It’s summertime in this part of the world, which means lots of people spending time at the beach, playing in the waves, building sandcastles, and admiring the dunes. As you’re strolling along, with the sun setting in the distance, you notice an interesting rippling pattern in the warm sand underfoot. Why does it take this...

Now emerging from a long, grey winter in southern Ontario, our daily walks around the neighbourhood are becoming a technicolour experience, with flowers popping up and trees leafing out everywhere. (C)Ian Lee Daffodils dripping in their canary-colored finery, tulips blazing in fiery displays, pink canopies dancing overhead and every shade of green gleaming underfoot; spring...

All fingers and toes crossed for clear skies in southern Ontario on April 8th around 3:20 pm! At that moment, in the skies directly above Niagara Falls, ON, the alignment of the Sun, our moon and our own planet will result in a once-in-a-lifetime spectacle – a total solar eclipse. A total solar eclipse is...

Cleo, my furry sheepdog (right), eats two scoops of kibble every morning while her smaller sister, Molly, only eats one. That makes sense at first glance when you see them together: Cleo is much bigger than Molly so needs more fuel in the tank. But, if we want to be a bit more precise, Cleo...

This time of year in the northern hemisphere, when temperatures drop and the sun is shining, we get the opportunity to take some beautiful photos such as this one of partially frozen soap bubbles taken by Peter von Bagh: The play of light, the ice forming from nucleation points, wave interference effects in the thin...

Imagine if people had their own built-in compasses – this would be hugely helpful to us in navigating around in Earth’s magnetic field. Unfortunately, humans can’t innately sense Earth’s field, but a particular type of bacterium can and puts its internal compass to good use in orienting itself in its environment. This magneto-sensing trait is...

“Fish on!” It sounds like a call from one friend to another while bobbing on a lake in northern Canada on a summer afternoon. In northern Thailand, in the summer of 2018, these words had a more profound meaning – they were the code words used by the rescue team when one of the trapped...

What do giraffe spots, garlic bulbs, tree canopies, and ice formations all have in common? They are just a few gorgeous examples of Voronoi patterns, also known as Thiessen polygons or Dirichlet tessellations. I’ve been thinking about Voronoi patterns a lot lately because they have inspired our architecture friends in their visualizations of the science...

I snapped this photo in my backyard while enjoying the last bit of the summer holidays – just look at how busy this little critter has been, flying from flower to flower, collecting pollen. I’m fascinated by the role that physics plays in pollination, and not just the unlikely aerodynamics of bumblebee flight. Electricity plays...

Our amazing crew at Royal City Science has been brainstorming ideas for travelling exhibits that we can take to schools, festivals, Farmers’ Markets, etc. to share our passion for all things STEAM (science, technology, engineering, arts, and mathematics), while we fundraise to build a permanent home in Guelph. A blog post from the NFB recently...
