I was very sad to recently read of the death a few months ago of former IOP Deputy Chief Executive Rachel Youngman. We had lots of lovely chats and she will be very much missed.

The Lycurgus Cup is a 4th-century Roman glass cage cup made of a dichroic glass, which shows a different colour depending on whether or not light is passing through it: red when lit from behind and green when lit from in front.

The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behaviour of silver sulphide. Faraday noticed that the resistance of silver sulphide decreased dramatically as temperature increased.

The solution is a straight line from you to the reflected fire. Then reflect that part under the river back to the actual fire. It is really interesting to see how the Ss try to solve it.

In case you haven't seen it before, below is a nice puzzle I have set for classes in the past. There is a fire and you have a bucket which needs to be filled once from the river and one bucket will put out the fire. What is the minimum distance to do this?
