Today we answered some of our bigger questions that emerged from wondering how long light from Earth takes to get to the moon. We used this to explore scientific notation, exponents, large numbers and more.
When I have big questions one of my favourite Youtube Geekery Channels is minute physics - hope you like it too.
We wondered if light would travel forever in the universe and if we could see the light (from a torch) on the moon when we turned it on and off. What can we see from the moon on Earth?
More questions emerged after these videos
what is the speed of light in a vacuum (space)?
what is the speed of light in water (space)?
can animals see more stars than us?
Here are some cool geek videos that answer questions but make you ask even more...
and this for does the torch light beam widen and more
Stuff about Mathematics - this blog was set up for the Mathematicians at my school in Thailand. I migrated the contents when I left, so please excuse any images that didn't make the journey. They are bouncing around somewhere in the blogosphere. Image is from my travels in Argentina, 2013. The beautiful natural geometric patterns found in Humahuaca 2013
