A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Heat pumps move heat around, whereas radiators create it.
The "efficiency" of heatpumps relates to heat they import into a system for a given amount of power, compared to creating heat with that power. They are not generating that heat. They are moving it.
Similarly, it's much more energy efficient to use a wheelbarrow to collect ice and move it inside, than it is to make ice cubes in freezer.
