Penzias, Wilson and some noise

The universe, Part 5
< From the beginning to atoms | Series index | No later items >

Penzias and Wilson discovered an unknown microwave signal that turned out to be evidence for the origin of the universe. The story involves inconvenient pigeon droppings and more than a little serendipity. It ends with a Nobel Prize for physics and fame.

The Holmdel Horn Antenna
In part 4 of the series we saw how the cosmic microwave background radiation (CMBR) provides the earliest visible image of structure in the universe.

This time we're going to follow the curious story of its accidental detection by Penzias and Wilson.

The Holmdel microwave antenna in the image is at Bell Labs in New Jersey and was built in 1959 for early radio experiments with the Echo satellites (reflective balloons in earth orbit).

The horn antenna was being used by Arno Penzias and Bob Wilson in 1964. They were building sensitive, low noise, microwave radio receivers for use with the Echo satellites and had a serious problem with unexplained radio noise. They ruled out several possible causes, including a build-up of pigeon droppings in the horn, but nothing they could think of seemed to reduce the frustrating noise. Eventually they concluded it was not noise, but a genuine signal from an unknown source.

The noise explained - Another physicist, Robert Dicke had been searching for a signal just like the one that had caused Arno and Penzias so much trouble. Dicke had failed in his search but he heard about Penzias and Wilson's results and recognised it as relic light from the early universe, the elusive CMBR! The Penzias and Wilson paper and another by Dicke and three others were published together in July 1965. There's a lot more about this story in the book 'Genesis of the Big Bang' by Ralph A Alpher and Robert Herman who remembered the events well.

This is an interesting example of the way science progresses. Dicke, like George Gamow before him, had predicted the CMBR based on cosmological theory. Now that it had been found, the credibility of the theory was greatly strengthened.

Dicke was soon able to observe the CMBR himself, and later the COBE satellite would observe it in much greater detail, finding small irregularities in temperature. These too had been theoretically predicted.

When experimental results bear out theoretical predictions like this, scientists can be confident the theory is on track and more likely to be reliable.

WMAP, Planck and other instruments have refined the detail still further and strongly support the current Standard Model of Cosmology known as the Lambda-CDM Model..

Penzias and Wilson were awarded the Nobel Prize for physics in 1978 for their discovery.

Ecotricity - greener, greener, green

Ecotricity builds wind and solar generating systems. They also supply green energy to commercial and domestic customers in the UK. Starting from small beginnings they have made a significant impact in the market and continue to grow rapidly in capacity and popularity.

Turbine blades transported by road
Ecotricity was started by Dale Vince who built a small windmill generator from reclaimed components for his own use.

Friends asked him to build similar generators and eventually he made a much larger one for a local farmer.

He then wanted to build something even larger to connect to the grid, but hit all kinds of difficulties and additional costs imposed by the larger companies and distributors.

Through persistent effort he managed to negotiate a deal and since then Ecotricity, the world's first green electricity company, has built many more large wind turbines and wind farms.

Innovation - Dale has had many interesting and innovative business ideas and has never been willing to take 'no' for an answer. He raises extra finance by issuing bonds, his company also sells wind and solar generated power to end users and offers (at slightly higher cost) a 100% renewable deal.

They have a policy of not having shareholders; instead, profits are ploughed back into building additional generating capacity. The company encourages new customers to sign up so as to use their power bills wisely, in other words to help build additional capacity. Their customer service is exceptionally good, polite and helpful.

More recently Ecotricity has also developed a green gas plant, generating methane by biodigestion of waste. Dale has built record breaking electric vehicles, both a motorcycle and a high performance car that recently set a new world land speed record for electric vehicles.

Caring for the planet - Surely we have a duty to care for the planet on which we live? Dale Vince is certainly doing his part to reduce environmental damage. If you live in the UK you could help simply by changing your electricity and/or gas supplier to Ecotricity.

In other parts of the world you may be able to help in other ways. We can all do our part by reducing our use of energy, by walking or cycling instead of driving, by flying less often, by taking the train, insulating our homes, turning down the thermostat, showering more quickly - the list is long.

But many small actions by large numbers of people add up to a significant difference.

Making the switch - You can switch to Ecotricity online (if you use this link I'll get a partner contribution from the company). If you prefer to speak to them by phone call 08000 302 302 and quote 'SCI1' and I'll still receive the contribution.

Questions:

  • Have you heard of Ecotricity before?
  • Are you doing all you can to reduce your household and business energy use?
  • Are you using green sources of energy where available?

Don't miss the dawn

Words from a few years ago now seem to be relevant. These words may be for you, if they are you will know because they will resonate for you. They are words from the Light about the Light. These are words about a journey, about an announcement, and about the glory of the coming day.

Like a new day dawning
Here's something I was given and wrote down a few years ago, but I sense that now is the right time to share it.

If this is for you I'm sure you'll recognise it.

There is a new light shining in the eyes of everyone who is looking for it. It's a new dawn, a new day, a new light yet it's the oldest light in existence, older even than the universe itself. It's the light of Christ shining into a dark world.

But I tell you, unless your eyes are open you will not see this light clearly. Unless you are looking for it you will see dimly and overlook the truth. Here is what the Lord says.

'A new thing is coming but not all will walk through it with me. The light of revival is already glimmering like a new dawn in the hearts of those who've been praying for it and searching for it and hoping for it.'

'Get up now while it's still dark, prepare yourself for a journey, light a lamp so you can see to make a meal and tidy up your affairs, set out the clothes you will wear on the road, get dressed, wash your face, and put on a warm coat. Then put out your lamp, step outside and close the door and begin walking to the place where the sky is bright and the sun is about to rise. Listen, the birds are already singing for the dawn.'

'Many of your neighbours are asleep in bed, they will awake to the full light of day. But you will have experienced the dawning and will be ready to call out as you journey, "Wake up, rise up, come outside for the Light is shining and the darkness is gone. Come out, come and feel the radiance and the warmth, come outside and see the glory of the day."'

'The day is short and there is far to travel.'


Questions:

  • Does this speak to your heart? If so, what is the Spirit saying to you?
  • Can you share this with others who might need to see it?
  • You may have more to add, if so would you be willing to make a comment?

Robots dancing

Bruno's dancing robots are beautiful to watch, but what they do and the feelings they convey come through the robots from Bruno. They have no life or emotion of their own, but they almost convince us that they have. Does this tell us anything about our relationship with our Creator?

Robots dancing on stage
I simply had to share a recent TED Talk with you.

Bruno Maisonnier's demonstration of robot choreography and dance is really quite beautiful. He titles it 'Dance, tiny robots!'

Of course, the beauty and emotive content in the dance all comes from Bruno's heart and mind and is just expressed through the robots much as a musician expresses emotion through an instrument or a painter through brushstrokes. But it is exquisite to watch.

The robots don't have emotions, Bruno does. But because the robots dance, the feelings aroused in us, the audience, are strangely transferred from the man to the mechanical. This isn't surprising, when we are moved by music or art we may not even know who produced it.

But when the medium is a group of mechanisms that make human-like movements we can almost believe they are alive and have feelings.

What is it that is expressed in us? Is it the presence of the Creator in the created? We are not robots, but is he far beyond us in the same way Bruno is far beyond those dancing robots? If robots can move in ways that hint at their programmer's emotions, what do humans hint at about the Most High?




Questions:

  • Did you enjoy the performance?
  • How long do you suppose it took Bruno Maisonnier to program the dance?
  • What does this say to you about creators and the things they create?

Simple church with children

Donna lives in Nottingham and is meeting children on the streets and simply involving them in church life. There is a pattern to what she is doing, a simple process at work. Watch the video and see for yourself. This is exciting. This is church at its simplest and best. This is Jesus doing his stuff.


My friend Donna is doing simple, organic church with children from her area.

You can watch a video of her with three of them and hear what she has to say about it.

Watch below or on the Simple Stories website. Either way be sure to visit the Simple Stories homepage afterwards, there is much more there to see and read.

Come back here after you've seen the video and let's think about this for a moment. There's a very simple process at work here, can you spot it? It has nothing to do with taking children to church. It has everything to do with being church. And it has a lot to do with making disciples just as Jesus told us to do (Matthew 28:18-20).

The Pattern - Here's an outline of the simple process Donna is following.
  1. Donna has met children on the street near her home.
  2. She has told them the good news that Jesus loves them.
  3. She is meeting with them regularly and showing them that they can pray for one another and have a lot of fun together and read the Bible together.
  4. She is getting to know the parents as well.
  5. She's encouraging the children to pray for their friends and to start their own, new simple churches with them.
These children are doing much more than most of us adults ever do. They are planting churches!


Papa, bless Donna and the children in Nottingham as well as their friends and families. Keep them close to you, Jesus. Help them walk with you every day and listen to what you are saying to them.

Oh, and teach us to be obedient just like they are!

Go! Go! Donna!

Thank you, Jesus. HalleluYah!


Questions:

  • Do you see how easy this is? Anyone could do it!
  • Can you see how you could use the same approach with the people you meet in daily life?
  • What is stopping you making a start today?

On the Market Square

We offer 'Free Hugs' in St Neots Market Square and get a variety of responses from the local people. Along with those who disregard us and won't engage there are some who want a hug and others who want a conversation as well. One conversation went considerably deeper. Hearts were touched.

Cold day on the Market Square
Yesterday I met Mark and then Tendai for coffee and prayer at Cornerstone. We were joined briefly by Steve from New Street Baptist Church before heading out to the Market Square to offer 'Free Hugs'.

I quickly discovered that there are two kinds of people on the streets. There are those that behave as if you are completely invisible. And there are others who smile, engage in a brief conversation (or even a lengthy one) and sometimes accept the offer of a hug.

Some people want to know why we are offering hugs, or what the catch is. Some are not especially interested in those questions. Some accept a brief prayer or a blessing as well.

Relatively few younger people are interested in hugs, many seem quite embarrassed by the idea (perhaps because we are older than they are or their mates are watching). But there was one notable exception.

A guy was approaching on a skateboard and I waved my 'Free Hugs' sign and smiled at him. He jumped off his skateboard, beamed at me and said, 'Why not?' I had perhaps the warmest hug I got all day and he enthusiastically told me I'd made his day. 'More people should do this sort of thing', he said, jumping back on his board and heading off to the local skate park.

Good conversation - Towards the end of our time in the Market Square I had a long and lovely conversation with a local trader. She told me some things about her life, how she sometimes knows about things before they happen, and how she'd once been told by a pastor that she was cursed. Why do people say unkind things like that?

As we were about to leave I asked her if I could pray for her and bless her. She was OK with that and accepted a hug as well. I thought I detected tears in her eyes afterwards, unless it was just the bitter wind.

But it's not just the wind that can bring tears to our eyes. Bitter events in our lives can bring tears within our hearts as well. They blur our spiritual vision and prevent us from seeing what is right before us. We all need to know we are loved by a Father in heaven who truly cares about us.

Giving people a hug is always a good thing. But Papa can give us all the inner, spiritual hugs that we so desperately need, even though we sometimes don't know it.

Questions:

  • Are you connecting with people in the area where you live?
  • If so, how? Tell us about it, leave a comment.
  • Take a look at Chris Duffet's website, are there ideas here you could use?
  • Can you think of similar ideas for engaging people? Leave a comment to share them.
