Whats harder – brain surgery or rocket science?
Anna Waits, York • Rocket science, I’d imagine. Brain surgery is performed hundreds of times each day, worldwide, whereas only a few rockets go up into space each year. Daniel Morgan, Jupiter, FL, USA • Presumably, rockets are successfully built, launched and landed because the scientists actually do understand rocket science. The brains that go behind rocket science are rather more complex. Sheila Kirby, Esbjerg, Denmark • It depends on the aspect. The theory behind brain surgery is quite simple. That behind interplanetry rocketry complex. But the doing of brain surgery is far more demanding than building and firing rockets. Peter Brooke, By Kinmuck, Scotland • Definately brain surgery. We pretty much know everything we’re likely to about launching rockets into space – the problem is now largely one of quality control. Most of the brain’s higher functions though are still a mystery. Martin Porter, Glossop, UK • Rocket science is dead easy – it’s basically momentum conservation, which
