The Magnus effect in action, destroying the world, an astrophysicist camps out in Manchester and more
By Hamish Johnston and Michael Banks
This week’s Red Folder opens with a fantastic video (above) from the folks at Veritasium. It involves dropping a spinning basketball from the top of a very tall dam in Tasmania and watching as the ball accelerates away from the face of the dam before bouncing across the surface of the water below. In comparison, a non-spinning ball simply falls straight down. This happens because of the Magnus effect, which has also been used to create flying machines and sail-free wind-powered boats. The effect also plays an important role in ball sports such as tennis and is explained in much more detail in our article “The physics of football”.

The Institute of Physics (IOP), which publishes Physics World, launched its first-ever fundraising campaign at a dinner at the Institute’s headquarters in London last night. The aim of the campaign, called Opportunity Physics, is to raise £10m over five years to let the Institute “significantly scale up” its work over the coming decades. The evening was hosted by Manchester University particle physicist Brian Cox, who is on the fundraising campaign’s board and is a familiar face as presenter of TV shows such as the BBC’s Wonders of the Solar System.
The Institute says it has identified a number of existing IOP projects that can be enhanced if further funding were available. Those projects are all centred on inspiring young people into physics, showing them what careers physics can lead to, helping physicists to flourish – whether they work in teaching, research or industry – and underlining how physics is central to a healthy, technology-led economy. With 52,000 members, the Institute already does a lot of good work, but it believes it can do even more with additional cash.
