What’s the Area of Part of a Circle?

  • September 9

The bright colors and disconnected nature of this artwork by Joel Froment are just begging to be appreciated mathematically. Here, a Greenhill School high school student, tej, uses some "circular logic" to investigate area and circumference.... CONTINUE READING

What’s the Mathematical Mystery Here? Fountain

Which mass travels faster?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. At the Ronald Kirk Bridge, talkSTEM members, Michael and Mary, did an experiment to see which would travel down the Trinity River the fastest - the thicker or thinner stick. Make your hypothesis - would heavier or lighter mass travel faster? Watch the video to find out!... CONTINUE READING

What is the speed of the water?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. At the Ronald Kirk Bridge, the talkSTEM team found a natural whirlpool in the Trinity River. The video explores a strategy for estimating the speed of water. What other strategies could you use to measure the speed of a liquid? What about objects traveling through air instead of water? At talkSTEM, we know that math isn't always perf... CONTINUE READING

How can we measure arches and lines?

  • September 9

Over 7 million people visit the West End Historic District every year! What if they all stood in line to visit? What would that look like? We use math to help us understand this gargantuan number! This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

How tall are the gateway arches?

  • September 9

West End Historic District is marked by these beautiful brick arches and we wonder what is the tallest person that could walk under them? We used math to figure that out. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

Is the pool circular?

  • September 9

How can you tell if an object is circular? We show you two methods for determining if an object could be a circle and invite you to try it out yourself! This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
