Some Sunday Thoughts-Thanks For Stopping By

‘The same idea occurs in Schopenhauer, for whom the truth of the world is Will, which cannot be represented in concepts.  Schopenhauer devoted roughly 500,000 words to this thing that no words can capture…’

‘…I too am tempted to eff the ineffable.  like my philosophical predecessors, I want to describe that world beyond the window, even though I know that it cannot be described but only revealed.  I am not alone in thinking that world to be real and important.  But there are many who dismiss it as unscientific cast of mind are disagreeable to me.  Their nerdish conviction that facts alone can signify, and that the ‘transcendental’ and the eternal are nothing but words, mark them out as incomplete. There is an aspect of the human condition that is denied to them. ‘

Scruton, Roger. Effing The IneffableConfessions Of A Heretic. Notting Hill Editions Ltd, 2016. Print. (Pgs 87 & 88).

Personally, I’m not sure that all naturalists and people in the sciences I’ve known wish to reduce the world to strictly mathematical laws, nor consign all domains of human endeavor to ‘non-science.’

Some people, I suspect, have the onboard wiring and have pursued learning which make them profoundly interested in order, patterns, and logic. Some people are just really smart and dedicate themselves to a particular problem or two, maybe possessing the genius and courage, even, to define a new problem after years of hard work of mastering a field, leading to genuine new knowledge.

I am grateful for the Mars Curiosity Rover, and the hundreds of engineers that worked for much of their professional lives to land this thing on Mars.  It’s still yielding valuable data.

But, I”m guessing there’s lot of waste and bureaucratic stasis at NASA. Perhaps a similar regression to the mean within institutions towards narrower ideas and ideologues happens here, too (if only x were removed, y will occur).

I see such outcomes partially caused by the decay of things, partially by design, and partially as a process of secularization (beneath the idealist and systematist lie human nature and reality). Such incentives don’t necessarily lead to leadership by the most knowledgeable, but over time, rather to leadership by administrative fiat and distant political winds.

Now, there’s arrogance, hubris and false pride to be in all of us, to be sure, and many sharp thinkers are no exception (in some cases the bigger the brain (or ego), the bigger the fool).  I don’t find foolish and/or earnest conviction in any short supply on this Earth.

To be fair, I don’t think this proves, nor does Scruton even attempt to prove, that the ineffable, therefore, exists (or if the ineffable does exist, as it reveals itself to us, that it requires saying or expression through us, nor through Handel or Bach or post-Kantian German thinking).

Such expression surely offers me consolation, though, for I take refuge in works of art.  I am profoundly grateful to walk at evening and listen to a few minutes of music:

I am profoundly grateful that I may share in someone else’s pain, suffering and disconsolation, across centuries, transmuted into an act of beauty and wonder, through a centuries-developed form and method (an orchestra is rather a thing of technical achievement, too, just as is a store-bought guitar or a Korg).

Sure, there’s much epistemological ignorance amongst some in the sciences and, frankly, within all of us.

Come to think of it, I think most of us manage one or a few things well, and mess up at least a few areas of our lives without even trying.  It’s also very, very tempting to talk about that which we know very little (this blog, for instance), as though something is known.

This may make me no more than a 2nd or 3rd rate idea man, taking, essentially, more than has been given.

For today, I suppose this will do.

Some Links To The Rolling Fork, MS Tornado-Life & Death

R.I.P.

Some tragedies happen because of a lack of knowledge, and a lack of knowledge distribution when it is matters most.

There were people sitting in homes and businesses in Rolling Fork MS, who knew it was storming, and knew they should probably keep an eye on the weather, and knew how to stay safe in most situations.

But they didn’t know there was an EF-4 or EF-5 monster bearing-down. They didn’t know they might have had minutes to live. These wind-speeds can sweep walls from foundations.

If these poor folks even knew what the storm-chaser driving-by knew, when he knew it, this could have made the difference.

It’s terrifying to think there could have been someone in that vehicle, hovering a few hundred feet in the air, being swept around this beast.

Accurate prediction[s] save lives.

Some of the experience of storm-chasers, and collected knowledge from that experience, already exists but needs to be channeled through complex and more predictive modeling to establish the science within these monsters.

This is where the new frontiers should be pushed.

Which Lens Are You Using? Some Links

David Hockney ‘On Secret Knowledge: On Rediscovering The Lost Secrets Of The Old Masters’:

——————

Optical devices were likely common practice more than is commonly known these days, way before the camera, the television etc.

As previously posted:

Just as optics revolutionized the sciences and the boundaries of human knowledge, from Galileo to Newton and onwards, Tim Jenison wonders if optics may have revolutionized the arts as well.

‘But still, exactly how did Vermeer do it? One day, in the bathtub, Jenison had a eureka moment: a mirror. If the lens focused its image onto a small, angled mirror, and the mirror was placed just between the painter’s eye and the canvas, by glancing back and forth he could copy that bit of image until the color and tone precisely matched the reflected bit of reality.’

Good Vermeer page here for a refresher on the Dutch master.

Penn & Teller helped make a documentary which has gotten good reviews, entitled ‘Tim’s Vermeer.

Perhaps only the Girl With The Pearl Earring knows for sure if the painter used such a technique:

Interesting quotation from Quora, on Richard Feynman’s discussion of light in ‘QED: The Strange Theory Of Light And Matter’:

‘Mirrors and pools of water work pretty much the same way. Light interacts with electrons on the surface. Under the laws of quantum mechanics, each photon interacts with ALL of the electrons on the surface, and the net result is the sum of all possible pathways. If the surface is perfectly smooth, then most of the pathways cancel each other out, except for the one where the angle of incidence equals the angle of reflection. ‘

Click through for the illustrations to help explain Feynman’s theory, which fascinated me when I first came across it; much as I understand of it.

Have you ever seen sunlight reflecting off a body of water from a few thousand feet up in a plane?  A rainbow in a puddle with some oil in it?  A laser reflecting off a smooth surface like a mirror?

Venus & Enceladus-A Few Humble Links

Phosphine gas could still be produced by some yet unknown non-living process, but it’s an interesting, and potentially important, find.

From Nature:

Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic. Here we report the apparent presence of phosphine (PH3) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms.

Despite being a near twin in size to Earth-mass and gravity, Venus spins too slowly for an electro-magnetic dynamo to create a EM field, enveloping and protecting the planet. With ninety times the surface pressure of Earth, and temperatures up to nine-hundred degrees Farenheit, to say it would be hellish would be an understatement.

Yet, it once harbored liquid water oceans, and maybe, just maybe, some kind of microbial life has migrated up into the fast-moving clouds. Click through for a visual.

Next to Enceledaus, a tiny moon being warped by Saturn, this is probably the most important indicator of extra-terrestial life going right now:

Step By Step-Some Humble Space Links

Frank Drake brings some realism to the S.E.T.I. debate.  The space-time distances are a huge hurdle, and the challenges of becoming a spacefaring civilization make the journey to nearby star systems fairly impractical at the moment.

The less evidence and fewer data points there are, the more rampant the speculation, inventive the Sci-Fi imaginings, and important the foundation to create such new fields of knowledge.

There’s been an explosion of private entrepreneurship and NASA partnership lately (loosened regulations and better incentives) to help get cargo (things and people) into space much more cheaply than before.

What’s it like to be on a spacewalk?  In some ways, pretty normal and pretty not normal, apparently: Just pace yourself, focus, and get the job done in an unwieldy suit while you hover between everything you’ve ever known and an incomprensible abyss.

In addition to recent rapid advances in ‘seeing’ with radio waves, gravity waves and light, and we’ve got better tools to get a little further out into our own neighborhood.

This means we could find out if we can find some life on Mars (methane spikes), Jupiter’s icy moon Europa and Saturn’s icy moon Enceladus:

Via A Reader-Two Oumuamua Links

Via a reader:  Hey, I’m probably not even an amateur.

Oumuamua’s Geometry Could Be More Extreme Than Previously Inferred

Recently, a visitor from beyond our solar sytem passed pretty closely to Earth.

With the observed and limited data, Oumuamua was clearly anomalous.  It likely had a 10/1 length to width ratio and was reflecting a lot of light, data which suggests a wobbling oblong or something nearly pancake-shaped (perhaps containing iron or other metals because it’s more reflective of the red, longer wavelengths on the visible light spectrum and it’s got to be of durable enough material to be so thin while surviving the roughness of interstellar space).

Our solar system is a fairly flat disk which is moving in relation to other star systems, all of which are traveling very quickly relative to Oumuamua, which was relatively stationary to these other systems when it came in at an angle to ours; speeding up again on its way out (perhaps not due to outgassing).

Dr. Avi Loeb has been working on lightsails, or thinking about how a civilization might travel and explore space and/or create something like a message in a bottle.   Below, he is interviewed on Event Horizon.

His not-ruled-out hypothesis will probably attract some UFO and alien public interest, but it seems, in my limited understanding, that as an anomaly, this is a discussion with a first-rate astronomer performing an interesting exercise in taking past experience, current knowledge and conventional explanations to their limits in trying to creatively identify something new.

It’s a big universe out there after all, and we’re just starting to get some better tools with which to view and understand it:

Robert Zubrin At The New Atlantis-‘Colonizing Mars: A Critique Of The SpaceX Interplanetary Transport System’Stephen Hawking In Cosmos: Some Reasons Why We Should Continue Space Exploration

Via A Reader: Ocean Worlds-Cassini Mission Findings Video

Here’s my brief layperson’s summary after watching: 

Both moons Enceladus (Saturn) and Europa (Jupiter) demonstrate evidence of huge oceans of liquid water protected by thick, icy crusts.  The Cassini probe passed through water plumes emanating high above Enceladus’ icy crust.  This water has been forced out of four long, deep cracks in the surface.

After analysis, the folks in the video above have discovered many chemicals within these Enceladus geysers (ammonia, carbon dioxide) but most importantly:  Hydrogen they think might be coming from hydro-thermal vents on the rocky, ocean floor of Enceladus.

Or at least, with the current evidence and knowledge, this is a very plausible scenario.

So, there’s life on Earth without sunlight, deep on the ocean floors, near hydro-thermal vents where this process produces energy enough to sustain weird life forms we didn’t know existed before very recently.

There’s water geysering out of Europa’s icy crust from its ocean floor below.

There’s potentially time + interesting life-sustaining geochemistry + energy + a protected environment on both of these ocean worlds…so…hey….

There may be something really worth finding down there.

Next up:  Sending better instruments to cruise through Europa’s geysers:

Repost-Roger Scruton At The WSJ: ‘Memo To Hawking: There’s Still Room For God’

Full post here.  (link may not last)

Perhaps Hawking is guilty of a little hubris in weighing in with such certitude on the God question?

Here’s a quote of his Hawking’s posted previously:

“His [Kant’s}argument for the thesis was that if the universe did not have a beginning, there would be an infinite period of time before any event, which he considered absurd.  The argument for the antithesis was that if the universe had a beginning, there would be an infinite period of time before it, so why should the universe begin at any one particular time?  In fact, his cases for both the thesis and the antithesis are really the same argument.  They are both based on his unspoken assumption that time continues back forever, whether or not the universe had existed forever.

-Stephen Hawking-A Brief History of Time

Not so much that time continues back forever, but that it’s impossible to conceive of a point outside of time.  Kant wished to argue that both time and space are not necessarily inherent characteristics of the universe (or any object at all…especially those objects with which we have no direct experience, like a black hole, though according to Kant we can have knowledge of objects) but rather time and space are part of our onboard apparatus, and preconditions for us have intelligible experience in the first place (unlike as is assumed in calculus, for example).  He constructed a vast metaphysics to make his point in the hopes of putting metaphysics on the same ground as the sciences (the Enlightenment was going strong around him, and he latched onto Newton’s laws especially).  It’s questionable as to whether or not he succeeded, but fascinating to think about nonetheless.

Death From Above-Good Reads From An Emailer-The 1993 Galeras Eruption

The Galeras volcano is in Colombia, and on a fateful day in 1993, it caught many scientists and tourists milling around its crater-rim by surprise with a little mini-eruption. I, too, remember reading the horrific accounts:

“I heard this huge boom, and then rocks the size of televisions started falling around us,” recalled Dr. Andrew McFarlane, a geologist at Florida International University who had got beyond the crater. Dr. McFarlane suffered a broken foot, bruises on his legs and badly burned hands from climbing over burning rocks.

Dr. Williams, fleeing the crater’s rim, pounded by flying rocks, ran as far as he could down the volcanic slope before his broken legs gave way. He took shelter from the weakening eruption behind large rocks. After an hour, a second volcanic blast hurled aloft new boulders that he successfully dodged.’

Dr. Stanley Williams led the party that day, and wrote a book entitled ‘Surviving Galeras‘ in its wake about continuing to press-on despite the tragedy.  Excerpt from his book here.  Fascinating reading.

Our emailer points out that a Victoria Bruce charged Williams with a high degree of hubris in her book ‘No Apparent Danger.’ More here.  There’s some drama involved.

Remarkably, like the predictability of extreme weather events, understanding of what helps cause volcanic eruptions is getting much better due to the work of vulcanologists everywhere.

————-

*As a side note…I remember standing across from the Mt. St Helens crater at the Johnston Ridge Observatory, witnessing the scope of destruction some 30 years on, feeling a sense of awe, fascination, a desire for more knowledge, mixed with fear and continuing thoughts at my own sudden smallness and cosmic insignificance when measured against such forces. It can be humbling.

***My uncle tells a story about passing north on I-5 over the Toutle River bridge some days afterwards, and seeing a horse carcass, upright and stuck in the volcanic mud and ash-flow that flowed down from the mountain.

That image has stuck with me.

I found a few Flickr photos of debris in that area.

From IBTimes Via Youtube: ‘NASA Mars Rover Finds Evidence Of Lake’

—————————

It looks like Gale Crater has its advantages.

Research papers here. A summary of some of what’s been found so far:

‘Research suggests habitable conditions in the Yellowknife Bay area may have persisted for millions to tens of millions of years. During that time rivers and lakes probably appeared and disappeared. Even when the surface was dry, the subsurface likely was wet, as indicated by mineral veins deposited by underground water into fractures in the rock. The thickness of observed and inferred tiers of rock layers provides the basis for estimating long duration, and the discovery of a mineral energy source for underground microbes favors habitability throughout.’

You can also watch a 12/05/13 press briefing from JPL discussing those papers above.  These rocks are much newer than the older wet period theorized.

They’re more focused on the search for organic carbon, now, within the environments they’ve discovered.

—————–

From what I’ve learned as a layman:

-Curiosity isn’t necessarily looking for life, but it’s looking for the conditions that make life possible here on Earth with its 10 instruments, such as trying to determine the origins of the methane on Mars’s surface by being better able to analyze the kind of carbon (12 or 14) in the atmosphere to find its source.  It’s also much better able to look for amino acids (the building blocks of life on Earth) and better able to analyze the rock and crystal samples it picks up.  It’s got a cool laser. It’s about the size of a Mini-Cooper.

-Unlike Earth with its dynamic interior and tectonic plates, relatively strong magnetic field, thick and dynamic atmosphere etc., Mars is a bit like a time capsule.   With just over 50% the diameter of Earth, about 38% the gravity, and  less than 1% the atmosphere we’ll be able to get a much better picture of what happened during the formation of our solar system about 4 1/2 billion years ago as it’s much less disturbed.  The trip up the rock face in Gale Crater over the next few years is like a trip back through time.  What happened to Mars?  Did the Earth and Mars have common experiences?

Some more Mars facts.

No methane on Mars, so that rules out the certain kinds of microbial life hoped for.  There is water on the surface, in the soil. at about 2%, which is good for colonial prospects.  It probably had liquid water in the past, but that is thought to have been billions of years ago.  A lot of evidence points to ancient Mars and current Mars being very different.
———————
So, what about a more human problem that interests the libertarian-minded?
——————–
The problem is that over time, human organizations succumb to decay, bad incentives, and get weighed down by their own internal politics, increasing layers of bureaucracy, and regulations.  They can end-up no longer boldly and creatively solving the problems they were designed to solve, becoming risk-averse and losing their spirit of innovation and flexibility to free-up the top talent.  You can put more and more money in, but get less and less in return.  In fact, I’d argue along with many others that we’re in a period of American life where many other bureaucracies and government agencies may have also reached that point.  Such is my road-map.
———————
After the terrible Challenger explosion in 1986, Richard Feynman was included on an independent panel to find out what went wrong.  He discovered a profound difference between engineers’ and managements’ probability estimates for number of flights without failure.  One potential (and very important) reason that a system-ending failure can go unnoticed is the tendency of managers to believe top-down explanations.

It’s vintage Feynman, inconoclastic, penetrating and brilliant:

“for whatever purpose, be it for internal or external consumption, the management of NASA exaggerates the reliability of its product, to the point of fantasy.”

“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

Watch Robert Zubrin and other Mars Undergrounders pursue their quest despite NASA at times, but ultimately benefitting from collaboration with NASA engineers’ experience and insight, giving a boost to this deepest of human dreams:  the next frontier.  A colony on Mars.

We can do this, and it will be both like and unlike anything we’ve ever done before.

Thanks to a reader for the link.

Video taken by a local resident and Bad Astronomy blogger familiar with the area.  Remember, floods kill more people than any other natural disaster.  The energy the water carries is deceptively powerful.   Safe places can become very unsafe, very quickly.  Once you’re swept away, that’s usually the end of you.

This is probably a 50 or 100 year flood, with some areas in the foothills receiving as much as 8 inches of rain in a few hours.   The area’s also had fires recently, causing less soil absorption so all that water flows down and picks up an especially nasty mix at the front end.  Thoughts and prayers to the families of those lost and/or missing.

National Weather Service statement here.

In the mountains, it doesn’t always have to rain where you are for flash flooding to occur.  Avoid low places and arroyos.  Know your terrain and stay aware of the weather.  Fascinating video of rainwater and debris flow making its way into washes in southern Utah.  Don’t try this at home:

If you have an hour, the drilling team gives a presentation and a Q and A. They explain the significance of the first non-Earth drilling.

They’ve driven the Rover over to a flat area of rocks they call ‘John Klein,’ in a depressed region called ‘Yellowknife Bay,’ beyond Glenelg which was originally a target point from the landing site.  There’s a group of likely fine-grained (siltstone or mudstone?) rocks on the Martian ground.  They’ve photographed white veins in the rocks amongst other features, and used the ChemCam to determine the veins are probably a calcium sulfate, which forms on Earth usually due to water percolating through rocks, but they’re still doing analysis.

They’re now using the drill for the first time, doing a test drill of 2 centimeters, and then drilled 6 centimeters down into these flat ‘river’-looking rocks in John Klein.  The Rover scooped up the material and it’s gray in color,  as at the surface has been exposed to iron oxidation.

You can download these photos or view them a slideshow, and the Rover team keeps updating them with each new tool they use and each new location they move the Rover.  You can track the whole mission that way in photos with captions explaining what’s going on.

Here’s animation of how the drill works (follow that link for all video updates).

They’ve made a wind map of Gale Crater based on the data received, and there are possibly dustless dust-devils, or convective vortices that occur around noon of a Mars day passing over the Rover.  The Rover has stopped at a place called Rocknest, and from this article:

‘Scientists theorize that in Mars’ distant past its environment may have been quite different, with persistent water and a thicker atmosphere. NASA’s Mars Atmosphere and Volatile Evolution, or MAVEN, mission will investigate possible losses from the upper atmosphere when it arrives at Mars in 2014.

With these initial sniffs of Martian atmosphere, SAM also made the most sensitive measurements ever to search for methane gas on Mars. Preliminary results reveal little to no methane. Methane is of interest as a simple precursor chemical for life. On Earth, it can be produced by either biological or non-biological processes.

Methane has been difficult to detect from Earth or the current generation of Mars orbiters because the gas exists on Mars only in traces, if at all.’

Still driving towards Mt. Sharp.  Some cool pics in slideshow format.  Link to NASA videos.

From NASA’s Mars Science Laboratory: ‘NASA Rover Finds Old Streambed On Martian Surface’

Full piece here.

The first real ‘direct’ observation of water:

“From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep,” said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. “Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we’re actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it.”

Apparently, it’s sedimentary conglomerate.  Rounded rocks smoothed by water and deposited in a cement like structure, which is now jutting above the surface as it lays in a large alluvial fan bed.  Comparison photo from Chile, back on Earth, of what appears to be a similar phenomenon.  The Rover is still headed towards Glenelg.

We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.”

They’re still going over the 2012 data, but an apparent triumph for the Standard Model and the structure being built atop 20th century physics.

Via The Mars Science Laboratory At NASA: ”Mount Sharp’ On Mars Links Geology’s Past And Future’

Full post here.

Mt. Sharp sits in Gale Crater, where Curiosity is headed.

“Mount Sharp is the only place we can currently access on Mars where we can investigate this transition in one stratigraphic sequence,” said Caltech’s John Grotzinger, chief scientist for the Mars Science Laboratory. “The hope of this mission is to find evidence of a habitable environment; the promise is to get the story of an important environmental breakpoint in the deep history of the planet. This transition likely occurred billions of years ago — maybe even predating the oldest well-preserved rocks on Earth.’

The water find is less probable.  Expected landing date is August 6th, 2012.  Let’s hope it goes well.

From PhysOrg: ‘New Research On Japanese Quake Ominous For Pacific Northwest’

Full piece here.

‘The longest record for a subduction zone is from Cascadia, where scientists have linked buried marshes and submarine landslides with a series of about 22 megaquake quakes going back 10,000 years. The time between quakes ranges from 200 to 1,000 years, with an average of about 500 years’

Related On This Site:  The last big Cascadia subduction zone earthquake likely occurred on Jan 27th, 1700, at magnitude 9.0. The article suggests an occurence anywhere from 300-350 year intervals up to 400-600 year average intervals (new research suggests the former). It’s just over 311 years and counting.

Repost-‘More On “Dark Flow” From Space.com’

Full article here.

“Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can’t be explained by any of the known gravitational forces in the observable universe”

It seems to be caused by something more powerful than a black hole…a leftover bubble from the big bang, further away from us than we could ever see?…

“In fact there’s a fundamental limit to how much of the universe we could ever observe, no matter how advanced our visual instruments.”

“There may be parts of the universe that are farther away…but we can’t see farther than light could travel over the entire age of the universe”

How do you explain that many thousands of galaxies are moving rapidly away from us toward points unseen, seeming to contradict the general expansion of the universe?

From The New Scientist: ‘Giant Crack Formed In Just Days’

Full article here.

Thought this might be of some interest:

“The crack is the surface component of a continental rift forming as the Arabian and African plates drift away from one another. It began to open up in September 2005, when a volcano at the northern end of the rift, called Dabbahu, erupted.”

And it happened in a few days, apparently.

“…Ebinger says it could continue to widen and lengthen. “As the plates keep spreading apart, it will end up looking like the Red Sea,”‘

Possibly in 4 million years.

From Youtube: Lite-Brite Supernova

This won the youtube phylm prize (very prestigious).  Most astronomers believe that all elements other than hydrogen and helium come from supernovae.  So, in many senses, we are stardust.

Much of this understanding springs from the work of Subrahmanyan Chandrasekar in the 1930’s and the Chandrasekar limit (wikipedia). From wikipedia:

“A critical situation arises when iron accumulates in the core, since iron nuclei are incapable of generating further energy through fusion…”

“For more massive stars, electron degeneracy pressure will not keep the iron core from collapsing to very great density, leading to formation of a neutron star, black hole, or, speculatively, a quark star.”

Or the star can undergo a supernova explosion.

From Boston.com: Three Mystery Waves In Maine

Full Boston.com post here.

“In 15 minutes, the water rose 12 feet, then receded. And then it happened again. It occurred three times, she said, each time ripping apart docks and splitting wooden pilings.”

Spooky.  The article mentions 3 possible causes:

1.   Land movement-A landslide underwater by seismic disturbance or more likely by a land slump.  The slump could be caused by strong storm conditions that have stirred the water.  Perhaps even a methane decompression (land movement caused by gas) as the article mentions…however no seismic disturbances were measured.

2.  Wind movement-During large storms (and ocassionally not) a lot of wind blowing over a lot of water can generate high wave action.  The article mentions a squall line surge.    A brief explanation from The Deadliest Catch here about wind, current and how land underneath can effect wave action.

Brief you tube video explaining the difference between transverse and longitudinal waves here.  It gets more and more abstract.

3.  Tides-Due mostly to land form, tidal piles of water fill Maine’s harbors creating extreme difference between high and low tide.  This is not so far from the Bay Of Fundy, which has some of the highest tidal action on earth.  Stop-motion video of those tides here:

Tornadoes! Some Links

With so many deadly tornadoes in the news lately, I thought I’d post a few links:

Here’s a link to the How Stuff Works tornado page.

The Tornado Project Online. (Affiliated with How Stuff Works, lots of top-ten lists etc…)

-How to make a tornado box for a science fair.

-Is it a vortex of rising, warm and moist air or cool air dropping downward?   Good models here.  A horizontal column of rotating air that gets lifted with the rising air in the formation of a storm?

-The Red Cross Tornado Preparedness Page.

-You’ve got to check out Tornadovideos.net.

A swedish guy has a small tornado drop down in front of his car (1:15 or so, cool video)A dust-devil here.  If you have time and are a real weather geek, the formation of a supercell here.
