Scientists at Peratech have developed “spikey” particles for use in the touchscreen of smartphones. The breakthrough is that the quantum tunneling effect means that the screen is pressure sensitive.
I found this video on quantum tunneling on youtube.
I found this video on youtube. It is a good demonstration of electrons behaving like waves or particles, depending on their energy. Can you explain why the electron energy is important here?
There is a second video explaining how the electrons are produced if you are interested. Watch it here.
It’s a few months since we looked at centripetal acceleration in class but I thought I would share this article I found. I wonder how many people would dare to “co-write” a physics paper with Isaac Newton? The article is worth a read and I have attached a download link below.
While we’re talking about centripetal acceleration, Rhett Allain’s blog post that led me to the article is also very interesting.
