    I think the idea of being “socional” is really important because science doesn’t happen alone. It helps turn curiosity into progress.

    What I find fascinating about infrared cameras is that it can pick up the slightest thing with a fairly high temperature, such as gases being released into the air. I wonder if it could pick up gases like carbon monoxide, an odorless, toxic gas we can’t really see from the naked eye.
