Ravenous curiosity
It’s not that religion is inherently incurious. Religion and science are both planted in the cortical freakishness that demands answers. It’s just that religion wants the answers it wants, while science wants the answers that are in the answer key. Also known as “the actual answers."

Kid Science : Frozen Ocean
A light bulb went off in Emma's head - it was an amazing thing to witness. "I know what we can do! Let's put a container of water without salt and another container of water with salt outside and see if they freeze!" I can't explain how proud I was at that moment. Notice that Emma did not just want to put a container of salt water outside and see what would happen. She wanted to put both salt water and fresh water out - she had just designed a simple controlled experiment. I was smiling all the way to work that day.
The weather warmed up for a bit after that conversation, so we had to wait until yesterday to carry out Emma's experiment. After dinner, we pulled out a couple of bowls, a measuring cup, a kitchen scale, and some table salt.
I was trying to keep everything as accurate as I could so we added 500mL of tap water to each bowl and added approximately 17.5g of salt to one of them (this gives a salinity of 3.5% or 35 ppt, the average salinity of ocean surface waters, and only slightly higher than the salinity we would expect for the ocean off of New England). I asked the kids what else we needed to do and Emma realized that we needed some way to identify each bowl. She had some trouble coming up with a good system. Jack, of course, figured it out - "Emma, we just need to write 'salt' and 'no salt' on a piece of paper and tape it to the bowls."

The kids put the bowls outside on the back deck and went off to bed. I watched the temperature outside drop through the evening: 30oF, 28oF, 25oF, 23oF, 20oF. Uh oh. I hadn't anticipated such a cold night. Salt water doesn't freeze at 32oF, but it will freeze - especially sitting there in a little bowl without currents or waves - in fact, water with a salinity of 35ppt will freeze at 28.8oF. The reason the ocean as a whole doesn't freeze even when it's sub-28.8oF outside is that it has such a huge thermal mass that the water itself doesn't often get to 28.8oF. You'll see some freezing in shallow areas with little wave activity, like along the edges of tidal marshes. I was starting to fear that our little controlled scientific experiment was going to backfire and we would wake up to two frozen bowls of water and the kids would logically conclude that the salt did nothing to prevent freezing. D'oh!
When I went to bed sometime around midnight, the temperature outside was 18.8oF. Should I bring the bowl of salt water inside and then wake up before the kids, run downstairs, and put it back outside? No. That's just too deceitful and is completely counter to the lesson I was trying to teach about scientific thinking. I'll just hope for the best - perhaps the salt water wouldn't freeze as much as the fresh water. I went to bed hoping for a watery slush.
When we brought the bowls in this morning, sure enough the salt water had froze. But thankfully, like I had hoped, it was different from the fresh water. The fresh water was frozen solid, smooth like a hockey rink. The salt water was slushy, not firm at all. The kids marvelled at the difference. They banged their knuckles on the hard fresh water ice and stuck their fingers through the salt water slush. "Wow, the salt water isn't really frozen!". They played with, touched, and tasted the ices for a few minutes then headed off to get dressed for the day. Whew. To paraphrase a cogent comic - Science. It works.

Planting a Meadow
Part of our backyard is a swath of land with a utilities easement on it - we own the land, but the gas company has access rights and nothing can be built there. Previous owners planted grass back there and, so I've heard, kept it mowed like a lawn. I haven't continued this practice since 1) I have no desire to spend the time and energy to mow more lawn, and 2) I like my yard to provide as many natural habitats as possible (and a mowed lawn ain't much of a natural habitat). I would love to naturalize this entire back lawn, but it is a pretty big space and would require more time/effort/money to remove the existing grass than I am willing/able to give. So this summer I decided to start small.
I chose a small (~400 ft2) area to work with, figuring I can expand things in subsequent years if this preliminary work goes well. I started this project back in June, when, after mowing the grass short, I covered the area with some nylon tarps. I kept these tarps in place from June until this weekend. By keeping the area covered during the entire growing season, keeping the sun out and the temperature up, I was hoping to kill both the existing grass and a decent percentage of the grass/weed seeds lying dormant in the soil.

I pulled the tarps up this weekend and, sure enough, all vegetation was dead:

After some raking and hoeing up of dead grass tussocks, the area was ready to be sown:

By sowing seeds now, in November, in New England, I am accomplishing a couple of things. First, the wildflower and grass seeds I sow now will already be in place in the spring, ready to germinate as soon as conditions are right - this should give them a leg up (or at least an even footing) with any weed seeds out there now and I won't have to worry about working around my schedule or the unpredictable spring weather to plant. Second, some native wildflower seeds require a period of cold dormancy before they will germinate - I could have put the seeds in the fridge for the next few months, but why bother when winter can do a better job for me?
I wanted to plant a meadow, not just a wildflower garden, so I ordered both wildflower and grass seeds. I also wanted to use as many native plants as I could. After some online research, I ended up with a native wildflower seed mix from American Meadows and a short prairie grass mix from Prairie Frontiers. I augmented these with some additional native wildflower seeds. I bought enough seed for approximately 1,000 ft2, figuring I'd use half of it this year and the other half for next year's expansion.

Following a technique I found online, I split the seed I was going to use this year into two parts and mixed each part with approximately 10 parts of clean sand, which makes sowing the light, small wildflower seeds much easier. After thoroughly mixing the seed and sand, I sowed 1 part over the entire plot moving east-west and then sowed the 2nd part going north-south, thereby minimizing bare/sparse areas. The last thing to do, which is oh so important (so I've read), was to compact the seeds into the soil to ensure good seed-soil contact. Since I don't own a grass roller, I spent a half hour or so stomping around the sown plot, making sure my footprints covered every square inch of the ground.

Now I just sit back, enjoy the rest of the fall and winter, hope the birds don't eat too many of the newly sown seeds, and keep my fingers crossed for successful germination. I'll keep everyone posted.

Symposium on Marine Renewable Energy
This month, developing that framework will be the focal point when domestic and international scientists, business leaders and policymakers – including U.S. Senators Jack Reed and Sheldon Whitehouse, Rhode Island Gov. Donald Carcieri and a host of others – converge at Roger Williams University on Oct. 23-24 to find real-world solutions for tackling the legal, economic and policy challenges of the nascent marine renewable energy industry.
At the law school’s 7th Marine Law Symposium, this cross-disciplinary gathering of experts will grapple with the “how” of developing offshore energy resources, addressing concrete ways to support the burgeoning marine renewable energy business market, while attempting to reconcile a tangle of local, state, federal and public interest needs related to the protection, conservation and management of valuable marine resources.
Although registration for the event is closed, it is going to be streamed live at mms://streamer.rwu.edu/marinelaw and apparently there is going to be some live blogging of the event.
Perhaps I'm not in the loop as much as I would like to be, but I'm amazed that I didn't hear about this event until today. In fact, the only reason I heard of it at all is because an email went out to everyone concerning the parking ban in effect for the event! In any case, this is an important topic, especially for coastal areas, so hopefully something good comes of the symposium.

It's all woo to me
The transformation of energy into animate matter seems to occur generally within a container of some sort, a membrane, a pouch, a seed, or a shell. An egg is arguably the most pristine archetypal form among all receptacles within which life is engendered. Created at the inception of life, this completely sealed form vibrates with a latency manifest in its aura of impeccable silence. Even when an egg is broken and deserted by the life it once hosted, its inner depths seem to continue to ring with the memory of the transformative miracle, which took place within.
I think I'll skip this one.

Math problem help
Given an infinitely (sufficiently) large population of marbles of which 10% are green and 90% are blue, what is the probability of picking 10 marbles of which exactly 3 are green?
I know the chance of picking one green marble is 0.1, and I know that the chance of picking 3 green marbles in a row is 0.001 (0.1 x 0.1 x 0.1). But I'm confused when it comes to figuring in that order is unimportant and that a finite number of marbles is being picked - clearly the chance of picking exactly 3 green marbles in 10 tries is different from picking exactly 3 green marbles in 100 tries. Any help? In the end I'd like to generalize the process - given a population of which X% are a given kind, what is the chance of subsampling exactly Y individuals in Z tries.
Thanks in advance...

"...set an open course for the virgin sea"
![]() |
2008 - 2009 ANNOUNCEMENTSEA is now accepting applications for the 2008-2009 academic year. Sea Education Association now offers three unique opportunities for undergraduates to spend a semester studying the oceans in the world-renown oceanographic community of Woods Hole, MA and aboard one of our modern sailing research vessels during an oceanic passage in the Atlantic or Pacific Ocean. SEA Semester: Ocean Exploration - This long-standing, innovative program offers students of all majors a multidisciplinary approach to studying the world's oceans from scientific, maritime cultural, and modern seafaring perspectives. Celestial navigation, meteorology, seamanship, oceanographic sampling techniques and research, and maritime history, literature and policy comprise the core curriculum. SEA Semester: Documenting Change in the Caribbean - Humanities, Environmental Studies, Geography and Social Sciences students are prepared for an extraordinary project-based academic experience. Few regions have seen such enormous changes in the last five centuries as the islands in the Caribbean Sea. Today, there is a dynamic mix of cultures and biota in the islands that bears little resemblance to the world encountered by Christopher Columbus. Students explore how we can document these changes using maps and charts, historical documents, commercial records, harbor pilots, species surveys, and the literature of Caribbean people from both the Colonial and post-Colonial periods. SEA Semester: Oceans & Climate - For advanced science students. This program focuses on the importance of the equatorial Pacific to the global carbon cycle, and culminates in a trans-equatorial research cruise from either Mexico to Tahiti or Tahiti to Hawaii. SEA faculty and visiting researchers from across the country engage students in oceanography, ocean policy and the operation a sailing research vessel. www.sea.edu |

Hulkamania?
So, the kids and I take the metro down to the Mall and sure enough we're bombarded by pamphleteers as we leave the metro stop. I managed to fend off the hoard without taking a single "You're going to burn in hell" flyer/newspaper/brochure. As we move away from the crowd I see a monstrosity of a stage set up by the Capitol - it looked like a Def Leppard concert (no offense to Def Leppard) - and we hear someone on stage yelling and carrying on about something. Honestly, I have no idea what the guy was saying, but the tone and rhythm sent chills down my spine - it's hard to explain, but it was some combination of anger, insanity, and overacting (I hate to suggest this, but check out the video on the right side of the Call's website I linked to above to hear what I mean). I suppose, unsurprisingly, evangelical is the best word to describe it. The guy could have been reading directly from Isaac Newton's Principia and it would have sounded just as scary-insane.
Actually, now that I think about it, the whole thing reminded me of something like this
So, what did the kids and I do? Walked straight across the Mall to the Museum of Natural History, of course, and took part in, among many other things, the Mammal Family Reunion.

Our second (and last) "Sugar Baby" watermelon from the garden. The first was picked too early. This one was excellent even though it could have ripened another couple of days I think - except for the fact that some critter (squirrel? chipmunk?) was starting to nibble on the rind. Better to eat it a bit early than risk losing it completely!

That's a lot of gorillas!
At first I thought the 125,000 number must be a mistake - I would have thought finding 30 gorillas was a big deal. But then I read that these gorillas were found in the swamps of equatorial Africa in a remote part of the Congo, so I can understand why they hadn't been found before. Just thinking about their location gives me malarial chills...

Friday Dial Stopper: Poster Printing Edition
1) I met the IT guy at the room so he could let me in and log me onto the computer. He shows up and says "I hope the door isn't locked, that's the one key I don't have". Wah!? Now remember, this is the same guy that let me in yesterday (he had a key then), the same guy I talked to on the phone 15 minutes ago and who told me to meet him here so he could unlock the door for me, and the same guy who called security yesterday to come and lock up the room (oh, just to cover all bases, this is the same room as it was yesterday). Of course the friggin' room is locked. As my grandmother says (surprisingly) "Jesus, Mary and Joseph!" I shouldn't be surprised though since this is also the same guy who was "hoping" no one needed the regular printer this summer.
2) The IT guy finds someone with the key. Once inside I realize that the roll of paper I left on the printer is no longer there - it's been swapped out with smaller, cheaper stuff. My roll is nowhere in the room. WTF!! Luckily, the guy with the key had some ideas where it might be and after searching through about 5 different rooms we found it in a storage closet on the other side of the building. So much for being out of here in a couple of hours.
So, today's dial stopper is fitting. Just change the words in the chorus from 'I' to 'IT' (as in Information Technology) and it's perfect:

While I'm blogging about sports...
...it would so much fun to see Gibbon Jockey's reaction...
Manny Be Gone
Thankfully, Manny Ramirez is leaving Boston. I wish it hadn't come to this, but he has become a major pain in the ass over the past few weeks - getting into fights with teammates, knocking down elderly club assistants, refusing to play, making up injuries, saying that Boston doesn't deserve a player like him, etc, etc. All because he really didn't want the Sox to pick up a $20 million option for next year (don't you hate it when someone wants to pay you $20 million a year?). Manny being Manny just went too far.
I always kinda liked the guy - a big goofball who could hit the crap out of a baseball - but with the way he's been acting lately (like one of my kids when they were 2 and were told they couldn't have ice cream) I'm happy to see him go. Looks like the Sox are getting a decent player in Jason Bay in return, but we'll see (and really, at this point, I don't really care). Everyone on the team has to feel better right now - especially Tito (Terry Francona, the team manager).
The only downside to this whole thing is that my 4-year old son, Jack, lost it when he heard the news (we were listening to the radio waiting for Emma to get home from camp). Tears, sobbing, pure uncontrollable (and inconsolable) emotion. I didn't know he was so attached to Manny. I don't even want to think about how he is going to react when the same fate befalls his favorite player, Jason Varitek. He's going to be absolutely crushed. But maybe Manny's departure will help soften the blow - Jack won't be so blindsided by the fact that this happens.
Anyways, I am 100% ready for the Manny-less era to begin. Good luck, LA! Repeat after me, it's just Manny being Manny...
Research poster frustration (take 3)
Next Monday there is a conference co-hosted by RI-INBRE and RI-EPSCoR, two federally-funded state programs that, among many other things, provide support to undergraduates to do research. This conference consists of poster presentations for all the Summer Undergraduate Research Fellows (SURFs) from both programs throughout the state. As such, I am printing 10 posters for the SURFs here at RWU.
Not too bad, right? Each takes about 15 minutes or so to print, so I block off a few hours and give myself another day just in case anything goes awry. Am I prescient or what...
1) Poster files were due in to me by 10 a.m. this morning. How many did I have by 10 a.m.? Exactly 1. This was expected of course so not too big a deal.
2) The one laptop that is reserved for use with the large-format poster printer is kept in the Dean's office (this way we can maintain strict control over who uses the plotter - we don't want just anyone trying to use it and end up f-ing it up). However, the Dean is not here today. Neither is his secretary. The other secretary in the building doesn't have a key to his office. Luckily, security does and happily opens the door for me (wonder if the Dean knows about this).
3) The printer sits in a little room off the back of a computer lab. I have a key that opens up both the computer lab and the little room in the back. So, I unlock the computer lab and attempt to unlock the room in the back. My key doesn't fit. I try again and again and again, thinking it's just a bit sticky. Nope. No good. My key clearly does not go with this lock. Another call to security...
4) Security shows up. Long story short...their keys don't work either. WTF!?!? Security calls the locksmith. Turns out that the lock has been changed and the only folks with a key are over in IT. Apparently they're using the room for the storage of new PCs until they get a chance to swap out a bunch of old ones. Security bids me adieu and wishes me good luck. Great.
5) I call IT. Finally I get connected to someone with the key. I tell him what I need and he says...nothing. Just silence on the other side. Then I get a "Hmmmm. Huh. Ahhhhh. Can I call you back?" Sure. Why should I have expected a simple, "OK, I'll be right there"?
6) He calls back. I can't get access to the printer. I repeat, I cannot get access to the printer. Turns out the printer has been taken offline, moved to the back of the room and buried behind boxes of new PCs. It is literally inaccessible. Apparently, IT had been (direct quote here) "hoping that no one would need the printer this summer". Wah? Hoping? Other than IT (and the locksmith I guess) no-one knew this was happening. They didn't tell (or better, ask) anyone. They just were hoping it would be OK. Wow.
Everything is not lost however. The guy from IT has given me access to the computer lab in the School of Engineering. There's an older large format printer over here that I am using...once I changed the paper, figured out the proper settings, and fought with the paper loader because the roll I have is too thick so the rollers get jammed. But I'm printing now and, knock-on-wood, everything looks good.
And I remembered rubber bands this time!

Marine bio Camp - day 6 recap
- Saw five humpbacks up close, including two cow-calf pairs, as well as a couple of minke whales and a fin whale off in the distance
- One of the humpback whales we saw was Salt, the first humpback to be given a name some 30+ years ago, and her new calf, Sanchal .
- Great bubble net feeding beahvior
- Best of all, Sanchal gave us a show with a "spinning head breach" right in front of the bow of the boat. This was the first time I had ever seen a breach and was as amazing as I thought it would be!
It was an intense week - I feel like we did an entire semester of a Marine Bio lab/field course in one week. I think I'll go to bed now and sleep for about three days!

Marine bio Camp - day 5 recap
Morning Session
Trawling on the 54' fishing vessel, the Captain Bert - students got to see the deployment of a smallish otter trawl and learn some fish biology while examining the haul;
Our catch included fluke, flounder, lobstahs, sea robins, scup/porgies, and squid;
Observe fluke dissection - examine internal anatomy and stomach contents (two recently eaten scup);
Afternoon Session
Winkler titrations of light/dark bottles from yesterday;
determine and graph primary productivity (gross and net) and respiration rates for surface and deep water;
Evening Lecture
Marine Mammals, given by yours truly (why me? cause our resident marine mammologist is on sabbatical and I lost the coin flip; thank goodness for wikipedia!)

Marine bio Camp - day 4 recap
Morning session
Take RWU boats out for plankton sampling - one boat deploys a 150μm zooplankton net, the other deploys a 20μm phytoplankton net;
Using Van Dorn bottle, collect water samples and set-up primary productivity analysis (using the light/dark bottle technique);
In lab, use microscopes to examine the plankton samples - sketch and ID five phytoplankton and five zooplankton;
use spectrophotometers to measure chlorophyll concentration in samples filtered yesterday;
Afternoon session
Head to Fogland Beach for some fish seining along the shore and salt marsh;
Evening Lecture
Fish Biology
Highlight of the Day
Catching a 20-inch striped bass in the beach seine
Lowlights of the Day
1) Lion's mane stings
2) For tomorrow's Winkler titrations I wondered if I should use glass or plastic graduated cylinders. Are the high schoolers careful enough for the glass ones? I don't know...they're pretty fragile...and tippy (the cylinders, not the kids!)...oh what the hell, let them use the good stuff. Any bets on what I did while setting up? I decided to go with plastic.

Marine bio Camp - day 3 recap
Morning session
take RWU's two small boats (a 19' Lema Skiff and a 29' Master Marine) out on the Bay;
on one boat - take CTD and Secchi disk readings from three different stations; collect surface, mid-column, and "deep" water samples using a Van Dorn bottle (for chlorophyll analysis back in the lab);
on 2nd boat - deploy Van Veen Grab and small otter trawl, identify and discuss critters found
Afternoon session
discuss productivity, photosynthesis, and ways of measuring both;
process water samples collected in morning - for each sample, filter 1L through 0.5μ membrane, place membrane filter in 10ml acetone to extract chlorophyll, let sit overnight (will quantify chlorophyll spectrophotometrically tomorrow);
discuss what characteristics make a good graph;
create depth profiles using CTD data from morning (salinity, temperature, and dissolved oxygen vs depth);
interpret depth profiles and relate to the geography of the Bay;
Evening Lecture
Phytoplankton, primary productivity, and marine invertebrates (characteristics of major phyla) - presented by our two senior undergraduate camp assistants
Issue of the Day
Lost a kid. OK, not really, but one kid did decide that he hated the camp so much he didn't want to stay. So, his dad came by this evening, picked him and his stuff up, and took him home. Oh well. Maybe he was expecting dolphins and sharks or something.

Marine bio Camp - day 2 recap
kayak in Ninigret Pond;
explore the salt marsh, tidal flats, eel grass beds, sandy beach;
search for, find, and identify critters, discuss their ecology/natural history;
discuss sedimentation, local geology, glacial past, anaerobic decomposition, hydrogen sulfide production;
visit rocky intertidal zone at Beavertail State Park;
discuss important physical and biological factors at play here;
examine zonation;
search for, find, and identify critters;
compare and contrast with sandy beach environment;
Problems encountered:
Shuttle bus with students taking the long way around, getting stuck in morning rush-hour traffic;
kayak outfitter unable to unlock kayaks -> go out and rent bolt cutters -> cut lock;
kid from CA forgetting his parent-signed kayaking release form;
RWU shuttle failing to return to pick us up to take us to the rocky intertidal (they didn't see the second destination on the shuttle request form);
hung around kayak center parking lot for a couple of hours waiting for RWU security to "do their best to get someone out to pick us up";
had approximately 40 minutes at rocky intertidal;
one bloody shin and one smashed toe (neither mine);
At least it didn't rain on us. And I didn't lose anyone.

Kayaks, Winklers, and Otter Trawls....oh my!
- kayaking at Ninigret Pond - we'll explore this coastal lagoon (aka salt pond) and associated habitats (salt marsh, sand/mud flats, barrier beach, eel grass beds), keeping an eye out for as many critters as we can
- tidepooling at Beavertail State Park - a great, wave-swept, rocky intertidal area - perfect for observing zonation
- using a small, hand-deployable CTD to create water column profiles in Mt. Hope Bay (a part of Narragansett Bay)
- using Van Dorn bottles to collect water samples at various depths for chlorophyll analysis
- phyto- and zooplankton tows and then some microscope work to see what we caught
- investigation of primary productivity using light and dark bottles and Winkler titrations (if I can find the burets!)
- fish seining at a local beach - we should find plenty of silversides, mummichog, and sheepsheads, among other things
- deploying an otter trawl off the 54' fishing-cum-research vessel, the Captain Bert - I am really looking forward to this one as I have never done or seen this before - we should pull up a good variety of critters, hopefully with minimal harm/bycatch
- whale watching on Stellwagen Bank - a good way to end the week.
