CSPICE_RECRAD converts rectangular (Cartesian) coordinates to
right ascension, declination coordinates.
Given:
rectan the array(s) containing the rectangular coordinates of the
position(s).
[3,n] = size(rectan); double = class(rectan)
the call:
[range, ra, dec] = cspice_recrad(rectan)
returns:
range the value(s) describing the distance of the position
from the origin.
[1,n] = size(range); double = class(range)
ra the value(s) describing the right ascension of the position
as measured in radians.
[1,n] = size(ra); double = class(ra)
dec the value(s) describing the declination of the position as
measured in radians.
[1,n] = size(dec); double = class(dec)
'range', 'ra', and 'dec' return with the same
vectorization measure, N, as 'rectan'.
Any numerical results shown for this example may differ between
platforms as the results depend on the SPICE kernels used as input
and the machine specific arithmetic implementation.

Scriptless lotteries on bitcoin from oblivious transfer
Lloyd Fournier<EMAIL_ADDRESS>https://twitter.com/kanzure/status/1171717583629934593
Introduction
I have no affiliations. I’m just some guy. You’re trusting a guy to talk about cryptography who got the date wrong. We’re doing scriptless bitcoin lotteries from oblivious transfer.
Lotteries
Imagine a trusted party who conducts lotteries between Alice and Bob. The goal of the lottery protocol is to use a cryptographic protocol without having a lottery trusted party. The idea is that the honest parties have a 1/n chance of winning each time.
Scriptless
Bitcoin has a way of specifying spending rules on coins. We use a cryptographic protocol to realize the conditions under which the coins can be spent. The conditions can be spent, and somehow the person will be able to magically arrive at a signature. You can use instead of OP_CHECKMULTISIG a threshold multisig scheme, or you can replace HTLC by using “adaptor” signatures. These two things, you can pretty much replace most of the useful stuff you can do with bitcoin script. I think you can do almost all of lightning, but Andrew who came up with adaptor signatures said no you can’t– timelocks maybe.
Scriptless is interesting because they are more efficient and more private. Also, it’s interesting to know what w ecan do and can’t be done without script. What do you really need scripts and opcodes for?
https://bitcointalk.org/index.php?topic=355174.0
“..I think the multi-party lotter y scheme still rates as the most advanced usage of script yet found in the wild.” - mike hearn, this was before lightning but it’s still up there.
So what we will be doing today is showing a lottery that doesn’t use a script at all.
Lottery without a trusted third party
You need to fairly generate randomness, no OP_RANDOM, you need a few other requirements that I am going to skip over apparently.
Coin tossing
There was a seminal paper in 1981 called “Coin flipping by telephone” but people quickly called it coin tossing instead or something. This was Manuel Blum in 1981. Alice sends a commitment to a coin toss to Bob, Bob sends his coin toss back, Bob checks Alice’s result against the commitment. The result is computed against both coin tosses.
Hash-commitment coin tossing
Here is how the bitcoin version works. Alice chooses a random bit, and she commits to it with a hash function with a long random string or nonce. Bob sends his value, and Alice sends the value. Hopefully, no party aborts. The thing to make note of is that you can get Alice, she learns the output first. There’s no way to solve this problem, but you can sprinkle some blockchain to solve some problem, but generally Alice always learns the value first. She might not release the preimage to tell Bob that she lost. So a lottery protocol has to overcome this.
First attempt at lottery protocols
https://bitcointalk.org/index.php?topic=277048.0
Many of the original protocols use collaterla to force both parties to reveal pre-images. Adam Back came up with a more appropriate idea, which is that if some party doesn’t do something at some point, then they just lose all the money instead.
Miller-Bentov 2016
There were quite a few academic papers after that thread, like 4-6 papers or something. There was one that succinctly summarized the idea with the “Zero-collateral lotteries in bitcoin and ethereum” paper. So you both have a fund transaction, you sign into it, but you already have transactions spending from it before you put it on the blockchain. Each transaction acts like a state. The funding goes down; Alice can move it to the next state by revealing her preimage, and then– so she already has that transaction signed, she needs the value to go to the next state, and then in the next state, Bob can take the money if he reveals a value such that his value and Alice’s value can do something interesting. Otherwise, he can’t do anything except wait for a timeout where Alice gets the money. There’s no collateral in this. It’s what we want. The winner just takes out the bitcoin with probability 1/2.
This is probably the simplest hash-commitment lottery protocol. What you can see is that you got these hash preimage reveals, but if we want to make this scriptless; we can replace HTLCs with adaptor signatures normally, but in this case we can’t because you’re revealing the preimages but you’re actually spending the money on a function of the two preimages. It’s some predicate on the two preimages determines whether it can be spent, it’s two preimages and a predicate. It’s a non-trivial use of script, it’s interesting that we can do this without any script at all.
Scriptless lottery through oblivious transfer
We want Alice and Bob to pay into a funding setup transaction, and then we want no script used at all to do this. We’re going to change the cryptographic primitive to oblivious transfer instead of coin tossing. Manuel Blum also came up with this idea in 1981. He came up with two ideas for doing random bits. He did coin tossing, and also oblivious transfer.
Oblivious transfer is where Alice transmits 1 of n messages to Bob of Bob’s choosing but Alice doesn’t learn which one that Alice transmitted. The sender doesn’t know which message was sent. The receiver only gets one of the messages. Alice has n messages, Bob chooses one that he wants to learn, Alice doesn’t learn which one he learns. That’s the basic idea.
You can get a random bit from that. Bob chooses a random bit, Alice chooses a random message, and Bob learns the message according to his bit. He learns the result after Alice sends her bit over, he sends the message he learns back to Alice, and Alice looks and sees hwich message did he choose to learn, and then she picks based on that.
Oblivious signing
It might not be clear how to go from that to some kind of bitcoin protocol. We’re going to do oblivious transfer of signatures. It’s not just “messages” arbitrary. It’s not quite obvivious transfer, though. If we replaced the messages with just signatures, what would happen is that Alice could just put one message as a signature and the other one is just garbage and then Bob does oblivious transfer and he gets the signature and he thinks everything is fair but Alice knows which message he got because the garbage was the other one. So we have to have some verifiable oblivious transfer, called oblivious signing.
Bob chooses which message he wants signed, and Alice doesn’t know which one was signed. We’re going to use oblivious signing. We have a fund transaction that we sign last, and we first sign the child transactions. By the way, this is all predicated on having Schnorr signatures and you could probably do it with ECDSA but that’s not this talk. You have to sign the transaction scaffold after you choose the key securely. You have to sign all the abort transactions and the lottery winning transactions. For the Bob wins transactions, you have to do oblivious signing, at Bob’s choosing, but Alice doesn’t know which one he chose her to sign. Then you sign the transactions to fund. Also, these transactions have timeouts where the other party wins. If you have a secure oblivious signing protocol, then each party would win 50% of the time here. So the only options are either Alice wins and Bob timeout loses, or Bob wins and Alice timeout loses or something.
Adaptor signatures (Poelstra 2017)
I am sure you have seen these before. Here they are in multiplicative notation instead. You have an auxiliary point, this conditional point that you add to the signing algorithm. You multiply the nonce value by this. The s value you get out of the signature is missing the discrete log of the condition. There’s Y condition and y the satisfaction of the condition. An important feature is that the signer learns little y once they see the signature. So then you learn little y when you see the signature on the blockchain.
Oblivious signing again
Alice to give Bob adaptor signatures where Bob only knows the completion for one of them. We need Bob to know a discrete log of some point but only one of some set of points. So a pedersen commitment is given of a certain form; it’s impossible to decommit to more than one value without knowing the discrete log of some h with respect to g.
If we can instead fix C to 0 or 1, then the committer can only know the discrete log of T or TH^(-1). They can only know the discrete log of one of those two.
To put these two ideas together, the idea is that you can only know the decommitment for one pedersen commitment, and adaptor signatures. Bob has a choice, 0 or 1, he generates a random y value, and— Alice creates two adaptor signatures, one on T and one on TH^(-1) and then sends them over to Bob. He has to verify both of them, that they are all valid adaptor signatures. He verifies both of them, and then he completes one. That’s it, that’s how we get oblivious signing.
Security
Security for the sender is that if Bob completes both adaptor signatures, saying that he reveals the completion, or revealing the discrete log of the condition, then we’re going to learn the discrete log of T and TH^(-1) which Bob learns– so the discrete log.. violates that the discrete log is hard, so Alice has that security in that respect.
It’s information theoretically impossible for Alice to learn which choice Bob made, it’s indistinguishable from random.
I came up with that, I was very happy with myself. I don’t invent cryptographic primitives very often. I decided to call it “oblivious signing” and then I googled it and found out that someone else already wrote it up, in 2008 (2006?).
Two-party oblivious signing
Not so fast! our transaction outputs are locked by joint public keys. Both Alice and Bob have half the public key, so we can’t just use that algorithm by itself, we have to change it a bit. I think these changes preserve the security from the slide before.
They both choose joint nonces, we did this already. Along with T, Bob sends his half adaptor signatures for m0 (BobWin0) and m1 (BobWin1) under B0 and B1. Alice calculates the full adaptor signatures and sends them back to Bob. So we’ve managed to do two party on the joint public keys.
That’s it, we did it. Just to recap on this, so now Alice posts the fund transaction, she picks one or picks zero, Bob now if he chose the same bit as Alice he is able to take the money, and otherwise Alice takes it. With 50/50 probability, Alice is going to win the lottery.
Summary
Lotteries were previously an eample of something that could only be done with non-trivial scripts. But they can actually be done without script, and actually they can be done efficiently without script and still on-chain. Obvliious signing with Schnorr signatures is secure and efficient (at least as it is used here).
Some unsubstantiated claims: you can do lotteries with different odds by doing 1/N oblivious signing rathe rthan 1/2. You can cooperatively complete the lottery in two on-chain transactions. I think you can execute the cooperative protocol in a payment channel, where it’s a UTXO in a state of a payment channel, and even do it in a “multi-hop” but that’s conjecture. There can be a guy in the middle who has a lottery on his left hand side and a lottery on the right hand side, and he’s guaranteed to lose one and win the other and he doesn’t know which one and he will be a man in the middle, and you can do that recursively so you can do many hops of that.

BeagleBone Black, like the Raspberry Pi, is a small, inexpensive computer that runs Linux. It’s smaller than a deck of cards and you can buy one for about forty-five dollars ($45.00). The device is made by CircuitCo in Richardson, TX, USA.
It Just Works
BeagleBone Black runs Linux right out of the box. Steps required:
- Plug in the micro-HDMI cable for the monitor. See the “Gotchas” section about micro-HDMI below.
- Plug in the keyboard & mouse via the USB port. You might need a USB hub because the board only has one USB port.
- Add power via the mini-USB port or the 5v power connection.
After a few minutes of boot time, we have a fully-functioning Linux computer with a GUI, Firefox browser, and other tools.
The BeagleBone Black has 2GB of flash storage on the board, and part of that is used for Linux. Here’s a screenshot after just a few minutes of ownership.
Documentation
All of the paper documentation for the BeagleBone Black fits on a slip of paper roughly the size of two business cards. The meat of the documentation resides on the device itself. To reach the electronic documentation:
- Plug the BeagleBone Black into a USB port on your laptop.
- The board will appear as a USB storage device. One of the files at the
root of the storage device,
START.htm
, contains the documentation. It can be viewed in a web browser.
The documentation recommends against MSIE.
Gotchas
The manufacturer included a mini-USB cable with the device, so you can power it up right after you rip open the package. Gotcha: You need a micro-HDMI cable (or adapter) if you want to attach a monitor. I would have preferred a micro-HDMI-to-HDMI adapater in the box instead of the mini-USB cable. That’s a little nit-picky on my part since micro-HDMI cables are easy to find at Home Depot.
A quick shout-out to Home Depot: Their store-brand cables let you test the cable end without opening the package, right in the store. Excellent package design by Home Depot.
My second “gotcha” is more important: The curl
command did not behave as flawlessly as it did with the Raspberry Pi, so I was not able to install Ruby as quickly as planned. Details below.
Installing Rails
I will have to cover Ruby and Rails installation in a future blog post because my initial attempts were not successful. RVM, Ruby, and Rails installed easily with Raspberry Pi, even though the compilation time was long. With the BeagleBone Black, I received the following in response to the curl
command:
1 2 3 4 5 6 |
|
Maybe it’s time to try RBEnv? I’ll post a solution when I find it. Or… if a reader of this blog already has a solution for the BeagleBone Black Rails installation challenge, please post in the comments below and I’ll credit you here.
BeagleBone Black vs. Raspberry Pi
Which is better, BeagleBone Black or Raspberry Pi? There’s no clear winner in my opinion. It’s a matter of trade-offs:
- The ‘Bone runs Linux right out of the box, while it takes some time to get Linux running on the Pi, unless you buy a card pre-configured for the Pi.
- RVM, Ruby, and Rails installation was painless on the Pi even though compilation time was long. The jury is still out w/r/t RVM on the ‘Bone.
- Cost-wise, they’re within ten bucks of each other. That’s a wash.
- The ‘Bone has more Ardunio-like provisions for digital projects.
- The Pi includes an RCA output for older TVs. Plus the Pi uses standard HDMI, so there’s no need to get a special micro-HDMI cable.
I’ve owned my ‘Bone for just over 24 hours. Lots more to learn. Looking forward to it!


Hi, I’m an engaged citizen in . I feel that equal marriage be legal and I Obamacare. I also believe that gun laws should be . On the foreign policy front, I think the US needs to be of Israel’s expansion.
It’s also important to me that the United States military engagement abroad. In fact, I think the US should the military budget and the drone program. On the economic front, I feel we should social security and the big banks. Oh, and by the way, marijuana be legalized in every state.
It is important to me that the Unite States assault rifles. At the end of the day, I want government to be hands and I want the US government to military engagements abroad. I moderately believe that the government collect phone and computer records to fight terror. And ultimately I want government to keep religion in the public sphere. Oh, and by the way, I think undocumented immigrants have a pathway to citizenship.


[ aws ]
AWS Organizations is a web service that enables you to consolidate your multiple AWS accounts into an organization and centrally manage your accounts and their resources.
This guide provides descriptions of the Organizations API. For more information about using this service, see the AWS Organizations User Guide .
API Version
This version of the Organizations API Reference documents the Organizations API version 2016-11-28.
Note
As an alternative to using the API directly, you can use one of the AWS SDKs, which consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, and more). The SDKs provide a convenient way to create programmatic access to AWS Organizations. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For more information about the AWS SDKs, including how to download and install them, see Tools for Amazon Web Services .
We recommend that you use the AWS SDKs to make programmatic API calls to Organizations. However, you also can use the Organizations Query API to make direct calls to the Organizations web service. To learn more about the Organizations Query API, see Making Query Requests in the AWS Organizations User Guide . Organizations supports GET and POST requests for all actions. That is, the API does not require you to use GET for some actions and POST for others. However, GET requests are subject to the limitation size of a URL. Therefore, for operations that require larger sizes, use a POST request.
Signing Requests
When you send HTTP requests to AWS, you must sign the requests so that AWS can identify who sent them. You sign requests with your AWS access key, which consists of an access key ID and a secret access key. We strongly recommend that you do not create an access key for your root account. Anyone who has the access key for your root account has unrestricted access to all the resources in your account. Instead, create an access key for an IAM user account that has administrative privileges. As another option, use AWS Security Token Service to generate temporary security credentials, and use those credentials to sign requests.
To sign requests, we recommend that you use Signature Version 4 . If you have an existing application that uses Signature Version 2, you do not have to update it to use Signature Version 4. However, some operations now require Signature Version 4. The documentation for operations that require version 4 indicate this requirement.
When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools.
In this release, each organization can have only one root. In a future release, a single organization will support multiple roots.
Support and Feedback for AWS Organizations
We welcome your feedback. Send your comments to<EMAIL_ADDRESS>or post your feedback and questions in our private AWS Organizations support forum . If you don't have access to the forum, send a request for access to the email address, along with your forum user ID. For more information about the AWS support forums, see Forums Help .
Endpoint to Call When Using the CLI or the AWS API
For the current release of Organizations, you must specify the us-east-1 region for all AWS API and CLI calls. You can do this in the CLI by using these parameters and commands:
For the various SDKs used to call the APIs, see the documentation for the SDK of interest to learn how to direct the requests to a specific endpoint. For more information, see Regions and Endpoints in the AWS General Reference .
How examples are presented
The JSON returned by the AWS Organizations service as response to your requests is returned as a single long string without line breaks or formatting whitespace. Both line breaks and whitespace are included in the examples in this guide to improve readability. When example input parameters also would result in long strings that would extend beyond the screen, we insert line breaks to enhance readability. You should always submit the input as a single JSON text string.
Recording API Requests
AWS Organizations supports AWS CloudTrail, a service that records AWS API calls for your AWS account and delivers log files to an Amazon S3 bucket. By using information collected by AWS CloudTrail, you can determine which requests were successfully made to Organizations, who made the request, when it was made, and so on. For more about AWS Organizations and its support for AWS CloudTrail, see Logging AWS Organizations Events with AWS CloudTrail in the AWS Organizations User Guide . To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide .

THE NIGHTMARE BEFORE CHRISTMAS A film review by Brandi Weed Copyright 1993 Brandi Weed
Since I live not too far from Los Angeles (and the El Capitan), I've had the good fortune to see THE NIGHTMARE BEFORE CHRISTMAS this weekend.
Okay, let's get the bad news out of the way first. The film is only 75 minutes long, so some things which are set up are never very well explained; similarly, the plot is rather thin (but I've seen thinner films do well--HOME ALONE 2, anyone?). Ideally, this film should have been 90-100 minutes long.
Now the good news: It's a genuinely likable film, grotesque and heart-warming at the same time (don't ask me to explain how they pull it off). It's also very funny, with great ghoulish sendups of Christmas sentiment and a surprise reference to The Fly (I'll let you experience that yourself!). The animation is terrific, and you may end up seeing it twice (as I did) just to look at some of the wackier character designs.
The score by Danny Elfman is decent (people who've complained about his "la-la-la" tendency can complain again), and so are the songs, which are definitely influenced by/stolen from Kurt Weill. Three songs in particular stand out: the opening song about Halloweentown (which could be easily used as a new score for Disneyland's Haunted House), a song sung by three nasty little urchins about kidnapping Santa (sample lyric: "Kidnap Santa Claus/Stuff him in a box/Lock him up for 90 years/and see if he'll talk!"), and a Cab Calloway-esque number by the film's nominal villain Oogie Boogie (who also has a few really eye-popping scenes of animation).
On the whole, I'd say it's definitely one of the better Tim Burton films (he did not direct, but he seems to have come up with the story and the main character designs), and probably ties with EDWARD SCISSORHANDS for being his best film. It'll be in wide release this Friday (the 22nd): go see it!

--- layout: page title: Equipment - External Enclosure description: Your camera will be exposed to the elements 24 hours a day so it should be protected by IP-67 enclosure permalink: /equipment-external-enclosure/ image: img/equipment/equipment-external-enclosure.jpg ---
Your camera will be exposed to the elements 24 hours a day, 365 days a year and therefore needs to be protected from the elements. There are two options: buy a commercial CCTV enclosure (of which there are many to choose from) or make your own.  However, we have found that it is well worth paying a little extra for a commercial camera enclosure for the following reasons:
Most enclosures are described in their sales literature as being waterproof but our experience is that many aren’t. One reason is that CCTV enclosures are rarely designed to be pointed upwards. What we find is that overhangs and run-offs designed to direct water away from seals will do exactly the opposite when the camera is pointed at extreme angles. One of the best enclosures we have seen is the Genie TPH2000 enclosure. This is an IP-67 rated enclosure which comes with a 12v internal heater and can be purchased for around £50 to £55.
The IP rating is the ‘ingress protection’ rating for dust and liquid. Our recommendation would be IP rating of 5 for water ingress; the Genie offers a rating of 7 (will withstand immersion up to 1m). A description of the IP rating system is available here (Wikipedia)
Housings such as the Genie provide a thermostatically controlled heater for dew control. If this option is used we recommend a separate 12v power supply. Firstly, to power a heating element a supply of at least 2A will be required, and secondly, the switching of the thermostat creates electrical noise which may interfere with camera operation.
[gallery]
Some enclosures require a 240v supply; for safety we do not recommend using any enclosure that requires 240v as providing safe external mains supply increases complexity and installation cost.

Eclipse vs IntelliJ
Over the last two months at the new job I've been using a new (for me) IDE from JetBrains called IntelliJ IDEA, or IntelliJ. IntelliJ pioneered a lot of the IDE refactoring in the Java world, but they're also a pay solution whereas Eclipse is free, as in beer _and_ as in speech.
Nic sent me a link to an IntelliJ blog entry that is collecting reviews comparing the two. I may have to write one, later when I'm more familiar with IntelliJ.
In Eclipse, If I click on a variable then every usage of that variable is highlighted in the document and in the scrollbar for easy scrolling to the relevant location. And it uses zero screen real-estate - I find IntelliJ a lot less dense than eclipse (which is probably good for beginners, not so much for power-users).
Similarly, if you click on the return term, then the points in the method which return are highlighted. If you click on an exception, the points where that exception are thrown are highlighted.
These are unbelievably useful for grokking other people's code.

We deploy all of our J2EE apps to BEA's Weblogic Server system.
With their latest version 9.2 of the Weblogic Server their Development IDE has switched to now being Eclipse based.
Having only played around in eclipse briefly before, I can see how it will work well in place of their old development IDE 'Weblogic Workshop'.
I'm on course this week and we're using it, unfortunately I'm not sure if it is the shitty machine configuration, a shitty installation, or the product itself, but it seems to be hanging and freezing quite a bit.
One person, who probabaly hasn't used it anymore than I have, piped in saying that regularly eclipse is super stable, and its when they build these extra perspectives that it's stability wanes.
We'll have to see becuase if it hangs this much during regular development I'll be moving on to something else.
...and here I was thinking this would be an epic tale of how J outwitted the machine, emerging triumphant once again!
Control-Shift-F7 highlights a variable or method in a file. Nowhere as easy to use as Eclipse, but it's there. Phew! Missing that one was really hurting.

one of the scientists here's a look at
the gate and compared it with earlier
16:52
years nineteen ninety-six and saw that
they have been sent up within the
16:55
northern part of the yellowstone
collabera
16:58
centered around here not far from the
north geyser basin and this was unusual
17:03
because it was a different area than the
effort witnessed uplifting before
17:09
their data shows but over the last seven
years ground-up numbers has been
17:20
should they be wiring
17:25
there at least two possibilities for why
we might get tough with at norris
17:30
one possibility is that somewhere deep
in the system ten to fifteen kilometers
17:34
there is a small injection of magma
17:37
that's pushing rock out of the way and
causes a mud
17:40
another possibility is that gas build-up
is causing some of the applicant asking
17:45
to be coming from the magma
17:47
or from the hydrothermal systems
17:50
did take the phenomena going
17:56
but it'll never reach the surface
17:58
this activity would die down that's a
very common situation it could be that
18:03
michael will reach the

18:12
if mcquay surface we could go into a
much
18:19
morris is not the only area if the park
18:21
that's been causing concern
18:26
in nineteen ninety nine
18:27
a team of scientists from the u_s_ to
launch a consensus
18:31
began a detailed study
18:40
one striking new feature
18:43
caught our attention
18:47
it was a seven hundred meter long
boldchat
18:50
which rose thirteen inches above the
lake floors
18:59
to get a better look at this new feature
19:01
they used to remove the operated camera
19:06
the images revealed
19:08
the sentiments resting on the top of the
bulge
19:10
showed signs of disturbance
19:15
but it could be swelling
19:18
forcing the moment is the so-called
inflated claims is a sort of update
19:21
invariant beneath yellowstone lake
19:24
now that may at some point in the future
herald
19:34
the sixteen different lofty cooling
effect immediate area
19:39
subside the religious studies it is it's
really impossible to say what's gonna
19:44

19:46

the thing about yellowstone is it

means it is always doing something so
you have clearly have magma dot mary

he's also inflating the ground surface
which is going up and down over pizza
20:11
decades of centuries
20:13
this activity is not unusual the others
20:17
difficulty for scientists
20:18
is that many of the signs they rely on
to protect eruptions other volcanoes
20:23
accompanied the time of youngstown
20:28
there's another warning sign our the
scientists comes in

tens of comfort beneath the surface if
not the load to get from there to the
20:48
make a powerful stuff in it does look
like breaking rocks
20:52
that breaking the rock generates
earthquakes that we can protect those
20:55
who we know the magnet on his way out
21:00
many earthquakes that yellowstone's very
seismically active region there anywhere
21:04
between about one thousand three
thousand earthquakes here in any given
21:09
most of the earthquakes is so small
21:11
but they can only be detected by
seismologist
21:15
but they can be exceptions

22:01
although the collective group was

22:04
it could have been so much worse
22:08
because the earthquakes of magnitude
seven and higher
22:12
have the power to trigger election

people have found a correlation between
22:20
large earthquakes standoff anger at
least
22:24
that may happen in the past in
yellowstone and distant past and it
22:28
potentially could happen in future
22:33
larger earthquakes pose a risk because
they can fracture of the heart of the

the magma chamber is over three times

many people might think that killer

although there's more than enough rocked

26:28
statistically it's much more likely to
commit starting this morning
26:37
but didn't think that the science of

26:45
far more likely that if there is an

26:49
instead price comparison

the yellowstone sciences don't believe
the even smaller fraction is growing
26:58
the kinds of things that we see
27:00
have been going on ever since people
have been coming to the park and
27:04
geologic evidence seems to indicate that
they've been going on for at least the
27:07
last ten thousand lives
27:10
so at this point in time we don't really
see indications from ground operation
27:14
from earthquakes or from cast that
there's any sort of really unusual
27:17
activity going on at yellowstone it with
the precursor to a of all can corruption
27:27

lifetime
27:35
this is a rock and assistant i don't
know
27:38
but i'm very interested in finding out
27:41
we could have an eruption extn
27:42
but we could have to wait many thousands

was another eruption in my lifetime but

the chances of that happening in our

are extremely remote

if it were to happen however

the nations of the planet would pull
