Schools switching to clip-on ties
Clip-on ties are replacing knotted school ties as schools worry about health and safety, says a survey of school uniform suppliers.
The Schoolwear Association says 10 schools a week in the UK are switching, because of fears of ties getting caught in equipment or strangling pupils.
There are also claims that clip-on ties can stop pupils from customising the size of the knots in their ties.
Uniforms are an “instrument of social levelling,” says the association.
The Schoolwear Association, the trade body for the school uniform industry, has been identifying this year’s trends.

The break of the curveball
This is actually pretty cool, especially for those of you that have actuallly seen a curveball. Be sure to check out the animation here.
In baseball, a curveball creates a physical effect and a perceptual puzzle. The physical effect (the curve) arises because the ball’s rotation leads to a deflection in the ball’s path. The perceptual puzzle arises because the deflection is actually gradual but is often perceived as an abrupt change in direction (the break). Our illusions suggest that the perceived “break” may be caused by the transition from the central visual system to the peripheral visual system. Like a curveball, the spinning disks in the illusions appear to abruptly change direction when an observer switches from foveal to peripheral viewing.
