LIDO: Your Live Whalesong Hookup

Hihi SF

Want to tune into some live whalesong?

Well, the new LIDO (Listening to the Deep Ocean Environment) site offers a live feed to 10 hydrophones in European waters, and one in Canada.  And as well as enabling us to listen as a whale whistles in Sicily, the network’s aim is to “record and archive long-term subsea noise so that researchers can study the effects of human activity on whales and dolphins” – the project hopes to use this technology to enable better understanding of the effects of noise polution on marine life:

Hydrophones can pick up sounds from baleen whales hundreds of kilometres away, so installations in different places could be used to triangulate an animal’s position and track its course. It should therefore be possible to determine if animals change course in response to bursts of noise, or alter their preferred routes because of new sources of noise like shipping routes or harbours.

Lest we forget: [Whales and] Dolphins are Awesome!

How Your Body Affects Your Thinking

Hi hi SuperForest

I just came across another interesting brain-related article on NewScientist.com – this time about how your body affects your thinking:

Now research suggests that our bodies and their relationship with the environment govern even our most abstract thoughts. This includes thinking up random numbers or deciding whether to recount positive or negative experiences.

To probe whether movements can drive thought, Daniel Casasanto of the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, turned to the metaphors that we use to speak of our moods. “We can hardly help mapping them onto a vertical, spatial schema, with the good end ‘up’ and the bad end ‘down’,” says Casasanto. “We talk of being high on life, or our mood taking an upswing, or feeling down in the dumps.”

The results also led to a deeper question: does physical movement have the power to change not just the speed at which people talk, but also what they choose to talk – or even think – about? Casasanto’s next experiment found that it does.

As the students were moving the marbles either up or down, they were asked neutral questions, such as “tell me what happened yesterday”. In this task, the subjects were more likely to talk of positive happenings when they were moving marbles upwards, and narrate negative stories when moving marbles downwards.

This raises a host of cool questions…

….can we make ourselves feel more positive by using our bodies in a “positive” way (could I make a ‘desk toy’ that required me to push marbles upward when I’m beginning to feel down? should you do jumping jacks before going into an interview? Is the bottom bunk really the better option after all, since you get ‘up’ to start your positive morning rather than ‘down’ from the top bunk?!;)

…. how much of this relies on language (moods being “up” or “down” ?) – do other languages have other norms?

…. and what of ROBOTS?! does this mean to be truly AI a robot would need to have a body? no brains in jars?

Thoughts, thoughts…

Alice’s Mathematical Wonderland?

Have you ever felt in Algebra class that you were sliding down a rabbit hole where things didn’t make sense any more? Maybe it’s because you were?!

alice_in_wonderland

Melanie Bayley, in New Scientist, argues that some of the most memorable scenes in  Lewis Carroll’s (or Charles Dodgson, Oxford mathematician’s) opus ‘Alice’s Adventures in Wonderland’ – from the cheshire cat, to the caterpillar, to the Mad Hatter’s tea party – were in fact a satirical analysis of the (then) newfangled ideas of algebra and abstract maths. The tea party and quaternions?

the parallels between Hamilton’s maths and the Hatter’s tea party – or perhaps it should read “t-party” – are uncanny. Alice is now at a table with three strange characters: the Hatter, the March Hare and the Dormouse. The character Time, who has fallen out with the Hatter, is absent, and out of pique he won’t let the Hatter move the clocks past six.  Reading this scene with Hamilton’s maths in mind, the members of the Hatter’s tea party represent three terms of a quaternion, in which the all-important fourth term, time, is missing. Without Time, we are told, the characters are stuck at the tea table, constantly moving round to find clean cups and saucers.

…Alice’s ensuing attempt to solve the riddle pokes fun at another aspect of quaternions: their multiplication is non-commutative, meaning that x × y is not the same as y × x. Alice’s answers are equally non-commutative. When the Hare tells her to “say what she means”, she replies that she does, “at least I mean what I say – that’s the same thing”. “Not the same thing a bit!” says the Hatter. “Why, you might just as well say that ‘I see what I eat’ is the same thing as ‘I eat what I see’!”

Hmmm… Or maybe the answer is that Maths is the Wonderland where fantastic things are possible?!

Laundry Day Greens: Let’s Hang Out! (or in)

clothesline-5-c

Evening SuperForest!

I came across this article in the New Scientist this evening and was surprised by how surprised I was: saving energy by hanging your clothes out rather than putting them in the dryer?  So simple!  So full of sunshine and fresh air!

I still hang my laundry (I fully admit, entirely through habit and not through a responsible thought process) but the New Scientist piece had some eye-opening statistics:

Some 80 per cent of US households own and operate a tumble dryer, with millions more of us going down the street to a laundromat. The average American household dries eight loads of washing a week; over 2 million households do 15 loads a week or more.

Needless to say, all this drying uses a lot of energy. According to figures from the Department of Energy, tumble dryers gobble up over 3 per cent of all household electricity, and that doesn’t include drying that gets done at laundromats, hospitals, restaurants, universities and prisons, which are home to 2 million Americans.

Yet clothes lines have become a rarity in the US, in part because draconian regulations make it impossible for many people to dry garments naturally. Around 60 million Americans live in homeowners’ associations such as condominiums, retirement communities and mobile home parks. Most of these ban or severely restrict the clothes line.

Clothes dried in a fresh breeze in the warm sun – sounds wonderful… But, not everyone has a garden, not everyone is allowed to hang laundry from lines outside, and sometimes the weather is just inclement. Hmmm…a barrier, yes! But one that can be hurdled! The humble clothes horse (do people still call it that? a clothes rack? indoor drying frame? now I’m just making things up) is totally practical. Ah! it is a horse!

clotheshorse

Fling the clothes on the horse, come back when they’re dry (or in winter, for heavy things like jeans, put them on the radiator – there’s some debate about the extra energy your heating would use to dry the clothes as well as heat your room, but if you have the heat on a timer anyway I can’t see how it makes a difference so long as your room’s still warm enough?). Sure, it takes a little time, but – depending on how slapdash your method – really not much, and it can be quite a meditative activity – plus it removes the shrinkage risk factor and it gives a little humidity: winter, central heating ravaged skin win!

Alexander Lee, the article’s author, runs Project Laundry List, a non-profit organisation dedicated to promoting line-drying and campaigning for the ‘right to dry’ outside. You can find out lots more about improving laundry efficiency and helpful laundry tips – and a great guide to practicing line drying on campus on the site.

I was again surprised by the heated comments to the article – in particular it hadn’t occurred to me as a feminist issue: can we, in good conscience, not use our dryers? by shunning labour-saving household appliances are we denying the advances of our gender? Well, for me, no (if I don’t do my laundry, before I go to work, nobody will) – but I can’t judge the position of a busy woman, looking after a family. Pegging the laundry may seem like stepping back into a traditional role.. but, male or female, I think it’s about having choices – we ALL have dirty laundry, but how we choose to deal with it is up to us:

It is not normally considered a proper subject for conversation, particularly among intellectuals, but if you start asking around, you will find that people take it more personally than you might imagine. Laundry, liturgy, and women’s work all serve to ground us in the world, and they need not grind us down.

Good Morning SuperForest,

For several months now, I’ve been getting emails from the most wonderful SuperForester. SuperForester Patricia is living in the jolly Ol’ UK and regularly sends me emails of such astounding quality and clarity that I eventually said: “Look, I could keep formatting these, or you could do me a huge favor and join Team SuperForest.”

And I believe that she’s accepted? (Patty, if you accept go on and say yes in the comments, cool? :))

Check out this radness:

“Happy Monday SF!

Just a quick note as I saw this and thought you might get a kick out of how the SF Way of celebrating the positives rather than focusing on the negatives is more effective in encouraging people to take action / change habits…

New Scientist: “Positive Thinking for a Cooler World” & “How Psychology Can Help the Planet Stay Cool”

It’s a short article and editorial talking about how positive encouragement works better than overwhelming people with the scale of problems, and how a ‘community’ message (well, they says ‘conformity’ with your neighbours but that sounds so sad) is an effective way of nudging changes in behaviour.

“”In another study, the researchers told households what others in their neighbourhood used on average. High users cut their consumption in response, but low users increased theirs. The problem disappeared if the messages were reinforced with sad or smiley faces.

    The smileys received by the residents who were already saving energy provided sufficient encouragement for them to keep doing so

Seriously? A smiley face is enough!? Imagine what an actual real life smile could do.

The fact that positive encouragement can be *better* at encouraging change on a personal/community level than doom’n'gloom?
Writing it down like that seems absurdly self evident… But it took the scientists this long to catch up, so I don’t feel too bad ;)

I am kind of surprised though – surely you have to be educated about the, admittedly scary and negative and serious, issues to even think of changing them?

I dunno. But I’ll take a smiley face with it.

Love,

P”

Righteous! Using positivity to try to change the world totally works!
Thank you very much, Miss Patricia!

Can’t wait to hear more from you soon!

Love,
