Start your algebra journey here with
an introduction to variables and
equations.
Use diagrams and words to explore the
very start of algebra, with puzzles
and intuition guiding the way.

When you go down a curved slide,
your velocity is constantly changing
direction. Otherwise, you'd either
fly off the slide or fall straight
through. This means that your body
is constantly accelerating, as you
can see in this simulation. â
â
Newton's second law tells us that
force is mass times acceleration. So
when would you feel the most force?â

Using computer science, can you always
win at 20 questions? With a
perfectlydesigned algorithm, you
could reduce the number of
possibilities by half with each
question. With such an algorithm, you
could always win, even if you started
with 2^20 â 1 million possibilities. â
â
Such a mathematically perfect
algorithm isn't necessarily practical.
Even without mathematical perfection,
the right strategy is to ask questions
that split the field mostly in half.
With this strategy, a welldesigned
algorithm can easily guess correctly
any of the ~200,000 actors on
Wikipedia.â

Brilliant's newest computer science
course is Search Engines. In
this interactive course you'll learn
how to build a search engine and
master the search algorithms that
enable the internet we use today.
Along the way you'll add features to
a specialized search engine we built
for the course. Sherlock
searches through the 4 novels and 47
short stories by Sir Arthur Conan
Doyle, featuring the great detective
Sherlock Holmes.
Building
a searchable data structure for all
that information is tricky,
especially for the complex queries
required to solve the mysteries
you'll encounter.
