Henry Moseley

Talented British physicist Henry Moseley, killed at Gallipoli- as with Alan Blumlein, what might have been.... Programme on BBC World Service this evening at 1832 and 2332 and (insomniacs) 0432 (all GMT, add an hour for BST!);

As a physics undergraduate and then a doctoral student I remember that one of Moseley's original graphs of the relationship between atomic number and X-ray frequency was displayed on the main staircase of the building I worked in. The department was rightly very proud of it. One of the things which struck me about it was how large it was - somewhere between A1 and A0 as I recall !

I'm just about old enough to remember physical graph paper being used 'in anger' to interpret experimental results. Our stores kept quite a range. As well as the usual linear stuff (which we had printed from our own plates, to save money) you could also get various types of Log-Lin and Log-Log if you needed to determine power-law relations between data sets. If your data had very low error bars then bigger bits of paper could actually give you higher precision !

Yep - I remember when such graph paper was held in the office when I started my life in television...

I do still have various pads of graph paper of various scales which I use from time to time.

There's little substitute for manual graph plotting - interacting directly with the data and seeing the plot evolve means that spurious results can be picked up more quickly.

The lab where I worked used to keep a good selection of loglog, and loglin in various numbers of decades. Nice looking stuff.

It was expensive stuff, latterly I used to cheat by using the full sized Chartwell? samples book and a photocopier.

These days, of course, you can print your own without the random distortions that your photocopier might have introduced!

For example:
