Our nation’s continued economic prosperity is closely linked with student success in the fields of science, technology, engineering and mathematics (STEM). Use these resources to explore the critical role STEM education plays in driving innovation, and how schools and districts can expand the capacity and diversity of tomorrow’s STEM workforce.

IOT (Internet of Everything) and embedded system are taking over. How to understand, How to adapt, and are we ready.
We use computers to play games, write letters, watch movies, and many other tasks, but do we know what is inside the computer? Lets explore what is inside the compter and how it works.
We hear sounds all around us, but what is sound, and how do we hear it. Lets explore how it is csaptured and reproduced in our music players.
What is electricity? Where does it come from?
Where do electrons in electricity come from? How can we use magnets to create electricity? Lets explore how we go from Atomic particles to their use in producing electricity.
Where does electricity come from? How do we create it? What is the relationship between magnets and moving electricity? We will try to explain this phenomenon.
What to understand how to create an editor? Here are some tutorials to help you learn about creating some in C.
The electric car adaption has been greatly accelerated by a startup company named Tesla. This upstart car company, as of July 1, 2020, is the most valuable car company in the world, and has redefined electric cars.
But why is Tesla so popular? How is Tesla’s approach different than Ford? Isn’t an electric car just a different motor in a normal car? How does driving an electric car differ from driving an ICE (internal combustion engine) car? How is an electric car different or the same an ICE car?
Personal web servers are a great way to save manuals, interesting links, trip memories, and many other bits and pieces of information.
We are going to create a home Wiki using a Raspberry Pi and a USB hard disk. This will be a headless server, meaning that it can live anywhere it can connect to your network.
Text documents, Word documents, PDF files, Markup documents, Markdown documents, Web pages, *.docx, *.html, *.odt, *.tex confused yet? On a computer we have multiple types of documents to express thoughts, ideas, or just letters. Lets look at some methods of marking documents.
Now that we know what types of documents we are creating, how can we use them in a wiki or a web browser.
How is sound created?
How does sound travel?
How do we hear sound?
Frequency and Wavelength
Amplitude and Volume
Music vs Noise
How do we record sound? How do we measure sound? How do we modify sound? How do we recreate sound?
Why does the same song sound different at home, or in the car, or over ear buds from my phone?
Come along as we look at how sound is converted into electrons, recorded onto media, manipulated, and finally spit out to our ears. What we take for granted when listening to music, is really a wonder of complexity, but moves our ears to joy.
