How to build a green roofed garden store

Since I laid out my slate patio a few years back I’ve used it less than expected. I realised lack of storage was one reason for this. Along with the inevitable broken flower pots and recycling bins, the odd bag of rubble or scrap of wood temporarily parked until the next recycling centre trip was giving my back garden a builder’s yard vibe!

Instead of storing my rubbish in an ugly plastic box, I built my own green roofed garden store. I chose Sedum turf instead of wildflower because although both encourage pollinating insects, as Sedums are semi-evergreen they give you something to look at through the winter as well as summer.

Climate change, anxieties and actions

This summer’s heatwave through Europe and Asia was one of many extraordinary weather events, which along with forest fires, storms and flash floods, are becoming less extraordinary every year. Scientists are not claiming direct cause and effect for individual weather events, rather there is a very simple principle at work – CO2 and Methane put more energy into our weather systems. The more energy goes in, the more energy comes out, with greater frequency and intensity of extreme weather events.

The IPCC October 2018 report and the ‘hothouse earth’ report that rounded off the summer both re-state that climate change may become irreversible, but with the worrying twist that the tipping point may be closer than previously thought. There are more frequent warnings that we really could leave Earth permanently damaged for our species, perhaps within a few generations.

Such headlines grab the attention for a time because our hunter-gatherer brains are hardwired to monitor for immediate threats. However as the solution requires action outside of our control, what remains is often a sense of powerlessness.

Those of us who grew up in the shadow of the nuclear arms race lived with a similar sense of anxiety and powerlessness. Every childhood from the 1950s to the 1980s came with the realisation that the complete destruction of everything you love is an ever present man-made threat. The adult world is dominated by a love of abstract concepts – political ideology then, short term profit now – which become more important than life on this planet.

Yet, despite our species many flaws, we have to focus on the positives and believe our species has a strong enough instinct for self preservation to avoid complete catastrophe.

Is subjective experience the answer to the consciousness problem?

traditional view of humans at top of species pyramid

Humans are considered the only truly conscious animals, because we are not just reacting to our environment but we do so through a rich complex inner world. However I think this complicated, self aware, highly subjective experience is just one type of intelligent awareness. In fact as I will argue here, there are even parallels between our subjective experience and a legacy computer system.

Most people would agree our species sits at the top of the evolutionary tree, the apex of the pyramid perhaps, because we have the most complete, even enlightened awareness in the animal kingdom. Analytic thinking, self awareness, subjective experience and so on, were long thought to be uniquely human traits, which makes their appearance in just one species an ever greater mystery.

Why do people catch a yawn?

No, don’t yawn. You’ll set me off…..

As infectious yawning is only found in apes and humans, the unanswered question of why we do it keeps drawing in the research dollars. Consensus seems to be settling on contagious yawning as a form of social bonding. But I wonder if our hunter-gatherer ancestry means there’s more to it than a symbol of simple social cohesion, unrelated to sleep?

Two non-problems of modern philosophy

There are two questions in modern philosophy, which I believe are largely created by a failure to compensate for the nature of human perception.

The (non) hard problem of consciousness

Philosophers like Daniel Dennet who treat this a non-problem, believe the question will eventually be resolved by more research into the brain itself. I have a slightly different take. I believe by asking this basic question about subjective experience; ‘how does seeing the color blue create the sensation of blue?’ David Chalmers is really asking (in a metaphysical not neurological sense) where do sensations of the external world finally end up?

Video release

After some months of work, I’ve boiled down the content of three previous blog posts on the measurement problem and consciousness into a 28 minute video.


(or on Vimeo https://player.vimeo.com/video/247760088)

The video and blog posts came about because modern science still treats the existence of consciousness in a world made only of atoms and energy as unexplained, even mysterious. Some 25 years after first hearing about the measurement problem, I’ve still not come across a credible account of these things using a scientific or materialist panpsychism. Possibly the word itself is the root of the problem – it just sounds as if Ouija boards must be involved! Advocates of philosophies like panpsychism do sometimes promote unproven ideas, like telepathy or astrology, which may undermine otherwise valid arguments for the scientific community.

However if you properly examine our concept of consciousness in the light of recent scientific research, Continue reading…

BioDiesel. The Good, the Bad, and the Chippy

I do around 2000 miles per year by car. To further reduce carbon emissions and air pollution I’ve been filling up my Golf Tdi mk4 with recycled food oil biodiesel. Crops grown for Biofuels compete with food production for land and water. However recycling food oil into fuel should not be dismissed as it reduces carbon and generally burns more cleanly than standard mineral diesel.

In use I’ve found no loss of power and the engine runs as smoothly as before, if not slightly better. Because biodiesel contains more Oxygen and cleans deposits from your fuel system, it’s recommended to change the fuel filter after the first 1000 miles. My 2002 Golf Tdi is well suited to running 100% biodiesel. Continue reading…

Frequent fails of barefoot shoes

What’s a long distance to run? 10,000 metres? A marathon? A 100 mile ultra-marathon in mountainous terrain, barely stopping through day and night for 20 hours?

There is a growing opinion all humans are capable of running several hours and covering tens of miles daily. Over long distances humans are the fastest animal on the planet because we lose heat efficiently, making us the supreme ‘persistence’ hunters as we pursue our prey to collapse for an easy kill. Humans have only made tools for around 200,000 years, so for the first 1.8 million years of human evolution, the ability to run long distances was a probably a key factor preventing our extinction – before large brains and the ability to change our surroundings really gave us the evolutionary leg-up.

Long distances used to be shorter

In 1972 my father watched an athletics event in Edinburgh, where a mix of Olympic hopefuls and lower ranked amateurs were competing. In the 10k the slower runners came in long after the podium places had been decided, but everybody stayed and cheered the stragglers home, feeling that anyone finishing a 10,000m run was achieving something special. At this time distance running was to the general population a bit eccentric and unnatural. It was the same for many scientists, Continue reading…

10 WordPress plugins for a writer’s blog

WordPress is an excellent tool for getting your writing online, but as a web programmer I know that it lacks some important features ‘out of the box’. When I set up this site I immediately added ten free WordPress plugins to get the basic functionality all good websites need.

Here is my list of ten essential WordPress plugins for any writer’s blog, which I’ve divided into three groups; QA, Extra functionality, Security and utilities. Continue reading “10 WordPress plugins for a writer’s blog”

The consciousness gap and physicalism reloaded

japanese style wave patternHow real is your existence? Is your world constantly re-inventing itself around you? Or is human life no more mysterious than an actor playing a part on a lifeless stage set? Science is well equipped to account for all the matter and energy around us, from the the Big Bang onwards. Yet the most important tool in understanding our world, consciousness itself, is so subjective and potentially unscientific we struggle to account for it. As a consequence science lacks an account of how conscious beings, humans and other animals, can be composed of nothing more than the atoms that compose the unconscious inanimate world that surround us. It follows on from David Chalmer’s idea of the hard problem of consciousness, and I am calling it the “consciousness gap”.

In common with most scientists, I believe our consciousness is a direct product of matter and energy and cannot exist without them. As an atheist I agree our existence and behaviours can be largely explained by evolution, mathematical biology, chaos theory etc, all without reference to supernatural forces or an intelligent creator. Physicalism, materialism and naturalism give us the best explanation of our world to date and largely do so without mythologising human existence.

Yet science cannot bridge that consciousness gap in a way that is useful to our hunter-gatherer brains without some account of how living consciousness comes into being. Continue reading…

Public transport – an alternate route?

bus graphic

Public transport is the most efficient way to move people around our cities, so why is it not more widely used? In many UK cities people use their public transport unwillingly. Increased privatisation has not fixed the problem. Outside of London bus passenger numbers have been in sharp decline since 1984/85, down 37%. And privatisation continues – the (ironically delayed) 2017 Bus Services Bill introduced a wholly ideological clause to stop local authorities running their own bus services, even if that service is more cost effective than a privately run service.

Efficient public transport is vital to our environment and our economy, and I believe our overly privatised buses and trains are failing on both counts. Here I’m going to suggest a way to enable low cost public transport across the UK to improve our environment and increase passenger numbers. Continue reading…

Cancer is a lottery, not a judgement

dice_pink_background

Cancer is a dreadful illness. The conventional treatments can be harsh and unpleasant to endure, and perhaps there should be a better way. Many people have claimed the power of thought prevents and even cures Cancer, some of whom have themselves survived Cancer against the odds. But before anyone puts their faith in such claims I think there is a statistical point to consider.

According to Cancer Research UK, worldwide there were 14.2 million new cases of Cancer diagnosed in 2012. If all those 14.2 million people had been given the very worst prognosis by their doctors of only a 1 in 100 chance, that still means 142,000 of them would likely have survived, and half a million would have seemingly done the impossible by 2016. Fortunately the actual odds of surviving all types of Cancer averages out around 50/50 over 10 years.

So for every person who can testify to their thoughts beating the disease, there will be many more making no such claims, and many more who sadly will not make it. It’s an obvious point maybe, but only those fortunate enough to live through Cancer are then around to write an inspiring book, make a video, or charge for a ticket to their seminar on how they believe they did it.
