Re: What do physicists use?
I majored in Physics and loved Fortran. After working in accounting software for 35 years, I found that the best language for doing accounting is ... COBOL. Slow to code, runs okay, but when it absolutely positively has to work, or you have to be able to find the bug in a reasonable time, then there's nothing better. I've used or learned most everything else, from Assembler to C to Java etc. but COBOL is still the bee's knees when it comes to handling money. The economics of it makes sense: The financial industry just absolutely positively can not screw up their internal transactions. Unlike code like *cough* Windows *cough* which after running a really really long time (we're up to a week and half on the average now!) starts to corrupt internally.
'Nuff said. Mine's the raincoat made from a garbage bag.
