Widgets not appearing on mobile device

I like how this site appears on mobile devices. It’s clean and neat, but I would really like to be able to see the sidebar widgets (or at least one of them) when viewing the site on a mobile device.

I don’t really want to incorporate my widget functionality into the page itself so it appears on a phone or tablet device.

Any help would be greatly appreciated.
