Knots have varying degrees of complexity — they can be twisted to become unrecognisable. To determine the complexity of a knot, mathematicians imagine them in a 4-dimensional space where they can manipulate the knots even more. Some mathematicians allow themselves to lop off loops or add extra ones to compare them with knots that look similarly complex, but they do have one rule; the knots are closed loops to prevent mathematicians from simply unraveling and retying them until they remake the knot in its original form.

Improving media literacy could boost trust towards the news, IMPRESS report suggests
The UK media is regulated by the likes of IPSO and Ofcom. The report by press regulator IMPRESS highlights the link between low levels of media literacy and trust in the news.

It suggests that improving media literacy is one way to stem the erosion of trust, and shows that audiences have an appetite for information on news processes. Stakeholders need to collaborate in order to rebuild trust in the news, and independent media is well placed to do this. Read full article here
