Dark Matter

Not really understanding but knowing it’s important!

I recently read a glowing review of the latest book by Sir Roger Penrose, the eminent mathematical physicist, called The Road To Reality. Having previously read his book The Emperors’ New Mind and just understanding it, I thought

Roger Penrose

his next one would be a welcome companion for long winter evenings.  Wrong!

I managed to the bottom of the third page of the preface before “According to the mathematician’s “equivalence class” notion …..” had me grasping for meaning.  Well over a 1,000 pages of content was destined to gather dust on the bookshelf.

But wrong again!

The idea of matter out there in the universe that is essential to the universe as we know it but is unseen has been sufficiently fascinating for the popular media to refer to it from time to time.  Most people are familiar with the term even if like me don’t really have a clue as to what dark matter is all about.

So a recent press release in a popular English newspaper suggesting that dark matter has been ‘discovered’, if discover is the appropriate term, had me reaching out for Penrose’s book again.  There under the chapter headed Speculative theories of the early universe was, on page 773, a few sentences that almost made sense.  Let me quote them:

For many years, it had become clear that the dynamics of stars within galaxies does not make sense, according to standard theory unless there is a good deal of more material in the neighbourhood of the galaxy than is directly seen in stars.  A similar comment applies to the dynamics of individual galaxies within clusters.  Overall, there seems to be about 10 times more matter than is perceived in ordinary baryonic form.  This is the mysterious dark matter whose actual nature is still not agreed upon by astronomers, and which may even be of some material different from any that is definitely known to particle physicists – though there is much speculation about this at the present time.

A hero

Another example of the power of social media.

I subscribe to Naked Capitalism, as much for the Antidote du Jour, as for the fine economic commentaries.  In my inbox of the 16th December was this wonderful antidote.  A quick Google search shows that these pictures are spreading like wildfire around the world’s email servers.  Not without reason.

Maybe these pictures resonate in all of us when we long for some simpler way of life …..

This Ranger is assigned to prevent poaching around the wildlife refuge area of Lanseria, South Africa. The way these animals interact with him is absolutely stunning! The lions seem to know he’s there to protect them. His charm works with hyenas and cougars too. Hyenas are usually vicious. Check out the pictures taken in the river – amazing because lions hate water.

As they say, don’t try this at home!

Remarkable people: Dame Shirley Bassey

The wonderful, irrepressible DSB – Dame Shirley Bassey

This wonderful lady was born in 1937 and, thus, next January 8th she turns 73.  So for this author, born in 1944, DSB has been in the background of my life for ever, and for millions of others.  There is so much written about her that the only purpose of this Post is try and bring her to the attention to those that may not know of her so well.

I only have to think of the soundtrack to the film Goldfinger to instantly hear Shirley Bassey’s voice loud and clear in my mind.  Unforgettable, stunning, thrilling and still capable of raising the hairs on my skin now over 40 years since the track was recorded.  Just listen to this voice:

Greg Craven and his message

How to approach the global warming dilemma.

Yesterday, a Post was published a Post about Greg Craven.  It made the point that social media was becoming a very real force in influencing opinions and how that threatened traditional politics.  Here’s an extract:

I was doing some research for an earlier Post about Copenhagen and came across a YouTube video created by Greg.  More details and links later after making a more fundamental point.

This video of Greg’s has had 2,704,000 viewings! The information on that YouTube ‘page’ has had over 7,500,000 viewings. Greg has now written a book and so on, and so on.

Now I want to return to the core subject of how we deal with very complex issues that have the power to decimate humanity, e.g. global warming.

The fact is that the majority of people who think about such issues as global warming don’t have the skills and knowledge to determine what to do for the best.  It comes down to determining risks, which was the theme of an earlier Post acknowledging the work of Peter L Bernstein.

That’s also the theme of Greg Craven’s video on YouTube.  It’s a noble effort by a concerned citizen of Planet Earth.  Watch it.

Copenhagen – the unspoken issue

It’s getting crowded down here!

For those readers who are not regular BBC television viewers, the Beeb has for many years run an excellent factual/science & nature series under the name of Horizon.  Just recently there was a programme with the title of How Many People Can Live on Planet Earth?

Sir David Attenborough

It was presented by that familiar face on the BBC in terms of the natural world, Sir David Attenborough.  It was an appropriate and worthy person to present the information.

But before getting into some of the details underpinning the programme, there seems to been an enormous and unspoken omission at Copenhagen – why no debate about global population trends?

Luckily the media noticed the rather obvious exclusion.  Here’s the UK Daily Telegraph newspaper (online version) of the 8th December, 2009. An extract:

Population growth is the one issue accused of causing driving climate change that no one at the Copenhagen climate summit dares to talk about.

The argument is that more people consume more resources, therefore producing more greenhouse gases that cause global warming.

The global population is currently at 6 billion and could rise to 11 billion by 2050 if fertility rates continue, not only threatening the climate, but food shortages and conflict as well.

Organisations like the Optimum Population Trust, that is backed by Sir Jonathan Porritt, Dame Jane Goodall and Sir David Attenborough, advocate birth control as a way of slowing climate change.

As Sir David has said: “I’ve never seen a problem that wouldn’t be easier to solve with fewer people, or harder, and ultimately impossible, with more.”

A study by the London School of Economics found contraception is almost five times cheaper as a means of preventing climate change than conventional green solutions such as investing in green technology.

Greg Craven and the power of social media

There’s a new power on the streets and it may make politicians feel very uncomfortable!

The Rt Hon Gordon Brown

Like me, you probably haven’t heard of Greg Craven.  I hadn’t until about 24 hours before starting to write this Post (that would be Friday afternoon, Mountain Time, on the 11th December).

I was doing some research for an earlier Post about Copenhagen and came across a YouTube video created by Greg.  More details and links later after making a more fundamental point.

This video of Greg’s has had 2,704,000 viewings! The information on that YouTube ‘page’ has had over 7,500,000 viewings. Greg has now written a book and so on, and so on.

In other words, the personal message that Greg is conveying has reached an unbelievable number of people.  That would have been impossible without the power and reach of modern social media software systems: YouTube, Facebook, Linked-In, Twitter, MySpace, Digg, at al.

In the past, information has flowed outwards in a much more ‘top down’ way.  Hierarchical, as it is called.   That has suited those that wish, in some way, to control the message.  While individuals would always chatter and gossip with their peers, there was a finite limit to that before “Send reinforcements, we are going to advance” morphed into “Send three and fourpence, we are going to a dance”!

The example of Greg Craven shows only too well how information can now flow.  Out of anyone’s control, spreading virally.

Having made my point, I want to return to the subject matter that Greg is championing – but will include that in a separate Post.

Politicians!  Be very careful what you say.  We are all listening now, in one way or another, and ready to pounce if we don’t trust your words!

Copenhagen – that’s clear then.

Will we ever know the truth, the whole truth, and nothing but the truth?

It’s a week since the start of The United Nations Climate Change Conference – Copenhagen, 2009 and it’s clearly been a media success if nothing else.

My instinct has, for many years, been the assumption that mankind behaves in many ways that harm our environment and that, ultimately, harming the very planet upon which our survival depends could happen.  Stupid, yes!  But in line with some of the more strange behaviours of homo sapiens.

But like millions of people, I do not have either the scientific background or the time available to test the statements made by so many governments and other ‘wise’ bodies as to whether the science of climate change, global warming or whatever, is real and irrefutable.  One thinks that would be relatively easy to do and that after all the years and millions of dollars spent on climate research, the proof would be there.  Cause and effect were perfectly understood.

There are graveyards, and graveyards!

The almost surreal area where aircraft are ‘laid to rest’.

The Mojave Desert is one of the places in the world where aircraft, both military and civil, are placed when they are at the end of their life, whatever that means.

Anyway, came across some nice material and wanted to share it.

In an earlier copy of Mental Floss Magazine (seriously) there’s a very good article about this area.  Fabulous pictures, by the way. (Both pics in this Post are from that article.)

Next this is a YouTube video using Google Earth in flyover mode:

Finally, a reminder that it’s not all about dead aircraft.  The Mojave Air & Space Port is also the site of the privately backed SpaceShip enterprise.

All in all, not your average place.

Aerial photography

Some chilling reminders of the reality of war!

Britain has a National Collection of Aerial Photography.  It is held within the offices of the Royal Commission on the Ancient and Historical Monuments of Scotland – perfectly logical!

A summary of the different collections is listed here, many of them wartime photographs that bring a multitude of emotions to the surface: incredible bravery of the pilots; photographic standards of 70 years ago, man’s inhumanity to man; and so on.

I pondered a bit about writing this Post because, well ….. well…, see what you make of it!

Author's Mum

Being born in England in the early part of November, 1944, World War 2 still resonates within me.

Early home in an industrial part of West London meant that my mother and father had a ring-side view of the German V1 and V2 rockets that were being visited on London at that time.

My mother, 90, still recounts her enormous sense of relief when VE Day was announced (May 8th, 1945) because she then thought that her son’s future life was more or less assured.

So back to these aerial photographs held in those collections.

Here’s a picture of the visitation of war on the beautiful French town of Caen.

Linger a while and look at the damage, mostly to private homes.  The photograph was taken just slightly more than a month before I was born.

So where’s this Post leading to….?

Poetry and dogs

Thanks to Daniel Caride for pointing us to this poem from an unknown author.

It is called Inner Peace.

If you can start the day without caffeine,

If you can always be cheerful, ignoring aches and pains,

If you can resist complaining and boring people with your troubles,

If you can eat the same food every day and be grateful for it,

If you can understand when your loved ones are too busy to give you any time,

If you can take criticism and blame without resentment,

If you can conquer tension without medical help,

If you can relax without liquor,

If you can sleep without the aid of drugs,

You are probably the family dog!

Pharaoh, 3 months, asleep oblivious to the world!

Yes, we certainly have much to learn from dogs!
