In the future we will engineer termites to build skyskrapers.
Yes. In the future, I can confidently predict that we will engineer termites to build skyskrapers.
Because in the future, we will start to realise the power of “bottom up” systems of engineering. Currently, we do everything from a “top down” perspective. What does that mean? We start with a mine, dig that up, we then crush and grind the ore down, melt it, form it into large slabs of metal which then get progressively smaller as they are processed. Yes, we even obtain the metallic powders that are used in 3D printing this exact same way. This is a most inefficient process.
Nature does it the other way around. It uses local materials obtained from trace chemical elements and is then able to organise, redirect and assemble those individual atoms and molecules to build its own structures, in situ. It does this without any “larger scale” instructions or guidance. And it is able to replicate itself on top of that. So the more I think about it, the more evolution amazes me.
I read this fascinating book in 2014 called “Emergence”. And one of the traits of nature is that it has “emergent” properties. What does that mean? It means that complex systems or behaviours can arise from relatively few simple rules. In other words, it is “self assembling”. Organisms can do their own thing seemingly without any intererence from the outside world. Wouldn’t we like to be able to do that? Here is where we are currently at:
The other marvel of nature is that everything is an “ambient temperature process”. Think about that for a moment. Practically every synthetic material we produce today requires some form of heat to manufacture. Metals must be smelted. Ceramics must be fired. And plastics must be obtained by “thermal cracking” of crude oil. Sure there are a few exceptions, such as sol-gel technology.
Imagine for a moment a “homogenous” material with different chemical, thermal, electrical and physical properties along its length. In other words, a single material that was flexible at one end and rigid at the other, without being formed from two separate raw materials. If we could get that to happen, spontaneously, then I think we would be quite a clever species. Because an invention like that would literally change the world.
Imagine tyres that increased their coefficient of friction and gripped more in the wet. Or indeed, slicks that morph into treaded tyres in the presence of water. You see, from what I have read, I think all of that is ‘theoretically possible’, but the more biodiversity we lose, the less chance there is that it will happen. That is why protecting biodiversity is so important, so we can understand how genes work to create any morphology and material properties we desire.
Is a ‘circular’ electronics industry possible?
What this angry scientist has to say about climate change:
Here I go again… why am I angry? Do scientists even get angry? Yes. Yes they do. Well I am angry. Very fucken angry!
I‘m angry at politicians in the mainstream parties. Because they aren’t doing enough to mitigate an environmental catastrophe. Most politicians today only care about one thing: money. The economy. Whoop-de-doo.
Scientists, if you remember from highschool, are the clever people. They are the nerdy ones with poor social skills. You’d think most countries would be run by the smartest of individuals. Are they? No. See, I think that’s where we’re going wrong. Our countries are run by politicians.
Likewise, I am angry at climate change deniers. Because they are now claiming that “climate change is a government conspiracy” (right, well if that is true it has to be the dumbest conspiracy theory I have ever heard, because the governments are the ones who support burning coal for fuck’s sake!).
Actually, I lie. Half of it is worry, not anger. For example, what’s actually worrying is that some people think an average temperature increase of a couple of degrees in only a few decades is at all “natural”. What’s worrying is that some people still don’t seem to grasp the concept of “rate of change”. I have seen on LinkedIn that the biggest climate change deniers are frequently either working for oil companies, have a vested interest in contruction, or are simply “uneducated fools”.
I find some people’s responses to climate change infuriating. Scientists are (mostly) a VERY clever bunch of people. If climate scientists are ringing alarm bells and making videos like this one, it’s enough to make me pay attention and completely change my lifestyle.
Right. I’ll say that again, but in a different way, because it bears repeating. Because I know that people skim read things. When the leading climate scientist, James Hansen, says (back in 2012 mind you) that “we have a climate emergency“, well, it’s enough to make me sell my vehicle. It’s enough to make me think up a new career choice, about how I can make the world a better place for future generations to come…
In science, we have to have a kind of ‘faith’ too. Scientists have faith in other scientists. We mutually respect each others’ fields of expertise. If I were to say, as a materials scientist, that magnesium has a hexagonal close packed atomic structure, I would hope the other scientists would give me the benefit of the doubt about that. And that is how the whole science community works. Things are checked and rechecked. Publications are reviewed. These people are working on these problems their whole lives. [Read more…]
My letter to Maurice Blackburn [PART 2]
PART 2
[continued from part 1]
As a former scientist, knowing what I know, other forms of much more sustainable energy exist and yet the government allows this to continue. The WHOLE scenario is woefully depressing. That is basically the catalyst for my chronic ‘melancholy’ depression. The total lack of global accountability and responsibility to future generations to come…
Two decades ago, there was hope. Now, because of the reluctance for industry to change, I am fast losing that hope. Indeed, the situation is almost becoming ‘hopeless’. I just read that Australia has enough brown coal reserves to last another 465 years. Now WHO DOESN’T find that figure morbidly depressing I wonder? Who fuckingwell doesn’t? Eh?
I don’t want to live in a world that contributes to a worser future. I don’t want to use their dirty electricity. But what choice do I really have? I know that even if I buy ‘green’ electricity, the very same energy company supports fossil fuel companies.
I don’t want to pay taxes while all of this all continues. What’s the point? What’s the point of even working? Aren’t we supposed to be working for a *better* future? Well many people are working on it, on renewable energy technology like solar & wind power, yes, but some of these big corporations should have to pay. They are directly affecting my mental health right now.
The government has a duty of care to protect us. They aren’t doing that properly. Mining companies also have a duty of care to ensure that they won’t jeopardise our health or the future of this planet. They aren’t doing that properly either…
I’m willing to bet there are tens of thousands of people like me… if you want to find them, start with scientists. Start with climate change scientists, ecologists, even farmers, people like that.
Sincerely,
Dr. Leslie Dean Brown.
(ex materials science researcher)
P:S I’d appreciate it if you could CC me Part 1…
unfortunately I lost that and I’d like a copy of it to put on my blog.
