I’m back

It’s been a while since I posted and much has been happening including a fair bit of travel. Anyway I will be posting regularly again from now on.

I’ve finally completed the third book in the Broken Empire trilogy (The Empire of Madness) and am editing it at the moment with a view to publishing it on Amazon in a couple of months. The first two books (The Bear Keeper’s Daughters and The Mistress of the World) are available at https://www.amazon.com/Peter-G.-M.-Lavelle/e/B00DW5G56I. I have also been making small revisions to the first two books and will republish them shortly as well. Many thanks to those who bought these and I hope you will enjoy the third book.

I would love to hear your comments or posted reviews on Amazon.

The Biggest Tool

A couple of weeks ago an announcement was made by a consortium of scientists from around the world about the discovery of gravity waves.

“Big deal,” I hear you say while trying valiantly to stifle a yawn.

Well its a big deal about something very small caused by something very big.

The wave was just 0.000000000000000000001m high.

Gravity waves are minute ripples in space-time, the four dimensional fabric of the Universe in which all of nature and history is played out. They were predicted as by Einstein’s General Theory of Relativity in 1915 but took a century to actually detect.

To put things in perspective let’s say a big human is 2m tall and weighs 100kg.

The Earth is 12,000,000m in diameter and weighs  57,000,000,000,000,000,000,000,000kg.

The Sun is 1,392,000,000m in diameter and weighs 1,989,000,000,000,000,000,000,000,000,000kg.

What created the gravity wave pulse was two black holes spiraling into each other under the attraction of their colossal gravity and merging. One weighed 36 times as much as the Sun and the other 29 times. In the process 3 times the mass of the Sun was converted in an instant into the gravity wave pulse. This would have been an awesome spectacle but you would not have wanted to be too close on account of the gravity sucking you in and the gamma rays spewing out from around the collision site.

All this happened 1.3 billion years ago and it took that long at the speed of light to get here. At that time all the land on Earth was concentrated in one big continent called Rodinia. The sea was full of single celled organisms. There would be no multicellular life for another 700 million years. Rodinia would have been completely devoid of even a speck of anything alive.

The gravity wave was detected by what could be described as the biggest tool ever built. There are two sets of L-shaped tubes 4 kilometres long with lasers and mirrors that do the measuring and they are located on opposite sides of the U.S. A third site is to be built in India to add more resolving power to the setup.

For me one point of interest was that the University of Glasgow was involved in the consortium. They were trying to measure gravity waves there in 1970 when I started studying Physics (or as it was rather grandly called, Natural Philosophy). It only seems like 1.3 billion years ago.

From Luxembourg to the asteroids

An odd duo of concepts in the same sentence caught my attention a couple of days ago.

The small country of Luxembourg (sandwiched between France, Belgium and Germany) has announced it intends to partner with just about anyone in the fledgling field of asteroid mining.

Now you can be forgiven if you are really ancient for remembering Luxembourg as nothing more than a radio station people in the UK used to listen to before BBC Radio 1 to BBC Radio 1,000,000 came along.

Delving a little deeper we find Luxembourg entered history under my old mates the Romans. What did the Romans ever do for them? Well, built some nice baths for a start.

After much to-ing and fro-ing it somehow emerged from the Middle Ages as a small and independent Grand Duchy. Now isn’t that a splendid title?

The Nazis wiped it from the map for a few years in World War 2. Now its greatest claim to fame is being home to various European Union organisations and who knows if that’s going to last?  I hope it does.

On a personal note I spent one day in Luxembourg on business in about 1978 so I feel a deep spiritual connection there.

And now the Luxembourgers want to mine the asteroids.

Well good on them! We are running out of precious minerals needed in all kinds of technologies. These being heavy metals mostly sunk down onto the molten core of the Earth over four billion years ago and are beyond our reach. It’s only the tiniest fraction in the top few kilometres of the crust we can ever mine. On the millions of asteroids they are much closer to the surface. Over the next fifty years the cost of utilising these resources will drop while the dwindling amounts left on earth will make the price rise. There’s also lots of ice out there that could make hydrogen for fuel and oxygen as well. There are a couple of American companies already making plans to get out there and do it with robotic spacecraft.

Of course the venture is highly speculative but full marks to Luxembourg for its long-sighted vision.

Mowing down the enemy – arms race

My adversaries the Bull Ants (Myrmecia) certainly have an advantage that is enviable. As well as being ridiculously strong for their size they have six legs.

Bullant_apr07

Now I don’t really need six legs. That would make me into some kind of octo-centaur and I suspect I would spend a lot of time tripping over my own feet. Just controlling two is as much multi-tasking as I can usually handle. But on the other hand six limbs would be ok if the additional pair came as arms.

This flash of inspiration came to me last weekend when I was scrambling over boulders at the top of Hanging Rock. Four arms (and still the two legs if you please) would have been very handy in some of the awkward spots.

Think of the boon to society if we all had four arms. The glove industry would double overnight and hopefully the deodorant industry would not be too far behind. The extra rings and nail polish required could bring whole economies out of recession.

Imagine what jugglers could achieve once they had mastered the hand-eye coordination! On the other hand we might see a lot more drab 0-0 draws at football as goalkeepers dominated. Boxing might have to invent new rules. Doubles at tennis would take on a whole new meaning.

All silly ideas but pretty armless.

Please feel free to add any equally daft proposals.

Mowing down the Enemy – Mercenaries

I swaggered across the battlefield gloating in the thrill of victory.

They might come again but I would be ready for them. I had cut them down to within an inch of their lives (or a couple of centimeters if you are metrically inclined).

Alas, what a fool! My guard had dropped. They had mercenaries lying in ambush ready to strike back when I least expected it.

As I approached the sacred fruit tree with a view to netting it and warding off aerial attacks (birds, but it could be worse) they struck a low blow such as their kind is capable of. The first wound was to the ankle. Then the thigh. How fast these mercenaries can move! As I brushed off the first wave of attackers more swarmed around and one struck at my hand.  I knew it was time to retreat and lick my wounds (or perhaps seek a more hygienic treatment).

These warriors were big, fast and fearsome. Their weaponry delivered a very painful wound.

You don’t want to mess with Bull Ants (Myrmecia) if you can avoid it.

Mowing down the enemy – Special Forces

I swaggered across the battlefield gloating in the thrill of victory.

They might come again but I would be ready for them. I had cut them down to within an inch of their lives (or a couple of centimeters if you are metrically inclined).

These warriors were big, black and fearsome. Their weaponry delivered a very painful sting.

You don’t want to mess with Bull Ants (Myrmecia) if you can avoid it.

Inspiration from Nature

If ever you’re feeling down (and who doesn’t from time to time) there is no better cure I know of than getting out in Mother Nature, Gaia or whatever you care to call it. It is a great way to recharge the mental batteries.

At the weekend I visited Wilsons Promontory National Park which is 500 sq. km. of untouched Australian mountainous wilderness sticking out into the Southern Ocean. The weather was warm and sunny but not too warm for long walks as it will get in summer.

The place has a pristine, primordial feel about it. If we humans had never come along with our cars and campsites it would have been even more so but thankfully development is kept minimal there.

The wildlife is abundant but mostly keeps out of the way during the day.

If you get the chance to visit this part of Australia and like the fresh air it is one of the many splendours on offer.
