And what was the purpose of the steam? Check out this video for the answers: Note the shout-out in the video toContinue reading “The Road to Entropy – The Newcomen and Watt “Steam” Engines (videos)”

Riddle me this: why does a gas deviate from ideal behavior?
Years ago, during on-campus interview season at college, a friend of mine majoring in electrical engineering told of how difficult one of his interviews was. “The interviewer asked me how an oscilloscope worked, and I carefully explained how to plug in the different wires and then how to adjust the knobs and so on. HeContinue reading “Riddle me this: why does a gas deviate from ideal behavior?”
Why Do Balloons Float?
An experimental balloon takes its inaugural flight in August 2020. This particular balloon can change altitude by shortening or lengthening a cord attached the top and bottom of the balloon. Shortening the cord compresses the balloon which makes it descend while lengthening the cord expands the balloon allowing it to ascend. Photo courtesy of ThinContinue reading “Why Do Balloons Float?”
How to conduct powerful science? Check your ego at the door.
Observe nature, take measurements, and then propose as many hypotheses as you possibly can that are consistent with the data. In this way, you shift the focus from a negative conflict between scientists, each embracing their own individual hypothesis, to a positive, exciting, and team-based conflict between ideas in which technical debate among those with differing perspectives is encouraged in order to learn and not to win.
