Instruments: A Problem in the Solution
Technology plays a key role in many fields, but it is not without limitations. Although technology has helped to make great advancements in data collection, there are times that the instruments themselves interfere in the measurements. The Oak Ridge Institute for Science and Education (ORISE) is hosting a problem-based challenge for undergraduate students. The challenge for undergraduates is to identify a situation in which an instrument interferes with its own measurements and data collection, and to propose a solution to the problem.

Ed Dumas, an affiliate of the National Oceanic and Atmospheric Administration (NOAA), explained a problem in using drones as an instrument to measure weather data: Atmospheric Turbulence and Diffusion Division (ATDD) has been making wind measurements for years using gust probes attached to fixed-wing full-scale aircraft, and this technology is well-characterized. Probes have been tested in a wind tunnel and the uncertainty in both the wind measurements made from the gust probe and the velocity and angles (pitch, roll, and heading) of the platform itself that are combined to make the final wind measurement have been accurately characterized. Because NOAA has been able to characterize the uncertainty in each of the components that comprise the wind measurement, there is confidence in the ability of the overall system to accurately measure winds with respect to the Earth.
However, similar measurements are not as well characterized from a multi-rotor platform. The biggest challenge is the disruption of the local airflow that is made by the multiple propellers used to keep the vehicle aloft. Eddies from these propellers can destroy the existing eddies in the atmosphere and severely contaminate the wind measurement.
Drones measuring wind gusts are not the only example of an instrument interfering with its own measurements. Another example is attempting to measure absolute zero on the Kelvin scale using a thermometer. At absolute zero (-273.15 degrees Celsius), atoms stop moving. Absolute zero cannot currently be measured because the particles of the thermometer are moving, which raises the temperature of the substance being measured by keeping the atoms in motion. While this temperature difference is an insignificant amount at temperatures that we experience daily, it is a major problem when measuring absolute zero. So while the thermometer readings can approach absolute zero, the current thermometer technology is not capable of accurately measuring it.
Nuclear Power: A Safe Future
There has been a significant increase in usage of nuclear power plants in the past 60 years, which comes along with an increased need for attention on nuclear safety. The Oak Ridge Institute for Science and Education (ORISE) hosted a problem-based challenge for undergraduate students. The challenge for undergraduates was to develop a plan to improve nuclear safety for the future. Congratulations to our scholarship winners!

Radiation Exposure: What Not to Fear
Despite living in a world of constant radiation exposure, people have a negative association with the word “radiation.” In March, the Oak Ridge Institute for Science and Education (ORISE) hosted a problem-based challenge for undergraduate students. The challenge for undergraduates was to develop a strategic communication approach for the general public on the everyday occurrences of radiation, the benefits, risks, and safety of all types and uses of radiation.
