To accompany ‘A new device uses atoms’ quantum weirdness to peer underground’
- People use the term “quantum” all the time. What do you understand it to mean?
- Imagine you needed to know where buried things — such as structures or archeological artifacts — might lie below ground. How would you go about finding them? What tools would you use?
- How does the story define quantum physics? What makes effects in the quantum world different from those in our visible, everyday world?
- What are some ways to measure gravity?
- How does the new quantum gravity detector work?
- In what way does precisely measuring gravity help find underground objects?
- How did Michael Holynski and his colleagues test their detector in the real world? What role did a computer model provide for interpreting their findings?
- What are two advantages to the new gravity detector over previous systems?
- If you were a scientist or engineer who had access to this new gravity detector, what would you use it to search for — and why? Explain which of the new device’s advantages (as mentioned in the story) would make it a particularly good choice for this particular application?
- Of all of the potential applications for gravity detectors that you read about in the story, which do you think is most important? Explain your choice.
