Sanctuary bays

Sometimes, I’m not sure about where I am on a topic, a topic for example such as Mallows Bay Sanctuary:

From what I can gather, the PTB decided that this was to be a sanctuary, so they hauled a whole lot of old ships there and sank them.  Now no one can go there.

My ambivalence is that, being a closet semi-greenie, I love wilderness and nature being allowed to freely do what it does best.  However, this seems quite contrived and when Man, especially Left Man, starts interfering, w-e-e-e-l-l-l-l …

Earth quiz

1. What makes thunder?

If you thought, “Lightning!” then hats off to you. But I had a more illuminating answer in mind. The air around a lightning bolt is superheated to about five times the temperature of the sun. This sudden heating causes the air to expand faster than the speed of sound, which compresses the air and forms a shock wave; we hear it as thunder.

NASA

So, what have we actually got on our hands here?

A British teenager has contacted scientists at Nasa to point out an error in a set of their own data. A-level student Miles Soloman found that radiation sensors on the International Space Station (ISS) were recording false data.

The 17-year-old from Tapton school in Sheffield said it was “pretty cool” to email the space agency. The correction was said to be “appreciated” by Nasa, which invited him to help analyse the problem.

“What we got given was a lot of spreadsheets, which is a lot more interesting than it sounds,” Miles told BBC Radio 4’s World at One programme.

I’d refer back to two things:

1. In Tenerife, on that KLM plane, the young Flight Engineer noticed the Captain was wrong in his judgement of the situation prior to takeoff. That Captain had almost flown his full time quota for the day, he was a decorated and feted man, featured in flight magazines, he was a KLM hero.… More here ...

Two topics

1. All power to NZ, I say:

“We were joking with them that it was a bit like being young again at an American holiday camp,” said Jenny Nuku, treasurer of the Maori community center, called Te Puea Marae. “They all were laughing.”

While the alternative accommodation made for a unique cultural experience, it illustrates how New Zealand’s tourism boom is stretching infrastructure to breaking point. With 3.5 million short-term arrivals last year — 480,000 more than had been projected only two years earlier — a lack of capacity may end up harming the nation’s biggest foreign exchange earner.

Tell you what – I’d prefer that to a bleedin’ all-the-same hotel.

2.  This man running a mobile laundry service for the homeless:

Powers started the program, which he dubbed Loads of Love, last year after seeing a YouTube video about Orange Sky Laundry. According to its website, the Australian nonprofit was founded in 2014 as “the world’s first free mobile laundry service for the homeless.”

Who would do such a thing?  Ah:

A devout Christian, he wanted to shift from discussing the teachings of the church to living them out by helping others.
