We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science, and act before it’s too late.

We have a choice in what we believe, but we do not have the freedoms to choose what is scientific or true.

“Why Climate Deniers Have No Scientific Credibility - In One Number”

Deniers of climate science are fond of the following wacky idea: That the scientific community does not agree on the cause of climate change. It’s time to bury that idea like a senile dog hiding a ham bone: Somewhere where we’ll forget about it forever.

According to some recent data-mining of the scientific literature, 0.17% is the percentage of peer-reviewed scientific papers in the past 21 years that offer a scientifically-viable alternative to human-caused global warming.

Only 24 of 13,950 articles (0.17%) try to make this case in a scientific manner. If any of them were right, they would have been cited hundreds of times, instead of forgotten forever.

Among the public, denying global warming is a very popular and very influential idea. Among scientists, it holds slightly less than no water.

Star Wars Astromech Droid by PodpadStudios

That droid is fully operational! Lovingly registered as “Zoe”, this unique replica astromech from the Star Wars series has her own router, webcame, and IP address, as well as a fire extinguisher, utility and claw arms, periscope, smoke machine port (that can shoot unsuspecting kids in the eyeballs), and even a holographic projector that displays Princess Leia’s distress message onto a nearby wall. Wired up with glow-y lights and el-wire, Zoe has got it all except for the fully autonomous, plucky attitude and knack for accidentally falling into zany adventures in space. Check out the full detailed report over at Instructables, with some video of the holo-projection and Christmas Tree action below:

If you were teaching a graduate seminar in public policy and challenged your students to come up with the most difficult possible problem to solve, they’d come up with something very much like climate change. It’s slow-acting. It’s essentially invisible. It’s expensive to address. It has a huge number of very rich special interests arrayed against doing anything about it. It requires international action that pits rich countries against poor ones. And it has a lot of momentum: you have to take action now, before its effects are serious, because today’s greenhouse gases will cause climate change tomorrow no matter what we do in thirty years.

No candy for you, Kevin Drum. Your completely logical point and 110% truthy take on the political difficulties of dealing with climate change is like the worst trick when I asked for a treat.

But it’s something we need to hear.

Dogma vs. Scientific Experimentation, as told by bunnies assembling a puzzle.

Bad Astronomy: THIS is why we invest in science

Because when we invest in science, when we invest in space, when we invest in exploration, we always, always get far more back in return than we put in. And not just in dollars and cents.

See that picture above? It shows a new type of rocket engine design. Usually, fuel is pumped into a chamber where the chemicals ignite and are blown out the other end, creating thrust. The design pictured above does this in a new way: as the fuel is pumped into the chamber, it’s spun up, creating a vortex. This focuses the flow, keeping it closer to the center of the chamber. In this way, when the fuel ignite, it keeps the walls of the chamber cooler.

So what, right?

Here’s what: using this technology — developed for rockets for NASA, remember — engineers designed a way to pump water more quickly and efficiently for fire suppression. The result is nothing short of astonishing:

One series of tests using empty houses at Vandenberg Air Force Base compared [this new] system with a 20-gallon-per-minute, 1,400 pound-per-square-inch (psi) discharge capability (at the pump) versus a standard 100-gallon-per-minute, 125 psi standard hand line—the kind that typically takes a few firemen to control. The standard line extinguished a set fire in a living room in 1 minute and 45 seconds using 220 gallons of water. The [new] system extinguished an identical fire in 17.3 seconds using 13.6 gallons—with a hose requiring only one person to manage.

In other words, this new system put out a fire more quickly, using less water, and — critically — with fewer firefighters needed to operate the hose. This frees up needed firefighters to do other important tasks on the job, and therefore makes fighting fires faster and safer.

Nanotechnology and Chocolate Sauce - The Battle Escalates

Water is a cruel moistress. On one hand, we’re mostly made of the stuff. Our biology depends on it, and most of Earth’s chemistry takes place in aqueous environments. It’s water all the way down.

On the other hand it can really ruin your day. Corrosion, contamination, stains, dead iPhones … they can all be attributed to the fact that water sticks to stuff, and stuff sticks to water. But hydrophobic surfaces repel water. Wouldn’t it be nice if we could make say, a pair of nice expensive shoes, completely hydrophobic?

A cool product called NeverWet looks like it can do just that. By coating surfaces with special nanoparticles, they become superhydrophobic. Water just falls right off, as does oil, ketchup and mud. Or anything else.

The video above is pretty amazing. Here it is on clothes. And here’s what your finger would look like if it was superhydrophobic.
