Jumping in figure skates

Figure skates are not exactly the easiest things to jump in. They are stiff and restrict the motion of your foot and your ankle. Which makes me wonder how this affects the way the rest of your leg moves while jumping. Haguenauer, Legreneur, and Monteil (2006) examined national and international figure skaters jumps comparing their … Continue reading

An intro to the science of figure skating jumps

  There are primarily six different jumps that figure skaters perform. The jumps vary based on edge vs toe (do you take off on an edge, or stick your toe pick in and vault into the air), entry edge (inside or outside, and even toe jumps have this characteristic, foot (inside or outside of the … Continue reading

Does the cyclist or the equipment matter more?

There are many ways that a person can modify a bike to give themselves an advantage and with two major cycling events (Tour of Alberta – road cycling and FISE world action sports festival – a couple different BMX events and mountain bike slope style) in Edmonton in September these modifications have been on my … Continue reading

Science Videos that Rock

  Drafting is something that you hear about in a number of different sports. Basically, when you draft, you sit very close behind someone else (and by sit I mean paddle, swim, bike, run, etc). The idea is that you spend less energy than the person at the front. But how does this work? A … Continue reading

Floating photovoltaics: Do they reduce evaporation?

I saw this interesting article about installing floating photovoltaics on Lake Mead and Lake Powell in the U.S. as a means of generating power using renewables and reducing some of the significant evaporation from the two lakes. It makes sense that the solar panels will generate electricity, but I’m curious about two of the claims: 1) how much … Continue reading

How does the Aurora Borealis actually work?

Guest Blogger: Alex Diaz I have been looking to the sky since I was a very young boy. When I first saw the Northern Lights or, Aurora Borealis, they seemingly appeared within the blink of an eye. Nothing but green surrounded me and I remember wondering how does such a dazzling display of lights come … Continue reading
