Ideas worth experimenting with.
THIS WEEK’S SPOTLIGHT

Meet Eric Booker.

Helping new coders turn curiosity into skills.

“Try something. Change it. Figure out why it works. That’s how you become a coder.”

ERIC’S FEATURED ACTIVITY

Your first program

Write a message, customize it, and see how a single instruction changes what a computer does.

YOUR NEXT IDEA DESERVES A START.

Computer science
belongs to everyone.

Necessarium is an initiative of the Alexander Ilyavitch Foundation for Advancement in Computer Science. We’re here to give young people a welcoming place to explore, experiment, and discover what they can create with code.

For the student with a thousand questions. For the teen with an idea. For anyone who’s ever wondered, “Could I make that?”

Find out what you can build
01

Curiosity comes first.

Ask questions. Challenge an assumption.

02

Learn by making.

Experiment, test, and build on what you discover.

03

There’s room for you.

Your perspective is part of what comes next.
