Two galaxies merging

Here is one a beautiful image of two galaxies merging.    Hope you enjoy it! Two Galaxies Merging (from Astronomy Picture of the Day).

(Note there are many other pictures to be found at Astronomy Picture of the Day, look at the current entry, and if you have time look through the archives.)

Mars Science Lab Curiosity.


On Friday, September 28, Nilton Renno (from the University of Michigan Department of Atmospheric, Oceanic and Space Sciences) gave a talk to the club entitled “Mars Science Lab Curiosity.”

Back in March, Nilton had given us a talk entitled “Deliquescence and Liquid Water on Mars.” In short, it is now known that liquid salty water is present on the surface of Mars, at least in some locations and during some parts of the Martian year (most of the time water is present in the form of ice).

There was another spacecraft on its way to Mars, the Mars Science Lab Curiosity, which was scheduled to land in August. After his first talk, Nilton agreed to come back for a second talk, after the lander made it to Mars. This was a somewhat risky proposition since many past attempts to land spacecraft on the red planet have ended in failure, and a talk about a failed Mars mission might be rather short.

As it happened, Curiosity successfully landed on the surface of Mars on August 6. There were only a few minor issues. Thus Nilton's second talk on September 28.

During the September talk, Nilton described the mission and its goals. Unfortunately it will take some time to sort out the science results. At the time of the talk, Nilton could only give us a few hints.

AA OSA Special Tour on Tuesday, 23 October

The Optical Society of American (OSA) is having a Special Tour next week, on Tuesday, 23rd October.  We will be meeting at the Eastern Michigan University Physics & Astronomy Dept. to see and hear about their new Planetarium facility, the digital projection equipment and the Sherzer Observatory / telescope on the roof.  We will hear about the departmental facilities, faculty and areas of exploration.  I encourage everyone to attend, as this is really going to be an interesting tour.

Saturday Morning Physics (October 6)

On October 6, 2012 Bing Zhou, (Professor and Associate Chair of Physics at the University of Michigan) gave the talk "The New Particle Discovery at LHC with the ATLAS Experiment." This was the first Saturday Morning Physics talk for Fall 2012. Saturday Morning Physics is hosted by the University of Michigan Physics Department.


After decades of searching, evidence for the existence of the Higgs boson was finally found at CERN. This is a tremendous step forward in Physics made possible through the efforts of the LHC experiments (ATLAS and CMS). These experiments were a international collaboration involving many institutions including the University of Michigan. Professor Zhou presented a brief history on the Higgs hunting in the past decades. She reported the experimental evidence of the new particle discovery and ongoing research related to the studies of the new particle with the ATLAS experiment.


What is the Higgs boson? In the 60's a group of physicists independently proposed the following idea: add a new field permeating space that gives particles mass, and a new particle (or a group of related particles) that creates this field. These are usually called the Higgs field and the Higgs boson(s) respectively, after Peter Higgs. Peter Higgs is one of the physicists who originally proposed the mechanism and is currently professor emeritus at the University of Edinburgh. Professor Higgs is shown in the slide above.

AA OSA Presentation on How to Micro-Machine with Lasers


Hi everyone,

We have a very interesting presentation tomorrow night (Tuesday, 09 October) with Philippe Bado (Translume) and Larry Walker (Clark-MXR) talking with you about "How to Micro-Machine with Lasers".  Please see the attached meeting flyer and post it in a prominent location for others who might be interested.

The location: the University of Michigan North Campus, EECS Room 1005, Ann Arbor Michigan.

Minute Physics

We ran across this site: Minute Physics .

There are a number of interesting short videos covering various physics topics. At the time I post this, the video at the top was "Why is it Dark at Night?", which caught my eye, but there are other interesting videos as well.

If your first language is English and you have no desire to translate videos into other languages, ignore the language stuff.
