From College Chemistry to Capitol Hill: One Student’s Journey to the Finals of a Nationwide Competition

Going to the finals of the Community College Innovation Challenge (CCIC) changed my life forever. Held in Washington, D.C. on 14-16 June 2017,  I had the opportunity to meet multiple representatives from respected institutions such as the National Science Foundation (NSF) and the American Association of Community Colleges (AACC) while presenting my project to congressmen, scientists, businessmen, and other professionals on Capitol Hill. The project I presented was called Project …

Numerical Weather Model Adjusted For Eclipse Forecast

There are a lot of experiments and observations that will be made during the eclipse on Monday, but I just heard of one tonight that is right up my alley! First, I have to explain some things. One of the better high-resolution weather models we use every day is called the HRRR for High-Resolution Rapid Refresh model. This model does an excellent job and has sophisticated physics that runs at …

A celestial celebration of Earth’s place in the Cosmos, mapped onto Earth

It’s been repeated now a million times, but its grandeur bears another announcement: on August 21, 2017, a long-awaited total solar eclipse will cast the moon’s narrow shadow directly across the United States. The reverse perspective–the vantage that humans have always had, although they haven’t necessarily understood it–is that the sun will be gradually but briefly blocked by the invisible day-time visage of the new moon. Although the eclipse will …

Sol 1787: Less Driving, More Science

At the start of operations, we discovered that the drive yestersol faulted prematurely after about only 15 m, which was roughly half the expected distance. The drive halted because one of the middle wheels experienced a large up and down motion as if going over a large rock.
