BERLINER HELICOPTER
Emile Berliner was an inventor and aviation enthusiast. In 1907 he began to experiment with vertical flight. In 1920,
his son, Henry, came to College Park to conduct tests on an experimental helicopter. A number of experiments were conducted
with different designs until on February 24, 1924 the first successful controlled helicopter flight took place at College Park. Henry Berliner
was able to reach and maintain an altitude of 15 feet for 90 seconds and was able to maneuver the helicopter at a speed of 40 mph
in a radius of approximately 150 feet.

FIRST TELEGRAPH, TELEGRAPH LINE
Samuel F.B. Morse reportedly received the first telegraph message in Bladensburg, in 1844, before his famous "What Hath God Wrought" message between Baltimore and Washington. His telegraph wire had been strung along the railroad right of way. Ezra Cornell, founder of Cornell University, lived in Bladensburg and is said to have invented the telegraph pole.

Related Text: Associate Professor of Mechanical Engineering Ken Kiger spent the fall of 2003 at the J.M. Burgers Center at the
Technical University of Delft performing research for the development of improved Particle Image Velocimetry (PIV) techniques for in
vivo flow measurement. The goal of the research was to try and adapt quantitative imaging techniques commonly used in
engineering fluid mechanics research for use in measurement within living systems. For this specific example, his research group
wanted to be able to measure the flow profiles and the hydrodynamic shear stresses applied to the walls of an embryonic avian heart.
The biomedical colleagues working with Kiger's group have previously conducted experiments using chicken embryos as a model,
which indicate that altering the flow pattern through the primitive tube-shaped heart of very young embryos typically results in
significant defects within an adult four-chambered heart. They have speculated that this is a result of the change in shear stress
patterns caused by the flow alteration, but until now, they did not have the means to quantify specifically how the shear stress
in the heart was altered.
