Hello!

I’m a student teacher right now in a ninth grade earth science class and I’d love to find more ways to involve technology in the classroom. Do you have any suggestions for iphone or ipod apps to use in a classroom at the middle school or high school level? (I’m focusing on Earth Science but all science apps are welcome).

Thanks,

Allison

Great question, Allison! Let’s dive right in by exploring my own phone. Here’s a screenshot of my “Science” apps folder on my iPhone. I have a 4S, but these should all work on any iPhone or iPod with a camera, compass, and GPS.  They’re not organized in any particular order, so I’ll just go through them from top left to bottom right.

1) Compass (Built-in) – Comes standard on new iPhones, gives heading and GPS coordinates, can be calibrated to True North or Magnetic North. Nothing too special there, but still mighty useful.

2) iHandy Carpenter ($1.99) – While you can get the basic level for free, I’ve found I really like having the extra tools available in the paid version of this app. While not strictly scientific, when the iPhone was relatively new and there were few geology apps on the market, I found a lot of utility in the different functions this app provided.

3) Basic GPS ($0.99) – I snagged this app because even though it’s redundant in giving you GPS information, it gives a bit more information than the compass or map, including UTM coordinates, exact location error (as opposed to a visual circle), altitude (hugely helpful) and altitude error. The added feature of being able to e-mail coordinates comes in handy for mapping and coordinating group projects.

4) iSeisometer (Free) – This app is really straightforward. It uses the accelerometers to provide a graphical readout of how the phone is being moved around in 3 dimensions. It’s mostly a novelty, HOWEVER, in the event of a earthquake, should you react fast enough and actually open this app, and then put it on a hard surface and record the earthquake, you can send your data (along with your GPS coordinates) to the USGS. That’s pretty neat, but unless you’re in an earthquake zone and extremely calm during a crisis, may never actually be used.

5) Convertbot ($1.99) – An app for converting things. Loads of choices, engaging interface, worth a shot if you need something more than just Google. I got it while it was being promoted for free, so I can’t speak to whether or not it’s worth the price.

6) Skeptical Science (Free) – Have you ever gotten into a frustrating argument with a climate change denier? Did you find yourself stumped by their arguments even though you knew they’re flawed? Then get this app and educate yourself. It’s pretty easy to use, and has lots of good info, whether or not anyone is convinced by your “liberal propaganda conspiracy app” is on you.

7) Geolcompass ($2.99) – This app is a digital version of an analog transit compass, e.g. a Brunton. I’ve been working on a similar app for awhile, but it hasn’t hit the app store yet. If you know what a Brunton is, you may want this app, if not, don’t stress it.

8 ) Geocompass ($0.99) – Another attempt to digitize the analog transit compass. This one has a more Spartan interface, so if you don’t care about graphics, this one may suffice. I have yet to rigorously test either to see how well they actually work, but if they work as well as the built-in compass, you should be fine.

9) Planets (Free) – This app might top the list as one I actually use on a regular basis. How often do you find yourself outside at night and a debate breaks out as to which heavenly body is a planet vs. a star? Well I have. And this app is usually how I settle the debate. Not as full-featured as Skyview Free below, but the interface on Planets is really clean and clear. You can see what’s in the sky at your location in that moment. You can also easily look up when celestial objects should be visible, which for something even for something as simple as the sun can be surprisingly handy.

10) Lambert ($2.99) – An app I have never used. I can tell it has some sort of utility for geologists, but not really the type of geology I do these days. If you do know what this app is for an how to use it, feel free to explain it to us all in the comments!

And then Cancer attacked my T-Rex pinata.

11) Skyview Free (Free -or- full-featured for $1.99) – This one has a lot in common with Planets, but I use them for totally different things. While Planets gives a lot of good information, Skyview has a far more interactive interface. Sometimes this is less convenient, sometimes more. The coolest thing, for me, is being able to chart the suns course across the sky and quickly find and identify constellations. I could see kids in the classroom having a lot of fun with this one.

12) Mendeley (Free) – My final app is really more about utility than fun. Mendeley is a program for cataloging and organizing academic PDFs. Almost every scientific article I have is uploaded to Mendeley via the desktop application and then synced to the cloud. This allows me to read articles on my iPad or access them through my phone. I almost never sit and read articles on my phone, but in a pinch when I needed something from a specific reference that wasn’t on hand, being able to quickly download it to my phone was invaluable.

BONUS APP: Kepler Explorer (Free) – This app just came out, so I haven’t had time to play with it much, but it purports to provide information based upon data retrieved by the Kepler Space Telescope, which we’ve talked about before on the show. While these may not be objects you can readily see in the night’s sky, it’s nice to know you still have the data literally at your fingertips.

So there’s my list for some handy sci-apps for your sci-class. I think gadgets like the iPhone have a huge potential as teaching tools and I’m looking forward to the day where people use these incredible devices as a way to understand the Universe rather than fire unhappy fowl at egg-stealing swine (even if I do have, and enjoy, that particular game, but you get the point). My list is by no means exhaustive, so I’m sure there will be more tasty apps to be found in the comments.

Space Chronicles: Facing the Ultimate Frontier

Written by Dr. Neil deGrasse Tyson

$26.95 / Hardcover / 384 pages

Published by W. W. Norton & Company

If I had to use one word to describe Dr. Neil deGrasse Tyson (other than the obvious “brilliant” synonyms) I’d say he’s passionate. His desire to help the public appreciate science crosses media barriers with a verve and energy unmatched by many modern agenda promoters. Space Chronicles reads like an attempt to distill and bottle some of that passion, and the ensuing cocktail is an invigorating delight sure to infuse the reader with the spirit of Dr. Tyson himself.

First, a bit about the less-than-conventional format. The book is a collection of essays, interviews, tweets, and more that have been collected from over the years. This tactic of book compilation could come across as lazy were it not clear that thought went into the final product. Pieces are not simply chronological, but more thematic explorations of various facets of the cosmic exploratory gem.

This formatting leads to some interesting trends. I found that certain points are repeated more than one would expect in a more typically produced book. I felt that the repetition helped highlight the “big picture” and made some of the more impressive statistics easier to remember and keep track of. Beyond that, the repetition could be seen as poetic, serving as a bridge to Tyson’s often Preacher-like cadence and speaking style.

The differentiation in media collected for the book also serves to break up the pace of normal reading. A chapter clearly written to be read may be followed by a page-long series of tweets then followed by a live interview, and anyone who has heard Dr. Tyson speak should hear his voice in their mind clear as day. The constant shifts in tone and style keep the book fresh and dynamic, just begging the reader to turn the page at the end of each chapter.

Space Chronicles is written for the public, not just the scientist or space enthusiast. Rather than dumb down the science for the uninitiated, Dr. Tyson successfully elevates the discourse in order to bring the reader along for the discussion instead of just talking at them. Tyson knows what gets people excited, but he also knows what is possible within the scope of financial and political reality, and he manages to balance the frontier of discovery with what is actually possible. This tactic serves to inspire as well as motivate. While your mind’s eye focuses on the cosmic perspective, your gut tells you to get working on how to actually solve the immediate problems facing our national discussion on space.

Dr. Tyson likes to remind us to “keep looking up.” I’m a paleontologist, so I almost literally have my head in the dirt looking straight down, but he’s right in that even I was inspired by space at an early age almost as much by dinosaurs. Tyson is right that we need big projects fueled by big ideas to keep science in our nation and in our world as vibrant as possible. Science relies heavily on the influx of the young motivated dreamers, and I think this book will create a few, or at least remind those who may have forgotten.

 4.5 Brachiolopes out of 5

Dear Governor Haslam,

I am writing this letter to you with the hope that you are a man of logic and reason. I don’t believe a person could achieve your status without these basic qualities, and at the very least your love of baseball serves as a testament to your fondness for statistics. I am writing you today about House Bill 0386. I doubt I am the first person to weigh in on this issue, but I would like take a moment to talk about why I think my opinion is relevant, and why this bill is ultimately detrimental to students in our home state.

I live in Nashville, where I am attending Vanderbilt University to get a Masters of Science in the department of Earth and Environmental Sciences, specifically in the field of Paleontology. And as much as my presence resides here in Music City, so too do my earliest memories. My family moved here when I was six weeks old so my dad could go to medical school, also at Vanderbilt. Some of my earliest memories are playing near the medical campus at the Dragon Park (I honestly don’t know what its official name is). Moving back to Nashville has been an unexpected joy. I love this city, and I love Tennessee, and it is out of that love that I am writing to you.

This bill is a bad idea. I’m not writing to sell you on the merits of evolution or to bash upon intelligent design. If you really want to have that discussion, I am more than happy to talk about that, but the proposed amendment to Tennessee’s educational standards is much simpler than that.

Science is not a list of facts; it is a process by which we understand that world. The process is slow and iterative, but ideally improves with every experiment and observation. With that in mind, I can comfortably admit that scientists are wrong all the time; it is part of our job. I have actually never met a group of people more willing to be wrong, because if we were right about everything there would be no new areas of the universe to explore. This means that any science teacher worth their salt should already be teaching about the scientific method in a way that explores both the successes and failures of what science has taught us about the world we inhabit.

Allowing special interests to push forward legislation that singles out particular politically-charged theories does nothing but damage the educational reputation of our state. Just this week you announced funding for new schools designed specifically to promote STEM education, but if you sign this bill you may as well give back the money because what good are schools designed to promote science in a state that disregards scientific legitimacy.

The bill states that some teachers may not feel well-versed enough in the material to comfortably teach it. This seems a call to arms to help our teachers rather than hurt our students. And this bill will hurt our students. As an educator at the college level I am often dismayed by the lack of scientific literacy in the students I encounter. These students come from all over the country and I acknowledge that this is a problem affecting more than just the Volunteer State, but you in this moment have the opportunity to take a stand. Academic freedom should not include the freedom to teach falsehoods to students, and enough freedom should already exist to allow the teaching of the most up to date and accurate science, regardless of alternatively motivated controversy.

Therefore, I implore you not to sign this bill.

If you have any other questions, I am more than happy to talk further either through continued correspondence, phone calls (I can be reached at ###-###-####), or even a trip down to the state house to talk in person. Thank you for your time in reading this and I hope you make the best decision for our state.

Sincerely,
Ryan J. Haupt
Masters Candidate
Vanderbilt University

It has me reading more than I have in years – but the real change was the realization that it brought me to. That realization was that I am living a life full of distractions. Email, Facebook, Twitter, various blogs, sports results, and the news cycle in general, these things all compete for my attention – and these are just the non-work related items. But, we all know this already. I knew it intellectually, but I didn’t know it intuitively.

Why did the Kindle make this clear to me? Because I bought it for the same reason that anybody buys one. It should simplify your life, and it really did. No more heavy books to tote around or to take up more room on shelves. Really the same reason someone buys a laptop or a smartphone – to combine lots of disparate things into one. But the problem with those devices is that even though they make your work easier (they help you accomplish tasks), they also invite you to avoid those tasks or just forget about them all together as you check your Facebook feed one more time. So really, if you aren’t careful, these things make your life more complicated not simpler. The Kindle doesn’t do that. Theoretically you can check email or got to a website using the Kindle. But, in reality it is a laborious task to undertake. I don’t think I’ve ever done either using my Kindle. Why is this a good thing? Well, it would take me forever to read a book on an iPad because I’d be just as likely to check Netflix to see if there was a movie I’d rather be watching.

The beauty of the kindle is that it does what it is supposed to do – replaces bookshelves worth of books and… that’s it. That’s enough, it doesn’t need to do anything else. It’s actually better that it doesn’t. That concept became vaguely clear to me in the first few weeks I used it, and it has only crystallized further in the subsequent months. The Kindle is actually better because it does less. It does one thing and it does it well. Maybe lots of things in my life would be better if they did one thing at a time. Maybe I’d be better if I only did one at a time. The Kindle does a rare thing, it combines what used to occupy a lot of space into very little while still allowing you to focus on what’s important. When you turn on a Kindle you don’t send a tweet, you just read.

(Find the video after the jump)

I think this just goes to show that me and the other Paleopals really love science to the point of absurdity, and can be found out in the world basically living as we do on the podcast (i.e. beer in hand, science in mouth). The audio quality is a bit rough but I sincerely appreciate Rick turning his lens on me and my antics long enough to pontificate on some paleontology. I hope you enjoy watching as much as I did filming.

And one last lingering question I cannot help but ask: how would you feel about more video content in the future? No promises at this point, but letting us know can only help to encourage!

I asked a fellow grad student, Tim, who knows about these things, just how an emerald could grow to this size.  His answer reads like a recipe, but probably not one you could make yourself.

First, you need a lot of water, heat, and beryllium. Beryllium (Be) is one of the main constituents of an emerald. It’s a relatively rare in continental crust, but can be found concentrated in mafic and ultra-mafic rocks, such as those uplifted from the mantle or oceanic crust. The Be is eventually leached out of the rock by a hot fluid of the right chemical composition, so what kind of fluid does it take?

It's what dwarves play football with.

Here’s where’s the science gets tricky. The water needs to be able to dissolve sufficient amounts of Be, as well as aluminium (Al) and silicon (Si). The full chemical formula for beryl is (Be₃Al₂(SiO₃)₆). The green color comes from trace amounts of chromium (Cr) or vanadium (V). According to Tim, the water is usually from a hydrothermal source already containing carbon dioxide (CO2), chlorine (Cl), sodium (Na), calcium (Ca), and magnesium (Mg), so it’s essentially a carbonic acid brine, which are associated with hydrothermal alteration of oceanic crust. These compounds and elements all aid in Be solubility and mobility.

The fluid and heat come from a nearby granitic or magmatic intrusion. Temperatures below around 500 degrees C result crystallize magmatic components, leaving behind the hydrothermal fluid saturated in incompatible elements. The fluid pulls Be out of the oceanic crust, leading to the precipitation of an emerald following subsequent changes in the chemical or physical conditions of the fluid.

That’s how any basic emerald forms, for an emerald this size you’d need a large fluid volume and a particularly high concentration of Be. Very cool! We really don’t talk about hard rock geology on the show enough…

The emerald’s Brazilian name, Teodora, translates to “Gift of God.” I’ll thank geology. And Tim. Thanks, Tim!

For anyone that can read:

The Kindle, I eyed it suspiciously for years.  For the record I love books.  I like reading just fine, but I love books. But maybe the zen existence I’m living in California eventually caught up to me and I’m starting to appreciate the minimalist approach to all kinds of things, or maybe I just lugged my ever growing collection of dead trees around the country to one too many new apartments.  Whatever the reason, I’ve fallen in love the Kindle. That screen is so nice, after staring at an LCD screen all day, you come home turn on the Kindle (whose battery lasts forever) and read what looks to be ink on paper. I almost wrote a whole blog post on my Kindle, but was too busy reading on it to be bothered. Anyway, they are cheap and the special offers version often offers $1 books.

For kids that love natural history museums or, just as well, adults that love natural history museums:

Wonderstruck by Brian Selznick

The American Natural History Museum in New York takes center stage in the plot of this mystery.  So, this is a doubly appropriate gift if the person you have in mind lives near enough to NYC to make a visit to the museum a reality once the novel has been digested and is back on the shelf.

For the Potter Fan:

Most of the HP stuff is wildly overpriced. I won’t tell you how much my wife paid for a golden snitch Christmas tree ornament.  This however, looks just as good in my mind, and is much, much cheaper.  A golden snitch antenna ball topper.  Put it on your car, leave it lying around your study, or add it to your quaffles.

You know what would be even better, something that a Potter fan would enjoy that wasn’t officially licensed by JKR. Here is the perfect solution. A real deal feather quill set.  The same one JK uses for all I know.  Also, good for the Deranged Millionaire on your list.  Speaking of which…

For the Deranged Millionaire:

A wall tentacle. Really I guess it should be from your favorite Deranged Millionaire, because that’s the only person that can afford it. And, furthermore, it’s actually not even a solstice gift, because if you ordered it today it wouldn’t be done in time for the Solstice, or even Christmas.  It takes eight weeks because they are all custom made.  Smaller varieties are available for less (medium  small I’m not sure how long they take to prepare). But this kicks off my list of things…

…For Cepholopod Lovers:

Cephalopods are in, I can feel it. It used to be zombies, and I guess zombies are still in, for reasons I don’t quite understand. They just refuse to die (badum ching).  It might be the rise in all things cthulhu that is inspiring our inner cephalopod, but I think it’s probably Dr. Zoigberg. In any case, I present to you a collection of cephalopodian weirdness at many different price points from across the interwebs gathered here for your solstice shopping convenience!

We all like to think about cephalopods, but where more than in the shower? Why not increase those soapy sentiments with a nice shower curtain or a squid caddy?

Afterwards, you can continue your morning octopus meditation with a cup of tea and tentacles.

Finally, I wrap up with something we can all agree to enjoy, having tentacles for fingers.

For those Sci-Fi fans…

Who doesn’t have a friend that will reenact the alien chestbusting scene at the drop of a hat?  Now, with this key prop, you might actually figure our what they are doing.

I probably recommended this taun-taun sleeping bag last year, but here it is again.  I think it pretty much speaks for itself. If you think they stink on the outside… check out the blue intestine patterned fabric on the inside.

For any other kid on your list:

Their parents will probably appreciate this monster hoodie because it is quasi-useful, the kids will love it because, well, because it’s a frikkin monster.

First thing you should do is light up their room and remind them of the warm evenings of summer with an electronic firefly in a jar. Not only is this a cool gift, there’s no guilt when you wake up in the morning to find all the little lightning bugs dead. Seriously, what was that all about? Does anybody know why those bugs are so eager to give up on life? But I digress…

As much as we may want to remind our friend that it will be warm again sometime in the future, we shouldn’t deny the reality that it is actually cold out. So I recommend getting your friend a jacket from SeV, makers of clothing with many pockets. There’s something quintessentially geeky about loving pockets, but I know I do and hopefully you do too. I have a pair of pants with 9 pockets. That’s right, 9. And this jacket puts those pants to shame. Fortunately pants and jackets can be worn at the same time for some serious constructive interference. I’m not sure I could even fill that many pockets and still be able to move.

Another way to keep warm is with a hot beverage. We may not usually have them on the show, but we Paleopals are caffeine fiends. I think we each have our own way to consume the glorious chemical energy. I prefer straight black coffee, and while I have yet to try it from a civet’s butt, I’d certainly try it if someone else paid for it. Then again there’s always the monkey-picked tea alternative (disclaimer: may have actually been picked by apes). But perhaps we should just keep things simple with a glass for our most on-air consumed drink Beryllium and Erbium. Think about it.

I think the only other thing your friend needs to get through winter is some reading material (or listening material in the form of an iPod pre-loaded with our show). Now by way of shameless plugging, I think some of the books by people we’ve had on the show are the perfect choice. I won’t give you an exhaustive list (we have a guest list for that) but I’ll give what I think the best choices are from a few different categories:

Novel – Midwinter by Matt Sturges (Episode 28), fantasy for the snow

Nonfiction – The Science of Kissing by Sheril Kirshenbaum (Episode 73), snuggle up and keep warm

Comic – Starman Ominbus Vol. 1  written by James Robinson (Episode 8), there’s even a touching Xmas issue!

And I’d be remiss if I didn’t mention our own store, full of shirts, mugs, glasses, and other Science… sort of accessories! If you don’t have friends who listen to the show put the gear you want on your own list. You deserve it.

I think with all this you’ll be well prepared to survive the Solstice and make the geek in your life happy. It’s the shortest day of the year, so it’ll literally all be over soon.

Turns out that Physics is full of SUPER SEXY IDEAS which are way too technical for science journalists to talk about. No, the best way to taste this fruit is to go to the tree. I (ben) have assembled a team: my titanium physicists. A group of  the rarest sort. technical experts, and also lucid and fun.

But you can’t just throw a group of experts together in a room. they start talking technical and it’s impossible to follow. So to keep everything under control, we bring on a special guest each week! Awesome people who are good at interrupting nerds.

the result is a half-hour long show, released fortnightly. it’s super fun and i encourage you to listen. we’re up on itunes!

Promo for Bodies: The Exhibition

While Ryan was enjoying New York Comic Con, I decided to take the opportunity to visit some of the Big Apple’s awesome museums. I left the choice of museum up to my good friend Rick, a New York native and fellow nerd, and he ended up taking me to the South Street Seaport — think Fisherman’s Wharf, NYC-style — for a double exhibit feature, Bodies: The Exhibition [BtE] and Dialog in the Dark (to be reviewed soon). Some of you might already know about BtE, since it’s been around since 2005. Multiple variations on the theme have been around for nearly 20 years, so you may have seen Bodies: The Exhibition, or Our Body: The Universe Within, or perhaps you saw Body Worlds back when it came out in 1995. These exhibitions are all independently owned and run, but you’d be forgiven for confusing them because they’re eerily similar. Essentially, you wander through room after room of plastinated human bodies, learning about the various systems and structures under our skin, seeing comparisons of healthy versus diseased organs, and wondering how the displays were made and who on earth these people once were.

I had seen Our Bodies: The Universe Within with my biology class in high school, and as a result had a severe case of deja vu while exploring BtE. The bodies were posed in similar fashions, highlighting the same systems. The bodies also all happened to be Asian, which was rather odd and brings up a whole other issue of provenance. “Provenance”, from the French “provenir”, means “to come from”. In the museum world, every item in your collection, be it a piece of artwork, a natural history specimen, or a body, needs to have some chronological record of ownership telling you who created and owned the work, or who collected a specimen when and where. Provenance matters for academic record-keeping purposes, and from a legal standpoint. For example, in the case of Nazi-looted art, if a museum acquires a work that had been stolen from its owners, the owners and their descendants still have a legal claim.

There’s some controversy over these two “body” exhibitions because of the provenance issue, with speculation that the bodies on display belonged to executed Chinese political prisoners. I don’t know if the truth is quite so gruesome, but it’s certainly unsettling to know exactly what someone’s stomach and intestines look like but still have no idea who this person was and how they ended up here. We do know that the bodies were received from the Chinese Bureau of Police, but there’s no further information as to whether they were sold on the black market or taken from prisons. Premier Exhibitions Incorporated, the company that runs BtE, has stated that it saw documentation for each of the cadavers, but couldn’t provide proof of the circumstances that led to the death of the individuals. The Body Worlds exhibition says that it gets its whole-body plastinates from donors who gave informed consent as participants in a special body donation program, but that hasn’t stopped some groups from feeling squeamish about the whole idea of displaying cadavers.

So what on earth does it mean to be plastinated? Plastination is a way of preventing decomposition that lasts longer than traditional embalming. Essentially, you replace the water and fat in tissue with plastics called curable polymers, which include silicon, epoxy, and polyester copolymer. As a result, your specimen doesn’t smell, can be manipulated, and retains a lot of its original features like shape and color. There are three centers for the Institute of Plastination, one in Germany, one in Kyrgystan, and one in China. Here are the main steps of the plastination process patented by Gunther von Hagens back in the ‘70s:

• Step 1: embalm the body (or organ) in a formaldehyde solution. You don’t want the specimen to rot while you’re preparing it.
• Step 2: do whatever dissection you need to do. Say you’re showcasing the reproductive system, well, you’d want to remove anything that’s in the way or obscures your view.
• Step 3: place your specimen in an acetone bath and freeze it. The acetone will replace all the water in the cells.
• Step 4: place your specimen in a liquid polymer bath (ex: epoxy resin), and create a vacuum. This will cause the acetone to boil out of the cells, drawing in the liquid polymer. Now your cells are filled with liquid plastic. Hooray!
• Step 5: cure the plastic with UV light or heat or gas to harden it into whatever shape you want.

Now you have yourself a plastinated specimen! Impress your friends and horrify your elderly relatives!

Ok, back to the exhibition. You start off in a room with giant wall-labels about major figures in the history of medicine, explaining when we discovered certain features of the human body. The most amazing thing about this section is how little we knew for how long. It’s not till the 1800s that the pace of discovery really starts accelerating, and that we start practicing anything like modern medicine. Frankly it’s a miracle we’ve survived this long.

You start with the skeletal system, and more layers are added (or rather, are emphasized) as you move from room to room. By the end, you’ll have seen an isolated circulatory system, every single muscle in the human body, the nervous system, the digestive system, the respiratory system (including non-smoking PSAs), the urinary system and the reproductive systems. There’s also a separate gallery containing fetuses from every point of a pregnancy, that I found fascinating if only because you can see the development of the skeletal system. In each room there are cases full of individual organs and cross-sectioned views, and a full-sized plastinated body posed in a manner that highlights the theme of that room (except for the reproductive system room). For example, in a room about prosthetics, you have a discus-thrower whose muscles have been cut away at curious points to reveal what a hip implant, a knee-restructuring, a rod-insert and back brace look like. In the respiratory system room, you’re encouraged to throw away your packets of cigarettes. In room after room, you see glossy blobs of cancer covered organs, which will renew your will to train for cancer runs and walkathons.

The whole production quality of the exhibition is excellent, with human body factoids and beautiful designs on the walls, excellent lighting, plenty of space, and the occasional video and interactive. True, the labels were often small and hard to read, and sometimes the body poses were a bit much (the bisected man high-fiving himself, the woman holding her torso muscles open like a cupboard door to reveal her organs), but the end result was a fascinating peek at what we don’t normally get to see.

I think that’s the crux of the tension surrounding this exhibition — we never get to see what’s under our skin, and we grow up thinking it’s gross or wrong, but we still want to know. This is why we have horror movies, for the fascination of getting to see the “unheimlich” aka the “uncanny”, things that we used to be intimately familiar with and are part of us but that are now taboo. It’s also why my friend at UC Berkeley’s Museum of Vertebrate Zoology thinks we stop at car-wrecks. She doesn’t rubberneck because she knows exactly what mammal organs look like, but unless you’re a surgeon, a pathologist, or you work in a museum’s specimen prep lab like she does, accident scenes are your only chance to see what’s inside. Should we feel weird about an exhibition like BtE? Or should it get the same treatment as any other science/natural history topic?

It really is too bad that these types of exhibitions are bogged down in provenance issues, since at the end of the experience, you gain a whole new sense of respect for your body, and for what it does automatically every day. By proceeding in such a controversial way, the creators of the exhibitions do a disservice to the scientific content. If you knew that the cadavers were willingly donated and the whole process was documented and above-board, you could focus on learning more about your body. Knowing more about your body helps you make smarter decisions about your lifestyle and health care, and be concerned about the health of others. If you know how much left is left to learn, you may become more supportive of scientific endeavors. A lot of the messaging in this exhibition was about how to stay healthy, but there’s so much more we could talk about. Imagine displays on comparative anatomy, like if Your Inner Fish was adapted from book to exhibition. Or displays on the history of medicine, or even what cutting edge science is discovering. There’s a whole world (or universe) within, why not explore it?

Juliana hopes this post didn’t make you too squeamish. Her tweets are usually less grotesque, unless they’re about Ryan, cause he’s icky.

Another in our series of Ben’s ramblings Patented Wisdom BOLTS that didn’t make it to air! This week Chad asked us about our thoughts on math education, and Ben had things to say. We were running long I Didn’t want the reader’s ears to explode with wisdom so I didn’t read it, but I’ve posted Chad’s question here followed by Ben’s response. It’s interesting stuff from the newly minted PhD and teacher  the prophet of thunder, so hopefully you’ll enjoy reading it as much as I did.

This is primarily directed at Ben and Charlie – the math and physics guys, but I am sure everyone will have an opinion… The subject may be a little out of context, but ,there was recently an op-ed piece in the NY Times about changing the way we approach the way math is taught – proposing that we lose the geometry, trig, pre-calc, calculus progression and swap in more contextual subjects such as finance, data and engineering to convey the math concepts.

How To Fix Our Math Education

Given that complex math is such an integral (pardon the pun) part of science – especially physics, do we risk losing some good minds by “dumbing down” our math instruction?

No worries if this doesn’t fit the discussion.

 

Lets talk about this in terms of carts and horses.

so right now, the math education system goes “hey, lets teach the horses to get all harnessed up and push carts from behind. There’s all sorts of carts they can push. physics carts. economics carts. logical reasoning carts. biology and business. plus, it’s a good way to weed out the really strong horses that are good at pushing, and the horses trained this way get really strong”.

on the other hand, the writer of the article [who proposed replacing abstract subjects, with subject specific problem solving] suggests that in doing so, we are putting the cart in front of the horse. His argument, to paraphrase, is that “most horses walk must better when they can see where they are going. and that more horses will get stronger and better at walking in the process.”

I can kind of see both sides of this issue. As a physicist who has to take math classes on occasion (*ughhh*) I can say that it’s MUCH EASIER to learn math when you know where it’s going. And as a math educator, i can honestly say that there is a canonical way of teaching math which desperately needs re-evaluation. In so far as university mathematics goes, I think that the education system reinforces its teaching practices, selecting the students who best learn math in this specific way, and who go on to teach the math in the same way.

 

On the other hand, as I said before regarding horses: the current education system (especially at the precalculus level) selects out the students who are good at this type of problem solving, and furthermore this abstract education makes people stronger at math. Do you think that more people would enroll in engineering if we taught math differently in high school? I’d wager exactly the same number of people would enroll in engineering. What’s more, from experience, learning the theory and practicing in the abstract often makes for stronger and more versatile thinkers. I can’t imagine learning calculus only from a physics course. or algebra only from a… what? a physics course?

It’s clear that innumeracy is one of the “problems” which we want our golden society of the future to have conquered. So yes, i’d like our math education to be more inclusive. Is it a question of quality or curriculum? maybe it’s both. but we should make note of one important thing before we take an axe to the pythagorean theorem. Math is a useful and wonderful tool because it is (by it’s very nature) abstract. it’s the most abstract of all the subjects. In this light, wouldn’t taking the abstraction out of the math class be like taking the lyricism out of poetry class?

get that horse back behind the cart where it belongs.
stupid horses.

horses are stupid
