DASTOW '05 Is On The Move|
To Summer: New Date 6/23
DASTOW 2004 (Click on image for larger version.)|
Daughters and Sons To Work (DASTOW) day for Fermilab employees and their
families is moving to summer for 2005, with the new date set for Thursday,
The usual DASTOW date on the fourth Thursday in April has increasingly conflicted
with scheduled school activities, including career days at some area middle
schools. The new summer date is an experiment to offer Fermilab-related career
activities for middle-school students, as well as expanded outdoor activities
for all participants. Also, please note that DASTOW and the Earth Day tree-planting
are separate events this year, and are being held on different dates
(see story below).
Watch Fermilab Today for further DASTOW announcements as June
23 draws nearer.
Tree Planting For Earth Day
Takes Place Friday, April 22|
Tree planting at one of the past Earth Days at Fermilab.|
Fermilab's Earth Day tree-planting activities for employees and their families,
sponsored by Roads and Grounds, will be held on Friday, April 22 with a rain date
of Monday, April 25. Bring a shovel, and wear boots and gloves
(and this year, bring your own lunch, too). The area to be planted this year
is directly west of
Planting begins at 11 a.m.
And remember: Earth Day tree-planting and DASTOW are separate events for 2005,
taking place on different dates.

One Hundred Years of Uncertainty
by Brian Greene
Just about a hundred years ago, Albert Einstein began writing a paper that secured his place in the pantheon of humankind's greatest thinkers. With his discovery of special relativity, Einstein upended the familiar, thousands-year-old conception of space and time. To be sure, even a century later, not everyone has fully embraced Einstein's discovery. Nevertheless, say "Einstein" and most everyone thinks "relativity."
What is less widely appreciated, however, is that physicists call 1905 Einstein's "miracle year" not because of the discovery of relativity alone, but because in that year Einstein achieved the unimaginable, writing four papers that each resulted in deep and formative changes to our understanding of the universe. One of these papers - not on relativity - garnered him the 1921 Nobel Prize in physics. It also began a transformation in physics that Einstein found so disquieting that he spent the last 30 years of his life in a determined effort to repudiate it.
In 2001, collisions between bicycles and motor vehicles in the United States
728 fatalities and 45,000 injuries. Fortunately, collision rates
have been declining, about 2% per year. Hopefully we can continue
this trend by examining causes and taking preventive actions.
The Federal Highway
Administration found that there are five major causes for bicycle-motor
29% Bicyclist failed to yield
22% Motorist failed to yield
19% Either turned into path of other
9% Motorist overtaking bicyclist
The "bicyclist failed to yield" category primarily involves children not yielding
the right of way at intersections or upon entering a street from a driveway
or curb. In "motorist failed to yield," drivers proceed through an intersection
or enter a street from a driveway or alley without yielding. With "turned
into path," either the motorist or the bicyclist turns into the path of the
other. With "motorist overtaking bicyclist," the collision is caused by the
bicyclist swerving, or the motorist not seeing or misjudging the distance
to the bicyclist.
A major factor in most collisions is a lack of awareness and/or attentiveness
on the part of the bicyclist or the motorist. When riding a bike, you should
assume that motorists don't know you're there and ride in such a way that
they won't hit you even if they don't see you. When driving a motor vehicle,
stay alert for the presence of bicycles. If you are about to pass a bicyclist,
slow down enough that you can stop if necessary, or pass wide if you can see
Have a great day and let's work safely all week!
