## Conditional Admissions to grad programs--how common are they in the wild?

Grad programs--I've just heard (for the first time) that conditional admissions are A Thing. Would I have a snowball's chance with a good GRE score alone or will I have to take pre-req undergrad classes first? [more inside]

## How do I elegantly present tabular, statistical data online?

How do I elegantly present tabular, statistical data online and automatically?
I'd love some examples of beautifully presented tabular data online - something that works natively in a browser, ideally also on a tablet and mobile as well. Some interactivity (sorting, filtering) also OK but priority is usability and elegance like you'd find in printed statistical abstracts. Bonus points for open source web tools / frameworks that could help automate this from a database! [more inside]

## Help me keep my SmartyPants image shiny.

Considering the huge amount of oil/energy expended driving trucks full of food all over the country, would it make more sense to increase our train infrastructure (is that even possible?) to move more food? That's the question, but not why I've come to Metafilter. [more inside]

## Data on civilian casualties of war?

I am interested in seeing some comparative data on the civilian casualties of warfare, particularly in the 20th and 21st centuries. Are there any great analyses of this topic, perhaps on DVD, YouTube, or illustrated in books with graphs? (I have a hard time envisioning the magnitude of these things when they are presented only as bald numbers.) I started thinking about this topic after watching The Fog of War, which is a documentary about Robert McNamara. He presented some amazing comparative information about World War II and the Cold War. I would love to acquire a similar critical context for other conflicts, including the recent wars in Iraq and Afghanistan.
