PoW taking place: math problem-solving moment of the week
"The scalene was the hardest for me, but I still figured it
out! I knew that in a scalene triangle, it wouldn't be the
same lengths on any side...."

The On-Line Encyclopedia of Integer Sequences (OEIS) is closing
in on a trio of milestones: 50 years, 250,000 sequences, and
the 75th birthday of Neil J. A. Sloane, who started the
database in 1964 during his graduate studies.
The Center for Discrete Mathematics & Theoretical Computer
Science (DIMACS) of Rutgers University will celebrate by
hosting a conference next month to discuss the challenges and
research advances in the computational sciences that can be
attributed to the OEIS:
To discuss sequences, propose a new one, update an existing
entry, or see a list of citations to hundreds of the research
articles and books that have referenced the OEIS — first

Now taking place: math education conversation of the day
"I was wondering if anyone here has any experience or
knowledge of attempts to extend the Koch Curve into three
dimensions. The result should relate to the Koch in roughly the
way that the Menger Sponge can be considered a 3D extension of
the Sierpinski Carpet, or the way that the Sierpinski Pyramid
can be considered a 3D extension of the Sierpinki triangle.
I've had a go at this and found one solution. I guess I have
two main questions...."

The puck drops to start the regular season of the National
Hockey League (NHL) in a couple Wednesdays — with the League
shooting for new goals, in science, technology, engineering,
and math (STEM).
To energize student interest in STEM topics, the NHL, the
National Hockey League Players Association (NHLPA), and
education technology company EverFi have launched free
interactive education opportunities for each of the 30 NHL team
markets in the United States and Canada, plus hundreds more
communities. Called Future Goals™, the program leverages the
game of hockey as a learning vehicle to understand STEM in the
real world, to introduce students to STEM career
opportunities — and to do so in a safe and responsible way.
In the Future Goals online course Ignition, students learn the
nuts and bolts of how technology works in virtual environments
where they address issues of digital citizenship. The Ignition
curriculum aligns with the National Educational Technology
Standards (NETS), and fulfills the objectives of the Children's
Internet Protection Act (CIPA).
