While thousands rode carnival rides and noshed on funnel
cakes at the
Spring Fair on the Homewood campus, the
Department of Physics
and Astronomy offered up another kind of fun: the first
Physics Fair. Held at the Bloomberg Center for Physics and
Astronomy, located on the north end of campus, the free
event was intended to introduce physics — and Hopkins
— to local high school students.
12:30 p.m. Nine high school teams compete in Round
One of the Physics Bowl in the auditorium, answering
questions like, Which of the following particles is the
heaviest-A) electron, B) proton, C) photon, D) neutron, E)
neutrino? [Answer: D]
1 p.m. The first of Inge Heyer's Hubble Space
Telescope presentations begins in room 361. Visitors wander
up to the roof to search for sun spots using the
telescope.
1:15 p.m. Grad student Ting Yong Chen helps
Scavenger Hunt teams use a scanning electron microscope to
inspect a fly's 10-micron compound eyes and answer the
question, How many eyes does a fly have? (Answer:
20,000!)
2:15 p.m. The Hopkins Blue Jay mascot shows up for
Cal Walker's lecture on quirky events and principles, which
includes footage of the ill-fated Tacoma Narrows Bridge
twisting and swinging in the wind.
2:45 p.m. The High Rise Contest begins in the
second-floor rotunda. Baltimore Polytech teacher Jamie
Rittner hands out toothpicks and mini-marshmallows.
Contestants have 20 minutes to build the highest tower that
can stand on its own for 60 seconds. The winner: a
triangle-based geodesic structure 45 centimeters high,
built by the Anderson family of Ellicott City: Katherine,
12, Chris, 14, and their scientist parents, David and
Vilma.
3:15 p.m. In the Rotunda is a popular attraction: a
liquid nitrogen demonstration. Grad students use the
compressed liquid to create a frothing volcano that spills
across the linoleum floor, while visitors dip fresh flowers
into the liquid and shatter them like glass.
3:30 p.m. Three Physics Bowl teams assemble in the
auditorium for Round II.
4 p.m. The awards ceremony honors Physics Bowl
winners and other of the day's participants with trophies
and gift certificates.
