The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense!

In this episode, Shini takes us into the world of magnetism!

What is light? That is something that has plagued scientists for centuries. It behaves like a wave... and a particle... what? Is it both?

e=mc2... it's a big deal, right? But why? And what about this grumpy cat in a box and probability? In this episode, Shini attempts to explain a little more on the topic of quantum mechanics.

Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time!

"Marie Skłodowska Curie’s revolutionary research laid the groundwork for our understanding of physics and chemistry, blazing trails in oncology, technology, medicine, and nuclear physics, to name a few." Watch this video to learn about her amazing discoveries.

The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time.

Universcale provides a look at objects from sub-atomic particles to red giants and all things in between using an interactive scale. This graphically beautiful tool is an outstanding way to measure and compare objects of different sizes.

Click on the icons to find out how Canadians are finding innovative ways to reduce their energy use. You can also compare the energy use of the provinces, On the Move and At Home.

In this video, the creator "examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond." (site)

Should you give your cooking oil a useful new life as biodiesel, a biodegradable energy source which can run in diesel engines instead of refined petroleum? This video describes the process of turning used oil goop into viable fuel.

Biofuels can provide energy without the reliance on environmentally harmful fossils fuels but scientists are still searching for a plentiful source. This video demonstrates how cellulose, the naturally abundant tough walls of plant cells, might be the solution.

This video examines renewable energy and some of the challenges of exchanging our fossil fuel dependence for only renewable energy sources.

In this animated video, the game board is Earth and all the Tetris blocks represent CO2, a greenhouse gas that is piling up as we burn fossil fuels. The video explains how this overload of CO2 leads to climate change and reminds us that, unlike Tetris, we won't get an opportunity to start over.

This video explains hydraulic fracturing, or “fracking,” that extracts natural gas from deep underground. How does fracking work and why is it controversial?

Is it possible that one day the world could be completely reliant on solar energy? This video examines how solar panels convert solar energy to electrical energy.

This animated TED video uses billiards to illustrate tipping points, chaotic motion and their implications on climate change. Learn about how rising CO2 levels in the atmosphere increase Earth’s temperature and lead to huge, unpredictable changes elsewhere.

Watch this animated video to learn how solar towers and panels work and why cloud cover is an important factor in the future of solar energy production.

Keystone plant genera are unique to local food webs within ecoregions. Remove keystone plants and the diversity and abundance of many essential insect species, which 96% of terrestrial birds rely on for food sources, will be diminished. The ecosystem collapses in a similar way that the removal of the “key” stone in ancient Roman arch will trigger its demise.

Can plants talk to each other? It certainly doesn’t seem that way: They don’t have complex sensory or nervous systems, like animals do, and they look pretty passive. But odd as it sounds, plants can communicate with each other — especially when they’re under attack.

For several centuries, people thought diseases were caused by wandering clouds of poisonous vapor. This video describes how scientists worked to prove "germ theory" and changed how we see and prevent disease.

Why are some germs relatively harmless, while others can be fatal? This video describes how germs are passed around and offers new ideas to control them.
