Model: This is some type of representation (conceptual, mathematical, physical, computational) of a real object. Example: a model of a bouncing ball would produce results that agree with a real ...

I admit it, I love my job(s). I love doing science, and I love reporting science. In particular, I love it when my expectations are confounded, as they recently were in a paper I read. In this ...

Here's how to get more bounce from a normal tennis ball - buddy it up with a heavier ball for twice the impact. Hold a ball in each hand and decide which ball weighs more (has greater mass). It might ...

[T-Kuhn]’s Octo-Bouncer platform has learned some new tricks since we saw it last. If you haven’t seen it before, this device uses computer vision from a camera mounted underneath its thick, clear ...
