Introducing SpaceMath@NASA
SpaceMath@NASA will introduce you to the use of mathematics in today's scientific discoveries. Through press releases, citizen science and other hands-on projects, you will explore how even the simplest mathematics lets us explore the universe.
Featured Topic - Experimenting With Smartphone Sensors
Your smartphone has a dozen sensors that you can access using free apps. You can measure your acceleration, local temperature and magnetic fields, pressure and gravity just to name a few. Here are some interesting things you can do to get started!
Sound: ( Experimenters Guide )
- Create a catalog of the loudness of things in your environment
- Find the quietist place in your house or your environment
Magnetism: ( Experimenters Guide )
- Map your magnetic environment and find the weakest place
- Search for buried metallic treasure!
Light: ( Experimenters Guide )
- Measure the brightness of things in your environment
- Follow the change in sunlight intensity during the day and across seasons
Radiation: ( Experimenters Guide )
- How radioactive is your environment?
- What kinds of things produce the most radiation?
Citizen Explorers
These are short exploration projects that nurture your own journey of discovery by connecting you with some basic ideas in astrophysics and space science from eclipse observing to the Big Bang...and beyond!
Crowdsourcing Gravity and Earth's Rotation! - Earth's rotation causes a centrifugal force that makes the acceleration of gravity slightly less at the Equator than at the North and South Poles. Using a smartphone app called 'Gravity Meter' we can detect this change by using this app and making measurements at many different geographic latitudes. Gravity.
