My politcally incorrect branding plan.

March 24, 2017 — leslie dean brown

Here’s the thing, I know I shouldn’t mention politics where business & branding is concerned.

I *know* I should be more politically correct. But quite frankly, I don’t care. Or I do care somewhat, but I don’t let that stop me… I see icecaps are melting and still no one says anything through official channels. I don’t see any designers criticising Porsche for making their gas-guzzling 5.0L V8-engined Cayenne for example.

Yes I see all the other designers and creatives and their ‘approach’. And I think 99.9% simply prefer to remain silent.

But I don’t see too many designers with a science background. And my science background CANNOT allow me to sit idly by and “say nothing, do nothing”.

The truth is, our lifestyles impact this world, greatly so.I’m even having a hard time convincing my psychologist of this fact. I think she seems to think that we are all “equally to blame”.

I’m sure other people absolutely cringe when they see me always sharing things about the environment on LinkedIn. But quite frankly, if I lose people’s business as a result of being politically incorrect, maybe “it wasn’t mean to be”. I don’t want to help people ruin this planet. I want to help make it a better place.

So my branding plan is this: what I lose in being politically incorrect, hopefully I gain elsewhere by genuinely being committed to the environment. And if only half the number of art directors woule like to commission an illustration from me, well that just means I’ve got to be twice as good to make up for it. So the quality of my drawings goes up. Right? What’s wrong with that?

I would really like to see other designers and creatives be more vocal. Forget being politically correct. Be brutally honest for once. Have the confidence to know that your work is good enough to lose a few clients to be able to sleep at night.

If you know a product is crap, perhaps more people should say so? I won’t work for fossil fuel companies. Well I would, only for about $800M. I hope people see that ethos is part of my brand.

Characterisation of Australian opals

February 13, 2017 — leslie dean brown

If you’d like to read all about the structure formation of natural opal, this is one of the most complete models of opal formation available anywhere.

At the time I remember my supervisor said to me that it was one of the most well-presented theses that he had ever seen. Not necessarily the results, but the quality of the illustrations and I guess you could say the “design layout”. I guess I always want to be proud of my own work and do things to the best of my ability:

This is my PhD thesis, from 12 years ago.

Today I was able to open up my original word document file that was almost 12 years old. To my surprise, it kept the original formatting and page breaks. And why shouldn’t it? Although I am not so keen on the changes that have been implemented to Microsoft Word between since then.

Okay so truth be told, the original word document came in at 281 pages and the printed copy came in at 282. So something was not right. It turns out that one graph had to be pushed down by one line and the original date was also restored. I was so paraoid that I would forget to change the date, the field updated itself automatically.

The reason I am doing this and sharing it again here is that my thesis was finally digitised by the UTS library this week, but the quality ain’t all that great, because it was rescanned from one of the original copies.

So I’m deciding to generate a brand new, clean pdf myself (I never got around to doing that, because I was compeltely over it at the time). Hopefully the google robots will scour my site, find this pdf and index it so anyone can access it.

How to access climate change science journal articles

February 8, 2017 — leslie dean brown

I’m starting to get a bit pissed with people on this whole climate change issue.

Really I am. People are still disagreeing and it isn’t because of the underlying science being wrong or anything to do with that. It’s because their lifestyle is in jeopardy. Or their job. Or their world view.

I can tell you that scientists could not give a toss either way. The thing that matters most for any true scientist is data, getting as accurate data as possible, analysing the data, discussing the data, and perhaps drawing some conclusions based on the data.

A good scientist keeps an open mind. They accept the results. Most research scientists I know are voracious readers. They seek the truth.

So here’s a story. Before I started my doctorate, I hadn’t even read any science papers. I had a materials science degree and I had not really been exposed to this whole new level of academic research. And when I started my PhD, in 1999, science papers were simply not talked about in the general public. So it was all quite new to me.

I also think that during any undergraduate degree, there are plenty enough university textbook to have to read. So I think most undergraduate scientists try to avoid the library as much as possible.

A large university can have 10,000 very nerdy students enrolled in it. But you never see even 1000 people in a library. Right? So the only reason to go to a library when you’re an undergrad, is when you have to do an assignment. Everyone else either works their, is doing a masters, a Ph.D, or they’re a lecturer or professor. I kid you not.

So when I started my doctorate, 4 years after I started my first degree, I literally started to get overwhelmed at the amount of scientific literature out there.

Much of this science research is ‘hidden’. I don’t mean on purpose. I mean, it’s not easily accessible, because much of it is not accessible through the web. Mainly because science was around well before the internet.

Anyway, the point is that you can’t always google everything. There’s a lot of stuff out there that hasn’t even been indexed by google!

So. How to get access to these journals then? Well, if the journal doesn’t have a webpage, they’re mainly accessible through university library databases. And there are many databases, like these.

Most science research is freely available. Meaning, you should never have to pay for articles. Subscriptions to journals only really cost money because they need to be edited and printed. Also, libraries pay for many of these annual subscriptions (well, the most popular ones at least).

So for the measly sum of about $10 per year, the cost of an annual library membership, you too can have access to practically any journal article you wish to read. So the cost of these subscriptions is subsidised by the university. How does a library get money then? Membership fees, university fees, tuition fees, and a mediocre amount of government funding. I suppose.

So the point is that you can fairly easily get access to pdfs of science papers through a library, and you might not have to pay anything.

There is a lot of collaboration between scientists. So you can always simply email one of the authors and they will gladly send it to you for free. Scientists will gladly share pdf articles with anyone and no that is not at all illegal, it’s encouraged.

Note that if you have never been into a library, don’t be afraid. Most librarians are glad to help. If you find a grumpy one, they’re probably just having a bad day, so find someone else and ask them instead. There’s honestly nothing worse than a grumpy librarian.

More and more journals are becoming “open access”, meaning anyone can freely access them.

So here’s a link to the open-access journal “American Journal of Climate Change”, for example:

http://www.scirp.org/journal/ajcc/

Literally *hundreds* of papers freely available if you click on the ‘pdf’ or ‘html’ links, and this is just ONE journal of MANY that are all dedicated to the Earth’s climate.

Or you can simply join any science university library, walk in there and peruse the shelves and be overwhelmed the old-fashioned way…

By all means people can disagree with the findings, but if you’re going to do that and have any chance of winning an argument against a scientist, you should first at least educate yourself, otherwise you’re simply what I call ‘ignorant’.

The true value of biodiversity.

January 26, 2017 — leslie dean brown

Without insects, it has been said that most of humanity would die within a few months. Without trees and phytoplankton and thousands of other species with chlorophyll, we would all die.

Knowing that, I just can’t understand why billionaires such as Bill Gates are so intent on alleviating poverty in the 3rd world above all else. They make that their priority. In my opinion, it makes more sense to me ot protect nature first, and then when we have that sorted, let’s see if this planet can comfortably support more than 7 billion people.

So I think that environment should definitely be funded first. And then people. I have always thought that. Why do I think that? It’s not because I am cruel. It’s not because I don’t like people. It’s because people do not live in isolated bubbles. People depend on nature.

I think most people don’t appreciate this, but there’s another angle to valuing biodiversity (besides being fundamental for our own survival).

And it’s this. We still don’t really know how embryos form and develop. Sure we can characterise each of the stages of blastulation. We can draw little pictures of each step along the way. But it’s a lot harder to know how and why embryonic folding occurs. So what are there are underlying reasons that each stage of development occurs when and where it does?

I mean, it’s not really a ‘miracle’. Scientists don’t accept ‘miracles’ as answers. There are chemical and physical reasons why cells spontaneously split into two halves. A cell doesn’t just split into two because it feels like it. And there are chemical and physical reasons why this occurs. And from what little I have read on the subject in the book “How the leopard changed it’s spots”, it’s not due to the DNA molecules alone. In actual fact, the first splitting of a cell is caused by a concentration gradient that is set up inside the cell’s plasma. And according to this book, it’s due to flluctuations in calcium concentrations within that first cell.

Okay. Now we are getting somewhere. You might then ask, “Well what causes those fluctations then?“. Most likely, I would say, gravity. Because gravity is a force that acts in one direction relatively to a cell. So there are underlying reasons as to how embryos proceed to develop and they are not always to do with DNA alone.

And those are the real answers that science seeks. It’s not good enough to ask “which genes cause which traits?”. A real scientist wants to know how genes work. How do the chemical variations in a strand of encoded DNA produce the morphological changes? Now, I’m only talking very basically about this subject. It’s an extremely superficial discussion. And so if you’re a developmental biologist or a genetic engineer and you’re reading this, you’re probably laughing at me.

Where am I going with this? Well, until we know *exactly* what causes a rhinos eye to form where it does, or what causes a tiger’s stripes, or the forces that shape an elephant’s tusk, well, I think we owe it to nature to protect all of these things. Because they are a vault of information that can unlock life’s secrets. If we knew the answer to that, then we’d have at least earned the title of cleverest species.

Imagine if we could ‘program’ certain trees genetically to display a road signs such as a speed limits with differently coloured bark. Imagine if you could reprogram the tree to automatically change its bark pattern and display a different speed zone at differnt times of the day? That is all possible.

sustainable morphogenesis.

And I don’t simply mean “what genes are found in a rhino or a monkey”. I mean, what is it about those genes that controls protein folding? If we could create our own strand of DNA, could we predict what the resulting organism looks like?

From what little I have read on the subject, it’s not just DNA. The patterns and shapes seen in nature are caused by physical and chemical forces. Because one day it might be possible to make whatever shape we want at the mere press of a button. Imagine if we could simply grow an organic skyscraper. Right now I don’t think we are ready for that.

Just today, I learned that biology may even be taking advantage of quantum effects.

Even then, all these species are beneficial to us in terms of mental health. We also owe it to this world not to simply destroy everything in our path.
