cold fjord writes: Steven Hawking, 150 fellows of the Royal Society (three Nobel laureates among them), and the Astronomer Royal, are warning that exit from the EU by the UK could be a disaster for science in the UK. An immediate issue would be restrictions on travel and how that would result in scientists from around the EU no longer coming to the UK to work. That would make the UK less competitive for new talent. It would also mean that scientists in the EU with grant money would be less likely to bring their research and grant money to the UK to perform their work. Switzerland is listed as an example of the resulting harm. The scientists make the point that freedom of travel for scientists is as important for science as free trade is for economies.
