The natural world doesn't care about eloquence or debating skills. Something is either true, or it isn't. I always very much liked that about physics and various other real world skills. You can't trick your way around nature at all. This is also what I always really liked about computer programming: you can't expect the computer to take the blame for your errors, it's always you when things don't work the way you intended. This can get pretty touch, but the machine is patient, it will point out the error of your ways until you fix it, you can't convince it, you can not reason with it, you can only persist in your search for what is wrong. I love that aspect of the digital world.
