Aliens done it.
Obvious icon is obvious.
Scientists from the USA and Greece have returned to the site where, in 1901, a device widely regarded as the world’s first computing mechanism was found, in the hope that similar devices can be found. The device in question is the Antikythera Mechanism, an apparatus of interlocking gears dated to the first century BC. The …
"It's not alien, it's Atlantean!"
Depends who you ask -- plenty of fairyfanciers out there who will gleefully tell you that Atlantis was not a human construct.
This really is David Icke or El Ron Hubbard territory.
It was really a free gift out of an Atlantean corn flake packet - a kids toy.
"El Ron Hubbard was an entirely sane man who figured he could swindle gullible people out of money and thought, "Well, why not?"."
Indeed, why not? We let the financial services industry swindle the gullible out of their money, and they haven't even given us any pulp fiction novels, or even a proper cult (if we overlook the Cult of Goldman).
"So there is no mechanism for protecting against a pressure differential between source/target locations for a stargate?"
It's uncanny how XKCD already has an answer to anything - http://what-if.xkcd.com/14/
"would happen if you opened a portal between Boston (sea level) and Mexico City (elev. 8000+ feet)?"
"...It's uncanny how XKCD already has an answer to anything - http://what-if.xkcd.com/14/..."
Actually, I recall the same plot line being used in a 1950s British SF short story. The Mad Nazi Professor (tm) develops a dimensional gate to enable armies/battleships/etc to be rapidly moved to tactically superior positions.
The Hero alters the gate settings to position the first test portal at the bottom of the Atlantic, and the whole research centre is destroyed by the lake that suddenly appears on top of it....
Excepting that the gates contained various technologies to ensure that atmospheres (gaseous or aqueous) wouldn't pass through the gate. Smart folks those Alterra. Without this little plot mechanism, the entire "Atlantis" series would not have been possible. Every time they opened a wormhole to a space gate, Lantia's atmosphere would go roaring through the event horizon, dragging all the unfortunates in the control room with it.
"Excepting that the gates contained various technologies to ensure that atmospheres (gaseous or aqueous) wouldn't pass through the gate."
1) You spend far too much time watching sci-fi, Sheldon.
2) How does the gate know the difference between an atmosphere and you breathing, between a cup of water or a wet exterior and the sea coming through? For any race, breed, species that happens to use it (what about a slug?) How does it apply force to individual molecules to stop them transiting after having determined their part of the organic system that wanted to travel through the gate, compared to - say - some bacteria in the ocean or in your breath?
There's a reason sci-fi glosses over such things - they are impossible to work simply in practice because of such issues (e.g. "Heisenberg compensators" et al). And if you have two stargates, you have an infinite energy source, which is probably quite capable of blowing up both of them if you do something wrong (e.g. a single particle gets trapped in an inter-gate loop with differing gravity on both sides, where it then gains more and more energy from gravity until it blows the hell out of the gate - space-debris-like).
3) It's a joke about a sci-fi series, something that should NEVER be taken seriously. But apparently you missed that the first time round.
Diving on an ancient wreck looking for the coolest stuff in the world. Even if they don't find anything it would still be a fantastic experience and to think they actually get paid to do it. Do you think it's too late to send them my CV? How about if I just take a few vacation days and do the dives gratis... please?
I wouldn't expect a ship to carry any, there were known navigation methods that didn't use one and as you say, it would have been hideously expensive (you'd need to buy about 5 years of the time of someone like Archimedes to get one).
I saw one theory that said that the missing dial on the back (period deducible from the gearing) might have highlighted the major games. A sporting almanac for some super rich merchant? That makes sense, wealthy sports fans spend ludicrous amounts on being one up on their peers to this day. Think of a device that tells you when's a good time to make a bet (this event, that conjunction of planets).
When evaluating the various theories on offer, there's one thing to consider. People back then were people, not aliens. We don't have ordinary merchant ships with above military grade experimental navigation systems today, but we do have sports nuts with more money than sense.
There was a TV programme about it a short while ago (BBC 3 / 4 ?) and they had a couple of engineering experts examining the mechanism to recreate the various parts. They were able to make most parts really quickly; some took less than an hour.
Most of these would also have been fairly easy to make by the standard of skills of the time; the big issue was that people producing the parts needed to understand the mathematics of the calculations behind the movements of the planets that were required for construction. There would only have been a few such people capable of this.
Add to that, it would only have been the aristocracy / theocracy that would have allowed the construction. Quite probably, they would have ordered a few to be made by one person and these may possibly have been shipped together. (But probably not)
We can be an awesomely inventive species when we choose; it's a shame that we so often turn that talent to finding ways to hurt other people in new and exciting ways.
Been at least a couples of programs on BBC about it. One is an Horizon type of program with loads of wizzy graphics and jumping all over the place, the other is more of an investigative program where you actually get the persons involved explain their line of thoughts and mistakes - just like Horizon use to be like.
I'm pleased to hear that there's at least one other person that thinks Horizon has degenerated to the point of being barely worth the effort. I used to tolerate the insane camera work because there was at least some useful information, but in recent years the bit rate has dropped to a point where the actual information if delivered sensibly, would have occupied about 15 mins.
Horizon: They don't want to scare off the casual viewer. When was the last time you saw a diagram or graph on it? Much easier (on the eye) to spend 10 minutes watching people on a beach throwing a ball to each other while 'explaining' the difficulties of shooting a space probe from one planet to another.
When was the last time you could actually watch an entire episode of Horizon? The bit rate is so slow that a four year old child could follow the story. I cant watch it anymore, despite the tantalizing synopsis in the RT or on the EPG, I find it so frustrating. It makes me feel like I'm some sort of genius bored by a potentially interesting subject. why cant they cant speed things up a bit and get more detail into the time alloted?
Maybe I should just fit a Matrix port and be done with this broadcast information upload?
5th disk wobble was a common failing with the first series of Sinclair "Antiky"s: some owners just blamed the erratic results on a hypothetical "chunty aether" but others, as here, insisted upon a warranty repair. Of course this meant posting it back to Cambridge, and sadly this mail ship didn't make it: the dive is likely to find a large collection of bills and direct marketing for The Amphora Stora.
Even less-known fact: the largest surviving collection of "Antiky"s is in some boxes balanced on a radiator at the back of the Cambridge Sorting Office (it was raining so the driver left a "sorry you were out" card at Sinclair Research)
Speaking of having difficulty watching supposed science television programming, this coincides with the dumbing down of everything technical.
Education systems across the world are teaching to the lowest common denominator such that what I was learning in 7th grade back in the early 70's, is about the level of complexity taught in 11th grade today. They lower the bar every year so the failure rate is not so glaring.
I say TFB for the dummies. We have to save the students that are smarter than the rest of the class. THOSE students should be removed from the idiot farm and placed into gifted programs so at least they are not contaminated/taught to be stupid like the rest of the class will be.
The "aristocracy" does not want smart people, they want pliant stupid people like those who believe Fox News and Rush Limbaugh, Shawn Hannity et al. This is the reason why they want cuts to education and now to Public Broadcasting the last bastion of somewhat educational TV.
It constantly amazes me of the technology far more primitive societies were able to develop.
But is it possible that the Antikythera mechanism wasn't actually a prediction device but an attempt at one?
The location where it was found matches at least one description of the location of Atlantis, and at least one ancient supervolcano's caldera collapse could account for the island "sinking beneath the waves" as in the legend.
I suspect what actually happened several thousand years ago is that the island rose from the depths on a magma "bubble" to surface, meanwhile the magma pressure continued to build and the island was colonised by our human ancestors who built an advanced (for its time) civilisation using volcanic derived thermal energy to refine metals without conventional technology.
Eventually when the magma pressure exceeded the stress limit a relatively minor earthquake ruptured the walls and the island sank several thousand feet in a few months.
As the island sank the exposed magma eventually consumed it leaving a relatively flat seabed and little trace of the island or its inhabitants.
Well apart from the colony on the far side of the Moon that is...
