Something to help your kids understand physics

Is a head-on crash of two cars driving 50mph each equivalent to a crash of a single car driving 100mph against a solid wall? An easy answer if you think about the energy involved rather than about the force and action and reaction.

These two clips from Mythbusters will make a physics lesson cool and memorable for kids, and the rest can just enjoy the carnage.

Back on the web

I haven’t really had a website since my time at university, which, including my post-doc, is getting to be almost 8 years ago. I guess it is time to establish some web presence again. I will be starting by making my university publications available as PDFs.

BTW, my first website was on Geocities, back when it started in 1995/96. That is when Pentium 100Mhz was a fast processor.
