Science ABC: the eddy currents, and the coolest video you’ll see today

Tuesday, February 23, 2010

2 Comments

Eddy currents are electrical phenomena that take place when a conductor is exposed to an oscilation of the magnetic field due to the relative motion of the field source and conductor; rewind. You have a conductor, say a copper tube, and a magnet. One moves relative to the other and you’ve got current (basically a [...]

Could life exist in a different Universe than ours ?

Monday, February 22, 2010

1 Comment

Whether intelligent life exists in our universe is a long debated problem. But for some scientists, there’s something even more interesting than that: is there life in another universe? A definite answer is impossible, especially since it’s not even clear if such a universe exists, thoush researchers have speculated such an existance for more than [...]

Oceans of diamonds on Uranus

Saturday, January 23, 2010

1 Comment

A new research published in Nature Physics showed that there may be oceans of diamonds (literally) on both Uranus and Neptune. The first ever study conducted on the melting point of diamond concluded that at that certain point, it behaves just like water, with the solid form floating in the liquid form (just imagine icebergs, [...]

The most absurd explanation you’ll hear today

Tuesday, January 12, 2010

4 Comments

Well, the talk is on homeopathy, but this is really not about homeopathy. It’s about the “physics” explanation, and how it manages to be so absurd that it basically urinates on pretty much modern science in just 5 minutes (which is quite an achievement, truth be told). With no disrespect, how she got the “Dr.” [...]

Neil deGrasse talks about e=mc^2

Neil deGrasse is definitely one of my heroes, and the simplicity through which he manages to explain even the most complicated things is absolutely amazing. After the symphony of science, here’s him in a short video talking about what is perhaps the most important equation to date.

Scientists create the first molecular transistor

Monday, January 4, 2010

0 Comments

Researchers from Yale University succeeded in what seemed to be an impossible task: they’ve created a transistor from a single molecule. In case you don’t know, a transistor is a “semiconductor device commonly used to amplify or switch electronic signals” (via wikipedia). The team showed that using a single benzene molecule attached to gold contacts is [...]

Water and fog found on Titan, Saturn’s moon

Friday, December 18, 2009

1 Comment

As I was writing in a previous post, Titan is quite unique, in that aside from our planet it’s the only place in our solar system where significant quantities of liquid are to be found (though most are liquid ethane and methane). That doesn’t seem to make much of a difference considering the chemistry of [...]

LHC produces first results

Thursday, December 17, 2009

Since the Large Hadron Collider went back in business, all sort of rumors have been circling the scientific circles (and not only). However, until these rumors are proven wrong or right, the first official paper on proton collisions from the Large Hadron Collider has been published in this week’s edition of Springer’s European Physical Journal [...]

Blue whales singing lower every year, baffled scientists say

Monday, December 14, 2009

0 Comments

Blue whales are not only the biggest living creatures in the world right now, but the biggest ever to have ‘walked’ the face of the earth; they’re also the loudest for that matter. After recovering from near extinction in the beginning of the 20th century, blue whales are finally getting a part of the respect [...]

Dark matter discovered, or at least rumor has it

Thursday, December 10, 2009

2 Comments

Well, rumors and science never go well together, especially when it goes to something as important as the work going on at LHC, who just got back in business a short while ago. My first reaction was to believe it was just a rumor. However, after hearing and reading many articles on this (including something from [...]
