I feel very fortunate to have been born when I did and to have observed the revolutionary change in technology that I have. Things whizz along so fast these days. My father woke me up in the middle of the night to watch man's first moon landing, but the rocket that took man to the moon only had a 16 bit processor and a tiny amount of memory by modern standards. These days we all have far more power in our mobile phones! It's all happened so blindingly quickly!
 
In fact I feel very fortunate to be born at all, as my parents were quite ‘elderly’ when they had me. Dad was 54 when he had me and mum in her mid forties so I'm lucky to be here. Accordingly the environment I grew up in was full of old technology that had been accumulated over many years. We had a valve radios and television that took ages to get hot before they would work. The family camera was a ‘box brownie’ – little more than a black box with a lens and a winding mechanism to advance the film. The film wasn’t cheap so we took each photograph with care, posing and saying cheese! Then it took days or weeks to get the prints back from the chemist! All these artifacts smelt old and musty, but also everything felt frozen in time as though they had been around forever.
 
Then around the mid-sixties I remember my elderly grandfather went through a number of transistor radios, all of which were made in Hong Kong. My grandad was a bit clumsy and used to drop these ‘trannies’ repeatedly. Invariably the case would break and after a few months of being held together with rubber bands and sticky tape, they would be replaced with another which was always smaller and lighter than the last.
 
I loved to take the old radios apart and figure out how they worked. The valves of old had been replaced by small blobs which were transistors. The other components had all been shrunk too, as had the printed circuit board. Even so, every component was identifiable and it was generally possible to figure out which did what.
 
By the time I reached secondary school things started to change a whole lot. My physics teacher explained to me about integrated circuits. Tens or hundreds of transistors were now being fabricated together on one piece of silicon to form whole circuits. These were found in the first pocket calculators. My first calculator, made by Prinztronic cost a fortune but only did +-/* and percentages!
 
It wasn’t long after that I saw the first microcomputer on the television. This was the commodore Pet, which today still looks more like the sort of thing you would find on the deck of the starship enterprise. The Pet seemed unimaginably expensive to a youngster like me, but pretty soon my school purchased a bunch of microcomputers in kit form (NASCOM 1 if you're curious)  and us school-kids were co-opted to spend hours soldering them together.
 
I inevitably found myself working in computers and during the 1980's the IBM PC became the default architecture for most business users. My first experience of these was the Olivetti M24, which was a dinosaur by today's standards but crucially the office had them networked together with this clever thing called co-axial cable. The first time I met with this concept I remember thinking what a waste of money! Surely if two people wanted to work on the same spreadsheet they could copy it to a floppy disk and walk to the next office with it. How wrong I was, which is a recurring theme in my life! Of course from these humble beginnings, networking really took off, bringing us to the Internet and the applications on the World-Wide Web we are all so dependent on today.
 
I'd moved to Spain by the time I saw my first smartphone, a first generation iPhone owned by a friend on holiday from the UK. It seemed so revolutionary at the time, and Apple had clearly got it right - the combination of touch-screen and scrolling GUI was a winner. Now we all have one (or more) in our pockets and think little of it. When you do think about it though, today's smartphones are far more advanced than the communicators used in the first series of Star Trek, which themselves were considered light years ahead at the time. 
 
An example of how far things have advanced is the disdain people have today of optical media, the CD/DVD discs read with a laser, which are now seen as quaint and clunky like the horse and cart of the digital world. With today's Internet speeds it a lot easier to stream a movie from Netflix than it is to watch an optical disk. A laser based tech becoming near obsolete in my lifetime! How amazing is that?
 
You might think then, like the apocryphal story of the commissioner of the US patent office, Charles H. Duell, that everything that could be invented had been invented. (I traced the quote - it was more likely a joke prophecy made in Punch magazine). This couldn't be further from the truth. the 21st century is the age of materials, where scientists are gaining insights as to how to manufacture new things at an atomic and quantum level. Quantum computers are in their infancy but promise to bring unparalleled levels of computing power. Graphene, the single atom thick layer of carbon famed for its conductivity of electricity and heat as well as tensile strength has already made its way into a commercial battery. Though at the moment it is only used to assist and enhance conventional lithium batteries,  it is expected that graphene only batteries will be used in future mobile phones and electric vehicles that will be a fraction of the size of those used today. 
 
So I've seen the world move from valves to the quantum computer in a couple of generations and technological progress is still accelerating. We're living in a world none of us could have envisaged 10 years ago. Who know what the next ten or fifteen years will bring.

On mumbo jumbo We live in a strange time. The Internet has given us instant access to a greater plethora of information than has ever been possible in history, yet rather than serving to better educate as all, the amount of mumbo jumbo seems to have risen rather than fallen. Flat-earthers, anti-vaxxers, homeopaths, folk who swear by the healing power of crystals and Gwyneth Paltrow, all find it easier to get a platform these days.

Now I'm a logical sort of chap, a great believer in the scientific method, which basically stated is that "if a theory is disproved by experiment it isn't true". However there are a few wrinkles and crevasses in my belief system. These are what I want to share with you today.

Take divining for example. It's clearly rubbish as there is no verifiable force that can be detected by a human with a divining rod. However I recall as a kid we had a blocked drain. My father knew a lot about water. He had spent a decade as a plumber and worked for a time for the Water Board. I watched him fashion a couple of diving rods out of an old coat hanger. He than marched steadily back and forth across the garden. Each time he crossed a certain point the rods moved. He dug down a couple of feet, found the water pipe, disconnected it (it was the ceramic sort connected in sections) and found the blockage exactly where the diving rods had indicated. So I know first hand that diving works but I can't explain why. My best guess is my father knew subconsciously where the drain started, and where it exited the property, so he could have been making an educated guess with that information. How he guessed down to the nearest foot is still beyond me.

I know astrology is complete twaddle. But time and time again certain character traits do seem to reoccur in individuals according to their star sign. Leos are invariably extroverts. Cancerians are crabby and have mood swings. Virgos are organised and boringly safety-conscious, Scorpios are the undisputed masters of exacting revenge etc. It seems there are two possible explanations for this. Firstly we learn about our own sign in childhood and it is possible we either subconsciously (or possibly consciously in some cases) grow to fulfil our own prophesy. Another theory is that the seasons may play a role. The younger you are, the slower time passes. Imagine you are a newborn infant born say in September. Your first six months would seem like a life time, but much of it would be cold and grey, whereas if you were born in April those all important formative months would be bright and sunny. Many things other than the weather influence adult moods thorough-out the seasons, holidays and so forth, all of which would be absorbed by the infant. Is it then any wonder that people born at different times of year have a different outlook on life? The only snag with this theory is the character traits in the Southern hemisphere would be six months out of kilter with those in the northern hemisphere, though I still think it is a sufficiently interesting proposition that it warrants further investigation.

What I'm getting at is that for most phenomena considered supernatural, there is usually a more mundane explanation.

And now for a good old ghost story. Clearly ghosts don't exist according to science. However strange things happen. This is one I experienced myself.

Back in Murcia a couple arrived from the UK with the intention of establishing a pub, which they did by converting an old residential property, and a very good job they made of it too. They named it the Yorkshire Rose. It was heaven. Just before it opened, they invited an elderly neighbour in to show her what they had done to the place. She was happily admiring the decor until she reached the far right-hand corner of the bar, at which point she burst into tears. It turned out that is where her friend, the previous occupant had gasped her last breath.

I didn't know this until the story was recounted to me some years later. However I recall dining in that corner of the room and thought it felt chilly. I mentioned it casually to the waitress who laughed and said she had lost count of the people who said that. Stories abound that cold spots like this are associated with hauntings, but perhaps I'm just putting two and two together and making five. Perhaps it was explanable by air-flow, fluid dynamics and the fact that air-conditioning unit was just above my head!

However this wasn't the only spooky thing that happened in the bar. One night, I and a bunch of pals had a late-night lock-in playing poker. It was a bright moonlight night and very still. There was not a breeze in the air we had no music playing, so it was just the flick of the cards and our banter that could be heard. At about 1:30 a.m. there was an enormous crash. My first thought was that someone had thrown a brick through the window. As I was nearest the door, I unlocked it and had a look outside but there was nobody there, and anyway the windows were protected by wooden shutters.

Meanwhile my fellow poker-buddies looked around inside. It turned out that a glass had smashed behind the bar. This was strange, as nobody had been behind the bar for a while as we were all involved in the game. Also the shelf on which the glasses were kept didn't have a direct path to the floor. There were freezer cabinets and cupboards on which the glass should first have bounced, but this isn't what any of us heard. We all heard one large crash, so loud that we all agreed it sounded though it had been thrown down deliberately by a human hand. We got back to the game scratching our heads. I considered things always sound louder at night when it was quiet and dismissed it as a freak accident.

I was in the bar again quite early the next morning as I was due to meet a client there. A different barman was on shift. Thinking the owner may have told him the tale already (but setting my self up to segway neatly into the tale if necessary) I jokingly asked him if anymore glasses had smashed this morning. He turned to look at me, eyes like saucers, the colour running from his cheeks.

"How do you know about that?"

"I was here last night", I replied.

"No, just now. After I opened I was standing here at the sink washing up a few glasses and all of a sudden a glass smashed on the floor behind me. It sounded like someone threw it at the floor - I jumped out of my skin!"

It turned out the owner was having a lie-in and the barman knew nothing of the night before. After I shared the story with him, we did the only sensible thing in that situation and had a couple of nerve-steadying brandies!

Coincidence? Maybe. There are a lot of earthquakes in Murcia. Sometimes these come in swarms and are all but imperceptible, but resonance at a particular frequency can cause individual objects to move while everything around them is still. However, there is a primitive part of me that cannot shake off the notion that not everything is mumbo jumbo. Some things do go bump it the night!
