Nobody's teaching students to just do physics our way. I mostly study how heat moves through solids. In a lab, I make things really cold with a cryostat of liquid helium. Then I take a laser and heat it at just one spot and watch what happens. I study how heat moves through material-that seems like a situation really remote from reality because I have everything under control in a lab, but by looking at a controlled situation, I can figure out how heat moves in everyday situations.
Heat affects a lot of electronic equipment.
As people make circuits smaller, we need to make them so they don't overheat. It's not good for laptops to be on all the time. Laptops don't have good cooling systems. In the back of a big computer, there's a big vent for a fan that's going all the time. But laptops only pull air through the keyboard.
