Recent research on global warming, sea level rise and super storms.

March 24, 2016 — leslie dean brown

If there’s one video I think you should watch today, it’s this one. I think climate scientists in particular have a special “duty of care” to humanity. I wholeheartedly suggest that all climate scientists boycott fossil-fuel powered cars in keeping with their discoveries and the changes we all must start to make on an individual basis. I think it may show the general public that they are prepared to make some sacrifices for what they believe in.

As I stated previously, I personally no longer own a car — but I do use (borrow) a car about once a week now. Since I sold my last vehicle, I am able to donate more money to environmental charities with the money I save on fuel, insurance, upkeep and everything else… I have actually donated more money to charity than I have spent on fuel so far in 2016. I think more people need to do that.

I really don’t think it’s wise to put all of our trust into current politicians. I firmly believe that most of the mainstream parties do not have our own long-term best interests at hand. I also think that the two very traits that have put us where we are today, namely, our anxiety and what I like to call our “social intertia”, may well be our undoing as a species.

What we can learn from North Korea.

March 23, 2016 — leslie dean brown

I’ve noticed lately that a lot of Western video productions are unfairly biased about North Korea.

So Western journalists have a big gripe about not being able to film certain parts of North Korea. But North Koreans, okay, like all nations, want to be portrayed in a good light. Because North Koreans are smart enough to know that some journalists are unscrupulous…

What if I made a video documentary about Sydney and filmed all the homeless people, the junkies, the graffiti, the rubbish, the wastage, the consumerism, the violence, the poor distribution of wealth, the relentless urbanisation, interviewed all the aboriginal people in our jails, filmed the chopping down of forrests in the Laird state forest to make way for a new coal mine? Well okay.

But what if the Tourism Industry Association of New Zealand came to Australia for example and then used that to infer that “New Zealand was better”? Maybe we’d be able to take it like a joke (even if it were all true).

But I am pretty darn sure that if our tourism industry was proven to have suffered economically because of that documentary, then we’d promptly ‘react’ by banning such films. I’m sure the Sydney council or tourism board would stop people filming the dirtier parts of town. And I wouldn’t really have a problem with that. It doesn’t make me ‘evil’. [Read more…]

The consequences of scale.

March 22, 2016 — leslie dean brown

One thing that I don’t think many people reaslise on a day-to-day basis is that changes happen at all scales and their effects can be felt across all scales. The macro scale affect the micro scale, and in turn, the micro scale can affect the macro scale.

For example, an entire field of wheat can be killed at the cellular or molecular level by spraying it with chemical toxins. This results in the disappearance of a visible thing on a bigger scale. The dead wheat then decomposes, a result which later manifests itself as changes in the soil chemistry. When wholey other different large-scale changes subsequently occur, replacing the field of wheat with something else, that again then affects the visible scale. These micro- and macro-scale responses and consequences can continue to alter themselves in this manner until reaching equilibrium. All events are related together and caused either directly or indirectly by each other.

These perterbations continually fluctuate and influence each other across vast differences in scale.

Although what I am saying is that things like gravity may well be a particle (I don’t even know, not my area). Atoms are composed of sub-atomic particles. So cause and effect always works both ways. ;-) large cause —> small effect small cause —> large effect I am not arguing for the butterfly here causing any significant observable phenomena. I’m just pointing it out that it’s not always “top down”.

Since understanding the Navier–Stokes equations is considered to be the first step to understanding the elusive phenomenon of turbulence, the Clay Mathematics Institute in May 2000 made this problem one of its seven Millennium Prize problems in mathematics. It offered a US$1,000,000 prize to the first person providing a solution for a specific statement of the problem:

Prove or give a counter-example of the following statement: In three space dimensions and time, given an initial velocity field, there exists a vector velocity and a scalar pressure field, which are both smooth and globally defined, that solve the Navier–Stokes equations.

Furthermore, I also think that large-scale effects are always caused initially by small perturbences. What I mean by that is that every event in history is caused by a smaller, prior event. Some of us like to think that this is not the case, and that only large-scale changes can only ever be the result of even larger scale effects. But I think if you have read about chaos theory and the term “sensitive dependence on initial conditions”, then you’d probably agree with me. Say I hit something with a hammer. You might think that the hammer causes large scale changes in whatever it is that I destroy. But what made me decide to strike the hammer in the first place? Wasn’t it really caused by some of my neurons? Perhaps if time went backwards, then it might be the other way around, but I’d rather not get into that, because the last time I read about about that, I thought the author was a bit loopy.

Why I decided to quit facebook.

March 17, 2016 — leslie dean brown

In recent news, I just quit facebook. I quit because they are encouraging trophy hunting by allowing their pages to remain online. I believe they could do so much better with animal rights and conservation issues.

Nothing happened. My head didn’t fall off. I enjoyed real life more now. I am happier and much more productive.

I have even started this petition to get more people to quit facebook as a form of protest and defiance.

Mark Elliot Zuckerberg,

The first time I logged on to the internet, the year was 1995. I had to go into a special room at university to access it. Only about 30 computers were connected to the internet for students to use — in the whole university.

A few years later, more rooms appeared throughout the campus. I remember one day in particular. My college buddy could only find a handful of Porsche images *on the whole internet*. I can even remember him printing it out. It was so rare to him it was like a prize. I remember because we had to take turns — using the same internet connection!

Four years later, in 1999, I got “into trouble” for using the internet at work! Yes. “People can see you” he’d say. I had to show my boss that I was searching for material properties online. He promptly wheeled his office chair over. He had called my bluff. And I pointed to the screen. “See?” At that time, people didn’t use the internet for work. No.

I don’t know when it was exactly. I was still at university. All I can remember was that the internet was still fairly ‘new’. The average person still did not use the internet on an hourly or a daily basis (except for email). Anyway, I got this weird “friend request” from this unknown person calling himself “Mark Zuckerberg”. It wasn’t one of my friends. I’m pretty sure it was actually you.

If memory serves me correctly, Mr. Zuckerberg, you actually came to me. I certainly never went out specifically looking for anything like facebook, because I was a nerdy anti-social science graduate. You probably found my email or something.

I decided to accept your initial “friend request” and sign up to this new facebook thing. And because I was introverted and shy, I never really bothered to say anything to you. It was when there was only a few thousand facebook members *in the whole world*. At the time I can remember thinking: “what harm can it do?”. Nobody I knew had a facebook account. I repeat: nobody. And so it began…

High definition destruction

March 17, 2016 — leslie dean brown

It always amazes me how all of these latest technologies showcase *nature*. I find that quite ironic. I find it ironic because we get the copper and other elements that are contained within electronics from mines. And it is frequently places like the forests in Papua New Guinea that are mined to get these elements.

What is the point of high-definition television, holograms, visual special effects, if we are just going to watch the destruction of nature in ever-greater detail? Or fake representations of nature? I can go outside and see it in higher definition than any screen will be able to display. It’s called “atomic resolution”. I.e. real life.

I don’t understand people. Watching nature makes us happy. As we distance ourselves further and further from nature, we think that we can live separate from it. Nothing could be further from the truth.

Yet most of us carry on our daily lives almost in fear of the natural. We go on poisoning it. Controlling it. Dominating it.

What is the point of faster or more comfortable airlines if the destinations are not as pristine as they used to be?

What is the point of creating high definition televisions, sharper lenses and ever-more megapixels, if we’re only going to witness the destruction of nature in ever-greater detail and clarity?

A common observation is that nature provides much inspiration even for 3D models. So I encourage people to donate to environmental charities instead of buying the latest technologies all the time. Half the reason we are in so much shit with the planet is because we have forgotten how to give back to nature. We are always taking and never giving back. So I encourage you to stand up, speak up . That way, you might *truly* feel better about ourselves, our civilisation, instead of feeling this ‘guilt’ for what we are doing.

The truth is, unfortunately we do not value nature as much as we should. We do not see the work that it does for us. Trees create oxygen for us for free. If we had to extract our own oxygen from carbon dioxide, how much do you think that would cost us?
