Wood that's stronger than steel

1 Share

Researchers demonstrated a new process that makes wood stronger than steel. According to the University of Maryland mechanical engineers, their novel process could lead to a greener alternative to metal in automobiles, airplanes, or buildings. “This could be a competitor to steel or even titanium alloys, it is so strong and durable," says researcher Liangbing Hu. "It’s also comparable to carbon fiber, but much less expensive.” From the University of Maryland:

The team’s process begins by removing the wood’s lignin, the part of the wood that makes it both rigid and brown in color. Then it is compressed under mild heat, at about 150 F. This causes the cellulose fibers to become very tightly packed. Any defects like holes or knots are crushed together. The treatment process was extended a little further with a coat of paint.

The scientists found that the wood’s fibers are pressed together so tightly that they can form strong hydrogen bonds, like a crowd of people who can’t budge – who are also holding hands. The compression makes the wood five times thinner than its original size.

The team tested their new wood material and natural wood by shooting bullet-like projectiles at it. The projectile blew straight through the natural wood. The fully treated wood stopped the projectile partway through.

George Bush Was Bad

1 Comment
And I am mad that so many people have the memory of fruit flies. George Bush was really really bad. The Bush administration was really really bad. Lots of bad things happened. He said a few good things after 9/11 (he did! I always gave him credit for that) and then decided to go kill a bunch of Muslims just because he wanted to be a War Preznit. We tortured some folks. A million people died.

I have no doubt that the Trump era could end up being much much worse. But we aren't there yet. Not even close.

Listen To Me You Damn Kids

Bush was horrible. Horrible horrible horrible. Obama was also fucking horrible, but much better! The theater of Trump is more horrible than anything we could have imagined, but so far (Puerto Rico is big exception, but Katrina was Bush's Katrina) he's just a noisy gauche conservative who can't tie his own shoes. He says the quiet things out loud, but they all believe the quiet things.

Trump is bad. Trumpism is bad. But they aren't new.

Taking a knee

2 Comments and 10 Shares

Late last week, Donald Trump called any NFL player who kneels during the national anthem protesting police brutality a “son of a bitch” (recall that this is the President of the United States we’re talking about here) and said they should be fired (Ha! He said his catchphrase! From that TV show!). Naturally, NFL players took exception to this and over the weekend, many many more players kneeled, sat, or no-showed during the anthem. And there were many takes, from political commentators and sports journalists alike. One of the best was from Dallas sports anchor Dale Hansen, who deftly cut to the core of the matter in a short monologue:

Donald Trump has said he supports a peaceful protest because it’s an American’s right… But not this protest, and there’s the problem: The opinion that any protest you don’t agree with is a protest that should be stopped.

Martin Luther King should have marched across a different bridge. Young, black Americans should have gone to a different college and found a different lunch counter. And college kids in the 60’s had no right to protest an immoral war.

I served in the military during the Vietnam War… and my foot hurt, too. But I served anyway.

My best friend in high school was killed in Vietnam. Carroll Meir will be 18 years old forever. And he did not die so that you can decide who is a patriot and who loves America more.

The young, black athletes are not disrespecting America or the military by taking a knee during the anthem. They are respecting the best thing about America. It’s a dog whistle to the racists among us to say otherwise.

They, and all of us, should protest how black Americans are treated in this country. And if you don’t think white privilege is a fact, you don’t understand America.

Here’s a text transcript…it’s worth reading or watching. See also Bob Costas’ interview on CNN and Shannon Sharpe’s comments.

I shared this on Twitter last night and I still love it so much. This is a veteran (who we're supposedly offending) in Texas (red-bleeding state if there ever was such) who is on the correct side of the debate. The dog whistle comment is the whole reason this argument and "offense" exists. Because a person of color decided to speak out, it's time to rouse some rabble.

Great Job, Internet!: Kid’s go-kart goes apeshit, spinning him through time and space

1 Share

Before this week, the internet’s greatest go-kart-related phenomenon involved Tony Danza, who once took a hilarious and horrific-looking tumble in the days when he still hosted his own daytime talk show. Well, step down, Tony, because you’ve just been usurped by this human fidget spinner.

So captivated was the internet by the above footage that a few intrepid souls have made their own remixes. Some are simple, like the one layering in Hans Zimmer’s “Interstellar docking theme.”

Others are kind of eerie, like this one that finds a school of Asian carp summoning Go-Kart Kid from the heavens.

None, however, will be able to top the below video, which sets Go-Kart Kid on a kaleidoscopic journey through time, space, and meme culture. The boy is first sucked into a black hole, then spun off onto the heads of a cat, a basketball player’s nimble finger, and ...
