Pope Benedict searching for E.T?

I read an article about the Vatican's recent conference on possibilities for extra-terrestrial life with interest. Rev. Jose Gabriel Funes, director of the Vatican Observatory, presented results of an astrobiology conference.
Astrobiology is a newer field studying the origin of life and its existence elsewhere in the universe.

Certainly a discovery of extra-terrestrials, would impact our view of ourselves enormously. Now whether they be friend as in E.T. or foe and in "V" (I can't believe V is back!), that's another story!

But apparently a discovery alien life would not be a problem for the Catholic Church. Funes maintained that if intelligent beings were discovered, they would also be considered "part of creation."

May sports

If horses could talk....what was Alydar saying to Affirmed? For me, May through June is one of the most irritating times of the year in terms of sports. It is the time of the seemingly endless NBA playoffs. Now there's a possible area of study in time dilation. Time dilation is the idea in special relativity that moving clocks run slow. In other words, time does NOT fly during the NBA playoffs! But the one bright spots at this time in the sports calendar is the Triple Crown. Saturday's Kentucky Derby was quite exciting as a 50 to 1 longshot Mine That Bird took the purse.

Here's a website discussing some physics of horse racing. Secretariat's speed was estimated to be 16.764 m/s or 37.5 mi/hr. Secretariat is a bit earlier than my memory can recall, but what an athlete! Yes I called him an athlete. If golfers are athletes, then certainly the greatest thoroughbred in history is too.

End of semester approaches

I am sure my students do not like it, but something about the end of semester makes me want to fly through chapter sections at warp speed. While it takes almost 2 weeks to get through chapter 1, I am planning to go through chapter 6 in 1 - 1.5 classes. I hope they are awake tomorrow.

Summer Physics Camp for Girls!

If you are a young lady interested in physics you might consider applying to the University of Maryland's "Summer Girls" program. The Physics Department at UMCP has a program for rising 9th graders and rising 11th graders. Deadlines are in April and May. It is a day camp, so most participants have been from the Maryland/DC/Virginia area. Sounds cool though! Where was this kind of stuff when I was in high school?

Pulsar looks like cosmic hand

I'm always amazed by the objects in our universe. The x-ray nebula imaged by NASA's Chandra X-ray Observatory looks like a big hand reaching out towards a ring of knots above it. The color is of course fake - the lowest energy x-rays are red, while the highest energy x-rays are blue.

The bright blue spot at the center is a spinning neutron star, or a pulsar, PSR B1509-58. Neutrons are collapsed massive stars, in their dying phases as they have run out of fuel. They have huge magnetic fields and rapidly rotate causing them to generate fantabulous electromagnetic storms, driving away particles like electrons and ions.

Mt. Redoubt erupts!

Last night the Alaska volcano erupted 5 times! Amazingly, the height of the ash cloud has been estimated at 50,000 ft. If you are flying to Anchorage today, odds are your flight is cancelled.

There are no new pictures from the AVO as their web cam near the volcano is no longer functioning.

Mt. Redoubt alert level raised to WATCH

Alaska's Mt. Redoubt has been rumbling even more. The Alaska Volcano Observatory reports earthquakes numbering 40-50 per hour today. It's alert status has been raised to watch, which according to the AVO means

volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain.

Let's stay tuned volcano watchers!
