Balloon Juice

Come for the politics, stay for the snark.

Tide comes in. Tide goes out. You can’t explain that.

The worst democrat is better than the best republican.

There are more Russians standing up to Putin than Republicans.

Every reporter and pundit should have to declare if they ever vacationed with a billionaire.

If you are still in the gop, you are either an extremist yourself, or in bed with those who are.

Proof that we need a blogger ethics panel.

Some judge needs to shut this circus down soon.

75% of people clapping liked the show!

We still have time to mess this up!

Republicans choose power over democracy, every day.

I’m starting to think Jesus may have made a mistake saving people with no questions asked.

Insiders who complain to politico: please report to the white house office of shut the fuck up.

Why is it so hard for them to condemn hate?

A thin legal pretext to veneer over their personal religious and political desires.

Jesus watching the most hateful people claiming to be his followers

When someone says they “love freedom”, rest assured they don’t mean yours.

This really is a full service blog.

We need to vote them all out and restore sane Democratic government.

We’re watching the self-immolation of the leading world power on a level unprecedented in human history.

Putin must be throwing ketchup at the walls.

Republicans: slavery is when you own me. freedom is when I own you.

There are a lot more evil idiots than evil geniuses.

A snarling mass of vitriolic jackals

It’s easy to sit in safety and prescribe what other people should be doing.

At long last, they have invented cloaking for blind people. Metamaterial-based cloaks make objects different from their surrounding appear just like their surrounding…Here, inspired by invisible core-shell nanoparticles in optics, we design an approximate elasto-mechanical core-shell ‘unfeelability’ cloak based on pentamode metamaterials. To summarize, that princess can finally get some fking sleep. Science kicks butt. …

This post is in: Science & Technology

Along with writing 2001: A Space Odyssey, proposing the geosynchronous satellite and a questionable pedophilia charge, Arthur C. Clarke once famously observed that any sufficiently advanced technology is indistinguishable from magic. Clarke undoubtedly had in mind a visitor from the mid 19th century or earlier, but things move faster now. For example, the other day …

Some other topics to muse while I put off going to bed. * A philanthropist named Mark Bent has an excellent sense of pressure points, areas where a modest investment and limited technogy can yield a huge improvement in many lives. Too often would-be benefactors decide in advance what they want to give and then …

No Ship That Small Has A Cloaking Device

by Tim F|  November 11, 200612:53 pm| 19 Comments

This post is in: Science & Technology

Science has dealt another blow to those who draw their scientific knowledge from Star Wars films. Contrary to the famous line in the Empire Strikes Back,a new engineering approach called metamaterials can potentially cloak any size ship as long as you know what energy wavelength the other guy plans to use. So much for verisimilitude, …
