Collaborative Preferences for Learning Mathematics: A Scale Validation Study
Collaboration within mathematics has been established as being effective in providing students with crucial opportunities to develop critical thinking, effective communication, and teamwork skills. By engaging in group problem-solving and shared learning experiences, students may gain deeper insights into mathematical concepts and learn to approach challenges from multiple perspectives. However, there remains a need for a reliable instrument to capture students' preferences for collaboration. T…

Scale without conformal symmetry in hydrodynamics
Scale without conformal symmetry corresponds to an inhomogeneous conservation equation for the virial current sourced by the trace of the energy-momentum tensor. Fluids that are just scale-invariant differ qualitatively from their conformal counterparts, and generic dissipation effects relax the hydrodynamic response over sufficiently long time scales. Remarkably, this holds true already at the ideal order. Spontaneously broken scale symmetry does not, in general, add any new mode to the hydrod…

Content warning: heartening interviews with the over-60s getting arrested

“I’ve been a very law-abiding citizen and very respectful of authority all my life but I knew I had to do this and it was my duty to do this.”
- Deborah Hinton, 81
“The focus shouldn’t be on Palestine Action. The focus should be on what the government isn’t doing for the Palestinians in Gaza and the West Bank.”
- Father John McGowan, 75
“As a former officer in the British army, I am horrified that the government is misusing our armed forces to be complicit in the genocide rather than to end it.”
- Chris Romberg, 75
“Palestine Action’s methods sit very uneasily with me. It’s difficult to accept that vandalism is the only way to go. However, I feel we have to do something and I support their stand against genocide.”
- Richard Whitmore-Jones, 74
“The policeman said: ‘You’re a bit heavy.’ He had to call one of his friends over to help carry me. I thought that was a bit of a liberty.”
- Trevelyan Evans, 64
