11 Movie Mistakes Only Smug Nerds Would Ever Notice

2. Jurassic Park Has Magical Electricity And Computers

Another set of errors found in Jurassic Park by science nerds, and computer experts who don't take any time off from their jobs, even when watching a movie - admittedly, that's probably quite difficult when you're an academically-brained person confronted by a movie that basically makes up all of its science. Anyway, in the oddly comical scene in which Tim is shot across the sky by the newly-reactivated electric fence, there are two fairly sizable scientific errors, which would be bread and butter for anyone with a little electronics training.

Firstly, Dr Grant throws a stick at the fence to see if it is active, despite the fact that wood is an insulator, and is thus incapable of conducting electricity. That he takes the lack of response as enough evidence to grip the fence to double-check is a sorry indictment of his education. And then, Timmy is electrocuted, despite the fact that the simplest laws of electricity state that you cannot be electrocuted if no part of you is touching the ground.

Additionally, the real result of that much electricity running through Tim would have been an inability to loosen his grip as the charge turned his body into part of the live circuit, rather than him supermanning off away from the fence. In further electronics fails, Ray Arnold manages to hack into the park's security system without once following the proper procedures. Instead of entering superuser mode to access the sensitive system (by starting his command prompts with a "#") he uses normal user mode (indicated by the prompts starting with ">",) which wouldn't have given him access. His computer is clearly broken anyway, since none of his spoken commands correlate to the typed commands that appear on the screen.
