Sounds of Science

Ahh! I have so much I want to write about. None of it is particularly exciting, life's been boring - just the standard UCT adventures and drama. Also, either I haven't been reading enough or there's just nothing exciting happening in the world, but I haven't been coming across any cool stuff to share and blog about... but I need to start mixing it up more because this blog can't be allowed to stagnate into a bunch of personal rambles. Especially since I've actually got readers now thanks to my dad's publicity (thank you pa) :P That said, this one is again about my life and not about some specific issue and it's going to be rather long to compensate for the lack of writing otherwise. So where to start...going to try and go about it systematically.

I've really loved varsity this week. We've started the "Ecology of the Individual" section in Ecology, currently busy with this amazing section on parasitism. Learning so many amazing new things...like for instance - I've seen documentaries about the candiru - a small parasitic fish in the Amazon that's been known to swim into people's genitals, for lack of a better description. But it's only this week that I learnt why. Candiru generally like to attach themselves onto the gills of other fish because they thrive on some of the waste that's expelled from the gills. One of these waste products is urea so that's why they swim up people's urethras, the urea confuses them. Quite interesting I think :) As for the practicals in ecology? Currently we have none, our prac afternoons consist of watching episodes of BBC Life in the zoology labs :) And when we do have a proper practical, it'll be in the form of a five-day camp next week doing all sorts of exciting fieldwork. Definitely a course that I'm happy with. 

EGS has been amazing too. Frank Eckhardt is an amazing lecturer. He knows how to teach things in a manner that grabs your attention and interest. He's just finished teaching us on tropical environments and has now moved onto arid environments. He's brilliant. The images and videos he shows us are always so eye-opening. Which makes me realise - I lied in the first paragraph, I do have exciting things to share. Firstly, some PHENOMENAL interactive before and after satellite imagery from the Japan tsunami. Play around with the slider on the images, it's so shocking but such amazing use of technology. And wow, if anything demonstrates the sheer power of nature, it's these pictures. The other amazing thing is Yann Arthus Bertrand's Earth from Above photographs - "An Aerial Portrait of our Planet towards Sustainable Development". Just take a look at the website (quite intense music plays when you open it, so dramatic), I put some pictures up but they're all copyrighted, there's lots more on there :)

I first heard about him last year during Teamwork's Bonjour India festival, he was showcasing his photos along a famous road (I forget the name) in Mumbai. But this is the first time I've seen his photos, thank you Frank Eckhardt. Incidentally, he also took the photo that is my current Google Chrome skin. What I love about his pictures is how they give you a completely new perspective on the world we live in. The best way I can describe it, it's a bird's eye view of 1) how beautiful our planet is, 2) how advanced human society has become and 3) put 1 and 2 together and you get an image of how we have destroyed and continue to destroy so much of the Earth. When I look at human civilisation from this angle, I can't help but think of this line from the 11th Hour that describes us as a disease, "Our biosphere is sick and we have a planet that's behaving like an infected organism. If you look at it from outer space, you see all these lights, the lights of these people... it's like looking at an organism with some sort of infection on it". But James Lovelock puts it best - "We have grown in number to the point where our presence is perceptibly disabling the planet like a disease. As in human diseases there are four possible outcomes: destruction of the invading disease organisms; chronic infection; destruction of the host; or symbiosis - a lasting relationship of mutual benefit to the host and the invader."  It's an analogy that appeals strongly to my biology-centric mind. Anyhow, such moving images.

Back to the writing, oceanography continues to disappoint me, which is really sad news. I've always been fascinated by the marine world and how the properties of the ocean have the power to shape the whole planet. They're such a powerful force on Earth and the most appealing thing about them is that they're so vast, there's still so much more to learn about them. But god, I didn't realise how complicated this stuff would be to learn about. Memorising maps of heat flux (I still don't know what the term even means) patterns, knowing all these abbreviations like ABFZ, NADW, AABW - names of different currents, how weather patterns link to ocean circulation, the list goes on and it's all so complicated and intricate. It does give me a greater appreciation for oceanography, but it really deters me from pursuing the subject. Buuut like I said before, I need to do this course because it's got some really important foundation information and it'll be a great background if I ever want to do atmospheric science or marine things in the future.

The GCI is as exciting as ever. I love being involved in the COP17 project. There's so much scope. So much we can do as the student voice of South Africa. And we have the whole year to prepare for it. It's so rewarding. The Earth Hour project hasn't been as great, the planning has been happening very quietly, I don't really know what's going on there...but as I write this, Earth Hour is in exactly one week. As I've mentioned before, this year, the message of Earth Hour is to "go beyond the hour" and do something more than just switching off for the hour. Basically, as an individual you should commit to another ongoing action that will make your life most sustainable... I'm trying to decide what mine will be. I'm thinking of committing to sustainable transport - more public transport/carpooling/walking, but that's something I already am doing so I guess I just need to take it further...I'll make a pledge later in the week :)

Another great that happened at varsity last week was this series of lectures by Dr. Tom Woodward, head of the C.S. Lewis Society and strong advocate of intelligent design (the theory that it was an intelligent being, not nature that created the universe and life, a theory that I obviously find highly offensive). He did four talks starting with a general introduction on life and its place in the universe and how intelligent design is the best explanation for what we see on Earth, then moving onto the subject of DNA, then the fossil record and then a final one on genetics which I missed. The first one was great in getting everybody angry at him, highly contradictory, he provided no productive arguments for ID or any information or evidence. In fact, he did so for the whole lecture series. The DNA one was basically "a really bad genetics lecture" in Kyran's words. I completely agree, he spoke no sense. And he referred to the amount of information in a chromosome as so complex that it must be something supernatural. So insulting. Worse than that was the one on the fossil record. It was hilarious attending it with Nick though, someone who specialises in paleontology. Their anger may have been the highlight of the talks actually... I went to the talks to learn about how ID people support their theory but I got nothing from Woodward, learnt far more from Ky and Nick. But I'll write more about this once I feel confident enough on the subject to dedicate a whole long post to the cause of evolution :)

Outside of varsity I've been accumulating a great collection of nature documentaries. I just got my hands on BBC Life, I got a whole bunch of amazing stuff from Nick, I've got BBC First Life which I need to finish and of course - I'm currently busy with season 3 of Whale Wars. There are three ships in this season, and I love all the different crews, each has its own character. I'd love to have been on the Bob Barker. Anyway, it's a captivating season of campaigning as always. As for BBC Life. Wow. I highly recommend every single person alive to watch this series. If there's anything that makes you see the beauty of life and the wonders of evolution, it's BBC Life. From what I've seen so far, some moments that stand out - the life of mudskippers in the fish episode, from the Hunters and Hunted episode the ibex-fox chase, the star-nosed mole, the stoats, dolphins and Ethiopian wolves. And of course one of my favourite bits of footage EVER, from the primates episode - Brazilian brown-tufted capuchins which over the years, have figured out how to open impossible palm nuts using tools like hammer stones, determining which kind of rocks are right to use. The intelligence and the way they go about problem solving is just brilliant. Another amazing one from the Hunters and Hunted episode was the ground squirrels - they chew up bits of shed snake skin into a paste which they then rub into the fur of their young so that they smell not like prey but like rattlesnakes - mind-blowing.

Another cool little thing that's been happening outside of varsity - as I write this I realise it's not that cool, it's really quite mundane but I find it exciting - I think there are geckos breeding in my bathroom. I'm coming across these TINY ones on a daily basis. I'm so annoyed because I still can't be sure of what species they are. I'm thinking Marley's Flat Gecko but I'm not 100% sure and I still haven't found a nice adult to look at. Very keen to find out where they're coming from though, maybe I'll find the parents... it's great though because it's given me a lot of confidence in catching them and handling them :) For those of you that don't know *confession moment*, I have quite the phobia of insects/creepy crawlies in general. Yes, let's all laugh at nature girl with her bug phobia. I don't know when it started...I used to collect and play with caterpillars and things when I was younger. The geckos don't fall into the phobia category because I absolutely love every kind of reptile, but I was still quite iffy about catching/handling them myself. I've realised that if I'm in a controlled environment where someone else (a professional) gives me any animal to handle, I can do it - I've held tarantulas, rats, so many reptiles I've lost count, birds, everything. But as soon as it's just me and the animal one on one I get nervous. In the case of the reptiles, birds and mammals it's mostly because I don't feel confident in holding it, I feel scared I'll do something wrong or upset it - which I have, I've been bitten by lots of little guys. But with insects it's a different story...I've established it's their unpredictable movements that bother me most. My worst ones are praying mantises, grasshoppers/locusts, crickets, christmas beetles, bigger moths and of course cockroaches - absolutely terrified of them to the point that just seeing one can bring me to tears like a little girl. It's embarassing. Getting rid of it is one of my long term goals...how can you claim to love nature and yet be so terrified of a group of animals so vital to understanding and appreciating the animal kingdom? Pathetic.

In even more news, I spent the whole day at the beach with Tara yesterday. It was an absolutely stunning day. So refreshing. I feel honoured to live in a city as beautiful as Cape Town. While lounging on the beach, I started reading James Lovelock's "Revenge of Gaia". I didn't get very far but I did find some quotes that spoke to me so I'll jot them down here and then stop rambling, they're from the foreword by Crispin Tickell.

"As has been well said, the first requirement is to recognise that the problems exist. The second is to understand and draw the right conclusions. The third is to do something about them. Today we are somewhere between stages one and two."

"We are currently trapped in a vicious cycle of positive feedback. What happens in one place very soon affects what happens in others. We are dangerously ignorant of our own ignorance, and rarely try to see things as a whole. If we are eventually to achieve a human society in harmony with nature, we must be guided by more respect for it."

Oh and I'm still confused about what field I want to specialise in. But I won't start on that now or I'd go on forever.

Eish, that's enough. What a long post. I don't know how I managed to write such a positive ramble considering I'm currently in a state of severe irritation and pain from a sprouting wisdom tooth. Not an aspect of evolution that makes me happy. It's a long weekend, a supermoon tonight and easily one of the hottest nights I've experienced in Cape Town. Good night :)

  1. I stumbled upon this blog by chance, and am now loving the posts and images! And Gaia is an interesting way to look at the environment; its unfortunate that intellectuals have often ignored it citing a lack of merit and reasoning.

    Keep posting!

  2. Hi, thanks! Will keep them coming, especially as I finish reading Revenge of Gaia ;)
