Orion Through The Camera — But Which Type?

Orion Through The Camera — But Which Type?

Recently on Countryfile (BBC) we saw a presenter and a photographer together in the Pennines, the mountains that form the ‘backbone’ of England.  The photographer makes a living by taking spectacular scenes with a high-end camera and all different lenses, whereas the presenter was comparing what she took with her mobile. 

He was worried that in the public domain the best images would be lost in a massive cloud which includes a lot of inferior (though he didn’t specifically use the word) data.

This clicked with me, because of my experience of attempting astrophotography with what is known as a ‘bridge’ camera, somewhat between a compact and an SLR.

Fish and flowers inspire diving goggle material


says an article in Chemistry World. 

First, the fish.  Fish repel oil by trapping water within their scales to create a self-cleaning, oil-repellent coat.

And in the other corner, this little flower, Diphylleia grayi, – also known as the skeleton flower – which has the property that when rained on, its petals turn transparent, becoming white again on drying out.

Recently on Real Clear Science, Ross Pomeroy published an article Why Nothing Can Be Truly ‘Unnatural’, in which he denounces attempts to oppose homosexuality on scientific grounds.  However, after reading it, I am left with the feeling that he is not simply reporting science, but perhaps being a little bit like an old-fashioned nanny telling her charges what is or is not proper.  If so, he will be firing a shot in

Are ancient remedies any good?  In scholarly circles the middle of the 20th Century, they didn’t seem to think so.  For example:

‘Survey the mass of folly and credulity that makes up Anglo-Saxon leechdoms, it may be asked: “Is there any rational element here? Is the material based on anything that we may reasonably describe as experience?” The answer to both questions must be “Very little”.’ [1]
