That is actually untrue. The Daily Telegraph reported on 1 Feb that the time for the exam had been extended for ALL students. This was done supposedly to help female students but of course it can benefit male students too since they also may be helped by the extra time available. Never let the facts get in the way of a controversial journalistic statement though!

Hey did you know that Oxford Uni now gives female students extra time for their exams?
What do you all think?

Hi Mark,

It is a very cool experiment – I wish I had done it. Thank you for the picture. I can use it this semester while teaching about a particle-in-a-box in QT.

I think the “size” of the “atom” depend on the pixel size of the camera and its resolution abilities. By comparing the width of the “atom” to the width of the gap we get about 1/30. If the gap is 2 x 10E(-3)m as stated in the report then the atom is around 7 x 10E(-5)m or 70,000 nm, much bigger than I would have expected for a single atom. So even though the atom is “stationary” we do not know exactly where it is and no laws of QT have been broken.

☺

And yes, I know it has been done before .... It is more the fact it actually makes the news!!!
