This Is Why Under-Inflated Footballs Could Have Given Tom Brady An Advantage

| Fri Jan. 23, 2015 6:20 PM EST

To those of us for whom the nuances of professional football tactics are a bit of a mystery, there was one question looming over New England Patriots quarterback Tom Brady's surreal Ballghazi press conference yesterday that went unanswered: What's so great, in theory, about a deflated football? Seems like, if anything, an under-inflated ball would be less aerodynamic?

Turns out, the potential benefit is all about grippiness. From Fox Sports:

John Eric Goff, professor of physics at Lynchburg College in Virginia and author of “Gold Medal Physics: The Science of Sports,” told FoxNews.com that the league-mandated PSI range is ideal for playing football. “If, however, there’s rain or snow or something else happening, that would make the ball a bit slicker, so having a bit less pressure in the ball makes it easier to squeeze and the grip improves,” he added.

Interesting!

One Perfect Tweet Sums Up Why Climate Denial in Congress Is So Dangerous

| Thu Jan. 22, 2015 4:13 PM EST

Here's the good news: Yesterday the Senate voted overwhelmingly in favor of an amendment to the Keystone XL bill that says "climate change is real and not a hoax." Good work, ladies and gentlemen! Glad we got that on the record, only 25 years after scientists agreed on it.

Here's the bad news: Turns out the vote was just an excuse for James Inhofe (Okla.) to say, as he has many times before: Sure, climate change is real. The climate changes all the time. But humans aren't the cause.

His evidence for this dismissal of the mainstream scientific consensus? The bible.

Oy vey.

Now here's the really bad news: This same gentleman from Oklahoma recently became the chairman of the very Senate committee that oversees environmental policy. And two of his climate change-denying peers will chair other subcommittees that oversee vital climate science.

In case it isn't self-evident why these facts are so terrible, we have our lovely readers to sum it up:

Thanks, Sharon Dennis!
