What could possibly be more awesome than a TORNADO MADE OF FIRE?!? Not much. This is a spectacular natural phenomenon that occurs in wildfires. It’s the same atmospheric process that causes dust devils- the difference here is that the strong updraft is from the heat of the fire, so it’s much more intense than a normal dust devil. The hot air rises rapidly and the surrounding winds happen to be flowing into the updraft at just the right angles so that the rising column of air gets a twist. From there the law of conservation of angular momentum takes over and the vortex becomes self-sustaining. This one was captured recently in Australia.

Also from the department of TOTALLY AWESOME: Warp Drives (like the ones they used in Star Trek) may actually be much closer to reality than ever thought. NASA physicist Dr. Harold White has recently done some tweaking of the theoretical design of the famous Alcubierre Warp Drive, originally proposed in 1994 by physicist Miguel Alcubierre. The original design, while theoretically possible, was completely impractical because it required more energy than a human mind can comprehend. But with Dr. White’s tweaks, the amount of energy required to run this thing suddenly became more plausible. Essentially the ship would be able to travel much faster than light, without actually traveling faster than light. It does this by literally compressing a region of space-time ahead of it and expanding a region behind it. The ship itself is in a bubble in which it never breaks the speed of light relative to the space-time it’s in. Think of it like surfing a wave of space-time. Granted, the amount of energy require to run the Warp Drive is still roughly equivalent to 1.5 million Hiroshima bombs, but with a little antimatter (about 500 kilograms) that number is not out of reach. The problem is that the idea hasn’t been tested in real life. So Dr. White and his team are currently attempting to actually warp space-time on a microscopic scale in their lab. Take a moment to digest that. Right now, we are attempting to warp space-time in a lab. It doesn’t get much more awesome than that. For more info on how the drive actually works check out this article on Extreme Tech or this article on Discovery News.

It may take many more days before NWS survey teams can finish their assessment of the damage from the April 27th tornado outbreak, but being the weather nerd that I am, I want to go ahead and share a collection of links where you can find preliminary reports on the tracks and intensities of some of the many twisters that touched down. Note that there is at least one EF-5 (the highest intensity with winds over 200 mph) tornado confirmed, and there could be more upgraded to that status as more damaged is inspected. NWS Memphis survey– covering parts of northern Mississippi. NWS Jackson, MS survey. NWS Hunstville, AL survey. NWS Morristown, TN survey. And finally, this graphic from the NWS Birmingham, AL survey. The most complete graphic I’ve seen:

So that’s the bad. Please make a donation to the American Red Cross or any other legitimate organization providing relief for those devastated by this natural disaster. Now for some good things to lighten the mood.

I will call the news of Osama bin Laden’s assassination good, but I certainly will never rejoice the death of any human being. While I am relieved somewhat, and do feel that justice has been done, I’m quite certain that the assassination itself as well as the celebrations will only give the rest of al-Qaeda even more reason to attack the US and its allies.

In even better and much much much lighter news, Moustache May has begun its final year of activity. I participated back in 2008 and am doing so again this year. Due to some very important meetings happening last week at my work, I was unable to start my stache until Friday, so I’m basically starting with a clean slate. Right now I look utterly creepy but hopefully we’ll get past that stage very soon as it fills in.

I came across this absolutely amazing new music video for the Supermen Lovers’ track “Take A Chance” and decided that it was the best thing to end this post with. Enjoy. (Via Too Many Sebastians)

So I’m thinking that some Fridays I’m gonna steal NPR’s “Science Friday” idea and write a post debunking some popular myths. Not gonna happen every Friday, but I’m gonna make a pointed effort to do it somewhat often.

Today we’ll tackle the myth about water spinning in opposite directions down the drain in the northern and southern hemispheres. This is simply not true at all. While large-scale weather systems do indeed follow this pattern due to a phenomenon called the Coriolis Effect, water going down a drain does not. Minute things such as imperfections in the angle at which a basin was installed, inconsistencies in the surface or shape of the basin, and any residual motion in the water itself are what determine the direction the water rotates when drained. Once the water begins to drain, the conservation of angular momentum takes over and any hint of rotational motion in the water, whether clockwise or counter-clockwise, gets amplified as it moves toward the drain, creating a vortex. This is the same law of physics that causes tornadoes and dust devils to behave the way they do. The classic explanation for this concept is the spinning ice skater. As he/she moves her limbs closer to their body the conservation of angular momentum forces their rotational speed to increase. They can then move their limbs further away and they will slow down again. So no, no matter what you’ve heard, water does NOT always drain counter-clockwise in the northern hemisphere and clockwise in the southern. That being said, experiments have been done that show the Coriolis Effect can be seen in draining water IF AND ONLY IF all other forces are completely removed. A large and absolutely perfect cylinder-shaped container with one very small hole exactly in the center was filled with water and allowed to sit untouched for 24 hours to allow any residual motion in the water to die out. The container was perfectly balanced with extreme precision. The plug in the hole was then carefully removed and the water did eventually start rotating counter-clockwise, and continued to do so when the experiment was repeated. BUT clearly this only happens in extremely controlled conditions. In your sink or toilet, a myriad of other forces are orders of magnitude stronger and completely overwhelm the minute effect of the Earth’s rotation. Snopes has a decent debunking of this myth as well.

Tornadoes are different. I was asked about this yesterday, in the wake of the massive tornado outbreak on Wednesday. The Coriolis Effect does influence the direction tornadoes spin, but in a more indirect way. There have, in fact, been clockwise (anticyclonic) tornadoes documented in many cases in the U.S. There have even been a few storms that dropped multiple tornadoes, both cyclonic and anticyclonic, at the SAME TIME. As I said earlier, the Coriolis Effect is what causes large-scale weather systems such as hurricanes, low pressure systems, and high pressure systems to rotate the way they do. Low pressure systems and hurricanes always rotate counter-clockwise in the northern hemisphere and clockwise in the southern. The opposite is true for high pressure (clear weather) systems. The storms which produces tornadoes are always associated with a large-scale low pressure system. The Coriolis Effect determines the rotation of that large-scale system, which in turn has an indirect influence on the structure of the supercell thunderstorms which spawn tornadoes. Tornadoes are far, far more common in the U.S. than anywhere else in the world, and because the warm moist air which “feeds” these storms at the surface is moving in from the southeast, and the cooler, drier air aloft is moving in from the northwest, that setup naturally lends itself to counter-clockwise rotation, hence most but not all tornadoes in the U.S. spin counter-clockwise. This illustration from NOAA’s National Severe Storms Laboratory shows the inner workings of a tornadic storm quite well:

The U.S. Department of Energy’s Office of Science Education has a website called NEWTON, with a forum of sorts called “ask a scientist.” This very question regarding the rotation of tornadoes was asked, and I found this particular response quite helpful:

At least the great majority of tornadoes rotate counterclockwise (as do all low-pressure systems) in the northern hemisphere, and clockwise in the southern hemisphere, for the reason (coriolis force) given by Eric Peterson in response #1. But occasionally, it would seem, northern hemisphere tornadoes do rotate clockwise: S. Flora’s book “Tornadoes of the United States” cites an 1890 article in the American Meteorological Journal. Its author, a J.P. Finley, states that, of 550 American tornadoes he studied, 29 were deemed to have rotated clockwise. I have not been able to find any “modern” study of this question. But I believe it could be true. The region of swirling air that contracts to become the tornado is not itself large enough in extent to have its rotation dictated by the coriolis force; rather, it “inherits” this tendency from the great masses of air whose movement sets the stage for the storms and any associated tornadoes. If the study cited is correct and representative, on occasion the direction of rotation is set by some other factor, perhaps the topography in the area where the tornado forms, for example.

So there you have it. I won’t have as much time every week to write up a post this in-depth, so don’t expect this every Friday, but I’ll do my best.

Eating lunch with the Darlins in the Bronx.

So I’m back! It was a blast and I’d do it all again in heartbeat. I don’t have time to give a full rundown, but quite possibly the most memorable moment was realizing that a tornado was hitting Brooklyn while Those Darlins were soundchecking in Bowery Ballroom. Here’s the official weather report from the NWS. Needless to say, tornadoes are pretty rare in NYC. Thankfully we were in Manhattan while all this was happening. Those Darlins have some great new songs on their new record, and their setlist for this tour is mostly those new songs, peppered with the favs from their debut, and the free single “Nightjogger” which you can download at the Nashville Cream. Basically they’ve taken on a bit more of a pure rock & roll character, and drummer “Sheriff” Linwood Regansburg has taken on a much more prominent role in the songwriting, and even sings on one of the new songs, though they’re not yet playing that song live. Stay tuned for more on them and more on the results of my photo documentary project.

Meanwhile, here are some awesome things I came across while catching up on all my RSS feeds:

Vaccines absolutely, beyond a shadow of a doubt, do NOT cause autism. A new study explored every possible way that thimerosal containing vaccines (TCVs) could be linked to autism and there was none. Absolutely no connection whatsoever; the same findings as the many other studies that have been done to investigate the claims of the anti-vax crowd. In fact, the result hinted that the administration of TCVs between birth and 7 months may actually reduce the risk of autism. It’s very simple, get your kids vaccinated! If you don’t, you are a threat to public health. Vaccines are one of mankind’s greatest scientific breakthroughs and have saved countless lives. There will always be a miniscule (and utterly negligible) risk of a bizarre allergic reaction or other complication, as there is with any medication or vaccine, but that risk is far, far, FAR outweighed by the benefits. And those risks have now been proven once and for all NOT to include autism.

A pair of astronomers have made an official prediction that the discovery of the first truly earth-like exoplanet will happen in less than a year– May of 2011. They used a well-known methodology called Scientometrics to make this prediction. I’d venture to say that to me, nothing in the field of astronomy, or even science in general, is more exciting than the very likely possibility of life on other planets. The discovery of the first true earth twin is a major step in that path. I really hope this prediction comes true.

Five awesome facts about NASA’s next robotic mission to Mars, the Mars Science Laboratory (a.k.a. Curiosity) which will launch in late 2011.

23 amazing photographs from the 1940s and 50s of nuclear bomb tests conducted by the US Military. This New York Times photos series is utterly fascinating, mainly because of images 5 through 7. Most of us have seen plenty of images of the mushroom clouds created by nuclear blasts, but those 3 images are unlike anything I’ve ever seen before. They were taken with a super high-speed camera and literally captured the blast at the very instant the explosion began. If I saw this image out of context I would probably think it was a microscope image of some sort of virus. The amazing irony here is that both a virus and an atomic bomb are incredibly destructive, yet in such completely different ways.

The actual scale of the observable universe, from the smallest possible thing the largest possible thing, is utterly impossible for the human mind to comprehend. Mathematicians came up with the concept of “orders of magnitude” to help with this, but I say it’s still impossible for any human to really grasp. But this fun little interactive Flash animation is pretty cool way of displaying the concept. (Via Dr. Neil deGrasse Tyson’s Twitter)

Weekend shows & weather

April 23, 2010

This weekend is actually pretty good in terms of live music in Nashville. Here’s what’s on my radar:

The biggest story tonight and tomorrow is probably Rites of Spring at Vanderbilt, featuring the awesome one-two punch of Phoenix and Passion Pit. The full lineup is at the RoS website, but the only bands I’m even remotely interested in seeing are those two, and maybe Two Door Cinema Club. I will be there taking pics for the Scene as usual.

Friday: If outdoors festivals aren’t your thing, Chicken Ranch Records out of Austin, TX is doing a badass showcase at the Basement featuring The Clutters, We Were The States, Tiger Tiger, and Jimmy Duke & the Riot.

Saturday: If outdoor festivals aren’t your thing and afterparties are, you’ll want to head to 12th & Porter where the weekly Y2K DJs Coach and Hands off Sam will be joined by none other than members of Passion Pit, who will have (or not, depending on the weather) played Rites of Spring earlier that evening. DJ Potamus is also on the bill. I’ve heard nothing but good things about Passion Pit’s DJ sets- they did at least a few of them at SXSW this year.

Sunday: Peelander-Z w/ Tim Chad and Sherry & The Man Power at Exit/In. I saw Peelander-Z there a couple years ago and it was a blast. The bass player was literally hanging upside-down from the balcony. Just be prepared for some major crowd participation if you go.

Another big story this weekend is the weather. As you can see from the NWS severe weather outlook to the right, we’re in the “moderate risk” category for severe storms on saturday. The current thinking is that some storms will beigin to roll in very late tonight, sometime between 11pm and 3am, and hopefully not drenching tonight’s Rites of Spring festivities. Then the real action will start up saturday morning and basically be a threat all day long, into the evening. This is not just a few storms with a little hail and some wind, there is also a good possibility of tornadoes, and that’s why I have a strong feeling much of saturday’s Rites activities will end up getting canceled altogether. I can only hope for their sake that the threat passes by the evening AND that no damage is done to the stage/equipment so that the headliners can at least still play.

Important weather things to remember for saturday: The Storm Prediction Center in Oklahoma issues severe weather watches. A watch is for a large area of land and means that conditions are favorable for severe weather to occur, but it is not an immediate threat. Our local National Weather Service office issues severe weather warnings. A warning is usually for a county or even just a city area and means that severe weather is actually occurring and will hit your area soon, so take cover. There’s always confusion on Vanderbilt’s campus regarding the on-campus vs. the downtown Nashville tornado sirens as well. Here’s how it works: the downtown Nashville siren goes off if there is a tornado warning issued for anywhere in Davidson County. The Vandy campus siren only goes off if a tornado warning is issued that specifically includes downtown Nashville. Thus, sometimes the downtown siren will go off and the Vandy campus one won’t (example: a warning issued for SE Davidson Co./LaVergne), and frankly it confuses the hell out of people on the Vandy campus. But that’s how it works.

Please be safe and heed all warnings this weekend!

Weekend/A-Trak video

April 2, 2010

This weekend has a nice offering of musical goodness if you’re in Nashville. As of now I don’t have any specific plans other than Saturday, but first here’s tonight’s items of interest-

Heartbeater, Trophy Wives, The Goldroom (the Goldroom had to cancel), Waxeater @ The End. Heartbeater is becoming a fairly well-established live act in town, and they’re currently working on a debut album.

Majestico, My Tyger @ The Basement. Majestico is simply awesome, and though I’ve only seen My Tyger once at an 8 off 8th, they don’t disappoint, either.

Finally, my likely destination will be the Exit/In, where Wax Fang, How I Became the Bomb, and the Non-Commissioned Officers are playing their rescheduled show from Jan. (It was snowed out due to Snowmageddon ’10.) I also hear that Bawston Sean will be DJing before and between bands. A good time for sure!

For Saturday-

Fever Queen, How Cozy!, The Grayces, and Hanzelle @ The End. This is a benefit for the Tennessee Teens Rock Camp, which is a new co-ed offshoot of the now famous Southern Girls Rock & Roll Camp. Seriously, if the fact that Fever Queen is a new Cortney Tidwell side-project isn’t enough to get you there, then surely you’ll go and pay the meager $5 cover/donation simply to support such an awesome program. And if you are around and able this summer, I also highly suggest volunteering for one or the other (or both!). You don’t have to teach an instrument or workshop either- there are plenty of other non-skill-requiring volunteer positions.

I will not be able to make it to this show as I’m attending someone’s private birthday shindig. But that’s okay, because I will likely be volunteering for TNTRC this summer.

A couple of random links of interest-

Fool’s Gold blog posted a pretty cool video/interview snippet of DJ A-Trak, as well as another video about his new project with Blink-182 drummer Travis Barker. It sounds totally off the wall and random, but it’s surprisingly good. Just be open minded and check it out…

I didn’t have time to find enough science-y links/content to fill it’s own post, so here’s your random science-related tidbit of the day: Here’s a video of the world’s largest artificial tornado, created with the ventilation system inside the Mercedes-Benz Museum in Germany. I think vortices are among the most beautiful things in nature, and have always been completely mesmerized by them. (Via Kottke.org and BLDGBLOG)

Have a great weekend!

The fine folks over at Nashvillest have attempted to top their famous reader-submitted “CMA Bingo” game this year by having a submission contest for this year’s. By the time you read this the contest will have closed, but look on Nashvillest.com tomorrow to see the winner. I don’t know if anyone can top last year’s though:

Some quick science tidbits before I get into my “rant”….

The Japanese Kayuga probe has been orbiting/studying the moon since 2007 and will make a controlled impact on the lunar surface today. No, it’s not landing, it’s actually going to crash into the surface at full orbital velocity. In other words, it’s going to make a crater. It’s done its duty, so might as well go out with a bang eh?

Remember when I told you about project VORTEX 2? A quick refresher- it’s a huge team of scientists that are currently chasing tornadoes out in the plains to gather data and improve on warning systems/prediction. Actually I think it ended today. But they did capture one piece of truly phenomenal footage when a twister they were filming turned/roped sideways and gave their videographer a view straight down the throat of the funnel. Check it out here. Absolutely amazing! Via Live Science.

Fair warning: I’m about to rant on something. But it’s very much worth ranting on.

As you know if you’ve read this blog before, I’m a photographer for the Nashville Scene. Last year I covered Bonnaroo for them and this year I’m doing it again, only this time my photos will be used across most of the blogs and papers owned by Village Voice Media. Photo contracts are quite commonplace at concerts involving big-name artists/bands. Bonnaroo, being the biggest festival in the country, is obviously no exception. They have a blanket contract that photographers have to sign in order to cover the festival at all. Last year its was a pretty basic contract just limiting the usage of your photos to whatever specific publication or wire service the photographer was shooting for. Without any kind of contract, legally a photographer can sell his/her images of a band or artist’s performance to any agency or news publication without a model release from the people in the photos because that is considered editorial usage, which is different from commercial usage (which requires a model release from anyone in the photo). In recent years, as the music industry has crumbled due to its unwillingness to adapt to technology, labels and artist management firms have introduced what are known as “rights-grabbing” contracts that get shoved in a photographer’s face right before they go in to photograph a show. These contracts have gotten more and more outrageous in the last few years, and this year I got my first taste of a full copyright-grabbing contract. I won’t say which artist/s I’m referring to, but suffice it to say that there are a few specific artists every year at Bonnaroo that have a separate contract than the overall festival photo contract, and they also have a restricted list of photographers who will be allowed to photograph them. This year there were 4 that did this. (So far I’ve been approved for 3 of them.) This particular artist’s contract stated that I would have to turnover the full image rights to the label, and that the images could be used only once for the specific publication I was shooting for. After that, the label would then own the images and wouldn’t have to pay me a dime for them. Furthermore, this meant that the label could then use my images in merch, promotional items, or whatever they please, and I wouldn’t get a penny of royalties or any other compensation. If I don’t sign it then I won’t be allowed to photograph the artist. Let it be known that I will certainly NOT be signing such an outrageous contract and that thankfully VV is backing me up on it. They agreed that the terms of the contract were completely unreasonable and didn’t expect me to sign it, and were fine doing without photos of said artist. It’s really pathetic that these record labels are not only screwing their artists out of money, they’re now trying to screw the photographers who cover their artists’ concerts. These people literally must have no shame or dignity. What these contracts do is essentially steal and then exploit. If you’re a music photographer, please read these contracts before you sign them. If an artist insists on such a ridiculous contract, then they are NOT WORTH YOUR TIME IN THE FIRST PLACE! And if the publication for which you’re shooting does not back you up on this, then you are working for the wrong publication, and they are not worth your time either!

Thank you and good night.

P.S. Don’t expect to see many posts on there over the next few days. I have no idea if I’ll have time to blog at all, and if I do it’ll be a very quick blurb about something crazy I witnessed.

It’s been far too long since I mentioned Zooey Deschanel on this blog. Thus I bring to you a new cotton advertisement featuring the beloved actress/songstress, via Videogum:

One of the bands that literally shaped my formative years was Weezer. Subsequently, I am also a fan of former Weezer bassist Matt Sharp’s project The Rentals. They formed in 1994 and released two albums, but had a large gap in activity until about 2 years ago when they came out with a new EP and did a couple of tours with a revamped lineup. It wasn’t anything to write home about, but getting to see them live twice was totally rad. I saw them in Atlanta with Ozma, and again here in Nashville at City Hall (now Urban Outfitters). See more pics from that show on my flickr here. RCRD LBL features a download from the first installment of their new multi-media project called Songs About Time. The project also includes a photo series by Matt and a bunch of short films.

Speaking of RCRD LBL, I noticed that they also have a download/blurb about local star-tangled indie rock lady Cortney Tidwell. It’s a track called “17 Horses” from her upcoming album Boys. (The download page incorrectly states that the track is from her previous album.)

SNAKES ON A PLANE! IN REAL LIFE! Thanks Kelly.

Nashvillest posted a bunch of great links/ways to help victims of the Murfreesboro tornado that struck last Friday. Check it out.

This is both terrifying and fascinating. The stats for “since you started watching” really hit home. I’ve had the tab open for a good hour or so now- ~28,000 people born and ~11,500 people died. Population control will soon happen everywhere. It’s only a matter of time.

South Park may have pulled off the impossible: putting Kayne West’s ego in check. This Billboard.com article reports that last Wednesday’s episode “skewered the famously self-important rapper… painting him as a narcissistic figure so out of touch with reality he couldn’t even take a (very politically incorrect) joke.” Well done, South Park. Check out Kayne’s blog post here.

Stephen Colbert is a smart guy. The most brilliant thing he’s done recently is rally his fans to vote on an open NASA poll for the name of their next node to be added to the International Space Station. They had some suggestions- Serenity, Earthrise, etc… very typical-sounding names for stuff like that. But they had an write-in option, which Colbert exploited. The result was that the name “Colbert” won the contest for naming the node, and NASA has been scratching its head as to what to do about it ever since. Tomorrow night we’ll find out their decision in a clever way- astronaut Sunita Williams will be on the show to unveil the name. Will it really be Colbert? Only time will tell. It’ll be an interesting episode for sure…

The CIA and USAF have finally declassified a project that was based at the mysterious Area 51 base in Nevada. The LA Times interviewed 5 former employees of the facility who disclosed details on a top-secret spy plane code named OXCART. This plane allegedly has an odd shape, and was capable of flying at Mach 3. This could explain a HUGE number of the UFO sightings in that area, because according to this article there were 2,850 test flights of this thing, all conducted from Area 51. This is a bigger deal than it may seem, because up until now, the government didn’t even acknowledge that Area 51 existed. By declssifying this project they’re now admitting that it does exist. A big step forward if you ask me. I’ve always been fascinated by the place, and really want to go out there just to walk up to the signs telling you that you’ll be shot if you try to break in. I’m quite sure that there are some crazy things going on there involving technology that we haven’t even dreamed of yet, but I won’t say or believe that they’re reverse-engineering UFO’s and keeping aliens in freezers until proof of such a claim exists. Via io9.

Friday’s tornado outbreak was pretty devastating, though the vast majority of the damage was from an EF3 twister that hit nothern Murfreesboro. The official NWS survey has determined that a total of 4 tornadoes hit middle TN on friday- three EF1’s and one EF3. The report actually says “at least EF3,” so there’s a chance it may be upgraded to an EF4. One of the things that made this particular tornado so devastating was the fact that it was a multiple-vortex tornado. I will leave you with this absolutely amazing video footage shot from a tall building in Murfreesboro. (Probably the bank building.) You can easily see the smaller funnels inside the main vortex. The first few seconds are jittery but he sets the camera down and you get a long, clear look at this monster. Watch closely at about :45, 1:15, and 1:30 where you can clearly see a smaller vortex to the right of the main one.
