Why Richard Feynman can’t tell you how magnets work

08 Nov

But seriously, f*ckin' magnets, how do they work?

It's a very good question, but the truth, according to none other than Richard Feynman, is that it's also a very hard question to give non-scientists an answer on. The trouble: Magnetism is one of those things that's just damn difficult to understand in terms of analogy to stuff the average person already knows. The only way to answer this kind of reductive "why" question, Feynman says, is to put the questioner through an elaborate education in physics, at which point they will emerge—like a hobbled butterfly—equally unable to answer the question in a simple way.

Basically, ICP is doomed to receive nothing but unsatisfying answers on this topic until they enroll themselves in an evil clown Ph.D. program.

Video shows asteroid discoveries since 1980

08 Sep

Just in case I wasn't already in awe of the scientific progress made during my own lifetime, Lauren Submitterated (it's a verb now) this video showing the mind-blowing numbers of asteroids that have been discovered since 1980. Created by Scott Manley—and with some very lovely music, I might add—the video shows new discoveries in white, then changes their color to reflect position in relation to the inner solar system. Earth crossers are red. Earth approachers are yellow. All others are green.

Manley's included a lot of good information about what the patterns of where and when new asteroids appear in the video tell us about astronomy over over the last 30 years.

Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video.

As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner.

At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths.

How to turn carrots into bacon

09 Aug

Via the BB Submitterator, reader kentbrew says,

Here is an instructional Flickr set that shows you exactly how to turn the carrots you allowed to grow way beyond the point where they were edible by human beings into something verrrry close to bacon.
As an herbivore, I heartily approve!

Adorably deadly Mini Cannon returns

08 Aug

Boing Boing reader gatetree points us to a comeback video from the Mini Cannon (blogged earlier by Mark) and notes,

The mini-cannon videomaker seems to have followed almost every suggestion from the boingboing post of his first video in May.
