanks, Bernhard

I will tell you how to build the megalithic computer.

To build any computer we need logic gates, the complete set of em.

Out of the foot of a mountain you carve deep square canals, then
hollow out giant blocks from the bottom end so that they can float.

2 of these floatation devices lift a giant stone door in a 3rd canal
between them.

4 of these floatation devices with 2 giant door makes our AND port.

4 of these floatation devices with 2 giant door makes our OR port.

1 floatation device with a lever pushing a giant door downwards makes
our NOT port.

Well spaced out canals with lakes for pixles make up the monitor.

Run some kind of usenet teletext on it. One page per day. Things the
galaxy never knew it wanted.

If you prefer to think smaller. Most components would still work after
1000 years, except from those that wont of course. Then all
replacements fail at the same time. Most likely you wont have
something you probably need.

It would be a good idea to have more than one different solution for a
problem. Even bad solutions could turn out useful if enough time
expires. With every next replacement that is the same as the one
before odds are bigger it is broken.

Good luck!

Copper tools would never split granite, nor even limestone. But the
bronze age is called that for a reason. If the local resources are
reasonably rich in copper and column 2A (calcium, magnesium, etc OR 3A
transition metals zinc, etc.,) you can make many bronzes easily and many
of them do make worthwhile stone working tools. They are good enough that
they would not be left behind. And era scavengers would quickly hoover up
any that did get left.

Hardness of Egyptian materials on the Mohs scratch test:
copper tools = 2.5 - 3.0
bronze = 3
limestone = 3 - 4
iron = 4 - 5
granite = 6 - 8

A'course, you wouldn't be a very smart worker if you sanded away your
copper tools on a rockface all day. You'd probably get a serious
talkin-to from your supervisor, maybe worse in those days.

Consider that lead, in the form of bullets, is capable of spalling and
fracturing stone, despite its Mohs hardness being about nil. Consider
what a copper chisel, propelled by a hammer, acts like.

Anyway, even the ancients knew you can bash hard rocks into soft rocks.
Even if copper tools suck as much as we imagine they should, they still
had random stones of granite, flint, etc. Not as elegant as copper, but a
lot cheaper I'll bet. That still leaves granite a challenge, but
limestone, c'mon, really now.

Consider what the hammer will do to the chisel. The theory behind a
chisel is that the small chisel to stone contact area, produces more
pounds per square inch than the larger contact area between the chisel
and the hammer. Skipping all the calcs because I'm in a hurry today,
my guess(tm) is that the copper chisel will rapidly be reduced to a
shapeless blob or at least show a severe case of mushroom head by a
stone hammer.

My metals book is at the workplace, but i'll bet that there are some
pretty hard bronze and brass alloys. Maybe i'll remember to look it up.
Given a few hundred years some smith is very likely to find a harder one.

Therefore they had 450 to 900 years to convert bronze weapons into
tools. Yep, it's quite possible that they used bronze tools to build
the pyramids.

They used Copper tools. The pyramids were mostly sandstone. There
were some granite blocks, and more as the builds progressed. There was
limestone used as the top covering on at least the Great Pyramid at
Cheops.

And YES, they DID chisel HUGE granite obelisks with copper tools as
well. The biggest the world has ever seen. They used fire to soften the
stone along the trenches they dug while quarrying the obelisk body.

The mystery is how they moved them and especially how they erected
them.

No impulse of stone to copper, only impulse copper to copper and

That's the basic idea. A little force over a large area (chisel head)
converts to a large force over a small area (chisel tip). However,
that doesn't change the basic requirement that the chisel be harder
than the workpiece. If not, the workpiece will soon dull and deform
the chisel.
I haven't tried building actual tools, so I don't
know if it actually will work, but, given my limited experience,
it is something I would try.

I haven't tried it either. Here's some copies of Egyptian copper
chisels with some interesting commentary:
<http://www.flickr.com/photos/45841296@N00/sets/72157624066603759/>
Just one problem. There's not enough fuel in Egypt to do such work.
Firewood may have been imported from a nearby area with plenty of
wood, such as Lebanon, or they burned dried dung, which doesn't
produce a particularly hot fire.
<http://en.wikipedia.org/wiki/Dry_animal_dung_fuel#Africa>

Or they just imported the copper tools from
where ever there was fuel to make them.

Maybe. MatWeb shows 300+ assorted bronze alloys and their
characteristics:
<http://www.matweb.com/search/DataSheet.aspx?MatGUID=66575ff2cd5249c49d76df15b47dbca4&ckck=1>
You need to register to do material comparisons by properties.

Conversion chart from Mohs to Rockwell A hardness:
<http://www.efunda.com/units/hardness/convert_hardness.cfm?HD=HM&Cat=Steel#ConvInto>
<http://www.cidraprecisionservices.com/mohs-conversion.html>

The problem is that the Mohs test is a scratch test that is intended
for rocks and minerals, while the various Rockwell tests are
indentation or penetration tests, appropriate for metals. This
difference makes conversion between Mohs and Rockwell hardness
somewhat problematic. There will be numbers for both types of test
for bronze, but you will not find a Rockwell hardness number for
granite or limestone. The penetrator will shatter the stone and now
show a measureable indentation.

This might help define the range of expected values:
<http://www.allaboutgemstones.com/metal_jewelry_bronze.html>
"Bronze can be a harder metal which has a hardness of between
5.5 to 6.0 on the Moh's scale, and a Vickers Hardness (VHN or HV)
of between 60 (fully annealed) and 258 (cold worked)."

Thank you. That is better than what i could have dug out of my metals
book.

It strikes me that the robot facility will have to adapt to changing conditions over the next 1000 years, and thus the instructions sets / firmware will also change as part of the adaption / learning process. Thus the robotics facility does not need to have the original instructions on hand for a 1000 years.

The robotics facility, instead, needs to be able to archive changed instructions sets / firmware and determine when it is appropriate to scrap the last modification and revert. And determine what the current "state of the storage art" is at any given time to create new archives. (It's fairly obviousthat you would not get a group of humans to do that with fidelity for that1000 year period.)

I would suggest that a robotics entity that capable and adaptable would notbe appropriate on our lone human planet. And if you built it on the moon, I wonder what use it would be to a failed civilization, which is an entirely probable outcome in the next 1000 years. If so assumed, the robot's task would appear to need revision to include an interface to humans back on Earth as a Rosetta facility.

Talk about project creep....

built it on the moon, I wonder what use it would be to a failed
civilization, which is an entirely probable outcome in the next 1000
years.

I don't buy that last. Its done fine for countless millennia
so far and will survive the next one fine too, you watch.
