The Ig Nobels

September 13, 2013
Since I mentioned the live webcast of the 22nd first annual Ig Nobel prizes, I suppose I should reveal the winners to those who were unable (or dare I say uninterested) in watching the results.

The prize for medicine has gone to a team of Japanese researchers for their study of the effect of opera music on mice who have had heart transplants. It may sound strange, but if successful, their results could produce better methods of helping humans with heart transplants to recover quicker and healthier.

The prize for psychology went to a team of (predominantly) French scientists for their study of people who think they are drunk also tend to think they are more attractive. I suppose instead of the beer goggles, this is more like the beer mirror.

The prizes for biology and astronomy were merged this year and awarded to a multi-national team of scientists who discovered that dung beetles can navigate using the Milky Way galaxy as a reference.

The prize in physics has gone to an Italian team of physicists for calculating that some people could run on top of water, if both the people and the water in question were transported to the surface of the Moon.

The prize for chemistry has gone to a Japanese team for studying the complexity of the mechanism by which cutting onions makes people cry. It would seem that multiple chemicals and reactions are involved, making this effect more complicated than previously realized.

The archaeology prize has gone to a pair of North American researchers who cooked and swallowed (without chewing) a dead shrew and then analyzed their own droppings to determine which bones the human digestive system broke apart and which were left behind. (Presumably this was to determine which combination of bones in archaeological sites indicates human presence, rather than just a fraternity initiation)

The prize for probability has gone to a multinational team of statisticians for studying the probability distribution of cows standing up or lying down. They determined that the longer a cow has been lying down, the greater the probability of it standing up, but there is no correlation between standing time and the decision to lie down.

Those are the science related awards - there are always a couple that are for things like engineering safety and public health, but those can be found elsewhere.  Once again the Ig Nobel committee has done a great job of recognizing research that makes people laugh, then makes them think.
 

Feynman Lectures Online

September 13, 2013
There is great news today for physics students around the world - the legendary Feynman Lectures on Physics are now available online in glorious HTML & LaTeX. They can be accessed through the website: http://feynmanlectures.info/flp.html

For those not familiar with the story, long ago (the early 1960s) the Nobel Prize winning physicist Richard Feynman was working at CalTech when someone brought up the idea of an introductory physics course for first year students, which would present many of t...

Big Brother is Listening...

September 4, 2013
OK, so the title is just a tad over-dramatic. However there is an interesting new software tool being developed for tracking the time and date of phone calls or wiretaps, and it requires no special hidden devices or spyware on the targets phone or home. It is simply a matter of listening to the background hum of electrical appliances.

People generally assume that electricity is constant and unchanging. But it isn't. The electrical current that runs all of your household appliances from the ran...

Back to School

September 3, 2013

Some loyal readers will recognize this entry as a repeat from the last two years. I have had requests from some of my readers to repeat it again this year, and so I must once again acquiesce to the masses...

To all the students starting University, enjoy this time of your life. Long ago when I started, a prof told me that this is the start of your real education. Now you get to choose your own courses and your own field of study. It is entirely up to you to decide what to do with this chance.

I...

Free Schoolware

September 3, 2013

This is a completely trivial posting, but some friends requested this information and I thought others may benefit from it. Apparently some parents are having financial problems due to purchasing software for their children's school needs. So here are a few links to free (and legal) alternatives which are as good as or better than their commercial counterparts.


Office Software: OpenOffice (replaces Microsoft Office or the Corel Packages)


Mathematics Software: SageMath (basic alternative to Math...

The Perseids

August 11, 2013
This weekend skywatchers in areas with clear weather and minimal light pollution will have the opportunity to watch the Perseid meteor showers again. I am lucky this year to be spending some time at a remote private dark site which has unobstructed views of most of the sky, and absolutely no light pollution. Now I just need to hope for no cloud cover...

The Perseid meteor showers happen quite regularly every August. They are caused by debris from Comet Swift-Tuttle which passed by the Earth lo...

Kerberos and Styx

July 8, 2013
Frequent readers of my blogs may recall back in February I wrote about a contest to name the two newly discovered moons of the planet Pluto (I don't care what the IAU says, Pluto deserves to be a planet). The results are in, but not without a measure of controversy.

The two moons have been named Kerberos and Styx. As the planet furthest from the Sun, Pluto was named for the Roman god of the underworld. The first three moons that were discovered were named Charon (the boatman who ferried the sp...

Bionic Printing

July 8, 2013

By now most of the sort of people who read my blogs are aware of the rise of 3D printing. These are the new machines that use molten plastic (or other substances) to print objects layer-by-layer. They are already being used to produce everything from cable clips, to replacement parts, to toys, to sculptures, and as the prices are now dropping below the $1000 range they can be expected to be a common household item over the coming decade. 

However researchers at Princeton University have found...

Hempel's Paradox

July 7, 2013
For those who are interested in serious science news, you may want to skip today's article. It is a fascinating paradox in science, but it is more than a bit philosophical as well. This is actually a well known paradox that has been discussed and debated for a long time, but it is still worth pondering.

The experimental method in science is very straightforward. A scientist develops a hypothesis, and then goes out into the world collecting data. That data might come from observing plants or an...

Voyager Ventures Beyond the Edge

July 3, 2013

This week the space sciences community has also announced new results from the Voyager 1 space probe, first launched more than 35 years ago and still a valuable scientific tool. The NASA probe has entered a new region on the edge of the solar system, right as it prepares to move through interstellar space.

It has been now revealed that Voyager sensors have detected a sudden drop in particles flowing from our own sun (in fact it is a drop of about 99.9%), and a 10% increase in galactic cosmic ...
